Platform, each supporting table are equipped with a pair of of limited post.
Preferably, the movable through-hole extends to form the stop collar close to the side of carrier.
Preferably, the carrier outside spacers are disposed with the carrying flange for carrying coil, and the coil, which is fastened on, to be held
It carries on flange, the annular groove is arranged in carrier lower end.
Preferably, the gap between the annular groove and the stop collar is 10~20mm.
Working principle: external dust granule is blown between carrier and shell via the through-hole one of shell and drops into bottom
On seat, the stop collar here being provided with engages with the annular groove of carrier lower end, and dust granule needs to climb over stop collar, and via limit
Gap between ring and the annular groove of carrier lower end can be adhered on camera lens, and external dust particle can not be adhered directly to mirror
On head.
Compared with prior art, the application has the beneficial effect that
1, in the application, the movable through-hole of pedestal is equipped with stop collar, and the stop collar and carrier lower end cooperate, can be effective
The dust granule of isolation outside adheres on camera lens, and external dust granule is blown into carrier and shell via the through-hole one of shell
Between and drop on pedestal, the stop collar here being provided with engages with carrier lower end, and dust granule needs to climb over stop collar, and passes through
Can be adhered on camera lens by the gap between stop collar and carrier lower end, due to carrier lower end annular groove and stop collar it
Between gap it is smaller, the problem of greatly reducing camera lens easy adhering dust；
2, in the application, the arc groove and stop collar of carrier lower end are snap-in structures, and carrier is limiting in focussing process
It is moved under the guiding role of ring along optical axis direction, has evaded the radial wobble problem in existing voice coil motor focussing process, improved
Focusing accuracy and accuracy.

Specific embodiment:
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combination is specifically illustrating and embodiment, furthers elucidate the utility model.
Embodiment 1:
As shown in Figure 1, a kind of voice coil motor dust preventing component, including pedestal 10, and the carrier 20 being adapted to pedestal 10；
10 upper surface of pedestal is equipped with stop collar 11, and stop collar 11 is embedded in the annular groove 21 of 20 lower end of carrier.
In the application, the movable through-hole 13 of pedestal 10 is equipped with stop collar 11, which matches with 20 lower end of carrier
It closes, the dust granule that can effectively completely cut off outside adheres on camera lens, and external dust granule is blown into via the through-hole one of shell
To between carrier and shell and dropping on pedestal 10, the stop collar 11 here being provided with engages with 20 lower end of carrier, dust granule
It needs to climb over stop collar 11, and can be adhered on camera lens via the gap between 20 lower end of stop collar 11 and carrier, due to
The problem of gap between the annular groove 21 and stop collar 11 of 20 lower end of carrier is smaller, greatly reduces camera lens easy adhering dust.
As shown in Fig. 2, pedestal 10 includes quadrate support plate 12, and through the movable through-hole 13 of quadrate support plate 12, it is living
