[0036] Referring to Figure 3 and Figure 5The clamping mechanism 4 comprises two sliding blocks 44, which are designed to have good sliding ability, so that smooth sliding can be achieved on the top of the support plate 3. The outer part of the two sliding blocks 44 is slidingly connected to the top of the support plate 3. The top of each sliding block 44 is fixedly connected to a clamping frame 41. The clamping frame 41 is driven to slide by the sliding block 44, so that different light source plates can be positioned. The adjacent side of each clamping frame 41 is fixedly connected to a fixed pad 45, which is made of soft material. The fixed pad 45 can clamp the backlight. The adjacent side of each clamping frame 41, i.e. the outer side away from the fixed pad 45, is fixedly connected to two guide columns 42, which are designed to have good guiding ability. The outer part of each guide column 42 is sleeved with a spring 43. When the sliding block 44 is stretched, the spring 43 can be stretched. When the sliding block 44 is released, the spring 43 can automatically reset. At the same time, the guide column 42 can prevent the spring 43 from moving when stretched and reset. The opposite side of the outer part of each clamping frame 41 is slidingly connected to a sliding column 46, which is designed to have good sliding ability. The outer side of each sliding column 46 is fixedly connected to a pulling plate 47. When the sliding column 46 slides, the pulling plate 47 can slide. When the pulling plate 47 is pulled, the two sliding columns 46 on the same side can slide together. The outer front side of each clamping frame 41 is slidingly connected to a baffle 48, which is designed to have good sliding ability. When the sliding column 46 slides inside the baffle 48, the baffle 48 can have different sliding sizes to be fixed. The outer front side of each baffle 48 is fixedly connected to a limiting plate 49, which is designed on the outer front side of the base 1. The limiting plate 49 can prevent the baffle 48 from falling off when the angle is adjusted. The outer part of each sliding column 46 penetrates the inner part of the clamping frame 41 and the baffle 48 in sequence.

[0037] Working principle: when the position of the backlight needs to be adjusted, first of all, the horizontal position and angle adjustment of the supporting plate 3 is realized through the adjusting mechanism 2. The sliding plate 21 slides in the sliding groove 23 on the top of the base 1, thereby driving the supporting plate 3 to move horizontally. At the same time, the rotating ability of the rotating column 22 enables the supporting plate 3 to be adjusted in angle. When the sliding plate 21 slides, the rotation of the rotating plate 29 can drive the supporting plate 3 to change in angle, thereby realizing the multi-directional position adjustment of the backlight. During the position adjustment of the supporting plate 3, the sliding block 25 slides in the sliding groove 24 on the top of the base 1, and the pressing plate 27 rotates inside the sliding block 25, so that the clamping block 28 can be clamped in the internal groove of the supporting column 26. Through the sliding of the sliding block 25 and the rotation of the rotating plate 29, the angle adjustment of the supporting plate 3 is further realized, which ensures that the backlight can be accurately adjusted to the required position. At the same time, the air cylinder 52 of the fitting mechanism 5 is supported by the supporting block 51 to be horizontally stretched and contracted, thereby driving the fitting block 53 to move. The fitting block 53 is connected to the backlight, which can be connected to the test of the backlight, and ensure that the backlight is closely fitted with the target part during the adjustment process, thereby improving the accuracy and stability of the adjustment;

[0038] When the backlight needs to be clamped and fixed, first of all, the clamping frame 41 is pulled to both sides, and at the same time the spring 43 outside the guide column 42 is stretched. The spring 43 can store elastic potential energy during the stretching process. When the sliding column 46 slides outward, it enables the baffle 48 to slide. At this time, the backlight can be placed on the fixing pad 45 between the two clamping frames 41. The soft material of the fixing pad 45 can be closely fitted with the surface of the backlight, which plays a role in buffering and protection. When the backlight is placed in place, the spring 43 is automatically retracted after the clamping frame 41 is loosened, which drives the guide column 42 to slide inward, so that the clamping frame 41 moves inward, and the fixing pad 45 exerts clamping force on the backlight, thereby firmly clamping the backlight between the two clamping frames 41. At the same time, the baffle 48 also slides inward under the fixation of the sliding column 46, and the sliding column 46 can fix the baffle 48. Through the distance limitation of the limiting plate 49, the backlight is prevented from falling off during the angle adjustment.

[0039] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, as long as it is within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present application.
