It is easy for installation in third through-hole 532, it is compact-sized, it is more stable, firm；It is additionally provided on movable block 53 and is stretched out with first
The buffer board 56 that portion 422 matches, buffer board 56 are located between movable block 53 and the first extension 422, when camera module 4 by
When the external impacts arrived are greater than the magnetic attraction between movable block 53 and the first extension 422, the first extension of camera module 4
422 separate with movable block 53 and fall along guiding mechanism 52, under the first extension 422 and guiding mechanism 52 of camera module 4
After the elastic element 55 at end is in contact, after the buffer protection by component elasticity element 55,4 stop motion of camera module, silk
The rotation of linkage 51 again declines movable block 53, and movable block 53 can be with 422 weight of the first extension when dropping to certain position
New magnetic-adsorption connection, since movable block 53 can generate certain collision when magnetic-adsorption is connect again with the first extension 422
Power prevents movable block 53 from directly touching with the first extension 422, more so buffer board 56 can play the role of buffer protection
Add safe and reliable.
Preferably, the material of buffer board 56 can be using rubber, polyurethane or foam etc., and rubber is with elasticity is good, intensity
The advantages that high, cheap, polyurethane flexibility with higher, resilience, mechanical strength and oxidation stability and excellent
Oil resistivity the advantages that, foam have it is elastic, light-weight, quickly pressure-sensitive fixation, it is easy to use, be bent freely, volume is ultra-thin, property
Can be reliable the advantages that.
