Although the second connecting seat 204 is pivotally opened with respect to the first connecting seat 203 in the present embodiment, the two structures are not limited thereto, and other structures for detachably connecting the two are possible. For example, both sides of the second connection holder 204 are connected to the first connection holder 203 by a detachable structure.

Of course, besides the above-mentioned mating cavity 233 being disposed in the first connecting seat 203, the mating cavity 233 may also be disposed between two connecting seats, or the mating cavity may be disposed in the second connecting seat 204 and the fixing post 223 disposed in the first connecting seat 203.

As shown in fig. 6, the connecting member 300 has a polygonal line shape, and is composed of a first connecting member 311 and a second connecting member 312 which are connected to each other, and are arranged at an included angle of 135-170 °. The first connector 311 has a flat linear shape, and the second connector 312 has a round bar shape, which are connected by a transition portion to form the connector 300.

Of course, the connector 300 may have a detachable line shape or a curved shape, and the curvature may be different in each portion.

As shown in fig. 8 and 9, the connection base 201 includes a base body 241, a guide ring 243 is disposed on the base body 241 to guide the rotation of the first connection base 203 relative to the connection base 201, and the guide ring 243 may be disposed continuously or discontinuously. The connection base 201 and the first connection seat 203 are further provided with connection holes 205 correspondingly arranged, respectively, so that screws can penetrate through the two connection holes 205 to rotatably match the first connection seat 203 to the connection base 201.

As shown in fig. 2 and 4, the first base 100 further includes a position-limiting portion 102 disposed outside the connecting column 101 for limiting the connecting element 300 to prevent the connecting element 300 from falling off when the connecting element 300 is coupled to the connecting column 101 through the connecting hole 3314.

In this embodiment, the first base 100 includes a base main body 110 and a limiting member 120 fitted thereon, the base main body 110 is provided with a limiting cavity 111, the upper end of the limiting cavity 111 is provided with a limiting pivot base 112, the upper end of the limiting member 120 is provided with a limiting pivot 121, and the limiting pivot 121 is fitted in the limiting pivot base 112, so that the limiting member 120 can be pivotally fitted on the base main body 110. The limiting member 120 is provided with a stop member 122 at a lower end thereof, the stop block 113 is provided at a lower end of the limiting cavity 111, and the stop member 122 is engaged with the stop block 113 to limit the pivoting of the limiting member 120. A spring seat 114 is further disposed in the limiting cavity 111, and one end of a spring (not shown) is fitted on the spring seat 114, and the other end of the spring abuts against the limiting member 120.
