[0024] An adjusting device is provided on the front side of the threaded block 7 , and the adjusting device includes a fixing block 8 , and a back side of the fixing block 8 is fixedly connected to the front side of the threaded block 7 .

[0025] A support frame 81 is fixedly connected to the front of the fixed block 8, and a rotating rod 82 is installed on the inner walls of both ends of the support frame 81 through bearings. Both ends of the rotating rod 82 are fixedly connected to an arc-shaped adjustment block 83. A worm gear 84 is fixedly sleeved on the outer surface of the rotating rod 82. A second servo motor 85 is fixedly installed on the upper surface of the fixed block 8. A worm 86 is fixedly installed on the output shaft of the second servo motor 85 through a coupling. The outer surface of the worm 86 is meshed with the tooth surface of the worm gear 84. The rotation of the worm 86 drives the rotating rod 82 to rotate through the meshing worm gear 84. The rotation of the rotating rod 82 drives the arc-shaped adjustment block 83 to adjust the elevation angle. The outer surface of the arc-shaped adjustment block 83 is fixedly sleeved with an arc-shaped outer gear ring 87, and the upper surface of the arc-shaped adjustment block 83 is provided with an arc-shaped limiting groove 88.

[0026] The inner wall of the arc-shaped limit slide 88 is slidably connected with an arc-shaped slider 89, and the upper surface of the arc-shaped slider 89 is fixedly connected with a mounting plate 810, and the upper surface of the mounting plate 810 is fixedly mounted with a lighting lamp body 811. Through the cooperation of the arc-shaped limit slide 88 and the arc-shaped slider 89, the lighting lamp body 811 can be stably moved and adjusted. The front of the mounting plate 810 is fixedly connected with an L-shaped driving block 812, and the inner wall of the L-shaped driving block 812 is fixedly mounted with a third servo motor 813. The output shaft of the third servo motor 813 is fixedly installed with a rotating shaft 814 through a coupling. A gear 815 is fixedly sleeved on the outer surface of one end of the rotating shaft 814. The tooth surface of the gear 815 is meshed with the tooth surface of the arc-shaped outer gear ring 87. The third servo motor 813 drives the rotating shaft 814 to rotate. The rotation of the rotating shaft 814 drives the gear 815 to rotate. The rotation of the gear 815 drives the mounting plate 810 to perform circular movement adjustment through the meshing arc-shaped outer gear ring 87 and the L-shaped driving block 812.

[0027] By setting up the adjustment device, the height of the lighting lamp body 811 can be automatically adjusted, and the left and right angles and elevation angles of the lighting lamp body 811 can be automatically adjusted. The automated adjustment reduces the difficulty of adjustment and avoids safety hazards during climbing.

[0028] Working principle: Step 1, when adjusting the height, the first servo motor 5 drives the screw rod 6 to rotate clockwise, and the rotation of the screw rod 6 limits the thread block 7 through the movable groove 4, so that the thread block 7 drives the lighting lamp body 811 to move upward through the fixed block 8 and the support frame 81;

[0029] Step 2: When adjusting the light left or right, start the third servo motor 813 to drive the shaft 814 to rotate clockwise. The rotation of the shaft 814 drives the gear 815 to rotate. The rotation of the gear 815 drives the mounting plate 810 to move in a circular manner through the meshing arc-shaped outer gear ring 87. The arc-shaped limiting slide groove 88 cooperates with the arc-shaped slider 89 to make the lighting lamp body 811 move stably and adjust. On the contrary, when the shaft 814 rotates counterclockwise, it moves in the opposite direction.

[0030] Step three, when adjusting the elevation angle, start the second servo motor 85 to drive the worm 86 to rotate clockwise. The rotation of the worm 86 drives the rotating rod 82 to rotate through the meshing worm wheel 84. The rotation of the rotating rod 82 drives the lighting lamp body 811 to adjust the elevation angle through the arc-shaped adjustment block 83. Conversely, when the worm 86 rotates counterclockwise, it is adjusted in the opposite direction.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
