Please refer to Figures 1-5. The purpose of this embodiment is to provide a slider 23; the slider 23 can move up and down in the vertical tube 3; the slider 23 is fixedly connected to the outer tube 2, the inner tube 1 is arranged inside the outer tube 2, the inner tube 1 can move horizontally along the outer tube 2, and the end of the inner tube 1 away from the slider 23 is provided with a front end plate 15. The lower end of the inner tube 1 away from the outer tube 2 is connected to the mounting frame 4, and the projector is mounted on the mounting frame 4. The inner tube 1 of the adjustable telescopic bracket can slide and adjust in the outer tube 2, and the outer tube 2 can slide and adjust in the vertical tube 3, so that the mounting frame 4 can be adjusted in both horizontal and vertical directions, which is convenient for adjusting the position of the mounting frame 4 and convenient for the use of the projector.

The inner tube 1 is provided with a first slide groove 11, and a first limit block 12 that can slide along the first slide groove 11 is provided in the first slide groove 11, and a threaded hole is provided in the first limit block 12. A first through hole is provided at the top of the end of the outer tube 2 away from the slider 23, and a first screwing member 13 is provided in the first through hole, and the first screwing member 13 is threadedly connected in the threaded hole of the first limit block 12. When adjusting the position of the inner tube 1, since the first limit block 12 is limited in the first slide groove 11, the first limit block 12 does not rotate, and the first screwing member 13 is rotated so that the first limit block 12 no longer presses against the inner tube 1, so that the first limit block 12 can slide horizontally along the first slide groove 11, that is, the inner tube 1 and the outer tube 2 slide relative to each other. After adjusting the relative position of the inner tube 1 and the outer tube 2 in the horizontal direction, the first screwing member 13 is rotated in the opposite direction again so that the first limit block 12 presses against the inner tube 1, and the position adjustment in the horizontal direction is completed.

Furthermore, a first limiting sleeve 14 is sleeved on the outer side of the end of the inner tube 1 close to the slider 23, and a second limiting sleeve 21 is sleeved on the inner side of the end of the outer tube 2 away from the slider 23. The first limiting sleeve 14 and the second limiting sleeve 21 can reduce the wear between the inner tube 1 and the outer tube 2, and the end of the second limiting sleeve 21 can limit the end of the first limiting sleeve 14 to prevent the inner tube 1 and the outer tube 2 from being separated from each other during the adjustment process.

In a preferred embodiment, the inner tube 1 and the outer tube 2 are hollow structures for the lead wires to pass through, and the rear end plate 22 and the slider 23 are also provided with through holes for the lead wires to pass through.

In this embodiment, the vertical tube 3 is provided with a second slide groove 32 and a third slide groove 33, the slider 23 is slidably arranged in the third slide groove 33, the second slide groove 32 is provided with a second limit block 24 and a third limit block 26, and the second limit block 24 and the third limit block 26 are respectively provided with a threaded hole. The slider 23 is provided with a first extension plate 231 and a second extension plate 232 at both ends, and the first extension plate 231 and the second extension plate 232 are respectively provided with a second through hole 233 and a third through hole 234. The second through hole 233 is provided with a second screwing member 25, and the second screwing member 25 is threadedly connected to the threaded hole of the second limit block 24; the third screwing member 27 is provided in the third through hole 234, and the third screwing member 27 is threadedly connected to the threaded hole of the third limit block 26.

When adjusting the position of the outer tube 2, since the second limit block 24 and the third limit block 26 are limited in the second slide groove 32, the second limit block 24 and the third limit block 26 do not rotate, and the second screw member 25 and the third screw member 27 are rotated so that the second limit block 24 and the third limit block 26 are no longer pressed against the vertical tube 3, so that the second limit block 24 and the third limit block 26 can slide vertically along the second slide groove 32, that is, the outer tube 2 and the vertical tube 3 slide relative to each other, and the relative position of the slider 23 and the third slide groove 33 is adjusted at the same time. After adjusting the relative position of the outer tube 2 and the vertical tube 3 in the vertical direction, the second screw member 25 and the third screw member 27 are rotated in the opposite direction again to make the second limit block 24 and the third limit block 26 press against the vertical tube 3, and the position adjustment in the vertical direction is completed.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included in the protection scope of this utility model.
