The shape of the horizontal mounting groove 3 may be various, such as a bar shape (including the case of traversing the front end face 2), a circular shape, or other shapes.
The principle of the cross-line light source is as follows: as shown in fig. 1 and 2, a vertical cylindrical mirror 12 is installed inside the front end of the cross-line light source, and forms a T-shaped distribution structure with a horizontal cylindrical mirror 11 installed on the end surface. The collimated laser beam emitted by the laser collimation point light source 13 is emitted from the light through hole 5 and is divided into two parts, one part penetrates through the horizontal cylindrical mirror 11, the other part penetrates through the vertical cylindrical mirror 12, and the light beam is transmitted, refracted and reflected in the horizontal cylindrical mirror 11 and the vertical cylindrical mirror 12 to form two mutually orthogonal laser plane light curtains; the laser line in a cross shape can be formed by irradiating the surface of the object.
In order to ensure the precision of the planar light curtain, the cylinders of the horizontal cylindrical mirror 11 and the vertical cylindrical mirror 12 must be perpendicular to the optical axis of the laser collimation point light source 13, which requires that the horizontal cylindrical mirror 11 and the vertical cylindrical mirror 12 can be precisely adjusted and positioned after being installed.
In order to facilitate the positioning and debugging of the two cylindrical mirrors, the method adopted in the scheme is to respectively set two debugging mechanisms of the cylindrical mirrors, wherein the vertical cylindrical mirror 12 is debugged through a pair of debugging saw slits 10 arranged at the front end of the shell 1, and the scheme mainly provides a debugging mechanism for adjusting the horizontal cylindrical mirror 11:
positioning grooves 4 are formed in the horizontal mounting groove 3, and a pair of positioning grooves 4 are arranged and distributed on two sides of the light through hole 5; the pair of positioning grooves 4 can be in the same shape, symmetrically distributed and in different shapes; the maximum width of the positioning slot 4 should be smaller than the diameter of the horizontal cylindrical mirror 11.

The positioning groove 4 is structured such that the horizontal cylindrical mirror 11 can slide on the positioning groove 4 to adjust the position.
Example 2
In configuration i, the positioning edges 9 of the upper edges of the two sides of the positioning groove 4 are symmetrical to one another.
As shown in fig. 3 and 4, the positioning grooves 4 with symmetrical structures are adopted, so that the processing and molding are facilitated, and when the horizontal cylindrical mirror 11 is adjusted, two sides can move symmetrically, and the stability in the debugging process is ensured. After the horizontal cylindrical mirror 11 is placed in the positioning groove 4, the two end surface circumferences of the horizontal cylindrical mirror 11 are respectively in point contact with the two positioning edges 9 of the positioning groove 4, and at the moment, four points on the two end surface circumferences of the horizontal cylindrical mirror 11 are in contact with the positioning edges 9; when the horizontal cylindrical mirror 11 is debugged, the horizontal cylindrical mirror 11 slides along the axial direction of the horizontal cylindrical mirror, and the included angle of 90 degrees between the axis of the horizontal cylindrical mirror 11 and the optical axis of the laser collimation point light source 13 can be accurately adjusted, so that the linear precision reaches a zero-error state.
