[0011] Preferably, a second circuit board is provided on the side of the turntable facing the first housing, and a first limiting hole and a second limiting hole are respectively provided on the second circuit board and the first housing; when the first housing closes the second housing, the rotating shaft passes through the rotating hole, the first limiting hole, the central shaft hole and the second limiting hole in sequence, and abuts against the hole wall of the second limiting hole, and the first circuit board contacts the second circuit board and conducts circuit.

[0012] Preferably, the telescopic cable storage device further includes a stop member, a toggle member, and a spring piece; the stop member and the toggle member are stacked and rotatably connected to the first housing; the turntable has a plurality of first locking slots around the second circuit board on one side of the second circuit board; the first locking slots engage with the stop member; and the spring piece engages with the edge of the inner surface of the first housing and abuts against the toggle member.

[0013] Preferably, a plurality of second slots are provided at intervals on the boundary of the second circuit board, and the second slots are connected to the first slots.

[0014] Preferably, the stop member has an arc-shaped protrusion on the side facing away from the first housing, and the arc-shaped protrusion abuts against the side of the turntable where the second circuit board is disposed.

[0015] Compared with the prior art, the telescopic cable storage device provided by this utility model has the following beneficial effects:

[0016] 1. A telescopic cable storage device provided in this embodiment of the present invention includes a first housing and a second housing. The first housing covers the second housing and forms a receiving space. A first circuit board and a winding structure with a cable wound inside are disposed in the receiving space. The first housing and the second housing are detachably connected. The first circuit board is located between the winding structure and the inner surface of the first housing and is detachably connected to the first housing. The first circuit board includes an input end. At least two through holes are provided on the first housing. The through holes are disposed along the edge of the side of the first housing facing away from the receiving space. The input end of the first circuit board is exposed through one of the through holes. By using a detachable first housing and a first circuit board, and by providing at least two through holes on the first housing to expose the input end of the first circuit board, at least two through holes with different orientations are reserved for the input end of the first circuit board, so as to meet the user's desire to install the first circuit board in the desired direction; it is also possible to remove the first housing and the first circuit board, and then reinstall the input end of the first circuit board from the currently aligned through hole to another through hole, thereby realizing the adjustment and change of the position of the input end of the first circuit board, so as to realize the change of the power connection direction of the input end, which is convenient to meet the user's power connection needs in different directions during use, and improves the flexibility of the direction adjustment of the input end of the telescopic cord storage device.

[0017] 2. In this embodiment of the invention, the first housing has three through holes, each pointing in a different direction; the three through holes are evenly spaced around the center of the first housing. By setting the three through holes evenly spaced and corresponding to different pointing directions, three through holes with different pointing directions can be provided for the input end of the first circuit board, thus providing three mounting positions for the input end of the first circuit board, which is more conducive to the user adjusting the exposed position of the input end according to the actual product being used.

[0018] 3. In this embodiment of the invention, the first housing has an opening on its side for the cable to pass through, and the through hole is positioned to avoid the direction of the opening. This achieves a misalignment between the opening for the exposed cable and the through hole, preventing the opening and the through hole from pointing in the same direction, thereby avoiding interference caused by the cable and the input end being connected to the device in the same direction.

[0019] 4. In this embodiment of the invention, the first circuit board has a central shaft hole, and three evenly distributed positioning holes are arranged around the central shaft hole. Three positioning posts are arranged on the inner surface of the first housing corresponding to the positioning holes. When the first housing is closed with the second housing, the positioning posts pass through the positioning holes. By setting three positioning posts corresponding to the three positioning holes, the first circuit board can be fixed in its current position after each installation, ensuring a stable electrical connection. Furthermore, the evenly distributed positioning holes prevent interference with the adjustment direction of the first circuit board during installation.

[0020] 5. The three positioning holes provided in this embodiment of the utility model are distributed in a triangular shape, thereby improving the stability and firmness of the first circuit board during each installation and fixing, and further ensuring the stable electrical connection of the first circuit board.

[0021] 6. In this embodiment of the present invention, a second circuit board is provided on the side of the turntable facing the first housing. The second circuit board and the first housing are respectively provided with a first limiting hole and a second limiting hole. When the first housing closes the second housing, the rotating shaft passes through the rotating hole, the first limiting hole, the central shaft hole and the second limiting hole in sequence, and abuts against the hole wall of the second limiting hole. Thus, the rotating shaft limits and fixes the second housing, the second circuit board, the first circuit board and the first housing, thereby improving the stability of the connection between the components and improving the stability of the contact between the first circuit board and the second circuit board and the circuit conduction.

[0022] 7. The telescopic cable storage device provided in this embodiment of the present invention further includes a stop member, a toggle member, and a spring piece; the stop member and the toggle member are stacked and rotatably connected to the first housing; one side of the turntable where the second circuit board is located has multiple first locking slots around the second circuit board; the first locking slots engage with the stop member; the spring piece engages with the edge of the inner surface of the first housing and abuts against the toggle member. By setting the stop member and the toggle member, when the cable is pulled out to a certain length, the user releases the data cable, and the stop member quickly enters the first locking slot under the action of the spring piece, effectively preventing the turntable from continuing to rotate, thereby ensuring that the cable remains in the current position and avoiding excessive extension or contraction of the cable due to inertia.

[0023] 8. In this embodiment of the invention, a plurality of second locking slots are spaced apart on the boundary of the second circuit board, and the second locking slots are correspondingly connected to the first locking slots. By correspondingly providing second locking slots on the second circuit board, it is possible to prevent the locking member from abutting against the second circuit board after being inserted into the first locking slot, thereby preventing the movement of the locking member from affecting the circuit conduction between the second circuit board and the first circuit board, and further ensuring the stability of the circuit conduction between the second circuit board and the first circuit board.

[0024] 9. In this embodiment of the invention, the stop member has an arc-shaped protrusion on the side facing away from the first housing, and the arc-shaped protrusion abuts against the side of the turntable where the second circuit board is mounted. By setting the arc-shaped protrusion to abut against the turntable, a line contact can be formed between the stop member and the surface of the turntable when the stop member rotates, reducing the resistance generated by friction between the two. At the same time, the arc-shaped protrusion can also generate a tangential guiding force during rotation, thereby improving the accuracy of the stop member's motion trajectory.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0043] Please see Figures 1-3The first embodiment of this utility model provides a telescopic cable storage device 1, including a first housing 11 and a second housing 12. The first housing 11 covers the second housing 12 to form a receiving space 13. A first circuit board 15 and a winding structure 14 are disposed in the receiving space 13. The first housing 11 and the second housing 12 are detachably connected. The first circuit board 15 is located between the winding structure 14 and the inner surface of the first housing 11, and is detachably connected to the first housing 11. The first circuit board 15 includes an input terminal 151. At least two through holes 111 are provided on the first housing 11. The through holes 111 are disposed along the edge of the side of the first housing 11 facing away from the receiving space 13. The input terminal 151 of the first circuit board 15 is exposed through one through hole 111.

[0044] Specifically, a snap-fit ​​structure 115 can be provided on the boundary of the first housing 11, and a snap-fit ​​hole 122 can be provided on the second housing 12. When the first housing 11 covers the second housing 12, the snap-fit ​​structure 115 snaps into the snap-fit ​​hole 122, thereby realizing the detachable connection between the first housing 11 and the second housing 12 by snapping, making the operation of closing and separating the first housing 11 and the second housing 12 simpler and more convenient.

[0045] Optionally, the positions of the snap-fit ​​structure 115 and the snap hole 122 can be interchanged. The snap-fit ​​structure 115 can be set on the boundary of the second housing 12, and the snap hole 122 can be set on the first housing 11, so that a stable connection can be achieved after the first housing 11 covers the second housing 12.

[0046] More specifically, after the first housing 11 covers the second housing 12, a receiving space 13 is formed, which is enclosed by the inner surfaces of the first housing 11 and the second housing 12. This receiving space 13 is used to accommodate the winding structure 14 and the first circuit board 15. A wire 143 is wound on the winding structure 14, and the winding structure 14 can rotate relative to the first housing 11 and the second housing 12, thereby allowing the wire 143 on the winding structure 14 to rotate out of the receiving space 13 or to rotate the wire 143 back into the receiving space 13.

[0047] It should be noted that the first circuit board 15 in this embodiment can be a first PCB circuit board. This first PCB circuit board is located between the winding structure 14 and the inner surface of the first housing 11. The clamping of the winding structure 14 and the first housing 11 enhances the stability of the first PCB circuit board after installation. Traditional retractable data cables have their wires directly soldered, which leads to solder joint breakage after repeated winding, affecting the lifespan of the cable. This embodiment uses a first PCB circuit board, where the solder joints are fixed, distributing stress across the entire board. This solves the physical damage problem caused by the rotational conduction of traditional retractable data cables, thus improving their lifespan. The first circuit board 15 includes an input terminal 151, which is used for electrical connection to an external device to achieve charging or data transmission. Therefore, the input terminal 151 needs to be exposed on the surface of the retractable cable storage device 1 for connection to external devices.

[0048] Specifically, at least two through holes 111 with different orientations can be provided on the edge of the side of the first housing 11 facing away from the receiving space 13. The orientation of the through holes 111 is the direction pointed to by the center line of the through hole 111 passing through the center of the first housing 11. The input terminal 151 of the first circuit board 15 can be exposed from one of the through holes 111.

[0049] Understandably, by providing a detachable first housing 11 and a first circuit board 15, and by providing at least two through holes 111 on the first housing 11 to expose the input terminal 151 of the first circuit board 15, at least two through holes 111 with different pointing directions are reserved for the input terminal 151 of the first circuit board 15. This allows users to install the input terminal 151 of the first circuit board 15 in the desired direction, thus meeting the personalized needs of different users. Furthermore, by disassembling the first housing 11 and the first circuit board 15, the input terminal 151 of the first circuit board 15 can be moved from one of the currently aligned through holes 111 to another through hole 111 after disassembly. This allows for adjustment and transformation of the position of the input terminal 151 of the first circuit board 15, thereby changing the power connection direction of the input terminal 151. This facilitates meeting the user's power connection needs in different directions during use and improves the flexibility of adjusting the direction of the input terminal 151 of the telescopic cable storage device 1.

[0050] Please see Figures 2-4 Furthermore, an opening 112 for the wire 143 to pass through is provided on the side of the first housing 11, and the through hole 111 is set to avoid the direction of the opening 112.

[0051] Understandably, the first housing 11 and / or the second housing 12 may be provided with an opening 112 through which the wire 143 on the winding structure 14 passes. This allows the through hole 111 to be set away from the pointing direction of the opening 112, thereby misaligning the opening 112 through which the wire 143 is exposed with the through hole 111. This avoids the opening 112 and the through hole 111 pointing in the same direction, thus preventing the wire 143 and the input terminal 151 from being connected to the same device in the same pointing direction and causing mutual interference.

[0052] Understandably, two through holes 111 with different orientations can be provided on the first housing 11, thereby providing two different mounting orientations for the input terminal 151 of the first circuit board 15. Alternatively, three or more through holes 111 with different orientations can be provided on the first housing 11, thereby providing three or three different mounting orientations for the input terminal 151 of the first circuit board 15. This embodiment does not impose any limitations on this, as long as the number of through holes 111 is at least two and they point in different directions.

[0053] Please see Figure 2 and Figure 4 In one optional embodiment, the first housing 11 has three through holes 111, the three through holes 111 pointing in different directions; the three through holes 111 are distributed at equal intervals around the center of the first housing 11.

[0054] Specifically, when the first housing 11 has three through holes 111, the three through holes 111 need to be misaligned with the opening 112 of the wire supply body 143 on the first housing 11 and / or the second housing 12, so as to avoid the direction of the three through holes 111 coinciding with the direction of the opening 112, which would cause mutual interference when connected.

[0055] Understandably, by setting three equally spaced through holes 111 corresponding to different pointing directions, three through holes 111 with different pointing directions can be provided for the input terminal 151 of the first circuit board 15, thus providing three mounting positions for the input terminal 151 of the first circuit board 15. This makes it easier for users to adjust the exposed position of the input terminal 151 according to the actual product being used. Furthermore, the three through holes 111 are equally spaced around the center of the first housing 11 and avoid the direction corresponding to the opening 112, which helps to achieve a uniform distribution of the three through holes 111 on the first housing 11, making the range of the pointing directions of the three through holes 111 wider.

[0056] Please see Figure 2 , Figure 4 and Figure 5Furthermore, a central shaft hole 153 is provided on the first circuit board 15, and three evenly distributed positioning holes 154 are provided around the central shaft hole 153. Three positioning posts 113 are provided on the inner surface of the first housing 11 corresponding to the positioning holes 154. When the first housing 11 covers the second housing 12, the positioning posts 113 are inserted into the positioning holes 154.

[0057] Specifically, the first circuit board 15 includes a conductive end 152 and an input end 151. Three positioning holes 154 can be set on the three through holes 111 corresponding to each other on the conductive end 152. That is, three positioning holes 154 are respectively set on the conductive end 152 in the three pointing directions or their extension directions corresponding to the three through holes 111. The three positioning holes 154 are evenly distributed, which can avoid affecting the adjustment direction each time the first circuit board 15 is installed and fixed. This ensures that no matter which through hole 111 the input end 151 of the first circuit board 15 is exposed, the three positioning posts 113 on the inner surface of the first housing 11 can be inserted into the three positioning holes 154 on the conductive end 152, thereby limiting and fixing the first circuit board 15 installed at the current through hole 111 position, so as to ensure the stable electrical connection of the first circuit board 15.

[0058] Please see Figure 5 Furthermore, the three positioning holes 154 are distributed in a triangular shape, which improves the stability and firmness of fixing the first circuit board 15 each time it is installed, and further ensures the stable electrical connection of the first circuit board 15.

[0059] Optionally, the three positioning holes 154 can be distributed in the shape of an acute triangle, preferably in the shape of an isosceles triangle or an equilateral triangle. The three positioning posts 113 on the first housing 11 correspond to the distribution of the three positioning holes 154, further ensuring that no matter which through hole 111 the input end 151 of the first circuit board 15 is exposed, it will be limited and fixed by the three positioning posts 113 passing through the three positioning holes 154.

[0060] Please see Figure 2 Furthermore, a rotating shaft 121 is provided at the center of the inner surface of the second housing 12. The winding structure 14 includes a turntable 141, a spring 142, and a wire 143 wound on the turntable 141. A rotating hole 1413 is provided on the turntable 141, and the rotating shaft 121 passes through the rotating hole 1413. The turntable 141 is rotatably connected to the rotating shaft 121 through the rotating hole 1413.

[0061] Understandably, the cable 143 is a data cable that can be used for charging and / or data transmission. A rotating hole 1413 is provided at the center of the turntable 141 in the winding structure 14. A rotating shaft 121 is provided on the second housing 12. The turntable 141 is sleeved on the rotating shaft 121 through the rotating hole 1413 and can rotate around the rotating shaft 121. When the cable 143 is pulled out, it drives the turntable 141 to rotate, causing the cable 143 to extend, and the spring 142 can wind it up to store energy. After the cable 143 is released, the spring 142 releases its elasticity, driving the turntable 141 to rotate and retract the cable 143. This achieves the extension and retraction of the cable 143 stored in the receiving space 13, making it convenient for the user.

[0062] Please see Figure 2 and Figure 3 Furthermore, a second circuit board 16 is provided on the side of the turntable 141 facing the first housing 11. The second circuit board 16 and the first housing 11 are respectively provided with a first limiting hole 161 and a second limiting hole 114. When the first housing 11 closes the second housing 12, the rotating shaft 121 passes through the rotating hole 1413, the first limiting hole 161, the central shaft hole 153 and the second limiting hole 114 in sequence, and abuts against the hole wall of the second limiting hole 114. The first circuit board 15 contacts the second circuit board 16 and conducts circuit.

[0063] Specifically, the second circuit board 16 is also a second PCB circuit board. The second circuit board 16 is fixed to the side of the turntable 141 facing the first housing 11 by means of protrusions 163 on its edge, and can rotate with the turntable 141. The side of the second circuit board 16 facing the circuit board is provided with five annular conductive tracks 164, and the back of the conductive tracks 164 can be electrically connected to the wire 143. The conductive end 152 on the first circuit board 15 is provided with three sets of conductive pins 1521, each set of conductive pins 1521 including five conductive pins 1521, each conductive pin 1521 protruding towards the second circuit board 16. After the first circuit board 15 is installed on the second circuit and the first housing is closed to the second housing 12, the protruding parts of the five conductive pins 1521 of each set of conductive pins 1521 on the first circuit board 15 can respectively contact the five conductive tracks 164 of the second circuit board 16. When the second circuit board 16 rotates with the turntable 141 and rotates relative to the first circuit board 15, the protruding parts of the five conductive pins 1521 of each group of conductive pins 1521 on the first circuit board 15 are always located in the corresponding conductive track 164 and always remain in contact, ensuring the conductivity between the first circuit board 15 and the second circuit board 16.

[0064] Understandably, by setting the conductive pins 1521 and conductive tracks 164 on the first circuit board 15 and the second circuit board 16, the conductive pins 1521 of the first circuit board 15 can slide in contact with the annular conductive track 164 to achieve zero physical bending, thereby achieving stable conductivity of the second circuit board 16 relative to the first circuit board 15 in the rotation state, avoiding the situation where the wire is easily broken due to repeated bending when the wire 143 is wound.

[0065] More specifically, the rotating shaft 121 on the second housing 12 can sequentially pass through the rotating hole 1413, the first limiting hole 161, the central shaft hole 153, and the second limiting hole 114, and abut against the wall of the second limiting hole 114. This allows the rotating shaft 121 to limit and fix the second housing 12, the second circuit board 16, the first circuit board 15, and the first housing 11, thereby improving the stability of the connection between the components and improving the stability of the contact and circuit conduction between the first circuit board 15 and the second circuit board 16. Furthermore, placing the rotating shaft 121 on the second housing 12 instead of the first housing 11 allows the rotating shaft 121 to maintain a relatively stable state for the turntable 141 and the second circuit board 16 during the disassembly or installation of the first housing 11 and the first circuit board 15, avoiding any impact on the turntable 141 and the second circuit board 16 during these processes. In addition, the relatively stable state of the turntable 141 and the second circuit board 16 maintained by the rotating shaft 121 also facilitates the installation and disassembly of the first housing 11 and the first circuit board 15.

[0066] Please see Figure 2 Furthermore, the telescopic cable storage device 1 also includes a stop member 17, a toggle member 18, and a spring piece 19; the stop member 17 and the toggle member 18 are stacked and rotatably connected to the first housing 11, and the turntable 141 has a plurality of first locking slots 1412 around the second circuit board 16 on one side of the second circuit board 16. The first locking slots 1412 are engaged with the stop member 17, and the spring piece 19 is engaged with the edge of the inner surface of the first housing 11 and abuts against the toggle member 18.

[0067] Specifically, to prevent the line 143 from accidentally shrinking during use, a stop member 17 and a toggle member 18 can be provided on the turntable 141. Multiple first locking slots 1412 can be provided on the turntable 141 around the second circuit board 16, and the stop member 17 can engage with the first locking slot 1412.

[0068] The specific usage process of the telescopic cable storage device 1: As the user pulls the cable 143 and extends it to a preset length, the movement of the cable 143 drives the turntable 141 to rotate, causing the spring 142 inside the turntable 141 to contract under force. At the same time, the first locking groove 1412 on the upper part of the turntable 141 moves closer to the stop member 17. As the pulling process of the cable 143 continues, the stop member 17 will engage with the closest first locking groove 1412 and abut against the groove wall of the first locking groove 1412, thereby... Under the abutment of the groove wall of the first locking slot 1412, the stop member 17 is driven to rotate. At this time, the end of the spring piece 19 that contacts the stop member 17 deforms due to the pressure caused by the rotation of the stop member 17. If the user continues to pull the cable 143, the stop member 17 can disengage from the current first locking slot 1412. When the user releases the cable 143, it quickly engages with the next closest first locking slot 1412 under the action of the spring piece 19, thereby preventing the turntable 141 from continuing to rotate and keeping the cable 143 at the current pulled-out length. If the user wants to retract the cable 143, the user needs to continue pulling the cable 143 to separate the locking member from the first locking slot 1412, and then release the cable 143. Under the action of the spring 142, the turntable 141 rotates in the opposite direction to wind the cable 143. This realizes the free extension and smooth retrieval of the cable 143 stored in the telescopic cable storage device 1, improving the user experience.

[0069] Understandably, by setting the stop member 17 and the toggle member 18, when the cable 143 is pulled out to a certain length, the user releases the data cable, and the stop member 17 will quickly enter the first locking slot 1412 under the action of the spring piece 19, effectively preventing the turntable 141 from continuing to rotate, thereby ensuring that the cable 143 remains in the current position and avoiding the cable 143 from being overstretched or contracted due to inertia.

[0070] Please see Figure 2 and Figure 6 Furthermore, a plurality of second slots 162 are provided at intervals on the boundary of the second circuit board 16, and the second slots 162 are correspondingly connected to the first slots 1412.

[0071] Understandably, a second locking groove 162 can be provided on the boundary of the second circuit board 16 at the position corresponding to the first locking groove 1412 on the turntable 141. The width of the second locking groove 162 can be the same as the width of the first locking groove 1412, thereby achieving mutual contact and communication between the boundaries of the first locking groove 1412 and the second locking groove 162. This prevents the locking member from being inserted into the first locking groove 1412. Even if the length of the locking member extending into the first locking groove 1412 is too long and exceeds the first locking groove 1412, it will only enter the second locking groove 162 and always maintain a non-contact state with the second circuit board 16. This further avoids the movement of the locking member affecting the circuit conduction between the second circuit board 16 and the first circuit board 15, thereby further ensuring the stability of the circuit conduction between the second circuit board 16 and the first circuit board 15.

[0072] Please see Figure 7 Furthermore, the stop member 17 has an arc-shaped protrusion 171 on the side facing away from the first housing 11, and the arc-shaped protrusion 171 abuts against the side of the turntable 141 where the second circuit board 16 is located.

[0073] Understandably, an arc-shaped protrusion 171 can be provided on the side of the stop member 17 facing away from the actuating member 18, so that the arc-shaped protrusion 171 abuts against the turntable 141. This allows the stop member 17 to form line contact with the surface of the turntable 141 when it rotates, thereby reducing the resistance generated by friction of the contact area while maintaining contact and relative rotation. At the same time, the arc-shaped protrusion 171 can also generate tangential guiding force during rotation, thereby improving the accuracy of the movement trajectory of the stop member 17.

[0074] Compared with the prior art, the telescopic cable storage device provided by this utility model has the following beneficial effects:

[0075] 1. A telescopic cable storage device provided in this embodiment of the present invention includes a first housing and a second housing. The first housing covers the second housing and forms a receiving space. A first circuit board and a winding structure with a cable wound inside are disposed in the receiving space. The first housing and the second housing are detachably connected. The first circuit board is located between the winding structure and the inner surface of the first housing and is detachably connected to the first housing. The first circuit board includes an input end. At least two through holes are provided on the first housing. The through holes are disposed along the edge of the side of the first housing facing away from the receiving space. The input end of the first circuit board is exposed through one of the through holes. By using a detachable first housing and a first circuit board, and by providing at least two through holes on the first housing to expose the input end of the first circuit board, at least two through holes with different orientations are reserved for the input end of the first circuit board, so as to meet the user's desire to install the first circuit board in the desired direction; it is also possible to remove the first housing and the first circuit board, and then reinstall the input end of the first circuit board from the currently aligned through hole to another through hole, thereby realizing the adjustment and change of the position of the input end of the first circuit board, so as to realize the change of the power connection direction of the input end, which is convenient to meet the user's power connection needs in different directions during use, and improves the flexibility of the direction adjustment of the input end of the telescopic cord storage device.

[0076] 2. In this embodiment of the invention, the first housing has three through holes, each pointing in a different direction; the three through holes are evenly spaced around the center of the first housing. By setting the three through holes evenly spaced and corresponding to different pointing directions, three through holes with different pointing directions can be provided for the input end of the first circuit board, thus providing three mounting positions for the input end of the first circuit board, which is more conducive to the user adjusting the exposed position of the input end according to the actual product being used.

[0077] 3. In this embodiment of the invention, the first housing has an opening on its side for the cable to pass through, and the through hole is positioned to avoid the direction of the opening. This achieves a misalignment between the opening for the exposed cable and the through hole, preventing the opening and the through hole from pointing in the same direction, thereby avoiding interference caused by the cable and the input end being connected to the device in the same direction.

[0078] 4. In this embodiment of the invention, the first circuit board has a central shaft hole, and three evenly distributed positioning holes are arranged around the central shaft hole. Three positioning posts are arranged on the inner surface of the first housing corresponding to the positioning holes. When the first housing is closed with the second housing, the positioning posts pass through the positioning holes. By setting three positioning posts corresponding to the three positioning holes, the first circuit board can be fixed in its current position after each installation, ensuring a stable electrical connection. Furthermore, the evenly distributed positioning holes prevent interference with the adjustment direction of the first circuit board during installation.

[0079] 5. The three positioning holes provided in this embodiment of the utility model are distributed in a triangular shape, thereby improving the stability and firmness of the first circuit board during each installation and fixing, and further ensuring the stable electrical connection of the first circuit board.

[0080] 6. In this embodiment of the present invention, a second circuit board is provided on the side of the turntable facing the first housing. The second circuit board and the first housing are respectively provided with a first limiting hole and a second limiting hole. When the first housing closes the second housing, the rotating shaft passes through the rotating hole, the first limiting hole, the central shaft hole and the second limiting hole in sequence, and abuts against the hole wall of the second limiting hole. Thus, the rotating shaft limits and fixes the second housing, the second circuit board, the first circuit board and the first housing, thereby improving the stability of the connection between the components and improving the stability of the contact between the first circuit board and the second circuit board and the circuit conduction.

[0081] 7. The telescopic cable storage device provided in this embodiment of the present invention further includes a stop member, a toggle member, and a spring piece; the stop member and the toggle member are stacked and rotatably connected to the first housing; one side of the turntable where the second circuit board is located has multiple first locking slots around the second circuit board; the first locking slots engage with the stop member; the spring piece engages with the edge of the inner surface of the first housing and abuts against the toggle member. By setting the stop member and the toggle member, when the cable is pulled out to a certain length, the user releases the data cable, and the stop member quickly enters the first locking slot under the action of the spring piece, effectively preventing the turntable from continuing to rotate, thereby ensuring that the cable remains in the current position and avoiding excessive extension or contraction of the cable due to inertia.

[0082] 8. In this embodiment of the invention, a plurality of second locking slots are spaced apart on the boundary of the second circuit board, and the second locking slots are correspondingly connected to the first locking slots. By correspondingly providing second locking slots on the second circuit board, it is possible to prevent the locking member from abutting against the second circuit board after being inserted into the first locking slot, thereby preventing the movement of the locking member from affecting the circuit conduction between the second circuit board and the first circuit board, and further ensuring the stability of the circuit conduction between the second circuit board and the first circuit board.

[0083] 9. In this embodiment of the invention, the stop member has an arc-shaped protrusion on the side facing away from the first housing, and the arc-shaped protrusion abuts against the side of the turntable where the second circuit board is mounted. By setting the arc-shaped protrusion to abut against the turntable, a line contact can be formed between the stop member and the surface of the turntable when the stop member rotates, reducing the resistance generated by friction between the two. At the same time, the arc-shaped protrusion can also generate a tangential guiding force during rotation, thereby improving the accuracy of the stop member's motion trajectory.

[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
