For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments so that those skilled in the art may better understand the present invention and implement the present invention, but the embodiments are not limited thereto. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

The laser pointing instrument body 1 is described with reference to fig. 1 and 4, and is composed of the laser pointing instrument body 1 and a fixed base 2. The main body 1 comprises a main shell 16, a laser emitting module 14, a collimating mirror 13, a power switch control module 18, a magnetic conduction column 111 and a switch base 110. The collimating lens 13, the laser emission module 14, the conductive seat 15 and the power supply 17 are sequentially arranged in the main shell 16 from front to tail.

The main housing 16 may be a metal housing, for example, stainless steel is integrally formed, the conductive base 15 is installed in the main housing 16, and the laser emitting module 14 with the teaching completed is installed at the front end of the main housing 16. The laser emission module 14, or called laser emission module, can be aligned and debugged before being installed to ensure that the outer circle of the laser module is coaxial with the laser rays, and then the laser module is connected with the inner hole on the main shell 16 by adopting interference fit to ensure that the concentricity of the laser module and the main shell 16 is kept consistent, and preferably, the concentricity error is less than 0.01 mm.

Preferably, the laser emitting module 14 is limited and fixed by the positioning screw 11. Then, the front cover 12 is mounted on the front end of the main housing 16, thereby achieving the effect of sealing and dust prevention.

In use, the power supply 17 is arranged in the tail direction of the main shell 16, the power supply 17 can be two dry batteries 17 or a mobile power supply, and the like, if two alkaline batteries of 1.5V are adopted as the power supply of the laser direction indicator, the engineering of laying a circuit can be omitted, the production efficiency is greatly improved, and the construction progress is improved. Meanwhile, the safety voltage is used, so that the construction safety is greatly improved.

Switch base 110 is threadably or snappingly connected to the rear of main housing 16. Preferably, when the switch base 110 and the main housing 16 are fixed, the O-ring 19 made of silica gel can be embedded to ensure the overall tightness of the product, thereby achieving the effects of dust prevention, water prevention and explosion prevention.

Fig. 4 shows a perspective view of the body 1 of the laser pointer, but the O-ring (19) is not shown.

The following description will be made with reference to fig. 1 and 5, in which the fixed base 2 is provided with a magnet 23 fitted in the fixed base tail cover 24, the magnetic field direction is oriented by the magnetic pole 111, and the magnetic field signal is received by the power switch control module 18 near the magnetic pole 111 to control the on-off of the circuit. By adopting the structure, the signal is conducted by using the circuit control method, so that the device has the advantages of more reliable stability, simple structure, flexible operation and the like compared with the mechanical method in the prior art, and is also greatly helpful for improving the protection performance of products, such as dust resistance and the like.

As can be seen from fig. 3, in the use state, the fixing base 2 is fixed in a carrier such as a wall or a rock mass 3. Preferably, the colloid filler 4 may be filled after the wall or rock is perforated, so as to facilitate fixing the fixing base 2. When the initial debugging alignment position is adjusted, the position of the fixed base component is adjusted, and the laser pointing instrument main body is inserted only when the laser pointing operation is needed in the follow-up process, namely the lower end 112 of the main shell is installed in the fixed base 2, so that additional debugging is not needed, the debugging time is shortened greatly, the labor is saved, and the production efficiency is improved.

Fig. 2 is a cross-sectional view of the MM view angle in fig. 1, and in combination with the positioning groove 25 identified in fig. 6, the positioning groove 25 on the switch base 110 is matched with the positioning rib (or referred to as a positioning convex strip, not labeled in fig. 2) on the positioning sleeve 22 inside the base main body 21, so that the position of the main body of the laser pointing instrument can be kept unchanged each time, and finally, the accuracy and reliability of repeated positioning of the pointing instrument can be ensured. Those skilled in the art will appreciate that the positioning groove may be disposed on the positioning sleeve, and the positioning rib correspondingly matched with the positioning groove may be disposed on the switch base 110; the positioning groove can also be arranged on the base, and the positioning rib is arranged on the main body. In addition, the positioning groove and the positioning rib can be arranged in a plurality.

In another embodiment of the invention, the laser power of the laser collimation light source can be set to be less than or equal to 2mw, the selected power supply is 2 sections of No. 9 AAAA 1.5V dry batteries as the power supply, and the working current of the laser collimation light source is less than or equal to 30mA. When the laser direction indicator is used, the main body 1 of the laser direction indicator is arranged on the fixed base 2, and as the magnet 23 and the magnetic conduction column 111 are arranged in the fixed base 2, the magnet 23 and the magnetic conduction column 111 generate a magnetic field in a fixed direction, the power switch control module 18 in the main body of the laser direction indicator receives a magnetic field signal and controls the Direct Current (DC) power supply 17 to conduct and work, the laser emission module 14 emits laser, and the laser signal is emitted and directed through the collimating mirror 13; after the use is completed, the main body 1 of the laser direction indicator is pulled out of the fixed base 2, the power switch control module 18 can not receive the magnetic field signal, the DC power supply 17 is controlled to be turned off, the laser module can not emit the laser signal any more, and the laser direction indicator stops working. Therefore, the laser direction indicator can continuously work for more than or equal to 8 hours, and can meet the daily work demands.

In this embodiment, the working voltage of the laser pointing instrument is less than the safety voltage (36V), and the use of the safety voltage also greatly improves the safety of construction.
