2-in-1 thread trimmer: The integrated design of thread suction and cutting head keeps residual thread within 1mm, resulting in excellent thread cutting. Cut threads leave no residue on garments, eliminating the need for further cleaning; all threads are automatically collected in the cutting tray. Precise thread trimming: Compared to manual work, this automatic thread trimmer offers great advantages. It will not cut clothes, overlock seams, or stretch seams, creating a perfect thread trimming effect and ensuring the quality of finished garments while reducing efficiency and cost. Innovative design: Features an original square design with a 35% increased capacity compared to older models. Includes an all-round noise reduction and sound insulation design for a quieter working environment, a handle structure for convenient installation and use, and real-time temperature and speed display for clear data and accurate speed regulation. Brushless motor: Both the vacuum cleaner motor and handheld motor use brushless motors, with a lifespan approximately ten times that of traditional motors. They exhibit less vibration, preventing hand soreness or numbness even after prolonged use, and have low energy consumption. Protection mechanism: When the filter is clogged or installed incorrectly, causing negative pressure to be too high, the negative pressure check valve opens to supplement air flow, preventing damage to the motor and computer board due to overload and overheating.
