Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to specific embodiments. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, 2 and 3, the prism laser cutting jig comprises a substrate 1, wherein a second clamping plate 3 is transversely arranged in the middle of the substrate 1 and fixedly mounted on the substrate 1 through bolts, and the substrate 1 is divided into a front area and a rear area by the second clamping plate 3.

The arrangement of the front area and the rear area of the substrate 1 is the same, 11 clamping edges 5 are uniformly arranged, the clamping edges 5 are perpendicular to the second clamping plate 3 and are uniformly arranged, 10 clamping grooves 6 (the shapes of which are matched with those of prism products 12) are formed between the adjacent clamping edges 5, and 20 prism products 12 can be placed on the whole substrate 1. And 9 cutting grooves 7 are formed in the clamping edge 5 in a length needing to be cut.
