[0022] Reference Figure 1-4 A light box bracket that is easy to install includes a base 1, a motor 2 is fixed on the top of the base 1, a screw 3 is fixed on the output shaft of the motor 2, a fixing block 4 is threadedly connected to the screw 3, a first telescopic rod 5 is fixed to the top of both ends of the base 1, the tops of the two first telescopic rods 5 are fixed to the same mounting plate 6, a mounting box 7 is fixed to the top of the base 1, and the inner walls of both ends of the mounting box 7 that are perpendicular to the mounting plate 6 are fixed to second telescopic rods 8, a first trapezoidal plate 9 is fixed to the side where the two second telescopic rods 8 are close to each other, and a second Spring 20, since the motor 2 provides power to make the mounting plate 6 descend and squeeze the first trapezoidal plate 9, the first trapezoidal plate 9 shrinks the second telescopic rod 8, and when the mounting plate 6 slides over the first trapezoidal plate 9, the first trapezoidal plate 9 is rebounded by the second spring 20 and tightly clamps the light box 21. Therefore, the problem that the traditional installation method proposed in the background technology is cumbersome to operate, difficult to install, time-consuming and labor-intensive, and increases the workload of workers is effectively solved, thereby achieving the technical effect of reducing the difficulty of installation, simplifying the installation steps, saving time and effort, and reducing the workload of workers.

[0023] In this embodiment, the interior of the fixing block 4 is provided with a thread compatible with the screw rod 3 , the fixing block 4 is fixedly connected to the mounting plate 6 , a light box 21 is provided on the top of the mounting plate 6 , and the bottom of the first telescopic rod 5 is fixedly connected to the base 1 .

[0024] In this embodiment, second slide grooves 19 are provided at both ends of the installation box 7, support plates 17 are provided at the bottom of both ends of the installation plate 6, and round rods 10 are fixedly penetrated at both ends of the support plate 17. The outer wall of the bottom end of the round rod 10 is rotatably connected with a disc 11. The two discs 11 on the same side are fixed with a connecting rod 12 on the side close to each other, and the outer wall of the disc 11 is slidably connected with a round tube 13. The round tube 13 is provided with a first slide groove 14, and the bottom of the round tube 13 is fixedly connected to the base 1.

[0025] In this embodiment, the support plate 17 is slidably disposed in the second slide groove 19 , the support plate 17 is slidably connected to the installation box 7 , the connecting rod 12 is disposed in the first slide groove 14 , and the connecting rod 12 is slidably connected to the round tube 13 .

[0026] In this embodiment, a second trapezoidal plate 15 is fixed to the side of the connecting rod 12 away from the disc 11, a third telescopic rod 16 is fixed to the bottom of the support plate 17, and a first spring 18 is arranged in the third telescopic rod 16. Since the round rod 10 descends to drive the disc 11 to descend, and the disc 11 drives the connecting rod 12 to descend, and the connecting rod 12 is restricted by the first slide groove 14, the connecting rod 12 drives the second trapezoidal plate 15 to rotate and unfold, thereby achieving the technical effect of increasing the support range of the device and improving the stability of the device.

[0027] In this embodiment, the bottom of the third telescopic rod 16 is fixedly connected to the base 1 .

[0028] Working principle: When in use, place the light box 21 on the mounting plate 6, then start the motor 2, the motor 2 drives the screw rod 3 to rotate, the screw rod 3 rotates to drive the fixing block 4 to descend, the fixing block 4 descends and drives the mounting plate 6 to descend, the mounting plate 6 descends to shrink the first telescopic rod 5, and is restricted by the first telescopic rod 5, the mounting plate 6 will not deviate when it descends, the descent of the mounting plate 6 will squeeze the first trapezoidal plate 9, the first trapezoidal plate 9 will shrink the second telescopic rod 8, when the mounting plate 6 slides over the first trapezoidal plate 9, the first trapezoidal plate 9 will be rebounded by the second spring 20 and tightly clamp the light box 21, so that it is stably installed on the device, while the mounting plate 6 descends It will drive the support plate 17 to descend along the second slide groove 19. The descent of the support plate 17 drives the third telescopic rod 16 to contract and drives the round rod 10 to descend. The descent of the round rod 10 drives the disc 11 to descend. While the disc 11 descends, it drives the connecting rod 12 to slide and descend along the first slide groove 14. At the same time, the connecting rod 12 drives the second trapezoidal plate 15 to rotate and descend until it is fully unfolded, which can enhance the stability of the device. When the light box 21 needs to be replaced again, it is only necessary to remove the first trapezoidal plate 9 and reverse the motor 2 to make the mounting plate 6 rise. The support plate 17 can be rebounded by the first spring 18, and the second trapezoidal plate 15 will also be retracted to its original position to facilitate the next installation of the light box 21.
