[0034] Reference Figure 1 The movable plate 6 is arranged at the bottom of the first spring 3, and the first spring 3 can be squeezed by the movable plate 6. The top of the movable plate 6 is fixedly connected with a gasket 15, and the gasket 15 is arranged in the first spring 3. The gasket 15 can protect the buffer column 14.
