The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to specific circumstances.

Referring to fig. 1 to 7, as shown in the drawings, an embodiment of the present invention provides a self-winding reel 1, where the self-winding reel 1 includes a winding reel 11 and baffles 12 fixed at left and right ends of the winding reel 11, the self-winding reel 1 is provided with a rotating bobbin shaft 15, and two ends of the bobbin shaft 15 respectively pass through the baffles 12 and are rotatably connected with the baffles 12.
