The protection component 2 includes two pressing plates 21 and a first driving member 22, two connecting rods 23 and a second driving member 24. The two pressing plates 21 are respectively connected to the housing body 1 in a sliding manner in a vertical direction. The two pressing plates 21 are respectively located at the front and rear sides of the sewing needle 11. A moving plate 25 is connected to the workbench 12 in a sliding manner in a vertical direction. The moving plate 25 is located at the upper ends of the two pressing plates 21. The moving plate 25 is in a "return" shape. The first driving member 22 is used to drive the sliding of the moving plate 25. The two ends of the two connecting rods 23 are respectively connected to the two pressing plates 21 in a sliding manner in a horizontal direction. The sliding directions of the two connecting rods 23 are opposite. The second driving member 24 is used to drive the sliding of the two connecting rods 23.

[0031] Reference Figure 1-Figure 3 , a plurality of guide posts 212 are fixedly connected to the two pressing plates 21, and the ends of the plurality of guide posts 212 away from the pressing plates 21 are respectively penetrated and slidably connected to the moving plate 25, and the ends of the plurality of guide posts 212 penetrated the moving plate 25 are fixedly connected to the limiting block 213. When the two pressing plates 21 slide to the side away from the moving plate 25 to the limit position, the limiting block 213 abuts against the moving plate 25; the two pressing plates 21 are respectively limited by the connecting rod 23 and the plurality of guide posts 212, so that the moving distances of the two pressing plates 21 are consistent.

[0032] Reference Figure 1-Figure 3, and also includes multiple springs 26, the multiple springs 26 correspond to the multiple guide pillars 212, the multiple springs 26 are respectively mounted on the corresponding guide pillars 212, the two ends of the multiple springs 26 are respectively connected to the moving plate 25 and the pressure plate 21, and the first driving member 22 is used to drive the movement of the moving plate 25.

[0033] Reference Figure 1-Figure 3 By arranging the pressing plates 21 on the front and rear sides of the sewing needle 11, the pressing plates 21 can be used to press the parts of the garment that need to be sewn, making the use of the sewing machine more convenient; when the operator moves the garment, the pressing plates 21 reduce the possibility that the operator's hands enter the working area of ​​the sewing needle 11 during work, thereby reducing the possibility that the operator's hands are accidentally injured by the sewing needle 11 during work, thereby improving the safety of the sewing machine during use.

[0034] Reference Figure 1-Figure 3 The setting of the two connecting rods 23 can further press the position where the clothing needs to be sewn through the connecting rods 23, thereby reducing the possibility that the position where the clothing needs to be sewn will be spread apart when the clothing part moves under the sewing needle; and the setting of the connecting rods 23 can reduce the possibility that the operator's hands enter the working area of ​​the sewing needle 11 from both sides during work. The protective component 2 also includes two connecting rods 23 and a second driving member 24. The two ends of the two connecting rods 23 are respectively connected to the two pressing plates 21 in a horizontal direction for sliding. The sliding directions of the two connecting rods 23 are opposite. The second driving member 24 is used to drive the two connecting rods 23 to slide.

[0035] Reference Figure 1-Figure 3 The first driving member 22 drives the moving plate 25 to slide, so that the pressing plate 21 connected by the spring 26 moves together. When the pressing plate 21 abuts against the workbench 12, the first driving member 22 drives the moving plate 25 to continue moving, so that the spring 26 is compressed and deformed and generates a relative force to move the pressing plate 21 toward the side away from the moving plate 25, thereby pressing the clothes on the workbench 12. While the clothes can still be pressed, the possibility of being unable to move due to too much resistance is reduced.

[0036] Reference Figure 1-Figure 3 The two pressing plates 21 are movably connected to the side of the workbench 12 and the two connecting rods 23 are movably connected to the side of the workbench 12 with a plurality of balls 211. When the first driving member 22 drives the two pressing plates 21 to move to the side of the workbench 12 to the limit position, the plurality of balls 211 abut against the workbench 12. The possibility of excessive friction between the clothing and the connecting rod 23 and the pressing plate 21 after being pressed by the connecting rod 23 and the pressing plate 21 is reduced, so that the clothing can still be pressed, and the possibility of being unable to move due to too much resistance is reduced.

[0037] Reference Figure 1-Figure 3The second driving member 24 includes a threaded rod 241 and a force block 242. The two ends of the threaded rod 241 in the length direction have different thread rotation directions. The two ends of the threaded rod 241 in the length direction are respectively penetrated and threadedly connected to the two connecting rods 23. The force block 242 is fixedly connected to one end of the threaded rod 241 in the length direction. Applying force to the force block 242 causes the force block 242 to rotate, driving the threaded rod 241 to rotate. Through the connection between the threaded rod 241 and the two connecting rods 23, the two connecting rods 23 move along the axis direction of the threaded rod 241. The threaded rod 241 has different thread rotation directions at the two ends of the length, so that the two connecting rods 23 move in opposite directions.

[0038] Reference Figure 1-Figure 3 The first driving member 22 includes a threaded column 221 and a rotating cylinder 222. The rotating cylinder 222 is connected to the housing body 1 in a vertical direction. One end of the threaded column 221 is coaxially and threadedly connected to the rotating cylinder 222. The end of the threaded column 221 away from the rotating cylinder 222 is connected to the movable plate 25 in a vertical direction. The rotating cylinder 222 is rotated. Through the threaded connection between the rotating cylinder 222 and the threaded column 221, the threaded column 221 is moved along the axis direction of the rotating cylinder 222, so that the movable plate 25 connected to the threaded column 221 moves together. The movable plate 25 is also fixedly connected to a guide rod 243, which is slidably connected to the housing body 1 along the moving direction of the movable plate 25. The guide rod 243 plays a linear guiding role in the movement of the movable plate 25, so that the movable plate 25 can move in a linear direction.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
