Monitor lens positioning assembly

The invention relates to a monitor lens positioning assembly. The monitor lens positioning assembly comprises a positioning sleeve and a locking member. The positioning sleeve comprises a sleeve part. At least two through trough areas which are parallel with the axial direction are formed at the peripheral edge of the sleeve part. The locking member can be locked at the sleeve part of the positioning sleeve. Then a threaded projected rod of the lens is locked in the sleeve part. Afterwards through rotating the locking member, the sleeve part can generate a clamping force which is applied in the radial direction of the threaded projected rod, thereby stably positioning the lens and preventing shakes. 本发明是关于种监视器镜头定位组件，该监视器镜头定位组件包含有定位套筒及锁固件，该定位套筒包含有套筒部，于套筒部周缘形成与轴向平行且至少两个的通槽区，可将锁固件锁入定位套筒的套筒部处，再将镜头的螺纹凸杆锁入套筒部内部，而后仅须旋动锁固件，套筒部即可产生加诸于螺纹凸杆径向的夹合力，而使镜头被稳固定位而不会产生晃动的情形。
