End both sides are respectively provided with the groove that can accommodate snap fit, and the groove one end is bent to form the second hook groove, while the groove also has second
Contact surface, and first hooks the overbending direction of groove and the second hook groove on the contrary, groove mutually fastens, first connects when the first hook groove and the second hook
Contacting surface and the second contact surface complete the rotation connection of outer scissor and bottom plate when cooperating.
Wherein, it is arcwall face away from the second side surface for hooking groove on groove, to form the second contact surface；On the snap fit
It is arcwall face away from the first side surface for hooking groove, to form the first contact surface.
Further, groove, which is provided with, can prevent the first hook groove and second from hooking groove release, the first of outer scissor disengaging bottom plate
Block, the surface that first block is in contact with snap fit respectively constitute the second contact surface and the first contact surface.
Particularly, the can engage the first block the 3rd hooks groove on snap fit, first block is in contact with the 3rd hook groove
Surface respectively constitute the second contact surface and the first contact surface.
Preferably, the notch of the first block can be accommodated by being opened up on snap fit, the surface that first block is in contact with notch point
The second contact surface and the first contact surface are not formed.
Wherein, the first block is column structure.
Preferably, connecting hole is offered on the shear arm of outer scissor, connecting shaft is accordingly provided with interior scissor, should
Connecting shaft inserts connecting hole to realize the mating connection of outer scissor and interior scissor.
Beneficial effect：Compared with prior art, remarkable advantage of the invention is：First the button modular structure by bottom plate with
The structure that outer scissor is connected with each other is improved, and the perforate in the structure and bottom plate on bottom plate is reduced, so as to realize enhancing key
The purpose of disk intensity, the service life of prolonging keyboard；Secondly connection between the button modular structure bottom plate and outer scissor is more
Firmly so that scissor preferably supports connection keycap, strengthens the use sense of touch of keycap, there is preferable Consumer's Experience.
