[0018] Next, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0019] A circular arc surface thread holding device includes a semi-circular arc base 1, a plurality of clamping clips 2 are evenly arranged on the outside of the base 1, and a plurality of push rods 4 are evenly arranged on one side of the base. Each push rod 4 passes through the base 1 and is slidably connected to the base 1. One end of the push rod 4 is fixedly connected to the inner side of the clamping clip 2, and the other end is connected to an external pushing device (not shown in the figure); the surface thread is passed between the clamping clip 2 and the outside of the base 1;

[0020] That is, first, the push rod 4 is pushed forward by an external device, and then the upper thread is passed through the gap between the clamping clip 2 and the outer side of the base 1. The threading is simple and convenient, and the threading efficiency is high. After the threading is completed, the push rod 4 is pulled backward to fix the upper thread between the clamping clip 2 and the outer side of the base 1. It should be noted that the clamping clip 2 can clamp the upper thread to ensure that the upper thread can move in the vertical direction;

[0021] In this embodiment, ten clamping clips 2 are evenly arranged on the outside of the base 1;

[0022] In this embodiment, a mounting groove 3 is provided at the bottom of the base 1, the push rod 4 passes through the mounting groove 3, and a spring 5 passes through the upper end of the push rod 4, and a limit block 6 is fixedly provided on one side of the spring 5, the limit block 6 is fixedly connected to the push rod 4, and one end of the spring 5 is fixedly connected to the limit block 6, and the other end is fixedly connected to the side wall of the mounting groove 3; the spring 5 and the limit block 6 are both inside the mounting groove 3; that is, when threading is required, the external pushing device pushes the push rod 4 to move forward, and then the gap between the clamping clip 2 and the outer side of the base 1 becomes larger. After the needle thread is passed through, the external pushing device is released, and the clamping clip 2 can be retracted due to the elastic force of the spring 5 to fix the needle thread; it should be noted that the gap between the clamping clip and the outer side of the base 1 can be adjusted by controlling the elastic force of the spring 5, that is, by changing the elastic coefficient of the spring or lengthening the spring, etc., so that the gap between the clamping clip and the outer side of the base 1 can be controlled;

[0023] In this embodiment, a wire groove 7 is provided at the upper and lower ends of the middle of the clamping clip 2, and the wire groove 7 is used to pass the upper thread;

[0024] In this embodiment, a support block 11 is further fixedly provided on the outside of the base 1, and the clamping clip 2 is clamped on the support block 11; specifically, flanges 8 are provided at the upper and lower ends of both ends of the clamping clip 2, and the flanges 8 are located on both sides of the wire groove 7, and the flanges 8 are located on the upper and lower sides of the support block 11;

[0025] In this embodiment, a weight-reducing groove 10 is further provided on the side of the clamping clip 2;

[0026] In this embodiment, a groove 9 is provided on the outer side of the support block 11. The arrangement of the groove 9 reduces the contact area between the face thread and the outer side of the support block, thereby reducing the friction of the face thread and lowering the breakage rate of the face thread.

[0027] Compared with the prior art, the present invention avoids the entanglement of the upper threads by providing multiple clamping clips, and makes the clamping of the upper threads simpler and more stable by providing a push rod that is slidably connected to the base.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
