[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Refer to Figure 1-4 An embroidery machine with easy-to-change embroidery heads includes a needle bar 1 and an embroidery needle head 4. The bottom of the needle bar 1 is provided with a mounting groove 6, and the end of the embroidery needle head 4 is provided with a mounting end 5. The mounting end 5 is installed in the mounting groove 6. A connecting frame 2 is fixedly installed on one side of the needle bar 1, and a drive presser foot 3 is fixedly installed on one end of the connecting frame 2. The drive presser foot 3 is a ring structure with the mounting end 5 on the embroidery needle head 4 installed on the needle bar 1. By moving up and down on the needle bar 1, the embroidery thread is passed through the embroidery needle head 4, which can achieve the embroidery effect on the fabric. The drive presser foot 3 can press the fabric tightly to achieve a stable embroidery effect.

[0021] Specifically, a movable groove 7 is provided on the outer side of the needle rod 1, and a spiral extrusion assembly is provided in the movable groove 7. A clamping assembly is installed in the needle rod 1, and the clamping assembly is adapted to the mounting end 5. The spiral extrusion enables the clamping assembly to move. The spiral extrusion assembly includes a connecting thread 8 formed on the surface of the movable groove 7. A nut 9 is threadedly installed on the movable groove 7. An arc-shaped extrusion surface 10 is formed on one side of the nut 9. An arc-shaped extrusion groove 17 is formed on one side of the movable pressure rod 13, and the arc-shaped extrusion groove 17 is adapted to the arc-shaped extrusion surface 10. During the embroidery process, the embroidery needle 4 needs to be replaced to meet different embroidery needs. When replacing, the worker rotates the nut 9 on the spiral compression assembly. After the nut 9 rotates, it will move upward and separate from the moving pressure rod 13. Under the elastic force of the compression spring 15, it will drive the arc-shaped pressure plate 16 to move into the pressure plate placement groove 18. The arc-shaped pressure plate 16 will no longer compress the installation end 5. At this time, the embroidery needle 4 can be removed by pulling it down and replaced with a new embroidery needle 4, thus realizing the replacement of the embroidery needle 4.

[0022] Specifically, the extrusion assembly includes a pressure plate placement groove 18 formed on the inner wall of the mounting groove 6. An extrusion groove 11 is formed on the inner wall of the pressure plate placement groove 18, and the extrusion groove 11 is connected to the moving groove 7. A movable pressure rod 13 is movably installed within the extrusion groove 11, with both ends of the movable pressure rod 13 extending outside the extrusion groove 11. An arc-shaped clamping plate 16 is fixedly installed at one end of the movable pressure rod 13. The arc-shaped clamping plate 16 is located within the pressure plate placement groove 18 and is adapted to the mounting end 5. Limiting grooves 12 are formed on the inner walls of both sides of the extrusion groove 11. Limiting blocks 14 are fixedly installed on both sides of the movable pressure rod 13. The limiting blocks 14 are slidably installed within the limiting grooves 12, and the sides of the limiting blocks 14 are flush with the sides of the limiting grooves 12. A compression spring 15 is fixedly installed between the walls. After replacing the new embroidery needle 4, the nut 9 is rotated in the opposite direction again. As the nut 9 moves downward, it will contact and compress the moving pressure rod 13 on the pressing assembly. Under the action of the arc-shaped pressure groove 17 and the arc-shaped compression surface 10, the moving pressure rod 13 can be moved. The moving pressure rods 13 on both sides move closer to each other, thereby driving the arc-shaped pressing plate 16 to press the mounting end 5. The embroidery needle 4 can be replaced by pressing on both sides. During the replacement process, only the nut 9 needs to be rotated. There is no need to use disassembly tools to remove the screws, making the replacement relatively convenient. The limiting groove 12 and the limiting block 14 can limit the position of the moving pressure rod 13.

[0023] In use: The mounting end 5 of the embroidery needle 4 is mounted on the needle bar 1. By moving the needle bar 1 up and down, the embroidery thread is passed through the embroidery needle 4, which can achieve the embroidery effect on the fabric. When replacing the embroidery needle 4, the operator rotates the nut 9 on the spiral pressing assembly. The nut 9 separates from the moving pressure rod 13, and the arc-shaped pressing plate 16 no longer presses the mounting end 5. At this time, the embroidery needle 4 can be removed by pulling it down. After replacing it with a new embroidery needle 4, the nut 9 is rotated in the opposite direction again. During the downward movement of the nut 9, it will come into contact with the moving pressure rod 13 on the pressing assembly and press it, causing the arc-shaped pressing plate 16 to press the mounting end 5. Through the pressing on both sides, the embroidery needle 4 can be replaced. During the replacement process, only the nut 9 needs to be rotated. There is no need to use disassembly tools to remove the screws, making the replacement relatively convenient.
