While the two second laser ranging sensors (14) positioned at two sides slide, as each indicating rod (31) is fixedly connected with one pushing block (28), the top of the descending plate is symmetrically designed with two scale values (32), and each indicating rod (31) faces one scale value (32), the sliding distance of the two second laser ranging sensors (14) positioned at two sides can be accurately adjusted, namely the distance between the three second laser ranging sensors (14) can be accurately adjusted;
when the length and width of the acrylic plate change, the electric push rod (33) is started through the controller, so that the output end of the electric push rod drives the mounting plate (34) to extend towards one end close to the guide plate (20), and the first laser ranging sensor (12) on the mounting plate (34) is driven to extend towards one end close to the guide plate (20), so that the first laser ranging sensor (12) can always emit laser to the top of the workbench (11) to realize ranging even when the size of the acrylic plate to be measured changes.
