Through the rotation of the rotating rod 4, the three support rods 6 can be driven to rotate synchronously, and then the sliding support block 7 can be driven to move synchronously. Under the action of the three vertical plates 8 and the horizontal plate 10, the horizontal plate 10 and the clamping block 11 are moved toward the center synchronously to achieve tight and stable limiting of springs with different inner diameters.

Then, the spring to be tested is placed between the three clamping blocks 11, so as to facilitate the tight and stable limiting of springs with different inner diameters to be tested, and facilitate accurate adaptation to diverse spring specifications.

[0034] Then, the electric push rod 18 is controlled to drive the circular plate 3 and the detection block 2 to move in the vertical direction, and cooperates with the clamping block 11 to clamp and fix the top of the spring to be tested. Then, the motor 1304 is controlled to work, and the output shaft of the motor 1304 drives the rotating plate 1305 and the rotating column 1306 to rotate synchronously. Combined with the arc groove at the movable plate 1302, it is convenient to drive the guide plate 1301 to move repeatedly in the vertical direction, and then drive the circular plate 3 and the detection block 2 at the bottom to move repeatedly in the vertical direction, and then perform multiple periodic squeezes on the spring to be tested, so as to efficiently and comprehensively evaluate its fatigue tolerance.
