[0032] Reference Figure 2-Figure 4 , the left side of the electric turntable 5 is fixedly connected with a connecting component, the connecting component includes a fixed cylinder 6, the right side of the fixed cylinder 6 is fixedly connected to the left side of the electric turntable 5, a cylindrical groove 7 is opened on the right side of the fixed cylinder 6, the outer circumference of the fixed cylinder 6 is fixedly connected to a limited cylinder 11, and the limited cylinder 11 is provided with six groups, which are evenly distributed in a ring around the outer circumference of the limited cylinder 11, and the left side of the electric turntable 5 is fixedly connected with an electric push rod 8. The electric push rod 8 can accurately control the telescopic amount of the telescopic end. The electric push rod 8 is inside the cylindrical groove 7, and the left telescopic end of the electric push rod 8 is slidably connected to the inside of the fixed cylinder 6. The left telescopic end of the electric push rod 8 is fixedly connected with a sliding sleeve 9. When the electric push rod 8 is turned on, the left telescopic end of the electric push rod 8 will drive the sliding sleeve 9 to move left and right. The outer circumference of the sliding sleeve 9 is slidably connected to the outer circumference of the fixed cylinder 6, and the outer circumference of the sliding sleeve 9 is provided with a rounded groove 10. The rounded groove 10 is provided with six groups, which are evenly distributed in a ring around the sliding sleeve. The outer circumference of the movable sleeve 9 is slidably connected with a connecting component inside the rounded groove 10, and the outer circumference of the limiting cylinder 11 is slidably connected to the inside of the rounded groove 10. The rounded groove 10 limits the limiting cylinder 11 to slide left and right only along the inside of the rounded groove 10. The rounded groove 10 and the limiting cylinder 11 make the fixed cylinder 6 and the sliding sleeve 9 rotate in the same direction. A balancing groove 12 is opened on the outer circumference of the sliding sleeve 9, and a balancing protrusion 13 is fixedly connected to the outer circumference of the connecting component. The balancing protrusion 13 is fixedly connected to the outer circumference of the fixed cylinder 6. The inner wall of the side surface of the balancing groove 12 and the outer wall of the side surface of the balancing protrusion 13 are at the same distance from the center of the circle, so that the bottom of the balancing groove 12 and the outer circumference of the balancing protrusion 13 are in the same plane in the horizontal direction, and the outer circumference of the balancing protrusion 13 and the inner wall of the bottom surface of the balancing groove 12 are fixedly connected with hinge blocks 14. The hinge blocks 14 are provided in six groups, each group is provided with two blocks, and are evenly distributed in an annular manner on the outer circumference of the balancing groove 12 and the balancing protrusion 13.

[0033] Reference Figure 3 A scissor arm 15 is hinged on the outside of the hinge block 14. The rotation of the scissor arm 15 can drive the inner and outer ends to extend and retract. Two groups of scissor arms 15 are provided, which are symmetrically arranged on both sides of the hinge block 14, and the two hinge blocks 14 opposite to each other on the left and right are connected at the same time. The outer side of the scissor arm 15 is rotatably connected to a rotating wheel 16, and the outer periphery of the rotating wheel 16 is slidably connected to an opening component, and the opening component includes a sliding seat 17. The sliding seat 17 limits the rotating wheel 16 from sliding left and right along the inside of the sliding seat 17. The inside of the sliding seat 17 is slidably connected to the outer periphery of the rotating wheel 16. A support plate 18 for supporting the storage bag is fixedly connected to the outside of the sliding seat 17, and a sewing groove 19 for convenient sewing is provided on the outer side of the right end of the support plate 18.

[0034] Reference Figure 4 A T-slot 20 is provided on the left side of the electric turntable 5. Six groups of T-slots 20 are arranged, which are evenly distributed in a ring shape on the left side of the electric turntable 5. The position of the T-slot 20 is opposite to the position of the support plate 18. The outer side of the T-slot 20 is elastically connected to a clamping block 22 through a return spring 21. When the clamping block 22 is not subjected to force, the return spring 21 will push the clamping block 22 inward. One end of the return spring 21 is fixedly connected to the outer side of the T-slot 20, and the other end of the return spring 21 is fixedly connected to the outer side of the clamping block 22. The clamping block 22 is slidably connected to the inside of the T-slot 20, and the T-slot 20 limits the clamping block 22 to slide only along the inner wall of the T-slot 20. The bottom end of the clamping block 22 is fixedly connected to a clamping base pad 23, and the clamping base pad 23 is made of elastic silicone with strong friction on the surface. The inner side of the clamping base pad 23 contacts the outer side of the support plate 18. When the support plate 18 shrinks to the minimum, it is on the inner side of the clamping base pad 23 and does not contact the clamping base pad 23. When the storage bag is placed on the support plate 18, the outer edge of the storage bag can be clamped.

[0035] Working principle: when you want to open the storage bag conveniently, put the storage bag on the outside of the support plate 18, turn on the electric push rod 8, the electric push rod 8 pushes the sliding sleeve 9 to the right, the sliding sleeve 9 drives all the hinge blocks 14 on the left side to move to the right, the distance between the hinge blocks 14 on the left and right sides is reduced, and the scissor arms 15 are driven to open outwards, the scissor arms 15 drive the rotating wheels 16 to slide inwards along the sliding seat 17, and at the same time drive the support plate 18 to open, so as to open the storage bag and support the storage bag. At this time, adjust the position of the sewing machine 3, turn on the sewing machine 3 and the electric turntable 5, and then the edge of the storage bag can be sewed. When you want to conveniently clamp and fix the edge of the storage bag, first turn on the electric push rod 8 to move the telescopic end of the electric push rod 8 to the left, so that the support plate 18 shrinks to the minimum. At this time, the support plate 18 puts the storage bag on the support plate 18 again, and then turn on the electric push rod 8 to open the support plate 18. The support plate 18 moves outward to make the edge of the storage bag contact with the clamping base pad 23, and the support plate 18 continues to move outward. At this time, the support plate 18 pushes the clamping block 22 to move outward and compresses the reset spring 21. The reset spring 21 applies pressure to the inside, so that the clamping base pad 23 clamps the storage bag.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
