The material of block 2 is plastics.
Compared with prior art, the present invention has the following advantages：
1st, camera lens after finishing assembly, using the axiality between projection or real scene shooting detection group, it is found that axiality exceeds model
Enclose, then axiality is finely adjusted using the mechanism of the present invention, meet the axiality between group and require, realize camera lens solution picture
Uniformity requirement, solves the problems, such as camera lens solution as uneven, it is adaptable to which security protection etc. needs to constitute optical system by multiple groups
Camera lens product.
2nd, present configuration is simple, easy to use, only need to turn expansion screw by a primary screw, and guide shaft regulating block is just
The group mobility being enclosed within guide shaft can be further driven to by top pressure so as to drive guide shaft to move, realize the tune of axiality between group
Section, can effectively reduce dimensional accuracy, the tolerance of single product of composition camera lens, be easier production and management and control, greatly save
Cost.
3rd, the present invention can adjust the axiality between camera lens group after the completion of lens assembling, effectively reduce returning for component
Number of times is repaiied, the waste of resource is reduced, it is cost-effective.
4th, present configuration is simple, and structure itself with shading, and can not need extra light-shielding structure, structure design itself
There is dustproof construction, and do not need extra dustproof construction dust-proof, material-saving cost saves assembling time cost.
