[0068] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0069] Figure 1 is a schematic structural diagram of a first viewing angle of a camera device provided by this embodiment; Figure 2 is a schematic structural diagram of a second viewing angle of the camera device provided by this embodiment; Figure 3 yes Figure 1 A schematic diagram of the structure of the camera bracket from the first perspective; Figure 4 yes Figure 1 A schematic diagram of the structure of the second viewing angle of the middle camera bracket;

[0070] Figure 5 yes Figure 1 A state diagram of the assembly process of the transmission mechanism and the driving parts; Figure 6 yes Figure 5 Schematic diagram of some structures. Figures 1 to 6 As shown, this embodiment provides a camera device for installation in a housing (not shown in the figure) of a mobile terminal. The camera device includes a camera (not shown in the figure), a camera bracket 100, a transmission mechanism 200 and a driving member 300. The camera is installed on the camera bracket 100, and the transmission mechanism 200 includes a screw rod 210 and a screw rod nut 220. One end of the screw rod 210 is connected to the driving member 300 so as to drive the screw rod 210 to rotate around its own axis through the driving member 300. Figure 5 and Figure 6 As shown, the screw nut 220 includes a nut body 221 sleeved on the screw 210 and a first connecting portion 222 extending from the nut body 221 toward the camera bracket 100, and a convex column 225 parallel to the screw 210 is formed on the first connecting portion 222. Figure 2 and Figure 3 As shown, a hook 400 is formed on the camera bracket 100, and the hook 400 is clamped on the boss 225, so that the screw nut 220 can drive the camera bracket 100 to selectively pass through the shell of the mobile terminal or extend from the outside of the shell into the shell under the transmission of the screw 210.

[0071] It should be noted that the mobile terminal of this embodiment can be any mobile terminal device such as a smart phone, a smart watch, a tablet computer, a personal digital assistant, a sales terminal, a car computer, a desktop computer, a laptop computer, a smart TV, etc., and this embodiment does not limit this.

[0072] As described below, the mobile terminal includes a housing and a display screen disposed on the housing. The housing and the display screen enclose a receiving cavity of the mobile terminal. The camera device of this embodiment is accommodated in the receiving cavity, that is, inside the housing.

[0073] When the camera needs to be used, the driving member 300 drives the screw rod 210 to rotate. Since the nut body 221 of the screw rod nut 220 is threadedly connected to the screw rod 210, the screw rod nut 220 mounted on the screw rod 210 moves stably along the screw rod 210, thereby driving the camera bracket 100 to move away from the driving member 300, that is, to move toward the outside of the shell of the mobile terminal, until the camera on the camera bracket 100 is fully extended to the outside of the shell of the mobile terminal, and the camera exposed to the environment is used to capture images.

[0074] After the camera is used, the driving member 300 drives the screw rod 210 to rotate in the opposite direction, so that the screw nut 220 mounted on the screw rod 210 moves along the screw rod 210 toward the driving member 300, thereby driving the camera bracket 100 to move into the shell until the camera bracket 100 is completely received in the shell, and the driving of the driving member 300 is stopped.

[0075] Based on the above driving process, it can be known that the camera bracket 100 of the present invention is connected to the driving member 300 through the transmission mechanism composed of the screw nut 220 and the screw 210, so that the driving member 300 drives the camera bracket 100 more stably, so that the camera bracket 100 with the camera installed can move more stably to the outside of the shell or from the outside of the shell to the inside of the shell, thereby ensuring the normal operation of the camera and the effective storage of the camera.

[0076] In addition, in this embodiment, a boss 225 parallel to the axis of the screw 210 is provided on the first connection portion 222 of the screw nut 220, and a hook 400 matching the boss 225 is provided on the camera bracket 100. During assembly, the hook 400 is clamped on the boss 225 to achieve stable assembly of the camera bracket 100 and the screw nut 220 of the transmission mechanism 200. The above-mentioned connection method between the camera bracket 100 and the transmission mechanism 200 simplifies the connection structure between the camera bracket 100 and the transmission mechanism 200 while ensuring a stable connection between the two, making the assembly between the camera bracket 100 and the transmission mechanism 200 more convenient and quick, that is, only the hook 400 needs to be clamped on the boss 225, so that the camera bracket 100 can move stably with the movement of the screw nut 220.

[0077] The hook 400 and the camera bracket 100 of this embodiment are integrally formed as one piece, so as to improve the assembly efficiency between the hook 400 and the camera bracket 100, and at the same time enhance the connection strength between the hook 400 and the camera bracket 100, thereby ensuring the synchronous movement between the camera bracket 100 and the screw nut 220.

[0078] The hook 400 of this embodiment may specifically include two side walls arranged opposite to each other and a top wall connected between the two side walls, and the two side walls and the top wall together form a slot with an opening toward the inner bottom wall of the housing. During assembly, one of the side walls is connected to the camera bracket 100, and the other side wall extends from the top of the boss 225 of the screw nut 220 into between the boss 225 and the nut body 221, and the boss 225 is received in the slot 410 of the hook 400, so that the hook 400 is stably fixed on the boss 225.

[0079] Reference Figure 3As shown, in order to enable the hook 400 to be more stably hooked on the boss 225 , at least a portion of the inner surface of the hook 400 of this embodiment is configured as an arc surface that matches the outer surface of the boss 225 .

[0080] Specifically, the boss 225 of the present embodiment is a cylindrical structure, that is, the outer wall of the boss 225 is an arc-shaped structure. By setting at least a portion of the inner surface of the hook 400 as an arc-shaped surface matching the boss 225 to increase the contact area between the hook 400 and the boss 225, when the hook 400 is hooked on the boss 225, the contact between the inner surface of the hook 400 and the outer surface of the boss 225 is closer, so that the clamping connection between the hook 400 and the boss 225 is more stable, thereby ensuring the synchronous movement of the camera bracket 100 and the screw nut 220.

[0081] In specific implementation, the inner surface of the top wall of the hook 400 can be set as an arc surface that fits the outer surface of the boss 224. In some examples, the arc surface can also be extended to the inner surfaces of the two opposite side walls to further increase the contact area between the hook 400 and the outer surface of the boss 225.

[0082] Reference Figure 6 As shown, in this embodiment, a limiting portion 226 is formed on the outer wall of one end of the boss 225 away from the first connecting portion 222, and the hook 400 is located between the limiting portion 226 and the first connecting portion 222. In other words, the limiting portion 226 limits the movement of the hook 400 along the extension direction of the boss 225, effectively preventing the hook 400 from escaping from one end of the boss 225, and further improving the stability of the hook 400 on the boss 225.

[0083] Reference Figure 2 , Figure 5 and Figure 6As shown, the screw nut 220 of this embodiment further includes a second connection portion 223 extending from the nut body 221 toward the camera bracket 100. In other words, one end of the second connection portion 223 is connected to the nut body 221, and the other end extends in a direction away from the screw 210. The second connection portion 223 is arranged opposite to the first connection portion 223. The transmission mechanism of this embodiment further includes an elastic member 230, and the two ends of the elastic member 230 are respectively abutted against the boss 224 and the second connection portion 223. When the hook 400 is subjected to an external force toward the second connection portion 223 and is disengaged from the boss 225, for example, when it is disengaged from the limit portion 226, the hook 400 will compress the elastic member 230, and the elastic member 230 will further generate an elastic force toward the first connection portion 222 on the hook 400, thereby pushing the hook 400 to move to the boss 225 again, so that the hook 400 can be more stably fixed on the boss 224. In other words, the elastic member 230 plays an elastic buffering role for the hook 400. For example, after the screw nut 220 drives the camera bracket 100 to expose the outside of the mobile terminal, when the camera bracket 100 is slightly bumped, the camera bracket 100 will shrink a certain distance into the accommodating cavity of the mobile terminal, thereby preventing the camera bracket 100 from being damaged and extending the service life of the camera bracket 100. Among them, the elastic member 230 can be an annular spring.

[0084] It is understandable that the external force applied to the camera bracket 100 due to collision or the like is smaller than the elastic force of the elastic member 230 , so that the elastic member 230 can continue to rebound the hook 400 onto the protruding column 225 through the elastic force.

[0085] Reference Figure 1 and Figure 3 As shown, in order to improve the stability of the elastic member 230 in the direction perpendicular to the compression direction, a cover plate 500 is formed at the top of the hook 400 along the extension direction of the boss 225 in this embodiment. The cover plate 500 covers the boss 225 and part of the elastic member 230 to limit the end of the elastic member 230 close to the boss 225 from deflecting away from the bottom of the shell of the mobile terminal, thereby effectively preventing one end of the elastic member 230 from detaching from the boss 225.

[0086] Reference Figure 4 As shown, further, a notch 510 can be formed in the portion of the cover plate 500 located on the elastic member 230, and the notch 510 is arranged close to the nut body 221. In this way, it can be observed from the notch 510 whether one end of the hook 400 is well inserted into the gap between the boss 225 and the nut body 221. While ensuring the limitation of the elastic member 230, the hook 400 can also be quickly and effectively clamped on the boss 225.

[0087] In some examples, a limiting column 227 can also be formed on the end face of the boss 225 facing the second connecting portion 223, and one end of the elastic member 230 is sleeved on the limiting column 227, further limiting the movement of the end of the elastic member 230 close to the boss 225 in various diameter directions perpendicular to the axial direction of the elastic member 230, thereby ensuring the abutment stability between the elastic member 230 and the boss 225.

[0088] It is understandable that the first connection portion 222 and the second connection portion 223 of the screw nut 220 can be connected to the two ends of the nut body 221 along the extension direction of the screw 210. In some examples, in order to increase the spacing between the first connection portion 222 and the second connection portion 223, the present embodiment can extend a transition portion 224 along a direction parallel to the screw 210 on one side of the nut body 221 facing the hook 400, and one end of the first connection portion 222 and the second connection portion 223 are respectively connected to the two ends of the transition portion 224, so that the length of the elastic member 230 disposed between the first connection portion 222 and the second connection portion 223 can be increased, thereby improving the buffering effect on the camera bracket 100.

[0089] It is understandable that the distance between the first connection portion 222 and the second connection portion 223 can be adjusted by adjusting the extension length of the transition portion 224 .

[0090] Among them, the nut body 221, the first connecting part 222, the second connecting part 223 and the transition part 224 of this embodiment can be an integrally formed one-piece to enhance the structural strength of the screw nut 220, while also simplifying the assembly process of the screw nut 220, thereby improving the assembly efficiency of the camera device.

[0091] Reference Figure 1 , Figure 2 and Figure 5 As shown, the camera device of this embodiment also includes a fixed base 600, which includes a bottom wall 610 and a first retaining wall 620 and a second retaining wall 630 extending upward from the bottom wall 610, and the first retaining wall 620 and the second retaining wall 630 are respectively arranged at both ends of the bottom wall 610 along the moving direction of the screw nut 220.

[0092] The fixing base 600 is fixed in the shell of the mobile terminal. Specifically, a fourth connection portion 660 may be extended from the bottom wall 610 of the fixing base 600, and the fixing base 600 may be fixed to the shell of the mobile terminal through the fourth connection portion 660. For example, a screw hole may be provided on the fourth connection portion 660, and a thread groove may be provided on the shell of the mobile terminal accordingly, and the fixing base 600 and the shell are fastened together by screws inserted into the screw hole and the thread groove.

[0093] The transmission mechanism of this embodiment also includes a guide rod 240, the two ends of which are respectively fixed to the first retaining wall 620 and the second retaining wall 630, and the first connecting portion, the protruding column 225, the elastic member 230 and the second connecting portion 223 are all movably sleeved on the guide rod 240, so that when the driving member 300 drives the screw rod 210 to rotate around its own axis, the nut body 221 sleeved on the screw rod 210 can move along the axis of the screw rod 210, and at the same time, the first connecting portion 222 and the second connecting portion 223 connected to the nut body 221 are The portion 223 can move between the first baffle wall 620 and the second baffle wall 630 along the guide rod 240, while also ensuring that the elastic member 230 can be compressed along the extension direction of the guide rod 240, so that the hook 400 disposed on the boss 225 can drive the camera bracket 100 to move stably along the extension direction of the guide rod 240 without deviation to the left or right, thereby ensuring that the camera bracket 100 can accurately pass through the shell opening of the mobile terminal and extend out of the mobile terminal or enter the storage cavity of the mobile terminal from the outside.

[0094] In some examples, a mounting groove may be provided on the first retaining wall 620, a mounting hole may be provided on the second retaining wall 630, and a sixth connecting portion 241 may be provided at one end of the guide rod 240 close to the second retaining wall 630. For the convenience of description, in this embodiment, one end of the guide rod 240 close to the first retaining wall 620 is referred to as the first end, and one end of the guide rod 240 close to the second retaining wall 630 is referred to as the second end.

[0095] Reference Figure 5 and Figure 6 As shown, during the specific assembly, the first end of the guide rod 240 passes through the mounting hole of the second retaining wall 630 into the fixing seat 600 along the direction of arrow a, and then passes through the second connecting portion 223, the elastic member 230, the limiting column 227, the protruding column 225 and the first connecting portion 222 in sequence and is fixed in the mounting groove of the first retaining wall 620, and finally the fifth connecting portion 241 of the guide rod 240 is fixed on the second retaining wall 630 to complete the assembly between the guide rod 240 and the fixing seat 600. It can be understood that the guide rod 240 can be screwed between the first retaining wall 620 and the second retaining wall 630 along the direction indicated by arrow b.

[0096] Among them, the outer contour size of the sixth connecting part 241 is larger than the size of the mounting hole of the second baffle wall 630, so that after the guide rod 240 is assembled on the fixing seat 600, the sixth connecting part 241 is located on the surface of the second baffle wall 630 away from the first baffle wall 620, that is, the outer surface of the second baffle wall 630. In this way, the fifth connecting part 241 can be fixed on the outer surface of the second baffle wall 630 to achieve the assembly of the guide rod 240.

[0097] It is understandable that the sixth connection portion 241 can be welded to the outer surface of the second retaining wall 630, or fixed to the outer surface of the second retaining wall 630 by means of screws or the like.

[0098] The bottom wall 610 of the present embodiment is located at one end of the second retaining wall 630 and further forms a mounting portion 640 with a hollow structure inside. The mounting portion 640 and the second retaining wall 630 are arranged side by side in a direction perpendicular to the guide rod 240 .

[0099] The mounting portion 640 is a cylindrical member, and the driving member 300 is accommodated in the mounting portion 640, so that the driving member 300 is arranged side by side with the guide rod 240. The screw rod 210 of this embodiment is also arranged side by side with the guide rod 240, and the first end of the screw rod 210 extends into the mounting portion 640 and is connected to the driving member 300, and the second end of the screw rod 210 extends to the first retaining wall 620. Among them, a mounting groove can be opened on the first retaining wall 620, and the second end of the screw rod 210 can be movably clamped in the mounting groove. For example, a bearing can be installed in the mounting groove, and the second end of the screw rod 210 is sleeved in the bearing so that the screw rod 210 can rotate around its own axis. It can be understood that the mounting groove for fixing one end of the screw rod 210 is arranged opposite to the mounting portion 640, and the mounting groove for fixing the guide rod 240 is arranged opposite to the mounting hole on the second retaining wall 630, so that the guide rod 240 and the screw rod 210 are arranged side by side.

[0100] In this embodiment, the driver 300 is accommodated in the mounting portion 640 with a hollow structure to improve the stability of the driver 300 on the fixing seat 600. At the same time, the mounting portion 640 can also reduce the noise generated when the driver 300 is working. In the specific setting, the outer wall of the driver 300 can be set close to the inner wall of the mounting portion 640, that is, the inner size and shape of the mounting portion 640 match the outer contour size and shape of the driver 300, so as to ensure that the driver 300 will not shake in the mounting portion 640 during operation, thereby improving the shooting effect of the camera.

[0101] The driving member 300 of the present embodiment is a stepping motor. It is understandable that in other examples, the driving member 300 may also be a driving device such as a pneumatic cylinder or an oil cylinder.

[0102] Reference Figure 5 As shown, in order to enhance the structural strength of the mounting portion 640 for fixing the driving member 300, the fixing seat 600 of this embodiment may further include a reinforcing member 650, which includes an annular portion 651 sleeved on the mounting portion 640 and a plurality of reinforcing ribs 652 extending outward from the annular portion 651, and the plurality of reinforcing ribs 652 are attached to the outer wall of the mounting portion 640 at intervals around the axis of the mounting portion 640.

[0103] Among them, each reinforcing rib 652 extends along the axial direction of the mounting portion 640 to increase the contact area with the mounting portion 640 in the length direction, thereby enhancing the structural strength of the mounting portion 640, effectively avoiding damage to the mounting portion 640 caused by vibration generated by the driving member 300 during operation, and extending the service life of the mounting portion 640.

[0104] It is understandable that the extension length of the reinforcing ribs 652 can be adjusted according to the extension length of the mounting portion 640 , and the number of the reinforcing ribs 652 can be adjusted according to the diameter size of the mounting portion 640 .

[0105] In addition, the extension length of the mounting portion 640 of this embodiment is greater than the extension length of the driving member 300. Thus, during specific assembly, the driving member 300 is stored in the mounting portion 640 at a position away from the first retaining wall 620, and one end of the screw rod 210 extends into the mounting portion 640 and is connected to one end of the driving member 300, so that the mounting portion 640 also has a certain limiting effect on the screw rod 210, thereby ensuring the stability of the screw rod 210 on the fixing seat 600.

[0106] In order to effectively control the moving distance of the camera bracket 100, the camera device of this embodiment also includes a processor, a magnetic part and a Hall element. The processor, the magnetic part and the Hall element are not shown in the figure. The magnetic part is fixed on the camera bracket 100 and arranged side by side with the camera bracket 100 in a direction parallel to the inner bottom wall of the shell of the mobile terminal. The Hall element is used to be fixed on the shell of the mobile terminal, which is equivalent to the camera bracket 100 being fixed. The processor is electrically connected to the Hall element and the driving part respectively. The Hall element is used to sense the magnetic induction intensity, so that when the magnetic induction intensity reaches the preset magnetic induction intensity, the processor controls the driving part to stop driving the screw rod 210 to move. Among them, the magnetic part can be specifically a magnet, and the structure and working principle of the Hall element and the processor can be specifically referred to the prior art.

[0107] It can be understood that the preset magnetic induction intensity includes a first preset magnetic induction intensity and a second preset magnetic induction intensity, wherein the first preset magnetic induction intensity refers to the magnetic induction intensity sensed by the Hall element when the camera is completely exposed to the outside of the shell of the mobile terminal driven by the camera bracket; the second preset magnetic induction intensity refers to the magnetic induction intensity sensed by the Hall element when the camera bracket is completely retracted into the shell of the mobile terminal.

[0108] During specific operation, when the camera bracket 100 carries the camera and moves to the outside through the shell opening of the mobile terminal driven by the drive member 300 and the screw nut 220 of the transmission mechanism 200, the distance between the magnetic member fixed on the camera bracket 100 and the Hall element fixed in the shell gradually increases, so that the magnetic induction intensity sensed by the Hall element gradually decreases. When the magnetic induction intensity sensed by the Hall element reaches the first preset magnetic induction intensity, the camera is completely exposed to the outside of the shell of the mobile terminal, that is, it can take pictures. At this time, the Hall element transmits a signal to the processor, and the processor controls the drive member 300 to stop working.

[0109] Similarly, when the camera is not used, the driver 300 drives the camera bracket 100 to retract into the shell. When the magnetic induction intensity sensed by the Hall element reaches the second preset magnetic induction intensity, the camera bracket 100 is completely stored in the shell of the mobile terminal, and the processor controls the driver 300 to stop working.

[0110] In this embodiment, the magnetic component and the camera bracket 100 are arranged side by side in a direction parallel to the inner bottom wall of the shell of the mobile terminal. In other words, the magnetic component and the camera bracket 100 are arranged in a horizontal direction, thereby reducing the size occupied by the magnetic component in a direction perpendicular to the shell of the mobile terminal, thereby reducing the thickness of the entire mobile terminal and optimizing the aesthetic appearance of the product.

[0111] Reference Figure 3 and Figure 4 As shown, the camera bracket 100 of this embodiment may include a mounting portion 110 and a third connecting portion 120 connected to the mounting portion 110 when specifically configured. The camera is mounted on the mounting portion 110 , and the hook 400 is connected to the third connecting portion 120 .

[0112] In this embodiment, a card slot is opened on the surface of the bottom of the shell of the mounting portion 110 facing the mobile terminal, and the camera is specifically mounted in the card slot to save the size occupied by the mounting portion 110 in the thickness direction. Therefore, when designing the opening on the shell of the mobile terminal, it is possible to ensure that the camera bracket 100 carries the camera through the opening while reducing the size of the opening along the thickness direction of the mobile terminal, thereby reducing the entry of external dust and other debris into the shell through the opening, and also reducing the thickness of the mobile terminal.

[0113] The mounting portion 110 is provided with a wire hole 111 which is connected to a card slot for fixing the camera, so that after the camera is installed in the card slot, the signal line on the camera can be electrically connected to the circuit board inside the mobile terminal through the wire hole 111.

[0114] In this embodiment, a mounting groove 121 is formed on the third connecting portion 120, with the opening facing in a direction parallel to the inner bottom wall of the shell. The magnetic member is received in the mounting groove 121 to save the horizontal size occupied by the camera device, thereby reducing the horizontal size of the opening on the shell of the mobile terminal, and also providing suitable space for the installation of other parts inside the mobile terminal.

[0115] This embodiment also provides a mobile terminal, including a display screen, a housing, and the camera device as described above. Specifically, the display screen is arranged on the housing, the display screen and the housing together form a receiving cavity of the mobile terminal, the camera device is accommodated in the receiving cavity, an opening is arranged on the housing, and a driving member 300 of the camera device drives a camera bracket 100 through a transmission mechanism 200 to extend from the opening to the outside of the housing.

[0116] When the camera of the mobile terminal needs to be used, the driving member 300 of the camera device drives the screw rod 210 to rotate. Since the nut body 221 of the screw rod nut 220 is threadedly connected to the screw rod 210, the screw rod nut 220 mounted on the screw rod 210 moves stably along the screw rod 210, thereby driving the camera bracket 100 to move away from the driving member 300, that is, to move toward the outside of the shell of the mobile terminal, until the camera on the camera bracket 100 is fully extended to the outside of the shell of the mobile terminal, and then the camera exposed to the environment is used to capture images.

[0117] After the camera is used, the driving member 300 drives the screw rod 210 to rotate in the opposite direction, so that the screw nut 220 mounted on the screw rod 210 moves along the screw rod 210 toward the driving member 300, thereby driving the camera bracket 100 to move into the shell until the camera bracket 100 is completely received in the shell of the mobile terminal, and the driving of the driving member 300 is stopped.

[0118] The camera bracket 100 of the mobile terminal of this embodiment is connected to the driving member 300 through a transmission mechanism composed of a screw nut 220 and a screw 210, so that the driving member 300 drives the camera bracket 100 more stably, so that the camera bracket 100 with the camera installed can move more stably to the outside of the shell of the mobile terminal or from the outside of the shell to the inside of the shell, thereby ensuring the normal operation of the camera of the mobile terminal and the effective storage of the camera.

[0119] Reference Figure 1As shown, the mobile terminal of this embodiment also includes an annular positioning portion 700 fixed to the outside of the shell, and the annular positioning portion 700 is arranged around the outer periphery of the opening of the shell. When the camera bracket 100 moves from the inside of the shell of the mobile terminal to the opening through the shell, it can move outward along the annular positioning portion 700 blocked by the outer periphery of the opening, thereby preventing the camera bracket 100 from deflecting in a direction away from the axis of the opening, ensuring that the camera bracket 100 moves stably along the axis of the opening, which not only ensures the stability of the connection between the hook 400 on the camera bracket 100 and the screw nut 220, but also prevents the camera bracket 100 from deflecting left and right and causing damage to the opening of the shell.

[0120] In addition, the annular positioning portion 700 is arranged around one end of the opening outside the shell, which can also play a certain shielding role for liquid or dust flowing to the opening from the axial direction perpendicular to the opening.

[0121] It can be understood that the inner surface of the annular positioning portion 700 is flush with the inner surface of the opening, so that when a part of the camera bracket 100 passes through the opening, the inner surface of the annular positioning portion 700 can contact the outer surface of the camera bracket 100, thereby playing a better limiting role and ensuring that the camera bracket 100 moves along the axial direction of the opening.

[0122] The annular positioning portion 700 of this embodiment can be formed integrally with the shell of the mobile terminal. Of course, in some examples, the annular positioning portion 700 can also be connected to the shell of the mobile terminal in a detachable manner. Specifically, a fifth connecting portion 710 can be provided on the annular positioning portion 700, and a first screw hole can be provided on the fifth connecting portion 710. Correspondingly, a second screw hole coaxial with the first screw hole is provided on the shell, and the connection between the fifth connecting portion 710 and the shell is achieved by fasteners such as screws inserted in the first screw hole and the second screw hole, thereby achieving the fixing of the annular positioning portion 700.

[0123] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation modes, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned implementation modes, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present invention.
