[0028] In this embodiment, the first vertical support plate 10 and the second vertical support plate 20 have the same structure, and both the first vertical support plate 10 and the second vertical support plate 20 include a vertical steel plate 1 and a support frame 2, the support frame 2 includes two vertical channel steels 2-1 attached to the vertical steel plate 1 and a plurality of transverse channel steels 2-2 disposed between the two vertical channel steels 2-1 and attached to the vertical steel plate 1, and a reinforcement block 2-3 is disposed between two adjacent transverse channel steels 2-2;

[0029] The outer sleeve 3 and the inner screw 5 are arranged at the connection between the transverse channel steel 2 - 2 and the vertical steel plate 1 , and a stiffening plate 6 is arranged between the outer sleeve 3 and the inner screw 5 and the connection between the transverse channel steel 2 - 2 and the vertical steel plate 1 .

[0030] In this embodiment, the bottom of the vertical steel plate 1 extends out of the bottom transverse channel steel 2 - 2 , and an inclined steel plate 9 is provided between the bottom of the vertical steel plate 1 and the bottom transverse channel steel 2 - 2 .

[0031] In this embodiment, two symmetrically arranged ear plates 2 - 4 are provided at the top of the front and rear ends of the first vertical support plate 10 and the second vertical support plate 20 , and a U-shaped ring 2 - 5 is provided in the ear plate 2 - 4 .

[0032] In this embodiment, a pipe 7 is provided at the bottom of the groove 8 , and the pipe 7 is located between the first vertical support plate 10 and the second vertical support plate 20 , and below the telescopic support rod 30 .

[0033] In this embodiment, there are four telescopic support rods 30 , which are symmetrically arranged up and down and front and back between the first vertical support plate 10 and the second vertical support plate 20 .

[0034] In this embodiment, in actual use, the length of the other end of the inner screw 5 extending into the outer sleeve 3 is less than the length of the outer sleeve 3, which is convenient for adjustment.

[0035] In this embodiment, in actual use, the openings of the vertical channel steel 2-1 and the transverse channel steel 2-2 are welded to the vertical steel plate 1, the edge of the vertical channel steel 2-1 is flush with the edge of the vertical steel plate 1 in the height direction, the top transverse channel steel 2-2 is flush with the top of the vertical steel plate 1, and the bottom of the vertical channel steel 2-1 and the bottom transverse channel steel 2-2 are higher than the bottom of the vertical steel plate 1.
