The arc-shaped hole 48 provides guidance and limiting for the connecting rod 49, so as to prevent the U-shaped clamp plate 46 from deviating or shaking during sliding. After the connecting line is connected to the power socket 7, the second spring 45 starts to recover deformation, releases the elastic potential energy, and pushes the sliding block 44 to drive the U-shaped clamp plate to move towards the connecting line. The rubber U-shaped pad 47 on the inner wall of the U-shaped clamp plate 46 tightly adheres to the surface of the connecting line by virtue of good elasticity and flexibility, increases the contact area, provides stronger friction, firmly clamps the connecting line, and prevents the connecting line from falling off from the power socket 7 due to accidental pulling and shaking.
