The invention provides a glass round hole forming device, and relates to the field of glass cutting. The glass round hole forming device comprises a fixing mechanism, a cutting mechanism is fixedly installed at the bottom end of the outer surface of the fixing mechanism, a traction mechanism is fixedly installed in the middle of the fixing mechanism, and the traction mechanism is fixedly connected with the cutting mechanism. According to the glass round hole forming device, the device is fixed to the center of glass, a fixing base can rotate through rotation of a rotating sleeve, meanwhile, a pulling rope is wound around the outer surface of a reel and can pull the fixing base to move towards the outer side, the fixing base can rotate along a spiral line, when the fixing base moves to make contact with a baffle, the reel is continuously rotated to start rotating, so that a circle with a specified diameter can be drawn by using a cutting knife, the cutting knife can quickly get close to the inner side under the action of a reset spring by loosening the rotating sleeve, so that glass inside the circle can be nicked, and the problem that a nick is easy to exceed the diameter of the circle in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of glass cutting, in particular to a device for opening round holes in glass. Background technique [0002] Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals as the main raw material and a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides. Widely used in buildings, used for wind and light transmission, belongs to the mixture. [0003] In the process of opening a round hole in the existing glass, it is necessary to use a glass knife to create a scratch in the middle of the round hole, but the scratch is easy to draw on the outside of the round hole during the drawing process, which will cause the outside of the round hole to be damaged when the glass is struck. broken glass. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a glass ro...
