[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1 Reference Figure 1-4The bracket shown in FIG1 is used for measuring verticality of close-range photography, and includes a frame body 1 and a horizontal adjustment seat 2. The horizontal adjustment seat 2 is arranged on the frame body 1. It should be noted that, in this embodiment, the installation method of the horizontal adjustment seat 2 can refer to the technical content adopted in the bracket for measuring verticality of close-range photography disclosed in the Chinese patent publication number CN214502390U in the prior art, which will not be repeated here. Four side plates 3 are fixedly installed on the outer wall of the peripheral side of the frame body 1, and a transmission cavity is opened in each of the four side plates 3. The frame body 1 is provided with a plurality of side plates 3. Four slide grooves are provided at the bottom, and screw rods 4 are rotatably installed on the relative inner walls of the four slide grooves and the four transmission chambers, and sliders 5 are threadedly installed on the four screw rods 4. Support columns 6 are rotatably installed at the bottoms of the four sliders 5, and base plates 7 are rotatably installed at the other ends of the four support columns 6. Grading control components are provided in the four transmission chambers, and the four graded control components are respectively adapted to the four screw rods 4. Limiting holes are provided on the side inner walls of the four transmission chambers, and limiting components are provided in the four limiting holes. A level ruler 18 is provided on the top of the frame 1.

[0024] With the above structure, when in use, first fix the base plate 7 on the ground, and then adjust the frame 1 to the initial level according to the structure measured by the level ruler 18. When adjusting, first release the limit of the screw rod 4 by the limit assembly, and then drive the screw rod 4 to rotate through the graded control assembly, 1 so that the slider 5 is driven to move away from the axis or close to the axis under the action of the thread, so that the angle of the frame 1 is adjusted by the action of the support column 6 until the level ruler 18 is in a horizontal state.

[0025] Example 2

[0026] like Figure 1 As shown, fixing holes are provided on the tops of the four base plates 7, and latches 8 are provided in the four fixing holes. The advantage of this arrangement is that the base plates 7 can be quickly positioned by providing multiple latches 8.

[0027] Specifically, when the device needs to be placed, multiple pins 8 can be inserted into the ground to achieve the fixing function of the bottom plate 7, thereby quickly fixing the device.

[0028] Example 3

[0029] like Figure 5 As shown, the graded control component includes a large gear 9, and a first rotating shaft is rotatably installed on the side inner wall of the transmission cavity. The large gear 9 is fixedly sleeved on the first rotating shaft, and a rotating gear 10 is fixedly sleeved on the screw 4. The large gear 9 is meshed with the rotating gear 10 and installed. The other end of the first rotating shaft extends to the outside of the side plate 3 and is provided with a large knob 11. The advantage of this arrangement is that through the setting of the large gear 9, the rotating gear 10 can be driven to rotate rapidly, thereby driving the screw 4 to rotate synchronously and rapidly.

[0030] Specifically, when the slider 5 needs to be adjusted quickly, the large knob 11 is rotated to drive the large gear 9 to engage with the rotating gear 10, thereby driving the rotating gear 10 and the screw 4 to rotate synchronously and quickly, thereby quickly adjusting the position of the slider 5, and the adjustment speed is fast.

[0031] like Figure 5 As shown, the graded control component also includes a pinion 12, and a second rotating shaft is rotatably installed on the side inner wall of the transmission chamber. The pinion 12 is fixedly sleeved on the second rotating shaft, and the pinion 12 is meshed with the rotating gear 10. The other end of the second rotating shaft extends to the outside of the side plate 3 and is provided with a small knob 13. The advantage of this arrangement is that through the setting of the pinion 12, the rotating gear 10 can be driven to rotate slowly, thereby driving the screw 4 to rotate slowly synchronously.

[0032] Specifically, when fine adjustment of the slider 5 is required, the small knob 13 is rotated to drive the small gear 12 to engage with the rotating gear 10, thereby driving the rotating gear 10 and the screw 4 to rotate slowly and synchronously, thereby slowly adjusting the position of the slider 5 and improving the adjustment accuracy.

[0033] Example 4

[0034] like Figure 5 As shown, the limit assembly includes a sliding shaft 14, which is slidably installed in the limit hole, one end of the sliding shaft 14 extends into the transmission cavity and is fixedly installed with an extrusion plate 15, and the other end of the sliding shaft 14 is provided with an operating block 17, one side of the extrusion plate 15 is provided with an elastic unit, and the other side of the extrusion plate 15 is provided with a friction unit. The advantage of this arrangement is that after the adjustment of the screw 4 is completed, the first rotating shaft is squeezed by the extrusion plate 15, thereby realizing the limiting function thereof, preventing it from rotating arbitrarily and driving the screw 4 to rotate synchronously.

[0035] Specifically, when it is necessary to adjust the position of the slider 5, first pull the operating block 17 to drive the sliding shaft 14 to move horizontally synchronously, and then release the limit of the extrusion plate 15 on the first rotating shaft, so that the staff can turn the large knob 11 or the small knob 13 to adjust the position of the slider 5. After the adjustment operation is completed, release the operating block 17. Through the elastic action of the elastic unit, the extrusion plate 15 can be driven to realize the reset function, thereby realizing the limit function of the first rotating shaft to prevent it from rotating arbitrarily and affecting the horizontal state of the frame 1.

[0036] like Figure 5As shown, the elastic unit includes an extrusion spring 16, which is sleeved on the sliding shaft 14, one end of the extrusion spring 16 is fixedly mounted on the side of the extrusion plate 15, and the other side of the extrusion spring 16 is arranged on the side inner wall of the transmission cavity. The advantage of this arrangement is that through the arrangement of the extrusion spring 16, when the limit on the operating block 17 is released, the operating block 17, the sliding shaft 14, and the extrusion plate 15 can be driven by its elastic action to achieve the reset function.

[0037] Specifically, when the operating block 17 is pulled, the extrusion spring 16 is squeezed, and when the limit is released, the extrusion plate 15 can be driven to achieve a reset function through its elastic action.

[0038] like Figure 5 As shown, the friction unit includes a friction pad, which is arranged on the side of the extrusion plate 15. The advantage of this arrangement is that the friction pad can play a protective role when the extrusion plate 15 squeezes and limits the first rotating shaft.

[0039] Specifically, by providing a friction pad on the side of the extrusion plate 15 , not only the stability can be improved, but also a protective function can be provided to prevent the extrusion plate 15 or the first rotating shaft from being damaged.

[0040] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
