When the lower frame 3 and the upper frame 4 are combined, the lower frame 3 and the upper frame 4 can strengthen the connection between the two; a mounting groove 5 is provided on the side corresponding to the lower frame 3 and the upper frame 4; a positioning rod 6 is movably installed in the mounting groove 5, and one end extends out of the outside of the lower frame 3; a connecting groove 7 is provided on the surface of the positioning rod 6 near both ends; a connecting block 8 is fixed on the inner wall of the mounting groove 5, and corresponds to the unknown pair of connecting grooves 7. By assembling the connecting block 8 with the connecting groove 7, the positioning rod 6 is movably connected to the lower frame 3 and the upper frame 4. When fixing the embroidery cloth, the lower frame 3 and the upper frame 4 are separated, and the embroidery cloth is placed flat on the upper surface of the lower frame 3 so that both sides of the embroidery cloth are in contact with the positioning rod 6. The side of the upper frame 4 close to the mounting groove 1 5 is buckled with the lower frame 3 to fix the embroidery cloth. The lower frame 3 and the upper frame 4 are inserted into the positioning frame 1 to position the cloth. After the lower frame 3 and the positioning frame 1 are assembled, one side of the embroidery cloth is rolled up by rotating the positioning rod 6, so that the tension of the embroidery cloth is adjusted and the cloth is adjusted to a taut state. When the positioning rod 6 rotates, the connecting block 8 is always located inside the connecting groove 7 to restrict the connection of the connecting groove 7.

[0026] The limiting device is installed on the outer sides of the lower frame body 3 and the upper frame body 4 and can limit the positioning rod 6. The limiting device includes a second installation groove 11, a locking ring 12, a locking groove 13, and a compression spring 14. Among them, the second installation groove 11 is opened on the outer surfaces of the lower frame body 3 and the upper frame body 4. The locking ring 12 is inserted into the second installation groove 11 through a support rod, so that the locking ring 12 can move up and down along the second installation groove 11. The locking ring 12 is designed in a semi-circular shape, and a pawl is fixed on the inner wall.

Anti-slip teeth are also fixed on one side of the clamping plate 9 close to the anti-slip teeth of the clamping groove 10. When the lower frame body 3 and the upper frame body 4 are assembled, the clamping plate 9 is inserted into the clamping groove 10 correspondingly, so that the clamping plate 9 is stuck inside the clamping groove 10. Through the meshing of the anti-slip teeth of the clamping plate 9 and the clamping groove 10, the two groups of positioning rods 6 are connected to each other. When the positioning rod 6 is rotated, the two groups of positioning rods 6 can be rotated simultaneously by holding the outer wall of the clamping groove 10.

[0028] Working principle: Remove the upper frame body 4 and the lower frame body 3 from inside the positioning frame 1, disassemble the upper frame body 4 and the lower frame body 3 so that the embroidery cloth can be laid flat above the lower frame body 3. Confirm that both sides of the embroidery cloth are located on the upper surface of the positioning rods 6. Cover the upper frame body 4 above the lower frame body 3 again so that the clamping plate 9 is inserted into the clamping groove 10, so that the two groups of positioning rods 6 can move simultaneously. Clamp and fix the fabric through the lower frame body 3 and the upper frame body 4. Reinsert the combined upper frame body 4 and lower frame body 3 into the positioning frame 1. Move the locking ring 12 away from the positioning rods 6. Rotate one of the positioning rods 6 according to the tension of the embroidery cloth. Control the rotation of the positioning rod 6 through the clamping plate 9 so that the positioning rods 6 inside the upper frame body 4 and the lower frame body 3 can rotate simultaneously. When the positioning rod 6 rotates, it can wind up the embroidery cloth, and the embroidery cloth is wound around the surface of the positioning rod 6. The embroidery cloth wound around the surface of the positioning rod 6 is stored through the first mounting groove 5 to prevent the diameter of the positioning rod 6 from increasing too much. Widen the gap between the upper frame body 4 and the lower frame body 3. When the positioning rod 6 rotates a certain number of turns and the embroidery cloth is tight enough, push the locking ring 12 towards the positioning rod 6 through the second mounting groove 11. The pawl inside the locking ring 12 is inserted into the locking groove 13 on the surface of the positioning rod 6 to prevent the positioning rod 6 from reversing, ensuring the tightness of the embroidery cloth during embroidery and thus ensuring the quality of embroidery.
