[0029] The first magnetic block 10 is moved by the slider 9;

[0030] The two first magnetic blocks 10 and the adjacent second magnetic block 11 are arranged to repel each other, and two slide slots 12 are opened inside the housing 1;

[0038] Working principle:

[0039] When the resistance probe 5 is subjected to an upward force, the base 3 is driven to move upward through the extension rod 4, so that the spring 2 absorbs energy and undergoes elastic deformation. Then, the base 3 drives the two sliders 9 to move upward through the two extension rods 4, and then the two sliders 9 drive the two first magnetic blocks 10 to move upward. When the two first magnetic blocks 10 move upward, the different upward positions cause the different repulsive forces with the second magnetic block 11, so that the resistance probe 5 can have better buffering. Then, the base 3 is reset through the elastic deformation of the spring 2, thereby ensuring the operation of the resistance probe 5.
