[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0025] This utility model embodiment provides an embroidery frame with a clamping device, such as Figure 1-6 As shown, it includes an embroidery frame base 1 and a clamping device 2. The clamping device 2 is mounted on the top of the embroidery frame base 1 via a connector 3.

[0026] like Figure 1 As shown, the embroidery frame base 1 includes a base plate 11 and a support frame 12. The base is a horizontally arranged base plate 11 with a wide and flat shape, which lowers the center of gravity and makes the operator more stable during operation.

[0027] A support frame 12 is mounted on the chassis 11. The support frame 12 is cylindrical in shape and divided into multiple segments. The inner diameter of each segment can be the same or different. The cylindrical surface provides a better grip for the user. An installation opening 31 is provided at the top of the support frame 12, and the connector 3 is inserted into the installation opening 31. Rotating handles 4 are provided on both sides of the support frame 12. The rotating handles 4 pass through the support frame 12 and fix the connector 3 to the support frame 12. The rotating handles 4 are threadedly connected to the support frame 12 and the connector 3. By tightening or loosening the rotating handles 4, the fixing angle of the clamping device 2 can be easily adjusted. The clamping device 2 can easily achieve different suspension angles, such as the common 30° and 45°, thereby achieving tilt angle adjustment to meet the comfort needs of different embroiderers.

[0028] Furthermore, the connector 3 is threadedly connected to the clamping device 2, and the surface of the clamping device 2 is provided with a threaded hole. The top of the connector 3 can be directly connected to it through the threaded hole, which facilitates the installation and disassembly of the clamping device 2 and improves the flexibility and maintainability of the embroidery frame.

[0029] like Figure 2-4The clamping device 2 includes a clamping component and an operating component, wherein the clamping component is pushed by the operating component to generate displacement, and the two together clamp and fix the embroidery frame.

[0030] One end of the clamping member is provided with a clamping column 21, and the other end is provided with a first clamping crossbar 22. The operating member includes a second clamping crossbar 23 and a displacement part. A gap is provided between the clamping column 21 and the first clamping crossbar 22. The second clamping crossbar 23 is disposed between the clamping column 21 and the first clamping crossbar 22 and is pushed by the displacement part to move between the clamping column 21 and the first clamping crossbar 22.

[0031] The displacement unit includes a handle 24 and a push rod 241. The handle 24 is located outside the column and the first clamping crossbar 22. The push rod 241 is fixedly connected to and passes through the first clamping crossbar 22. One end of the push rod 241 is connected to the second clamping crossbar 23, and the other end is connected to the handle 24. By rotating the handle 24, the push rod 241 pushes the second clamping crossbar 23 to move under the action of the thread, thereby clamping or releasing the embroidery frame.
