[0026] When the driving component is started, the moving column 61 is driven by the driving component to move to a suitable position, so that the fixed plate 63 is attached to one side of the yoke, and by rotating the rotating block 65, the second threaded rod 64 is rotated by the rotating block 65, and the driving block 66 is moved in the threaded direction by the rotation of the second threaded rod 64, and since the driving block 66 is connected with the moving plate 67, the moving plate 67 will also move.
