[0037] The boss 2 comprises a flat plate part 21 parallel to the bottom plate 1 and a connecting part 22 for connecting the flat plate part 21 and the bottom plate 1, and the flat plate part 21 protrudes in a first direction to form a scissor leg hanging table 3 with the connecting part 22,

[0038] wherein the first direction refers to a direction parallel to the bottom plate 1 and perpendicular to the rotating direction of the assembly column of the scissor leg structure 6, so that the assembly column is rotatably connected to the bottom of the scissor leg hanging table 3;

[0039] The lower surface of the scissor leg hanging table 3 forms a first abutting area 8, and the side surface of the connecting part 22 towards the side of the scissor leg hanging table 3 forms a second abutting area 9, the first abutting area 8 and the second abutting area 9 form a limiting clamping groove 10 for clamping the assembly column of the scissor leg structure 6, and the scissor leg structure 6 is hingedly connected with the boss 2;

[0040] The bottom plate 1 is provided with a groove body 11 below each scissor leg hanging table 3, and the groove body 11 is used to accommodate the assembly column of the scissor leg structure 6.

[0041] It should be noted that the inner frame and the outer frame in the middle of the scissor leg structure 6 are connected, and there is a distance between each of them and the hanging table connecting end, so that after the scissor leg structure 6 is embedded in the limiting clamping groove 10, a constriction force is generated, and a hinged connection relationship is formed by friction.

[0042] By adjusting the structure of the bottom plate 1, the boss 2 and the scissor leg hanging table 3 connected with the scissor leg structure 6 can be directly stamped out by stamping, which improves the production efficiency and reduces the height of the scissor leg hanging table 3 relative to the bottom plate 1, and the elastic body 5 can be made thinner.

[0043] On the other hand, the contact area between the limiting clamping groove 10 formed by the boss 2 and the scissor leg hanging table 3 and the scissor leg structure 6 is significantly increased, improving the motion stability; the reduction of the height of the scissor leg hanging table 3 can shorten the height of the elastic body 5, and when the key cap is pressed downward, the stroke is shortened, making the key pressing sensitive and stable; the scissor leg hanging table 3 is directly formed by stamping process, without using 90° bending process to form a hook, so that harder materials can be used without worrying about the risk of bending and breaking.

[0044] As shown in the figure, Figure 2 The boss 2 and the bottom plate 1 are integrally stamped.

[0045] ​It needs to be explained that the stamping difficulty is reduced, and the yield is improved.

[0046] As Figure 2 and Figure 4 The connecting part 22 is provided with two, which are respectively arranged on both sides of the flat plate part 21, and the boss 2 is in the form of an open-bottomed trapezoidal structure.
