双枪头同步定扭螺栓锁附装置
By using a dual-head synchronous torque-locking bolt device, the electric screwdriver's two heads can rotate synchronously in the same direction through the meshing structure of the driving gear and the driven gear. This solves the problem of low tightening efficiency of a single-head electric screwdriver and improves assembly efficiency and applicability.

AI Technical Summary
Existing electric screwdrivers can only operate with one head, which means that the tightness of two bolts depends on the operator's feel and experience, affecting assembly efficiency, especially when assembling large batches.
A dual-head synchronous torque bolt tightening device is designed, which adopts a drive gear and driven gear meshing structure to achieve synchronous and unidirectional rotation of the two heads. It is suitable for tightening bolts of different specifications through quick-release ball screw structure and aluminum alloy shell.
It achieves consistent tightening of the two bolts, improves assembly efficiency, adapts to the needs of bolts of different specifications, and features a compact, lightweight structure that is easy to operate.
