Most existing fixing fixtures center and clamp the glass on the four sides to achieve fixation. However, when the glass is cut in the middle, a certain gap will be generated. At this time, the glass is easy to leave the positioning plate, causing the position of the glass to change, affecting its subsequent cutting accuracy. In addition, when the existing fixing fixture positions and clamps the four sides of the glass, it is generally driven by a set of lead screw assemblies to drive the clamping plates on both sides to approach for clamping, and then another set of lead screw assemblies to drive the clamping plates on the other two sides to approach for clamping. This method requires two motors to drive the two sets of lead screw assemblies respectively, resulting in high material and maintenance costs, and requires a control system for linkage control.
