Technical Field

[0001] The invention relates to the field of laser pointing instruments, in particular to a laser pointing instrument. Background Art

[0002] Laser pointers are mainly used for laying out, positioning, pointing, and providing collimation lines in mining, railway tunnels, municipal construction, subway projects, large-scale water diversion projects, construction, and pipeline laying. Its working principle is to use a low-power semiconductor laser to emit laser light, which is converged through an optical system to become a highly collimated laser beam, and the pointing work is completed through horizontal and vertical fine-tuning. The laser pointer is mainly composed of a laser, an optical system, a power supply, and an installation and adjustment mechanism. Among them, the laser usually uses a helium-neon gas laser, which emits an orange-red visible beam.

[0003] When the laser pointer is idle, the laser transmitting head of the laser pointer is idle, especially in a dusty working area, and the inside is easily contaminated with dust. Dust particles may cause the laser to scatter or refract during the emission process, resulting in deviations in the direction of the laser beam, thereby reducing the pointing accuracy of the laser pointer; dust will block the emission of part of the laser and weaken the intensity of the laser.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention facilitates the adjustment of the angle of the laser irradiation of the pointing instrument body by holding the handle. Since the adjustment ball at the bottom of the pointing instrument body is movably arranged inside the mounting seat, the surface of the mounting seat is covered by a fixed cover.

[0021] Working principle: when installing the device, a screw hole is provided on the bottom surface of the base 9, and the top of the support frame is screwed inside the screw hole; so that the bottom of the pointing instrument body 1 is supported and fixed by the support frame. During specific operation, the external switch of the pointing instrument body 1 is started, and the laser gun rod 10 at the end of the pointing instrument body 1 emits a laser. By holding the handle 3, it is convenient to adjust the angle of the laser irradiated by the pointing instrument body 1. Since the adjustment ball 6 at the bottom of the pointing instrument body 1 is movably arranged inside the mounting seat 8, the surface of the mounting seat 8 is covered by the fixing cover 7. In this way, the adjustment ball 6 is installed by the fixing cover 7 and the mounting seat 8. The setting of the fixing cover 7 can increase the friction between the adjustment ball 6 and the mounting seat 8, so as to ensure the stability of the pointing instrument body 1 when it is stationary. After the angle is adjusted, it will not loosen. The surface of the pointing instrument body 1 is positioned and installed with a level bubble 5 through the positioning groove 2 and the positioning seat 4.
