扭力扳手使用方法：

Usage of torque wrench:

1、选用合适量程的扭力扳手。力扳手的使用中，要根据测量工件的要求，选取适中量程扭力扳手，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，小量程的扭力器更不可以超量程使用。

1. Select the appropriate range of torque wrench. In the use of the torque wrench, first of all, according to the requirements of the measuring workpiece, select a torque wrench with moderate range. The measured torque value shall not be less than 20% of the range of the torque device in use. Too large range shall not be used for the reinforcement of small torque parts, and the small range torque device shall not be used beyond the range.

2、根据工件所需扭矩值要求，确定预设扭矩值。预设扭矩值时，将扳手手柄上的锁定环下拉，同时转动手柄，调节标尺主刻度线和微分刻度线数值所需扭矩值。调节好后，松开锁定环，手柄自动锁定。

2. Determine the preset torque value according to the required torque value of the workpiece. When preset the torque value, pull down the locking ring on the wrench handle, turn the handle at the same time, and adjust the main scale line and differential scale line of the scale to the required torque value. After adjustment, release the locking ring and the handle will lock automatically.

3、确认扭力扳手与固定件连接可靠并已锁定、用扭力扳手时，先将扳手方榫连接好辅助配件(如套筒，各类批嘴)，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5-6次，使扳手内部组件上特殊润滑剂能充分润滑，使扭力扳手更精确，持久使用。

3. Confirm that the connection between the torque wrench and the fixed parts is reliable and locked. When using the torque wrench, first connect the square tenon of the wrench to the auxiliary accessories (such as socket and various nozzles) to ensure that the connection is no problem. Before strengthening the torque, set the force value to be strengthened, lock the locking device, adjust the direction change button to the direction of the force application, and then operate the torque wrench for 5-6 times in a quick and continuous manner, so that the special lubricant on the internal components of the wrench can be fully lubricated, making the torque wrench more accurate and durable.
