Fluid-driven material joint component used in grabbing and manipulation mechanisms, has concavity and internal vacuum, in which thickness of joint component in range of concavity is less than or equal to thickness in rest of joint component

摘要

The joint component is made of ductile polymer material, and formed with a semicircular, semi-elliptical or triangular cross-section. An internal vacuum (3) closed on one side, and a concavity (2) are formed on the joint component. The thickness of the joint component in the range of the concavity is less than or equal to the thickness in the rest of the joint component.
