The socks are leaned against and stuck into the lower part of the elastic positioning strip 12, and the socks are initially positioned by the elastic positioning strip 12; a plurality of lower bottom plates 5 corresponding to the sewing notches 3a are also installed on the placement plate 3, and the lower bottom plates 5 are connected to the upper top plate 9 through guide columns 11, and a middle movable plate 10 is also slidably connected to the guide columns 11, and a cylinder 8 is installed on the upper top plate 9, and the piston rod of the cylinder 8 is vertically downward, and the end of the piston rod of the cylinder 8 is connected to the middle movable plate 10, and a pressing piece 7 for pressing the socks is connected to the middle movable plate 10. After the socks are initially positioned, the piston rod of the cylinder 8 moves downward, and the piston rod of the cylinder 8 drives the middle movable plate 10 to move downward, and the middle movable plate 10 drives the pressing piece 7 to move downward, and the pressing piece 7 presses the outer edge portion of the socks where the socks need to be sewn, so that the placement plate 3 can drive the socks to rotate and move them to the sewing machine.

[0018] The driving structure includes a stepper motor 17, a synchronous wheel 16, a synchronous wheel 2 14 and a synchronous belt 15. The stepper motor 17 is installed on the mounting frame 13 through a connecting plate 18, and the output shaft of the stepper motor 17 is vertically upward.
