Abstract

The utility model discloses a cutting device, which comprises a blade and a tool rest, wherein the blade is mounted on the tool rest, the head of the tool rest on which the blade is mounted is provided with an elastic device for slowing down the blade moving towards an object to be cut. An elastic device is also arranged between a cutter guide plate and the tool rest, and the cutter guide plate is provided with an inclined plane inclined to the gap of the blade, so that the impact force of the blade on the cutter guide plate can be reduced, namely, the cutter guide plate and the blade are rarely damaged, smaller in vibration and more precise in cutting. The blade gap of the cutter guide plate can effectively prevent the blade from swinging to and fro during cutting, so that the blade is more precise in cutting. An embossed strip of a cutter clamping plate can prevent the blade from moving upwards when the blade is not clamped tightly or impacted. The tool rest moves under the positioning of a guide post so as to result in more precise cutting. When the blade needs to be dismounted from the tool rest, a magnet can absorb the blade made of a ferromagnetic material, so that the blade cannot fall off easily to be damaged. The blade can be mounted and dismounted conveniently by a tool withdrawal groove.
