The provision of the fastener 40 facilitates the fixed connection of the first connecting member 20 and the second connecting member 30. Among them, the first connecting member 20 and the box body 10 are an integrally formed structure, so that when the first connecting member 20 and the second connecting member 30 fix the vertical rod 70 in the mounting hole, the vertical rod 70 can be more stably fixedly connected to the box body 10. And it is convenient for the processing of the first connecting member 20. In this way, by setting the first connecting member 20 as a structure integrally formed with the box body 10, and the second connecting member 30 being swingably connected to the first connecting member 20, when the box body 10 is separated from the vertical rod 70, the first connecting member 20 and the second connecting member 30 can both be connected to the box body 10, thereby reducing the loss of the first connecting member 20 and the second connecting member 30 during transportation, and improving the work efficiency when the vertical rod 70 and the box body 10 are disassembled. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the connecting member is easy to be lost during transportation and the work efficiency is low when the vertical rod and the box body are disassembled.

[0035] like Figures 1 to 6As shown, a first limiting arc surface 21 is provided on the side wall of the first opening groove, and a second limiting arc surface 31 is provided on the side wall of the second opening groove.
