[0035] The laser rangefinder 6 is fixedly connected with a fourth mounting plate 7 on both sides, and the inner thread of the fourth mounting plate 7 is connected with a second bolt 8, and the second bolt 8 is threadedly connected with the steering plate 4. The second bolt 8 is screwed to make the laser rangefinder 6 threadedly connected with the surface of the steering plate 4, so as to install and use the laser rangefinder 6. The rear surface of the electric warning transmitter 1 is provided with a second mounting plate 17, and the rear surface of the current sensor 14 is provided with a third mounting plate 15. The inner parts of the second mounting plate 17 and the third mounting plate 15 are both threadedly connected with a first bolt, and the electric warning transmitter 1 and the current sensor 14 can be installed together in an external device for use by using the first bolt. The laser rangefinder 6 integrates wireless communication through the control of a single-chip microcomputer, realizes multi-party remote monitoring and alarm, and ground operators can timely discover dangerous areas and receive alarm prompts during the lifting process of the mechanical arm, which makes up for the insufficiency that ground operators cannot obtain the safety status near the aerial mechanical arm, and greatly improves safety and reaction speed.

[0036] The front surface of the electric warning transmitter 1 is fixedly connected with a connecting plate 2, and the front surface of the connecting plate 2 is fixedly connected with a mosaic plate 3, and the front surface of the mosaic plate 3 is movably connected with a rotating rod 13 through a bearing. The side surface of the rotating rod 13 is provided with a first rubber seat 16, and the end of the rotating rod 13 away from the mosaic plate 3 is fixedly connected with a steering plate 4. The inside of the steering plate 4 is slidably connected with a mosaic rod 5, and the mosaic rod 5 is mosaic-connected with the mosaic plate 3. The end of the mosaic rod 5 away from the mosaic plate 3 is fixedly connected with a baffle plate 34, and the rear surface of the baffle plate 34 is fixedly connected with a transverse plate 33; the side surface of the transverse plate 33 is provided with a first magnetic block 32. The front surface of the steering plate 4 is fixedly connected with a fixed plate 30, and the front surface of the fixed plate 30 is movably connected with a movable rod 31 through a bearing, and the end of the movable rod 31 away from the fixed plate 30 is fixedly connected with a mosaic seat 35, and the mosaic seat 35 is mosaic-connected with the first magnetic block 32 and the transverse plate 33. The rear surface of the steering plate 4 is fixedly connected with a connection seat 29, and the diameter of the connection seat 29 is larger than the rotating rod 13. The connection seat 29 is provided with a groove 25 inside, and the groove 25 is connected with the rotating rod 13. The connection seat 29 is provided with a second rubber seat 27 inside, and the side surface of the second rubber seat 27 is provided with a fixing block 28, and the fixing block 28 is fitted with the first rubber seat 16, so that the connection seat 29 and the rotating rod 13 are fitted. The front end of the rotating rod 13 can be fitted into the groove 25. When the connection seat 29 is fitted with the rotating rod 13, the fixing block 28 can be fitted with the first rubber seat 16. By using the fitting of the connection seat 29 and the rotating rod 13, the steering plate 4 can drive the laser rangefinder 6 to change its azimuth. When the steering plate 4 rotates, the steering plate 4 can drive the connection seat 29, the second rubber seat 27 and the fixing block 28 to rotate together, so that the fixing block 28 can rub on the surface of the second rubber seat 27. When the azimuth adjustment of the laser rangefinder 6 is completed, the fitting rod 5 can be pushed backward so that the fitting rod 5 can penetrate the steering plate 4 and extend into the interior of the fitting plate 3 to pre-fix the steering plate 4. When the fitting rod 5 is moving, the fitting rod 5 can drive the baffle 34, the cross plate 33 and the first magnetic block 32 to move. When the cross plate 33 and the first magnetic block 32 are moving, the cross plate 33 and the first magnetic block 32 can be fitted into the interior of the fitting seat 35 so that the first magnetic block 32 can attract the inner wall of the fitting seat 35 to fix the fitting rod 5. When the steering plate 4 is rotating, the movable rod 31 and the fitting seat 35 can be used to adjust the azimuth of the fitting seat 35 by using the movement of the movable rod 31 and the fitting seat 35, so that the fitting seat 35 can be adjusted according to the rotation azimuth of the steering plate 4, so that the cross plate 33, the first magnetic block 32 and the fitting seat 35 are more convenient to connect, so that it is convenient to adjust the azimuth of the laser rangefinder 6.

[0037] The lower surface of the steering plate 4 is movably connected to a movable plate 9 through a bearing, and the movable plate 9 is located below the laser rangefinder 6. The upper surface of the movable plate 9 is fixedly connected to a first mounting plate 19. A spring 24 is fixedly connected to the upper surface of the first mounting plate 19, and an end of the spring 24 away from the first mounting plate 19 is fixedly connected to an elastic plate 11. An movable bead 20 is movably connected inside the elastic plate 11, and a support rod 23 is fixedly connected to the upper surface of the movable bead 20, and a wiping seat 22 is fixedly connected to the end of the support rod 23 away from the movable bead 20, and a fluff cloth 21 is provided on the upper surface of the wiping seat 22. Before the laser rangefinder 6 is used, the movable plate 9 is movable so that the movable plate 9 can be placed in parallel to correspond to the ranging probe of the laser rangefinder 6. When the movable plate 9 is placed in parallel, the fluffy cloth 21 can fit the ranging probe of the laser rangefinder 6. The elasticity of the spring 24 is utilized to make the fluffy cloth 21 completely fit the ranging probe. The movable plate 9 is continuously pushed upward so that the first mounting plate 19 and the elastic plate 11 squeeze the spring 24 together, and the movable bead 20 is affected by the squeezing and can move inside the elastic plate 11, so that the wiping seat 22 is affected by the movement of the movable bead 20 and can drive the fluffy cloth 21 to change its angle slightly, so that the fluffy cloth 21 can fit the arc surface of the ranging probe, thereby improving the clarity of the laser rangefinder 6 probe when the laser rangefinder 6 is in use.

[0038] The side surface of the wiring 12 is sleeved with the wire box 10, and the lower surface of the wire box 10 is open. The inside of the wire box 10 is movably connected with a rotating plate 36 through a bearing, and the lower surface of the rotating plate 36 is fixedly connected with a connecting rod 40, and the side surface of the connecting rod 40 is sleeved with a winding plate 37. The end of the connecting rod 40 away from the rotating plate 36 is fixedly connected with a pinching block 39, and the lower surface of the wire box 10 is provided with a second magnetic block 26, and the lower surface of the second magnetic block 26 is provided with a cover plate 38, and the cover plate 38 is slidably connected with the wiring 12. When the device is in use, the excess wiring 12 can be extended into the interior of the wire box 10. Since the diameter of the winding plate 37 decreases from top to bottom, pinching the pinching block 39 drives the connecting rod 40 to rotate, and the connecting rod 40 can drive the winding plate 37 to rotate, so that the winding plate 37 can reel in the excess wiring 12. When the wiring 12 is rolled up, the cover 38 can be pushed upward so that the cover 38 can slide on the surface of the wiring 12. The movement of the cover 38 allows it to fit and attract the second magnetic block 26 to fix the cover 38, so that the wire box 10 can store excess wiring 12 to prevent the wiring 12 from getting tangled during use.

[0039] When in use, the second bolt 8 is screwed to thread the laser rangefinder 6 with the surface of the steering plate 4 to install the laser rangefinder 6. The steering plate 4 can drive the laser rangefinder 6 to change its orientation by engaging the connecting seat 29 with the rotating rod 13. When the steering plate 4 rotates, the connecting seat 29, the second rubber seat 27 and the fixing block 28 can rotate together, so that the fixing block 28 can rub against the surface of the second rubber seat 27. When the azimuth adjustment of the laser rangefinder 6 is completed, the engaging rod 5 can be pushed backward so that the engaging rod 5 can penetrate the steering plate 4 and extend into the interior of the engaging plate 3 to pre-fix the steering plate 4. When the engaging rod 5 is moving, the engaging rod 5 can drive the baffle 34, the cross plate 33 and the first magnetic block 32 to move. When the cross plate 33 and the first magnetic block 32 are moving, the cross plate 33 and the first magnetic block 32 can be engaged with the interior of the engaging seat 35 so that the first magnetic block 32 can attract the inner wall of the engaging seat 35 to fix the engaging rod 5. When the steering plate 4 is rotating, the movable rod 31 and the engaging seat 35 can be used to adjust the azimuth of the engaging seat 35 by using the movement of the movable rod 31 and the engaging seat 35, so that the engaging seat 35 can be adjusted according to the rotation azimuth of the steering plate 4, so that it is convenient to adjust the azimuth of the laser rangefinder 6. By utilizing the movement of the movable plate 9, the movable plate 9 can be placed in parallel to correspond to the ranging probe of the laser rangefinder 6. When the movable plate 9 is placed in parallel, the fluffy cloth 21 can fit the ranging probe of the laser rangefinder 6. By utilizing the elasticity of the spring 24, the fluffy cloth 21 can completely fit the ranging probe. The movable plate 9 is continuously pushed upward, so that the first mounting plate 19 and the elastic plate 11 squeeze the spring 24 together, and the movable bead 20 is affected by the squeezing and can move inside the elastic plate 11, so that the wiping seat 22 is affected by the movement of the movable bead 20 and can drive the fluffy cloth 21 to change its angle slightly, so that the fluffy cloth 21 can fit the arc surface of the ranging probe to test the ranging probe, and extend the excess wiring 12 into the interior of the wire take-up box 10. As the diameter of the winding plate 37 decreases from top to bottom, the pinch block 39 drives the connecting rod 40 to rotate, and the connecting rod 40 can drive the winding plate 37 to rotate, so that the winding plate 37 can reel in the excess wiring 12. When the wiring 12 is reeled in, the cover plate 38 can be pushed upward so that the cover plate 38 can slide on the surface of the wiring 12. The movement of the cover plate 38 allows it to fit and attract the second magnetic block 26 to fix the cover plate 38, so that the wire box 10 can store the excess wiring 12.

[0040] It can be seen from the above description that compared with the prior art, the beneficial effects brought by the embodiments of the present invention are:

[0041] First, the device realizes the flexible adjustment of the laser rangefinder's position through the interlocking design of the connecting seat and the rotating rod. When the steering plate rotates, it can drive the relevant components to move in coordination. At the same time, the magnetic fixing mechanism of the interlocking rod and the interlocking seat ensures the stability of the laser rangefinder after adjustment. In addition, the interlocking seat can also be adaptively adjusted according to the rotation position of the steering plate, making the entire adjustment process more convenient and efficient.

[0042] Secondly, before the laser rangefinder is used, the device effectively improves the clarity of the distance probe through the design of the movable plate and the fluffy cloth. The movable plate can be placed parallel to the corresponding position of the distance probe, and the elasticity of the spring can be used to make the fluffy cloth fit the probe completely. Through the cooperation of the movable beads and the elastic plate, the fluffy cloth can be slightly adjusted according to the arc surface of the probe, thereby ensuring that the laser rangefinder has higher accuracy and reliability when in use.

[0043] In addition, the present invention is also equipped with a wire take-up box design for storing excess wires. The special diameter design of the wire reel makes it easier to reel in wires, while the fit and attraction mechanism between the cover plate and the second magnetic block ensures the airtightness and stability of the wire take-up box. This design effectively prevents the wires from getting tangled during use, and improves the overall practicality and aesthetics of the device.
