[0049] The present application provides a pen body assembly. Specifically, the pen body assembly can be applied to functional pens such as electronic pens, beauty pens, and temperature measuring pens. The following will take the application of the pen body assembly to an electronic pen as an example for detailed description.

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the electronic pen according to an embodiment of the utility model. Figure 2 The electronic pen 10 of the present invention shows a schematic diagram of the structure of the charging interface. The electronic pen 10 includes a pen body assembly 1000 , and the pen body assembly 1000 includes a pen body 100 (also called a pen holder) and a shielding member 200 .

[0051] The pen body 100 is the main structure of the electronic pen 10, and includes a housing, mounting components contained in the housing, and various electronic devices and functional devices to realize various functions of the electronic pen 10. For example, the pen body 100 is provided with a charging interface 123, so that the electronic pen 10 can be charged through the charging interface 123 when the electronic pen 10 is low on power. The charging interface 123 may include any one or more of a Type-C interface, a USB interface, and a Lightning interface, which is not limited in this embodiment.

[0052] In order to prevent moisture and dust in the environment from entering the charging interface 123, a shielding member 200 is provided to cover the charging interface 123. The shielding member 200 can isolate the charging interface 123 from the external environment, prevent moisture and dust in the environment from entering the charging interface 123, and prevent the charging interface 123 from being corroded and damaged, thereby improving the service life of the electronic pen 10. At the same time, the shielding member 200 covers the charging interface 123 to prevent the charging interface 123 from being directly exposed, and the shielding member 200 can be designed to have the same color and pattern as the pen body 100, so as to achieve hiding of the charging interface 123 and improve the aesthetics of the electronic pen 10.

[0053] The shielding member 200 is movably disposed on the pen body 100, so that the shielding member 200 can move relative to the pen body 100 under the action of an external force, and the relative position of the shielding member 200 and the charging interface 123 can be changed. In the initial state, the shielding member 200 is in a position to cover the charging interface 123. When the electronic pen 10 needs to be charged, the shielding member 200 is moved to expose the charging interface 123.

[0054] The pen body assembly 1000 further includes a power source mechanism, which is used to drive the shielding member 200 to move relative to the pen body 100 so that the shielding member 200 exposes or covers the charging interface 123 .

[0055] The power source mechanism can be connected to a control terminal such as a circuit board in the pen body 100, so that the power source mechanism drives the shielding member 200 to move in response to the triggering of the circuit board. For example, during the use of the electronic pen 10, the control terminal can detect the remaining power of the electronic pen 10. When it is detected that the remaining power of the electronic pen 10 is low, the control terminal outputs a first driving signal to the power source mechanism, so that the power source mechanism drives the shielding member 200 to move relative to the pen body 100 and automatically exposes the charging interface 123, reminding the user to charge the electronic pen 10 in time. For another example, after the electronic pen 10 is charged, the control terminal can detect the plugging and unplugging of the charging harness. When it is detected that the charging harness is unplugged, the control terminal outputs a second driving signal to the power source mechanism, so that the power source mechanism drives the shielding member 200 to move relative to the pen body 100 and automatically covers the charging interface 123, so as to prevent the user from forgetting to operate and causing the charging interface 123 to be exposed for a long time.

[0056] Then, the pen body assembly of the embodiment of the present application, by providing a power source mechanism, the power source mechanism drives the covering member 200 to move relative to the pen body 100, so that the covering member 200 can automatically cover or expose the charging interface 123 without the need for manual operation by the user, which is convenient for the user to use. At the same time, it enriches the functionality of the electronic pen 10 and can improve the user experience.

[0057] In one embodiment, if Figure 2 As shown, the shielding member 200 is slidably connected to the pen body 100, and the power source mechanism is used to drive the shielding member 200 to slide relative to the pen body 100. The power source mechanism is used to drive the shielding member 200 to slide between a first position and a second position. In the first position, the orthographic projection of the shielding member 200 on the pen body 100 completely covers the charging interface 123, so that the shielding member 200 covers the charging interface 123. In the second position, the orthographic projection of the shielding member 200 on the pen body 100 is located outside the outline of the charging interface 123, so that the shielding member 200 reveals the charging interface 123.

[0058] The shielding member 200 may be slidably connected to the pen body 100 via a connecting member. For example, a slide rail may be provided on the pen body 100, and the shielding member 200 is slidably provided on the slide rail. The shielding member 200 may move along the slide rail under the drive of the power source mechanism and thus slide relative to the pen body 100. Of course, the shielding member 200 may also be directly slidably connected to the pen body 100 without providing a connecting member. The shielding member 200 may be directly sleeved on the outer peripheral wall of the pen body 100, so that the pen body 100 as a whole serves as a slide rail of the shielding member 200, thereby sliding relative to the pen body 100.

[0059] Of course, in other optional embodiments of the present application, the shielding member 200 can also be rotatably connected to the pen body 100. For example, in one embodiment, the pen body 100 is cylindrical, the shielding member 200 is designed to be tubular, and the shielding member 200 is sleeved on the outer peripheral wall of the pen body 100 and is rotatably connected to the pen body 100. The shielding member 200 is provided with a through hole that penetrates itself along the thickness direction, and the size of the through hole is greater than or equal to the size of the charging interface 123. Normally, the through hole of the shielding member 200 is completely staggered from the charging interface 123, so that the shielding member 200 can cover the charging interface 123. When the electronic pen 10 needs to be charged, the shielding member 200 is driven to rotate so that the through hole is opposite to the charging interface 123, so that the charging interface 123 can be exposed for charging.

[0060] It is understandable that the location of the charging interface 123 is specifically designed according to the design requirements of the electronic pen 10 . The charging interface 123 can be located in the middle of the pen body 100 or at the end of the pen body 100 .

[0061] In one embodiment, referring to Figure 2 As shown, the pen body 100 includes a first end 120 and a second end (not marked) that are opposite to each other along its axial direction, wherein a charging interface 123 is arranged at the first end 120, and the second end is used to form a pen tip of the electronic pen 10, and the electronic pen 10 can perform touch operations on a mobile communication device through the second end.

[0062] By setting the charging interface 123 at the first end 120 of the pen body 100 away from the pen tip, when the electronic pen 10 needs to be charged and used at the same time in special circumstances, the charging harness is connected to the first end 120 of the pen body 100, away from the user's hand, and will not hinder or interfere with the user's grip, so as to facilitate the user's use.

[0063] Moreover, to facilitate the assembly of the electronic pen 10, the outer shell of the pen body 100 is generally designed to be tubular, and the end of the pen body 100 is open. After the internal structure of the electronic pen 10 is installed, the end of the pen body 100 needs to be closed. Usually, a pen cap (also called a pen cover) is provided at the end of the pen body 100, and the charging interface 123 is provided at the first end 120, so the pen cap can be directly used as a shielding member 200 to cover the charging interface 123. By using the pen cap of the electronic pen 10 as the shielding member 200, the pen cap is not only used to close the end of the pen body 100, but also can cover the charging interface 123, and there is no need to make a separate shielding structure for the charging interface 123, which can simplify the structure of the electronic pen 10 and reduce the production cost of the electronic pen 10.

[0064] Please refer to Figure 3 , Figure 3The figure is a cross-sectional view of a partial structure of the pen body of the embodiment of the utility model. The first end portion 120 includes an end surface 121 and an outer peripheral surface 122 connected to the end surface 121. It can be understood that the end surface 121, i.e., the surface of the first end portion 120 located in the axial direction of the pen body 100, and the outer peripheral surface 122, i.e., the surface of the first end portion 120 located in the radial direction of the pen body 100. In order to realize automatic exposure and capping of the charging interface 123, the opening of the charging interface 123 is set on the outer peripheral surface 122.

[0065] In this embodiment, by setting the opening of the charging interface 123 on the outer peripheral surface 122 of the first end portion 120 instead of on the end surface 121, when the power source mechanism drives the shielding member 200 to move to expose the charging interface 123, the shielding member 200 can stop moving immediately as soon as the charging interface 123 is completely exposed, without having to completely detach from the first end portion 120, so that the shielding member 200 is still located on the first end portion 120, and the shielding member 200 is still supported by the pen body 100, so that after charging is completed, the power source mechanism can also drive the shielding member 200 to return to the initial position to cover the charging interface 123.

[0066] For example, in one embodiment, please combine Figure 1 And refer to Figure 4 , Figure 4 The shielding member 200 is a pen cap, and the shielding member 200 includes a base portion 210 and a shielding portion 220 disposed around the side edge of the base portion 210. The shielding portion 220 and the base portion 210 are enclosed to form a slide groove 230. The first end portion 120 of the pen body 100 is inserted into the slide groove 230, and the shielding member 200 can slide relative to the first end portion 120 through the slide groove 230.

[0067] Since the shielding member 200 is located in the axial direction of the pen body 100, the shielding member 200 is plugged into the first end portion 120, and the base portion 210 is opposite to the end surface 121 of the first end portion 120, and the shielding portion 220 is opposite to the outer peripheral surface 122 of the first end portion 120. When the shielding member 200 is in the first position, the base portion 210 is in contact with the end surface 121 to close the end of the pen body 100, and the shielding portion 220 completely covers the charging port 123.

[0068] Please refer again Figure 1 and Figure 2 The pen body 100 further includes a main body 110 , which is connected to the first end 120 and is coaxially arranged with the first end 120 , and the outer peripheral wall of the shielding portion 220 is flush with the outer peripheral wall of the main body 110 .

[0069] Specifically, the radial dimension of the first end portion 120 may be smaller than the radial dimension of the main body portion 110, that is, a step groove is formed between the first end portion 120 and the main body portion 110, and the step groove is arranged along the circumference of the first end portion 120. Then, when the first end portion 120 is inserted into the slide groove 230 of the shielding member 200 (pen cap), the shielding portion 220 of the shielding member 200 is located in the space where the step groove is located. By reasonably designing the thickness of the shielding portion 220, the outer peripheral wall of the shielding portion 220 can be flush with the outer peripheral wall of the main body portion 110, so that the surface of the electronic pen 10 is flat, which can improve the user's feel when using it, and at the same time improve the aesthetics of the electronic pen 10.

[0070] Please refer to Figure 3 and Figure 4 In one embodiment, the power source mechanism includes an electromagnet 310 and a first magnet 320. The electromagnet 310 is disposed on the pen body 100, and the electromagnet 310 includes an iron core 311 and a coil 312 wound around the iron core 311. The first magnet 320 is disposed on the shielding member 200, and the first magnet 320 is located in the axial direction of the iron core 311. The electromagnet 310 can generate an induced magnetic field when powered on, and generate magnetic attraction or repulsion through the induced magnetic field and the first magnet 320, so that the first magnet 320 is driven to move toward or away from the electromagnet 310 under the action of the magnetic attraction or repulsion, thereby driving the shielding member 200 to slide relative to the pen body 100.

[0071] For details, please refer to Figure 5 and Figure 6 , Figure 5 This is a cross-sectional view of the electronic pen of the present utility model showing a partial structure of the charging interface. Figure 6The cross-sectional view of the partial structure of the electronic pen capping charging interface of the present utility model embodiment. In the initial state, the electromagnet 310 is not energized, that is, in a power-off state, at this time, the first magnet 320 and the iron core 311 are magnetically attracted to each other, so that the shielding member 200 is maintained in the first position to cap the charging interface 123. When the electronic pen 10 needs to be charged, the electromagnet 310 is energized to generate an induced magnetic field. At this time, the magnetic field direction of the induced magnetic field is the same as the magnetic field direction of the first magnetic field, so that a magnetic repulsion force is generated between the electromagnet 310 and the first magnet 320. Under the action of the magnetic repulsion force, the first magnet 320 is pushed away from the electromagnet 310, thereby driving the shielding member 200 to slide and expose the charging interface 123. After the shielding member 200 moves to the second position, the electromagnet 310 is powered off. Since the first magnet 320 is far away from the iron core 311 at this time, the magnetic attraction between the first magnet 320 and the iron core 311 is not enough to drive the shielding member 200 to move, so that the shielding member 200 can be maintained in the second position without being affected by external forces. After the electronic pen 10 is charged, the electromagnet 310 is energized again, so that the electromagnet 310 generates an induced magnetic field. At this time, the magnetic field direction of the induced magnetic field is opposite to the magnetic field direction of the first magnetic field, so that a magnetic attraction force is generated between the electromagnet 310 and the first magnet 320. Under the action of the magnetic attraction force, the first magnet 320 is pushed to move toward the electromagnet 310, thereby driving the shielding member 200 to slide and cover the charging interface 123. After the shielding member 200 moves to the first position, the electromagnet 310 is powered off.

[0072] In order to better drive the shielding member 200 to slide relative to the pen body 100, the electromagnet 310 is disposed in the first end portion 120 and is disposed close to the end surface 121. Then, the distance between the electromagnet 310 and the first magnet 320 is relatively close, so that a larger magnetic force can be generated between the electromagnet 310 and the first magnet 320, thereby better driving the shielding member 200 to move. Please refer to Figure 3 The iron core 311 is arranged to extend axially along the pen body 100, the iron core 311 is coaxial with the axis of the pen body 100, and the side of the iron core 311 away from the pen tip is flush with the end face 121 or slightly protrudes from the end face 121. In order to fix the iron core 311, the pen body assembly 1000 also includes a fixing member (not marked), which is designed in a sleeve shape, and the fixing member is sleeved on the iron core 311 and connected and fixed to the pen body 100. The fixing member is provided with a winding groove (not marked), which is arranged along the circumference of the fixing member, and the coil 312 is wound in the winding groove. Correspondingly, please refer to Figure 4 The first magnet 320 is disposed on the base portion 210 of the shielding member 200 , and a groove (not shown) is disposed on one side of the base portion 210 facing the slide slot 230 . The first magnet 320 is bonded in the groove, and the first magnet 320 and the iron core 311 are disposed face to face.

[0073] It is understandable that the installation positions of the electromagnet 310 and the first magnet 320 can also be reversed. For example, in another embodiment of the present application, the electromagnet 310 can be set on the shielding member 200, and the first magnet 320 is set on the pen body 100. The electromagnet 310 generates a magnetic force between the induction magnetic field and the first magnet 320. Under the action of the magnetic force, the electromagnet 310 can move toward or away from the first magnet 320, thereby driving the shielding member 200 to slide relative to the pen body 100. The drawings of this embodiment are only illustrated by taking the former as an example, and cannot be regarded as limiting the present application.

[0074] As is known to all, when the winding of the coil 312 remains unchanged, the magnetic field direction of the induced magnetic field generated by the electromagnet 310 is related to the direction of the current flowing through the coil 312. By changing the direction of the current flowing through the coil 312, the magnetic field direction of the induced magnetic field can be changed. Then, in order to realize the two situations of driving the shielding member 200 to reveal the charging interface 123 and covering the charging interface 123 respectively, the current is controlled to flow through the coil 312 in opposite directions respectively, so that the directions of the induced magnetic fields generated by the electromagnet 310 are opposite. In one case, a magnetic repulsion force is generated between the electromagnet 310 and the first magnet 320, which can push the first magnet 320 to move away from the electromagnet 310, so that the shielding member 200 reveals the charging interface 123; in another case, a magnetic attraction force is generated between the electromagnet 310 and the first magnet 320, which can drive the first magnet 320 to move toward the electromagnet 310, so that the shielding member 200 covers the charging interface 123.

[0075] In this regard, in one embodiment, the pen body assembly 1000 also includes a circuit board (not shown in the figure), which is electrically connected to the electromagnet 310, specifically to the coil 312, and the circuit board is used to control the direction of the current flowing through the coil 312 to adjust the magnetic field direction of the induced magnetic field.

[0076] Among them, the electronic pen 10 includes a power source, such as a battery, and the circuit board is electrically connected to the power source. The circuit board can be provided with a detection circuit for detecting the remaining power of the power source. When it is detected that the power source is insufficient, the circuit board controls the power source to supply power to the electromagnet 310, thereby automatically driving the shielding member 200 to move to expose the charging interface 123, so as to remind the user to charge the electronic pen 10 in time.

[0077] A control button may also be provided on the pen body 100, and the control button is electrically connected to the circuit board. By pressing the control button, an electrical signal may be sent to the circuit board, so that the circuit board controls the power supply to supply power to the electromagnet 310 according to the electrical signal, thereby driving the shielding member 200 to move to expose the charging interface 123, so that the user can actively charge the electronic pen 10 according to his or her own needs.

[0078] To further facilitate the use of the user, the pen body assembly 1000 can also be wirelessly connected to a mobile device such as a mobile phone or a tablet, so as to wirelessly control the electromagnet 310 to drive the shielding member 200 to move through the mobile device. Specifically, the pen body assembly 1000 can include a first wireless communication module, which is arranged on a circuit board, and the first wireless communication module can be a wireless communication module such as Bluetooth or WiFi. A second wireless communication module is arranged inside the mobile device, and the electronic pen 10 wirelessly communicates with the mobile device through the first wireless communication module and the second wireless communication module, so that the electromagnet 310 can be energized according to the control signal sent by the mobile device to drive the shielding member 200 to move.

[0079] When the shielding member 200 is in the second position, that is, when the shielding member 200 exposes the charging interface 123 , the first magnet 320 is far away from the electromagnet 310 , and the magnetic attraction between the first magnet 320 and the iron core 311 is weak. The shielding member 200 is easily moved by slight vibration, affecting the normal charging of the electronic pen 10 .

[0080] In this regard, the pen body assembly 1000 also includes a limiting mechanism, which is used to limit the shielding member 200 to the second position, so that the shielding member 200 can be firmly maintained in the second position to prevent the shielding member 200 from moving due to vibration or slight external force, so as to ensure that the charging interface 123 can always be exposed during the charging process to avoid affecting the normal charging of the electronic pen 10.

[0081] Of course, the limiting mechanism can be configured to limit the shielding member 200 to the first position. Through the limiting action of the limiting mechanism and the magnetic attraction of the first magnet 320 and the iron core 311, the shielding member 200 can be more firmly limited to the first position to prevent the shielding member 200 from being moved by vibration or slight external force and causing the charging interface 123 to be exposed, thereby preventing moisture and dust in the environment from entering the charging interface 123.

[0082] For example, please refer to Figures 3 to 6 The limiting mechanism 400 includes a third magnet 420 and two second magnets 410. The two second magnets 410 are arranged on the pen body 100, and the two second magnets 410 are arranged at intervals along the axial direction of the pen body 100. The third magnet 420 is arranged on the shielding member 200. When the shielding member 200 moves to the first position, the third magnet 420 is magnetically matched with one of the second magnets 410; when the shielding member 200 moves to the second position, the third magnet 420 is magnetically matched with the other second magnet 410.

[0083] like Figure 3 As shown, the outer peripheral surface 122 of the first end portion 120 is provided with a first mounting groove (not shown), and the second magnet 410 is disposed in the first mounting groove. Figure 4As described above, the groove wall of the slide groove 230 of the shielding member 200 may be provided with a second mounting groove (not shown), and the third magnet 420 is provided in the second mounting groove, so that the second magnet 410 is prevented from protruding from the outer peripheral surface 122, and the third magnet 420 is prevented from protruding from the groove wall surface, so that the shielding member 200 can slide smoothly relative to the pen body 100 under the action of the driving force. Among them, the two second magnets 410 can be respectively provided on the front and rear sides of the charging interface 123 along the axial direction of the pen body 100, that is, one of the second magnets 410 is provided on the side of the charging interface 123 away from the end face 121, and the other second magnet 410 is provided on the side of the charging interface 123 close to the end face 121. For the convenience of explanation, the second magnet 410 away from the end face 121 is defined as the front end magnet block 411, and the second magnet 410 close to the end face 121 is defined as the rear end magnet block 412.

[0084] Specifically, in the initial state, that is, when the shielding member 200 is in the first position, the third magnet 420 and the front end magnetic block 411 are close to each other, and the magnetic polarity of the third magnet 420 and the front end magnetic block 411 are opposite, so that a magnetic attraction force is generated between the third magnet 420 and the front end magnetic block 411, thereby realizing magnetic attraction cooperation. At the same time, the first magnet 320 and the iron core 311 of the electromagnet 310 are magnetically attracted to each other. Then, under the action of two sets of magnetic attraction, the shielding member 200 can be firmly limited to the first position to prevent the shielding member 200 from being moved by vibration or slight external force, causing the charging interface 123 to be exposed, thereby preventing moisture and dust in the environment from entering the charging interface 123. When the electronic pen 10 is charged, the electromagnet 310 is energized to generate an induced magnetic field, so that a magnetic repulsion force is generated between the electromagnet 310 and the first magnet 320. The magnetic repulsion force is relatively strong and can overcome the magnetic effect between the front magnetic block 411 and the third magnet 420, so that the first magnet 320 can be pushed away from the electromagnet 310 and the shielding member 200 can be driven to move to expose the charging interface 123. When the shielding member 200 moves to the second position, the third magnet 420 and the rear magnetic block 412 are close to each other, and the magnetic polarities of the third magnet 420 and the rear magnetic block 412 are opposite, so that a magnetic attraction force is generated between the third magnet 420 and the rear magnetic block 412, and a magnetic attraction is achieved, so that the shielding member 200 can be stably limited to the second position, and the shielding member 200 is prevented from moving due to vibration or slight external force, so as to avoid affecting the normal charging of the electronic pen 10.

[0085] It is understandable that in another optional embodiment of the present application, two second magnets 410 may be arranged on the shielding member 200, and the two second magnets 410 are arranged at intervals along the axial direction of the pen body 100, and the third magnet 420 is arranged on the pen body 100, and the shielding member 200 may also be limited to the first position or the second position. The limiting principle is the same as that of the above embodiment, and will not be described in detail here. Among them, the drawings of this embodiment only illustrate the example of two second magnets 410 being arranged on the pen body 100 and the third magnet 420 being arranged on the shielding member 200, and cannot be regarded as a limitation of the present application.

[0086] Optional, see Figure 7 , Figure 7 The cross-sectional view of the electronic pen of another embodiment of the utility model shows a partial structure of the charging structure. In another embodiment, the limiting mechanism 400 includes a recessed portion 440 and two raised portions 430. The two raised portions 430 are arranged on one of the pen body 100 and the shielding member 200, and the two raised portions 430 are arranged at intervals along the axial direction of the pen body 100. The recessed portion 440 is arranged on the other of the pen body 100 and the shielding member 200. When the shielding member 200 moves to the first position, one of the raised portions 430 is plugged into the recessed portion 440; when the shielding member 200 moves to the second position, the other raised portion 430 is plugged into the recessed portion 440.

[0087] For example, two protrusions 430 are provided on the pen body 100 and the recessed portion 440 is provided on the shielding member 200. Figure 7 As shown, two protrusions 430 are formed protruding from the outer peripheral surface 122 of the first end portion 120, and the recessed portion 440 is recessed in the groove wall surface of the slide groove 230 of the shielding member 200. The two protrusions 430 can be respectively arranged at the front and rear sides of the charging interface 123 along the axial direction of the pen body 100, that is, one of the protrusions 430 is arranged on the side of the charging interface 123 away from the end surface 121, and the other protrusion 430 is arranged on the side of the charging interface 123 close to the end surface 121. For the convenience of explanation, the protrusion 430 away from the end surface 121 is defined as the first protrusion 431, and the second magnet 410 close to the end surface 121 is defined as the second protrusion 432.

[0088] Specifically, in the initial state, that is, when the shielding member 200 is in the first position, the first protrusion 431 is inserted into the recessed portion 440. The insertion and matching of the first protrusion 431 and the recessed portion 440 limits the freedom of the shielding member 200 to move along the axial direction of the pen body 100, and can limit the shielding member 200 to the first position, preventing the shielding member 200 from being moved by vibration or slight external force, thereby causing the charging interface 123 to be exposed, and preventing moisture and dust in the environment from entering the charging interface 123. When the electronic pen 10 is charged, the electromagnet 310 is energized to generate an induced magnetic field, so that a magnetic repulsion force is generated between the electromagnet 310 and the first magnet 320. The magnetic repulsion force is relatively strong and can overcome the limiting effect between the first protrusion 431 and the recessed portion 440, so that the first magnet 320 can be pushed away from the electromagnet 310 and drive the shielding member 200 to move to expose the charging interface 123. When the shielding member 200 moves to the second position, the second protrusion 432 is inserted into the recessed portion 440. The insertion and cooperation between the second protrusion 432 and the recessed portion 440 limits the freedom of the shielding member 200 to move axially along the pen body 100. The shielding member 200 can be limited to the second position to prevent the shielding member 200 from moving due to vibration or slight external force, thereby avoiding affecting the normal charging of the electronic pen 10.

[0089] The present application also provides an electronic pen 10 , which includes a pen body assembly 1000 conceived based on any of the above embodiments.

[0090] Since the electronic pen 10 adopts all the technical solutions of the pen body assembly 1000 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment.

Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
