Working principle of torque wrenchThe principle of producing cata sound from torque wrench (torque wrench) is very simple and can be understood in the following steps: 1, the torque wrench in the sound of "cata" is the prompt has reached your required torque value; 2. The "cata" issued by the torque wrench is generated by its internal torque release structure, which is composed of three structures: pressure spring, torque release joint and torque push rod. 3. First, set the required torque value on the torque wrench (the spring sleeve on the push rod exerts pressure on the torque release joint), lock the torque wrench and start to tighten the bolt. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), the effect of instant disconnection will be produced. At the moment of the disjointed effect, a joint strike, the wrench metal shell issued by the "cata" sound. This confirms that the torque value is being reached as a reminder (in fact, it is the same principle that our arm joints will hit the steel tube when they are bent at 15 degrees and straightened in an instant). |
