However, there is an electrical connection part between the gripper and the truss manipulator. After each replacement, the connection part between the gripper and the truss manipulator needs to be debugged again, which makes the replacement process complicated and affects the working efficiency of the truss manipulator.

[0024] After the end portion 304 of the clamping jaw is worn out by use, the second threaded rod 302 is rotated, and the second threaded rod 302 is threadedly connected to the connecting frame 301. The second threaded rod 302 moves while rotating, driving the sleeve plate 305 to move. One end of the sleeve plate 305 is slidably connected to the first slide rail 306 to fix the movement path of the first slide rail 306.
