AI Technical Summary
The existing car bumper sleeve and the threaded connection of the tow bar have poor stability and are difficult to lock effectively, which makes them prone to slippage during towing.
A threaded sleeve is installed inside the bumper support column, and a movable locking bracket is installed at its front end. The pull rod is locked by the cooperation of the locking block and the tension spring. The pull line is released by the rotation of the gear and the winding rod, ensuring that the pull rod does not slip under tension.
This improves the connection stability between the sleeve and the drawbar, prevents slippage during traction, and enhances the traction effect.
