The multiple sealing rings 17 on the air intake pipe 7 are respectively engaged in the sealing groove 13. The threaded barrel 14 is rotated, and the outer wall of the threaded barrel 14 rotates in the threaded groove 18. When the inner wall of the inclined groove 15 fits with one side of the elastic metal ring 16, the threaded barrel 14 is rotated for a distance so that the threaded barrel 14 squeezes the elastic metal ring 16. The inner wall of the elastic metal ring 16 fixes the air supply pipe 9 in the air intake pipe 7. The structural design of the sealing groove 13 and the sealing ring 17 can form a labyrinth seal between the air supply pipe 9 and the air intake pipe 7, thereby improving the seal between the air supply pipe 9 and the air intake pipe 7 and preventing the stored gas in the gas tank body 12 from leaking after long-term use.

[0021] like Figure 1 and Figure 2As shown, the lower end of the gas tank body 12 is fixedly connected to a support frame 10, and one side of the outer wall of the support frame 10 is fixedly connected to one side of the protective shell 1.
