The damping member 45 can be an O-ring, which is sleeved on the first pipe portion and is located between the first pipe portion and the hole wall of the rotating shaft hole 3161, and is used to increase the damping between the first pipe portion and the hole wall of the rotating shaft hole 3161, so that the microphone 41 can rotate relative to the connecting seat 316 only when sufficient external force is applied. The outer cap 46 is snap-connected at the corner of the L-shaped bracket 42.

[0068] As Figure 1 and Figure 8 shown, the headphone provided by the embodiment of the present invention further includes a wireless communication component 5. The wireless communication component 5 includes an antenna 51, a base 52, and a communication circuit board 53. The base 52 penetrates through the side wall of the ear shell 31 and is detachably connected to the ear shell 31. The communication circuit board 53 is located in the accommodation cavity and is fixedly connected to the base 52. The antenna 51 is threadedly connected to the base 52 and is electrically connected to the main circuit board 33 through the communication circuit board 53.

[0069] Specifically, one end of the base 52 located inside the ear shell 31 is fixedly connected to the communication circuit board 53, and one end of the base 52 located outside the ear shell 31 is threadedly connected to the antenna 51. A nut 54 is sleeved on the base 52, and the nut 54 is located outside the ear shell 31. The base 52 is provided with a limiting surface, and the ear shell 31 is clamped between the limiting surface and the nut 54. In this way, the detachable connection between the base 52 and the ear shell 31, and the detachable connection between the base 52 and the antenna 51 are realized.

[0070] Optionally, a gasket 55, such as a flat gasket and / or a spring gasket, is further sleeved on the base 52. The gasket 55 is pressed between the nut 54 and the ear shell 31 to improve the connection reliability between the base 52 and the ear shell 31. Optionally, a sealing ring 56 is further sleeved on the base 52. The sealing ring 56 is pressed between the gasket and the ear shell 31 to realize the sealing protection of the wireless communication component 5.

[0071] As Figure 2 shown, in the embodiment of the present invention, the connecting member 12 is provided with two connecting portions 121, and two adaptors 13 are respectively connected to the two connecting portions 121. As Figure 6 shown, connecting shafts 30 are respectively provided on both sides of the ear cup 3, and the two connecting shafts 30 are rotatably and detachably clamped in the second card slots 1323 of the two adaptors 13 in a one-to-one correspondence.

[0072] Among them, one or both connecting parts 121 of the connecting piece 12 are provided with a first clamping groove 1201. On opposite sides of the peripheral side wall of the earcup 3, connecting shafts 30 are respectively protruded. The connecting shafts 30 are specifically arranged on the ear shell 31. Two adapters 13 connected to the connecting piece 12 are respectively arranged on both sides of the earcup 3 and are respectively clamped with the two connecting shafts 30. The two connecting shafts 30 are coaxially arranged, so that the earcup 3 can rotate relative to the adapter 13 around the connecting shaft 30 to adapt to the head shape of the wearer and improve the wearing comfort.

[0073] Specifically, the second clamping groove 1323 is a C-shaped groove, and the connecting shaft 30 is a flat shaft. The opening of the second clamping groove 1323 is larger than the minor diameter of the connecting shaft 30 and smaller than the major diameter of the connecting shaft 30. The minor diameter direction of the connecting shaft 30 is the same as the axial direction of the earcup 3, and the major diameter direction is perpendicular to the axial direction of the earcup 3.

[0074] Among them, the axial direction of the earcup 3 is consistent with the orientation of the sound output surface of the earcup 3. When the earcup 3 is installed in place, that is, when the sound output surfaces of the two earcups 3 are in a relative state, the opening of the second clamping groove 1323 forms a limit for the connecting shaft 30 to prevent the earcup 3 from disengaging from the second clamping groove 1323. When disassembling, the earcup 3 can be rotated by a certain angle and then taken out from the second clamping groove 1323. In this embodiment, while ensuring the reliable connection between the earcup 3 and the head beam 1, the quick disassembly of the two is realized. Further, a limiting part is provided at one end of the connecting shaft 30 away from the earcup 3 for restricting the axial movement of the connecting shaft 30 relative to the second clamping groove 1323.

[0075] It should be noted that the assembly structure of the adapter 13 and the earcup 3 in this embodiment is not limited to the structure described in the above embodiment. For example, the connecting shaft 30 is arranged on the back side of the earcup 3, that is, the side away from the sound output surface, and only one adapter 13 is provided. The specific structure of the adapter 13 can be adjusted adaptively based on the position of the connecting shaft 30, as long as it can meet the stable connection between the second clamping groove 1323 and the earcup 3.

[0076] In some alternative embodiments, a clamping member 120 is provided on at least one connecting part 121 of the connecting piece 12. As Figure 3 shown, the clamping member 120 is provided with a first clamping groove 1201 and a third clamping groove 1202. The third clamping groove 1202 is arranged at the bottom of the first clamping groove 1201. The connecting part 121 is clamped with the third clamping groove 1202.

[0077] Specifically, both the first card slot 1201 and the third card slot 1202 are C-shaped slots. The notch of the third card slot 1202 communicates with the bottom of the first card slot 1201. The shape of the third card slot 1202 is adapted to the connecting portion 121, the shape of the first card slot 1201 is adapted to the cable 2, and the cross-sectional dimension of the third card slot 1202 is smaller than that of the first card slot 1201. The connecting portion 121 is clamped in the third card slot 1202 to realize the detachable connection between the card connector 120 and the connecting member 12.

[0078] Optionally, the connecting member 12 is a circular steel bar structure, which is light in weight while ensuring its strength. The card connector 120 can be a structural member such as a plastic part or a flexible silicone part with certain elastic deformation and elastic recovery capabilities, so as to facilitate the installation and disassembly of the card connector 120 and the cable 2.

[0079] In the embodiment of the present invention, the head-mounted assembly 11 and / or the adapter 13 are detachably connected to the connecting member 12, so as to realize the detachable connection between the head-mounted assembly 11 and the adapter 13, and the head-mounted assembly 11 or the adapter 13 can be repaired or replaced separately.

[0080] In some alternative embodiments, the connecting member 12 is detachably connected to the adapter 13. Specifically, as Figure 3 shown, a second limiting portion 1211 is provided at the end of the connecting portion 121. As Figure 9 shown, a first hole section 1321 and a second hole section 1322 are connected in the adapter 13. The connecting portion 121 passes through the first hole section 1321 and the second hole section 1322 in sequence. The second limiting portion 1211 can slide and rotate in the second hole section 1322.

[0081] The adapter 13 has a first angular position and a second angular position relative to the connecting portion 121. When the second card slots 1323 of the two adapters 13 are clamped to the ear cups 3, the adapter 13 is in the second angular position.

[0082] When the adapter 13 is in the first angular position, the second limiting portion 1211 can slide in the first hole section 1321 and the first hole section 1321 can limit the rotation of the second limiting portion 1211. When the adapter 13 is in the second angular position, the first hole section 1321 can limit the second limiting portion 1211 in the second hole section 1322.

[0083] It should be noted that the sliding refers to the axial sliding of the connecting portion 121 along the hole, and the rotation refers to the rotation of the connecting portion 121 around the axis of the hole. The first hole section 1321 and the second hole section 1322 are coaxially arranged. The angular position of the adapter 13 relative to the connecting portion 121 refers to the angular position of the adapter 13 about the axis of the first hole section 1321 and the second hole section 1322.

[0084] Specifically, it is defined that the cross-section of the connecting portion 121 has a length and a width, and the length dimension is greater than the width dimension. The second hole section 1322 is a circular hole, and the diameter of the circular hole is greater than the maximum length of the cross-section of the connecting portion 121, so that the second limiting portion 1211 can freely slide and rotate within the second hole section 1322.

[0085] The first hole section 1321 is a rectangular hole. The length of the rectangle is greater than the maximum length of the cross-section of the connecting portion 121, and the width of the rectangle is greater than the maximum width of the cross-section of the connecting portion 121 and less than the maximum length of the cross-section of the connecting portion 121. When the length direction of the cross-section of the rectangular hole is consistent with the length direction of the cross-section of the connecting portion 121, that is, when the adapter 13 is in the first angular position, the connecting portion 121 can smoothly pass through the first hole section 1321 to reach the second hole section 1322, and the connecting portion 121 cannot rotate within the first hole section 1321. When the length direction of the cross-section of the rectangular hole is inconsistent with the length direction of the cross-section of the connecting portion 121, that is, when the adapter 13 is in the second angular position, the connecting portion 121 cannot be inserted into the first hole section 1321, nor can it retract from the second hole section 1322 into the first hole section 1321. It should be noted that the first hole section 1321 in this embodiment is not limited to a rectangular hole, and the second hole section 1322 is not limited to a circular hole, as long as the above-mentioned limiting function can be achieved.

[0086] Two connecting portions 121 of the same connector 12 are assembled and connected to two adapters 13. During assembly, the angles of the two adapters 13 are adjusted so that the two adapters 13 are inserted from the first hole section 1321 to the second hole section 1322 at the first angular position relative to the connecting portion 121. After the second limiting portions 1211 of the two connecting portions 121 are located in the second hole section 1322, the two adapters 13 are rotated to the second angular position, and then the earphone cup 3 is clamped in the second card slots 1323 of the two adapters 13. At this time, the earphone cup 3 restricts the two adapters 13 to the second angular position, and due to the existence of the second limiting portion 1211, the connecting portion 121 cannot withdraw from the second hole section 1322, realizing the limiting connection between the adapter 13 and the connector 12. When disassembling, first remove the earphone cup 3, and then rotate the adapter 13 to the first angular position, and the adapter 13 can be removed from the connector 12. Among them, the angular difference between the first angular position and the second angular position can be 90°.

[0087] In this embodiment, by adjusting the angle between the adapter 13 and the connecting portion 121, the quick installation and disassembly of the two can be realized. Not only can it ensure that the adapter 13 has a certain sliding stroke on the connector 12 to meet the wearing needs of different users, but also it can ensure that the adapter 13 will not fall off from the connector 12, improving the stability and reliability of the product.

[0088] Such as Figure 9As shown, in the embodiment of the present invention, the adapter 13 includes an adaptation part 132 and a flexible cap part 131. A first hole section 1321 and a second hole section 1322 are provided in the adaptation part 132. An annular flange 1324 is provided on the circumferential side of one end of the adaptation part 132. The flexible cap part 131 is sleeved on one end of the adaptation part 132, and an annular groove is provided on the inner side of the flexible cap part 131, and the annular groove is adaptively connected to the annular flange 1324. The flexible cap part 131 is provided with a second through hole 1311, and the connecting part sequentially passes through the second through hole 1311, the first hole section 1321 and the second hole section 1322. The hole wall of the second through hole 1311 is in close fit with the outer circumference of the connecting part.

[0089] Among them, the flexible cap part 131 is a flexible part not limited to a silicone rubber part, and has certain elastic deformation and elastic recovery capabilities. The size of the second through hole 1311 is smaller than the size of the connecting part. Due to the deformation performance of the flexible cap part 131, the connecting part can pass through the second through hole 1311 and be in close fit with the hole wall of the second through hole 1311. The adaptation part 132 can be injection molded with an ABS material.

[0090] Optionally, a plurality of annular flanges 1324 are provided at one end of the adaptation part 132, and the plurality of annular flanges 1324 are arranged at intervals along the axis direction of the first hole section 1321. Correspondingly, a plurality of annular grooves are provided on the inner side of the flexible cap part 131, and the plurality of annular grooves are arranged at intervals along the axis direction of the second through hole 1311. The plurality of annular grooves and the plurality of annular flanges 1324 are in one-to-one correspondence and cooperation to realize the reliable connection between the flexible cap part 131 and the adaptation part 132. Due to the limiting effect of the first hole section 1321 on the second limiting part 1211, the second limiting part 1211 cannot act on the flexible cap part 131, preventing the flexible cap part 131 from falling off.

[0091] It should be noted that an annular groove can also be provided on the adaptation part 132, and an annular flange can be provided on the inner side of the flexible cap part 131, and the fitting connection between the adaptation part 132 and the flexible cap part 131 can also be realized.

[0092] Optionally, one end of the second hole section 1322 away from the first hole section 1321 penetrates through the adaptation part 132, which can reduce the processing difficulty of the adaptation part 132. Correspondingly, a plug 133 is installed at one end of the second hole section 1322 away from the first hole section 1321 to prevent the connecting part 121 from passing out of the second hole section 1322. Optionally, the plug 133 is threadedly connected to the adaptation part 132, such as a screw.

[0093] In some alternative embodiments, the connecting member 12 is detachably connected to the head-mounted assembly 11. Specifically, such as Figure 1 、 Figure 2 and Figure 10As shown, the headband 1 also includes a fixing assembly 14. The fixing assembly 14 includes a fixing part and a first shell 141 and a second shell 142 respectively arranged on both sides of the end of the head-mounted assembly 11. The first shell 141 and the second shell 142 are interlocked with each other and are detachably connected to the head-mounted assembly 11 through the fixing part. The end of the head-mounted assembly 11 is accommodated in a cavity surrounded by the first shell 141 and the second shell 142. The connecting member 12 is detachably connected to the end of the head-mounted assembly 11, and passes through the cavity from the interlocking part of the first shell 141 and the second shell 142.

[0094] The two ends of the head-mounted assembly 11 are connected to a connector 12 through a fixing assembly 14, respectively. One of the first shell 141 and the second shell 142 is located on the inner side of the head-mounted assembly 11, and the other is located on the outer side of the head-mounted assembly 11. The two are buckled with each other and are detachably connected to the end of the head-mounted assembly 11. The first shell 141 and the second shell 142 are arranged to form an internal hollow cavity. The end of the head-mounted assembly 11 and one end of the connector 12 are accommodated in the cavity, and the other end of the connector 12 is located outside the cavity and connected to the adapter 13. The first shell 141 and the second shell 142 can be made of ABS material by injection molding.

[0095] When assembling the headband 1, first snap the connector 12 into place with the end of the head-mounted assembly 11, then snap the first shell 141 and the second shell 142 together, and connect the first shell 141 and the second shell 142 to the end of the head-mounted assembly 11 through the fixing member, thereby realizing a convenient and quick assembly of the head-mounted assembly 11, the fixing member 14, and the connector 12. When disassembling the headband 1, first remove the fixing member from the head-mounted assembly 11, then open the first shell 141 and the second shell 142, and then remove the connector 12 from the head-mounted assembly 11, thereby completing a convenient and quick disassembly of the head-mounted assembly 11, the fixing member 14, and the connector 12. By providing the fixing member 14, the time for installing and disassembling the headband 1 is shortened, and the convenience of product maintenance is improved.

[0096] In the embodiment of the present invention, Figure 2 , Figure 12 and Figure 13 As shown, the headband assembly 11 includes a headband support ring 111 and a covering member 112, wherein the headband support ring 111 is inserted through the covering member 112. A first through hole 110 is provided at the end of the headband assembly 11, and the first through hole 110 passes through the headband support ring 111 and the covering member 112. Figure 9 As shown, a connecting column 1411 is provided on one side of the first shell 141 facing the second shell 142 . The connecting column 1411 passes through the first through hole 110 . The fixing member passes through the second shell 142 and is threadedly connected to the connecting column 1411 .

[0097] Specifically, the first housing 141 and the second housing 142 are fastened to each other to form a cavity with an opening at one end, and the end of the head-mounted assembly 11 is inserted through the opening. As Figure 11 shown, a snap structure 114 is provided at the end of the head-mounted assembly 11, and one end of the connecting member 12 is snap-connected to the snap structure 114. As Figure 2 shown, after the first housing 141 and the second housing 142 are fastened, one end of the connecting member 12 and the snap structure 114 are received in the cavity, and the other end of the connecting member 12 passes through the cavity between the first housing 141 and the second housing 142.

[0098] Among them, the connecting column 1411 is provided with a first mounting hole, an internal thread is provided in the first mounting hole, the second housing 142 is provided with a second mounting hole corresponding to the first mounting hole, and the fixing member passes through the second mounting hole and the first mounting hole and is threadedly connected to the connecting column 1411. The fixing member is a threaded connecting member not limited to a screw.

[0099] Optionally, the number of the first through holes 110, the connecting columns 1411 and the fixing members is two each. The two connecting columns 1411 are respectively inserted through the two first through holes 110, and the two fixing members are threadedly connected to the two connecting columns 1411 one by one. In this way, the connection strength and reliability between the fixing assembly 14 and the head-mounted assembly 11 can be enhanced. Of course, more fixing members can also be provided, which can be set according to specific situations.

[0100] Optionally, the first housing 141 is located outside the head-mounted assembly 11, and the second housing 142 is located inside the head-mounted assembly 11, so that the fixing member is located inside the head-mounted assembly 11, which is more aesthetically pleasing.

[0101] Specifically, as Figure 12 shown, the covering member 112 includes a plastic sheet 1121, a rebound cotton 1122 and an outer cloth cover 1123. Plastic sheets 1121 are respectively provided on the inner side and the outer side of the support head ring 111, the rebound cotton 1122 is covered on the outer side of the plastic sheet 1121, and the outer cloth cover 1123 is covered on the outer side of the rebound cotton 1122 to form a tight fit. The first through hole 110 penetrates through the outer cloth cover 1123, the rebound cotton 1122, the plastic sheet 1121 and the support head ring 111.

[0102] Optionally, the rebound cotton 1122 and the plastic sheet 1121 can be bonded by back glue. The support head ring 111 is made of a stainless steel sheet. Optionally, the outer cloth cover is a good-quality cloth or a protein leather, and the plastic sheet is a PVC thin sheet. The good-quality cloth is wear-resistant, the rebound cotton 1122 has good comfort, and the PVC thin sheet ensures that the shape of the product will not change greatly, and the overall structure has good comfort and reliability.

[0103] Wherein, both ends of the support head ring 111 are located outside the covering member 112, and the buckle structure 114 is provided at the end of the support head ring 111. The fixing assembly 14 serves to connect the head-mounted assembly 11 and the connecting member 12 on the one hand, and also serves to decorate the end of the head-mounted assembly 11 on the other hand.

[0104] As Figure 12 shown, in the embodiment of the present invention, the head-mounted assembly 11 includes a support head ring 111 and a clamping block 115. The support head ring 111 is an elastic structure, and hook-shaped portions 1111 are respectively formed at both ends thereof. The clamping block 115 is disposed inside the hook-shaped portions 1111 and is clamped with the hook-shaped portions 1111 to form a buckle structure 114. The buckle structure 114 is received in a cavity surrounded by the first housing 141 and the second housing 142. A first through hole 1141 is formed by enclosing the clamping block 115 and the hook-shaped portions 1111, and a second through hole 143 is formed at the joint of the first housing 141 and the second housing 142. The connecting member 12 is passed through the first through hole 1141 and the second through hole 143.

[0105] Specifically, the hook-shaped portion 1111 includes a first extension portion, a bent portion, and a second extension portion that are connected in sequence. The first extension portion extends outward from the end of the covering member 112, and the second extension portion is disposed opposite to the first extension portion. The clamping block 115 is disposed between the first extension portion and the second extension portion, and encloses the bent portion to form the first through hole 1141. A first groove is provided on the side of the first housing 141, and a second groove is provided on the side of the second housing 142. When the first housing 141 and the second housing 142 are fastened, the first groove and the second groove are opposite to form the second through hole 143.

[0106] Wherein, the connecting member 12 is passed through the first through hole 1141 to realize the clamping connection between the connecting member 12 and the buckle structure 114. At the same time, the connecting member 12 is passed through the second through hole 143, so that the connecting member 12 passes through the fixing assembly 14 to be connected with the adapter 13.

[0107] Optionally, referring to Figure 12 , the clamping block 115 includes a body portion 1151 and a clamping portion 1152. The clamping portion 1152 protrudes from one side of the body portion 1151. The body portion 1151 is clamped between the body portion 1151 and the clamping portion 1152. The hook-shaped portion 1111 is provided with a bayonet 1112, and the clamping portion 1152 is passed through the bayonet 1112.

[0108] The hook 1111 is also elastic, and the block 115 can be removed from the hook 1111 by moving the hook 1111, so as to realize the convenient disassembly of the connector 12 and the buckle structure 114. When installing the block 115, the block 115 can be directly pushed into the hook 1111 from the opening between the second extension part and the first extension part, so that the block 115 is engaged with the bayonet 1112. When removing the block 115, the second extension part can be moved to enlarge the opening between the second extension part and the first extension part, so that the block 115 can be easily taken out from the hook 1111.

[0109] Specifically, a slope is provided on one side of the clamping portion 1152 close to the bent portion to form a trapezoidal clamping portion, which can reduce the resistance generated when the clamping block 115 is pushed into the hook 1111, and facilitate the installation of the clamping block 115. Correspondingly, the clamping opening 1112 is a rectangular hole.

[0110] Optionally, the bayonet 1112 is disposed at the first extension of the hook, so that the clamping block 115 and the bayonet 1112 can be more reliably connected. Optionally, the hook 1111 is bent toward the outside of the support head ring 111, so that the disassembly of the clamping block 115 can be facilitated.

[0111] Optionally, the supporting headband 111 is formed by bending a high-quality spring steel sheet as a whole, which not only ensures that the head-mounted assembly 11 has a good clamping force, but also improves the durability of the head-mounted assembly 11, reduces the cost of the headset, and improves the economy.

[0112] like Figure 14 As shown, in the embodiment of the present invention, the connecting member 12 includes a first limiting portion 122, a crossbeam 123 and a vertical beam. The two sides of the first limiting portion 122 are respectively connected to the crossbeams 123, and the end of the crossbeam 123 away from the first limiting portion 122 is connected to the vertical beam. Wherein, two buckle structures 114 are provided at each end of the head-mounted assembly 11. The first limiting portion 122 is limited between the two buckle structures 114 and between the first shell 141 and the second shell 142. The crossbeam 123 is passed through the first through hole 1141 and the second through hole 143 on the corresponding side, and the end of the vertical beam away from the crossbeam 123 is connected to the adapter 13.

[0113] Optionally, the connecting member 12 is a steel bar structure, and the first position limiting portion 122, the cross beam 123 and the vertical beam are formed by bending a whole steel bar, for example, by integrally bending 65Mn spring steel.

[0114] The connecting portion 121 described in the above embodiment is a vertical beam, and the second limiting portion 1211 is located at one end of the vertical beam away from the horizontal beam 123, and the second limiting portion 1211 protrudes from the side of the vertical beam. Optionally, the second limiting portion 1211 is formed by rolling on a vertical beam with a circular cross-section steel bar structure. Of course, the second limiting portion 1211 can also be a boss protruding from the side wall of the vertical beam.

[0115] Specifically, the two cross beams 123 connected to both sides of the first limiting part 122 are arranged along the same straight line, and the two vertical beams are perpendicular to the corresponding cross beams 123. The first limiting part 122 protrudes relative to the two cross beams 123. For example, the first limiting part 122 is a U-shaped structure, and both ends of the U-shaped structure are correspondingly connected to the two cross beams 123.

[0116] Both ends of the head-wearing assembly 11 are provided with two buckle structures 114. The two buckle structures 114 are arranged at intervals, and the interval width therebetween is equivalent to the width of the first limiting part 122. Both of the two buckle structures 114 are located in the cavity formed by the buckling of the first housing 141 and the second housing 142. Correspondingly, referring to Figure 5 , both ends of the support head ring 111 are provided with two hooks 1111. The two hooks 1111 are arranged at intervals and are formed by bending the same steel sheet.

[0117] The first limiting part 122 of the connecting member 12 is located between the two buckle structures 114, restricting the horizontal movement of the connecting member 12. The two cross beams 123 of the connecting member 12 respectively pass through the two first through holes 1141 of the two buckle structures 114, restricting the vertical movement of the connecting member 12. When the fixing assembly 14 is installed at the end of the head-wearing assembly 11, the first limiting part 122 is located between the first housing 141 and the second housing 142, restricting the rotation of the connecting member 12 around the cross beam 123. In this way, the clamping cooperation between the connecting member 12 and the two buckle structures 114 realizes the all-round limiting of the connecting member 12.

[0118] Among them, since there is a small gap between the first housing 141 and the second housing 142, the rotation angle of the connecting member 12 can be limited within a small range, enabling the earphone cup to adaptively adjust the angle within this angle range to adapt to the head shape of the wearer and improve the comfort.

[0119] In this embodiment, when the first housing 141 and the second housing 142 are fixed to the head-wearing assembly 11 through the fixing member, the fixing of the support head ring 111 and the covering member 112, the fixing of the head-wearing assembly 11 and the fixing assembly 14, and the fixing of the head-wearing assembly 11 and the connecting member 12 are completed synchronously, improving the production efficiency. When removing the connecting member 12 and the adapter 13 from the head-wearing assembly 11, only the fixing member and the connection between the buckle structure 114 and the connecting member 12 need to be removed.

[0120] Optionally, the first through hole 1141 and the second through hole 143 are coaxially arranged, and the cross beam 123 of the connecting member 12 passes through the first through hole 1141 and the second through hole 143 simultaneously. In this way, the structure of the connecting member 12 is relatively simple, and it can avoid the extrusion of the second through hole 143 of the fixing assembly 14 caused by the small-angle rotation of the connecting member 12, improving the connection reliability between the first housing 141 and the second housing 142.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
