A connecting component 2 is jointly arranged at the top end of the straight tube body 1 and the bottom end of the curved tube body 4. The connecting component 2 facilitates the disassembly of the sleeve structure.

[0034] The connecting component 2 includes five connecting grooves 24. The five connecting grooves 24 are all opened at the top end of the straight tube body 1. The five connecting grooves 24 are arranged in a rectangular array. The inner walls of the five connecting grooves 24 are all movably inserted with connecting rods 21.

[0035] The five connecting rods 21 are arranged in a circular array, and the outer surface shape of the connecting rods 21 is the same as the inner wall shape of the connecting grooves 24, which is more convenient for inserting the connecting rods 21 into the connecting grooves 24 better.

[0036] The top ends of the five connecting rods 21 are all fixedly connected to the bottom end of the curved tube body 4. Pulling out the connecting rods 21 from the corresponding connecting grooves 24 realizes the separation of the straight tube body 1 and the curved tube body 4.

[0037] Five through grooves 23 are opened on the outer surface of the straight tube body 1, and first connection holes 22 are opened on the inner walls of one sides of the five through grooves 23. Second connection holes 26 for cooperating with the first connection holes 22 are opened at one ends of the five connecting rods 21. The inner walls of the corresponding first connection holes 22 and second connection holes 26 are jointly threadedly connected with connection bolts 25. Screwing out the connection bolts 25 from the first connection holes 22 and the second connection holes 26 realizes the rapid disassembly of the sleeve structure.

[0038] The inner walls of the five first connection holes 22 and the five second connection holes 26 are all threaded. The threads on the outer surface of the connection bolts 25 are all matched with the inner wall threads of the first connection holes 22 and the second connection holes 26, which is convenient for the connection bolts 25 to cooperate with the first connection holes 22 and the second connection holes 26.

[0039] The five through grooves 23 are arranged in a circular array, and the inner wall diameter size of the five through grooves 23 is larger than the outer diameter size of the connection bolts 25, which is convenient for pulling out the connection bolts 25 from the through grooves 23.
