As an embodiment of the present invention: a connecting ring III 306 is fixed inside the fixed sleeve 303, a rotating groove 307 is formed in the connecting ring III 306, a limiting clamping groove 308 is formed at the lower end of the rotating groove 307, a connecting hole 311 is formed in the surface of the upper end of the connecting ring III 306, the locking rod 304 penetrates through the connecting hole 311, a return spring II 309 is fixed at the bottom of the fixed sleeve 303, the upper end of the return spring II 309 is movably connected to the locking rod 304, a limiting clamping block 310 is arranged on the surface of the lower end of the locking rod 304, and a rotating disc II 305 is fixed at the upper end of the locking rod 304, when the locking rod 304 needs to be pulled upwards in actual use, the rotating disc II 305 is held to pull the locking rod 304 upwards in use, when the locking rod 304 cannot be pulled upwards continuously, the rotating disc II 305 rotates forty-five degrees clockwise, the limiting clamping block 310 on the locking rod 304 rotates along the rotating groove 307, then the rotating disc II 305 is loosened, and the locking rod 304 moves downwards under the action of the return spring I220, the limiting fixture block 310 at this time is clamped into the limiting fixture groove 308, so that the locking rod 304 is limited.

As an embodiment of the present invention: when the electric push rod 407 is actually used, firstly the silica gel air bag column 405 is inflated to expand the silica gel air bag column 405, the power supply of the electric push rod 407 is switched on, the output end of the electric push rod 407 moves forwards, at the moment, the silica gel air bag column 405 moves forwards under the action of the electric push rod 407, when the output end of the electric push rod 407 moves backwards, the silica gel air bag column 405 moves backwards under the action of the connecting spring 413, thus, the silica gel air bag column 405 slides back and forth circularly, thereby performing friction massage on the navel part of the child.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
