[0032] Reference Figure 1 - Figure 3 The lower surface of the hollow column 31 is fixedly connected to the upper surface of the base 1, and the base 1 provides support for the hollow column 31. The left surface of the support plate 41 is fixedly connected to the right surface of the connecting column 32. The base 1, the hollow column 31, the connecting column 32, the support plate 41, and the slide plate 42 are arranged in two groups. The two groups of base 1, hollow column 31, connecting column 32, support plate 41, and slide plate 42 are arranged symmetrically with respect to the center line of the positioning plate 43, which can keep the positioning plate 43 in the center position. The lower surface of the left end of the connecting rod 44 is hinged to the upper surface of the support plate 41. When the connecting rod 44 rotates, it can drive the support plate 41 to open to both sides, and the slide plate 42 will extend from the support plate 41, thereby increasing the width of the device. Similarly, when the connecting rod 44 rotates in the opposite direction, it will drive the support plates 41 on both sides to come closer, so that the slide plate 42 is retracted into the support plate 41, shortening the width of the overall device.

[0033] Reference Figure 1 - Figure 3 The adjustment assembly also includes a worm 47, a handle 48 is fixedly connected to the front surface of the worm 47, and rotating the handle 48 can drive the worm 47 to rotate, and the inner wall of the bottom end of the positioning plate 43 is rotatably connected to a worm wheel 49.

The handle 48 passes through and is rotatably connected to the front surface of the positioning plate 43 for easy gripping. The upper surface of the worm wheel 49 is fixedly connected to the lower surface of the round block 46, and the worm wheel 49 can drive the round block 46 to rotate when it rotates.

[0035] Reference Figure 1 - Figure 3 The lifting assembly also includes a rubber pad 35. A valve core 34 is provided on the left surface of the left hollow column 31. A one-way valve 33 is provided on the left surface of the left hollow column 31. A ventilation hole 301 is provided on the right surface of the right hollow column 31. The valve core 34 and the one-way valve 33 are prior art and can be implemented by technicians in this field. Since they are prior art, they will not be described in detail in this case. In the utility model, external air can flow into the hollow column 31 from the one-way valve 33, and the air in the hollow column 31 cannot be discharged from the one-way valve 33. A valve nozzle is provided on the valve core 34. When the valve nozzle is no longer pressed, air cannot flow from the valve core 34.

[0036] Reference Figure 1 - Figure 3 The rubber pad 35 piston is connected to the inner wall of the hollow column 31 and slides up and down. When the rubber pad 35 slides upward, negative pressure will be generated in the hollow column 31, so the external air will be sucked in from the one-way valve 33. When the rubber pad 35 stops moving, the gravity of the rubber pad 35 is downward, and the gas inside the hollow column 31 cannot be discharged, so the device will maintain its current height due to its own gravity. The upper surface of the rubber pad 35 is fixedly connected to the lower surface of the connecting column 32, and the one-way valve 33 is located directly below the valve core 34.

[0037] Reference Figure 1 , Figure 4 The displacement assembly includes a slider 61, the inner wall of the slider 61 is elastically connected to a block 62 via a compression spring 63, and a slot 601 is provided on the lower surface of the positioning plate 43, and the slider 61 can be limited by the cooperation of the slot 601 and the block 62.

[0038] Reference Figure 1 , Figure 4 The slider 61 is slidably connected to the lower surface of the positioning plate 43 and slides horizontally. The block 62 is set to an L shape. The front end of the block 62 passes through and is slidably connected to the front surface of the slider 61 and can be toggled. The block 62 passes through and is slidably connected to the upper surface of the slider 61. One end of the compression spring 63 is fixedly connected to the lower surface of the block 62, and the other end of the compression spring 63 is fixedly connected to the inner wall of the bottom end of the slider 61. When the block 62 moves downward, it will squeeze the compression spring 63 to generate a reaction force. The block 62 is inserted into the inner wall of the slot 601. When the block 62 moves downward, it will also disengage from the slot 601 to release the limit. The upper surface of the pan-tilt 5 is set on the lower surface of the slider 61. When the slider 61 slides, it will drive the pan-tilt 5 and the hyperspectral camera to slide synchronously.

[0039] Working principle: When the device is used, the hyperspectral camera is first installed on the gimbal 5, and then the width and height of the device are adjusted as needed. When adjusting the height of the device, the connecting column 32 is moved upward to drive the rubber pad 35 to move upward. The rubber pad 35 moving upward will suck the external air from the ventilation hole 301 into the hollow column 31 at the right position. The rubber pad 35 moving upward will also suck the external air from the rubber pad 35 into the hollow column 31 at the left position. The connecting column 32 moving upward will also drive the adjustment component, the displacement component and the gimbal 5 to move upward. When moving to a suitable height, the connecting column 32 and the rubber pad 35. The adjustment component, the displacement component and the gimbal 5 will squeeze the air inside the hollow column 31 downward under the influence of gravity. However, since the air inside the hollow column 31 cannot be discharged, the device will maintain its current height. If the device needs to be lowered, press the valve nozzle on the valve core 34. The air in the hollow column 31 on the left can be discharged from the valve core 34, and the air in the hollow column 31 on the right can be discharged from the ventilation hole 301. The connecting column 32, the rubber pad 35, the adjustment component, the displacement component and the gimbal 5 will move downward. When adjusted to a suitable height, release the valve nozzle and the height of the device will be stabilized.

[0040] If the width of the device needs to be adjusted, just grasp the handle 48 and rotate it to drive the worm 47 to rotate. The rotating worm 47 will drive the worm wheel 49 and the round block 46 to rotate. The rotating round block 46 will drive the fixed rod 45 to move. The moving fixed rod 45 will squeeze the connecting rod 44 to rotate the connecting rod 44. The rotating connecting rod 44 will push the support plates 41 on both sides to both sides, and the width of the device will increase. Similarly, grasping the handle 48 and rotating it in the opposite direction can drive the worm 47, the worm wheel 49 and the round block 46 to rotate in the opposite direction. The round block 46 rotating in the opposite direction will drive the fixed rod 45 to move in the opposite direction. The fixed rod 45 moving in the opposite direction will squeeze the connecting rod 44 to rotate the connecting rod 44 in the opposite direction. The connecting rod 44 rotating in the opposite direction will pull the support plates 41 on both sides to make them close together, and the width of the device will become smaller. When the appropriate width is adjusted, release the handle 48 to maintain stability.

[0041] During the use of the device, if it is necessary to fine-tune the position of the hyperspectral camera, first push the block 62 downward. The block 62 moving downward will squeeze the compression spring 63 to generate a reaction force, and the block 62 moving downward will also disengage from the slot 601 to release the limit on the slider 61. Then move the slider 61 horizontally to drive the pan-tilt head 5 and the hyperspectral camera to move. When it moves to a suitable position, release the block 62. The reaction force of the compression spring 63 will push the block 62 upward so that the block 62 and another slot 601 are plugged into each other to form a limit.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
