Description
Technical Field
[0001] The utility model relates to the field of torque wrenches, in particular to a torque wrench with a marking function. Background Art
[0002] A torque wrench, also known as a torque wrench or torque wrench, is a tightening measuring instrument with a torque measuring mechanism. It is mainly used to tighten bolts and can measure the torque value when tightening. The working principle of the torque wrench is based on the bending principle of the beam, the bending principle of the torsion bar and the compression principle of the coil spring, and can measure the torque acting on the bolt. After using the torque wrench to tighten the bolt, in order to ensure that the torque value of the bolt does not change during subsequent use, and also for the convenience of maintenance, the operator often makes a mark on the head of the bolt and the workpiece fastened by the bolt. In the subsequent maintenance process, the operator can quickly determine whether the bolt is loose through this mark. When the operator needs to tighten multiple bolts at one time, it is necessary to make multiple marks at one time, which greatly reduces the work efficiency. In addition, after working for a long time, the operator is very likely to mark the mark crooked, which will have an adverse effect on the subsequent maintenance and inspection. Therefore, a torque wrench with a marking function is needed to solve the above problems. Utility Model Content
