[0030] As an embodiment of the present invention, the notch is a through notch, which penetrates along the thickness direction of the bobbin fixing plate 301; the buckle claw includes a buckle plate 401 and a transmission rod 402, the lower end of the buckle plate 401 is fixedly connected to one end of the transmission rod 402, and the lower end of the buckle plate 401 is hinged at the through notch. At the same time, the transmission rod 402 is located in the notch, and the upper end of the buckle plate 401 extends out of the bobbin mounting seat 3, so that the bobbin can be pressed and positioned;

[0031] The transmission assembly includes a push rod sleeve 403, which is sleeved on the transmission rod 402. The push rod sleeve 403 is slidably connected to the transmission rod 402, and the transmission rod 402 can slide in the push rod sleeve along the length direction of the transmission rod 402. The lower end of the push rod sleeve 403 is hinged with a push rod 404, which is vertically arranged. The lower end of the push rod 404 is fixedly connected with a fixing rod 405, which is horizontally arranged. A first spring 410 is arranged between the fixing rod 405 and the bottom surface of the spool fixing plate 301, and the first spring 410 has a restoring force when compressed. The right end of the fixing rod 405 is fixedly connected with a sleeve 406, which is sleeved on the outer wall of the bearing sleeve 302 of the spool mounting seat 3 and is slidably connected to the bearing sleeve 302. When the fixing rod 405 moves vertically, it can drive the buckle claw to work;

[0032] The control assembly includes a spur rack 407, which is fixedly connected to the outer wall of the sleeve 406 and extends along the axial direction of the sleeve 406. A lever 408 is provided on one side of the sleeve 406.

At the same time, the vertical movement of the sleeve 406 can be controlled by flipping the lever 408.

[0033] Initially, the pressing plate 401 is in a state of pressing and fixing the spool 7. When a new spool 7 needs to be installed or replaced, the lever 408 is pushed downward, the sector gear 409 rotates counterclockwise, the spur rack 407 is pushed upward, the sleeve 406 moves upward under the drive of the spur rack 407, and the fixing rod 405 moves upward under the drive of the sleeve 406. At this time, the first spring 410 located between the fixing rod 405 and the spool fixing plate 301 is compressed, the push rod 404 moves upward under the push of the fixing rod 405, and the push rod sliding sleeve 406 moves upward. 3 is pushed upward by the push rod 404, and the position where the push rod sliding sleeve 403 contacts the transmission rod 402 is pushed upward. Since the lower end of the pressing plate 401 is fixedly connected to one end of the transmission rod 402, and the lower end of the pressing plate 401 is hinged at the notch, the transmission rod 402 rotates counterclockwise around the hinge point, and the pressing plate 401 rotates counterclockwise under the drive of the transmission rod 402, releasing the pressing and fixing of the bobbin 7. When replacing, the old bobbin is removed, the new bobbin is installed, and then the lever 408 is released, and the pressing plate 401 presses and fixes the bobbin 7 again;

[0034] As another embodiment of the utility model, the transmission assembly and the control assembly in the above embodiment are partially improved. In this case, the notch is a half-open notch, the upper end of the half-open notch is open and the lower end is closed, and the lower end of the buckle plate is hinged at the opening of the half-open notch;

[0035] The transmission assembly includes a slide bar 501, which is hinged at the right end of the transmission rod 402. The slide bar 501 is a transversely arranged straight rod. A spring sleeve 502 is sleeved on the slide bar 501. The slide bar 501 can slide in the spring sleeve 502 along the length direction of the slide bar 501. The upper end of the spring sleeve 502 is fixedly connected to a pressing contact 503. When no spool is placed on the spool fixing disk 301, the upper end surface of the pressing contact 503 protrudes from the upper surface of the spool fixing disk 301. When a spool is placed on the spool fixing disk 301, the lower end surface of the spool will press the pressing contact 503 downward, and the upper end surface of the pressing contact 503 will be flush with the upper surface of the spool fixing disk 301. The lower end of the spring sleeve 502 is fixed A second spring 504 is connected, and the second spring 504 has a restoring force when compressed. The lower end of the second spring 504 is fixedly connected to the closed bottom surface of the half-open notch. A guide rod 505 is inserted in the middle of the second spring 504. The guide rod 505 is a vertically arranged straight rod. The upper end of the guide rod 505 is fixedly connected to the spring sliding sleeve 502. A guide rod hole is provided on the closed bottom surface of the half-open notch. The guide rod 505 passes through the guide rod hole and is fixedly connected to a cross bar 506 outside the bobbin fixing disk 301. The cross bar 506 is a hard rigid straight rod. The right end of the cross bar 506 is fixedly connected to a hook rod 507. The hook rod 507 is a vertically arranged straight rod. A first buckle hook 508 is provided at the lower end. The upper surface of the first buckle hook 508 is a plane, and the lower surface is a circular arc surface.

[0036] The control component includes a second hook 509, which is arranged on the bearing sleeve 302. The upper surface of the second hook 509 is an arc surface, and the lower surface is a plane. When the spool 7 is placed on the spool fixing plate 301, the lower surface of the second hook 509 is pressed against the upper surface of the first hook 508. Since the lower surface of the second hook 509 and the upper surface of the first hook 508 are both planes, they will remain pressed against each other and will not separate. The lower end of the second hook 509 is fixedly connected with a button 510, and the right end of the button 510 is provided with a third spring 511. The third spring 511 has a restoring force when compressed, and the right end of the third spring 511 is fixedly connected to the bearing sleeve 302;

[0037] Initially, the pressing plate 501 is in a state of pressing and fixing the spool 7. At this time, the upper end surface of the pressing contact 503 is flush with the upper surface of the spool fixing plate 301, and the second spring 504 is in a compressed state. When a new fine wire spool 7 needs to be installed or replaced, the button 510 is pressed, and the third spring 511 is in a compressed state. At the same time, the second hook 509 will be separated from the first hook 508, and the first hook 508 will move upward due to the loss of the resistance force of the second hook 509. The second spring 504 has a restoring force due to compression, which will push the sliding sleeve to move upward, and the upward movement of the sliding sleeve will push the sliding rod 501 to move upward, and the upward movement of the sliding rod 501 will The transmission rod 502 is driven to move, and the movement of the transmission rod 502 will drive the pressing plate 501 to move. Since the pressing plate 501 is hinged at the opening of the half-open notch, the pressing plate 501 will rotate around the hinge point, so that the buckle claw is separated from the spool 7. When the buckle claw is separated from the spool 7, the pressing contact 503 bounces upward under the action of the restoring force of the second spring 504, so that the spool 7 is separated from the spool fixing plate 301. At this time, the upper end surface of the pressing contact 503 is located above the upper surface of the spool fixing plate 301. When a new spool is replaced, the new spool will press the pressing contact 503 when it is placed on the spool fixing plate 301, so that the buckle claw presses and fixes the new spool again;

[0038] In this embodiment, it is convenient and quick to connect the spool to the spool fixing disk.
