The external threaded ring has external threads on its outside, and the internal threaded ring has internal threads on its inside.
[0010] In one embodiment, the outside of the insertion rod is covered with a rubber sleeve.
[0011] In one embodiment, the length of the insertion rod is five to ten centimeters.
[0012] In one embodiment, the snap-fit plate has an arc-shaped structure.
[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, after multiple sets of splicing rings are spliced together, the snap-fit block is taken out and snapped between two adjacent snap-fit slots. At the same time, the snap-fit plate will also enter the snap-fit slot, the positioning strip is inserted into the positioning slot, and then the insert rod is slid to allow the insert rod to be inserted into the positioning slot through the insertion hole. At the same time, the insert rod will also enter the through hole of the positioning strip. Then, by rotating the insert rod, the splicing and fixing of multiple sets of splicing rings can be completed. In summary, in this utility model, splicing rings can be quickly and conveniently disassembled and assembled, and it is convenient to repair and replace individual damaged positions.
