[0029] The longitudinal drive 4 is used for driving the laser emitter 8 to rotate longitudinally along the axis of the drive rod 5; the transverse drive 9 drives the laser emitter 8 to overturn transversely through the drive rope 12.

[0030] The drive rod 5 is driven by the longitudinal drive 4, the mounting seat 7 is driven to rotate, the laser emitter 8 is longitudinally adjusted, the winding roller 10 is driven by the transverse drive 9, the posture of the mounting seat 7 is changed by winding and unwinding the drive rope 12, and the transverse angle of the laser emitter 8 is adjusted; the effect of accurately and flexibly adjusting the angle of the laser emitter 8 is realized, the laser emitter 8 can quickly and accurately aim at different direction targets, and the precision and efficiency of the laser operation of the unmanned aerial vehicle are greatly improved.

[0031] Specifically, in the embodiment, as Figure 1 and Figure 2As shown, the longitudinal drive 4 and the transverse drive 9 both adopt motors. The fixed plate 1 is provided with a limiting cylinder 3. The bottom of the fixed plate 1 is fixedly provided with the longitudinal drive 4, the output end of which is connected with the driving rod 5, and the driving rod 5 is rotatably connected to the limiting cylinder 3, thereby ensuring the stability of the driving rod 5 in the rotating process, so that it can only rotate around its own axis inside the limiting cylinder 3.

[0032] In the embodiment, the upper end of the driving rod 5 is formed with a Y-shaped branch arm 6, the mounting seat 7 is rotatably connected between the two branch arms 6, and a notch is arranged at the upper end of the driving rod 5. The transverse drive 9 is fixedly arranged on the side of one of the branch arms 6, the winding roller 10 is connected to the output end of the transverse drive 9 and passes through the branch arm 6 and is arranged on the notch, and the driving rope 12 is wound on the winding roller 10 arranged in the notch.

[0033] When the longitudinal angle of the laser emitter 8 needs to be adjusted, the longitudinal drive 4 starts to work, the power output by the longitudinal drive 4 drives the driving rod 5 to rotate inside the limiting cylinder 3, thereby driving the branch arm 6 to rotate around the longitudinal axis, further driving the mounting seat 7 to change the longitudinal angle, so as to realize the adjustment of the longitudinal angle of the laser emitter 8 and meet the needs of longitudinal scanning or irradiation of the target in different task scenarios.

[0034] When the transverse angle of the laser emitter 8 needs to be adjusted, since the output end of the transverse drive 9 is fixedly connected with the winding roller 10, the winding roller 10 starts to rotate after the transverse drive 9 is started, thereby winding or unwinding the driving rope 12.

The side wall of the limiting cylinder 3 is also provided with a second damping plug 13 screwed thereon, one end of which abuts against the side wall of the drive rod 5, and the other end is also provided with a slot 15 or a cross slot 16. By adjusting the close degree of one end of the second damping plug 13 to the drive rod 5, the pre-tightening force adjustment of the rotation of the drive rod 5 is realized, and then the stability, accuracy and flexibility of the drive rod 5 driven by the longitudinal drive 4 are adjusted.
