Screws and nuts are crucial fasteners on micro turbojet engines, and their static and dynamic mechanical properties and failure behaviors directly affect the engine's structural safety.

[0003] In the prior art, both ends of the standard screw and nut parts are cylindrical. During the tensile test, it is difficult for the clamp of the tensile testing machine to stably and firmly clamp both ends of the standard screw and nut parts. In order to ensure the accuracy of the tensile test value of the standard screw and nut parts, and at the same time save the storage space of the tensile testing fixture, it is particularly important to find a simple and accurate tensile testing fixture for standard screw and nut parts. Therefore, this application proposes an efficient standard part testing device to solve the above problems. Utility Model Content

During tensile testing, it is difficult for the clamps of the tensile testing machine to stably and firmly clamp both ends of the screw and nut standard parts. In order to ensure the accuracy of the tensile test value of the screw and nut standard parts, and at the same time save the storage space of the tensile testing fixture, it is particularly important to find a simple and accurate tensile testing fixture for screw and nut standard parts. Therefore, this invention proposes an efficient standard part testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
