A torque wrench may include a head having a driving member configured to be operably coupled to a socket, a handle, a lever arm operably coupled to the head and the handle at respective opposing ends thereof, and a torque adjuster configured to enable a torque setting of the torque wrench to be adjusted. The torque adjuster may include a fixed member affixed to the lever arm and a movable member operably coupled to the fixed member. The handle may include a first end cap at a distal end thereof relative to the head and a second end cap at a proximal end thereof relative to the head, the second end cap being disposed proximate to the movable member.

A screw driving tool includes a torque output element which defines an axis and is mounted in a housing, a torque transmission section with a plurality of depressions, and a torque transmission element, which is pretensioned by the force of a force accumulator and engages into at least one of the depressions, for coupling the torque transmission section to the housing so as to transmit a torque. The coupling is released when the torque transmission element leaves the depression in an edge-controlled manner against the force of the force accumulator, which is adjustable by an adjustment device, when a limit torque is exceeded. A switchover element is movable from a release position into a blocking position and allows the torque transmission element to leave the depression in the release position but blocks the torque transmission element in the blocking position.

A torque wrench has a lock device, which includes a locking sleeve, a restoring elastic member, a clamping member, a locking hole, a locking member, and a positioning assembly. The locking sleeve is provided with an accommodating recess, an abutting portion, and a positioning recess. When the lock device is in a lock position, the locking member is pushed by the abutting portion and pressed against a hollow shank to restrict a handle from rotating relative to the hollow shank. When the lock device is in an unlock position, the locking member is detached from the abutting portion, so that the handle is rotatable relative to the hollow shank.

A torque structure includes a first body, a second body, an elastic member, and a locking set. The first body has a receiving chamber. The second body is provided with a drive portion, a plurality of first securing portions, and a first end face. The locking set includes a locking member, a plurality of securing members, a plurality of balls, and a washer. The locking member is provided with a pivot portion, a plurality of second securing portions, and a second end face. The securing members are mounted in the first securing portions and the second securing portions. The washer is mounted on the locking member elastically biased between the first end face and the second end face to space the second body from the locking member. The washer eliminates a gap between the locking member and the second body.

A torque wrench having post-torque rotation setting and measurement function, optionally including auto transition from torque to angle rotation, which may operation with and without batteries, including low profile design, improved visual, audio and haptic feedback, a recesses pawl seat for improved accuracy and longevity and improved handle rotation for torque setting and spring unwinding by virtue of improved torque setting nut design.

An apparatus for applying torque to a body includes a base defining an inner chamber. The apparatus includes a plurality of pins supported by base and disposed in the inner chamber, the plurality of pins moveable relative to the base between engaged positions and disengaged positions. The apparatus includes a trigger actuatable to move at least one of the plurality of pins to the disengaged position.

A torque output device includes a body with an opening in the top. A top toothed part is located beneath the opening and includes a bore located corresponding to the opening. The top toothed part includes multiple top teeth. A drive shaft secured in the body and includes a central hole in which a rod is located. A driving portion is formed to the lower end of the drive shaft. The drive shaft and the top toothed part are freely rotated relative to each other. A bottom toothed part is mounted to the drive shaft and freely moves up and down relative to the drive shaft. A resilient member is mounted to the drive shaft and biases the bottom toothed part. A pressure collar is threadedly connected to the lower end of the body to set the torque between the engagement of the top and bottom teeth.

A torque wrench has a hollow tubular body. A long rod and a short rod are provided in the hollow tubular body. The hollow tubular body is formed with a first through hole and a second through hole respectively corresponding to the long rod and the short rod. A first limiting unit is provided in the first through hole, and a second limiting unit is provided in the second through hole. The first limiting unit enables to slide into a first gap spaced apart between the long rod and the hollow tubular body to limit the swing range of the long rod, and the second limiting unit enables to slide into a second gap spaced apart between the short rod and the hollow tubular body to limit the swing range of the short rod, thereby improving the accuracy of the tripping torque and making the torque wrench easy to calibrate.

A dual-beam torque wrench with a linear display and a linear locking member is provided. The torque wrench includes a head that couples to a socket to rotate a fastener or bolt. A housing of torque wrench extends from the head to form a handle. Within the housing forming the handle are two beams: a lever beam that transmits the force from the handle to the head and a deflecting beam that couples to the head and not the handle. The deflecting beam deflects away from the lever beam to indicate that a predetermined torque has been applied. A torque adjustment assembly moves the lever beam relative to the head to set the predetermined torque, and a pin follows the linear display to indicate to the user the set predetermined torque.

An instrument for holding and torque control tightening of a threaded implant device with an extender, the instrument including a frame forming a gripping handle and a holder, an elastic device that is arranged at the frame to provide a predefined elasticity to the frame, and a torque measurement device arranged on the frame, wherein the holder is configured to (i) removably hold the threaded implant device and to (ii) hold the extender for tightening the threaded implant device to an object after the threaded implant device has been removed from the holder, and the torque measurement device is configured to measure a torque applied to the threaded implant device via the extender by a deformation of the frame.
