Please refer to FIG. 4 and FIG. 5 , and refer to FIG. 2 and FIG. 3 together. FIG. 4 is a cross-sectional view of the retracting line structure 100 of FIG. 1 along the cutting line 4-4. The figure shows another cross-sectional view of the retractable wire structure 100 of FIG. The cap 500 of the retractable wire structure 100 has a central axis I, and the cap 500 can be pulled up along the central axis I and drive the tilting unit 400 to move upward. Therefore, the tilting unit 400 has a first position relative to the outer casing 200. And the second position. When the swaying unit 400 is in the first position, as shown in FIG. 4, the snap member 240 is engaged with the first joint portion 431; when the screw cap 500 is pulled up, as shown in FIG. 5, at this time 掣When the movable unit 400 is in the second position, the latching member 240 is engaged with the second joint portion 432.

When the tilting unit 400 is in the first position and the latching member 240 is engaged with the first joint portion 431, the convex arm 422 interferes with the ring gear 250 (see FIG. 2). Since the convex arm 422 has some elasticity, when the screw cap 500 drives the tilting unit 400 to rotate in the tightening direction A2, the convex arm 422 is continuously pressed away from the ring tooth 250. In other words, the convex arm 422 cannot prevent the screw cap 500 from rotating relative to the outer casing 200 in the fastening direction A2. Therefore, the screw cap 500 can drive the tilting unit 400 and the bobbin 300 to rotate in the fastening direction A2, and the wire body is wound around the bobbin 300. . On the other hand, when the cap 500 is to be rotated in the releasing direction A1, the cam 422 engages the ring tooth 250 so that the cap 500 cannot be rotated relative to the outer casing 200 in the releasing direction A1, and the wire body cannot be pulled out at this time. Therefore, in Fig. 4, the retractable wire structure 100 can only take up the line. In addition, due to the interference relationship between the convex arm 422 and the ring tooth 250, the speed is slow when the wire is taken up, and the user puts the hand to rotate without the screw cap. At 500 o'clock, the line body will not be loosened automatically, so the fine adjustment of the line body tightness can be performed.

As shown in FIG. 5, when the tilting unit 400 is in the second position and the latching member 240 is engaged with the second engaging portion 432, the protruding arm 422 is separated from the outer casing 200 and separated from the ring tooth 250, so the screw cap 500 can be opposite to the outer casing. 200 rotates in the loose direction A1 or the tightening direction A2. In addition, the external teeth 310 and the internal teeth 423 (see FIG. 3) remain engaged, so that the screw cap 500 and the spool 300 can still interlock with each other. When the wire body is pulled out, the screw cap 500 will rotate together, at this time, The screw cap 500 can be rotated in different directions to retract the wire body. When the wire body length reaches the expected length, the screw cap 500 is pressed down to switch the tilting unit 400 to the first position to fasten the wire body.

In this embodiment, the first joint portion 431 is an outer ring groove disposed on the base post 433, the second joint portion 432 is another outer ring groove disposed on the base post 433, and the snap member 240 includes a convex portion. The portion 241 corresponds to any outer ring groove. In other embodiments, the latching member may include a recess, and the first joint portion and the second joint portion may be a convex ring disposed on the base post, so that the convex ring and the recess portion are engaged with each other, and the disclosure is not disclosed above. limit.

In addition, as can be seen from FIG. 4, the height d2 of the outer teeth 310 of the present embodiment parallel to the central axis I is greater than the height d1 of the parallel central axis I of the convex arms 422, and thus the tilting unit 400 is located at the first position or the second. In position, the outer teeth 310 and the inner teeth 423 are engaged, and the screw cap 500 is moved in the first position and the second position together with the bobbin 300.

Please refer to FIG. 6 , FIG. 7 and FIG. 8 , wherein FIG. 6 is a perspective view of a retractable wire structure 110 according to another embodiment of the present invention, and FIG. 7 is a view showing the retractable wire structure 110 of FIG. 6 . One-dimensional explosion In an attempt, FIG. 8 is a schematic view showing another perspective body explosion of the retractable wire structure 110 of FIG.

In addition, the structures of the outer casing 200a, the bobbin 300a, and the moving member 430a are similar to those of the first to fifth embodiments, and are not described herein again. However, in the present embodiment, the moving member is particularly illustrated. The recess 434a of the 430a is engaged with the hole portion 425 to interlock the moving member 430a with the latch member 420a.

Please refer to FIG. 9 and FIG. 10, and refer to FIG. 7 and FIG. 8 together. FIG. 9 is a cross-sectional view of the retracting line structure 110 of FIG. 6 along the cutting line 9-9. The figure shows another cross-sectional view of the retractable wire structure 110 of FIG. In the present embodiment, the screw cap 500a can also be pulled up along the central axis I2. The axial movement of the screw cap 500 can cause the tilting unit 400a to have a first position and a second position relative to the outer casing 200a.

As shown in Fig. 9, when the screw cap 500a is not pulled up, the tilting unit 400a is in the first position, the convex arm 422a is engaged with the ring tooth 250a (see Fig. 7), and because the convex arm 422a can be fastened The direction A2 is disengaged from the ring gear 250a, and the rotating screw cap 500a is connected to the bobbin 300a to rotate in the tightening direction A2. The wire body wraps around the bobbin 300a, and the convex arm 422a cannot be disengaged from the ring tooth 250a in the releasing direction A1, thereby preventing the wire body from coming loose and achieving the purpose of wire take-up, fine adjustment tightness, and fastening.

As shown in FIG. 10, when the screw cap 500a is pulled up, the tilting unit 400a is in the second position and drives the convex arm 422a away from the outer casing 200a, so that the convex arm 422a is separated from the ring tooth 250a, and the inner tooth 423a is still outside. The tooth 310a (see Fig. 7) is engaged. At this time, the wire body can be pulled out to rotate the bobbin 300a to rotate the cap 500a in the releasing direction A1, so that the wire is in the pay-off state, and the cap 500a can be directly tightened. The A2 rotates quickly to retract the line.

In addition, as shown in FIG. 9, the height d2 of the outer teeth 310a parallel to the central axis I2 in this embodiment is greater than the height d1 of the parallel arm axis 422a parallel to the central axis I2, and thus the tilting unit 400a is located at the first position or the second position. The outer teeth 310a and the inner teeth 423a are engaged, and the screw cap 500a is moved in the first position and the second position together with the bobbin 300a.

As can be seen from the above embodiments, the present invention has the following advantages.
