[0002] Torque wrench, also known as torque wrench, torque adjustable wrench, is a type of wrench. According to the power source, it can be divided into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench; manual torque wrench can be divided into: preset type, fixed value type, dial type, digital display type, slip type, bending type, and kilogram wrench. When the tightness of screws and bolts is critical, the use of a torque wrench allows the operator to apply a specific torque value.

It is very practical in daily use. It is placed above the placed torque wrench through a fixing rope, and then the first nut is rotated on the surface of the first threaded rod, and the first threaded rod is fixed to the fixing plate together, so as to fix the torque wrench and prevent the torque wrench from shaking during the calibration process, thereby affecting the calibration result.

It is possible that some torque wrenches cannot be placed in parallel on the first support column and the second support column, and the applicability is insufficient.
