Solution Approach 1:

The patent introduces rotation adjustment screws and swing adjustment screws that enable dynamic adjustment of the laser emitter's orientation. The rotation adjustment screws allow adjustment around the optical axis, while the swing adjustment screws allow adjustment in the vertical plane, transforming a static structure into a dynamically adjustable one without excessive complexity

Inventive Principle:

AI summary

Embodiments of the present invention disclose a two-line laser emitter. The two-line laser emitter includes a housing, a laser emitter base mounted inside the housing, an elastic clamping member, a laser emitter and a pair of rotation adjustment screws. The laser emitter base has a laser emitter mounting hole. The elastic clamping member is mounted in the laser emitter mounting hole. The laser emitter is mounted in the laser emitter mounting hole, and one end of the laser emitter is inserted into the elastic clamping member. The laser emitter is configured to emit a planar ray of light out of the housing. A pair of rotation adjustment screws are disposed in the laser emitter base and located on the same side of a central axial plane of the laser emitter. The pair of rotation adjustment screws abut against a side wall of the laser emitter in opposite directions on the same straight line. Each of the rotation adjustment screws is adjustable to slightly adjust a rotation angle of the planar ray of light emitted by the laser emitter. By means of the structure described above, emission angles of different laser emitters can be adjusted by using the two-line laser emitter, thus helping users perform self-calibration.
