[0012] Furthermore, the clamping rod and the connecting rod have the same shape, and the clamping rod is slidably connected to the adjustment sleeve.

[0013] Furthermore, the sliding sleeve is C-shaped, and the sliding sleeve is slidably connected to the guide plate.

[0014] The utility model provides a screen positioning fixture, which has the following beneficial effects:

[0015] 1. The utility model sets an adjustment component. When positioning screens of different widths, the first bolt can be loosened to move the slide on the guide plate, and the position of the slide can be adjusted according to the left and right width of the screen. When the second bolt is loosened, the position of the adjustment sleeve can be moved according to the front and back width of the screen, so that the limit plate can fit the four corners of screens of different sizes to quickly limit them, which is conducive to expanding the use range of the screen positioning fixture. At the same time, the anti-slip groove can increase the friction force when the hand is adjusted;

[0016] 2. The utility model provides a locking assembly. After the screen is placed in the limit plate for preliminary positioning, the screw can be driven to rotate by the handle. At this time, the sliding sleeve will limit the rotation of the clamping rod under the limit of the guide plate. Therefore, when adjusting, the two limit plates close to one side of the clamping rod can be used to press and position the screen, thereby avoiding slippage during clamping. When disassembling, only the handle needs to be rotated in the opposite direction to loosen the limit plate from the screen, which is very convenient during disassembly.
