The sides of the two movable plates 17 close to each other are fixedly connected with a clamping plate 18 and a tooth plate 14, and the two clamping plates 18 are movably clamped in the corresponding clamping grooves 15 respectively, and the movable plate 17 on the left side is threadedly sleeved on the outer side of the threaded rod 9, and the gear 13 is meshed with the two tooth plates 14 to push the slider 3 backward so that the slider 3 slides into the slide groove 8 When it is fully slid in, the card plate 18 is aligned with the card slot 15, and the threaded rod 9 is rotated. The threaded rod 9 drives the movable plate 17 on the left to move inward, and the movable plate 17 drives the toothed plate 14 on the left to move right. The toothed plate 14 on the left drives the gear 13 to rotate clockwise, and the gear 13 drives the toothed plate 14 on the right and the movable plate 17 to move left, thereby driving the two movable plates 17 and the card plate 18 to approach each other. The two card plates 18 are close to each other and are connected in the corresponding card slots 15, so that the slider 3 and the surveying and mapping device body 6 can be installed and fixed. When disassembling and maintenance, the threaded rod 9 is rotated in the opposite direction, so that the two movable plates 17 and the card plate 18 move away from each other and disengage from the card slot 15, and then the slider 3 is not fixed. At this time, the slider 3 and the surveying and mapping device body 6 can be pulled out.

[0025] In the utility model, two guide rods 19 are fixedly connected to the inner walls on both sides of the groove 16, and the two movable plates 17 are respectively slidably sleeved on the outer sides of the corresponding two guide rods 19. A rectangular opening is opened between the groove 16 and the cavity 12, and the two tooth plates 14 are respectively slidably sleeved in the corresponding rectangular openings and are both slidably sleeved in the cavity 12, so as to facilitate the guiding and limiting of the movable plate 17 and the tooth plate 14, so that their movement is more stable and smooth.

[0026] In the present invention, one end of the threaded rod 9 extends to the outside of the mounting seat 2 and is fixedly connected to a hand wheel 10 to facilitate the rotation of the threaded rod 9 .

The screw 11 is threadedly sleeved in the thread groove 20. Through the arrangement of the screw 11 and the thread groove 20, the handwheel 10 can be locked to avoid vibration of the drone body 1 during flight, which causes the handwheel 10 to deflect and causes the clamping plate 18 to be unable to firmly lock the slider 3, thereby further improving the firmness of the fixation.

[0028] In the utility model, the surveying and mapping angle adjustment component includes an upper motor 4 fixedly connected to the slider 3, a mounting frame 5 is fixedly connected to the output shaft of the upper motor 4, a lower motor 7 is fixedly connected to one side of the mounting frame 5, a surveying and mapping device body 6 is fixedly connected to the output shaft of the lower motor 7, and a rotating shaft is rotatably connected to the inner walls on both sides of the mounting frame 5. The surveying and mapping device body 6 is fixedly connected between the two rotating shafts, and the output shaft of the lower motor 7 is fixedly connected to one end of the corresponding rotating shaft. The upper motor 4 drives the rotation of the mounting frame 5, and then the surveying and mapping azimuth of the surveying and mapping device body 6 can be adjusted. The lower motor 7 drives the rotation of the rotating shaft and the surveying and mapping device body 6, and then the inclination angle of the surveying and mapping device body 6 can be adjusted, so that it can perform better surveying and mapping.

[0029] When the slider 3 is fully inserted, the clamping plate 18 is aligned with the clamping groove 15, and the threaded rod 9 is rotated by the hand wheel 10. The threaded rod 9 drives the movable plate 17 on the left to move inward, and the movable plate 17 drives the toothed plate 14 on the left to move right. The toothed plate 14 on the left drives the gear 13 to rotate clockwise, and the gear 13 drives the toothed plate 14 on the right and the movable plate 17 to move left, thereby driving the two movable plates 17 and the clamping plate 18 to approach each other. The two clamping plates 18 are close to each other and are clamped in the corresponding clamping groove 15, so that the slider 3 and the surveying device body 6 can be installed and fixed. When they are fully clamped and fixed, the screw 11 is aligned with the threaded groove 20. Finally, the screw 11 is tightened so that the screw 11 is screwed into the threaded groove 20 to lock the hand wheel 10, avoiding The vibration of the drone body 1 during flight causes the hand wheel 10 to deflect, resulting in the inability of the card plate 18 to firmly lock the slider 3, thereby greatly improving the stability and safety during installation and avoiding the situation of falling off and damage. The upper motor 4 drives the rotation of the mounting frame 5, and the surveying azimuth of the surveying and mapping device body 6 can be adjusted. The lower motor 7 drives the rotation of the rotating shaft and the surveying and mapping device body 6, and the inclination angle of the surveying and mapping device body 6 can be adjusted, so that it can better perform surveying and mapping. When the surveying and mapping device body 6 needs to be disassembled and maintained, the screw 11 is loosened so that the screw 11 is disengaged from the thread groove 20 without fixing the hand wheel 10. At this time, the hand wheel 10 and the threaded rod 9 are rotated in the opposite direction, so that the two moving plates 17 and the card plate 18 are moved away from each other and disengaged from the card groove 15, and the slider 3 is not fixed. At this time, the slider 3 and the surveying and mapping device body 6 can be pulled out.
