Motor thread trimming structure of sewing machine
By using a motor-driven linkage to drive a sliding module, the linear motion of the sewing machine's thread-cutting mechanism is achieved. This simplifies the transmission structure, solves the problems of unstable operation and inconvenient maintenance of existing sewing machine thread-cutting mechanisms, and achieves a highly efficient and stable thread-cutting effect.

AI Technical Summary
Technical Problem
The existing sewing machine thread-cutting mechanism has a complex structure that requires precise coordination, resulting in unstable operation and inconvenient maintenance.
Method used
The motor drives the connecting rod to drive the sliding module, which converts the rotational motion of the motor into linear motion. The moving blade and the fixed blade work together to complete the cutting, simplifying the transmission structure. The connecting rod and the sliding module replace the cam structure and multiple shafts.
Benefits of technology
It improves the operational stability and transmission speed of the wire shearing structure, facilitates disassembly and maintenance, simplifies the transmission structure, and enhances operational stability and maintenance convenience.

Abstract
This utility model discloses a thread-cutting structure for a sewing machine motor, relating to the field of sewing machines. It includes an assembly panel, with a motor connected to the bottom of the assembly panel. The motor's output shaft passes through the assembly panel and is connected to a connecting rod. A sliding module is provided on the top surface of the assembly panel. The sliding module, in conjunction with the connecting rod, converts the rotational motion of the motor into linear motion. A fixed blade is mounted at the front end of the sliding module, and a moving blade is connected to the movable end of the sliding module. This utility model uses a motor to drive the connecting rod to swing, and the swinging connecting rod drives the movable end of the sliding module to perform linear reciprocating motion, thereby causing the moving blade to perform reciprocating linear motion. Then, in conjunction with the fixed blade, it completes the thread cutting process. By using a connecting rod and sliding module instead of a cam structure and multiple shafts, the transmission structure is simplified, improving the speed of transmission response of each component and the stability of the thread-cutting structure, while also facilitating subsequent disassembly and maintenance.
