The top end of the positioning plate is inserted into the activity grooves opened on the support frame and is slidably connected to the support frame.

[0009] Preferably, a plurality of threaded holes are provided on one side of the inner wall of the movable groove provided on the support frame, and the adjusting screw is rotatably connected to the inside of the threaded holes provided on the support frame.

[0010] Preferably, a threaded rod is connected to the back of the rubber block, a second bearing is movably connected to the outer surface of the threaded rod, a gear ring is connected to the outer surface of the second bearing, and a nut is sleeved on the outer wall of one end of the threaded rod.

[0011] Preferably, a tooth groove is provided on the surface of the support pile, and the tooth ring is located inside the tooth groove provided on the support pile.

[0012] Preferably, the threaded rod and the gear ring are movably connected by a second bearing, and the nut is rotatably connected to the outer wall of one end of the threaded rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Insert the backlight module into the slide slot frame, so that the support spring supports the positioning clip and is sleeved on both sides of the bottom of the backlight module, and use rubber pads to make the two contact flexibly, and then pass one end of the fixing bolt through the through hole opened in the slide slot frame and rotate it to be connected to the inside of the threaded groove opened in the positioning clip, and limit the positioning clip, so that the bottom positioning of the backlight module is more stable, and then slide the positioning plate connected to the first bearing at the bottom end of the adjusting screw inside the support frame, adjust the spacing of the positioning plate to make it abut against both sides of the top of the backlight module, and then rotate the adjusting screw to be connected to the inside of the threaded hole opened in the support frame, and limit the positioning plate, so as to position backlight modules of different sizes, avoiding affecting the positioning of backlight modules of different sizes, resulting in low practicality.

[0015] 2. By rotating the nut to disengage it from the outer wall of the threaded rod, the gear ring moves inside the tooth groove opened in the support pile, and when the gear ring rotates, the second bearing is used to ensure that the rotation of the gear ring does not affect the angle of the threaded rod.
