The fastening member is provided with a fitting portion connected with the first body. The fastening member is provided with a third threaded portion. The second adjusting member is provided with a fourth threaded portion screwed into the third threaded portion.

A torque structure includes a first body set, and a second body set. The second body set has a torque slip function. The second body set includes a second body, a drive head, a resisting module, a plurality of balls, and a mounting ring. The second body is provided with a third receiving recess and a plurality of ball slots. The drive head is connected with the second body. The resisting module is received in the third receiving recess and includes a first abutting element. The mounting ring is mounted on the second body and has an interior provided with a fourth receiving recess. The balls are received in the ball slots and located between the first abutting element and the fourth receiving recess.

A flex clipper provides a feature to help the cutting blade set float more effortlessly by adjusting automatically to the contours of a client's head to prevent getting stuck and causing cuts and irritation to the scalp. The hair clippers preferably also uses a self-contained motor-driven adjustment mechanism to adjust the relative position of the stationary and reciprocating blades of a common type of blade set. Two momentary switches operable by the thumb of the hand holding the clipper afford a barber total automatic adjustment with the clipper itself in an on or off condition.

A torque wrench is provided, including a main body, a driving portion, a positioning member, a torque adjusting assembly and a tripping assembly. The main body defines an axial direction. The driving portion is disposed on an end of the main body. The positioning member is fixedly disposed in the main body. The torque adjusting assembly includes an abutting member and a mandrel, and the mandrel is disposed in the main body, rotatable about the axial direction and screwed to the abutting member. The tripping assembly includes an elastic abutting member and a plurality of notches arranged circumferentially one of the elastic abutting member and the plurality of notches is disposed on the mandrel, and the other of the elastic abutting member and the plurality of notches is disposed on the positioning member.

A torque connector structure includes a first body, a second body assembled with the first body, a first drive member assembled with the first body, a second drive member received in the first body and having a plurality of first receiving grooves each having a cylindrical shape, a third drive member received in the first body and the second body, a fourth drive member mounted on the third drive member and having a plurality of second receiving grooves, an elastic member biased between the first drive member and the second drive member, and a plurality of pins received between the first receiving grooves and the second receiving grooves. The second drive member and the first drive member are driven simultaneously.

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 golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

A tool for a bone implant includes a rod and an adaptor. The rod includes a coupling portion having a through-hole. The rod further includes a measuring arm connected to the coupling portion and a force applying arm connected to the coupling portion. The measuring arm includes a first extension section having a first indicator portion, and the force applying arm includes a second extension section having a second indicator portion. The force applying arm is elastically deformable away from the measuring arm to displace the second extension section relative to the first extension section. The adaptor is coupled in the through-hole and includes an outer ring and an inner ring. The outer ring is rotatable relative to the inner ring in a single direction.

A clamp includes a jaw assembly, and an actuator device for moving the jaw assembly between clamped and unclamped positions. The actuator device includes a handle, and a keyed shaft coupled to the handle via a spring biased releasable torque transfer mechanism.
