[0032] In the embodiment, the plurality of extension rods 41 are evenly distributed on the side of the sleeve 2 inner top wall and inner bottom wall opposite, the two ends of the return spring 42 are fixedly connected between the return spring 42 and the side of the movable plate 43 opposite, and the cross-sectional shape of the movable plate 43 is arc-shaped.
