Lens radial gap adjusting mechanism

The invention provides a lens radial gap adjusting mechanism. The adjusting mechanism comprises an adjusting device, one end of the adjusting device penetrates through a lens cone and a sliding sleeveof a lens and then is connected with a lens frame, and the other end of the adjusting device is exposed out of the lens cone and can drive the lens frame to move in the radial direction after force is applied to the end of the adjusting device. The adjusting device is installed on the lens cone, force is applied to the adjusting device from the outside to drive the lens frame to move, and the gapbetween the lens frame and the sliding sleeve can be adjusted, so the imaging effect is guaranteed; and adjustment is conducted through a mechanical structure, so the problem that at present, the imaging effect cannot be guaranteed due to the fact that the fit clearance between the lens frame and the sliding sleeve depends on machining precision is solved. 本发明提供了一种镜头径向间隙调节机构，采用的方案是：包括调节装置，所述调节装置的一端穿过镜头的镜筒、滑套后与镜架连接，所述调节装置的
