Abstract
The invention relates to a trimming device of a sewing machine, comprising a base, a stationary blade, a movable blade, a transmission mechanism, a driving mechanism and a control mechanism. The subassemblies of the stationary blade and the subassemblies of the movable blade are positioned under the needle of the sewing machine, and the movable blade and the stationary blade can perform relative shearing movement for trimming yarns. The transmission mechanism and the driving mechanism are both arranged at the lower part of the surface of the sewing machine, and positioned under the needle of the sewing machine. In the invention, the complex mechanism of the original trimming driving device is simplified, and the original sewing machine without being provided with a trimming device can be installed directly. The situation that the trimming devices only in a few brands can be installed after being modified and processed can be changed; since modification processing needs to detach components, perform special mechanism processing and then assemble the components again, the cost can be saved. Therefore, in the invention, not only the application area of the trimming device is enlarged, and the trimming device can be directly installed without being dismounted or processed on most brands of the trimming devices, but also the cost caused by dismounting and processing operations can be saved.
