Embodiment Construction

[0005] As shown in the figure, a cutting torch 1, a shaft handle 2, a cutting torch handle 3, a base 4 and a steel plate 5. Both the torch handle 3 and the shaft handle 2 adopt a retractable structure. The torch handle 3 forms an angle of 90° with the axel 2. Shaft 2 is connected with base 4 and can rotate on the base. Base 4 keeps cutting torch 1 stable by its own weight. Before cutting the steel plate 5, adjust the length of the torch handle 3 and the height of the shaft handle 2, then ignite and cut the steel plate 5, and push the torch handle 3 to rotate around the shaft handle 2 to cut out the required arc-shaped steel plate.

Abstract

A circle cutting device has a cutting torch with a handle, and an axle connected perpendicular to said handle of cutting torch and able to rotate on a base. It can be used to cut on steel plate to obtain a circular steel plate.

Description

technical field [0001] A cutter. Background technique [0002] Ordinary hand-held cutters generally hold the handle of the cutting torch by hand, and cut bit by bit along the handwriting drawn in advance on the steel plate through the human naked eye. However, when cutting arc-shaped steel plates, due to human inevitable judgment errors, it is not easy to cut the part to be cut along the arc line even if it is cut bit by bit along the handwriting. Contents of the invention [0003] In order to solve the problem of irregular cutting circles of hand-held cutting torches, the present invention proposes a circular cutter, including a cutting torch, which is characterized in that: one end of the handle of the cutting torch is vertically connected to a shaft, and the shaft is mounted on the base and can be rotated on the base. In order to facilitate cutting circles and arcs with different radii, a further improvement of the present invention is that the handle of the cutting t...
