When the lifting plate 220 is driven to move up and down by the pressing driving piece 210, the clamping block 240 is far away from the pressure sensor 230, so that the pressure reading of the pressure sensor 230 is zero, when the lifting plate 220 is driven to move down by the pressing driving piece 210, the pressing block 310 is lifted up relative to the lifting plate 220 along with the abutting of the pressing block 310 and the base 100, so that a spring clamped between the pressing block 310 and the lifting plate 220 is compressed under the action of force, and meanwhile, the displacement sensor 320 is pushed by the pressing block 310 to detect the displacement of the pressing block 310 relative to the lifting plate 220, and the lifting plate 220 reacts the elastic thrust of the spring to the pressure sensor 230, so that the pressure sensor 230 displays the reading of the elastic thrust of the spring. Thus, the force sensor 230 and the displacement sensor 320 are used to accurately detect the spring force and displacement, so that a worker only needs to load and unload the spring during operation, thereby improving the detection accuracy of the spring. And the spring is pushed and compressed by the pushing-down driving member 210, so that the spring detection device can be suitable for high-elasticity spring detection.
