[0029] The side wall of the positioning column 3 is sleeved with a connecting piece 12, and the top end surface of the connecting piece 12 is fixedly connected with a magnetic piece 14. The side wall of the positioning column 3 is fixedly connected with a magnetic piece 3 13, and the two adjacent surfaces of the magnetic piece 3 13 and the magnetic piece 4 14 are of the same polarity.

[0030] When the hoop tube needs to be removed, the connecting piece 12 is pulled upward, so that the connecting piece 12 moves upward with the two sets of positioning columns 3, and the positioning columns 3 drive the push block 4 and the connecting rope 9 to move upward, and the connecting rope 9 pulls the clamping block 8 to move into the upper hoop tube 1, thereby canceling the clamping connection between the upper hoop tube 1 and the lower hoop tube 2, and then the connecting piece 12 is pulled upward to remove the upper hoop tube 1 from the lower hoop tube 2, thereby realizing a set of continuous disassembly actions, simplifying the operation process of disassembling the hoop tube and improving the operation efficiency.
