Example Embodiment
[0033] The present invention will be described in detail below in conjunction with the drawings.
[0034] The best embodiment of the invention Figure 2~Figure 9 As shown, it mainly includes a front plate 1, a first A-shaped truss 2, a second A-shaped truss 3, a third A-shaped truss 4, a fourth A-shaped truss 5, a fifth A-shaped truss 6, and a sixth A-shaped truss 7. , The seventh A-shaped truss 8, the rear plate 9. Seven groups of A-shaped trusses are combined with the front plate 1 and the rear plate 3 by threaded connection. The first A-shaped truss 2 and the seventh A-shaped truss 8 are symmetrically distributed on the left and right sides of the main support structure, and the second A-shaped truss The truss 3 and the sixth A-truss 7 are symmetrically distributed on the left and right sides of the main support structure, the third A-truss 4 and the fifth A-truss 6 are symmetrically distributed on the left and right sides of the main support structure, and the fourth A-truss...
