Fixing jig for chip testing

Abstract

This utility model relates to the field of chip testing technology, specifically a fixing fixture for chip testing. It includes a fixing base, a pressing post, multiple pushing arms, and a multi-directional push-pull mechanism capable of simultaneously driving the multiple pushing arms to slide. The multiple pushing arms slide horizontally within the fixing base, with a retaining plate fixed to the upper end of each pushing arm. The retaining plate slides on the upper surface of the fixing base via the pushing arms. The pressing post is located between the multiple pushing arms and slides vertically within the fixing base, with its upper end exposed. Multiple retaining plates abut against the sides of the exposed portion of the pressing post. A fixing groove is formed on the upper end face of the pressing post, and a return spring is provided between the lower end face of the pressing post and the bottom wall of the fixing base. The multi-directional push-pull mechanism is installed within the fixing base. This design solves the problem of time-consuming chip fixing in existing chip testing fixtures.
