[0036] One end of the first movable plate 102a is hinged to one end of the second movable plate 102b, and the angle between them can be changed; the other end of the second movable plate 102b away from the first movable plate 102a is hinged to the inclined plate 102c; the inclined plate 102c can block the equipment placed on the second movable plate 102b to prevent the equipment from falling, and can also facilitate the transport of objects when the second movable plate 102c is tilted.

[0037] Preferably, a first side rod 102d is provided below the first movable plate 102a, a second side rod 102e is provided below the second movable plate 102b, and an elastic element 102f is provided between the first side rod 102d and the second side rod 102e.

[0038] The first side rod 102d is fixedly installed below the first movable plate 102a, and the second side rod 102e is fixedly installed below the second movable plate 102b. The elastic element 102f is preferably a tension spring, which can keep the first movable plate 102a and the second movable plate 102b in the unfolded state without the need for external force, making it convenient for handling operations.

[0040] Example 3, referring to Figures 1-2 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, except that when the first movable plate 102a and the second movable plate 102b move, the moving member 103 and the telescopic member 104 move.

[0041] Specifically, the movable component 103 includes a fixed frame 103a located below the first movable plate 102a and the second movable plate 102b, and a rotating wheel 103b is movably installed inside the fixed frame 103a.

The damping 104d ensures the smoothness and cushioning of the telescopic movement, reducing possible mechanical damage and noise.

[0046] Furthermore, when the first movable plate 102a and the second movable plate 102b need to move, the wheel 103b can move the first movable plate 102a and the second movable plate 102b in the horizontal direction. Under the action of the damping 104d, the movable cylinder 104b and the wheel 104c can make the second movable plate 102b extend and retract in the vertical direction, so that the handling mechanism can flexibly adapt to handling objects of different sizes and weights, while maintaining the stability and safety of operation.
