Background
Along with the improvement of scientific research level and the development of medical technology in China, the scale of a biological sample library is gradually enlarged, and the demands for biological sample transfer are increasingly increased.
In the prior art, however, the mechanical gripper relies on friction to grip the article by applying two opposing gripping forces to the article to be gripped. However, for some articles, the maximum clamping force allowed to be applied is limited, and insufficient clamping force can cause the mechanical clamping jaw to be loose, thereby causing the article to fall off the mechanical clamping jaw during the grabbing process. For biological samples, they are often of high value, as they fall off during grasping, which can result in significant losses.
Aiming at the pain point, in the prior art, a mechanical gripper capable of preventing objects from falling off in the grabbing process is provided, for example, chinese patent publication No. CN217890983U discloses a discharging manipulator for producing an aluminum shell of an LED lamp, which comprises a fixing frame, a power piece, a connecting piece, a clamping jaw assembly and an anti-falling piece, wherein the power piece is matched with the fixing frame, the connecting piece is connected with the power piece in a sliding manner, the connecting piece is connected in a cavity of the fixing frame in a sliding manner, the clamping jaw assembly is matched with the connecting piece, and both sides of the fixing frame are rotationally connected with the anti-falling piece.

It can be seen that in this patent, the anti-falling member supports the gripped article from one side by the turning movement of the baffle, however, this has a certain limitation on the size of the article, for example, when the size of the article is large, the turning angle of the baffle is blocked by the article, so that the baffle cannot be turned in place, and thus it is difficult to support the article effectively. Resulting in limited practical use of the patent. The biological sample library usually stores biological samples with various sizes, which makes the technical scheme disclosed in the patent unable to meet the use requirement, so the application provides a mechanical gripper with an anti-slip protection structure, which is applicable to various sizes.
