Four supporting wheels 14 are rotatably arranged on the side of the main rod 11, a pull rod groove 15 is provided on the main rod 11, a pull rod 6 is slidably arranged in the pull rod groove 15, one end of the pull rod 6 passes through the main rod 11 and is installed with a pull ring, a pressurizing chamber 33 is arranged inside the pressurizing mechanism 3, a piston 34 is slidably arranged in the pressurizing chamber 33, the inside of the pressurizing chamber 33 is connected to the filtering mechanism 4 through an air inlet pipe 32, and the inside of the pressurizing chamber 33 is connected to the inside of the gas tank 2 through an air outlet pipe 31.

[0021] A side rod is arranged on the side of the main rod 11 , and one end of the side rod is connected to the main rod 11 , and the other end is hinged with a steering rod 13 , and the support wheel 14 is rotatably arranged on the steering rod 13 .

[0022] A support rod 22 is fixedly connected to the bottom of the gas tank 2, and a support groove 12 is opened on the frame 1. One end of the support rod 22 is connected to the outer wall of the gas tank 2, and the other end is slidably connected to the support groove 12.

[0023] A spring 23 is sleeved on the outside of the support rod 22 , and an annular convex block is arranged on the outside of the support rod 22 . One end of the spring 23 contacts the annular convex block on the outside of the support rod 22 , and the other end contacts the top of the frame 1 .

[0024] A slider 62 is slidably arranged in the pull rod groove 15, a limiting groove 16 is provided on the groove wall of the pull rod groove 15, a limiting block 63 is arranged on the side of the slider 62, the limiting block 63 is slidably arranged in the limiting groove 16, and a rotating block 61 is slidably arranged in the pull rod groove 15, one end of the rotating block 61 is rotatably connected to the slider 62, and the other end is hinged to one end of the pull rod 6 located in the pull rod groove 15.

[0025] A motor 37 is installed on the top of the support platform 5, and the output end of the motor 37 is connected to a turntable 36 through a transmission shaft. The pressurizing chamber 33 is provided with an opening at one end close to the motor, and a connecting rod 35 is provided at the opening. One end of the connecting rod 35 is hinged to the piston 34, and the other end is rotatably connected to a position off-center on one side of the turntable 36.
