[0029] In this embodiment, the gas guide pipe 2 includes a bottom full sleeve 5, a rear half sleeve 6, a front half sleeve 8 and a U-shaped card seat 7. The rear half sleeve 6 is integrally formed and connected to the upper end of the bottom full sleeve 5. On the left and right sides of the outer surface of the rear half sleeve 6, U-shaped card seats 7 are integrally formed. On the left and right sides of the outer surface of the front half sleeve 8, clamping blocks 9 corresponding to the positions of the U-shaped card seats 7 are integrally formed. Two fixing members 10 are arranged in each of the two clamping blocks 9. The clamping blocks 9 are clamped and installed in the U-shaped card seats 7 through the two fixing members 10 to fixedly connect the front half sleeve 8 to the front end of the rear half sleeve 6. On the upper and lower sides of the inside of the two clamping blocks 9, sliding grooves 91 are arranged. On the front ends of the two clamping blocks 9, two guide grooves 92 communicating with the inside of the sliding grooves 91 are arranged. The fixing member 10 includes a sliding block 101. The sliding block 101 is slidably connected in the sliding groove 91. On the opposite ends of the two sliding blocks 101 on the same side, two springs 102 are fixedly installed. The springs 102 are fixedly connected to the inner wall of the sliding groove 91. One end of the sliding block 101 away from the spring 102 is fixedly connected with a plug rod 103. A guide rod 104 is fixedly installed at the front end of the sliding block 101, and the guide rod 104 is slidably connected in the guide groove 92. The plug rod 103 penetrates through the inner wall of the sliding groove 91 and extends to the outside of the clamping block 9. The clamping block 9 is fixedly connected to the U-shaped card seat 7 through the two plug rods 103.
[0030] Through the above scheme: Pull the guide rod 104 to make the sliding block 101 slide in the sliding groove 91, so as to retract the plug rod 103 into the sliding groove 91. Then align the clamping block 9 of the front half sleeve 8 with the U-shaped card seat 7 of the rear half sleeve 6. At this time, release the guide rod 104, and use the elastic force of the spring 102 to push the sliding block 101 in the fixing member 10 to reset in the sliding groove 91, so as to push the plug rod 103 out of the sliding groove 91 and clamp it in the U-shaped card seat 7, so that the U-shaped card seat 7 is fixedly connected to the clamping block 9, thereby fixedly connecting the rear half sleeve 6 and the front half sleeve 8 together. The structure is simple, the installation steps are simplified, and the professional skill requirements are reduced.
[0031] In this embodiment, the structures of the rear half sleeve 6 and the front half sleeve 8 are the same and jointly form a cavity cylinder with the same inner diameter as the bottom full sleeve 5.

During use, when connection is required, first, the intake pipe 4 is sleeved inside the guide pipe 2, and the lower end of the intake pipe 4 is located inside the bottom full sleeve 5. Then, the guide rod 104 is pulled to make the slider 101 slide in the chute 91, so that the plug rod 103 is retracted into the chute 91. Then, the clamping block 9 of the front half sleeve 8 is aligned with the U-shaped clamping seat 7 of the rear half sleeve 6. At this time, the guide rod 104 is released, and the elastic force of the spring 102 is used to push the slider 101 in the fixing member 10 to reset in the chute 91, so that the plug rod 103 is pushed out of the chute 91 and clamped in the U-shaped clamping seat 7, making the U-shaped clamping seat 7 and the clamping block 9 fixedly connected, thus fixedly connecting the rear half sleeve 6 and the front half sleeve 8 together.
