Referring to fig. 1 to 7, the present utility model provides an adjustable bracket 1, wherein the adjustable bracket 1 may include a base 50, a bracket panel 40, a plurality of telescopic members 30 arranged between the base 50 and the bracket panel 40, a pair of guide members 10 arranged front and back between the base 50 and the bracket panel 40, and a pair of moving members 20 arranged front and back between the base 50 and the bracket panel 40. The stand panel 40 is stacked on the base 50. One end of the telescopic assembly 30 is fixedly arranged on the base 50, the other end of the telescopic assembly 30 is connected to the bracket panel 40 in a back-and-forth rotatable manner, and the telescopic assembly 30 is used for extending or shortening to adjust the height of the bracket panel 40. The guide assemblies 10 are respectively provided to the bracket panel 40 so as to be rotatable back and forth, and the guide assemblies 10 have inclined guide grooves 11 extending obliquely in the left-right direction of the bracket panel 40. One end of the moving assembly 20 is slidably connected to the base 50, and the other end is slidably disposed in the inclined guide groove 11; wherein the guide assembly 10 is simultaneously raised or lowered by the same height and the stand panel 40 is raised or lowered when the moving assembly 20 slides the same distance to the left or right; when the moving assembly 20 slides to the left or right by different distances, the guide assembly 10 is raised or lowered by different heights so that the front and rear sides of the stand panel 40 are inclined to the lower side by a height difference. In other words, when the two moving assemblies 20 simultaneously slide from the right side of the higher height of the inclined guide groove 11 to the left side of the lower height of the inclined guide groove 11, the two guide assemblies 10 are simultaneously lifted up by the moving assemblies 20 to the same height, and the height of the bracket panel 40 is lifted up under the limit action of the telescopic assembly 30; conversely, when two moving assemblies 20 simultaneously slide from the left side of the lower height of the inclined guide groove 11 to the right side of the higher height of the inclined guide groove 11, two guide assemblies 10 are simultaneously lowered by the moving assemblies 20, and the height of the bracket panel 40 is lowered under the limit action of the telescopic assembly 30. In addition, when the two moving assemblies 20 slide along the inclined guide grooves 11 for different distances, the two guide assemblies 10 are respectively lifted up by the moving assemblies 20 for different heights, and the two guide assemblies 10 rotate relative to the bracket panel 40, so that the front and rear sides of the bracket panel 40 are inclined with a height difference, and the angle of the bracket panel 40 is adjusted. The magnitude of the angle is determined according to the difference between the sliding distances of the two moving assemblies 20, so that the height of the bracket panel 40 can be adjusted while adjusting the angle of the bracket panel 40. In this way, the adjustable bracket 1 can not only realize the height adjustment of the bracket panel 40, but also realize the angle adjustment of the bracket panel 40 through the simple cooperation of the moving assembly 20 and the guiding assembly 10, and the whole adjustable bracket 1 is simple, has strong portability and installability, and the whole height and angle adjusting process is easy and convenient to operate, and is suitable for being used in various scenes.
