Maintenance and management of electric torsional shear wrench:

由于電動扭剪扳手是高頻應用工具，為了提高測量精度，有必要定期校準和檢查工具，并配置滿足使用要求的電動扭剪扳手設備。 目前，電動扭剪扳手主要由檢定儀對電動扭剪扳手進行校準，檢定儀需要定期檢查。 由于校準環(huán)境是試驗室環(huán)境，因此與現(xiàn)場操作環(huán)境有很大的不同。 為了確保校準管理的有效性，有必要參考實際使用現(xiàn)場進行管理，并且要求誤差不受使用場合的影響。 使用前要注意檢查電動扭剪扳手的準確性，并根據(jù)使用頻率調整校準和維護的頻率。 通常每年不少于一次，利用維護管理手段保證電動扭剪扳手的準確性。

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、 用扳手內套筒完全插進螺栓尾部梅花頭部分，同時向前推動扳手，內套筒后退，使外套筒完全套住螺母，若不能完全套住螺母請左右轉動扳手并向前用力。

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、 扣動扳手開關，使其旋轉。

2. Turn the wrench to turn the switch.

3、 擰斷梅花頭，緊固結束，同時扣動板機彈出梅花頭。

3. Unscrew the plum blossom head, tighten it, and pull the trigger to pop up the plum blossom head at the same time.

二，套筒更換：

2、 Sleeve replacement:

1、 把扳手護罩擰下來，把外套筒、內套筒及內套筒彈簧取出。

1. Unscrew the wrench cover and take out the outer sleeve, inner sleeve and inner sleeve spring.

2、 先裝上內套筒的彈簧及所換內套筒，然后裝上相應的外套筒，前殼體凸起部與外套筒凹下部相連接，并把護罩擰上

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
