The top rod 21 is connected to a cross rod 7, which is slidably connected to the insert pipe 5. The pipe body 3 is inserted into the insert pipe 5, and the cross rod 7 is inserted into the bayonet 2 of the pipe body 3. When assembling the compressor body 1 and the hose body 3, the top ring 13 and inner ring 19 can be pushed into the outer cover 4. The inner ring 19 can compress the return spring 18, and the top ring 13 can drive the crossbar 7 away from the bayonet 2. The hose body 3 can then be inserted into the insertion tube 5. After insertion, the top ring 13 and inner ring 19 can be released, and the return spring 18 can push the inner ring 19 to reset. The top ring 13 will also reset, and the top ring 13 can push the crossbar 7 again. The crossbar 7 can then be inserted into the bayonet 2, thus achieving quick assembly. When disassembling, simply push the top ring 13 and inner ring 19 in the opposite direction.

[0030] Reference Figure 2 As shown, an outer cover 4 is provided outside the inner tube 20. The diameter of the outer cover 4 is larger than the diameter of the inner tube 20, and the height of the outer cover 4 is the same as the height of the inner tube 20. A return spring 18 is provided inside the outer cover 4. The return spring 18 is sleeved on the inner tube 20 inside the outer cover 4. By placing the return spring 18 between the outer cover 4 and the inner tube 20, the return spring 18 can push the inner ring 19 on the inner tube 20. The return spring 18 can keep the inner ring 19 in a state of moving outward, thereby keeping the top ring 13 in a state of pushing the crossbar 7.

[0031] In this embodiment, refer to Figure 3 As shown, an inner ring 19 is sleeved between the outer cover 4 and the inner tube 20. The diameter of the inner ring 19 is smaller than the diameter of the outer cover 4. The inner ring 19 is slidably connected between the outer cover 4 and the inner tube 20. The inner ring 19 is located at the outer port of the outer cover 4 and is located on one side of the return spring 18. The inner ring 19 can slide along the inner tube 20 through the sleeve. When the inner ring 19 slides, it can drive the top ring 13 to slide, and the top ring 13 can drive the vertical seat 10 to slide.

[0032] Example 2:

A guide rod 17 is slidably connected inside the vertical groove 15. The guide rod 17 has the same shape as the vertical groove 15 and is slidably connected inside the corresponding vertical groove 15. The opening of the vertical groove 15 allows the guide rod 17 to slide within it. The connection between the guide rod 17 and the vertical groove 15 restricts the inner ring 19, preventing it from rotating and thus maintaining the same position for extension and retraction. An opening 23 is provided at the output end of the guide rod 17. The guide rod 17 is U-shaped, with a guide wheel 14 rotatably connected inside the opening 23. The guide wheel 14 rests in the vertical groove 15 of the inner tube 20. A linkage rod 16 is provided on one end face of the guide rod 17, which can rotate through the guide wheel 14. When the guide rod 17 slides in the vertical groove 15, the guide wheel 14 can reduce the friction between the guide rod 17 and the vertical groove 15. The linkage rod 16 is perpendicularly connected to the guide rod 17, and the linkage rod 16 and the guide rod 17 are T-shaped. The linkage rod 16 is connected to the inner ring 19, and the guide rod 17 can drive the inner ring 19 to connect.
