[0027] In the technical solution of the present utility model, as Figures 2-3 shown, the limiting mechanism 2 is fixed on the chassis 11 of the medical crane, the limiting mechanism 2 includes a fixing plate 201, a connecting plate 202 and a connecting screw 203, the left and right sides and the middle of the fixing plate 201 are respectively provided with card slots 12, a groove is provided in the middle of the fixing plate 201, a plurality of screw mounting holes 13 are provided on both the fixing plate 201 and the baffle 16, and the connecting screw 203 passes through the screw mounting holes 13 on the baffle 16 and the screw mounting holes 13 on the fixing plate 201 to connect the fixing plate 201 and the connecting plate 202; making the overall structure more reliable.

[0028] In the technical solution of the present utility model, as Figure 1 shown, the lever 1 includes a lever connecting rod 101, a swing arm 102 and a handle 103, the lever connecting rod 101 is connected to one end of the swing arm 102, and the other end of the swing arm 102 is sleeved with a handle 103; the handle 103 plays an anti-slip role to facilitate the use of the staff.

[0029] In the technical solution of the present utility model, as Figures 1-4As shown in the figure, a retaining pin 14 is provided on the connecting rod of the lever 1. The retaining pin 14 is engaged in the card slots 12 on the left and right sides of the fixed plate 201 by pulling the lever 1 left and right. The lever 1 is located between the fixed plate 201 and the connecting plate 202. First, pull the lever 1 backward to disengage the retaining pin 14 from the card slot 12, and then swing the lever 1 left and right to control the left foot plate 9 and the right foot plate 10.

[0030] In the technical solution of the present utility model, as Figure 1 shown in the figure, a left foot plate 9 and a right foot plate 10 are provided on one side of the chassis 11 away from the limiting mechanism 2.
