In order to have a further understanding and understanding of the features of the application and the achieved effects, only the embodiments and detailed descriptions are provided, as follows: Please refer to Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5, which are the perspective view, exploded view, schematic diagram of the wire reel, the combination diagram of the wire reel, the resistance adjustment component and the linkage mechanism, and the combination perspective view of the resistance adjustment component and the linkage mechanism of the first embodiment of the application; Adjust the component 11 and the linkage mechanism 12, the cord reel 10 includes a magnetic action part 101, the magnetic action part 101 is arranged on the surface of the cord reel 10, in this embodiment, the cord reel 10 has a first surface 10a and a second surface 10b, the first surface 10a is opposite to the second surface 10b, and the magnetic action part 101 is arranged on the second surface 10b of the cord reel 10. The resistance adjustment assembly 11 is disposed on one side of the cord reel 10 . The resistance adjustment assembly 11 includes a first magnetic body 111 , the first magnetic body 111 is disposed on the surface of the resistance adjustment assembly 11 facing the magnetic action part 101 , and the first magnetic body 111 is disposed corresponding to the magnetic action part 101 . In this embodiment, the resistance adjustment assembly 11 is arranged on the side of the cord reel 10 having the magnetic action part 101, that is, the cord reel The second surface 10b of the reel 10 faces the resistance adjustment assembly 11 , so that the magnetic action portion 101 on the second surface 10b of the cord reel 10 corresponds to the first magnetic body 111 of the resistance adjustment assembly 11 . The linkage mechanism 12 is respectively connected to the cord reel 10 and the resistance adjustment assembly 11 , so the linkage mechanism 12 is also located below the second surface 10 b of the cord reel 10 to be connected to the cord reel 10 and the resistance adjustment assembly 11 .

Please refer to Fig. 1, Fig. 6, Fig. 7, Fig. 8 and Fig. 9 together. Fig. 6 and Fig. 8 are diagrams showing the state of use of the wire reel device according to the first embodiment of the present application. Fig. 7 and Fig. 9 are respectively an enlarged view of area A in Fig. 6 and an enlarged view of area B in Fig. 8; 10, or the wire 103 is tightened so that the wire 103 is recovered into the wire reel 10. When the cord reel 10 rotates, the cord reel 10 drives the linkage mechanism 12, and the linkage mechanism 12 drives the resistance adjustment assembly 11 to move relative to the magnetic action part 101. In this embodiment, the resistance adjustment assembly 11 moves along a direction perpendicular to the second surface 10b of the cord reel 10. The resistance adjustment assembly 11 adjusts the distance D between the first magnetic body 111 and the magnetic action part 101 according to the rotation direction of the cord reel 10 , so as to adjust the force that the first magnetic body 111 acts on the magnetic action part 101 .

The rotation direction of the wire reel 10 includes a first direction and a second direction. The first direction refers to the rotation direction of the wire reel 10 when the wire 103 in the wire reel 10 is pulled out. On the contrary, the second direction refers to the rotation direction of the wire reel 10 when the wire 103 of the wire reel 10 is recovered. When the rotation direction of the cord reel 10 is the first direction, the initial position of the resistance adjustment assembly 11 is away from the magnetic action part 101 of the cord reel 10 (as shown in FIGS. 6 and 7 ). As the cord reel 10 continues to rotate along the first direction, the linkage mechanism 12 drives the resistance adjustment assembly 11 to move in a direction close to the magnetic action part 101 of the cord reel 10 (as shown in FIGS. 8 and 9 ). and magnetic interaction The distance D between 101 gradually decreases, and the force exerted by the first magnetic body 111 on the magnetic action part 101 gradually increases, so as to gradually reduce the rotation speed.

When the rotation direction of the cord reel 10 is the second direction, the initial position of the resistance adjustment assembly 11 is close to the magnetic action part 101 of the cord reel 10 (as shown in FIGS. 8 and 9 ). As the cord reel 10 continues to rotate along the second direction, the linkage mechanism 12 drives the resistance adjustment assembly 11 to move away from the magnetic action part 101 of the cord reel 10 (as shown in FIGS. 6 and 7 ). The distance D from the magnetic action part 101 gradually increases, and the force of the first magnetic body 111 acting on the magnetic action part 101 gradually decreases. Because there is a scroll spring in the cord reel 10, the scroll spring makes the torque of the cord reel 10 different when the wire 103 is unwound and the wire 103 is tightened, resulting in a too fast rotation speed of the cord reel 10 when the wire 103 is recovered. Therefore, the cord reel 1 of this embodiment uses the resistance adjustment component 11 to make the torque of the wire 103 unwind and the wire 103 tight. The adjustment assembly 11 is automatically adjusted according to the rotation state of the wire reel 10, wherein the rotation state of the wire reel 10 includes a rotation direction and a rotation speed. Different rotation directions of the wire reel 10 can control the movement direction of the resistance adjustment assembly 11, and the speed of rotation of the wire reel 10 can control the movement speed of the resistance adjustment assembly 11 toward or away from the magnetic action part 101.
