When the bent rod body 9 is assembled and connected to the first scissors-type connection element 4 and the second scissors-type connection element 5, the second side 92 of the bent rod body 9 is engaged with the third arm 524 of the second outer frame 52. On the limit hook 5241 , the fourth side 94 of the bent rod body 9 engages with the limit hook 4251 on the second arm 425 of the first outer frame 42 .

Structurally, the larger bent rod body 3 surrounds the smaller bent rod body 9, and in order to strengthen the structural strength of both, the first side 31 of the bent rod body 3 and the second side of the bent rod body 9 can also be The sides 91 are fixed together, for example joined by welding.

In addition, the bent rod body 9 can be a continuous structure without a break point, or have a break point, for example, a break point 95 is formed on the second side 92 of the bent rod body 9 . Regardless of whether there is a break point, the strength provided by the bent rod body 9 is sufficient to be used in the button 1 provided by this embodiment to connect the first scissors-type connection element 4 and the second scissors-type connection element 5, and strengthen Its structural strength, balance and linkage between the two. In addition, on the third arm 524 of the third outer frame 52 of the second outer scissors-type connection element 5 , an upright retaining wall 5242 can also be provided in the limit hook 5241 according to the design of the breaking point 95 . When the 9 groups of bent rods are installed on the second scissors-type connecting element 5, the breakpoint 95 can be inserted into the two ends of the retaining wall 5242 so that the retaining wall 5242 is engaged in the breakpoint 95, and this kind passes through the retaining wall 5242 The design of filling the breakpoint 95, in addition to making the breakpoint 95 not easy to be found and maintaining the integrity of the appearance of the bent rod body 9, also makes the bent rod body 9 closer to a closed structure, increasing the bending capacity. The structural strength that folding bar body 9 can provide.

The button 1 provided by the present invention can provide the structural strength and balance of the two scissor-type connecting elements 4 and 5 by bending the rod body 3 or 9, and also improve the linkage between the two scissor-type connecting elements 4 and 5 To improve the stability of the key cap 2 of the key 1 during the lifting and moving process.

The button 1 provided by the present invention can be replaced with bent rods 3 or 9 of different materials, weights or characteristics according to the requirements of different specifications. The weight or material can be adjusted according to or adjusted by bending the rod body 3 or 9, and will not be limited by the material or structure of the original first scissors-type connection element 4 or the second scissors-type connection element 5.
