[0020] Working principle: When the present utility model is in use, first, the L-shaped structure composed of the base plate 1 and the cross plate 2 provides basic support for the entire device. The upright column 3 plays a role in connecting different components. Through the cooperation of the mounting seat 4 on the upright column 3 and the clamping bent plate 5, the entire device is fixed on the overlock sewing machine. Then, the locking bolt 6 can be used to further lock the clamping bent plate 5, thus ensuring the stability of the device. Immediately afterwards, after the micro motor 7 on the fixed seat 8 is started, the output shaft of the micro motor 7 drives the transmission shaft 9 to rotate, causing the rotating roller 10 on the transmission shaft 9 to rotate accordingly, thereby realizing the cloth supporting operation. During the cloth supporting process, the compression spring 11 on the upright column 3 can apply pressure to the moving seat 12. The moving seat 12 slides on the upright column 3 and drives the rotating roller 10 to move through the connecting shaft 13, so that the two rotating rollers 10 can clamp the cloth. The other end of the connecting shaft 13 is inserted into the vertical plate protruding from one end of the cross plate 2. By extending the front end of the connecting shaft 13 into the guiding port, the stability of the connecting shaft 13 during descent can be improved to adapt to cloths of different thicknesses. In addition, rotatable rollers are installed on the connecting frames 14 on both sides of the connecting shaft 13. Whenever the rotating roller 10 rotates, if the friction force is too large, it may drive the cloth to rotate. At this time, the rollers can play a role in preventing the cloth from being overly driven to rotate, ensuring the smooth progress of the cloth supporting process.
