The platform 782 moves upwards to compress the reinforcing spring 79. When the insulating rod stops rotating, under the reaction force of the reinforcing spring 79, the lower end of the upper brake sliding platform 782 is closely attached to the upper end of the lower braking sliding platform 781. Therefore, the main chassis 1 is integrated with the first drive shaft 71 and the insulating rod to prevent the main chassis 1 from being affected by its own weight in the process of lifting the main chassis 1 through the insulating rod. The bottom rotates relative to the insulating rod and the first drive shaft 71 to keep the left pliers 3 and the right pliers 4 stable, so that the external leads can be positioned quickly and accurately. When the external lead wire needs to be clamped, in the process of rotating the insulating rod, since the main chassis 1 cannot rotate under the obstruction of the external lead wire, the first drive shaft 71 can be rotated so that the right pliers body 4 moves to the left to close Jaws, and the lower brake slide 781 moves downward to leave the upper brake slide 782, thereby breaking away from the braking state.
