New description: According to the original page [New technical field] This creation department is about a sewing machine sewing machine cutting device, especially one suitable for three-line overlock or three-line overlock and double-line lock The cutting operation of the suture is simple, the assembly is convenient, and the structural innovation of the suture cutting device of the overlock sewing machine can be surely cut. [Prior Art] _] Please refer to the figure-figure to reveal the sewing thread traces of the three-wire overlock seam, and the second figure reveals the stitching stitch of the three-thread overlock seam of the first figure. A perspective view of the cutting device in one direction, and a third view is a perspective view of the second embodiment of the overlock sewing machine cutting device. [0003] The overlock sewing machine cutting device (1) is mainly provided with a cloth guide (12) on one side of a chain cutter (1 1 ), and the cloth guide (12) has a perforation thereon. (12 1), corresponding to a cutting edge of a cutter set (13) disposed on the cloth guide (12), and a suction tube (14) mounted on the other side of the cloth guide (12) Its suction port (1 4 1 ) corresponds to the perforation (1 2 1 ). A transmission rod (15) is formed with a notch portion (1 5 1 ) at one end thereof, and the cutting power unit (not shown) of the overlock machine is connected by the notch portion (1 5 1) to make the transmission rod (1 5) And the sewing power group of the overlock machine is synchronized to further drive the cutter group (13) to operate. The suction pipe (14) is connected to a suction source (not shown), and the suction port (141) is operated by the suction source to generate suction into the suction pipe (14). [0004] When the sewing fabric is finished and the seam of the three-line overlock is to be cut, the presser foot [not shown] is lifted up, and the sewing fabric is pushed toward the suction port (1002 leg f single number A〇101 3 pages / total 25 pages 1〇13〇14796-〇M430490

However, this suture cutting device can only be applied to the overlocked airport joint of the three-line overlock. For the overlock sewing machine with the three-line overlock and double-line stitching as shown in the fourth figure, the seam sewing machine cannot be executed. Line cutting operation. Moreover, the three-thread over-stitched overlock sewing machine only generates suction through the suction port of the cutter group to attract the empty thread suture to the suction tube through the suction source, and there is no other auxiliary mechanism, therefore, the suction force of the suction source must be It is quite large, in order to smoothly attract the suture into the suction tube, and the huge suction will inevitably lead to great noise. The fourth picture of the ginseng is not intended to reveal the sewing stitch of the three-line overlock and the double-line lock seam. The fifth picture reveals that the stitching stitch is the fourth figure.

Therefore, under the continuous cutting operation of the cutter group, noise will be generated, and the cutter group will even drive the relevant components of the cutter group. It is prone to wear and tear 'increased damage rate of parts. [New content] The main purpose of this creation is to provide a cutting operation that can be used for three-line overlock or three-line overlock and double-line seam sewing, and has a simple structure, convenient assembly, long service life, and can be confirmed.
