And because the speed of filling the nitrogen is greater than the exhaust speed of the diffusion rod 9, the first spring 14 is always in an elongated state when the diffusion rod 9 inflates the capsule 4.

Referring to fig. 1, since the exhaust holes 93 of the extension rod 92 are spaced apart by a small distance, i.e., have a large number, the nitrogen gas in the extension rod 92 is dispersed and thus introduced into the capsule 4 more softly.

Before inflation, the extension rod 92 is sleeved on the fixing rod 91; with the filling of the nitrogen gas, the air pressure in the fixing rod 91 rises, the nitrogen gas pushes the extension rod 92 to slide along the sliding groove 911, the diffusion rod 9 extends, the exhaust holes 93 are exposed one by one, and the nitrogen gas enters the capsule 4 through the exhaust holes 93.

The capsule 4 is gradually expanded by the nitrogen, when the air inlet valve 7 is not filled with the nitrogen, the first spring 14 pulls the extension rod 92 to be sleeved on the fixing rod 91, and the diffusion rod 9 is shortened.

As the oil feed valve 10 is continuously filled and drained with oil, the capsule 4 is repeatedly contracted and expanded, and the capsule 4 does not touch the diffusion rod 9.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
