Of course, in other embodiments, the two electrical switches 7, the elastic arm 21 and the pressing cover 3 may be disposed asymmetrically, and the embodiment is not particularly limited.

Illustratively, for convenience of processing, the elastic arm 21 and the fixing portion 22 are integrally formed, that is, the elastic connecting member 2 is an elastic sheet as a whole. Of course, in other embodiments, the embodiment is not particularly limited as long as the elastic arm 21 can have elastic force.

Furthermore, the fixing portion 22 is provided with a mounting cylindrical hole 221, and the axial direction of the mounting cylindrical hole 22 coincides with the operation axis a, so as to realize that the elastic connection member 2 is disposed on the base 1 and ensure that the two pressing covers 3 can swing independently along the operation axis a, the fastening member 11 is inserted into the mounting cylindrical hole 22, and two ends of the fastening member 11 are connected with the base 1 respectively to form a positioning and supporting effect on the elastic connection member 2.

As shown in fig. 4, the pressing cover 3 includes a top plate and two side plates, the top surface and the bottom surface of the top plate are an operation surface 301 and a contact surface 302, respectively, and the protrusion 31 is disposed on the contact surface 302 in this embodiment.

Specifically, as shown in fig. 4 and 5, for maintenance convenience, a buckle 32 is provided on one of the pressing cover 3 and the elastic arm 21, and a locking groove 211 capable of being matched with the buckle 32 is provided on the other, so that the pressing cover 3 is detachably connected to the elastic connection member 2. In this embodiment, the latch 32 is disposed on the contact surface 302, and the engaging groove 211 is disposed on the elastic arm 21. Of course, in other embodiments, other detachable structures may be used to connect the pressing cover 3 and the elastic connecting member 2, and the embodiment is not particularly limited.

Optionally, the buckle 32 is provided with a guide slope so as to play a guiding role when the pressing cover 3 is disassembled and assembled, thereby improving the disassembling and assembling efficiency.

In this embodiment, in order to avoid that the elastic connection member 2 has too much resilience after being pressed when only using the buckle 32 to cooperate with the clamping groove 211, and then the pressing cover 3 is separated from the elastic connection member 2, the elastic arm 21 further includes two supporting bars 212 arranged at intervals along the direction of the operation axis a, and the pressing cover 3 is inserted into the supporting bars 212, so as to further support and fix the pressing cover 3. Of course, in other embodiments, only the supporting bar 212 may be inserted into the pressing cover 3, as long as the elastic connection member 2 is stably connected to the pressing cover 3, and the embodiment is not particularly limited.

Specifically, in order to realize the insertion of the supporting bar 212 with the pressing cover 3, the inner walls of the two side plates opposite to each other are provided with the protruding blocks 33, and a gap exists between the protruding blocks 33 and the contact surface 302 of the pressing cover 3, and the supporting bar 212 can be inserted in the gap.

Further, press and to set up a plurality of lugs 33 on the two relative inside walls of cover 3 at interval to guarantee that the safety cover is pegged graft stably with support bar 212.

Further, in order to make the sealing member 5 more tightly connected to the electrical switch, the top end of the electrical switch 7 protrudes out of the positioning groove 41.

Wherein, sealing member 5 is made by elastic material to guarantee that the protruding portion 31 and sealing member 5 butt and then make sealing member 5 warp in order to press electrical switch 7 when the safety cover swings to the direction that is close to electrical switch 7, sealing member 5 stops pressing electrical switch 7 under self resilience force after the safety cover swings away from sealing member 5 in the opposite direction.

In addition, the overall elasticity of the electric switch 7 after the electric switch is installed together can be enhanced by arranging the sealing member 5 with a hollow interior on the outside of the electric switch 7, and when the pressing cover 3 presses the electric switch 7 under an external force, the sealing member 5 is stressed to deform and provide more effective buffer protection for the electric switch 7.

Further, the key operation device further comprises two reinforcing parts 6 corresponding to the electrical switches 7 one by one, the reinforcing parts 6 are arranged between the sealing parts 5 and the electrical switches 7, the sealing parts 5 can be pressed down when the pressing cover 3 swings, the reinforcing parts 6 are driven to start the electrical switches 7, namely, the stability of pressing the electrical switches 7 is improved through the reinforcing parts 6, and the feedback responsiveness of related electric control commands controlled by the electrical switches 7 is improved.
