AI Technical Summary
Technical Problem
In the existing technology, tightening the connector screws one by one can easily cause the connector to tilt, the screws to twist laterally, and it is impossible to screw them in vertically and smoothly, which is cumbersome and inefficient.
Method used
A synchronous differential fastening device for connector screws was designed. The device drives a transmission gear set through a power input structure to achieve synchronous fastening of two screws. The transmission gear set and the coupling head are used to rotate the screws synchronously.
Benefits of technology
It enables rapid and synchronous tightening of connector screws, avoids screw tilting and twisting problems, improves operating efficiency by 60%, and reduces material waste.

Abstract
本实用新型公开了一种连接器螺钉同步差速紧固装置，包括装置外壳、动力输入结构以及传动齿轮组；装置外壳设置有部分延伸至装置外壳外部的第二传动轴和第五传动轴，且第二传动轴和第五传动轴延伸至装置外壳外部的一端的端部设置耦合头；动力输入结构驱动传动齿轮组运动，且动力输入结构通过所述传动齿轮组驱动所述第二传动轴和所述第五传动轴同步转动以同步旋紧连接器的两个螺钉。本实用新型的装置通过动力输入结构驱动装置内部传动齿轮组转动以驱动两根耦合头的轴杆同步转动，实现连接器两个紧固螺钉快速同步紧固，解决了螺钉逐个紧固时造成连接器倾斜，导致螺钉侧向扭曲，无法垂直顺畅旋入的问题。
