The end of the movable plate 300 close to the positioning protrusion 310 is provided with a first protruding tooth 320 and a second protruding tooth 330 on both sides of the swivel 400 respectively.

[0050] The limiting plate 500 is connected to the rear of the rotating plate 210 at intervals, and a winding space is formed between the limiting plate 500 and the rotating plate 210;

[0051] The spiral spring 600 is disposed at one end of the limiting plate 500 facing away from the rotating plate 210 , and the spiral spring 600 is connected to the second hinge portion 240 ;

[0052] The data cable 700 includes a first end 710, a cable 720 and a second end 730 connected in sequence. The first end 710 is located at the first outlet 140, the second end 730 is located at the second outlet 150, and the cable 720 is located in the winding space.

In particular, the second terminal 730 is limited to 90° rotation by the second outlet 150 and / or the receiving groove 151. At this time, an opening 530 can be opened on the limiting plate, and the cable 720 connected to the first terminal 710 can be connected to the first terminal 710 from the middle mounting missing ring 250 and the opening 530 on the limiting plate. In particular, a receiving groove 151 is also provided at the first outlet 140 to accommodate the first terminal 710.

[0055] Please refer to Figure 2-Figure 5 , further comprising a damping disc 800, the limiting disc 500 rotates with the rotating disc 210, the damping disc 800 is arranged at one end of the limiting disc 500 facing away from the rotating disc 210, and a plurality of damping structures are arranged between the limiting disc 500 and the damping disc 800.

[0056] Please refer to Figure 2-Figure 5 The damping structure includes a spring sheet, and a plurality of spring sheets are arranged symmetrically or in a circular array around the second hinge portion 240. In particular, a spring sheet mounting seat is arranged on the limiting plate 500, and the spring sheet is fixed in the spring sheet mounting seat and abuts against the damping plate 800.

[0057] Please refer to Figure 2-Figure 5 The damping structure includes a spring sheet group, each spring sheet group is provided with a plurality of spring sheets in the radial direction, and the plurality of spring sheet groups are symmetrically or annularly arranged around the second hinge portion 240. Simply, each spring sheet group includes a spring sheet mounting seat, the spring sheet mounting seat has a plurality of spring sheet mounting grooves, the spring sheets are fixed in the spring sheet mounting grooves to form a spring sheet group, and the spring sheet group abuts against the damping disc 800.

[0058] In particular, a damping ring corresponding to the path of the spring is provided on the damping disc 800, and the damping ring can be made of a metal patch or an alloy patch to improve the wear resistance of the damping ring.

[0059] Please refer to Fig.12 The rotating tooth 410 includes a first inclined surface 411, a second inclined surface 412 and a third inclined surface 413 connected to each other. The second inclined surface 412 is a surface away from the first hinge portion 220. The angle between the first inclined surface 411 and the second inclined surface 412 is an obtuse angle, and the angle between the second inclined surface 412 and the third inclined surface 413 is an acute angle. In particular, the extension of the first inclined surface 411 and the extension of the second inclined surface 412 intersect at the rotation center of the rotating tooth 410. The second inclined surface 412 is provided so that the rotating tooth 410 has only one direction of limit, and the other direction forms a transition surface through the second inclined surface 412, so that the cable 720 has a sense of rhythm when stretched and is fast when retracted.

[0060] Please refer to Figure 8 The first protruding tooth 320 includes a fourth inclined surface 321 and a fifth inclined surface 322 connected to each other. The included angle between the fourth inclined surface 321 and the fifth inclined surface 322 is equal to the included angle between the second inclined surface 412 and the third inclined surface 413 and is less than 90°.

[0061] Please refer to Figure 8 The front end of the second protruding tooth 330 is an arc surface 331, and the two parts are the sixth inclined surface 332 and the seventh inclined surface 333. The angle between the sixth inclined surface 332 and the seventh inclined surface 333 is smaller than the angle between the second inclined surface 412 and the third inclined surface 413. The different shapes of the first protruding tooth 320 and the second protruding tooth 330 enable the cable 720 to be fixed, but smoothly retracted. The sixth inclined surface 332 and the seventh inclined surface 333 are particularly symmetrically arranged.

[0062] Particularly, the included angle between the first bevel 411 and the second bevel 412 is 100°-130°, the included angle between the second bevel 412 and the third bevel 413 is 30°-50°, the included angle between the fourth bevel 321 and the fifth bevel 322 is 50°-70°, and the included angle between the sixth bevel 332 and the seventh bevel 333 is 30°-40°.

[0063] Please refer to Fig.12 The root of the tooth groove is also provided with a stepped protrusion 420, and the stepped protrusion 420 and the two adjacent rotating teeth 410 form a stepped inner groove 421. The stepped protrusion 420 can not only improve the strength of the rotating teeth 410, but also when the cable 720 is pulled strongly and inverted to deform, the stepped inner groove 421 can lock the first protruding tooth 320 or the second protruding tooth 330. In particular, the stepped protrusion 420 is flush with the second inclined surface 412.

[0064] Preferably, the width of the positioning groove 231 gradually increases radially outward. In particular, the width of the positioning protrusion 310 gradually decreases in the direction toward the positioning groove 231. Generally, there is a gap between the positioning protrusion 310 and the bottom and both sides of the positioning groove 231, so that the positioning protrusion 310 can be separated from the positioning groove 231 when subjected to a sufficient force.

[0065] Particularly, a convex body 340 is disposed on a surface of the movable plate 300 facing the rotating disk 210 , so that a gap exists between the main body of the movable plate 300 and the rotating disk 210 .

[0066] In particular, the middle portion of the cable 720 is installed in the mounting ring 250, and the cable 720 extending from the notch of the mounting ring 250 overlaps and is wound in the same direction, so that the first end 710 and the second end 730 can be retracted.

[0067] Generally, the front shell 110 and the rear shell 120 are connected by snap-fit, and can also be connected by screws as needed.

[0068] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0069] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0070] In summary, the utility model provides a retractable data cable. When the data cable is pulled out, the positioning assembly cooperates with the rotating mounting plate, and stops and loosens at the same time. When the cable is pulled, the movable plate rotates and deflects, and the positioning protrusion disengages from the positioning groove. The cable moves smoothly, and the first convex tooth is engaged in the tooth groove to prevent excessive displacement. After pulling a sufficient distance, it is retracted a short distance, so that the positioning protrusion is engaged in the positioning groove, and the cable is fixed. When the data cable needs to be retracted, the cable is quickly pulled, the positioning protrusion is disengaged from the positioning groove again, and the cable is recovered under the action of the spiral spring, the movable plate deflects to the other side, and the second convex tooth is engaged in the tooth groove to prevent excessive displacement.
