Abstract: A torque limiter can include a housing and a shaft. The housing can include a housing magnet enclosed within the housing. The shaft can be at least partially surrounded by the housing and can be rotatable within the housing. The shaft can include a shaft magnet integrated with the shaft to magnetically couple with the housing magnet to transmit a torque between the housing and the shaft and configured to uncouple from the housing magnet allowing the shaft to rotate within the housing when a threshold torque is reached.

Abstract: A palm wrench includes a C-shaped body and a driving head. The driving head is pivotably and rotatably located within the body. The body has an opening, and the driving head has two function ends on two sides thereof. The driving head is pivotably connected to the body by two pivots which extend through the body and are connected to the driving head. The driving head can be rotated with respect to the body, and the user can grapes the body to rotate the driving head to output torque.

Abstract: A tool element has a body and an anti-skid collar. The body has an external surface, a connecting end, an operating end, a mounting recess and multiple notches. The mounting recess is annularly formed round the external surface of the body between the ends and has a bottom face. The notches are formed on the bottom face of the mounting recess at intervals. The anti-skid collar is an annular collar, is detachably mounted around the body and has an inner surface, an outer surface, a holding face and an anti-skid face. The holding face is formed on the inner surface and is rubbed against the notches of the body to hold the anti-skid collar securely on the body. The anti-skid face is formed on the outer surface of the anti-skid collar.

Abstract: A wrench, comprising: a body, includes a handle having an appropriate shape, a containing groove disposed at an action end of the body; a ratchet is pivotally coupled to the containing groove of the body; a seal cover is covered onto the body and matched with the shape of the containing groove and the second containing groove of the body; a latch ring is latched to the latch slot of the body and the groove, such that the ratchet is pivotally coupled into the containing groove of the body, and the seal cover is sealed onto the body.

Abstract: A torque device for use in tools comprises a tubular member; a bit receiver axially received at the front end of the tubular member and its front end may couple with tools; a shank inserted at the rear end of the tubular member and including a resilient element fitted thereon, and including a receiving chamber formed at the rear end thereof for receiving a driving tool, and a selector mechanism defined between the shank and the bit receiver; a fitting sleeve fitted on the shank for biasing against the resilient element and including inner threads arranged on the inner wall thereof, between the fitting sleeve and the tubular member being provided with a guiding mechanism; an adjusting member fitted at the rear end of the shank including outer threads for screwing with the inner threads of the fitting sleeve, and between the adjusting member and the tubular member being fixed a confining mechanism.

Abstract: Screwdriver with changeable operation modes, including: a handle having a slide way formed in the handle and passing through a front end of the handle; a stem, a rear end of which is slidably fitted in the slide way without detaching from the handle; a clutch mechanism connected between the stem and the handle, in normal state, the clutch mechanism being in a non-transmission state, whereby the stem can freely rotate within the handle; and a rotary member connected with the stem for a user's hand to rotate. When the screwdriver is used to screw a screw in a loosened state, the user can turn the rotary member to rotate the stem. In the case that the screw is in a tightened state, the handle is pressed to move the stem inward, the clutch mechanism is in a transmission state and the user can turn the handle to drive the stem.

Abstract: A tool kit with illuminating function, having a grip and a transparent cover shade connected with the front end of the grip. A front tool connecting section of the transparent cover shade is detachably connected with a tool kit tightened and fixed by a fixing cap. A user can rotate a cover board to align a taking hole thereof with the engaging hole of the main body of the tool kit so as to conveniently take out the tool head. When the taking hole is disaligned from the engaging hole, the tool head is prevented from dropping out so that the kit of tool heads can be reliably located in the tool kit.

Abstract: This binder (10) includes a front cover (12), a rear cover (14) and a spine (16) and is provided with a transparent label holder (50) which extends across the spine (16) and is attached to at least one of the covers (12,14). The label holder (50) provides an open upper margin (52) and is attached at the side margins (60, 62) and at least partially attached at the lower margin (54) to retain the label (100) which thereby has an increased area for label information.

Abstract: A speed handle which includes a ratchet drive on the working end. A conventional socket can be attached to the mounting end of the ratchet drive. The speed handle is especially useful in areas where there is very little room for operating a conventional wrench or conventional ratchet wrench.

Abstract: A screwdriver includes an elongated shaft including a first engagement surface, and a handle including a second engagement surface opposing the first surface. The handle receives the shaft and allows limited axial movement of the shaft relative to the handle in a direction parallel to the longitudinal axis of the shaft between a rotation transmitting position in which the first and second engagement surfaces are in contact with one another during rotation of the handle and a disengaged position in which the first and second engagement surfaces are out of contact with one another during rotation of the handle. The first and second engagement surfaces mate with one another to prevent relative sliding movement between the surfaces when they are in contact with one another so that the handle and shaft rotate together when the shaft is in the rotation transmitting position. The shaft rotates freely relative to the handle when the shaft is in the disengaged position, and is biased toward the disengaged position.

Abstract: A plurality of inwardly facing ratchet teeth is integral with the walls of a cylindrical retainer cavity within the hollow cylindrical retainer. A washer is mounted around the generally conduit head and is sandwiched between an external head flange and an internal retainer flange. A snap ring is positioned in the head recess in order to provide friction for the washer in conjunction with maintaining the retainer around the open end. The ratcheting tool driver includes a generally solid cylindrical switch rod has a first rod end and a second rod end with a rod recess surrounded by a hollow neck. A pawl is provided with a pawl recess.

Abstract: A method of assembling a ratcheting tool driver is disclosed. The tool driver has a plurality of inwardly facing ratchet teeth integral with the inner walls of a hollow cylindrical retainer. A switch rod carries a spring-biased pawl in engagement with the ratchet teeth.

The ratcheting tool driver includes a generally solid cylindrical switch rod has a first rod end and a second rod with a rod recess and a pawl with a pawl recess. A pawl spring bias is seated in the pawl recess and in the rod recess such that when a switch button rotates the switch rod in a predetermined direction the pawl spring bias forces the pawl to shift within the head slot and engage one of the plurality of inwardly facing the ratchet teeth of the first cylindrical retainer cavity.
