  • Patent number: 7225709
    Abstract: A connector for easily secure a socket thereon includes an axle rotatably received in an axial recess in an end of the connector and an inclined slot is defined radially in the body. A spring is biased between a first end of the axle and an inside of the axial recess. A guide portion such as a concavity with various depths is defined in a second end of the axle. A ball is movably engaged with a radial hole in the end of the body and operatively in contact with the concavity. A controller is rotatably mounted to the body and a pin extends through a hole in the controller and the inclined slot and is engaged with a receiving hole in the axle. The pin is automatically rotated backward by the spring when the user releases the controller.

  • Patent number: 7100481
    Abstract: A wire stripper has a pair of elongated frames pivotably joined together by a pivot pin and defining handles and jaws. The handles are covered by sleeves which include thumb wells which cover the ends of the pivot pin. A mechanical interlock is provided between the handles and the sleeves. The sleeves have slots for receiving the handles. The slots are offset so the front and rear surfaces of opposite sleeves are coplanar. The sleeves have a core and cushion grip overmolded on the core. A molding projection on the core allows precise placement of the core in a mold during formation of the cushion grip. A spring biases the frames to an open position. A locking member can be set by a sliding motion toward the handle end to hold the handles in a closed position. A curved shoulder on the edge of a handle wipes across a screw hole opening in the opposite jaw to provide a screw cutting function with a slicing action.

  • Patent number: 6923094
    Abstract: A tool has a pair of elongate housings adapted to be joined together in a housing assembly for enclosing and supporting a flexible drive mechanism entrained about a pair of rotatable elements. Each of the rotatable elements is disposed on the housing assembly at opposite ends thereof. A flexible drive mechanism provides a transfer of power between the rotatable elements so that rotation of one rotatable element at one input end of the housing assembly will effect driven rotation of the other rotatable element at an output end of the housing assembly. The elongate housings include male and female configurations for aligning and joining the housings without independent fasteners.

  • Patent number: 6895837
    Abstract: A wrench structure includes a wrench body having a handle portion. The handle portion is formed with a reinforcement portion having a first side formed with a first holding portion and a second side formed with a second holding portion. The first holding portion has a plane vertical to that of the second holding portion. Thus, the user's hand and the holding portion of the wrench body have a larger contact area, so that the holding portion of the wrench body can apply a larger force and torque to drive and rotate the workpiece, such as the nut or the like.

  • Patent number: 6832531
    Abstract: A tool has a pair of elongate housings adapted to be joined together in a housing assembly for enclosing and supporting a drive mechanism between a pair of oppositely disposed rotatable elements. The drive mechanism provides a transfer of power between the rotatable elements so that rotation of one rotatable element at one input end of the housing assembly will effect driven rotation of the other rotatable element at an output end of the housing assembly. The input end of the housing is provided with a first interlock configuration overlying and encircling the input end rotatable element. A motor mechanism is coupled to the input end of the housing assembly and has a rotatable drive shaft which passes entirely through and drives the input end rotatable element. The motor mechanism is integrally formed with a second interlock configuration identical to and matingly engageable with the first interlock configuration.

  • Patent number: 6792835
    Abstract: A tool assembly includes a multi-purpose tool, an adaptor and a socket wrench. The multi-purpose tool includes a body that contains implements such as knives, openers, scissors and other such devices. A fixed plier jaw extends from the body, and a movable plier jaw pivots about the body to a closed position against the fixed plier jaw. The closed plier jaws include an opening that surrounds and engages a driven section of the adaptor. The driven section includes an elongated cross-section to form a long torque arm within the closed jaw opening. A flange at each end of the driven section holds the adaptor in an axial direction. A universal socket may be attached to the driven end of the adaptor to provide a wrench suitable for many fastener shapes.

  • Patent number: 6769329
    Abstract: A ratchet wrench with a releasable socket which is rotatable in a handle circular pocket and the socket extends on the wrench for only the thickness of the handle and does not protrude beyond the handle. The socket is symmetrical in its configuration and is therefore reversible in its position in the pocket and it still produces the same rotational drive. A pawl and spring are on the handle, and the pawl is snug with the socket to hold the socket in an axially fixed position on the handle. The pawl protrudes from the handle and indicates the rotational drive direction required of the handle. Fluid clean-out holes extend into the pocket.

  • Patent number: 4873899
    Abstract: An adjustable ratchet wrench (10) for turning a shaft (12) having a key (14). The ratchet wrench (10) includes a socket element (22) received within the head (18) of the wrench. The socket element (22) has an inner diameter (24) in which a key receiving slot (27) is formed. The socket element (22) is operatively connected to the head (18) by a ratchet mechanism (28). The inner diameter (24) of the socket element (22) is effectively modified by positioning a crescent block (38) within the inner diameter (24) of the socket element (22). The crescent block may take the form of a jaw (39) or a bushing (52). The jaw may include one or two jaws which are shifted radially by an adjustment screw (45) relative to the socket element (22). The bushing (52) includes a retention mechanism (56, 57) for securing it within the inner diameter (24) of the socket element (22).

  • Patent number: 4869139
    Abstract: A driver with automatic speed and torque switching including two different drive trains which operate in parallel and are driven at the same time by a motor. One drive train provides a high-speed output while the other provides a low-speed output. A single drive head for transmitting torque to the nut is normally coupled to the high-speed output, and not to the low-speed output. The machine operates initially at the high speed for the "free rotation" of the nut. When the nut contacts the surface of the structural body, the drive coupling to the high-speed output is disabled, and the low-speed output (which formerly was not coupled to the drive head) is not at the same time coupled to the drive head. The nut is then driven much more slowly but with a higher driving torque. Within the low-speed drive train there is included a friction clutch, and adjustment means for adjusting the level of torque at which it will slip.

  • Patent number: 4864898
    Abstract: An opener for both pop-top cans and bottles is formed to include an elongated lever body. A lifting element is positioned on the lever body and is sized and shaped to fit underneath the lift tab on a pop-top can. A fulcrum element is further formed on the lever body in physical association with the lift element but spaced away from the lift element so as to form a channel between the lift element and the fulcrum element. The channel is sized and shaped such that the lift tab of the pop-top can can be sheaved in the channel between the lift element and the fulcrum element for manipulation of the lift tab to open the pop-top can. The opener further includes a bottle cap edge gripper located on the lever body in physical association with the fulcrum element. For removing bottle caps from capped bottles, the bottle cap edge gripper is independently formed and then positioned on the opener such that it engages the edge of the bottle cap when the fulcrum element is positioned in the center of the bottle cap.
