[0042] When the support rod 21 is shaken by force, the bottom plate 13 is driven to vibrate, and the bottom plate 13 squeezes the corresponding telescopic airbag 12 and the gas inside it, thereby reducing the vibration it is subjected to.

[0043] A fixing seat 14 is installed on the base 11, and a limiting groove 141 is provided in the fixing seat 14, and a limiting ball 211 is fixedly installed on the lower end of the support rod 21, and the limiting ball 211 is rotatably installed in the limiting groove 141, and an annular airbag 142 is installed in the limiting groove 141, and the annular airbag 142 is sleeved on the outer wall of the limiting ball 211, and a sealing ring 143 is installed in the limiting groove 141.

[0044] Among them, the limiting groove 141 limits the swing position of the limiting ball 211. When the support rod 21 swings, it drives the limiting ball 211 to swing, squeezing the annular airbag 142. The gas inside the annular airbag 142 resets the limiting ball 211. At the same time, the sealing ring 143 prevents the limiting ball 211 from falling off.

[0045] A mounting plate 22 is fixedly mounted on the upper end of the support rod 21 . A plurality of connection holes 221 are formed on the mounting plate 22 . The plurality of connection holes 221 are arranged at four corners of the mounting plate 22 .

[0046] Furthermore, the fitness equipment can be installed on the mounting plate 22 by passing matching bolts through the multiple connecting holes 221, making disassembly more convenient.

[0047] The shock absorbing mechanism 3 has one end that is rotatably connected to the outer wall of the support rod 21, and the other end that is rotatably connected to the base 11.

[0053] The working principle and use process of this utility model: please refer to Figure 1-4 , the base 11 is fixed to the ground by adsorbing the ground through multiple suction cups 111. When the support rod 21 is shaken by force, the bottom plate 13 is driven to vibrate, and the bottom plate 13 squeezes the corresponding telescopic airbag 12, squeezes the gas inside it, and thus reduces the vibration it is subjected to. The limiting groove 141 limits the swing position of the limiting ball 211. When the support rod 21 swings, it drives the limiting ball 211 to swing, squeezes the annular airbag 142, and the limiting ball 211 is reset by the gas inside the annular airbag 142. When the connecting rod 32 is pulled by force, the slider 332 squeezes the shock-absorbing spring 331, and at the same time, the shock-absorbing spring 331 resists the partition 312. The shock-absorbing spring 331 is compressed and rebounds by its own elasticity, driving the slider 332 to reset. When the connecting rod 32 is subjected to thrust, it drives the piston block 341 to press down, and the piston block 341 squeezes the air inside the piston cylinder 34, thereby reducing the thrust applied to the connecting rod 32.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
