Problems solved by technology

[0008] However, the cutting tool in Japanese Patent Application Laid-Open No. 9-123088 requires a mechanism for locking the rotation of the bracket. Therefore, in addition to the complicated structure, it is necessary to carry out the operation for turning the bracket before performing the dial operation for rotating the bracket. Unlocking lever operation, so cumbersome to operate
In addition, there is a risk of hand contact with the blade when operating the lever
[0009] In the cutting tool disclosed in Japanese Patent Laying-Open No. 2002-239266, since the tip of the knife is always exposed from the support, there is a risk of contact between the hand and the tip of the knife during replacement.

Abstract

Provided is a cutting tool applicable to cutting machines of various structures wherein the cutter blade can be replaced smoothly in safety with simple structure. A cutting tool (1) has a slider (20), a holder member (30) which holds the cutter blade (7), and a member (40) for attaching / detaching the holder member to or from the slider in a state where the cutter blade is covered with a cover member (43), wherein the cover member is provided with a protrusion (47), a groove (35) is provided in the holder member, and the protrusion is moved in a sliding path by the operation of fixing the member (40) to the slider along with the holder member, and the cutting edge is exposed through a notch (48).

Description

technical field [0001] The present invention relates to a cutting tool used to be attached to a cutting machine that slides a blade to cut a sheet, and particularly relates to a cutting tool that improves safety and workability when replacing a blade. Background technique [0002] In many cutting tools mounted on a cutting machine that slides a blade to cut a sheet, a holder for holding a disc-shaped blade is attached to a slider that moves in a cutting direction. [0003] For such a cutting tool, the following scheme has been proposed in the past: a support is provided in a rotatable manner on the slide block, and a notch that can expose a part of the tip of the blade is provided on the support, so that when the blade is replaced, the The holder rotates so as to cover the tip of the knife (Japanese Patent Application Laid-Open No. 9-123088). [0004] When replacing the blade, after the bracket is removed from the slider, the blade is removed from the bracket and replaced w...
