When it is necessary to repair the measuring instrument 29, the rotating wheel 33 is first rotated. The rotation of the rotating wheel 33 drives the threaded rod 32 to rotate. Since the threads on the surface of the threaded rod 32 are mutually reverse threads with the rotating wheel 33 as the center, when the rotating wheel 33 drives the threaded rod 32 to rotate, the two movable plates 35 threadedly connected on its surface will move in the direction away from each other on the surface of the sliding rod 34. The two movable plates 35 move in the direction away from each other on the surface of the sliding rod 34, driving the two connecting rods 36 to move in the direction away from each other. The two connecting rods 36 move in the direction away from each other and drive the two clamping bars 37 to move in the direction away from each other. The two clamping bars 37 move in the direction away from each other, and the clamping limit of the measuring instrument 29 is released.
