The support rods 3 are installed to the bottom of the fixed ring 2 to provide fixing points for the universal wheel 4 installed at the bottom thereof. A universal wheel 4 is installed at the bottom of the support rod 3. The universal wheel 4 transmits the supporting force inside it through the ground to provide support for the entire device. When the entire device is pushed by an external force, the universal wheel 4 extends and rotates in the direction of the external force, thereby improving the mobility of the device. A control switch 9 is installed on the front of the fixed shell 1. When it is necessary to supplement the internal nitrogen of the fixed shell 1, the control switch 9 can be moved by external force.
