Abstract
Description
Technical Field

[0002] Many instruments and large machines used in life use springs of different sizes and functions, and in the process of producing springs, it is necessary to test the resetting effect of the springs. The spring body is installed inside the test box, and the electric push rod drives the pressure plate into the test box to test the resetting effect of the spring. However, this method has some problems. Because the spring is usually cylindrical, when it is placed in the test box, a certain gap will be left between it and the test box. When the pressure plate is squeezed, the spring may bend, which affects the accuracy of the test results. In addition, due to the internal space limitation of the test box, this method can only be used for spring testing of the same size, which limits the scope of use of the device. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] 1.
