[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] The embodiment of the present application provides an earphone system, which includes a charging box 10 and earphones, wherein the charging box 10 is used to accommodate the earphones and charge the earphones after the earphones are placed in the charging box 10.

[0018] The relevant contents of the embodiment of the charging box 10 of the present application can be further referred to the detailed description below.

[0019] Combination Figure 1 to Figure 2, an embodiment of the present application provides a charging box 10 for earphones. The charging box 10 includes a box body 12, a box cover 11 and a bracket assembly. The box body 12 is used to accommodate the earphones, and a receiving groove 122 for accommodating the earphones is provided on the box body 12. The shape of the receiving groove 122 is configured to imitate the shape of the earphones, so that the receiving groove 122 can accommodate the earphones on the one hand, and on the other hand, when the earphones are placed in the receiving groove 122, the movement of the earphones can be restricted to play a positioning role. The box body 12 can also be provided with a battery, a power control board, etc. for managing the input and output of the power supply to charge the earphones.

[0020] The box cover 11 is rotatably connected to the box body 12, and can be rotated relative to the box body 12 between a closed position and an open position, so as to cover the earphone in the closed position and expose the earphone in the open position. The box cover 11 can cover the earphone when the earphone is placed in the box body 12, thereby protecting the earphone, reducing the possibility of the earphone falling out of the box body 12, and reducing the earphone from being disturbed by dirt such as dust.

[0021] The bracket assembly includes a bracket 124, which is movably arranged on the box body 12 and can move between a storage position and a supporting position along a preset direction relative to the box body 12, so that the bracket 124 at least partially protrudes from the box body 12 when in the supporting position, and is stored in the box body 12 when in the storage position. The preset direction of movement of the bracket 124 can be the thickness direction of the box body 12 or a direction at a certain angle to the thickness direction, which is not specifically limited here. Among them, when the bracket 124 is in the supporting position and the box cover 11 is in the open position, the protruding part of the bracket 124 and the box cover 11 are spaced apart from each other and are used together to support the mobile terminal. When the bracket 124 is in the storage position, it is stored in the box body 12, thereby avoiding interference between the bracket 124 and the box cover 11 or the earphone, and reducing the space occupied by the bracket 124.

[0022] Specifically, the bracket 124 forms a first fulcrum when it is in the supporting position, and the box cover 11 forms a second fulcrum when it is in the open position, and the first fulcrum and the second fulcrum jointly support the mobile terminal. Optionally, the bracket 124 can be engaged with the box body 12 during the rotation process and have an intermediate supporting position, and the bracket 124 can also form a first fulcrum with a different position when it is in the intermediate position. The box cover 11 can also be engaged with the box body 12 during the opening process to form an intermediate open position, and the box cover can form a second fulcrum with a different position when it is in the intermediate open position. Through the above-mentioned method, the positions of the first fulcrum and the second fulcrum can be changed to support the mobile terminal at different angles.

[0023] In some embodiments, the box cover 11 covers the box body 12 along a preset direction when it is in the closed position, and the bracket 124 is movably arranged on the box body 12 along the preset direction. The preset direction in which the box cover 11 covers can be the thickness direction of the charging box 10, or the length direction of the charging box 10. For example, the box cover 11 covers the box body 12 in a rotating manner, and the closing direction of the box cover 11 when it is in the closed position is the thickness direction of the charging box 10. The box cover 11 rotates along a preset rotation axis when it is opened, for example, one end of the box cover 11 is hinged to the box body 12, and the other end gradually moves away from the box body 12. Optionally, the rotation axis of the box cover 11 is perpendicular to the preset direction. In this way, the protruding position of the bracket 124 can cooperate with the box cover 11 in the open position, thereby forming a placement area for placing a mobile terminal.

[0024] In some embodiments, the box body 12 is provided with a mounting groove 123, and the box cover 11 covers the mounting groove 123 when in the closed position, and exposes the mounting groove 123 when in the open position. The bracket 124 is movably arranged in the mounting groove 123, and at least partially protrudes out of the mounting groove 123 when in the supporting position, so as to cooperate with the box cover 11 to support the mobile terminal, and is located in the mounting groove 123 when in the storage position, so as to hide and store the bracket 124 and reduce its volume protruding from the surface of the box body 12. Specifically, the box body 12 may include a shell and a top wall (shown but not marked). The top wall is provided with the aforementioned mounting groove 123, and the bracket 124 is movably arranged in the mounting groove 123. The bracket 124 is at least partially located outside the mounting groove 123 when in the supporting position, and is accommodated in the mounting groove 123 when in the storage position.

[0025] In some embodiments, the charging box 10 includes an elastic member 125 and a limit member 126. The elastic member 125 is disposed between the bottom wall of the mounting groove 123 and the bracket 124, and elastically supports the bracket 124 in a preset direction of movement of the bracket 124. The elastic member 125 can stretch or compress during the movement of the bracket 124, thereby driving the bracket 124 to move in a preset direction. For example, the user can press the bracket 124 to move toward the box body 12 to the storage position. During this process, the elastic member 125 can generate elastic compression to accumulate potential energy. In the process of the bracket 124 moving away from the box body 12 to the supporting position, the elastic member 125 can release potential energy, thereby driving the bracket 124 to move to the supporting position.

[0026] The limiting member 126 is connected to the bracket 124 in a limiting manner, and is used to limit the bracket 124 in a supporting position or a storage position when the bracket 124 is elastically supported by the elastic member 125. Specifically, the bracket 124 can move under the pressure of the elastic member 125 or the user, and the bracket 124 needs to be stably located in the supporting position or the storage position under the action of the elastic member 125 during the movement. The limiting member 126 can cooperate with the elastic member 125 to limit the bracket 124 in the supporting position or the storage position during the movement of the bracket 124. For example, the elastic member 125 can apply an elastic force away from the box body 12 to the bracket 124 in both the supporting position and the storage position. The limiting member 126 can apply a force close to the box body 12 to the bracket 124 when the bracket 124 is in the supporting position or the storage position to balance the elastic force of the elastic member 125, so that the bracket 124 can be stably in the supporting position or the storage position.

[0027] In some embodiments, the first end of the limiting member 126 is connected to the box body 12, and the second end is movably connected to the bracket 124. The bracket 124 can move under the pressure of the user and the elastic force of the elastic member 125. The bracket 124 is configured to allow the second end to move relative to the bracket 124 when moving between the supporting position and the storage position, so as to move between different limiting positions, and when the bracket 124 finally moves to the supporting position or the storage position under the action of the elastic member 125, it can be limited by the second end and stop moving.

[0028] Specifically, combined Figures 4 to 9, the preset direction of movement of the bracket 124 includes an entry direction from the supporting position to the storage position and an exit direction opposite to the entry direction. When the bracket 124 moves to the supporting position or the storage position, the second end is used to abut against the bracket 124 and apply a force in the entry direction to the bracket 124 to limit the bracket 124 from moving in the exit direction under the elastic support of the elastic member 125. One end of the limiting member 126 is rotatably connected to the box body 12, and the second end is movably connected to the bracket 124. The bracket 124 is provided with a first limiting portion 1241 and a second limiting portion 1242 spaced apart in the moving direction, and the first limiting portion 1241 is higher than the second limiting portion 1242 in the exit direction. The second end is used to abut against the first limiting portion 1241 or the second limiting portion 1242 in the entry direction to limit the bracket 124 in the storage position or the supporting position accordingly. When the second end of the stopper 126 abuts against the first stopper 1241, the bracket 124 is located at the storage position, and when the second end of the stopper 126 abuts against the second stopper 1242, the bracket 124 is located at the supporting position. The bracket 124 is configured to allow the stopper 126 to cancel the abutment with the first stopper 1241 or the second stopper 1242 by rotating relative to the box body 12, so that the second end can move relative to the bracket 124, thereby switching the abutment between the stopper 126 and the first stopper 1241 or the second stopper 1242.

[0029] In some embodiments, in combination Figure 4 The bracket 124 includes a supporting portion 124a and a moving portion 124b connected to each other, and the supporting portion 124a is movably arranged in the mounting groove 123. The aforementioned elastic member 125 can be arranged between the bottom wall of the mounting groove 123 and the supporting portion 124a. The moving portion 124b is provided with a slide groove 1240, and the second end of the limiting member 126 is movably embedded in the slide groove 1240. The slide groove 1240 has a side wall (shown in the figure but not marked) and a bottom wall (shown in the figure but not marked) connected to the side wall. The side wall is formed with a first limiting portion 1241 and a second limiting portion 1242, and in the direction of exiting the groove, the first limiting portion 1241 is higher than the second limiting portion 1242. The bracket 124 can cancel the abutment with the first limiting portion 1241 or the second limiting portion 1242 by rotating, and can move in the slide groove 1240. When the bracket 124 moves between the storage position and the supporting position, the second end can move between the first limiting portion 1241 and the second limiting portion 1242 along the slide groove 1240, and the slide groove 1240 can provide a guide for the movement of the second end of the limiting member 126. Optionally, the moving portion 124b faces the bottom of the installation groove 123, and the slide groove 1240 is opened in the moving portion 124b. The elastic member 125 is arranged between the bottom wall of the installation groove 123 and the supporting portion 124a.

[0030] In some embodiments, the slide groove 1240 is arranged in an annular shape, and the slide groove 1240 arranged in an annular shape can enable the second end of the limiter 126 to circulate in the slide groove 1240, so that the second end of the limiter 126 can circulate between the first limiter 1241 and the second limiter 1242, so as to realize the continuous transformation of the bracket 124 between the support position and the storage position under the operation of the user. The first limiter 1241 and the second limiter 1242 are used to limit the bracket 124 from moving in the direction of exiting the groove, that is, the limiter 126 needs to apply a force in the direction of entering the groove to the bracket 124 through the first limiter 1241 and the second limiter 1242. On this basis, the side wall of the slide groove 1240 includes an outer ring wall surface and an inner ring wall surface, and the outer ring wall surface surrounds the inner ring wall surface. Part of the wall surface of the outer ring wall surface is formed as the first limiter 1241, and part of the wall surface of the inner ring wall surface is formed as the second limiter 1242. The outer ring wall surface and the inner ring wall surface facing the groove exit direction avoid forming the first limiting portion 1241 and the second limiting portion 1242, so that the second end of the limiting member 126 can abut against the above-mentioned force to avoid forming the groove entry direction.

[0031] In some embodiments, the outer ring wall has a first concave section (illustrated in conjunction with the first limiting portion 1241) formed by being recessed in the direction of entering the groove, and the inner ring wall has a second concave section (illustrated in conjunction with the second limiting portion 1242) formed by being recessed in the direction of entering the groove, the first concave section is formed as the first limiting portion 1241, and the second concave section is formed as the second limiting portion 1242. The first concave section recessed in the direction of entering the groove is formed with a first bottom end and a first inclined side wall (not marked) by recessing, and under the elastic force of the elastic member 125 in the direction of exiting the groove, the second end of the limiting member 126 will be maintained at the first bottom end under the guidance of the first inclined side wall, and abut against the first bottom end to form a limiting force on the bracket 124. The second concave section that is recessed in the direction of entering the groove is formed with a second bottom end and a second inclined side wall (not marked) through the recess. Under the elastic force of the elastic member 125 in the direction of exiting the groove, the second end of the limiting member 126 will be maintained at the second bottom end under the guidance of the second inclined side wall, and abut against the second bottom end to form a limiting force on the bracket 124.

[0032] In some embodiments, the slide groove 1240 is arranged in an annular shape, and the slide groove 1240 includes a first groove section 1249a and a second groove section 1249b connected to each other in an annular manner, and the first groove section 1249a and the second groove section 1249b respectively form a first limit portion 1241 and a second limit portion 1242 at the connecting parts at both ends of each other. The movement of the limiter 126 between the first limit portion 1241 and the second limit portion 1242 can be realized by the first groove section 1249a and the second groove section 1249b. Among them, the slide groove 1240 is arranged so that when the second end moves from the first limit portion 1241 to the second limit portion 1242, it enters the first groove section 1249a to move, and when the second end moves from the second limit portion 1242 to the first limit portion 1241, it enters the second groove section 1249b to move. Among them, the second end of the limiter 126 moves in the first groove section 1249a along the first direction, so that the bracket 124 moves from the storage position to the support position. The second end of the stopper 126 moves in the second slot section 1249b along the second direction, so that the bracket 124 moves from the supporting position to the storage position. The first direction is opposite to the second direction. The first direction may be a slot entry direction, and the second direction may be a slot exit direction; or the first direction may be a slot exit direction, and the second direction may be a slot entry direction.

[0033] Furthermore, the slide groove 1240 is arranged in an annular shape, and the first groove section 1249a and the second groove section 1249b are connected end to end. In the above manner, the second end of the stopper 126 can continuously rotate clockwise or counterclockwise relative to the bracket 124 in the slide groove 1240, thereby switching between the first stopper 1241 and the second stopper 1242. In this way, the movement of the second end of the stopper 126 can form a cycle in the slide groove 1240, reducing the travel conflict problem of the stopper 126 sharing the groove section in other embodiments.

[0034] In some embodiments, the side wall of the slide groove 1240 includes an outer ring wall surface and an inner ring wall surface, and the outer ring wall surface is arranged at the periphery of the inner ring wall surface to enclose a first groove section 1249a and a second groove section 1249b. The first groove section 1249a and the second groove section 1249b communicate with the first limiting portion 1241 and the second limiting portion 1242, and the movement of the limiting member 126 between the first limiting portion 1241 and the second limiting portion 1242 can be realized by the first groove section 1249a and the second groove section 1249b. Part of the wall surface of the outer ring wall surface is recessed to form the first limiting portion 1241, and part of the wall surface of the inner ring wall surface is recessed to form the second limiting portion 1242. Specifically, the inner ring wall surface has a first concave surface section formed by recessing in the direction of entering the groove, and the first concave surface section is formed as the first limiting portion 1241. The outer ring wall surface has a second concave surface section formed by recessing in the direction of entering the groove, and the second concave surface section is formed as the second limiting portion 1242.

[0035] Among them, combined Figures 5 to 7, the outer ring wall is provided with a first guiding inclined surface 1245 in the first groove section 1249a, and the concave bottom of the first concave section is opposite to the first guiding inclined surface 1245 in the direction of exiting the groove, that is, the projection of the first stopper 1241 in the direction of exiting the groove is located on the first guiding inclined surface 1245. When the bracket 124 moves from the storage position to the support position, the first guiding inclined surface 1245 is used to abut the second end and guide the second end to enter the first groove section 1249a for movement. For example, when the bracket 124 moves from the storage position to the support position, the second end of the stopper 126 abuts against the first concave section, and then the user presses the bracket 124 to make the second end of the stopper 126 disengage from the first concave section. As the bracket 124 moves downward, the first guiding inclined surface 1245 abuts against the second end of the stopper 126 and guides the stopper 126 to rotate, thereby guiding the second end of the stopper 126 to move to the first groove section 1249a. Then the limiting member 126 can move in the first groove section 1249a, and the limiting member 126 cannot limit the bracket 124. After the user stops pressing, the bracket 124 moves upward under the action of the elastic member 125 until the second end of the limiting member 126 abuts against the second concave section, and the limiting member 126 limits the bracket 124 again.

[0036] Furthermore, combined with Figures 7 to 9 , the inner ring wall is provided with a second guiding inclined surface 1246 in the second groove section 1249b, and the concave bottom of the second concave section is opposite to the second guiding inclined surface 1246 in the direction of exiting the groove, that is, the projection of the second stopper 1242 in the direction of exiting the groove is located on the second guiding inclined surface 1246. When the bracket 124 moves from the supporting position to the storage position, the second guiding inclined surface 1246 is used to abut the second end and guide the second end to enter the second groove section 1249b for movement. For example, when the bracket 124 moves from the supporting position to the storage position, the second end of the stopper 126 abuts against the second concave section, and then the user presses the bracket 124 to make the second end of the stopper 126 disengage from the second concave section. As the bracket 124 moves downward, the second guiding inclined surface 1246 abuts against the second end of the stopper 126 and guides the stopper 126 to rotate, thereby guiding the second end of the stopper 126 to move to the second groove section 1249b. Then the limiting member 126 can move in the second groove section 1249b, and the limiting member 126 cannot limit the bracket 124. After the user stops pressing, the bracket 124 moves upward under the action of the elastic member 125 until the second end of the limiting member 126 abuts against the first concave section, and the limiting member 126 limits the bracket 124 again.

[0037] In some embodiments, in combination Figures 8 to 9, the inner ring wall surface also has a third guiding slope 1247 connected to the first concave section. The outer ring wall surface is provided with a guiding concave section (combined with the fourth limiting portion 1244) in the second groove section 1249b, and the concave bottom of the guiding concave section is opposite to the third guiding slope 1247 in the groove entry direction, that is, the projection of the guiding concave section in the groove entry direction is located on the third guiding slope 1247. When the bracket 124 moves from the supporting position to the storage position along the groove entry direction, the user can press the bracket 124 and overcome the elastic force of the elastic member 125, and the second end can abut the guiding concave section along the second groove section 1249b. After the second end of the limiting member 126 abuts the guiding concave section, it can also limit the bracket 124 and limit the further downward movement of the bracket 124, so that the user can feel that the bracket 124 moves downward to the preset position and can stop pressing the bracket 124. After the user stops pressing the bracket 124, when the bracket 124 moves in the direction of exiting the slot, the second end is separated from the abutment guide concave section, and as it continues to move upward, the second end of the stopper 126 abuts against the third guide slope 1247, and the third guide slope 1247 can abut against the second end and guide the second end to move to the first concave section under the elastic force of the elastic member 125. In this case, in the direction of entering the slot, the projection of the guide concave section is located on the third guide slope 1247, so that the bracket 124 can contact the third guide slope 1247 when moving upward.

[0038] In other embodiments, the inner ring wall surface further has a third guide slope 1247 connected to the first concave surface segment. A guide rib 128 (combined with Figure 4 ), the guide rib 128 is located in the second groove section 1249b, and one end of the guide rib 128 is higher than or flush with the highest point of the third guide slope 1247 in the groove exit direction, and the other end of the guide rib 128 extends obliquely toward the outer ring wall and away from the first limiting portion 1241. Optionally, the upper surface of the guide rib 128 is flush with the third guide slope 1247.

[0039] When the bracket 124 moves from the supporting position to the storage position, the second end can pass over the guide rib 128. After the second end passes over the guide rib 128 and the bracket 124 moves in the direction of exiting the groove, the guide rib 128 is used to abut the second end and guide the second end to move to the first concave section. The guide rib 128 allows the second end of the stopper 126 to move in the direction of exiting the groove in the second groove section 1249b, and restricts the second end of the stopper 126 from moving in the direction of entering the groove in the second groove section 1249b. In other words, when the bracket 124 moves upward under the action of the elastic member 125, the stopper 126 will not return to the second concave section under the action of the guide rib 128, but will abut against the third guide slope 1247 under the guidance of the guide rib 128 and move to the first concave section. In some embodiments, the limit member 126 is provided with a preload force, which can cause the second end of the limit member 126 to tend to move toward the bottom wall of the slide groove 1240, so that the second end of the limit member 126 can still abut against the bottom wall of the slide groove 1240 after passing over the guide rib 128, and the second end of the limit member 126 can abut against the upper surface of the guide rib 128 to guide the movement of the limit member 126.

[0040] In some embodiments, in combination Fig. 9 The bracket 124 is configured to be further movable to a trigger position relative to the box body 12, and the trigger position is lower than the storage position in the slot entry direction. The charging box 10 includes a function switch 127, which is disposed on the bottom wall of the mounting slot 123. The bracket 124 abuts against the function switch 127 when in the trigger position to trigger the function switch 127. The function switch 127 can be connected to the circuit board of the charging box 10, and triggering the function switch 127 can trigger the Bluetooth matching, switch and other functions of the charging box 10 or the earphone system.

[0041] In some embodiments, in combination Figure 4 and Figure 6, a third limiting portion 1243 is formed on the side wall, and the bracket 124 moves to the trigger position when the second end moves to the third limiting portion 1243. The third limiting portion 1243 is higher than the first limiting portion 1241 in the direction of exiting the slot. The third limiting portion 1243 is used to abut the second end to limit the bracket 124 from continuing to move in the direction of entering the slot. The third limiting portion 1243 faces the direction of entering the slot, and after the third limiting portion 1243 abuts against the second end of the limiting member 126, the second end of the limiting member 126 can provide a limiting force in the direction of exiting the slot. When the user presses the bracket 124, the second end of the limiter 126 first disengages from the first limiter 1241 or the second limiter 1242. As the user continues to press, the bracket 124 continues to move downward and gradually moves to the trigger position, and the second end of the limiter 126 abuts against the third limiter 1243 to limit the further downward movement of the bracket 124. In this way, the user can feel that the bracket 124 can no longer move, and knows that the bracket 124 moves to the trigger position and triggers the function switch 127. After the user cancels the pressing, the limiter 126 can switch to the first limiter 1241 or the second limiter 1242 in the manner of the above embodiment under the action of the elastic force.

[0042] In some embodiments, in combination Figure 4 and Figure 8 The side wall is also formed with a fourth limiting portion 1244, which is higher than the first limiting portion 1241 and lower than the third limiting portion 1243 in the direction of exiting the slot; when the second end moves to the fourth limiting portion 1244, the bracket 124 moves to a transition position between the trigger position and the storage position, and the bracket 124 is separated from the function switch 127 at the transition position; the fourth limiting portion 1244 is used to abut the second end to limit the bracket 124 from continuing to move in the direction of entering the slot. The fourth limiting portion 1244 faces the direction of entering the slot, and after the fourth limiting portion 1244 abuts against the second end of the limiting member 126, the second end of the limiting member 126 can provide a limiting force in the direction of exiting the slot.

[0043] The slide slot 1240 is configured such that when the second end moves from the first limiting portion 1241 to the second limiting portion 1242, it can first move to the third limiting portion 1243, and then move to the second limiting portion 1242, and when the second end moves from the second limiting portion 1242 to the first limiting portion 1241, it can first move to the fourth limiting portion 1244, and then move to the first limiting portion 1241. Specifically, when the bracket 124 is in the storage position, after the user presses the bracket 124, the second end of the limiting member 126 can be separated from the first limiting portion 1241, and then abut against the third limiting portion 1243, and the bracket 124 is in the trigger position. After the user releases the bracket 124, the bracket 124 can move in the direction of the groove under the action of the elastic member 125, and the second end of the limiting member 126 moves from the third limiting portion 1243 to the second limiting portion 1242, and the bracket 124 is transferred to the supporting position. After the user presses the bracket 124 again, the second end of the limiting member 126 is separated from the second limiting portion 1242, and then abuts against the fourth limiting portion 1244. After the user releases the bracket 124, the bracket 124 can move under the action of the elastic member 125, and the bracket 124 moves to the storage position. In this embodiment, the height of the third limiting portion 1243 is higher than the fourth limiting portion 1244, so when the second end of the limiting member 126 abuts against the third limiting portion 1243, the height of the bracket 124 is lower than the height of the bracket 124 when the second end of the limiting member 126 abuts against the fourth limiting member 126. In this way, the bracket 124 is only in the trigger position when the second end of the limiting member 126 abuts against the third limiting portion 1243. In other embodiments, the height of the third limiting portion 1243 is the same as the height of the fourth limiting portion 1244 , so that when the second end of the limiting member 126 abuts against the third limiting portion 1243 or the fourth limiting portion 1244 , the bracket 124 can be in the trigger position.

[0044] On the basis of the above embodiment, the third limiting portion 1243 is located in the first slot section 1249a, and the fourth limiting portion 1244 is located in the second slot section 1249b.

[0045] The following is a comprehensive exemplary introduction to the switching of the bracket 124 between the storage position and the support position. When the bracket 124 is in the storage position, the user can press the bracket 124 to overcome the elastic force of the elastic member 125 to move the bracket 124 in the direction of entering the groove, so that the second end of the limit member 126 is separated from the first limit portion 1241. The user continues to press the bracket 124, and the second end of the limit member 126 can abut against the first guide slope 1245. The limit member 126 rotates on the one hand under the action of the first guide slope 1245, and moves relative to the slide groove 1240 on the other hand. Under the pressure of the user, the second end of the limit member 126 can be located at the third limit portion 1243, and the bracket 124 is also in the trigger position. After the user releases the bracket 124, the bracket 124 moves in the direction of exiting the groove under the elastic force of the elastic member 125, and the second end of the bracket 124 can be separated from the third limiting portion 1243 and move in the first groove section 1249a until the second end of the bracket 124 abuts against the second limiting portion 1242, and the bracket 124 is thus limited, and the bracket 124 is in a supporting state. The user can press the bracket 124 again to move the bracket 124 in the direction of entering the groove, and the second end of the limiting member 126 is separated from the second limiting portion 1242 and abuts against the second guiding inclined surface 1246. Under the action of the second guiding inclined surface 1246, the limiting member 126 rotates and moves in the second groove section 1249b. As the bracket 124 continues to move, the second end of the limiting member 126 passes over the guiding rib 128 or the guiding concave section and abuts against the fourth limiting portion 1244. After the user releases the bracket 124, the bracket 124 moves in the direction of exiting the groove under the action of the elastic member 125, and the second end of the limiting member 126 can be separated from the fourth limiting portion 1244 and abut against the first limiting portion 1241 under the action of the third guiding slope 1247. Optionally, in some embodiments, the outer ring wall surface further includes a fourth guiding slope in the first groove section 1249a, and the fourth guiding slope can guide the second end of the limiting member 126 to the second limiting portion 1242.
