The wiring head 1 is installed on the electrode seat 2, and the lower end of the electrode seat 2 is sleeved with a protective shell 3. The center of the protective shell 3 is movably connected with the control structure 5. The protective end sleeve 4 is fixed to the lower end of the protective shell 3 and is sleeved with the control structure 5. By installing the wiring head 1 and the electrode seat 2, the wiring head 1 and the electrode seat 2 are connected, which can provide electric energy for the control structure 5, thereby helping the coagulation work. The protective shell 3 is used for protection purposes, and the protective end sleeve 4 is fixed at the lower end of the protective shell 3, which is convenient for the protective sleeve connection of the control structure 5, thereby achieving the purpose of insulation protection;

[0021] The control structure 5 includes a movable frame 6, an articulated frame 7, a pushing block 8, a cooperative frame 9 and a pushing rod 10. The lower end of the movable frame 6 is elastically hinged with an articulated frame 7, and the lower end of the articulated frame 7 is hinged with a pushing block 8. The lower end of the pushing block 8 is fixedly connected to the pushing rod 10 through the cooperative frame 9. By installing the control structure 5, the movable frame 6 in the control structure 5 is hinged to the protective shell 3. By pressing, the articulated frame 7 can be driven to move, and the articulated frame 7 is hinged to the pushing block 8, which can push the cooperative frame 9 and the pushing rod 10 to move. When the pushing rod 10 moves, the docking control rod 13 can be pressed by the articulated bracket 11, so that the docking control rod 13 moves around the articulated guide block 12 to help the clamping work, and the structure is simple and can respond to control in the first time.

[0022] The lower end of the push rod 10 is fixedly connected to an articulated bracket 11 , the lower end of the articulated bracket 11 is hingedly provided with a docking regulating rod 13 , the docking regulating rod 13 is fixed to an articulated guide block 12 , and the bottom end of the articulated guide block 12 is fixedly connected to a tweezer head 14 .
