扭力bai扳手有两种调节扭力的设计，一种du是外调式，不用带任何工具，zhi也不用拆dao卸机器就可以直接在机器上调节扭力。一种是内调式，需要工具搭配调节扭力。例如内调式的，要六角扳手拧开头壳前端的螺丝，用手转动主轴，转到主轴出现内六角螺丝时停止，用扳手扭动这颗螺丝就可以了。扭力扳手产从方式来bai分有“咔嗒式报警扳手”du，使用zhi方法是在扳手上调整到你需要的dao扭矩值，用扳手锁螺栓的时候当到达扭矩值就会发出咔嗒声。这时要马上松开螺栓，以免过扭。

　　There are two kinds of torque adjustment design for the torque Bai wrench. One is the external adjustment type, which can be directly adjusted on the machine without taking any tools or dismantling the machine. One is internal adjustment, which requires tools to adjust the torque. For example, for the internal adjustment type, the screw at the front end of the shell should be turned with a hexagon wrench. Turn the spindle to the spindle and stop when the hexagon screw appears. Turn the wrench to turn the screw. Torque wrench production from the way, Bai has "click alarm wrench" Du, the use of Zhi method is to adjust the wrench to the Dao torque value you need, when you lock the bolt with the wrench, when the torque value is reached, there will be a click sound. At this time, loosen the bolt immediately to avoid over twisting.

　　“折弯式扭矩扳手”。锁螺栓的时候当到达预设的扭矩值，扳手前端就会折弯，显示到达已到达扭矩值。

　　"Bending torque wrench". When the bolt is locked, when the preset torque value is reached, the front end of the wrench will be bent, indicating that the torque value has been reached.

　　“自滑转扭矩扳手”，当到达预设扭矩值的时候前端就会自动滑转，再也加不上力，永远不会过扭。

　　"Self sliding torque wrench", when reaching the preset torque value, the front end will automatically slide, no more force will be added, and it will never be over twisted.

　　简单说，扭矩扳手就是为了精确锁定螺栓。一般都是先预设锁螺栓的扭矩值，然后当扳手报警的时候就表示锁紧螺栓的扭矩值达到了。防止锁螺栓的时候扭力过大引起断裂，或者扭力过小螺栓容易松动。

　　Simply put, the torque wrench is to precisely lock the bolt. Generally, the torque value of the locking bolt is preset first, and then when the wrench alarms, the torque value of the locking bolt is reached. To prevent the bolt from breaking when the torque is too large, or the bolt is easy to loose when the torque is too small.
