Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows: each carrier has a plurality of positioning posts (the present invention is described in detail by taking the carrier sharing 32PCS positioning posts as an example).

The utility model provides a flexible jacking positioning mechanism, as shown in fig. 1 ~ 3, a flexible jacking positioning mechanism, includes bottom plate 1, and 1 both sides symmetry of bottom plate is equipped with riser 2, but riser 2 lug weld is at the top surface of bottom plate 1, and lift cylinder 7 is installed to the middle part of riser 2, and lift cylinder 7 adopts prior art, and lift cylinder 7 accessible fix with screw is at the lateral wall middle part of riser 2.

The two ends of the vertical plate 2 are symmetrically provided with slide rails 5, the slide rails 5 are connected with a slide connecting plate 6 in a sliding manner, the top of the slide connecting plate 6 is connected with a transition plate 3, and the transition plate 3 can be fixed on the top of the slide connecting plate 6 through screws.
