[0028] Preferably, the transverse frame 2 includes a transverse plate 21 and a first transverse tube 22. The longitudinal width of the transverse plate 21 is greater than the longitudinal width of the first transverse tube 22.

The end of the first pressure plate 42 away from the first bolt 43 contacts the plate, and the first bolt 43 at the other end is rotated until the protrusion 413 contacts the lower surface of the transverse plate 21, thereby pressing and fixing the plate. In use, the second fixing mechanism 4 is used to fix the transverse edge of the plate.

The insertion block 56 is inserted into the limiting groove 570, and the upper and lower surfaces of the insertion block 56 are in contact with the limiting block 57 and the longitudinal frame 1, respectively.

[0038] When using the third fixing mechanism 5 for fixing, such as Figure 7 As shown, place the aluminum plate 10 on the longitudinal edge of the transverse frame 2. Then insert the insertion blocks 56 at both ends into the limiting grooves 570, and rotate the second bolt 54 until the second pressure plate 53 presses the aluminum plate 10. The third fixing mechanism 5 is used to fix the longitudinal edge of the plate and facilitates fixing as follows. Figure 7 The L-shaped aluminum plate 10 shown.

[0039] When aluminum plate 10 is removed, insert block 56 is pulled out from limiting groove 570.

The lower part of the longitudinal frame 1 is fixedly connected to the base 11, and the two ends of the second transverse tube 23 are fixedly connected to the longitudinal frame 1, which serves to strengthen the structural strength.
