[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0021] Embodiment 1
[0022] Please refer to Figure 1- Figure 4 The utility model provides the following technical scheme: a double -end torsion spring tension testing arrangement of avoidable deformation, including support 1 and the top end of support 1 erects and installs gantry 2, the inside installation of gantry 2 has test fixture 3, the top of support 1 and the front end of one side of gantry 2 is connected with control panel 4, the top of support 1 and the inside of gantry 2 installs fixed block 5, the recess inside of fixed block 5 is longitudinally installed with guide rod 6, the surface of guide rod 6 is connected with mounting block 7 through activity, the front end of mounting block 7 is connected with illuminating lamp 8, the mounting ear of illuminating lamp 8 is connected with bolt 9, the inside of mounting block 7 is equipped with spring 10, the both ends of spring 10 are installed with limit block 11, the inside wall of the recess of fixed block 5 is provided with limit slot 12.
[0023] In the implementation preferred: limit block 11 is connected between spring 10 and mounting block 7 to form elastic expansion connection.
[0024] In the implementation preferred: the end of limit block 11 is arc-shaped, and limit slot 12 is matched with limit block 11.
[0025] In the implementation preferred: mounting block 7 is connected between limit block 11 and fixed block 5 to form elastic clamping connection.
[0026] In the implementation preferred: illuminating lamp 8 is connected between bolt 9 and mounting block 7 to form detachable fixed connection.
[0027] In the embodiment, first, the double-end torsion spring is fixed on the test fixture 3, then the test fixture 3 is started by the control panel 4, and the two test fixtures 3 are opened to stretch the double-end torsion spring. Next, the tensile testing device, a tensile testing machine with model TL-1000, tests whether the double-end torsion spring is deformed during the stretching process. It is worth noting that the tensile testing device itself belongs to the existing mature technology.
[0028] During the tensile testing process, the power supply of the illuminating lamp 8 needs to be manually connected. Once the illuminating lamp 8 is started, its light will directly irradiate on the double-end torsion spring. The personnel observe the double-end torsion spring through the irradiation position of the illuminating lamp 8. Then, the operator can dial the mounting block 7 to move along the surface of the guide rod 6, so as to change the position of the illuminating lamp 8. While the position of the illuminating lamp 8 is adjusted, the irradiation position is also changed, so that the double-end torsion spring can be carefully observed according to the change of the irradiation position. This design makes the test condition be easily observed during the tensile testing of the double-end torsion spring, and the subtle cracks can be clearly identified.
[0029] In addition, when the mounting block 7 is moving, the limiting block 11 will extrude the limiting groove 12, so as to compress the spring 10 which is extruded and shrunk. This design ensures that the shrunk limiting block 11 will not affect the movement of the mounting block 7.

[0031] Please refer to Fig. 1- Figure 4 The bottom end of the support 1 is connected with a sleeve 13, the inside of the sleeve 13 is threadedly connected with a supporting leg 14, and the top end of the support 1 is connected with a level bubble 15.
[0032] In the preferred embodiment of the present application, the supporting leg 14 is threadedly connected with the sleeve 13.
[0033] In the embodiment, the supporting leg 14 is manually held and rotated to be removed from the inside of the sleeve 13, and then the four supporting legs 14 are placed on the ground in sequence. Next, the position of the level bubble 15 is observed to determine whether the tensile testing device is in a horizontal state. This step effectively avoids the deviation between the tensile direction and the actual stress direction of the sample, thereby improving the accuracy of the test, ensuring that the tensile force can accurately act on the sample, and thereby improving the overall test precision.
[0034] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of the technical features.
