Claims

[Scope of utility model registration request]

It is attached to a sewing machine that has a needle that moves up and down with a thread inserted through its tip above the feed mechanism that feeds the sheet material to be sewn, and cuts off the excess portion of the sheet material at the same time as sewing the sheet material to be sewn. The cutting device has a main cutting part on one half of the lower edge, which is the cutting edge, with one side edge as the cutting edge, and the other half has a main cutting part that protrudes below the main cutting part, and has a distal end thereof. An upper blade that can be raised and lowered on the side of the needle, and a guide part whose edge is shifted inward in the thickness direction from the cutting edge of the main cutting part, and an upper blade that can be freely raised and lowered on the side of the needle, and directly below the upper blade, It consists of a lower blade provided on a fixed part that does not move depending on the feeding mechanism, and as the upper blade lowers, the side surface of the guide part of the upper blade can freely slide into contact with the cutting edge of the lower blade. A cutting device attached to a sewing machine.
