It has low practicality and is therefore inconvenient to use. Utility Model Content

[0008] Preferably, the surface of the connecting block is slidably connected to the inner wall of the shell and the surface of the slider, and the surface of the connecting plate is fixedly connected to the surface of the guide rod and the surface of the slide rod.

[0009] Preferably, the plurality of support frames are distributed in a circular array with the axis of the base plate as the center, and the plurality of clamping plates and the plurality of connecting plates are stacked.

[0010] Preferably, the surface of the fixed block is slidably connected to the surface of the sliding rod, and the two fixed telescopic rods are symmetrically distributed with the axis of the bottom plate as the center.

[0011] The beneficial effects of the utility model are:
