The cross-sectional lengths are all the same, and the first slide groove and the second slide groove are staggered in a design. Even if the staff drives the T-shaped frame to slide quickly inside the first slide groove, the first slide groove can limit the movement range of the T-shaped frame, thereby preventing the support frame from driving the LCD display device to easily escape from the mobile phone motherboard module, thereby improving the stability of the use of the LCD display device, and when the staff needs to disassemble the LCD display device, the staff can simply pull the T-shaped frame out of the first slide groove and enter the second slide groove.

[0011] Preferably, the vertical cross-section of the pressing plate is an I-shape, and the cross-sectional length of the contact portion between the pressing plate and the T-shaped frame is smaller than the cross-sectional length at both ends of the pressing plate, which can prevent the pressing plate from completely escaping from the T-shaped frame, thereby limiting the movement space of the pressing plate.

[0012] Preferably, resistance-increasing pads are bonded to opposite ends of the first slide groove and the pressure plate, and the two resistance-increasing pads are in contact with each other, which can increase the friction between the first slide groove and the pressure plate and further improve the operating stability of the liquid crystal display device.

[0013] Preferably, a pull ring is fixedly connected to one end of the adjustment frame, and the corners of the pull ring are rounded, which can make it easier for the staff to move the T-shaped frame and the adjustment frame, reducing the difficulty of adjustment for the staff.

[0014] The beneficial effects of the utility model are:

[0015] 1. The first slide groove and the second slide groove are staggered. Even if the staff drives the T-shaped frame to slide quickly inside the first slide groove, the first slide groove can limit the movement range of the T-shaped frame, preventing the support frame from driving the LCD device to easily escape from the mobile phone motherboard module, thereby improving the stability of the use of the LCD device. When the staff needs to disassemble the LCD device, the staff only needs to pull the T-shaped frame out of the first slide groove and enter the second slide groove. At this time, the T-shaped frame loses its obstruction and the staff can quickly disassemble the LCD device.

[0016] 2. The spring sheet can press the pressure plate against the inside of the first slide groove, which can lock the LCD device in the adjusted position. Even if the staff tilts or stands up the LCD device, the LCD device can still operate stably in this position, thereby improving the overall practicality of the positioning mechanism. The staff can separate the pressure plate from the first slide groove by pressing, so that the staff can slide the LCD device more easily. BRIEF DESCRIPTION OF THE DRAWINGS

The specific model can be selected according to actual needs. At the same time, the mobile phone motherboard module 1 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be repeated here.

[0026] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a first slide groove 12 is provided on the top of the mobile phone motherboard module 1, and a second slide groove 13 connected to the first slide groove 12 is provided at one end of the mobile phone motherboard module 1, the first slide groove 12 and the second slide groove 13 are staggered, and a slide cavity 21 is provided at the bottom of the support frame 2, and the positioning mechanism 5 includes a T-shaped frame 51 slidably connected to the inside of the slide cavity 21, the bottom of the T-shaped frame 51 passes through the slide cavity 21 and extends to the inside of the first slide groove 12, and the other end of the T-shaped frame 51 passes through the outside of the slide cavity 21, the overlapping length of the first slide groove 12 and the second slide groove 13 is greater than the width of the T-shaped frame 51, and the cross-sectional length of the bottom opening of the slide cavity 21 is the same as the cross-sectional length of the first slide groove 12 and the second slide groove 13 added together; a rubber spring 52 is fixedly connected to the surface of the T-shaped frame 51, and one end of the rubber spring 52 is fixedly connected to the slide cavity 21; a deformation groove 511 is provided on the surface of the T-shaped frame 51, and the other end of the rubber spring 52 is fixedly connected to the deformation groove 511.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the inside of the T-shaped frame 51 is slidably connected with an adjusting frame 53, one end of the adjusting frame 53 penetrates to the outside of the T-shaped frame 51, and the inner side of the adjusting frame 53 is provided with a spring sheet 54 fixedly connected to the T-shaped frame 51, and the spring sheet 54 is in a compressed state at this time, and the bottom of the spring sheet 54 is fixedly connected with a pressing plate 55 slidably connected to the T-shaped frame 51, and the bottom of the pressing plate 55 penetrates the T-shaped frame 51 and contacts the first slide groove 12; the vertical cross-sectional shape of the pressing plate 55 is an I-shaped, and the cross-sectional length of the contact part between the pressing plate 55 and the T-shaped frame 51 is smaller than the cross-sectional lengths at both ends of the pressing plate 55; the first slide groove 12 and the pressing plate 55 are bonded with resistance-increasing pads 56 at the opposite ends, and the two resistance-increasing pads 56 are in contact; one end of the adjusting frame 53 is fixedly connected with a pull ring 57, and the corners of the pull ring 57 are rounded;

[0028] When the staff slides the liquid crystal display device 3, the staff only needs to press the pull ring 57, the pull ring 57 drives the adjustment frame 53 to move, the adjustment frame 53 bends the spring sheet 54, the spring sheet 54 drives the pressure plate 55 to rise, and the pressure plate 55 drives the resistance increasing pad 56 connected thereto to separate from another resistance increasing pad 56, and then the staff can easily slide the support frame 2, and the support frame 2 drives the liquid crystal display device 3 to slide; when the liquid crystal display device 3 is moved into place, the staff only needs to release the pull ring 57, at this time the spring sheet 54 quickly resets the adjustment frame 53, the pull ring 57 and the pressure plate 55, the pressure plate 55 drives the resistance increasing pad 56 connected thereto to press tightly against another resistance increasing pad 56, at this time the liquid crystal display device 3 can be locked in this position more stably, even if the liquid crystal display device 3 is placed vertically, the liquid crystal display device 3 is difficult to slide, thereby improving the practicality of the positioning mechanism 5.

[0029] When the utility model is in use:

[0030] During the sliding of the support frame 2, the support frame 2 drives the T-shaped frame 51 to slide inside the first slide groove 12 through the slide cavity 21. During this process, the T-shaped frame 51 cannot be separated from the first slide groove 12, and when the T-shaped frame 51 contacts the two vertical inner walls of the first slide groove 12, the first slide groove 12 prevents the support frame 2 from driving the liquid crystal display device 3 to normally separate from the mobile phone motherboard module 1 through the T-shaped frame 51. If the staff wants to remove the liquid crystal display device 3, the staff needs to slide the support frame 2 up to the extreme position. At this time, the T-shaped frame 51 and the first slide groove 12 are in contact with each other. The first slide groove 12 is abutted together, and the T-shaped frame 51 is aligned with the second slide groove 13. The staff only needs to actively pull the pull ring 57 outward, and the pull ring 57 drives the T-shaped frame 51 to move as a whole through the adjustment frame 53. The T-shaped frame 51 moves from the first slide groove 12 into the second slide groove 13. When the T-shaped frame 51 is abutted against the second slide groove 13, the staff can continue to slide the support frame 2 up, and the support frame 2 drives the T-shaped frame 51 to slide out of the second slide groove 13 through the slide cavity 21. At this time, the staff can remove the support frame 2 together with the liquid crystal display device 3.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
