The most commonly used manual torque wrenches, in addition to electric torque wrenches, pneumatic torque wrenches, etc.

Structural torque wrench is also called torque meter, torque screwdriver. It is designed based on the bending principle of the beam, the bending principle of the torsion bar and the compression principle of the coil spring, and it can measure the torque acting on the nut DIN 1478 turnbuckles.

There are two types of torque wrenches: flat type and dial type. The torque wrench has a long elastic rod. One end is equipped with a handle, and the other end is equipped with a square or hexagonal head. A replaceable sleeve is fitted on the square or hexagonal head and is clamped by a steel ball. There is also a long pointer on the top. The scale plate is fixed on the handle base, and the scale value of each grid is 1N (or kg/m).

Before use, adjust the indicator installed on the wrench to the required torque, and then pull the wrench. When the predetermined torque is reached, the pointer on the indicator will rotate to the pin shaft, and finally the pointer collides with the pin shaft. , Inform the operator through speaker signal or sensor signal.
