By screwing the threaded shaft 5 into the first threaded hole on the base 6, the threaded shaft 5 can drive the expansion shaft 4 to move in position; allowing the user to adjust the position of the expansion shaft 4 according to needs.

[0020] The fixing assembly also includes multiple sets of sliding grooves; sliding grooves are provided on both sides of the mounting groove 8; sliders are provided on both sides of the fixing member 7; the sliders are slidably connected to the sliding grooves; a support frame 9 is provided on one side of the fixing member 7; through the sliding connection between the sliders and the sliding grooves, the fixing member 7 can move smoothly within the mounting groove 8; allowing the user to operate the fixing member 7 more smoothly; improving the smoothness of the cooperation between the various components of the device. The user can use the support frame 9 on one side of the fixing member 7 to provide a support point for the subsequent connection with the expansion shaft 4; enabling the device to move the fixing member 7 through the cooperation of the support frame 9 and the expansion shaft 4.

[0021] One end of the support frame 9 is provided with an inclined surface; the inclined surface is slidably connected to the expansion shaft 4; a return spring 10 is installed between one end of the fixing member 7 and the mounting groove 8; through the slidable connection between the inclined surface of the support frame 9 and the expansion shaft 4, the support frame 9 can be pushed to move the fixing member 7 when the expansion shaft 4 moves; so that the user can control the position of the fixing member 7 by moving the expansion shaft 4 and fix the device in the sewing machine mounting opening; the user can use the installation of the return spring 10 to make the fixing member 7 return to the initial position when it is not pushed by the expansion shaft 4; so that the device can restore the state of the fixing member 7.

[0022] The clamping assembly also includes an adjustment knob 11; the adjustment knob 11 is mounted on one end of the spindle; the outer side of the adjustment knob 11 is provided with anti-slip texture; the inner side of the adjustment knob 11 is provided with a second threaded hole; the anti-slip texture on the outer side of the adjustment knob 11 increases the friction when the user rotates the adjustment knob 11, allowing the user to hold and rotate the adjustment knob 11; the user can move the position of the adjustment knob 11 by engaging the external thread of the spindle 1 through the second threaded hole on the inner side of the adjustment knob 11; thus improving the ease of adjustment of the device.

[0023] The main spindle 1 has an external thread on its circumference; the external thread engages with the second threaded hole; an adjusting spring 12 is installed inside the adjusting knob 11; spring seats 13 are installed at both ends of the adjusting spring 12; one set of spring seats 13 is connected to the second clamping plate 3 on one side; the other set of spring seats 13 is connected to the adjusting knob 11 on one side; by setting the spring seats 13 at both ends of the adjusting spring 12, the elastic force of the adjusting spring 12 can be transmitted to the second clamping plate 3; allowing the user to change the deformation degree of the adjusting spring 12 by rotating the adjusting knob 11; thus improving the control effect of the device on the pressure of the second clamping plate 3. The user can rotate the adjusting knob 11 to change its position on the main spindle 1 by screwing the external thread of the main spindle 1 into the second threaded hole of the adjusting knob 11; thus allowing the device to compress or relax the adjusting spring 12 by moving the adjusting knob 11; thus improving the control effect of the device on the tension of the clamping space.

[0024] Please refer to, for example Figure 2 As shown, both the first thread clamping plate 2 and the second thread clamping plate 3 have several anti-slip raised fixing grooves on one side; anti-slip washers 14 are installed in the fixing grooves; a protective sleeve is provided on one side of the first thread clamping plate 2; the protective sleeve is slidably connected to the base 6; the installation of anti-slip washers 14 on the first thread clamping plate 2 and the second thread clamping plate 3 increases the friction force on the sewing thread; allowing the user to hold the sewing thread more stably in the clamping space; thus improving the device's clamping stability. The user can slide the protective sleeve on one side of the first thread clamping plate 2 to the base 6, allowing the protective sleeve to move with the first thread clamping plate 2; this allows the device to protect related components through the protective sleeve, improving the device's protective effect.

[0025] Two sets of locking blocks 15 are provided at one end of the main shaft; one side of each set of locking blocks 15 is connected to the adjustment knob 11. The connection between the two sets of locking blocks 15 and the adjustment knob 11 limits the rotation range of the adjustment knob 11 on the main shaft 1, preventing damage to components caused by excessive rotation of the adjustment knob 11 and improving the safety of the device. The user can limit the rotation of the adjustment knob 11 using the two sets of locking blocks 15, ensuring stability of the device during adjustment.

[0026] The specific usage and function of this embodiment are as follows: When using the device, the base 6 is placed into the mounting port of the sewing machine, and the threaded shaft 5 is rotated to engage and move within the first threaded hole of the base 6, driving the expansion shaft 4 towards the support frame 9. The expansion shaft 4 slides into contact with the inclined surface at one end of the support frame 9, pushing the support frame 9 to drive the fixing member 7 to slide along the groove of the mounting slot 8. One end of the fixing member 7 presses against the return spring 10. When the fixing member 7 contacts and abuts against the inner wall of the mounting port, the device is fixed. If disassembly is required, the threaded shaft 5 is rotated in the opposite direction, the expansion shaft 4 moves away from the support frame 9, the return spring 10 pushes the fixing member 7 to return to its original position, and the device can then be removed from the mounting port.

[0027] Next, adjust the tension of the sewing thread clamping mechanism. Rotate the adjusting knob 11 at one end of the main shaft 1. The adjusting knob 11 moves through the inner second threaded hole, engaging with the outer thread of the main shaft 1, compressing or releasing the inner adjusting spring 12. The elastic force of the adjusting spring 12 is transmitted to the second clamping plate 3 via the spring seat 13, changing the clamping force between the second clamping plate 3 and the first clamping plate 2, thereby adjusting the tension of the sewing thread within the clamping space. The two sets of locking blocks 15 limit the rotation range of the adjusting knob 11 to prevent over-adjustment and damage to components.

[0028] During sewing, the sewing thread passes through the clamping space between the first clamping plate 2 and the second clamping plate 3. The anti-slip washers 14 on both plates increase friction on the sewing thread, ensuring stable force distribution. The fixing plate secures the first clamping plate 2, maintaining its relative position to the second clamping plate 3 and ensuring a stable clamping space. The protective sleeve on one side of the first clamping plate 2 moves with it, protecting related components while maintaining a sliding connection with the base 6, thus not affecting overall operation.
