[0025] Specifically, the frame 4 can be used to support the bottom of the operating table 2, and the hemming machine body 1 is installed on the guide plate 15. The use position of the hemming machine body 1 can be adjusted, thereby changing the position of the cloth hemming. The auxiliary part 7 can be connected to the guide frame 22 through the electric push rod 21. The electric push rod 21 can be used to adjust the distance between the auxiliary part 7 and the limiting plate 3, so as to control the clamping of the cloth. When the inner wall of the auxiliary part 7 overlaps with the cloth, the side of the cloth away from the limiting part 6 can be limited, thereby improving the consistency of the cloth moving with the limiting plate 3, so that the cloth is flattened on the top of the limiting plate 3, and the motor 9 can be used to provide power for the rotation of the lead screw 16, so that the guide frame 22 can move smoothly at the bottom of the operating table 2. Since the bottom of the limiting strip 12 is engaged with the limiting plate 3, when the auxiliary part 7 and the limiting strip 12 move with the guide frame 22, the limiting plate 3 also moves with the guide frame 22.
