These products are large and heavy, requiring limited installation and operating space. Traditionally, electrical connectors are tightened by alternately rotating the guide pins, typically one or two turns, resulting in low production efficiency. Furthermore, the process can easily lead to locking between the guide pins and guide holes, causing rework and affecting product quality. This invention designs a device that allows for the synchronous tightening of the guide pins and guide holes in electrical connectors. Utility Model Content

The bearing end of the cover plate faces the bearing end of the housing, and the two are fastened using standard parts, but not yet fully tightened. The wrench is inserted into the housing through the inner hole in the middle of the gear until it reaches the bottom. After rotating the wrench, the flexibility of rotation is checked, and then the standard parts are tightened.

[0007] Preferably, the housing has a through hole at the center of the countersunk hole, and the cover plate has threaded through holes and rounded corners at its four corners.
