Description

Technical Field

[0001] The utility model relates to the technical field of glass cutters, in particular to a glass cutting cutter head. Background Art

[0002] Glass cutting is usually done by a glass cutting machine. Due to the different thicknesses and types of glass to be cut, different cutter heads need to be replaced for cutting different glass. After replacing the cutter head, the cutter alignment needs to be performed again, which is time-consuming. Although there are cutter heads that can replace the cutter wheel in the prior art, they all replace the cutter wheel in a rotating manner. This type of cutter head must improve the cutter seat and use a dedicated cutter head. However, some types of cutter wheels cannot be matched and installed with this type of cutter head.

[0003] The existing Chinese patent application number CN202321392411.0 discloses a glass cutting tool head with multiple tools, which includes a base, a first groove is provided on the upper side of the base, and at least one second groove is provided on the lower side of the base. Two connecting holes are provided between each second groove and the first groove. A knife rod is slidably connected in each connecting hole, and the lower end of the knife rod is fixedly connected to the knife seat. A knife wheel is installed in the knife seat. A rack is fixedly connected to one side of each knife rod, and a gear is rotatably connected in the second groove. Both racks are meshed with the gear. Although the device does not need to rotate the knife seat, and the knife seat does not need to be customized, the knife seat and knife wheel on the market can be directly installed and used after purchase. However, once the knife rod is broken, the entire base needs to be disassembled, which is very troublesome to replace. Utility Model Content
