Abstract: An electronic torque wrench a wrench head unit adapted to engage and turn a fastener, a tubular first wrench body securely engaged with the wrench head unit, a tubular second wrench body coupled and aligned with the first wrench body by a fitting member to permit rotation of the second wrench body relative to the first wrench body, a mounting shell sleeved on the second wrench body for mounting a display unit to provide a display representing a measured torque. By rotation of the second wrench body, the display unit can be adjusted to a desired angular position for being viewed easily by the user.

Abstract: A tool for loosening and/or unscrewing a screw in an object. The tool includes a frame dimensioned and configured to receive (or be mounted on) an object having at least one screw removably embedded therein.

Abstract: A driving device includes a driving shank, a magnetic member mounted in the driving shank, a stop ring secured in the driving shank to stop the magnetic member, and an elastic member biased between the driving shank and the magnetic member. The driving shank has a first end provided with a mounting post and a second end formed with a mounting hole and a receiving chamber. The stop ring has an inner wall formed with a through hole and an outer wall provided with a toothed portion engaging a peripheral wall of the receiving chamber. The magnetic member has a peripheral wall formed with a stop flange that is movable to abut the stop ring. Thus, the elastic member provides a buffering effect to the magnetic member to reduce the pressure applied on the magnetic member.

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 movable wrench including a screw bar, and an operating element. The bottom surface of the screw bar is urged by a first compressible spring. The hook part of the operating element urges against the bottom surface of the screw bar. As the user depresses the operating end of the operating element, the hook part escape from the bottom surface. The first compressible spring is depressed downward. After the reverse rotation and positioning, the first compressible spring urges against the screw bar again. The operating end is released so that the hook part urges against the bottom surface again.

Abstract: A tool device includes a tool shank having a noncircular engaging hole for slidably receiving a socket member which includes a noncircular bore for engaging with various fasteners, a biasing device may bias the socket member outwardly relative to the engaging hole of the tool shank, and an anchoring device may slidably anchor the socket member to the tool shank. One or more socket members may be replaced with each other and may be selectively engaged into the engaging hole of the tool shank, for receiving and driving various tool members of different sizes or diameters or dimensions.

Abstract: An adjustable wrench includes a fixed body having a first end formed with a fixed jaw, a mediate portion formed with a mounting portion and a second end formed with a receiving recess, and a movable body movably mounted on the fixed body and having a first end formed with a movable jaw facing the fixed jaw and a second end formed with a mounting edge slidably mounted on the mounting portion. Thus, the fixed body has a substantially H-shaped mounting portion, and the movable body has a substantially C-shaped mounting edge slidably mounted on the mounting portion of the fixed body, so that the movable body is mounted on the fixed body rigidly and stably.

Abstract: A ratcheting adjustable wrench is disclosed. The wrench has a main body defining a wrench head, handle and fixed jaw. The main body is fabricated of hardened sheet metal formed from laminations. The adjustable wrench has a pin/slot guide mechanism to retain and provide position adjustment for an adjustable jaw. A locking mechanism allows the adjustable jaw to ratchet over the corners of a fastener being tightened. In a locked position, the wrench operates like a standard adjustable wrench. Moving a trigger to an unlocked position allows the worm gear mechanism to shift axially for additional travel. The movable jaw engaged to the worm gear is thereby also allowed to shift position so that the adjustable jaw wrench can rotate over the points of the fastener being torqued.

Abstract: A ratcheting adjustable wrench, having a handle assembly and a head assembly. The handle assembly is pivotally attached to the head assembly. The head assembly includes a fixed jaw and a movable jaw which together may engage a nut. An opening, having an opening top and an opening bottom extends laterally through the fixed jaw. A shaft spans the opening from the opening top to the opening bottom. A rack having teeth is rigidly attached to the movable jaw. A worm gear is slidably mounted on the shaft, which is attached to the fixed jaw and engages the rack. The handle has a contact point which selectively urges the worm gear against the opening top of the fixed jaw to maintain the position of the fixed jaw with respect to the movable jaw to torque the nut.

Abstract: An adjustable socket wrench with bolt head locking arm for engaging, removing and replacing different size bolts in a work piece. The socket wrench is designed to engage a bolt head at right angles and when locked on the bolt head holding the head with zero tolerance for ease in loosening and tightening the bolt. The wrench includes a wrench body with an upper end portion, a middle portion and a lower end portion. A channel is cut across the width of the upper end portion of the wrench body for receiving a first sliding jaw and a second sliding jaw. The bolt head is received between the first and second jaws. A first jaw guide arm is pivotally mounted on the wrench body with one end of the first jaw guide arm engaging the first jaw. A second jaw guide arm is pivotally mounted on the wrench body with one end of the second jaw guide arm engaging the second jaw. The first jaw guide arm is pivotally mounted to the bolt head locking arm. The bolt head locking arm in turn is pivotally mounted to a first pivot arm.

Abstract: A universal hand tool for a bicycle, including a head section having a movable clamping arm and a fixed clamping arm defining a clamping slot, and a handle section formed with multiple hexagonal holes. The movable clamping arm is disposed with a thread sleeve and fitted on a thread rod of the head section, whereby the movable clamping arm is movable by means of rotating the thread sleeve. A scale ruler is disposed above the thread rod for measuring the sizes of the nuts clamped in the clamping slot. The head portion is formed with a large and a small recesses and cooperative first and second projections under the thread rod for tightening/untightening slotted nuts. A hinge member secured on one side of the head section and the handle section to pivotally connect the same. The head section further has a rectangular recess and the handle section has a corresponding rectangular projection.
