[0031] See also Figure 1 and2 The support assembly 100 includes a detection stand 110, a placement rack 120, a vertical plate 130 and a locking piece 150. One end of the placement rack 120 is rotatably disposed on the top of the detection stand 110. The vertical plate 130 is disposed on the top of the detection stand 110. The locking piece 150 is disposed on the side of the placement rack 120, and the locking piece 150 abuts against the vertical plate 130.

[0032] Among them, a fixed block 111 is set on the top of the detection platform 110, and the bottom end of the placement rack 120 is rotatably connected to the fixed block 111 through a rotating shaft. By setting the fixed block 111, the rotating shaft is fixed to the end of the placement rack 120, and the rotating shaft passes through the fixed block 111, which is used to cooperate with the rotating shaft to realize the rotation installation of the placement rack 120.

[0033] In this embodiment, the locking member 150 includes a threaded column 151 and a pressing head 152. The threaded column 151 is fixedly connected to the pressing head 152. The threaded column 151 is threadedly connected to the side of the placement rack 120. By setting the threaded column 151 and the pressing head 152, rotating the pressing head 152 drives the threaded column 151 to rotate, and the threaded column 151 drives the pressing head 152 to press tightly against the vertical plate 130 for positioning.

[0034] Specifically, the vertical plate 130 is provided with an arc hole 131, the threaded column 151 slides through the arc hole 131, and the pressure head 152 abuts against the vertical plate 130. By providing the arc hole 131, the arc hole 131 and the placement frame 120 rotate concentrically, so that the threaded column 151 can be moved and adjusted in the arc hole 131.

[0035] In a specific implementation manner, a support leg 140 is disposed at the bottom of the detection stand 110 , and an anti-slip pad is disposed at the bottom of the support leg 140 .

[0036] See also Figure 1 , 2 , 3 and 4, the adjustment component 200 includes a baffle 210, an adjustment screw 220 and an adjustment plate 240, the baffle 210 is arranged at the bottom of the placement rack 120, the adjustment screw 220 threadedly penetrates the placement rack 120, the adjustment plate 240 is slidably arranged in the baffle 210, and the adjustment plate 240 is movably connected to the end of the adjustment screw 220.

[0037] It should be noted that a guide bar 121 is provided in the placement frame 120, and the end of the adjustment plate 240 is slidably mounted on the surface of the guide bar 121. By setting the guide bar 121, the curved surface of the guide bar 121 can guide the adjustment plate 240 to move stably in a straight line, and usually bear the pressure of the LCD screen on the adjustment plate 240.

[0038] In a specific embodiment, a knob 222 is provided at one end of the adjusting screw 220 away from the adjusting plate 240, and the knob 222 has a groove.

[0039] Among them, the baffle 210 and the detection stand 110 are L-shaped, and rubber pads are provided on the surfaces of the detection stand 110 and the baffle 210. The baffle 210 and the detection stand 110 combined into an L-shape are used to support and place a liquid crystal display screen, and the rubber pads reduce the wear on the display screen.

[0040] The working principle of the LCD screen electrical testing frame is as follows: when in use, the knob 222 is turned according to the size of the LCD screen to be tested to drive the adjusting screw 220 to rotate, the adjusting screw 220 rotates and moves axially, and the adjusting screw 220 pushes the adjusting plate 240 to move. The adjusting plate 240 moves stably under the support and guidance of the guide bar 121, ensuring that the LCD screen can support its top when placed, so as to adapt to screens of different sizes. Then, the bottom of the LCD screen is first placed on the baffle 210, and the connecting wire on the detection stand 110 is plugged into the back interface of the LCD screen. Then, the LCD screen is lowered onto the placement frame 120, and the LCD screen is supported by the adjusted adjusting plate 240. The idle part of the placement frame 120 can accommodate the protrusion on the back of the display screen and the connecting wire, ensuring that the display screen is placed stably, and the connecting wire is also easy to organize. At the same time, the angle can be adjusted by first loosening the threaded column 151 and the pressure head 152, rotating the placement frame 120 to adjust the angle, and then tightening it, so that the detection personnel can watch it conveniently.
