[0002] In the modern textile and garment industry, sewing machines play an important role. As one of the key components of sewing machines, the development of the sewing machine presser foot device has also gone through several stages. The early sewing machine presser foot device was relatively simple and had relatively single functions. With the continuous advancement of technology, today's sewing machine presser foot device is more sophisticated in design and can adapt to fabrics of different thicknesses and materials, improving sewing accuracy and efficiency.

[0003] However, in existing sewing machines, the presser foot device can only be used to sew by manually pressing the material, and during the sewing process, only one presser foot can be used for pressing. However, during the sewing process, multiple different seams may need to be sewn at the same time. Therefore, a sewing machine that can sew multiple positions at the same time during sewing is needed to meet the needs of users. Summary of the invention

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the object of the present invention is to provide a sewing machine presser foot device and a sewing machine, which can adjust the sewing position at a plurality of different angles and sew at multiple positions simultaneously.

[0005] To achieve the above object, the present invention provides the following technical solutions: A sewing machine presser foot device and a sewing machine, comprising a processing pad, a sewing machine body is mounted on the processing pad, a bracket is mounted on the processing pad in front of the sewing machine body, a fixing component for fixing cloth is mounted on the bracket, a presser foot is mounted on the sewing machine body, and a pressing component for driving the presser foot to move is provided on the sewing machine body.

[0006] The fixing assembly comprises a slide groove arranged on the bracket, and a first winding rod, a second winding rod and a third winding rod are slidably connected in the slide groove.

[0007] A first fastening bolt is installed on the first winding rod, a second fastening bolt is installed on the second winding rod, and a third fastening bolt is installed on the third winding rod.

[0008] A first fixing frame is fixedly connected to the processing pad, a first telescopic rod is installed on the first fixing frame, a cloth collecting roller is fixedly connected to the free end of the first telescopic rod, a slide rail is provided on the processing pad, and the cloth collecting roller is slidably connected to the slide rail.

[0009] The sewing machine body is connected with a rotating plate via a fourth telescopic rod, a plurality of needle holders are fixedly connected to the rotating plate, and a slot for installing a sewing needle is arranged in the needle holder.

[0010] The pressing assembly comprises a second telescopic rod fixedly connected to the first fixing frame, a fixing rod is installed on the second telescopic rod, and a plurality of third telescopic rods are installed on the fixing rod.

[0011] The presser foot is fixedly connected to the free end of the third telescopic rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the present invention can adjust the sewing position to a variety of different angles by driving multiple presser feet to move, and can arrange the fabric. By adjusting the position and arrangement of the presser feet and sewing needles, multiple positions can be sewn simultaneously, thereby ensuring that sewing can be more convenient.
