扳手Wrench主要用于擰緊拆卸螺栓螺母專用扳手！

Wrench Wrench is mainly used for tightening the special wrench for removing the bolt and nut

Under normal circumstances prohibit the use of torque wrench to remove the bolt. It is mainly because a bolt corresponding to the corresponding torque, so the use of a corresponding torque value of the wrench, but when the demolition torque is far greater than this torque, torque may reach more than 2 times. So the torque wrench is extremely likely to exceed the torque value, thereby directly damaging the wrench. Moreover, when the demolition time to start a large torque, but also a moment, so the measurement is not allowed.

一般情況下禁止使用扭矩扳手拆卸螺栓。主要是因為一個螺栓對應有相應的扭矩，所以選用一個相應的扭矩值的扳手，但是拆卸時候扭矩遠大于這個扭矩，瞬間扭矩可能達到2倍以上。這樣扭矩扳手極端可能超扭矩值，從而直接損壞了扳手。而且，拆卸時候啟動時扭矩很大，而且是瞬間的，因此測量是不準的。http://www.jrxshaft.com
