Synthetic material production quality testing device

The invention discloses a synthetic material production quality testing device which comprises a rail base, and two sliding blocks which are driven by a power mechanism to move towards each other or move away from each other at the same time are connected to the inner wall of the rail base in a limited sliding mode. The inner wall, close to the bottom, of the rectangular frame body is fixedly connected with a fixed arm for positioning and preliminarily clamping a to-be-detected synthetic pipe, and a rotating arm which rotates in a single direction and is rotationally connected to the inner wall of the rectangular frame body through a fixed shaft is arranged above the fixed arm; and the opposite ends of the two rotating arms are fixedly connected with clamping claws which are matched with the end parts of the corresponding fixed arms and are used for clamping the composite pipe to be detected. Through cooperative use of the structures, the problems that in the actual use process, when traditional equipment for
