Driving the movable seat 62 to move on the support frame 4 by the third driving component 7 can drive the support rods 64, the adapter seats 63 and the support plates 65 to act, so as to unfold or fold up the folding bracket 6, and adjust the height and inclination angle of the folding bracket 6 by lifting the lifting frame 2 on the base 1 and rotating the support frame 4 on the lifting frame 2. Pressing components 8 are respectively provided on the support plates 65. The pressing components 8 are used for clamping the fabric after the folding bracket 6 is unfolded to fix the fabric on the folding bracket 6.

[0017] Specifically, the operating steps for fixing the fabric using the folding embroidery frame provided in this embodiment are as follows: First, unfold the folding frame. Operate the third driving component 7 to drive the movable seat 62 to move on the support frame 4 in the direction close to the fixed seat 61. The support rod 64 rotates as the movable seat 62 moves and lifts the adapter block. At the same time, the support plate 65 slides and rotates on the support rod 64 until the movable seat 62 moves to a position where the four support plates 65 enclose a square shape, then the folding frame 6 can be unfolded. Clamp the fabric through the pressing component 8 to fix the fabric on the folding frame 6 and keep the fabric taut. And operate the first driving component 3 to drive the lifting frame 2 to move up and down on the base 1 to adjust the height where the folding frame 6 is located. Operate the second driving component 5 to drive the support frame 4 to rotate on the lifting frame 2 to adjust the inclination angle of the folding frame 6, so as to facilitate the user to adjust the folding frame 6 to a suitable position. After the adjustment is completed, embroidery can be performed on the fabric. When it is necessary to fold the folding embroidery frame, first operate the first driving component 3 and the second driving component 5 to lower the lifting frame 2 to the lowest position and lay the support frame 4 flat. Then operate the third driving component 7 to drive the movable seat 62 away from the fixed seat 61. As the movable seat 62 moves, the support rod 64, the adapter block and the support plate 65 act synchronously. As the support rod 64 rotates, the adapter block descends to a position where it fits with the support frame 4. At the same time, the four support plates 65 slide and rotate on the support rod 64 respectively until the support plates 65 are spliced into a flat plate, then the folding frame 6 can be folded to reduce the volume of the folding embroidery frame. The folding embroidery frame provided in this embodiment can fold the folding frame 6 when it is idle or in transportation to reduce the occupied space, thereby facilitating the storage or handling of the folding embroidery frame.
