The outer wall of the hinge rod 331 is fixedly connected to the bottom of the locking rod 339. The outer wall of the locking rod 339 is provided with a locking groove 3310. The outer wall of the locking rod 339 is slidably connected to the inner wall of the sliding sleeve 4 338.

The locking rod 1 336 is away from the inner wall of the sliding sleeve 3 333 and is engaged with the wall of the clamping groove 1 6. The three groups of locking mechanisms 33 lock and fix the clamping sleeve 5 in multiple directions. After locking, the structure is stable and not easy to tilt.

[0042] The working principle of this embodiment is as follows: quick disassembly is performed through the snap disassembly mechanism 31, and the sliding sleeve 311 slides on the outer wall of the pipe 1. The sliding sleeve 311 drives the top block 314 to slide in the groove wall of the sliding groove 7, so that the top block 314 squeezes the outer wall of the pipe 22 to deform the clamping part between the pipe 22 and the pipe 11, so that the clamping part of the outer wall of the pipe 22 is separated from the clamping groove 28, so that the pipe 22 is completely disassembled. When the installation of the pipe 1 and the pipe 22 is completed and no disassembly is required, the hinge rod 331 is positioned through the positioning groove 312 to prevent the pipe 1 and the pipe 22 from rotating. At the same time, the positioning block 313 and the clamping groove 332 are pressed and fixed to prevent the sliding sleeve 311 from sliding.
