扭力bai扳手有兩種調節(jié)扭力的設計，一種du是外調式，不用帶明顯工具，zhi也不用拆dao卸機器就可以直接在機器上調節(jié)扭力。一種是內調式，需要工具搭配調節(jié)扭力。例如內調式的，要六角扳手擰開頭殼前端的螺絲，用手轉動主軸，轉到主軸出現內六角螺絲時停止，用扳手扭動這顆螺絲就可以了。扭力扳手產從方式來bai分有“咔嗒式報警扳手”du，使用zhi方法是在扳手上調整到你需要的dao扭矩值，用扳手鎖螺栓的時候當到達扭矩值就會發(fā)出咔嗒聲。這時要馬上松開螺栓，以免過扭。
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.
“折彎式扭矩扳手”。鎖螺栓的時候當到達預設的扭矩值，扳手前端就會折彎，顯示到達已到達扭矩值。
"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.
“自滑轉扭矩扳手”，當到達預設扭矩值的時候前端就會自動滑轉，再也加不上力，永遠不會過扭。
"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.
簡單說，扭矩扳手就是為了準確鎖定螺栓。一般都是先預設鎖螺栓的扭矩值，然后當扳手報警的時候就表示鎖緊螺栓的扭矩值達到了。防止鎖螺栓的時候扭力過大引起斷裂，或者扭力過小螺栓容易松動。
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.
