AI Technical Summary
The existing cable laying device cannot lock the cable, causing the cable to fall as the length of the cable laid out increases, resulting in an excessively long laying length.
A servo electric cylinder is used to drive the movable clamping block to cooperate with the fixed clamping block. The extension end of the servo electric cylinder drives the movable clamping block to approach the fixed clamping block, thereby locking the cable to prevent it from falling.
It enables timely locking of the cable, preventing it from falling due to its own weight and ensuring the stability of the cable length.
