The driving motor drives the driving gear, the driven gear and the threaded adjustment rod to rotate synchronously through the coupling. The threaded adjustment rod rotates synchronously and acts on the threaded hole inside the sliding plug-in block to drive the material placement frame to move to the top through the convex blocks on both sides along the limiting slide groove inside the limiting frame.

An electric telescopic rod 901 is installed on the upper side of the mounting base plate 5, and one end of the electric telescopic rod 901 is connected to the baffle 9.

[0032] In the specific implementation, in order to facilitate the loading of the liquid crystal display panel, the material frame 3 equipped with the liquid crystal display panel is placed on the upper side of the transmission belt 502, and the guide layers 301 on both sides of the material frame 3 are plugged with the sliding plug-in layer 302 on the upper side of the installation base plate 5, and the transmission roller 501 is started to drive the transmission belt 502 to transport the material frame 3 until the material frame 3 is transported to the position abutting against the baffle 9. At this time, the upper side of the material frame 3 is plugged with the guide block 603 through the sliding plug-in block 602, and the driving motor 601 is started. The driving motor 601 drives the driving gear 601a to rotate through the coupling and mesh with the driven gear 601b on the outside, thereby driving the four driven gears 601b and the threaded adjustment rod 601c installed in the middle thereof to rotate synchronously, and the threaded adjustment rod 601c is rotated synchronously. 01c rotates synchronously with the threaded hole inside the sliding plug-in block 602, and drives the material loading frame 3 to move to the top through the protrusions on both sides along the limiting slide groove 604d inside the limiting frame 604.

[0034] In specific implementation, since the spring has the characteristic of being easy to deform, long-term use of the spring for resetting operation will cause the block 403 to be reset and offset, and the resetting effect will gradually decrease. When the electric feeding push rod 2 pushes the LCD display panel, the LCD display panel will abut against the abutment plate 701e installed at one end of the damping rod 701. As the electric feeding push rod 2 continues to push forward, the abutment plate 701e will move to the side where the damping rod 701 is located, and during the movement, the block 403 will be pulled upward by the traction rope 401 to open the notch at the bottom of the water storage chamber 404, so that the water source inside the water storage chamber 404 will flow out.
