专用套筒分为内套筒、外套筒，施工时，内套筒抓住螺栓杆梅花头，外套筒紧固螺栓螺帽，反向紧固。到达扭矩后，内套筒把梅花头扭断，这时抽出套筒，扣动扳机弹出梅花头。

Special sleeves are divided into inner sleeves and outer sleeves. During construction, the inner sleeve grabs the plum blossom head of the bolt rod, and the outer sleeve tightens the bolt and nut in the opposite direction. After reaching the maximum torque, the inner sleeve twists and breaks the plum blossom head. At this time, the sleeve is pulled out and the trigger is pulled to pop out the plum blossom head.

扭剪型77779193永利首页网址在工作之前，要把套筒头对准螺栓梅花头合理地插进，插到底部后再开始工作。

Before starting work, the torque type electric wrench should align the socket head with the bolt head and insert it in a reasonable manner. After inserting it to the bottom, it can start working.

一般地：当紧固螺栓到相当次数时，内套筒会因磨损而造成弹不出梅花头，这时更换套筒即可重新使用。

Generally, when the bolts are tightened a considerable number of times, the inner sleeve will wear and tear, causing it to not bounce out of the plum blossom head. At this time, the sleeve can be replaced and reused.

若在施工过程中，当梅花头弹不出时，可能的原因有以下几种：

If during the construction process, the plum blossom head cannot bounce out, there are several possible reasons:

①螺栓材质有问题。当螺栓发软时，会造成梅花头弹不出来。

① There is an issue with the bolt material. When the bolt becomes soft, it will cause the plum blossom head to not pop out.

②施工不正确。若插入螺栓时不顺利或者有倾斜角度，就可能造成梅花头弹不出来。

② Incorrect construction. If the bolt insertion is not smooth or there is an inclination angle, it may cause the plum blossom head to not pop out.

③套筒出现问题。请检查套筒是否已经磨损过度，或其他情况，也会造成梅花头弹不出来。

③ There is a problem with the sleeve. Please check if the sleeve has worn excessively or if there are other conditions that may cause the plum blossom head to not pop out.
