[0009] Among them, the front end of the first connecting piece is hinged to the rear end of the second connecting piece, the front end of the second connecting piece is hinged to the hinge shaft, the hinge shaft is connected to the third connecting piece, and the third connecting piece is fixed to the middle and upper part of the lifting connecting rod.

[0010] Wherein, the lower end of the lifting connecting rod is hinged to the connecting plate, and the upper end of the lifting connecting rod is hinged to the back side of the chest support plate.

[0011] Wherein, the lower part of the hinged plate is fixed on the pedal.

[0012] Wherein, brackets are respectively provided on both sides of the pedal.

[0013] Wherein, the front part of the bracket and the connecting plate are fixed to each other.

[0014] The utility model also provides a transfer machine adopting the transfer machine lifting mechanism.

[0015] Compared with the prior art, the outstanding effects of the utility model are:

[0016] The lifting mechanism of the transfer machine of the utility model completely abandons the sling-type or lifting-type structural design, imitates the action mode of "one person carrying another person" in real life, is easier to operate, and is more comfortable for the user; in addition, the lifting mechanism of the transfer machine hinges the lifting motor on the back side of the chest support board, and drives the movement of the lifting connecting rod through the movement of the chest support board, so the controllability of the movement range is higher, avoiding the problems of excessive lifting range and difficulty in control caused by directly connecting the lifting motor to the first connecting plate or the second connecting plate.

[0017] The lifting mechanism of the transfer machine and the transfer machine of the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

The front ends of the two first connecting pieces 7 are respectively hinged to the rear ends of the two second connecting pieces 8, the front ends of the two second connecting pieces 8 are hinged to the hinge shaft 11, the left and right ends of the hinge shaft 11 each pass through a third connecting piece 12, and the two third connecting pieces 12 are each fixed to the middle and upper part of a lifting connecting rod 5. Among them, the upper end of the movable connecting rod 6 is hinged to each other with the hinge point between one of the first connecting pieces 7 and the second connecting piece 8.

[0024] There are two lifting connecting rods 5 which are parallel to each other. The lower ends of the two lifting connecting rods 5 are respectively hinged to a connecting plate 9 , and the upper ends of the two lifting connecting rods 5 are respectively hinged to the upper back of the chest support plate 4 .

[0025] The hinged piece 2 is Y-shaped, and the lower part of the hinged piece 2 is fixed on the pedal 1. Two brackets 10 are respectively arranged on both sides of the pedal 1. The front parts of the two brackets 10 are respectively fixed to the two connecting plates 9.
