Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] When cutting the glass, because the texture of the glass is brittle, the glass is easy to break when cutting. Especially when cutting special-shaped holes on the glass, the common holes on the glass are round holes. If the knife is not round when opening the round holes, the glass will easily break. To solve the above problems, the figure 1 A glass knife shown includes a positioning device and a cutting device. The cutting device rotates around the positioning device. When a round hole is opened, the positioning device is fixed on the glass surface, and then the position of the knife rest 7...

Abstract

The invention relates to a glass cutter. The glass cutter comprises a positioning device and a cutting device. The cutting device is rotated around the positioning device. The positioning device comprises a cone funnel. A sucking disc is installed under the cone funnel. The sucking disc is connected with a spanner above the cone funnel. The cutting device comprises a positioning rod and a cutter frame. One end of the positioning rod is provided with a sleeve. The sleeve is sheathed on the cone funnel. The cutter frame is provided with a cutter head. The cutter frame is cylinder-shaped. The upper end of the cutter frame is opened and provided with a groove along the axis. The width of the groove is 1-1.5 mm wider than that of the positioning rod. Two sides of the groove are provided with a clamping body. The outer side of the clamping body is provided with an external thread. The clamping body is matched with a fastening knob. The cutter frame is provided with a groove. The positioning rod passes through the groove, and is capable of fixing the cutter frame and the positioning rod by the fastening knob tightly. The aspheric tapping or failure caused by the sliding between the cutter frame and cutter rod in the feeding process can be prevented.

Description

technical field [0001] The invention relates to the field of glass cutters, in particular to a glass cutter which can be used for cutting circular holes. Background technique [0002] Glass is formed by melting silicon dioxide and other chemicals together (mainly produced from: soda ash, limestone, quartz). A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling to cause it to crystallize. The main component of ordinary glass is silicate double salt, which is an amorphous solid with irregular structure. Widely used in buildings, used for wind and light transmission, belongs to the mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Glass is an important building material. Glass is widely used in doors, windows, curtain walls and other occasions. [0003] But the...
