Two electric push rods 6 are installed on the upper surfaces of the two T-shaped blocks 5 , and the output ends of the electric push rods 6 are fixedly connected to the bottom surface of the support plate 201 .

[0028] The T-shaped block 5 can slide on the upper surface of the base plate 4, and the four electric push rods 6 are electrically connected to the same controller, so as to realize synchronous control of the four electric push rods 6. Through the electric push rods 6 installed on the T-shaped block 5, the height of the manual embroidery auxiliary device can be adjusted to adapt to the use of people of different heights.

[0029] A second servo motor 7 is installed on the upper surface of the base plate 4. The two output shaft ends of the second servo motor 7 are fixedly connected with second screws 8. The second screws 8 are threadedly connected to the T-shaped block 5. The base plate 4 fixes and limits the second servo motor 7. After the second servo motor 7 is started, it can drive the two second screws 8 to rotate synchronously in the forward and reverse directions. The two second screws 8 drive the two T-shaped blocks 5 to move closer to or away from each other, thereby realizing the folding and unfolding of the hand embroidery auxiliary device, making it more stable when used.

[0030] Two symmetrical fixing plates 9 are fixedly connected to the upper surface of the bottom plate 4. The two fixing plates 9 are rotatably connected to the two second screw rods 8 respectively.

[0042] Working principle: When using the embroidery auxiliary device for hand embroidery, first move it to the use position, then adjust the device according to the size of the cloth to be embroidered, pull the two support plates 201 away from each other, so that the connecting frame 1 is gradually unfolded, and at the same time, the circular blocks connected to the bottom ends of the two pins on the connecting frame 1 slide in the convex reserved grooves in the support plates 201 until the spacing between the two support plates 201 is adjusted to a suitable distance, and then the two sliders 207 located at the top slide to a suitable position, and then place the upper corner of the cloth to be embroidered between the rotating plate 202 and the clamping plate 209, and then rotate the bolt 208 to drive the clamping plate 209 to gradually approach the rotating plate 202, so as to limit and fix the upper corner of the cloth to be embroidered, and refer to the above operation method to limit and fix the other upper corner of the cloth to be embroidered, and then according to the width of the cloth with embroidery, move the two sliders 207 located at the bottom. After the two support plates 201 are moved away from each other, the embroidery cloth is tightened, and then the positions of the two support plates 201 are fixed, thereby fixing the embroidery cloths of different sizes. At the same time, the two first servo motors 203 can be controlled to start synchronously to drive the first screw rod 204 to rotate. The first screw rod 204 drives the hinge block 205 thereon to slide along the upper surface of the support plate 201. Then, the hinge block 205 drives the rotating plate 202 to rotate with the hinge point between the support plate 201 and the rotating plate 202 as the center of the circle through the hinge rod 206 hinged thereto, thereby adjusting the angle of the embroidery cloth fixed by the upper limit of the rotating plate 202. After use, the limit of the embroidery cloth can be released, and the embroidery auxiliary device for hand embroidery can be folded and stored to reduce the space occupied and facilitate subsequent storage and transportation.
