When the air pressure in the cavity 214 reaches a preset value, the air pressure switch is switched from a normally open state to a normally closed state to prohibit gas from passing. In another embodiment, the first air valve 23 is a solenoid valve controlled by the processing unit 50. When the air pressure sensing unit 40 senses that the air pressure in the cavity 214 reaches a predetermined value, the processing unit 50 The first gas valve is controlled to be closed to inhibit the passage of gas.

The socket 30 includes a metal ball 31 and a base 32. The metal ball 31 is spherical and includes an open end through which the second rod 212 is fixedly coupled. The upper portion of the metal ball 31 is provided with a plurality of vent holes around the open end to serve as an air inlet for inflation.
