Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-4, a kind of lens cap fixing device, including mirror head outer shell 1, lens cap 2, the top left of mirror head outer shell 1
It is provided with connecting seat 3 at the center of side, connecting seat 3 and mirror head outer shell 1 are formed in one structure, and the left surface of connecting seat 3 is provided with blind
Hole chute 4, is provided with sliding block 5 in blind hole chute 4, and sliding block 5 is interior to be provided with spring 6, the both ends of spring 6 respectively with blind hole chute 4
The medial surface of side and sliding block 5 is flexibly connected, and the left end of the two side of connecting seat 3 is provided with flange connector, and flange connector is provided with
Connecting hole, the horizontal range of the axial line of connecting hole to the left end face of mirror head outer shell 1 are the half of connector thickness, connecting hole
Axial line is more than the axial line of connecting hole to the distance on the top of connecting seat 3, the top of lens cap 2 to the distance on the top of mirror head outer shell 1
It is provided with connector 7 at portion's right center, connector 7 and lens cap 2 are formed in one structure, on the two sides of connector 7 respectively
