预制式扭力扳手的外壳用特质合金钢材料制造，有预置扭矩数值和发讯装置，当紧固件的拧紧力扭矩达到预置数值时，能自动发出讯号“嗒”的一声，同时伴有明显的手感震动，解除作用力后，扳手各相关零件自动复位。设备还具有扭力准确，性能稳定，调校方便，寿命长等特点，适用于螺纹紧固扭矩的准确装配和控制，是保证和提高产品质量的工具。
The shell of the prefabricated torque wrench is made of special alloy steel material and has a preset torque value and a sending device. When the tightening torque of the fastener reaches the preset value, it can automatically send a signal "click", accompanied by obvious hand vibration. After the force is released, all relevant parts of the wrench will automatically reset. The equipment also has the characteristics of accurate torque, stable performance, convenient adjustment and long service life. It is suitable for accurate assembly and control of thread tightening torque and is a tool to ensure and improve product quality.
预制式扭力扳手操作方法：
Operation method of prefabricated torque wrench:
1、要根据测量工件的要求，选取适中量程，所测扭力值不可小于扭力器在使用中量程的百分之二十，太大的量程不宜用于小扭力部品的加固，小量程的更不可以超量程使用。
1. First, according to the requirements of measuring workpiece, select a proper range. The measured torque value shall not be less than 20% of the range of the torsion device in use. Too large range is not suitable for the reinforcement of small torsion parts, and the small range can not be used beyond the range.
2、使用时，先将扳手方榫连接好辅助配件(如各类批嘴、套筒)，确保连接已经没问题。在加固扭力之前，设定好需要加固的力值，并锁好紧锁装置，调整好方向转换钮到加力的方向，然后在使用时先快速连续操作4-5次，使扳手内部组件上特殊润滑剂能充分润滑，使更准确，使用。
2. When using, first connect the square tenon of the wrench with auxiliary accessories (such as various types of nozzles and sockets) to ensure that the connection has no problem. Before reinforcing the torque, set the force value to be reinforced, lock the locking device, adjust the direction switch button to the direction of force application, and then quickly and continuously operate it for 4-5 times during use, so that the special lubricant on the internal components of the wrench can be fully lubricated and more accurate for use.
3、测量时，手要把握住把手的，沿垂直于扭力扳手壳体方向，慢慢地加力，直听到扭力扳手发出“塔”的声音，此时扭力扳手已到达预置扭力值，工件已加力完毕，然后应及时解除作用力，以免损坏另部件。在施力过程中，按照标准仪器操作规范，其垂直度偏差左右不应超过10度。其水平方向上下偏差不应超过3度，操作人员在使用过程中应保证其上下左右施力范围均不超过15度；
3. During measurement, hold the handle and slowly apply force in the direction perpendicular to the shell of the torque wrench until the "tower" sound of the torque wrench is heard. At this time, the torque wrench has reached the preset torque value and the workpiece has been applied with force. Then, release the force in time to avoid damaging other parts. In the process of applying force, according to the national standard instrument operation specification, the verticality deviation shall not exceed 10 degrees. The vertical deviation in the horizontal direction shall not exceed 3 degrees, and the operator shall ensure that the upper, lower, left and right force ranges do not exceed 15 degrees during use;
4、为了不使测量结果因水平和垂直方向上的偏差而产生影响，在测量时，应在加力把持端上施加一个垂直向下的稳定力值，然后再手动加点力，这样操作可以让读数值更准确。
4. In order to prevent the measurement results from being affected by the deviation in the horizontal and vertical directions, during the measurement, a vertical downward stable force value shall be applied to the force applying holding end, and then a point of force shall be manually added. This operation can make the reading value more accurate.
5、读数：如果是带表扭力仪器，直接读取指针所指示的数据为测量数据值即可；如果是套筒加副刻度指示器，应先读取主刻度上的刻度值，再加上副刻度或微分筒上的刻度值之和为测量数据值。
5. Reading: if it is a torsion instrument with a meter, directly read the data indicated by the pointer as the measured data value; In case of sleeve plus sub scale indicator, the scale value on the main scale shall be read first, and then the sum of the scale value on the sub scale or the differential cylinder shall be the measured data value.
6、预置式扭力扳手是测量工具，应轻拿轻放，不能代替榔头进行敲打等不正当行为，不用时请注意将扭力设为较小值，存放在干燥处。扭力扳手应用范围较广，在加固扭力时，相对来讲比较简单，只需要设定其要求扭力值便可进行操作。
6. The preset torque wrench is a measuring tool and should be handled with care. It can not replace the hammer for knocking and other improper acts. When not in use, please set the torque to a small value and store it in a dry place. The torque wrench has a wide range of applications. It is relatively simple to reinforce the torque. It can be operated only by setting the required torque value.
