For this design, the winding bracket 2 is blocked at the first angle position by the at least one limiting mechanism, so that the winding bracket 2 is relatively stably maintained at the first angle position during winding, thereby facilitating the winding of the cable 50 relative to the winding bracket 2; the winding bracket 2 overcomes the blocking of the at least one limiting mechanism under the push of a person's hand and rotates along the rotation direction to disengage from the first angle position, so that the winding bracket 2 can be pushed away from the first angle position, facilitating the subsequent removal of the wound cable 50 from the winding bracket 2 relatively as a whole, so as to be released for use; in summary, the user experience of this design is better. The at least one limiting mechanism is used to block the winding bracket 2 at the first angle position, and further, the at least one limiting mechanism can be used to block the winding bracket 2 at the first angle position during the process of the cable 50 being wound around the winding device.

[0058] In this embodiment, the limiting mechanism is a limit pin that can be retracted and moved. The winding bracket 2 can be pushed by a person's hand to rotate along the rotation direction and push the at least one limit mechanism to retract, thereby overcoming the obstruction of the at least one limit mechanism, and enabling the winding bracket 2 to slide through the at least one limit mechanism and leave the first angle position. In other embodiments, the limiting mechanism can also be a fixed limiting protrusion. The winding bracket 2 can be pushed by a person's hand and slide through the limiting protrusion under the condition of interference friction with the limiting protrusion to overcome the obstruction of the at least one limit mechanism, thereby leaving the first angle position.

[0059] The winding device also includes a first pier 3, and the at least one limiting mechanism is installed on the first pier 3. The winding bracket 2 can be rotated along the rotation direction under the push of a person's hand to push the at least one limiting mechanism to retract into the first pier 3, so that the winding bracket 2 overcomes the obstruction of the at least one limiting mechanism and leaves the first angle position. The winding bracket 2 can push the at least one limiting mechanism to retract into the first pier 3 and slide over the at least one limiting mechanism during the rotation process from the first angle position along the rotation direction.

[0060] The winding bracket 2 is rotatably connected to the first pier 3. The winding bracket 2 includes a first rotating shaft portion 20 and a second rotating shaft portion 21. The first rotating shaft portion 20 and the second rotating shaft portion 21 extend toward each other. The first rotating shaft portion 20 and the second rotating shaft portion 21 are used to form the rotating shaft of the winding bracket 2. The first pier 3 includes a first rotating shaft hole 30 corresponding to the first rotating shaft portion 20 and a second rotating shaft hole 31 corresponding to the second rotating shaft portion 21. The first rotating shaft portion 20 is inserted into the first rotating shaft hole 30, and the second rotating shaft portion 21 is inserted into the second rotating shaft hole 31. The first rotating shaft hole 30 and the second rotating shaft hole 31 are located on opposite sides of the first pier 3. Such a design promotes a simple and effective rotating connection and cooperation between the winding bracket 2 and the first pier 3, and the first pier 3 can also provide a certain degree of protection or support for the winding bracket 2.

[0061] The winding device also includes a handle 10, which is for a person to hold, and the handle 10 is connected to the first pier 3. The rotation axis of the winding bracket 2 is perpendicular to the handle 10. The winding bracket 2 forms a non-closed loop frame, and the winding bracket 2 can be rotated to a state where it is framed on the first pier 3. With such a design, the structure of the winding bracket 2 is simple and practical, and can be well matched with the first pier 3.

[0062] The rotation axis of the winding bracket 2 is perpendicular to the first pier 3. The winding bracket 2 forms a non-closed loop frame, and the winding bracket 2 can be rotated to a state where it is framed on the first pier 3. Such a design promotes a better match between the winding bracket 2 and the first pier 3. When the winding bracket 2 rotates, it rotates around its rotation axis.

[0063] The winding device also includes the at least one installation opening corresponding to the at least one limiting mechanism, the limiting pin is installed on the corresponding installation opening, and the limiting pin can perform telescopic movement along the corresponding installation opening.

[0064] The winding device also includes at least one elastic element 11, and the limit pin includes at least one folded edge 42, which is located at the periphery of the inner end of the limit pin, and the at least one folded edge 42 is bent and connected to the inner end of the limit pin. Under the push of the elastic element 11 on the limit pin, the at least one folded edge 42 can be stopped at the inner end of the installation opening to prevent the limit pin from detaching from the installation opening outward.

[0065] The at least one limiting mechanism includes a first limiting pin 40 and a second limiting pin 41. The at least one mounting opening includes a first mounting opening 32 and a corresponding second mounting opening 33. The first limiting pin 40 is correspondingly mounted on the first mounting opening 32, and the second limiting pin 41 is correspondingly mounted on the second mounting opening 33. Under the push of the winding bracket 2, the first limiting pin 40 and the second limiting pin 41 can move along the first mounting opening 32 toward the direction close to the second mounting opening 33, and the second limiting pin 41 can move along the second mounting opening 33 toward the direction close to the first mounting opening 32. With such a design, the winding bracket 2 can evenly push the first limiting pin 40 and the second limiting pin 41, so that the winding bracket 2 can slide through the at least one limiting mechanism more smoothly and leave the first angle position.

[0066] Under the push of the winding bracket 2, the first limit pin 40 and the second limit pin 41 move along the first mounting opening 32 toward the second mounting opening 33 and the second limit pin 41 moves along the second mounting opening 33 toward the first mounting opening 32, so that the winding bracket 2 can slide through the at least one limit mechanism and leave the first angle position.

[0067] The first installation opening 32 and the second installation opening 33 are opened in the first pier 3 and are located on opposite sides of the first pier 3. The first installation opening 32 and the second installation opening 33 respectively pass through the interior of the first pier 3 and the exterior of the first pier 3. The first limit pin 40 and the second limit pin 41 are exposed on opposite sides of the first pier 3. The winding bracket 2 can push the first limit pin 40 and the second limit pin 41 to retract toward the first pier 3 during the rotation process from the first angle position along the rotation direction, so that the winding bracket 2 overcomes the obstruction of the first limit pin 40 and the second limit pin 41 and slides through the first limit pin 40 and the second limit pin 41, thereby leaving the first angle position.

[0068] The winding bracket 2 also includes a first extension arm section 22 and a second extension arm section 23. The first limit pin 40 corresponds to the first extension arm section 22, and the second limit pin 41 corresponds to the second extension arm section 23. As the winding bracket 2 rotates from the first angle position along the rotation direction, the first extension arm section 22 pushes the first limit pin 40 to retract and the second extension arm section 23 pushes the second limit pin 41 to retract, so that the first extension arm and the first extension arm can overcome the obstruction of the corresponding first limit pin 40 and the second limit pin 41, and slide over the first limit pin 40 and the second limit pin 41, so that the winding bracket 2 can leave the first angle position. For the first extension arm section 22, as the winding bracket 2 rotates from the first angle position along the rotation direction, the first extension arm section 22 pushes the corresponding limit pin to retract and slides over the corresponding limit pin.

[0069] One of the installation opening and the stop pin is provided with a guide groove 34, and the other of the installation opening and the stop pin is provided with a slider 43 corresponding to the guide groove 34. The slider 43 is at least partially embedded in the guide groove 34. With the telescopic movement of the stop pin relative to the corresponding installation opening, the slider 43 slides along the guide groove 34. With such a design, the guide groove 34 and the slider 43 can be used to assist in guiding the telescopic movement of the stop pin relative to the corresponding installation opening.

[0070] The at least one elastic element 11 is used to provide an elastic thrust force to the at least one limiting mechanism so that the at least one limiting mechanism can elastically extend and retract. The at least one elastic element 11 is in a compressed state under the thrust of the corresponding at least one limiting mechanism. The first limiting pin 40 and the second limiting pin 41 can move toward each other under the thrust of the winding bracket 2 and compress the at least one elastic element 11 toward each other.

[0071] In this embodiment, the at least one elastic element 11 is a single compression spring, which is shared by the first limit pin 40 and the second limit pin 41. One end of the compression spring pushes the first limit pin 40 to one side and the other end of the compression spring pushes the second limit pin 41 to the other side. The first limit pin 40 and the second limit pin 41 always maintain the compression of the compression spring, thereby preventing the first limit pin 40 and the second limit pin 41 from being loose. The elastic thrust force provided by the single compression spring to the first limit pin 40 and the second limit pin 41 is basically eliminated except for the compression spring between the first limit pin 40 and the second limit pin 41. The structural design is simple, and the first limit pin 40 and the second limit pin 41 compress the single compression spring to produce a double compression effect on the compression spring.

[0072] The first limit pin 40 includes a first boss 400, the second limit pin 41 includes a second boss 410, one end of the compression spring is sleeved on the first boss 400, and the other end of the compression spring is sleeved on the second boss 410, so that the compression spring is simply matched with the first limit pin 40 and the second limit pin 41 on both sides. The first limit pin 40 and the second limit pin 41 can move toward each other under the push of the winding bracket 2, so that the winding bracket 2 can overcome the obstruction of the first limit pin 40 and the second limit pin 41 and leave the first angle position; the first limit pin 40 and the second limit pin 41 can move toward each other under the push of the winding bracket 2, so that the winding bracket 2 can slide over the first limit pin 40 and the second limit pin 41 and leave the first angle position.

[0073] When the winding bracket 2 rotates to the second angle position along the rotation direction, the winding bracket 2 abuts against the handle 10 and is blocked by the handle 10, so that the winding bracket 2 stops rotating at the second angle position. The winding bracket 2 forms a non-closed loop frame, and the winding bracket 2 can rotate to a state where it is framed on the first pier 3. With this design, the structure of the winding bracket 2 is simple and practical, and can be well matched with the first pier 3.

[0074] The wire winding bracket 2 further includes a wire blocking portion 24, which is used to block the cable 50 wound on the winding device to prevent the cable 50 from detaching from the wire winding bracket 2. In short, the wire blocking portion 24 is used to prevent the wound cable 50 from slipping off the wire winding bracket 2. The wire blocking portion 24 constitutes a hook portion of the wire winding bracket 2 that prevents the cable 50 from slipping off. When the wire winding bracket 2 rotates to the second angle position along the rotation direction, the wire blocking portion 24 straddles the handle 10 and the wire blocking portion 24 is in contact with the handle 10 and is blocked by the handle 10, so that the wire winding bracket 2 stops rotating at the second angle position. In this embodiment, the wire blocking portion 24 is bent and extended into a U shape.

[0075] One end of the handle 10 is connected to the first pier 3. When the winding bracket 2 is at the second angle position, the wire blocking portion 24 straddles and abuts against the end of the handle 10, thereby facilitating improving the position stability of the winding bracket 2 at the second angle position.

[0076] The rotation axis of the winding bracket 2 extends left and right, the first extension arm section 22 and the second extension arm section 23 are located on the left and right sides of the winding bracket 2, the wire blocking portion 24 connects the first extension arm section 22 and the second extension arm section 23, the grip 10 extends forward from the first pier 3, one end of the grip 10 is the rear end of the grip 10, and when the winding bracket 2 is at the second angle position, the wire blocking portion 24 straddles the rear end of the grip 10 and is connected to the top of the rear end of the grip 10. Such a design promotes the effective matching of the wire blocking portion 24 and the grip 10 when the winding bracket 2 is at the second angle position, which is conducive to improving the position stability of the winding bracket 2 when it is at the second angle position.

[0077] The first extension arm section 22 and the second extension arm section 23 are located on the left and right sides of the first pier 3, and the wire blocking section 24 is connected between the first extension arm section 22 and the second extension arm section 23. When the winding bracket 2 is at the first angle position, the wire blocking section 24 is located at the rear side of the first pier 3; when the winding bracket 2 is at the second angle position, the wire blocking section 24 is located at the front side of the first pier 3; during the process of the winding bracket 2 rotating from the first angle position to the second angle position along the rotation direction, the wire blocking section 24 rotates from the rear side of the first pier 3 to the front side of the first pier 3 through the top of the first pier 3. Such a design is conducive to the wire blocking section 24 being able to avoid the first pier 3 during the rotation process, and is also conducive to ensuring that the wire blocking section 24 of the winding bracket 2 at the second angle position is moved away enough, so that the wire blocking section 24 can more fully avoid / not block the wound cable 50 when the wound cable 50 is subsequently removed.

[0078] The rear end of the handle 10 is connected to the first pier 3. When the winding bracket 2 is at the second angle position, the wire blocking portion 24 is located at the rear side of the first extension arm section 22 and the second extension arm section 23, and the handle 10 is located at the front side of the first extension arm section 22 and the second extension arm section 23. When the winding bracket 2 is at the second angle position, the wire blocking portion 24 straddles the rear end of the handle 10. Such a design is conducive to the position stability of the winding bracket 2 at the second angle position, and is conducive to ensuring that the wire blocking portion 24 of the winding bracket 2 at the second angle position can not block the removal of the wound cable 50.

[0079] The winding bracket 2 of this embodiment is limited to rotating between the second angle position and a third angle position, so that the winding bracket 2 of this embodiment cannot rotate 360 ​​degrees; the winding bracket 2 can rotate from the second angle position to the third angle position against the rotation direction and can rotate from the third angle position to the second angle position along the rotation direction; the winding bracket 2 includes at least one support section, and when the winding bracket 2 rotates to the third angle position against the rotation direction, the at least one support section is stopped so that the winding bracket 2 stops rotating at the third angle position. In this embodiment, the first angle position and the third angle position of the winding bracket 2 are very close and almost overlap, and the angle difference between the first angle position and the third angle position is between 0 degrees and 10 degrees. Therefore, it is not easy to distinguish whether the winding bracket 2 is in the first angle position or in the third angle position; the winding bracket 2 can rotate to the third angle position by rotating a small angle from the first angle position against the rotation direction. For this embodiment, the cable 50 can also be wound when the winding bracket 2 is at the third angle position. Specifically, the cable 50 is wound when the winding bracket 2 is at the third angle position. During the winding process, the cable 50 pushes the winding bracket 2 to rotate from the third angle position to the first angle position. At this time, the winding bracket 2 is blocked by the at least one limiting mechanism and can stay at the first angle position. During the rotation of the winding bracket 2 between the second angle position and the third angle position, the winding bracket 2 slides over the at least one limiting mechanism, which also causes sliding friction between the winding bracket 2 and the at least one limiting mechanism; the angle difference between the second angle position and the third angle position is between 35 degrees and 90 degrees.

[0080] The at least one support section includes a first support section 25 and a second support section 26, and the winding device is also provided with a first support portion 120 and a second support portion 121. When the winding bracket 2 rotates to a third angle position opposite to the rotation direction, the first support section 25 is supported on the first support portion 120 and is stopped by the first support portion 120, and the second support section 26 is supported on the second support portion 121 and is stopped by the second support portion 121, so that the winding bracket 2 is stopped at the third angle position more stably and evenly.

The winding bracket 2 is designed in this way so that the winding bracket 2 can be simple and effective in taking into account both the support to stop rotation and the limitation of the cable 50 during winding; when viewed from the side, the first support section 25, the second support section 26, the first extension arm section 22, the second extension arm section 23, and the wire blocking portion 24 form a Z shape as a whole. The first plane is introduced in the present application to facilitate the description of the relative position relationship of each technical feature. The first plane is defined based on the winding bracket 2. The virtual plane intersecting with the opposite ends of the first extension arm segment 22 is equivalent to the virtual plane where the opposite ends of the first extension arm segment 22 are located.

[0082] The first support section 25 is connected between the first extension arm section 22 and the first shaft section 20, and the second support section 26 is connected between the second extension arm section 23 and the second shaft section 21. The first shaft section 20 is bent and extended from one end of the first support section 25 away from the first extension arm section 22, and the second shaft section 21 is bent and extended from one end of the second support section 26 away from the second extension arm section 23; the first shaft section 20 extends from one end of the first support section 25 away from the first extension arm section 22 to the side where the second support section 26 is located, and the second shaft section 21 extends from one end of the second support section 26 away from the second extension arm section 23 to the side where the first support section 25 is located. Such a design makes the structure of the winding bracket 2 simple and practical.

[0083] The winding bracket 2 is formed by bending a steel wire, the rotation axis of the winding bracket 2 is perpendicular to the first support section 25 and the first extension arm section 22, the first support section 25 is perpendicular to the first extension arm section 22, the first extension arm section 22 is parallel to the second extension arm section 23, and the first support section 25 is parallel to the second support section 26. Such a design promotes the structure of the winding bracket 2 to be simple and stable, and facilitates the first support section 25 and the second support section 26 to obtain balanced support.

When the winding bracket 2 is at the second angle position, the winding bracket 2 is framed on the first pier 3 and / or the handle 10. The second pier 13 is provided with a winding groove 130, which is located on the side of the second pier 13 facing away from the first pier 3, and the wound cable 50 is limited by the winding groove 130 and does not leave the second pier 13.

[0086] The limiting mechanism can be a limiting pin that can be retracted and moved. The winding bracket 2 can be rotated along the rotation direction under the push of a person's hand and slide through the at least one limiting mechanism to leave the first angle position. The winding bracket 2 can be formed by bending a metal wire, so that the winding bracket 2 is easy to manufacture. Further, the winding bracket 2 can be formed by bending a steel wire, so that the winding bracket 2 is easy to manufacture and not easy to damage.

[0087] When winding the cable 50, the winding bracket 2 can be first rotated to the first angle position, and then the cable 50 can be wound around the winding bracket 2, the first pier 3 and the second pier 13 to complete the winding of the cable 50; when the wound cable 50 needs to be removed, the winding bracket 2 can be first rotated to the second angle position, so that the wound cable 50 is no longer blocked by the wire blocking portion 24, and then the wound cable 50 is first taken away from the winding bracket 2, and then the cable 50 is taken away from the second pier 13, and the cable 50 can be released for use.
