扭力扳手使用注意事项：
Precautions for use of torque wrench:
1、人们在选择扭力扳手时，要根据螺栓或螺母的尺寸来选择开口尺寸的扭力扳手。如果扭力扳手的开口尺寸大于螺栓或螺母的尺寸，那在使用时，容易滑脱并损伤螺件的六角。如果扭力扳手的开口尺寸太小，那无法嵌入到螺栓或螺母中进行扭动。
1. When selecting torque wrenches, people should select torque wrenches with open size according to the size of bolts or nuts. If the opening size of the torque wrench is larger than the size of the bolt or nut, it is easy to slip and damage the hexagon of the bolt when it is used. If the opening size of the torque wrench is too small, it cannot be inserted into the bolt or nut for twisting.
2、人们在使用扭力扳手时，为防止扳手损坏和滑脱，应使拉力作用在开口较厚的一边，如此才能用上力。另外，人们子啊使用扭力扳手时，要注意开口不能出现 “八”字形，以免损坏螺母和扳手。
2. When people use torque wrenches, in order to prevent the wrench from damage and slipping, the tension should be applied to the side with the thicker opening, so that the force can be used. In addition, when people use torque wrenches, they should pay attention not to have an "eight" shaped opening to avoid damaging the nuts and wrenches.
3、扭力扳手是按人手的力量来设计的，人手力量越大，扭力扳手在旋转螺纹、螺母时的力量越大。如果人们遇到较紧的螺纹件，用扭力扳手也不能使其松动的话，切记不能用捶打工具锤击扳手，以免损坏扳手，人们可以适当调整扳手的用力方向，找到的发力点。另外，还要注意的是，除了套筒扳手能套装加力杆，其他扳手都不能套装加力杆，扭力扳手也不能。遇到无法拧动的螺纹紧固件，人民不能胡乱给扭力扳手加装加力杆，以防损坏扳手或螺纹连接件。
3. The torque wrench is designed according to the strength of the human hand. The greater the strength of the human hand, the greater the strength of the torque wrench when rotating the thread and nut. If people encounter tight threaded parts and cannot loosen them with a torque wrench, remember not to hammer the wrench with a hammer tool to avoid damage to the wrench. People can adjust the direction of force of the wrench properly and find the force generating point. In addition, it should also be noted that except for socket wrenches, no other wrenches can be equipped with torque rods, nor can torque wrenches. When encountering threaded fasteners that cannot be screwed, people shall not randomly add torque rods to torque wrenches to prevent damage to wrenches or threaded connectors.
4、扭力扳手一般都带有预设扭矩数值和声响的装置，当紧固件的拧紧扭矩达到预设数值时，扭力扳手能自动发出讯号“卡嗒”声，同时伴有明显的手感振动，这表示扭力扳手已经将紧固件松好。将扭力扳手从紧固件上取下后，扳手各相关零件能自动复位。
4. The torque wrench is generally equipped with a device with preset torque value and sound. When the tightening torque of the fastener reaches the preset value, the torque wrench can automatically send out a signal "click" sound, accompanied by obvious hand vibration, which means that the torque wrench has loosened the fastener. After the torque wrench is removed from the fastener, all relevant parts of the wrench can be reset automatically.
5、扭力扳手一般是用来旋转螺栓或螺帽的，扳转时应该使用拉力，推转扳手更容易发生危险。人们在使用时，一定要注意这点。另外，扭力扳手可以用来松紧螺栓，螺栓旋紧前应先将螺栓清洁并上润滑油。
5. The torque wrench is generally used to rotate the bolt or nut. The tension should be used when turning, and the push wrench is more likely to cause danger. People must pay attention to this when using it. In addition, the torque wrench can be used to loosen and tighten the bolts. Before tightening the bolts, they should be cleaned and lubricated.
6、人们在使用扭力扳手旋紧螺栓时，应均匀使力，不得利用冲击力。简单来说，是不要用锤击工具来锤击扳手，使其在短时间内获得冲击力，从而带动整只扳手旋转，使扳手将螺栓旋紧，这种做法容易损坏扳手。
6. When people use a torque wrench to tighten the bolts, they should apply the force evenly and should not use the impact force. To put it simply, do not use hammering tools to hammer the wrench, so that it can obtain impact force in a short period of time, so as to drive the whole wrench to rotate, so that the wrench can tighten the bolt, which is easy to damage the wrench.
7、如果长期不用扭力扳手，那人们把扭力扳手的调节标尺刻线退至扭矩小数值处，这样可以延长扳手的使用寿命。
7. If the torque wrench is not used for a long time, people should withdraw the adjusting scale scale of the torque wrench to the small value of torque, which can extend the service life of the wrench.
