[0038] Then, the operator can slide the positioning member 5, at this time, the ball 9 on the limiting block 7 rolls and supports the limiting block 7 and the positioning member 5, the operator can conveniently slide the positioning member 5, after the positioning member 5 is slid to the position, the operator can re-screw the handle piece 13 on the adjusting stud 12, so that the limiting ring 8 and the limiting block 7 realize the clamping of the transverse guide rail 2 or the longitudinal guide rail 3 again.

[0039] Finally, the operator can guide the glass substrate by the guide wheel 4, the glass substrate is stably limited and guided by the guide wheel 4 on the multiple transverse guide rails 2 or longitudinal guide rails 3 arranged at intervals, and the processing precision of the glass substrate glue coating processing is improved.
