The installation method is simple, quick and convenient.

It is highly practical.

[0023] In this embodiment, the first positioning structure includes a first positioning groove 111 formed on the right connecting part 11 and a first positioning protrusion 141 fixedly connected to the inner wall of the left insertion cavity 14.
