Abstract
The invention provides a laser light source universal back focusing device. A shaft sleeve which is in linkage with the inner end of a connecting rod through a mandrel is driven to rotate by rotating a focusing hand wheel to drive the connecting rod which is fixedly connected with the focusing hand wheel, and then an adjusting sleeve is driven to rotate by means of a universal rod which is in linkage with the shaft sleeve and the adjusting sleeve. Due to the fact that the adjusting sleeve is in threaded linkage with the inner wall of a shell body which is relatively static, the adjusting sleeve can move front and back in the axial direction, and then a laser tube base which is fixedly connected with the adjusting sleeve is driven to move front and back in the axial direction. Therefore, the adjustment of the focal distance of a laser light source by changing the position of the light source is achieved, and the defects in the prior art are overcome.
