[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] To facilitate flexible height adjustment of the clamp, making it suitable for users of different heights, it is combined with the attached... Figure 1 Appendix Figure 2 and attached Figure 4 A garment sewing clamp includes a base 1, with support frames 2 on both sides of the base 1, and support columns 3 at the top of each support frame 2. It also includes extension columns 4; two extension columns 4 are respectively inserted into the support columns 3, each extension column 4 having a T-shaped cross-section. Each support column 3 has a T-shaped groove 5 for use with the extension columns 4, and a locking structure is provided between the support columns 3 and the extension columns 4. The locking structure includes studs 6 and first knobs 7; two studs 6 are threaded to one side of the support column 3, one end of each stud 6 extending into the T-shaped groove 5 and contacting the extension column 4, and two first knobs 7 are respectively located at the other end of each stud 6.

[0027] By loosening the first knob 7, the stud 6 is moved away from the extension column 4. At this time, the extension column 4 can slide up and down along the T-shaped slide groove 5 to adjust its height. After adjusting to the target height, tighten the first knob 7 so that the stud 6 presses against the extension column 4, and the height of the extension column 4 is locked by friction.

[0028] To facilitate flexible adjustment of the tilt angles of the outer fixing ring 9 and the inner fixing ring 11 to adapt to different sewing needs, combined with the attached... Figure 1 Appendix Figure 3 and attached Figure 5 Each of the extension columns 4 has a rotating shaft 8 on opposite sides, with an outer fixing ring 9 positioned between the rotating shafts 8. An L-shaped plate 10 is located on one side of the outer fixing ring 9, and an inner fixing ring 11 is embedded within the outer fixing ring 9 on one side of the L-shaped plate 10. An angle adjustment assembly for use with the outer fixing ring 9 is located on one side of the rotating shaft 8. The outer fixing ring 9 has an opening, within which a fastening structure for mutual cooperation is provided. The angle adjustment assembly includes a worm gear 15 and a worm 17; the worm gear 15 is located on one side of the rotating shaft. On the 8, a concave plate 16 is provided on one side of the extended column 4 and below the worm gear 15. The worm 17 is rotatably disposed in the concave plate 16 and meshes with the worm gear 15. A second knob 18 is provided at one end of the worm 17 extending outside the concave plate 16. The fastening structure includes a connecting plate 12, a fastening bolt 13 and a locking nut 14. The two connecting plates 12 are disposed on both sides of the opening of the outer fixing ring 9. The fastening bolt 13 passes through the two connecting plates 12 in sequence, and the locking nut 14 is threadedly connected to the other end of the fastening bolt 13.

[0029] When the second knob 18 is turned, the worm gear 17 drives the worm wheel 15 to rotate, which in turn drives the outer fixed ring 9 and the inner fixed ring 11 to rotate through the rotating shaft 8, thereby realizing the adjustment of the clamping angle. After the target angle is adjusted, the self-locking property of the worm wheel and worm gear can keep the angle stable without the need for an additional locking structure.

[0030] In specific implementation of this utility model:

[0031] First, place the fabric between the inner fixing ring 11 and the outer fixing ring 9, and turn the locking nut 14 to bring the two connecting plates 12 closer to each other. The opening of the outer fixing ring 9 will narrow, and the inner fixing ring 11 and the outer fixing ring 9 will clamp the fabric together.

[0032] Next, loosen the first knob 7 on both sides of the support column 3 to move the stud 6 away from the extension column 4. At this time, the extension column 4 can slide up and down along the T-shaped slide groove 5. After adjusting to the target height, tighten the first knob 7 to make the stud 6 press against the extension column 4, and achieve height locking of the extension column 4 through friction.

[0033] During the sewing process, turning the second knob 18 rotates the worm gear 17, which engages with the worm wheel 15, thereby rotating the shaft 8 and the outer fixing ring 9. After adjusting to the target angle, the self-locking property of the worm wheel and worm gear keeps the angle stable without the need for an additional locking structure. This allows for flexible adjustment of the clamp height, adapting to the operating habits of operators of different heights, reducing the risk of occupational injury, and enabling precise adjustment and locking of the clamping angle to meet the sewing angle requirements of different parts of the garment, reducing the number of times the fabric is disassembled and reassembled.
