[0022] In this embodiment, the limiting mechanism 4 includes a limiting wheel 41, and the limiting wheel 41 is fixed to the surface of the bidirectional screw 3. A plurality of limiting holes 42 are opened on the surface of the limiting wheel 41. A protrusion 43 is fixed on one side of the concave plate 2.
