Thereby shortening the fixing time of the chassis frame body 1 and improving the convenience of the chassis frame.

[0024] like Figure 2 and Figure 3 As shown, driving racks 21 are fixedly connected to both sides of the two movable plates 17, and a plurality of sliding grooves 15 are provided on the inner wall of the chassis frame body 1.

[0031] When installing lifts of different sizes on the chassis frame body 1, first pull the fixing ring 26 to release the restriction of the hexagonal connecting rod 9, and then rotate the hexagonal connecting rod 9 to make the sliding plate 2 14 and the sliding plate 1 10 approach and move away from each other, and then loosen the fixing bolts 12 on the sliding plate 2 14 and the sliding plate 1 10, adjust the four I-shaped sliding blocks 13 to a suitable distance, and then fix the four corners of the lower end of the lift by the bolts on the four I-shaped sliding blocks 13 respectively.
