Please refer to FIG. 2 , which is a schematic view of the first embodiment of the ribbon clip of the present invention. As shown in Figure 2, the ribbon clip 2 proposed by the present utility model includes a bracket 28, and the bracket 28 includes a ribbon supply end 21 and a ribbon receiving end 22, wherein the ribbon supply end 21 includes a ribbon supply end The rotating shaft 211, the ribbon receiving end 22 includes a ribbon receiving end rotating shaft 221; wherein the ribbon receiving end rotating shaft 221 can only rotate in a single direction and cannot rotate in both directions.

Please refer to FIG. 3 , which is an exploded view of the rotating shaft 221 at the ribbon receiving end of the present invention. As shown in FIG. 3 , the rotating shaft 221 at the ribbon receiving end of the present invention includes a first actuating element 23 , a first elastic element 24 , a second actuating element 25 , a support shaft 26 and a second elastic element 27 . The first actuating element 23 includes a slot 231 , and the first end 261 of the supporting shaft 26 includes an oblique groove 2611 , and the second end 262 of the supporting shaft 26 is connected to the second elastic element 27 . In this embodiment, the inclined groove 2611 gradually extends toward the inside of the support shaft 26 along the counterclockwise direction, and the end of the inclined groove 2611 has a termination surface 26111 (please refer to FIG. terminal schematic). The second end 252 of the second actuating element 25 is designed as an inclined plane to facilitate sliding along the inclined groove 2611; wherein the slot 231 can provide a movement space for the second actuating element 25, and the first elastic element 24 can is a spring which provides the stress to displace the second actuating element 25 . The second elastic element 27 can provide buffer force.
