Referring to FIGS. 8A to 8F together, the operation of the elastic positioning member 2 and the annular guide 52 of the cord reel assembly 100 of the present invention is shown. As can be seen from the figure, the positioning of the elastic positioning member 2 is shown. The post 21 is embedded in the annular guide 52. When the user pulls the transmission line 7 counterclockwise from the reel assembly 100, the rotating base 5 also rotates counterclockwise, so that the annular guide 52 also rotates counterclockwise, thereby driving the elastic positioning member 2 to slide in a rectangular shape. The slot 12 is displaced, and the position of the positioning post 21 is changed with respect to the rotating base 5, as shown in FIG. 8F, which is the relative position of the elastic positioning member 2 and the annular guide 52, and is sequentially rotated to 0 degrees (clamping position). ), 180 degrees, 270 degrees, 360 degrees, 450 degrees and 630 degrees, and finally return to the initial stuck position. It can be seen that when the transmission line 7 is pulled outward, the rotary base 5 starts to rotate counterclockwise, at which time the elastic positioning member 2 starts to rotate clockwise from the stuck position to the outer ring of the annular guide 52, when the rotary base 5 rotates. At 270 degrees, the elastic positioning member 2 starts to rotate clockwise from the outer ring through the guide rail connecting the outer ring and the inner ring to the inner ring of the annular guide 52, and then the elastic positioning member 2 rotates clockwise on the inner ring until the transmission line 7 is fully Pull out. On the contrary, when the outward pulling of the wire is stopped, the rotating base 5 starts to rotate clockwise due to the restoring force of the swirling spring 6, and if the elastic positioning member 2 is at the inner ring of the annular guide 52, the elastic positioning member 2 is along The inner ring is turned counterclockwise back to the stuck position. If the elastic positioning member 2 is on the outer ring of the annular guide 52 at this time, the elastic positioning member 2 is rotated counterclockwise back along the outer ring to the stuck position, and the spirally connected ring is passed. The guiding action of the guide rail 52 and the step, and the elastic deformation of the base portion 22 of the elastic positioning member 2, finally realize the movement and positioning of the elastic positioning member 2 in the annular guide 52. By providing a smooth curved surface 561 to the outlet opening 55 at the lower surface of the slot 56 adjacent to the outlet 55, the outlet opening 55 is enlarged in space, thereby reducing the bending at the outlet 55 and the rotation base. The friction between the transmission line 7 around the seat 5 and the edge of the spacer 53 further reduces the risk of breakage of the core of the transmission line 7, improves product life and reliability, and at the same time, moves outward through the side of the support 54 of the rotary base 5 to support the transmission line. 7 causes the transmission line 7 to be convex, and the projection of the transmission line 7 which is bent in conjunction with the outlet opening 55 is such that the transmission line 7 wound around the periphery of the rotary base 5 is smooth and more beautiful.

When the reel assembly 100 of the present invention is in operation, the two ends of the transmission line 7 are pulled outward to rotate the rotary base 5, and at the same time, the vortex spring 6 is compressed to release the transmission line 7, until the outlet line completes the positioning post 21 The locking position of the annular guide 52 is fixed, so that the user can smoothly pull out the transmission line 7. When the reel assembly 100 of the present invention receives the transmission line 7, it is only necessary to disengage the positioning post 21 from the stuck position of the annular guide 52, and pull the transmission line 7 back to the outer compartment of the rotary base 5 by the restoring force of the swirl spring 6. Therefore, the user can smoothly complete the transmission line 7 storage.
