Novel device for testing shearing performance of polyvinyl chloride resin product

The utility model provides a novel device for testing the shearing performance of polyvinyl chloride resin products, which relates to the technical field of material performance testing and comprises a bottom plate, a sliding table is fixed at the top of the bottom plate, two supports are symmetrically connected to the top of the sliding table in a sliding mode, and rotary tables are rotatably connected to the opposite surfaces of the two supports. Clamping mechanisms are arranged on the opposite surfaces of the two rotary tables correspondingly, and driving mechanisms used for driving the corresponding rotary tables to rotate are arranged on the two supports correspondingly. Through the arrangement of the support, the rotary table, the clamping mechanisms and the driving mechanisms, a test product is clamped between the two clamping mechanisms, the two clamping mechanisms can be controlled by the two independent driving mechanisms to rotate respectively, and a person can set the two ends of the test product
