DETAILED DESCRIPTION

[0017] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0018] A typical embodiment of the present invention provides an auxiliary positioning mechanism, such as Figure 3 As shown, it includes a fixed plate 201, a motor 204 is fixedly arranged at the front position of the upper end of the fixed plate 201, and a plurality of fixed blocks 205 are fixedly arranged at the middle and rear positions of the upper end of the fixed plate 201; a rotating shaft 206 is arranged on the outer side of the fixed block 205, and the rotating shaft 206 and the output end of the motor 204 are fixedly connected with pulleys 207, and the pulleys 207 are connected by a transmission belt 208, and a fixed column 209 is fixedly arranged on the outer side of the pulley 207, and a conveyor belt 210 is wrapped around the outer surface of the fixed column 209.

[0019] The auxiliary positioning mechanism 2 provided in this embodiment can be used on different types of sewing machines 1. After the auxiliary positioning mechanism 2 assists in positioning the cloth, it can drive the cloth to move forward and backward by its own rotation, thereby reducing friction with the cloth and reducing damage to the cloth.

[0020] In this embodiment, the fixing plate 201 is used to install and fix the motor 204. The motor 204 drives the pulley 207 to rotate. When the motor 204 is turned on, the motor 204 drives the pulley 207, the fixing column 209 and the conveyor belt 210 to rotate. When the conveyor belt 210 rotates, it drives the cloth forward.

[0021] like Figure 3 As shown, telescopic rods 202 are arranged on both sides of the lower end of the fixing plate 201, and magnetic plates 203 are fixedly arranged at the lower ends of the telescopic rods 202. Figure 4 As shown, a magnetic block 216 is fixedly provided at the bottom of the magnetic plate 203. The telescopic rod 202 is an electric telescopic rod, which can be adjusted in height according to the different thicknesses of the fabrics, such as Figure 1 or Figure 2 As shown, the auxiliary positioning mechanism 2 can be magnetically fixed to the sewing machine 1 using the magnetic block 216, and the fixing position of the auxiliary positioning mechanism 2 can be adjusted as needed.

[0022] This embodiment provides another fixing method, such as Figure 3 As shown, a bolt 213 is provided on the magnetic plate 203 , and the auxiliary positioning mechanism 2 and the sewing machine 1 can also be fixed by the bolt 213 .
