Referring to fig. 9, 10 and 11, in an embodiment, a third rib 244 is integrally formed on a side of second rib 207 away from buckle 210, and a side of second rib 207 away from buckle 210 and an inner side of third rib 244 form a receiving cavity 241. Through the arrangement mode that the accommodating cavity 241 is formed by the second rib plate 207 and the third rib plate 244, on the premise of ensuring the functions, one surface of the second rib plate 207 can be effectively utilized, and compared with the arrangement of the independent accommodating cavity 241, the number of parts is reduced, the weight of the body 200 is reduced, the weight of the whole connecting structure is reduced, and the carrying and the operation are convenient. It should be noted that, in addition to the above arrangement, the accommodating cavity 241 may be arranged to include, but not limited to, an inner concave cavity opened on the outer surface 100 of the inner ring plate 203.

The following are the processes of mounting and dismounting the first connection end 10 and the second connection end 20:

the installation process comprises the following steps: under a natural state, the first spring 209 has an upward elastic acting force on the buckle 210, so that the buckling portion 212 of the buckle 210 is located at a buckling position, when the second connection end 20 and the first connection end 10 gradually approach each other, the second connection end 20 jacks up the buckling portion 212 of the buckle 210, when the second connection end and the first connection end further approach each other, the buckling portion 212 continues to be jacked up, and the buckle 210 rotates relative to the body 200 with the connection portion 214 as an axis, and then the pressing portion 211 presses down the first spring 209, when the second connection end and the first connection end continue to approach each other, the buckling end 213 of the buckle 210 is clamped into the clamping groove 101 under the effect of the resilience of the first spring 209.

The disassembling process comprises the following steps: rotating the housing 220 of the second connection end 20, rotating the pressing block 230 to a position abutted to the buckle 210 along with the housing 220, and pressing the buckling part 212 of the buckle 210, wherein the buckle 210 is in an unlocked state (a state that the buckling part 212 is separated from the slot 101) due to the deformation of the first spring 209 caused by pressure, the buckling end 213 of the buckle 210 is separated from the slot 101, and meanwhile, the stopper 243 clamped between the two ends of the second spring 242 compresses a part on one side of the rotation direction along with the rotation force, so that the first connection end 10 is pulled out in a direction away from the second connection end 20, and the first connection end 10 is separated from the second connection end 20; when the external force for driving the housing 220 to rotate disappears, the resilience of the compressed portion of the second spring 242 and the resilience of the stretched portion of the second spring 242 act on the stop 243 to force the stop 243 to return, the stop 243 drives the rotating housing 220 to return to the initial position, the pressing block 230 leaves the buckle 210, and the buckle 210 restores the locking state (the state that the buckling part 212 is locked in the slot 101) under the resilience of the first spring 209.
