Technical Field

[0001] The utility model relates to the technical field of anti-twisting performance testing, in particular to a metal rod anti-twisting performance testing device. Background Art

[0002] Torsion resistance testing refers to evaluating the ability of a material or structure to resist torsional deformation through a series of tests. This test is usually used to describe the mechanical properties of metals or other materials, expressed as the ratio of torque to the corresponding angle of rotation. Torsional strength is one of the important parameters for evaluating and designing structural components to ensure that they can work safely and stably under various load conditions. Torsion resistance test methods include torsion tests, tension and compression tests, bending tests, etc., which aim to provide the response and performance indicators of materials or structures when subjected to torsional loads; existing metal material products often need to be repeatedly tested for the strength of the material before they are put on the market, so that the results obtained after multiple tests meet the composite standards before they can be put into use.

[0003] A Chinese patent discloses a device for testing the anti-twisting performance of a light strip (authorization announcement number CN 214309412 U). The patented technology can fix and straighten the light strip to be tested by setting a first fixing member, a second fixing member and a straightening assembly, and then repeatedly twist the light strip to be tested through a driving device connected to the second fixing member to test the torsional performance of the light strip, thereby accurately judging whether the light strip meets the design requirements, with high test efficiency and reduced labor; however, the device has a small scope of application, the test results are too cumbersome, and it is not convenient to draw conclusions; and it is not convenient to replace the clamping tool.
