[0028] Working principle of Embodiment 2:

[0029] By sequentially providing the lens mounting groove 6 and the element mounting groove 5 at the upper end of the sleeve 2, the optical diffraction component 9 and the collimating lens 8 are integrally arranged in the sleeve 2, and there is no need to install an external bracket to place the optical diffraction component 9 and the collimating lens 8, which improves the integration of the optical diffraction component 9 and the collimating lens 8.

[0030] Preferably, as Figure 3 shown, a plurality of first grasping grooves 10 are provided at the bottom of the sleeve 2, and a plurality of second grasping grooves 11 are provided at the bottom of the laser emitter 4. The number and positions of the first grasping grooves 10 and the second grasping grooves 11 are the same, and the first grasping grooves 10 are located outside the second grasping grooves 11. The multi-axis adjustment mechanism connects the laser emitter 4 by clamping the first grasping grooves 10 and the second grasping grooves 11 in sequence through the clamping member.

[0031] Specifically, in this embodiment, the number of both the first grasping grooves 10 and the second grasping grooves 11 is three, and they are evenly distributed. By providing the first grasping grooves 10 and the second grasping grooves 11, it is convenient for the clamping member of the multi-axis adjustment mechanism to clamp and fix the laser emitter 4, improving the structural connection stability.

[0032] Preferably, glue injection openings 12 are provided on both sides of the sleeve 2. After the multi-axis adjustment mechanism is adjusted, an external glue injection component injects glue through the glue injection openings 12 to bond and fix the laser emitter 4 and the sleeve 2.

[0033] Specifically, in this embodiment, by providing the glue injection openings 12 on both sides of the sleeve 2, it is convenient for the external glue injection component to inject glue through the glue injection openings 12, improving the glue injection convenience.

[0034] Preferably, glue injection U-shaped grooves 13 are provided on both sides of the upper end of the sleeve 2. After the multi-axis adjustment mechanism is adjusted, an external glue injection component injects glue through the glue injection U-shaped grooves 13 to bond and fix the laser emitter 4 and the sleeve 2.

[0036] Preferably, as Figure 1 shown, the laser emitter 4 includes a metal case 41, a launching base 42, a plurality of laser components 43 and a plurality of laser pins 44.

[0039] Working principle of Embodiment 3:

[0040] Since the grounded pin in the laser pin 44 has a downward soldering protrusion, in the prior art, in order to ensure the smoothness of the connection between the laser emitter 4 and the circuit board, a larger hole needs to be opened on the circuit board. However, this method will cause the pin to wobble after being inserted into the larger hole, resulting in low connection stability of the laser emitter 4. In this embodiment, after the height of the bottom end of the launching base 42 is higher than the height of the bottom end of the sleeve 2, the laser emitter 4 is fixed to the sleeve 2, so that it is not necessary to open a larger hole on the circuit board, and only a hole adapted to the pin aperture needs to be opened. Therefore, after each laser pin 44 is plugged into the circuit board, it will not wobble, thereby improving the connection stability between the laser emitter 4 and the circuit board.

All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
