[0002] In order to ensure the quality of the spring, it is necessary to perform a tensile test on the spring, so it is necessary to use a corresponding spring tensile test detection device. The existing spring tensile test detection device has the advantages of simple structure, light weight, convenient use, firm structure, and durability. Strong performance, high precision of tensile test, low equipment cost, etc., can meet the existing requirements for the use of spring tensile test detection, but for the existing spring tensile test detection device, on the one hand, in Spring compression test cannot be carried out at the same time when spring tension test is performed, or the detection position needs to be replaced and fixed again, which increases the time for spring fixation, which is not conducive to the rapid conversion of spring different performance tests. On the other hand, when the spring When fixing, it is easy to cause the spring to be skewed, which is not conducive to ensuring the accuracy of the detection. Moreover, when the spring is detected, the force-applying part is likely to cause inaccurate actual tension due to friction when the tension is increased, which affects the detection. Accuracy is not conducive to the accurate detection of the spring. On the other hand, when performing the tensile test of the spring, it is easy to make the tension greater than the tensile limit of the spring, which will cause the spring to be damaged, and it is impossible to effectively distinguish the tension of the spring. Whether the extension limit meets the standard requirements makes it difficult for some springs with slight quality problems to be detected, which is not conducive to ensuring the safety of the spring
