[0024] Working principle:

[0025] When in use, firstly, the assembly mechanism 2 needs to be installed on the main pipe body 1. The separated assembly mechanism 2 only needs to be wrapped around the main pipe body 1. Then, the assembly mechanism 2 is locked to fix the assembly mechanism 2 on the main pipe body 1. Then, the three groups of adjustment mechanisms 3 on the assembly mechanism 2 are extended and pressed against the ground. Then, the position of each group of adjustment mechanisms 3 is adjusted by rotating the adjustment ring 35 to adapt to different ground heights, thereby firmly supporting the main pipe body 1.

[0026] Before installing the assembly mechanism 2 on the main pipe, it is necessary to ensure that the assembly mechanism 2 is in a separated state, then wrap the main shell 21 and the sub-shell 24 on the main pipe body 1, then move the buckle 25 on the main shell 21 close to the buckle 28, and slide the buckle 25 into the buckle 28, thereby locking the position of the main shell 21 and the sub-shell 24, and then install the assembly mechanism 2 on the main pipe body 1, and fixing rings 22 are provided on the upper and lower parts of the main shell 21 and the sub-shell 24, and the anti-slip ring 23 on the fixing ring 22 is attached to the main pipe body 1 under the drive of the fixing ring 22, and the friction between the fixing ring 22 and the main pipe body 1 is increased through the deformation of the anti-slip ring 23, thereby preventing the assembly mechanism 2 from slipping off the main pipe body 1.

[0027] When it is necessary to remove the assembly mechanism 2 from the main pipe body 1, it is only necessary to press the buckle 25 to make the buckle 25 slide out of the groove in the buckle ring 28 to release the lock between the main shell 21 and the auxiliary shell 24, and then rotate the shells along the hinge 27 to remove the shells from the main pipe body 1 and put them in a separated state.

[0028] After the assembly mechanism 2 is installed on the main pipe body 1, the adjustment mechanism 3 can be extended along the fixing seat 26, and then the adjusting ring 35 can be rotated so that the block 37 is between the protrusions 36. After the block 37 is free from the restriction of the protrusion 36, the spring piece 38 on the top of the block 37 can release the elastic potential energy, thereby pushing the protrusion 36 to slide in the direction close to the adjusting ring 35. During the sliding process, the protrusion 36 slides out of the limit groove 32, thereby releasing the lock on the sliding column 31. Then, the sliding sleeve 33 is slid in the direction away from the sliding column 31, and the supporting foot 4 at the bottom of the sliding sleeve 33 is pressed against the ground.

[0029] After the supporting foot 4 is against the ground, the adjusting ring 35 is rotated again, and the sliding groove 34 on the sliding sleeve 33 is used to limit the sliding position of the adjusting ring 35, so that the protrusion 36 slides to the block 37 and forces the block 37 to slide into the limiting groove 32, thereby locking the position of the sliding column 31 again, and the spring piece 38 is synchronously compressed during the sliding process of the block 37, so that the spring piece 38 accumulates elastic potential energy.
