Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0050] As mentioned in the background technology, the bottom of the existing cleaning equipment is usually provided with a cleaning mechanism. When the cleaning equipment completes the cleaning task or needs to overcome an obstacle, the cleaning mechanism needs to be lifted to leave the surface to be cleaned. However, the lifting process of the cleaning mechanism is very laborious, and a high-power motor is required to provide sufficient pulling force for the cleaning mechanism to achieve the lifting of the cleaning mechanism, which results in a heavier overall weight of the cleaning equipment and increases the manufacturing cost. To this end, the inventor of the present application has designed a new cleaning device, by which the problem that the lifting process of the cleaning mechanism in the prior art is relatively laborious and requires the use of a high-power motor, resulting in a heavier overall weight of the cleaning equipment and a higher manufacturing cost can be solved. The cleaning device of the present application will be described in detail below in conjunction with the accompanying drawings.

[0051] It should be noted that the "height direction of the fuselage 10" in this application refers to the height direction of the fuselage 10. Figure 1 The direction indicated by the letter X in the figure, “the length direction of the lifting lever” refers to the direction of the attached Figure 2 The direction indicated by letter Y in the figure is the thickness direction of the lifting lever. Figure 2 The direction indicated by the letter Z in the figure, the “first direction” refers to the direction of the adjacent Figure 2 The direction indicated by the letter Y.

[0052] See also Figures 1 to 8As shown, according to an embodiment of the present application, a cleaning device is provided, which includes a body 10, a cleaning mechanism 20 and a driving mechanism 30.

[0053] Among them, the cleaning mechanism 20 is movably arranged at the bottom of the fuselage 10, and the cleaning mechanism 20 has a first position that is lifted along the height direction of the fuselage 10 to be away from the surface to be cleaned, and a second position that is lowered along the height direction of the fuselage 10 to be close to the surface to be cleaned; the driving mechanism 30 is arranged on the fuselage 10, and the driving mechanism 30 includes a first driving component 40, a lifting member 50 and a lever lifting component 60, the lifting member 50 is connected between the first driving component 40 and the lever lifting component 60, the lever lifting component 60 is connected to the cleaning mechanism 20, and the lever lifting component 60 can apply an external force to the cleaning mechanism 20 under the action of the lifting member 50 so that the cleaning mechanism 20 is in the first position, and the lever lifting component 60 can eliminate the external force applied to the cleaning mechanism 20 under the action of the lifting member 50 so that the cleaning mechanism 20 is in the second position under the action of the lifting member 50.

[0054] In the present embodiment, since the lifting member 50 is connected between the first driving assembly 40 and the lever lifting assembly 60, and the lever lifting assembly 60 is connected to the cleaning mechanism 20, when the cleaning device encounters an obstacle, the lifting member can be controlled by the first driving assembly 40, so that the lever lifting assembly 60 can apply an external force to the cleaning mechanism 20 under the action of the lifting member 50 to lift the cleaning mechanism 20 along the height direction of the fuselage 10 and be in the first position away from the surface to be cleaned, thereby preventing the cleaning mechanism 20 from colliding with the obstacle and causing the cleaning device to have difficulty in crossing the obstacle, facilitating the cleaning device to cross the obstacle and extending the service life of the cleaning mechanism 20; when the cleaning device needs to perform a cleaning operation, the lifting member 50 can be controlled by the first driving assembly 40. At this time, the lever lifting assembly 60 can eliminate the external force applied to the cleaning mechanism 20 under the action of the lifting member 50, and the cleaning mechanism 20 will descend along the height direction of the fuselage 10 under the action of gravity and be in the second position, so that the surface to be cleaned can be cleaned.

[0055] At the same time, since the present embodiment uses the lever lifting assembly 60 to apply external force to the cleaning mechanism 20 to achieve the lifting of the cleaning mechanism 20, in this process, the force amplification effect of the lever lifting assembly 60 is utilized, and only a small driving force is required to achieve the lifting of the cleaning mechanism 20, thereby saving energy consumption. Compared with the lifting of the cleaning mechanism 20 in the prior art, the lifting process of the cleaning mechanism 20 in the present embodiment is more labor-saving, so there is no need to use a high-power motor to provide sufficient pulling force for the cleaning mechanism 20, which reduces the overall weight of the cleaning device and reduces the manufacturing cost of the cleaning device.

[0056] The attached Figure 2Schematic diagram showing the structure of the lever lifting assembly 60 without lifting the cleaning mechanism 20; Figure 3 It shows a schematic structural diagram in which the lever lifting assembly 60 has lifted the cleaning mechanism 20 .

[0057] Furthermore, the lifting member 50 in this embodiment has a relaxed state and a tensioned state under the driving action of the first driving component 40; wherein, when the lifting member 50 is in the tensioned state, the lever lifting component 60 can apply an external force to the cleaning mechanism 20 to make the cleaning mechanism 20 in the first position; when the lifting member 50 is in the relaxed state, the lever lifting component 60 can eliminate the external force applied to the cleaning mechanism 20 and make the cleaning mechanism 20 in the second position under the action of gravity.

[0058] Specifically, in this embodiment, by switching the tension state and the relaxation state of the lifting member 50, the cleaning mechanism 20 can be driven to switch between the first position and the second position, thereby meeting the position requirements of the cleaning device under different working conditions. It is worth noting that "the lifting member 50 is in a tension state" in this embodiment means that the lifting member 50 is tightened under the pulling force of the first drive assembly 40, so that a rigid connection state is formed between the lifting member 50 and the first drive assembly 40; "the lifting member 50 is in a relaxation state" in this embodiment means that the first drive assembly 40 stops applying tension to the lifting member 50, so that the lifting member 50 picks up tension and is in a free or slightly relaxed state.

[0059] Further, see Figures 2 to 3 As shown, the lever lifting assembly 60 in this embodiment includes a lifting lever 61, which is rotatably arranged on the fuselage 10, one end of the lifting lever 61 is connected to the lifting member 50, and the other end of the lifting lever 61 is connected to the cleaning mechanism 20; wherein, when the lifting member 50 is in a taut state, the end of the lifting lever 61 connected to the lifting member 50 moves downward along the height direction of the fuselage 10 under the action of the lifting member 50, so that the end of the lifting lever 61 connected to the cleaning mechanism 20 moves upward along the height direction of the fuselage 10; when the lifting member 50 is in a relaxed state, the end of the lifting lever 61 connected to the cleaning mechanism 20 moves downward along the height direction of the fuselage 10 under the action of the cleaning mechanism 20, so that the end of the lifting lever 61 connected to the lifting member 50 moves upward along the height direction of the fuselage 10.

[0060] Specifically, in this embodiment, the rotatable characteristic of the lifting lever 61 is utilized to convert the movement of the lifting member 50 into the up and down movement of the cleaning mechanism 20. When the lifting member 50 is tightened and exerts downward force, the connection end of the lifting lever 61 and the lifting member 50 moves downward, and the connection end of the lifting lever 61 and the cleaning mechanism 20 moves upward through the lever principle, thereby realizing the lifting of the cleaning mechanism 20; conversely, when the lifting member 50 is relaxed, the gravity of the cleaning mechanism 20 causes the connection end of the lifting lever 61 and the cleaning mechanism 20 to move downward, thereby driving the connection end of the lifting lever 61 and the lifting member 50 to move upward, thereby realizing the lowering of the cleaning mechanism 20. It is worth noting that since the lifting lever 61 is used to lift the cleaning mechanism 20 in this embodiment, the lever arm length of the lifting lever 61 is reasonably designed based on the lever principle, so that a smaller force can be applied to the lifting member 50, thereby generating a larger lifting force at the connection end between the lifting lever 61 and the cleaning mechanism 20. In this way, a smaller power first drive component 40 can be used to drive the entire system, thereby reducing the requirements for the drive device and saving energy and costs.

[0061] At the same time, the rotational movement of the lifting lever 61 in this embodiment is relatively smooth. Driven by the lifting member 50, the rising and falling process of the cleaning mechanism 20 can be relatively gentle, reducing the impact and vibration during the movement, improving the overall stability of the cleaning device, and extending the service life of each component.

[0062] Further, see Figures 2 to 3 As shown, the lever lifting assembly 60 in this embodiment also includes a fixed shaft 62, which is arranged on the body 10, and the lifting lever 61 has a through hole 601. The lifting lever 61 is sleeved on the fixed shaft 62 through the through hole 601 and can rotate around the fixed shaft 62; the lifting lever 61 includes a bending section 611, a first straight section 612, a second straight section 613 and a third straight section 614, the bending section 611 is connected to the first straight section 612 through a connecting section 615, and the connecting section 615 has a through hole 601, the first straight section 612 and the third straight section 614 have the same extension direction, the second straight section 613 is connected between the first straight section 612 and the third straight section 614, the end of the bending section 611 away from the first straight section 612 is connected to the lifting member 50, and the end of the third straight section 614 away from the second straight section 613 is connected to the cleaning mechanism 20.

[0063] Specifically, the setting of the fixed shaft 62 provides a stable rotation support point for the lifting lever 61, ensuring that the lifting lever 61 can rotate stably around the fixed shaft 62, effectively ensuring the accuracy and reliability of the movement of the entire lever lifting assembly 60. The lifting lever 61 includes a bent section 611, a first straight section 612, a second straight section 613 and a third straight section 614. Such a setting can increase the structural strength of the lifting lever 61, so that the force from the lifting member 50 and the cleaning mechanism 20 can be dispersed to different parts of the lifting lever 61, avoiding the force concentration in a certain place causing excessive local stress and causing the lifting lever 61 to break.

[0064] Further, see Figure 3 As shown, in this embodiment, an inserting segment 616 is disposed on the third straight segment 614 , and the inserting segment 616 is protruded from the surface of the third straight segment 614 . An inserting groove 201 is disposed on the cleaning mechanism 20 , and the inserting segment 616 is located in the inserting groove 201 .

[0065] Specifically, the arrangement of the plug-in section 616 and the plug-in slot 201 realizes a direct connection between the third straight section 614 of the lifting lever 61 and the cleaning mechanism 20, and can effectively fix the two together, so that the lifting lever 61 can smoothly transmit force to the cleaning mechanism 20, thereby driving the cleaning mechanism 20 to perform a lifting movement, ensuring the stability and reliability of the force transmission path. At the same time, the arrangement of the plug-in section 616 and the plug-in slot 201 makes the installation and removal of the cleaning mechanism 20 more convenient and quick. During installation, it is only necessary to align the plug-in section 616 with the plug-in slot 201 and insert it to complete the connection; when the cleaning mechanism 20 needs to be repaired or replaced, it is only necessary to pull out the plug-in section 616, without the need to use complex tools or perform cumbersome operations, which greatly improves the maintenance convenience of the equipment and reduces maintenance costs and time.

[0066] Further, in order to improve the stability of the rotation of the lifting lever 61, see Figures 2 to 5As shown, the lever lifting assembly 60 in this embodiment further includes a guide component 63, which is connected between the lifting lever 61 and the lifting member 50, and includes a guide rod 631 and a slider 632. Specifically, the guide rod 631 is disposed on the fuselage 10 and extends along the height direction of the fuselage 10; the slider 632 has a guide hole 633, and the slider 632 is sleeved on the guide rod 631 through the guide hole 633 and can reciprocate along the length direction of the guide rod 631, and the slider 632 is connected between the lifting member 50 and the lifting lever 61; wherein, when the lifting member 50 is in a taut state, the slider 632 moves downward along the length direction of the guide rod 631 under the action of the lifting member 50 to drive the lifting lever 61 The end connected to the slider 632 moves downward synchronously, so that the end of the lifting lever 61 connected to the cleaning mechanism 20 moves upward along the height direction of the fuselage 10; when the lifting member 50 is in a relaxed state, the end of the lifting lever 61 connected to the cleaning mechanism 20 moves downward along the height direction of the fuselage 10 under the action of the cleaning mechanism 20, so that the end of the lifting lever 61 connected to the slider 632 moves upward along the height direction of the fuselage 10, and the slider 632 moves upward along the length direction of the guide rod 631.

[0067] Specifically, the setting of the guide rod 631 limits a unique path for the movement of the slider 632, so that the slider 632 can only reciprocate along the length direction of the guide rod 631, thereby ensuring the directional accuracy of the lifting member 50 and the lifting lever 61 connected to the slider 632 during the movement and avoiding arbitrary swinging or offset. As an intermediate component connecting the lifting member 50 and the lifting lever 61, the slider 632 can effectively transfer the force applied by the lifting member 50 to the lifting lever 61, and can also transfer the reaction force received by the lifting lever 61 to the lifting member 50, ensuring the smooth transmission of force between the two, so that the entire lever lifting assembly 60 can work normally. That is to say, through precise guidance and stable force transmission and balance in this embodiment, the operation of the entire lever lifting assembly 60 is more stable and reliable, reducing failures and abnormalities caused by unstable movement or uneven force, improving the overall stability and reliability of the cleaning device, and reducing the failure rate of the cleaning device.

[0068] Further, see Figure 2 as well as Figure 4 As shown, the lifting lever 61 in this embodiment is provided with a groove body 617, which extends along the length direction of the lifting lever 61 and is arranged through the thickness direction of the lifting lever 61; the slider 632 is provided with a rod body 634, the rod body 634 protrudes from the surface of the slider 632 and passes through the groove body 617, and the end of the rod body 634 away from the slider 632 has a stop block 635.

[0069] Specifically, the arrangement of the groove 617 and the rod 634 can realize the connection between the slider 632 and the lifting lever 61, so that the slider 632 and the lifting lever 61 can move in coordination, ensuring that under the action of the lifting member 50, the movement of the slider 632 can drive the corresponding end of the lifting lever 61 to move up and down. At the same time, since the groove 617 in this embodiment extends along the length direction of the lifting lever 61, and the rod 634 passes through the groove 617, when the lifting member 50 is in a taut state, the slider 632 will move downward along the guide rod 631 under the action of the lifting member 50. During this process, the rod 634 arranged on the slider 632 will move in the groove 617 along the extension direction of the groove 617, thereby ensuring that the connection end of the lifting lever 61 and the slider 632 can move downward smoothly, so that the connection end of the lifting lever 61 and the cleaning mechanism 20 moves upward to realize the lifting of the cleaning mechanism 20. In addition, in this embodiment, a stop block 635 is provided at the end of the rod body 634 away from the slider 632. In this way, the rod body 634 can be prevented from detaching from the groove body 617 during the movement of the slider 632, thereby effectively improving the stability and reliability of the connection between the slider 632 and the lifting lever 61.

[0070] Further, see Figures 4 to 5 As shown, in this embodiment, a limiting hole 636 is further provided on the slider 632, and the lifting member 50 includes a pull rope 51, one end of the pull rope 51 connected to the slider 632 is located in the limiting hole 636, and the maximum cross-sectional area of ​​the pull rope 51 is smaller than the minimum cross-sectional area of ​​the limiting hole 636. It should be noted that in this embodiment, the "cross-sectional area of ​​the pull rope 51" refers to the area of ​​the cross section obtained by cutting the pull rope 51 along a direction perpendicular to the length of the pull rope 51; the "cross-sectional area of ​​the limiting hole 636" refers to the area of ​​the cross section obtained by cutting the limiting hole 636 along a direction perpendicular to the extension direction of the limiting hole 636.

[0071] Specifically, the limiting hole 636 provides a limiting function for the pull rope 51, preventing the pull rope 51 from being separated from the slider 632 during operation, thereby ensuring the accuracy and stability of the pulling force transmission of the pull rope 51. At the same time, since the maximum cross-sectional area of ​​the pull rope 51 in this embodiment is smaller than the minimum cross-sectional area of ​​the limiting hole 636, such a configuration can, on the one hand, allow the pull rope 51 to have a certain amount of activity space in the limiting hole 636, preventing the pull rope 51 from being squeezed against the inner wall of the limiting hole 636 during operation and being worn, and on the other hand, can allow the pull rope 51 to be easily inserted into the limiting hole 636, thereby improving assembly efficiency.

[0072] Further, see Figure 4 as well as Figure 5As shown, the slider 632 in this embodiment is also provided with an avoidance notch 637, which is connected to the limiting hole 636 and extends along the height direction of the fuselage 10. The pull rope 51 is connected to one end of the slider 632 and has a stop protrusion 52. The pull rope 51 enters the limiting hole 636 from the avoidance notch 637 so that the stop protrusion 52 abuts against the slider 632, and the minimum cross-sectional area of ​​the stop protrusion 52 is greater than the maximum cross-sectional area of ​​the limiting hole 636.

[0073] Specifically, the setting of the avoidance notch 637 facilitates the installation of the pull rope 51, so that the pull rope 51 can smoothly enter the limiting hole 636 through the avoidance notch 637; the setting of the stop protrusion 52 can prevent the pull rope 51 from being separated from the limiting hole 636 during operation. In other words, when the pull rope 51 needs to be connected to the slider 632, it is only necessary to insert the pull rope 51 into the limiting hole 636 from the avoidance notch 637. At this time, since the minimum cross-sectional area of ​​the stop protrusion 52 is larger than the maximum cross-sectional area of ​​the limiting hole 636, the stop protrusion 52 will abut against the slider 632, making it difficult for the pull rope 51 to be separated from the limiting hole 636 when subjected to external force, effectively ensuring the stability and reliability of the connection between the lifting member 50 and the slider 632.

[0074] Further, see Figure 8 As shown, a rotatable roller 64 is disposed on the body 10 in this embodiment, and at least a portion of the lifting member 50 is wound around the roller 64 .

[0075] Specifically, the setting of the roller 64 can change the force direction of the lifting member 50. When the cleaning device is running, the rotation characteristics of the roller 64 can make the first drive component 40 more labor-saving when controlling the lifting member 50, reduce the power required by the first drive component 40, improve energy utilization efficiency, and reduce the energy consumption of the cleaning device.

[0076] Further, in order to ensure the stability of the lifting process of the cleaning mechanism 20, see Figure 2 , Figure 4 as well as Figure 8 As shown, the lifting levers 61 in this embodiment include two, the two lifting levers 61 are located at two opposite ends of the guide component 63 along the first direction and are respectively connected to the slider 632, and the two lifting levers 61 are both connected to the cleaning mechanism 20.

[0077] Specifically, the two lifting levers 61 are located at opposite ends of the guide member 63, which can make the cleaning mechanism 20 more balanced when subjected to force. When the slider 632 moves and drives the cleaning mechanism 20 through the lifting levers 61, the lifting levers 61 located at both ends of the guide member 63 can evenly share the weight of the cleaning mechanism 20 and various forces generated during the cleaning process, thereby preventing the cleaning mechanism 20 from tilting, shaking or even being damaged due to uneven force, and ensuring the stability and reliability of the cleaning mechanism 20 during operation.

[0078] Further, see Figure 7 As shown, the first driving assembly 40 in this embodiment includes a first gear box 41, a wire wheel 42 and a first driving member 43. The first gear box 41 is arranged on the fuselage 10, and the first gear box 41 includes a first box body 411 and a first gear set 412. The first gear set 412 is arranged in the first box body 411, and a first shell 413 is arranged on the first box body 411. The first shell 413 is surrounded to form an installation cavity, and an escape channel 414 is arranged on the side wall surface of the first shell 413; the wire wheel 42 is rotatably arranged in the installation cavity and connected to the first gear set 412 through a rotating shaft 415, and the end of the lifting member 50 away from the lever lifting assembly 60 is wound around the wire wheel 42, and the lifting member 50 passes through the escape channel 414; the first driving member 43 is arranged in the first box body 411 and is drivingly connected to the first gear set 412 to drive the first gear set 412 to rotate and drive the wire wheel 42 to rotate. Exemplarily, the first driving member 43 in this embodiment includes a driving motor.

[0079] Specifically, the first gear set 412 plays a key role in power transmission and conversion between the first driving member 43 and the wire wheel 42, so that the wire wheel 42 can generate sufficient pulling force to drive the lifting member 50, thereby realizing the lifting and lowering operation of the cleaning mechanism 20; the first box body 411 and the first shell body 413 provide a relatively closed space for the first gear set 412 and the wire wheel 42 respectively, and the first box body 411 encapsulates the first gear set 412 therein to prevent external dust, debris, etc. from entering the first box body 411, thereby avoiding the first gear set 412 The wear and failure between the gears 232 are reduced, and the service life of the first gear set 412 is extended. The installation cavity formed by the first shell 413 further protects the wire wheel 42, so that the wire wheel 42 is not interfered by external factors, and the normal rotation of the wire wheel 42 is ensured; the avoidance channel 414 on the side wall of the first shell 413 provides a fixed exit path for the pulling member 50, so that the pulling member 50 can be led out of the installation cavity in an orderly manner, avoiding the pulling member 50 from being entangled or interfering with other components during the movement, and ensuring the smooth movement of the pulling member 50.

[0080] That is to say, in this embodiment, when the cleaning device encounters an obstacle, the first driving member 43 controls the rotation of the wire wheel 42 through the first gear set 412, and the lifting member 50 is wound around the wire wheel 42 as the wire wheel 42 rotates and is in a tensioned state. At this time, the lifting member 50 applies a downward pulling force to the slider 632 in the guide member 63, so that the slider 632 moves downward along the length direction of the guide rod 631, thereby driving the connecting end of the lifting lever 61 and the slider 632 to move downward along with the slider 632, and then the connecting end of the lifting lever 61 and the cleaning mechanism 20 moves upward to realize the lifting of the cleaning mechanism 20.

[0081] Further, see Figure 6 As shown, the cleaning mechanism 20 in this embodiment includes a cleaning body 21, a bracket 22, a second driving assembly 23 and a guide assembly 24. The bracket 22 is connected to the body 10, the cleaning body 21 is connected to the bracket 22, and the cleaning body 21 has an extended position that moves with the bracket 22 to extend to the outer peripheral side of the body 10, and a retracted position that moves with the bracket 22 to retract to the inner side of the body 10. The second driving assembly 23 is connected to the bracket 22 to drive the cleaning body 21 to switch between the extended position and the retracted position, and the guide assembly 24 is connected between the body 10 and the bracket 22; wherein, at least one of the second driving assembly 23 and the guide assembly 24 is connected to the lever lifting assembly 60.

[0082] It is understandable that in this embodiment, the second drive assembly 23 can be connected to the lever lifting assembly 60, the guide assembly 24 can be connected to the lever lifting assembly 60, or both the second drive assembly 23 and the guide assembly 24 can be connected to the lever lifting assembly 60.

[0083] Specifically, when the cleaning device in this embodiment needs to be used to clean corners and other corners, it is only necessary to use the second driving component 23 to drive the bracket 22 to move, so as to drive the cleaning body 21 to move to the outward expansion position to clean corners and other corners, ensuring that the corner area is cleaned in place, and avoiding the phenomenon that there is a cleaning blind spot in the corner area after cleaning; and when there is no corner in the cleaned area, the second driving component 23 drives the bracket 22 to drive the cleaning body 21 to move to the retracted position, so that the cleaning body 21 can clean the cleaned area according to the predetermined cleaning route. The setting of the guide component 24 can improve the stability of the cleaning body 21 during the movement of the bracket 22.

[0084] Specifically, see Figure 6As shown, the second driving assembly 23 in this embodiment includes a second driving member 231, a gear 232 and a rack 233. The second driving member 231 is installed in the body 10 and is drivingly connected to the gear 232 to drive the gear 232 to rotate along its own circumferential direction. The rack 233 is installed on the bracket 22 and meshes with the gear 232. The rack 233 extends along the first direction, so that when the gear 232 and the rack 233 are meshed, the rack 233 can move a certain distance relative to the gear 232 along the first direction, thereby ensuring that the bracket 22 can drive the cleaning body 21 to move between the outward expansion position and the inward contraction position along the first direction. Exemplarily, the second driving member 231 in this embodiment includes a driving motor.

[0085] Specifically, in order to ensure the reliability of the meshing between the gear 232 and the rack 233, see Figure 6 As shown, the second drive assembly 23 also includes a second shell 234, which covers the gear 232. A cavity for the rack 233 to pass through is provided on the side of the second shell 234 close to the rack 233, and a plug-in slot 201 for the plug-in section 616 to be inserted is also provided on the second shell 234.

[0086] Specifically, see Figure 6 As shown, the guide assembly 24 in this embodiment includes a sliding block 241 and a guide rail 242. The sliding block 241 is disposed in the body 10, and the guide rail 242 is disposed on the bracket 22 and extends along the first direction. The guide rail 242 is connected to the sliding block 241 and can slide along the first direction with the bracket 22 relative to the sliding block 241. In this embodiment, the sliding cooperation between the sliding block 241 and the guide rail 242 is used to guide the cleaning body 21 to move smoothly along the first direction with the bracket 22. It is worth noting that the sliding block 241 in this embodiment is provided with an insertion groove 201 for the insertion section 616 to be inserted.

[0087] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0088] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
