A lead screw 403 is provided on one side of the micro motor 402. A moving sleeve 404 is sleeved outside the lead screw 403. The moving sleeve 404 is slidably connected to the mounting frame 401, and a clamping plate 405 is connected above the outside of the moving sleeve 404. The mounting frame 401 and the clamping plate 405 are evenly distributed in an array of three. The clamping plate 405 is slidably connected to the bearing plate 3, and the clamping plate 405 is arc-shaped; by means of the three micro motors 402, it is convenient to drive the rotation of the three lead screws 403 inside the three mounting frames 401.
