[0030] As Figure 2 And Figure 3 Damping assembly 9 includes inner rod 901 and outer rod 902 arranged between fixed plate 2, inner rod 901 and outer rod 902 are movably sleeved, one end of inner rod 901 is fixedly provided with second spring 903, can provide buffering for rubber air bag 1, improve buffering effect.

[0031] Secondly, the damping assembly 9 further comprises a sleeve ring 904 fixedly sleeved with one end of the inner rod 901, the outer wall of the sleeve ring 904 is hingedly provided with a plurality of connecting rods 905, one end of the connecting rod 905 is hingedly provided with a hinge seat 906, which is convenient for driving the hinge seat 906 to move simultaneously, one end of the outer rod 902 is fixedly sleeved with a fixed sleeve ring 907, the outer wall of the fixed sleeve ring 907 is fixedly provided with a plurality of guide frames 908, the inner part of the guide frame 908 is fixedly provided with a guide rod 909, the guide rod 909 is movably sleeved with a sleeve block 910, which can ensure the stable movement of the sleeve block 910, the sleeve block 910 is fixedly connected with the hinge seat 906, which is convenient for driving the sleeve block 910 to move simultaneously, the outer wall of the sleeve block 910 is sleeved with a third spring 911, one end of the third spring 911 is fixedly connected with the guide frame 908, the other end of the third spring 911 is fixedly connected with the sleeve block 910, which provides buffer for the rubber air bag 1 and improves the buffer effect.
