When the height difference needs to be adjusted, the fastening screws on both sides of the glass pillar need to be loosened.

[0009] Furthermore, the swing arm is hinged to the bottom of the lifting frame through a connecting rod. When the swing arm is rotated until the connecting rod is perpendicular to the ground, the lifting bracket mechanism is at the highest point.

A lifting bracket mechanism 2 is provided in the bottom frame 5 of the frame mechanism 1, a transmission mechanism 3 is provided above the lifting bracket mechanism 2, and a positioning mechanism 4 is provided above the transmission mechanism 3. The positioning mechanism 4 is fixed on the bottom frame 5 through the positioning mechanism frame 20; the transmission mechanism 3 transmits the glass or plate to the lifting bracket mechanism 2, and the lifting bracket mechanism 2 raises the glass or plate to the center of the positioning mechanism 4 and then descends to drop it on the belt transmission group 13 of the transmission mechanism 3.

[0030] like Figure 3 As shown, the lifting bracket mechanism 2 includes a lifting frame 7, a cylinder group 9 and a glass bracket 10; rocker bars 8 are installed at both ends of the bottom of the lifting frame 7, and the rocker bars 8 are driven to rotate by the cylinder group 9; six glass brackets 10 parallel to the transmission mechanism 3 are fixed on the top of the lifting frame 7, and the glass brackets 10 do not interfere with the transmission mechanism 3 when the lifting bracket mechanism 2 rises or falls; four glass pillars 11 for supporting curved glass are evenly fixed on the sides of the two glass brackets 10 located inside the transmission mechanism 3 in a horizontal position.

[0031] The positions of the glass pillars 11 on the two glass brackets 10 correspond one to one; the top surface of the glass pillar 11 is slightly higher than the top surface of the glass bracket 10, and the height difference between the glass pillar 11 and the glass bracket 10 is determined when the glass pillar 11 is fixed.
