Preferably, the number of the locking holes is at least four, and the four locking holes are respectively provided with four corners of the base.

Preferably, the glass sheet is a common glass sheet or an ultrathin glass sheet.

Preferably, the thickness of the ultra-thin glass is 0-0.1 mm.

Preferably, the four peripheries of the bearing plate and the four peripheries of the bearing groove are hermetically connected through glue.

Preferably, the glass cutting jig can be applied to cutting of thin film products.

The invention has the following beneficial effects: the invention provides a glass cutting jig, compared with the prior art, the glass cutting jig is additionally provided with a bearing plate and a bearing groove, the bearing plate is a porous ceramic plate, on one hand, a common glass sheet or an ultrathin glass sheet is adsorbed on the bearing plate through a negative pressure component, the porous ceramic plate is provided with a plurality of pores, the uniformity of stress can be ensured, the structure is simple, on the other hand, because the bearing groove and the bearing plate are arranged in a matched mode, and the four peripheries of the bearing plate and the four peripheries of the bearing groove are connected in a sealing mode, the tolerance can be reduced, and the airtightness and air tightness can be ensured. Meanwhile, the glass cutting jig can also be applied to thinning other film products.
