Through the pull rope 5 with one end connected with the arc-shaped protruding part 2 and the other end connected with the forceps body control sleeve 3, the acting force towards the forceps body control sleeve 3 direction can be effectively applied to the arc-shaped protruding part 2 of the forceps sheet 16 through the pull rope 5 in the process that the forceps body control sleeve 3 moves from the extending position to the retracting position. The direction of the acting force and the electrode forceps body 1 in the closed state form an acute angle, so that two adjacent forceps pieces 16 can be effectively pulled to move back to back, and the electrode forceps body 1 is opened. And the pull rope 5 is fixedly connected with the outer wall of the end part of the forceps body control sleeve 3. The problem that the pulling rope 5 is knotted or the position interference is caused to the forceps piece 16 in the process that the forceps body control sleeve 3 is driven to stretch and retract can be effectively avoided.
