[0008] As a further improvement of the above technical solution, the outer end of the support rod is provided with a first inclined surface, which is inclined upward, and the inner end of the branch is provided with a second inclined surface, which is inclined downward. When the branch is rotated and unfolded, the first inclined surface and the second inclined surface abut against each other.

[0009] As a further improvement of the above technical solution, the branches are integrally formed on the connecting piece.

[0010] As a further improvement of the above technical solution, a plurality of through holes are provided on the connecting member.

[0013] As a further improvement of the above technical solution, a slot or an annular boss is provided at the end of the support seat, and the annular boss of one support seat can be inserted into the slot of another support seat.

[0014] The beneficial effects of the utility model are as follows: by providing a notch matched with the connecting piece, the connecting piece and the support rod are stably rotatably connected, and at the same time, the depression cooperates with the arc-shaped protrusion to ensure that the branches remain stable after being rotated and opened.
