The end of the winding drum is connected to the disk body. The outer diameter of the winding drum is smaller than the outer diameter of the disk body. The outer wall of the winding drum is used for winding the cable.

[0016] In yet another implementation of the present disclosure, the reset member is located inside the winding drum;

[0017] The reset member is a coil spring, a first end of which is connected to the inner wall of the housing and located at the axis of the winding drum, and a second end of which is connected to the winding drum.

[0018] In yet another implementation of the present disclosure, the wall of the winding drum has a wire fixing notch;

[0019] The wire fixing notch is used to accommodate the wire fixing protrusion of the cable to limit the movement of the wire fixing protrusion along a direction parallel to the disk body.

[0020] In yet another implementation of the present disclosure, the wall of the winding drum has a wire threading groove;

[0021] The threading groove is arc-shaped and coaxial with the winding drum. The notch of the threading groove is located at the end of the winding drum facing away from the disc body. The threading groove is used to accommodate the end of the cable.

[0022] The wire fixing notch is located at the wire threading groove.

[0023] In yet another implementation of the present disclosure, the disc body has a first wire fixing hole;

[0024] The first wire fixing hole is located at the wire fixing notch, and the first wire fixing hole is used to accommodate the wire fixing protrusion of the cable to limit the movement of the wire fixing protrusion in a direction perpendicular to the disk body.

[0025] In yet another implementation of the present disclosure, the cable reel further includes a limit disk;

[0026] The limiting disk is located on the side of the winding drum facing away from the disk body, and the limiting disk has a second wire fixing hole, which is opposite to the first wire fixing hole.

When the cable reel rotates along the outgoing direction, the cable reel, the toggle and the locking gear are in an unlocked state, so the cable reel can rotate. In this state, if the cable is subjected to external tension, the cable reel rotates along the outgoing direction, so that the cable is released from the housing. When the cable reel rotates along the reeling direction, if the cable reel rotates for the nth time, the cable reel, the toggle and the locking gear are in a locked state, so the cable reel cannot rotate. In this state, even if the cable is subjected to the driving force of the reset member, the cable reel cannot rotate in the reeling direction, so the cable cannot be retracted into the housing, thereby achieving cable locking. If the cable reel rotates for the n+1th time, the cable reel, the toggle and the locking gear are in an unlocked state, so the cable reel can rotate. In this state, the cable is driven by the resetting member, and the cable reel rotates in the wire-reeling direction, so that the cable is retracted into the housing.

[0036] Furthermore, since the locking gear and the toggle member are located on the same side of the cable reel and the locking gear and the cable reel are coaxially arranged, the internal space of the cable reel is relatively compact, which is conducive to the miniaturized design of the cable reel and increases the cable storage capacity.

DETAILED DESCRIPTION

[0060] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0061] An embodiment of the present disclosure provides an electronic device, which includes a cable module.

[0062] In this embodiment, the electronic device may be a mobile power supply, a charger, a wired socket, etc. The cable module is configured in the electronic device and can play a role in transmitting current or data.

[0063] Figure 1 A schematic diagram of a cable module according to an embodiment of the present disclosure is shown in FIG. Figure 1 In this embodiment, the cable module includes a cable 100 and a cable reel.

[0064] At least part of the cable 100 is located in the housing 10 and is wound on the cable reel 20, and one end of the cable 100 is connected to the cable reel 20. When the cable 100 extends out of the housing 10, the cable reel 20 rotates in the cable outlet direction, and when the cable 100 is retracted into the housing 10, the cable reel 20 rotates in the cable reeling direction. The cable outlet direction and the cable reeling direction are two opposite rotation directions of the cable reel 20.

[0065] The cable 100 may be a data cable, a charging cable, or the like.

[0066] Continue to see Figure 1 In this embodiment, the cable reel includes a housing 10 , a cable reel 20 , a toggle member 30 , a locking gear 40 and a reset member 50 .

[0067] The cable reel 20 is rotatably located in the housing 10. The toggle member 30 is located at a first side of the cable reel 20, and the toggle member 30 is swingably located in the housing 10, and the swing axis of the toggle member 30 is parallel to the rotation axis of the cable reel 20. The locking gear 40 is located at a first side of the cable reel 20, and the locking gear 40 is rotatably located in the housing 10, and the rotation axis of the locking gear 40 is coaxial with the rotation axis of the cable reel 20. The reset member 50 is located at a second side of the cable reel 20, and the reset member 50 is connected to the inner wall of the housing 10 and the cable reel 20, respectively.

[0068] When the cable reel 20 rotates in the line-out direction, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state. When the cable reel 20 rotates in the line-reeling direction for the nth time, the cable reel 20, the toggle member 30 and the locking gear 40 are in a locked state. When the cable reel 20 rotates in the line-reeling direction for the n+1th time, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state, so that the cable reel 20 rotates in the line-reeling direction driven by the reset member 50, and n is a positive integer.

[0069] The cable reel provided by the embodiment of the present disclosure includes a housing 10, and a cable reel 20, a toggle member 30, a locking gear 40 and a reset member 50 located in the housing 10. The cable reel 20 is used to wind the cable 100, and the cable reel 20 can rotate in the housing 10 along the outgoing direction and the reeling direction, and the outgoing direction and the reeling direction are two opposite directions. When the cable reel 20 rotates along the outgoing direction, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state, so the cable reel 20 can rotate. In this state, if the cable 100 is subjected to external tension, the cable reel 20 rotates along the outgoing direction, so that the cable 100 is released from the housing 10. When the cable reel 20 rotates along the reeling direction, if the cable reel 20 rotates for the nth time, the cable reel 20, the toggle member 30 and the locking gear 40 are in a locked state, so the cable reel 20 cannot rotate. In this state, even if the cable 100 is driven by the reset member 50, the cable 100 cannot be retracted into the housing 10 because the cable reel 20 cannot rotate in the reeling direction, thus achieving the locking of the cable 100. If the cable reel 20 rotates for the n+1th time, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state, so the cable reel 20 can rotate. In this state, the cable 100 is driven by the reset member 50, and the cable reel 20 rotates in the reeling direction, so that the cable 100 is retracted into the housing 10.

[0070] Furthermore, since the locking gear 40 and the shifting member 30 are both located on the same side of the cable reel 20 and the locking gear 40 and the cable reel 20 are coaxially arranged, the internal space of the cable reel is relatively compact, which is beneficial to the miniaturized design of the cable reel and increases the storage capacity of the cable 100.

[0071] It is worth noting that the external pulling force on the cable 100 mentioned above and the driving force on the cable 100 from the resetting member 50 are forces in opposite directions.

[0072] If the external pulling force is greater than the driving force of the reset member 50, the cable 100 has a tendency to drive the cable reel 20 to rotate in the cable outlet direction so as to extend out of the housing 10. Since the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state when the cable reel 20 rotates in the cable outlet direction, once the external pulling force is greater than the driving force of the reset member 50, the cable reel 20 can rotate and the cable 100 can extend out of the housing 10.

[0073] If the external pulling force is less than the driving force of the reset member 50, the cable reel 20 has a tendency to rotate in the winding direction to drive the cable 100 to retract into the housing 10. When the cable reel 20 rotates in the winding direction for the nth time, the cable reel 20, the toggle member 30 and the locking gear 40 are in a locked state. At this time, the cable reel 20 remains stationary and the cable 100 cannot be retracted into the housing. When the cable reel 20 rotates in the winding direction for the n+1th time, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state. At this time, the cable reel 20 rotates in the winding direction, thereby driving the cable 100 to retract into the housing 10.

[0074] Figure 2 It is a structural diagram of the cable module. Figure 2 The perspective is Figure 1 A direction perspective, combined with Figure 1 and Figure 2 In this embodiment, the housing 10 includes a first shell 110 and a second shell 120. The first shell 110 and the second shell 120 are connected, the inner wall of the first shell 110 has a first pin 111, the inner wall of the second shell 120 has a second pin 121, and the first pin 111 and the second pin 121 are spaced apart and coaxial with each other.

[0075] The cable reel 20 is rotatably sleeved on the first pin shaft 111 , and the locking gear 40 is rotatably sleeved on the second pin shaft 121 .

[0076] In the above implementation, the first pin shaft 111 and the second pin shaft 121 provide installation bases for the cable reel 20 and the locking gear 40, respectively. Since the first pin shaft 111 and the second pin shaft 121 are coaxially arranged with each other, the coaxial arrangement between the cable reel 20 and the locking gear 40 is ensured. In addition, since the first pin shaft 111 and the second pin shaft 121 are respectively located on the inner walls of the first shell 110 and the second shell 120, the internal space of the housing 10 can be more fully utilized, so that the arrangement of the cable reel 20 and the locking gear 40 is more reasonable.

[0077] In this embodiment, the first shell 110 and the second shell 120 are buckled together, so that the inner wall of the first shell 110 and the inner wall of the second shell 120 are opposite to each other, so as to form the inner space of the housing 10 together.

[0078] Exemplarily, the first housing 110 and the second housing 120 are connected by screws.

[0079] See also Figure 2 In this embodiment, the inner wall of the second shell 120 has a support column 122, and the end of the support column 122 facing away from the second shell 120 is opposite to one side of the winding reel 20.

[0080] During the rotation of the cable reel 20, if the cable reel 20 shakes unnecessarily, the cable reel 20 will abut against the end of the support column 122. The end of the support column 122 supports the cable reel 20 and effectively prevents the cable reel 20 from shaking more significantly.

[0081] It is worth noting that there is a small gap, such as 1-2 mm, between the end of the support column 122 facing away from the second housing 120 and one side of the cable reel 20. In this way, the support column 122 will not affect the normal rotation of the cable reel 20, and can also support the shaking cable reel 20 in time.

[0082] Continue to see Figure 2 In this embodiment, the inner wall of the housing 10 has a guide groove 123, and the extension direction of the guide groove 123 is consistent with the swing trajectory of the toggle member 30. The outer wall of the toggle member 30 has a guide platform 320, which is located on the side of the toggle member 30 facing away from the winding reel 20, and the guide platform 320 is movably located in the guide groove 123.

[0083] In the above implementation, since the extension direction of the guide groove 123 is consistent with the swing trajectory of the toggle member 30, when the guide platform 320 moves in the guide groove 123, the guide groove 123 can guide the guide platform 320, thereby avoiding errors in the swing trajectory of the toggle member 30. In this way, the toggle member 30 can swing to the correct position, thereby having good cooperation with the winding drum 20 and the locking gear 40, thereby improving the reliability of the winding device.

[0084] The foregoing describes the arrangement of the cable reel 20 and the locking gear 40 in the housing 10. By arranging the cable reel 20 and the locking gear 40 in the above manner, the required installation space can be effectively saved, which is conducive to the miniaturization design of the cable reel and increases the cable 100 storage capacity of the cable reel.

[0085] The following is an introduction to the manner in which the cable reel 20 stores the cable 100 .

[0086] Figure 3 The assembly diagram between the cable reel 20 and the cable 100 is shown in FIG. Figure 3 In the present embodiment, the cable reel 20 includes a reel body 210 and a cable drum 220 .

[0087] The winding drum 220 is located on the side of the disk 210 facing away from the locking gear 40 , and is coaxial with the disk 210 . The end of the winding drum 220 is connected to the disk 210 . The outer diameter of the winding drum 220 is smaller than the outer diameter of the disk 210 . The outer wall of the winding drum 220 is used to wind the cable 100 .

[0088] In the above implementation, the disc body 210 is the main body of the cable reel 20, which is rotatably connected to the first spool. The cable reel 220 is used to wind the cable 100. Since the outer diameter of the cable reel 220 is smaller than the outer diameter of the disc body 210, the cable 100 can be accommodated at the angle between the outer wall of the cable reel 220 and one side of the disc body 210, which effectively ensures the accommodation stability of the cable 100. In addition, since the cable reel 220 is located on the side of the disc body 210 facing away from the locking gear 40, the cable 100 will not interfere with the locking gear 40 and the toggle member 30.

[0089] Continue to see Figure 3 In this embodiment, the wall of the winding drum 220 has a wire fixing notch 223. The wire fixing notch 223 is used to accommodate the wire fixing protrusion 1100 of the cable 100 to limit the movement of the wire fixing protrusion 1100 in a direction parallel to the disc body 210.

[0090] The wire fixing protrusion 1100 protrudes from the outer wall of the cable 100 , and the wire fixing protrusion 1100 can be snapped into the wire fixing notch 223 , limiting the movement of the wire fixing protrusion 1100 in a direction parallel to the disk body 210 , thereby improving the installation stability of the cable 100 on the winding drum 220 .

[0091] Exemplarily, the wire fixing notch 223 passes through the inner wall and the outer wall of the winding drum 220 . When the wire fixing protrusion 1100 is inserted into the wire fixing notch 223 , a pair of side surfaces of the wire fixing protrusion 1100 are flush with the inner wall and the outer wall of the winding drum 220 .

[0092] Such a design can prevent the wire fixing protrusion 1100 from protruding from the inner wall or the outer wall of the winding drum 220 , thereby preventing interference with other components or affecting the winding of the wire fixing protrusion 1100 on the winding drum 220 .

[0093] In this embodiment, the wall of the cable drum 220 has a threading groove 222, which is arc-shaped and coaxial with the cable drum 220. The notch of the threading groove 222 is located at the end of the cable drum 220 facing away from the disk body 210, and the threading groove 222 is used to accommodate the end of the cable 100. The wire fixing notch 223 is located at the threading groove 222.

[0094] The cable reel 220 is similar to a C-shaped structural member. During the assembly of the cable 100 , the end of the cable 100 is inserted into the threading groove 222 from the notch of the threading groove 222 until the end of the cable 100 extends into the bottom of the threading groove 222 , and the wire fixing protrusion 1100 is also inserted into the wire fixing notch 223 .

[0095] In the above implementation, the threading groove 222 is formed by using the wall thickness of the cable drum 220, which can effectively improve the space utilization, facilitate the miniaturization design of the cable reel, and increase the cable 100 storage capacity of the cable reel.

[0096] In this embodiment, the wall of the winding drum 220 has a wire entry notch 221 , and the end of the wire threading groove 222 in the length direction is located in the wire entry notch 221 .

[0097] In the above implementation, since the cable 100 is wound on the outer wall of the cable drum 220 , the end of the cable can enter the threading groove 222 by using the cable entry notch 221 , which is beneficial to the routing of the cable 100 .

[0098] In this embodiment, the disk body 210 has a first wire fixing hole 211 located at the wire fixing notch 223 . The first wire fixing hole 211 is used to accommodate the wire fixing protrusion 1100 of the cable 100 to limit the movement of the wire fixing protrusion 1100 in a direction perpendicular to the disk body 210 .

[0099] In the above implementation, the wire fixing notch 223 is used to accommodate the side of the wire fixing protrusion 1100, and the first wire fixing hole 211 is used to accommodate one end of the wire fixing protrusion 1100. The wire fixing notch 223 and the first wire fixing hole 211 are combined to more stably clamp the wire fixing protrusion 1100.

[0100] In this embodiment, the cable reel also includes a limit disk 60, which is located on the side of the cable reel 220 facing away from the disk body 210. The limit disk 60 has a second wire fixing hole 610, which is opposite to the first wire fixing hole 211. The second wire fixing hole 610 is used to accommodate the wire fixing protrusion 1100 of the cable 100 to limit the movement of the wire fixing protrusion 1100 in a direction perpendicular to the disk body 210.

[0101] In the above implementation, the second wire fixing hole 610 is used to accommodate the other end of the wire fixing protrusion 1100 . The wire fixing notch 223 , the first wire fixing hole 211 , and the second wire fixing hole 610 are combined to more stably clamp the wire fixing protrusion 1100 .

[0102] Exemplarily, the limiting plate 60 is a circuit board, and the circuit board is used to be electrically connected to the cable 100 .

[0103] In the above implementation, the limit plate is designed as a circuit board, so that the limit plate 60 has both the limit function and the integrated circuit function, thereby effectively simplifying the internal structure of the cable module and facilitating miniaturization design.

[0104] Figure 4 is a schematic diagram of the assembly of the reset member 50, combined with Figure 4In this embodiment, the reset member 50 is located inside the winding drum 220, the reset member 50 is a coil spring, the first end of the reset member 50 is connected to the inner wall of the housing 10, and the first end of the reset member 50 is located at the axis of the winding drum 220, and the second end of the reset member 50 is connected to the winding drum 220.

[0105] In the above implementation, the reset member 50 is used to provide a driving force for driving the cable reel 20 to rotate in the line-retrieving direction. Since the reset member 50 is a coil spring, when the cable reel 20 rotates in the line-delivering direction, the coil spring is compressed, thereby accumulating elastic potential energy, and then when it is necessary to drive the cable reel 20 to rotate in the line-retrieving direction, the elastic potential energy is released and converted into a driving force.

[0106] In addition, since the reset member 50 is accommodated in the winding drum 220, the internal space of the winding drum 220 can be further utilized, which is conducive to realizing a miniaturized design.

[0107] Figure 5 is a schematic diagram of the assembly between the toggle member 30 and the housing 10, Figure 1 and Figure 5 In this embodiment, the reel further includes an elastic member 70. One end of the elastic member 70 is connected to the inner wall of the housing 10, and the other end of the elastic member 70 is connected to the toggle member 30, and the connection between the elastic member 70 and the toggle member 30 is located at a position of the toggle member 30 away from its own swing axis.

[0108] In the above implementation, the elastic member 70 is connected between the housing 10 and the toggle member 30, and can use its own elastic force to reset the toggle member 30 to the initial position. In addition, since the connection between the elastic member 70 and the toggle member 30 is located at a position of the toggle member 30 away from its own swing axis, the elastic member 70 has a large force arm during the process of driving the toggle member 30, which can ensure the driving of the toggle member 30.

[0109] Exemplarily, the elastic member 70 is a coil spring.

[0110] In this embodiment, the outer edge of the toggle member 30 has a first mounting column 330, the inner wall of the outer shell 10 has a second mounting column 124, the second mounting column 124 is located on the inner wall of the second shell 120, and the two ends of the elastic member 70 are respectively hooked on the first mounting column 330 and the second mounting column 124.

[0111] In this embodiment, a surface of the toggle member 30 facing away from the cable reel 20 has a support platform 310 , and a surface of the support platform 310 facing away from the toggle member 30 is opposite to the inner wall of the housing 10 .

[0112] During the swinging process of the toggle member 30, if the toggle member 30 shakes unnecessarily, the support platform 310 will abut against the inner wall of the outer shell 10, that is, against the inner wall of the second shell 120. The support platform 310 and the inner wall of the outer shell 10 support each other, effectively preventing the toggle member 30 from shaking more significantly.

[0113] It is worth noting that there is a small gap, such as 1-2 mm, between the support platform 310 and the inner wall of the housing 10. In this way, the housing 10 will not affect the normal swing of the toggle member 30, and can also support the shaking toggle member 30 in time.

[0114] See again Figure 1 The disc body 210 has a shifting gear 230 on one side facing away from the winding drum 220 . The shifting gear 230 is coaxial with the disc body 210 . The shifting gear 230 is used to drive the shifting member 30 to swing so that the shifting member 30 is meshed with the locking gear 40 .

[0115] In the above implementation, since the shifting gear 230 is coaxial with the disc body 210 , the shifting gear 230 can rotate together with the winding disc 20 , thereby driving the shifting member 30 to swing.

[0116] Figure 6 The assembly diagram between the toggle member and the locking gear is shown in Figure 1. Figure 6 In this embodiment, the toggle member 30 includes a frame 340, a first locking swing arm 350, a second locking swing arm 360 and a toggle swing arm 370. The frame 340 is pivotally connected to the housing 10. The first locking swing arm 350, the second locking swing arm 360 and the toggle swing arm 370 are arranged at intervals along the circumference of the frame 340. The first locking swing arm 350 and the second locking swing arm 360 are respectively located on opposite sides of the toggle swing arm 370. The toggle swing arm 370 can mesh with the toggle gear 230, so that the toggle member 30 is driven to swing through the cooperation between the toggle gear 230 and the toggle swing arm 370. The first locking swing arm 350 has a locking notch 351 on a side facing the disk body 210.

[0117] The locking gear 40 includes a plurality of gear teeth 410, the number of the gear teeth 410 is an even number, a tooth groove is provided between two adjacent gear teeth 410, one of the two adjacent tooth grooves has a locking boss 420, and the other of the two adjacent tooth grooves does not have a locking boss 420. The locking boss 420 matches the locking notch 351. When the first locking swing arm 350 is inserted into the tooth groove, if the tooth groove has a locking boss 420, the locking boss 420 can be inserted into the locking notch 351, so that the first locking swing arm 350 is inserted into the tooth groove in place. If the tooth groove does not have a locking boss 420, the first locking swing arm 350 can still be inserted into the tooth groove in place. When the second locking swing arm 360 is inserted into the tooth groove, if the tooth groove has a locking boss 420, the locking boss 420 will interfere with the second locking swing arm 360, resulting in the second locking swing arm 360 being unable to be inserted into the tooth groove in place. If the tooth groove does not have a locking boss 420, the second locking swing arm 360 can be inserted into the tooth groove in place.

[0118] Exemplarily, the number of the gear teeth 410 is six, the number of the tooth grooves is six, and three of the tooth grooves have locking bosses 420 .

[0119] Figure 7 This is a schematic diagram of the cable module. Figure 7 ,exist Figure 7 In the figure, starting from the upper left corner, there are 5 different states along the direction of the hollow arrows, which are described below one by one.

[0120] (1) The toggle member 30 is in the initial position, and the toggle swing arm 370 is meshed with the locking gear.

[0121] (2) The cable 100 is extended outward by the external pulling force, and the cable reel 20 is driven to rotate in the direction of the cable outlet. The toggle gear 230 rotates together with the cable reel 20 to drive the toggle member 30 to swing by toggle the swing arm 370. As the toggle member 30 swings, the first locking swing arm 350 is inserted into the tooth groove of the locking gear 40 until it is inserted into the tooth groove and the toggle swing arm 370 is separated from the toggle gear 230. At this time, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state, and the cable 100 can be pulled out freely.

[0122] (3) Release or reduce the external tension on the cable 100, so that the external tension is less than the driving force of the reset member 50. The reset member 50 drives the cable reel 20 to rotate in the opposite direction (the nth rotation in the winding direction), and the toggle swing arm 370 re-engages with the locking gear, so that the toggle member 30 swings in the opposite direction. As the toggle member 30 swings, the second locking swing arm 360 is inserted into the tooth groove of the locking gear 40. Since there is a locking boss 420 in the tooth groove, the second locking swing arm 360 cannot be inserted into the tooth groove, resulting in the swing arm being unable to detach from the toggle gear 230. At this time, the cable reel 20, the toggle member 30 and the locking gear 40 are in a locked state, and the cable 100 is locked.

[0123] (4) The cable 100 is extended outward by external tension, and the cable reel 20 is driven to rotate in the cable outlet direction. The coordination between the cable reel 20, the shifting member 30 and the locking gear 40 is similar to the above-mentioned point (2), which will not be described in detail here.

[0124] (5) Release or reduce the external tension on the cable 100, so that the external tension is less than the driving force of the reset member 50. The reset member 50 drives the cable reel 20 to rotate in the opposite direction (the n+1th rotation in the winding direction), and the toggle swing arm 370 re-engages with the locking gear, so that the toggle member 30 swings in the opposite direction. As the toggle member 30 swings, the second locking swing arm 360 is inserted into the tooth groove of the locking gear 40. Since there is no locking boss 420 in the tooth groove, the second locking swing arm 360 can be inserted into the tooth groove in place, and the toggle swing arm 370 is disengaged from the toggle gear 230. At this time, the cable reel 20, the toggle member 30 and the locking gear 40 are in an unlocked state, and the cable 100 can be freely retracted.

[0125] It is worth noting that whenever the first locking swing arm 350 or the second locking swing arm 360 is inserted into the tooth groove, the locking gear 40 will be moved by one grid, so that when the first locking swing arm 350 is inserted into the tooth groove for the nth time, there is a locking boss 420 in the tooth groove, and when it is inserted into the tooth groove for the n+1th time, there is no locking boss 420 in the tooth groove. When the second locking swing arm 360 is inserted into the tooth groove for the nth time, there is a locking boss 420 in the tooth groove, and when it is inserted into the tooth groove for the n+1th time, there is no locking boss 420 in the tooth groove. Since the first locking swing arm 350 has a locking notch 351, the first locking swing arm 350 can be inserted into the tooth groove in place every time. Since the second locking swing arm 360 does not have a locking notch 351, the second locking swing arm 360 cannot be inserted into the tooth groove in place when it is inserted into the tooth groove for the nth time, and can only be inserted into place when it is inserted into the tooth groove for the n+1th time.
