[0032] In this embodiment, all components are arranged on the basis of the base plate 1. The cylinder 32 is supported by the support plate 31 on the upper surface of the base plate 1. The output end of the cylinder 32 drives the top plate 33 to move parallel to each other back and forth. The sliders 34 connected at both ends of the top plate 33 are slidably connected to the inside of the T-slot 23 for limited movement.

[0034] In this embodiment, when the device is used to clamp and detect an object, the outermost No. 3 plate 7 first contacts the object, and then, when squeezing the object, it is subjected to the interaction force, causing the No. 3 plate 7 to make a circular motion around the No. 2 protrusion 65 through the limiting groove 2 73, and the No. 3 main board limiting block 72 slidingly connected to the inside of the No. 2 limiting groove 64 limits the rotation angle of the No. 3 plate 7; when the No. 3 plate 7 reaches the maximum rotation angle, the interaction of forces causes the No. 2 plate 6 to start rotating. Similarly, the No. 2 plate 6 makes a circular motion around the No. 1 protrusion 53 through the limiting groove 1 63, and the No. 2 main board limiting block 62 slidingly connected to the inside of the No. 1 limiting groove 52 limits its rotation angle; when clamping, the No. 1 plate 5, No. 2 plate 6, and No. 3 plate 7 of different sizes rotate and cooperate with each other, so that even special-shaped parts can be clamped more stably; after the part is clamped stably, the hardness tester 8 is used to test the hardness, and the hydraulic rod 83 squeezes the part, and the changes in the pressure gauge 84 are observed during the squeezing process.

[0035] Working principle: All components are arranged on the basis of the bottom plate 1. The cylinder 32 is supported by the support plate 31 on the upper surface of the bottom plate 1. The output end of the cylinder 32 drives the top plate 33 to move parallel to the front and back. The sliders 34 connected at both ends of the top plate 33 are slidably connected to the inside of the T-slot 23 for limited movement. When the top plate 33 moves, it drives the positioning component 4 to move together. The threaded rod 42 in the positioning component 4 passes through the bottom end of the No. 1 main board 51 and the cross plate 41. The bottom end of the No. 1 main board 51 is slidably connected to the inside of the cross plate 41. Therefore, when the crank 44 is shaken, the No. 1 main board 51 can be driven to move parallel to the limited position of the groove of the cross plate 41. Therefore, the output end of the cylinder 32 drives the top plate 33, the cross plate 41, and the No. 1 plate 5 to move together. When the device is used to clamp and detect an object, the outermost No. 3 plate 7 first contacts the object, and then squeezes it. When pressing an object, the interaction force causes the No. 3 plate 7 to make a circular motion around the No. 2 protrusion 65 through the limiting groove 2 73, and the No. 3 main board limiting block 72 slidingly connected to the inside of the No. 2 limiting groove 64 limits the rotation angle of the No. 3 plate 7; when the No. 3 plate 7 reaches the maximum rotation angle, the interaction of forces causes the No. 2 plate 6 to start rotating. Similarly, the No. 2 plate 6 makes a circular motion around the No. 1 protrusion 53 through the limiting groove 1 63, and the No. 2 main board limiting block 62 slidingly connected to the inside of the No. 1 limiting groove 52 limits its rotation angle; when clamping, the No. 1 plate 5, No. 2 plate 6, and No. 3 plate 7 of different sizes rotate and cooperate with each other, so that even special-shaped parts can be clamped more stably; after the parts are clamped stably, the hardness tester 8 is used to test the hardness, and the hydraulic rod 83 squeezes the parts, and the changes in the pressure gauge 84 are observed during the squeezing process.
