Further, as shown in fig. 1 to 4, the first longitudinal beam 12, the second longitudinal beam 14, the cross beam 16, the first reinforcing plate 20 and the second reinforcing plate 30 of the frame 1 are all provided with lightening holes, so as to further lighten the frame 1, thereby realizing the overall lightweight design of the frame 1.
