The matching structure of the slider 4 and the swing rod 5 is as follows: The swing rod 5 includes a rotating part 8 in the middle, a plurality of pressing rod parts 9 arranged on the outer periphery of the rotating part 8, and a linkage rod part 10 arranged at the top of the rotating part 8. The rotating part 8, the pressing rod parts 9 and the linkage rod part 10 are of an integral structure; An elastic ball head 11 is integrally arranged on the linkage rod part 10 of the linkage rod part 10. A ball hole 12 is arranged at the bottom of the slider 4. The elastic ball head 11 is press-fitted into the ball hole 12. Designing the ball head of the swing rod 5 into an elastic structure and press-fitting it with the ball hole 12 of the slider 4 can ensure the shaking amount of the button, and since the ball head is of an elastic structure, there is no risk of jamming when operating the button.
[0030] As shown in the attached Figure 5 figure, a plurality of relief partition grooves 13 are arranged on the elastic ball head 11, and the plurality of relief partition grooves 13 divide the elastic ball head 11 into a plurality of elastic blocks 14 that can deform radially inward and outward. The elastic blocks 14 can deform inward and outward when pressed, making it have elastic characteristics.
[0031] As shown in the attached Figure 5As shown, the relief partition groove 13 is in an L shape or a C shape. A plurality of relief partition grooves 13 are evenly distributed in a circumferential array on the elastic ball head 11. The elastic ball head 11 is provided with a reinforcing base 15 corresponding to the positions between the plurality of relief partition grooves 13. More specifically, in this embodiment, the number of relief partition grooves 13 is 4, and the reinforcing base 15 is in a shape with a cross section in a "cross" shape. This is the first structure of the elastic ball head 11, and its structure has the advantages of stability and reliability.
[0032] In addition, the relief partition groove 13 can also be in a straight line shape. A plurality of relief partition grooves 13 are evenly distributed in a circumferential array on the elastic ball head 11, and the inner ends of the plurality of relief partition grooves 13 are all interconnected. In this embodiment, the number of relief partition grooves 13 is 4, and the 4 relief partition grooves 13 are connected to form a "cross" shaped through groove.
