In addition, the switching between the high-position supporting state and the low-position supporting state is realized by using the mode that the high-position supporting frame 22 swings around the hinge shaft 24, compared with the mode that the supporting platform 2 is directly lifted up and down through a hydraulic cylinder or an air cylinder, the power output of the driving assembly 3 can be reduced, the pipeline connection is reduced, and the stability in state switching can be ensured.
Specifically, when the high-position support frame 22 is in a flat state, the swing end of the high-position support frame 22 falls on the power unit 1.
Specifically, the hinge shaft 24 of the elevated support 22 may be a pin shaft.
In order to further ensure that the high-position supporting frame 22 can be in a stable supporting state in the vertical state, on the basis of the above embodiment, when the high-position supporting frame 22 swings to the vertical state, a positioning pin 23 is connected between the high-position supporting frame 22 and the low-position supporting frame 21, as shown in fig. 2, the positioning pin 23 is used for locking the position of the high-position supporting frame 22.
When the high-position support frame 22 swings and is in a flat state, the positioning pin 23 is disengaged, and after the high-position support frame 22 swings to a vertical state, the positioning pin 23 is inserted between the high-position support frame 22 and the low-position support frame 21.
