电动扭剪扳手的维护管理：
Maintenance and management of electric torsional shear wrench:
由于电动扭剪扳手是高频应用工具，为了提高测量精度，有必要定期校准和检查工具，并配置满足使用要求的电动扭剪扳手设备。 目前，电动扭剪扳手主要由检定仪对电动扭剪扳手进行校准，检定仪需要定期检查。 由于校准环境是试验室环境，因此与现场操作环境有很大的不同。 为了确保校准管理的有效性，有必要参考实际使用现场进行管理，并且要求误差不受使用场合的影响。 使用前要注意检查电动扭剪扳手的准确性，并根据使用频率调整校准和维护的频率。 通常每年不少于一次，利用维护管理手段保证电动扭剪扳手的准确性。
As the electric torsional shear wrench is a high-frequency application tool, in order to improve the measurement accuracy, it is necessary to calibrate and check the tool regularly, and configure the electric torsional shear wrench equipment that meets the use requirements. At present, the electric torsional shear wrench is mainly calibrated by the calibrator, and the calibrator needs to be checked regularly. Since the calibration environment is a laboratory environment, it is very different from the field operation environment. In order to ensure the effectiveness of calibration management, it is necessary to refer to the actual use site for management, and the error is not affected by the use occasion. Before use, pay attention to check the accuracy of the electric torsion shear wrench, and adjust the calibration and maintenance frequency according to the use frequency. Usually at least once a year, use maintenance and management means to ensure the accuracy of electric torsion shear wrench.
一，使用方法：
1、 Usage:
1、 用扳手内套筒完全插进螺栓尾部梅花头部分，同时向前推动扳手，内套筒后退，使外套筒完全套住螺母，若不能完全套住螺母请左右转动扳手并向前用力。
1. Insert the inner sleeve of the wrench completely into the box head at the tail of the bolt, and push the wrench forward at the same time. The inner sleeve retreats to make the outer sleeve completely cover the nut. If the nut cannot be completely covered, please turn the wrench left and right and force forward.
2、 扣动扳手开关，使其旋转。
2. Turn the wrench to turn the switch.
3、 拧断梅花头，紧固结束，同时扣动板机弹出梅花头。
3. Unscrew the plum blossom head, tighten it, and pull the trigger to pop up the plum blossom head at the same time.
二，套筒更换：
2、 Sleeve replacement:
1、 把扳手护罩拧下来，把外套筒、内套筒及内套筒弹簧取出。
1. Unscrew the wrench cover and take out the outer sleeve, inner sleeve and inner sleeve spring.
2、 先装上内套筒的弹簧及所换内套筒，然后装上相应的外套筒，前壳体凸起部与外套筒凹下部相连接，并把护罩拧上
2. First install the spring of the inner sleeve and the replaced inner sleeve, and then install the corresponding outer sleeve. The convex part of the front shell is connected with the concave lower part of the outer sleeve, and screw on the shield
