[0017] In some embodiments, the locking mechanism further includes a first clutch and a second clutch; the first clutch is arranged on the lock sleeve; the second clutch is arranged on the adjustment member; the first clutch and the second clutch are configured to: limit the adjustment member from rotating relative to the lock sleeve when they are engaged with each other; and allow the adjustment member to rotate relative to the lock sleeve when they are disengaged from each other; wherein, when the first clutch and the second clutch are engaged with each other, the first gear is engaged with one of the multiple second gears.

[0018] In the above technical solution, the locking mechanism is further provided with a first clutch member and a second clutch member that can be engaged with or disengaged from each other, and the first clutch member and the second clutch member are respectively provided on the lock sleeve and the adjustment member, so that the adjustment member can be restricted from rotating relative to the lock sleeve by engaging with the first clutch member and the second clutch member, and the adjustment member can be allowed to rotate relative to the lock sleeve after the first clutch member and the second clutch member are disengaged from each other, so as to realize the function of the first clutch member and the second clutch member selectively locking the adjustment member and the lock sleeve, thereby alleviating the phenomenon of engagement failure between the locking member and the lock seat caused by erroneous rotation of the adjusting member, thereby improving the locking effect between the locking member and the lock seat, and helping to improve the stability and reliability of the mutual locking between the locking mechanism and the lock seat.

[0019] In some embodiments, the first clutch member and the second clutch member are arranged along the first direction; wherein, the first clutch member is fixed to the locking sleeve, and the second clutch member is fixed to the adjusting member, and the adjusting member is configured to drive the second clutch member to move along the first direction when moving along the first direction, so that the second clutch member can engage with or disengage from the first clutch member.

[0020] In the above technical solution, the first clutch member and the second clutch member are structures arranged along the first direction. By fixing the first clutch member on the lock sleeve and fixing the second clutch member on the adjustment member, the adjustment member can be moved along the first direction to drive the second clutch member to engage or disengage with the first clutch member, so as to limit the rotation of the adjustment member relative to the lock sleeve or allow the adjustment member to rotate relative to the lock sleeve. The structure is simple and easy to operate and implement.

[0022] In the above technical solution, the locking mechanism is also provided with an elastic member, and the elastic member is arranged between the locking sleeve and the adjusting member. The elastic member can apply a force to the adjusting member in the first direction to drive the second clutch member to move in the direction close to the first clutch member, so that the first clutch member and the second clutch member are engaged with each other, so that the adjusting member can be automatically reset in the first direction to the position where the first clutch member and the second clutch member are engaged with each other through the elastic member. The locking mechanism with such a structure can, on the one hand, further improve the stability of the mutual engagement of the first clutch member and the second clutch member to reduce the phenomenon of accidental disengagement of the first clutch member and the second clutch member. On the other hand, after the second clutch member and the first clutch member are disengaged from each other, the elastic member can drive the adjusting member to move along the first direction and realize automatic engagement of the second clutch member and the first clutch member, without manual intervention, which is easy to operate and use.

[0023] In some embodiments, the adjusting member includes a guide section, a first assembly section and a second assembly section connected in sequence, and along the first direction, the guide section and the second assembly section are respectively protruded from the two ends of the first assembly section; wherein, the first gear is fixedly sleeved on the outside of the first assembly section, the second clutch member is fixedly sleeved on the outside of the second assembly section, the elastic member is sleeved on the guide section, and the two ends of the elastic member in the first direction are respectively abutted against the locking sleeve and the first assembly section.

[0024] In the above technical solution, the adjusting member is provided with a guide section, a first assembly section and a second assembly section, and the guide section and the second assembly section are respectively protruded from the two ends of the first assembly section in the first direction. By fixing the first gear and the second clutch member on the outer sides of the first assembly section and the second assembly section respectively, and sleeved the elastic member on the outer side of the guide section, the two ends of the elastic member can respectively abut against the locking sleeve and the first assembly section. The locking mechanism with such a structure can, on the one hand, reduce the interference between the first gear, the second clutch member and the elastic member, facilitate assembly, and facilitate the elastic member to apply elastic force to the adjusting member, so that the elastic member drives the adjusting member to move along the first direction toward the second clutch member close to the first clutch member. On the other hand, the guide section can play a certain guiding role on the elastic member, so as to realize the stable compression of the elastic member along the first direction, which is conducive to alleviating the radial deformation or bending of the elastic member, thereby improving the stability and reliability of the elastic member.

[0025] In some embodiments, along the first direction, a first tooth-shaped portion is provided at one end of the first clutch member facing the second clutch member, and a second tooth-shaped portion is provided at one end of the second clutch member facing the first clutch member. The second tooth-shaped portion is used to engage with the first tooth-shaped portion to achieve a snap-fit ​​fit between the second clutch member and the first clutch member.

[0026] In the above technical solution, a first toothed portion is provided on one end of the first clutch member facing the second clutch member, and a second toothed portion is correspondingly provided on one end of the second clutch member facing the first clutch member. This allows the second toothed portion to engage or disengage with the first toothed portion when the adjusting member drives the second clutch member to move in the first direction, thereby achieving a snap-fit ​​or disengagement between the second clutch member and the first clutch member. This allows the first and second clutch members to cooperate in limiting the rotation of the adjusting member relative to the locking sleeve when the first and second toothed portions are engaged with each other. This structure is simple and easy to implement. In addition, the provision of the first and second toothed portions on the first and second clutch members facilitates the snap-fit ​​or disengagement between the first and second clutch members, thereby reducing the difficulty of the first and second clutch members engaging or disengaging with each other.

[0028] In the above technical solution, the locking member is provided with a connecting portion and a clamping portion connected to one end of the connecting portion, and the clamping portion protrudes from the outer peripheral surface of the connecting portion in its extension direction. By inserting the connecting portion into the lock sleeve along the first direction and connecting it to the second gear, the adjusting member can drive the corresponding second gear to rotate when the first gear and the second gear are engaged, so as to drive the connecting portion of the corresponding locking member to rotate relative to the lock sleeve, so that the clamping portion can rotate with the connecting portion, thereby realizing that the extension direction of the clamping portion changes in a plane perpendicular to the first direction, so that the clamping portion can be engaged with or disengaged from the lock seat after rotation, thereby realizing that the locking member of the locking mechanism can engage with or disengage from the lock seat in the first direction.

The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping part cannot be clamped with the lock seat due to the large angle of rotation of the clamping part following the connecting part, which is beneficial to improving the reliability of the mutual locking between the locking mechanism and the lock seat.

[0031] In some embodiments, the connecting portion is threadedly connected to the second gear, and the first limiting portion and the second limiting portion are also configured to cooperate to guide the connecting portion to move along the first direction when the second gear drives the corresponding locking member to rotate, so that the locking member moves between the first position and the second position along the first direction; when the locking member is in the first position, the locking member is in a locked state, so that the clamping portion can be clamped with the lock seat; when the locking member is in the second position, the locking member is in an unlocked state, so that the clamping portion can be released from the lock seat.

[0032] In the above technical solution, by setting the connecting part and the second gear to a structure in which the connecting part is threadedly connected to each other, the locking mechanism using this structure enables the second gear to apply a feed force to the connecting part moving along the first direction when the rotation of the connecting part is restricted, so that the first limiting part and the second limiting part can cooperate to guide the connecting part to move relative to the locking sleeve in the first direction while realizing limiting the rotation angle of the connecting part, so that the adjusting part can drive the connecting part to rotate relative to the locking sleeve through the first gear and the second gear, and can also drive the locking part to move between the first position and the second position along the first direction, so that the adjusting part can drive the clamping part to clamp with the lock seat, and can also drive the clamping part and the lock seat to abut against each other, so as to reduce the size of the gap between the clamping part and the lock seat, which is beneficial to reduce vibration or impact between the locking mechanism and the lock seat.

[0034] In the above technical solution, the first limiting portion and the second limiting portion are respectively a limiting groove arranged on the inner circumferential surface of the locking sleeve and a limiting protrusion on the outer circumferential surface of the connecting portion. By inserting the limiting protrusion into the limiting groove, the rotation angle of the connecting portion can be limited under the restriction of the limiting groove, and the limiting protrusion can realize the rotation of the connecting portion relative to the locking sleeve under the guidance of the limiting groove while also being able to move relative to the locking sleeve along the first direction. The structure is simple, easy to implement, and has high stability.

[0036] In the above technical solution, by configuring the first and third groove sections of the limiting groove to extend in the first direction, and the first and third groove sections to be spaced apart in the first direction and in the circumferential direction of the connecting portion, and configuring the second groove section connected between the first and third groove sections to be a spirally extending structure, the limiting protrusion of the connecting portion can only move in the first direction following the extension direction of the first and second groove sections when located in the first and third groove sections, and the protrusion of the connecting portion can rotate relative to the lock sleeve following the extension direction of the second groove section while also being able to move relative to the lock sleeve in the first direction when located in the second groove section, thereby achieving the limitation of the rotation angle of the locking member and enabling movement between the first position and the second position in the first direction. In addition, by configuring the third groove section to be closer to the engaging portion than the first groove section in the first direction, the engaging portion can engage with the lock seat and be closer to the lock sleeve when the protrusion is located in the first groove section, so that the engaging portion and the lock seat can abut against each other in the first direction.

[0037] In some embodiments, the adjusting member is configured to simultaneously drive the plurality of locking members to move relative to the locking sleeve, so that the plurality of locking members can be switched between the locked state and the unlocked state at the same time.

[0059] In some embodiments, the locking member includes a connecting portion and a clamping portion; the connecting portion extends along a first direction and is inserted into the lock sleeve, and the connecting portion is rotatably connected to the moving member around an axis extending along the first direction; the clamping portion is located outside the lock sleeve and is connected to an end of the connecting portion away from the lock sleeve, and the clamping portion protrudes from the outer peripheral surface of the connecting portion along its extension direction, and the clamping portion is used to clamp with the lock seat, and the extension direction of the clamping portion is perpendicular to the first direction; wherein the moving member is configured to be able to simultaneously drive the connecting portions of multiple locking members to rotate when it moves relative to the lock sleeve along the first direction, so that the clamping portions of multiple locking members are all clamped or released with the lock seat, so that multiple locking members can switch between the locked state and the unlocked state at the same time.

[0060] In the above technical solution, the locking member is provided with a connecting portion and a clamping portion connected to one end of the connecting portion, and the clamping portion protrudes from the outer peripheral surface of the connecting portion in its extension direction. By inserting the connecting portion into the lock sleeve along a first direction and rotatably connected to the movable member around an axis extending along the first direction, the adjusting member can drive the movable member to move along the first direction when rotating relative to the lock sleeve, so as to simultaneously drive the connecting portions of multiple locking members to rotate relative to the lock sleeve, so that the corresponding clamping portions can follow the corresponding connecting portions to rotate, thereby realizing that the extension direction of the clamping portion is changed in a plane perpendicular to the first direction, so that the clamping portions of multiple locking members can be simultaneously engaged or disengaged with the lock seat after rotation, thereby realizing that multiple locking members of the locking mechanism can engage with or disengage from the lock seat in the first direction.

[0061] In some embodiments, the connecting portion and the moving member are axially locked along a first direction; wherein, the locking sleeve is provided with a first limiting portion, and the connecting portion is provided with a second limiting portion, and the first limiting portion and the second limiting portion are configured to cooperate to guide the connecting portion to rotate around an axis extending along the first direction when the moving member drives the locking member to move between the first position and the second position along the first direction; when the locking member is in the first position, the locking member is in a locked state, so that the clamping portion can be clamped with the lock seat; when the locking member is in the second position, the locking member is in an unlocked state, so that the clamping portion can be released from the lock seat.

[0062] In the above technical solution, the connecting portion of the locking member and the moving member are structures that are axially locked in the first direction, so that when the adjusting member drives the moving member to move along the first direction, the moving member can drive the connecting portion to move along the first direction, and the connecting portion can rotate relative to the moving member, so that the first limiting portion and the second limiting portion are respectively provided on the lock sleeve and the connecting portion, so that when the moving member drives the connecting portion to move along the first direction, the first limiting portion and the second limiting portion can also cooperate to guide the connecting portion to rotate relative to the moving member, so that the adjusting member can drive the locking member's clamping portion to engage with the lock seat through the moving member, and can also drive the clamping portion and the lock seat to abut against each other, so as to reduce the size of the gap between the clamping portion and the lock seat, which is beneficial to reduce vibration or impact between the locking mechanism and the lock seat.

[0063] In some embodiments, the first limiting portion is a limiting protrusion protruding from the inner circumference of the locking sleeve, and the second limiting portion is a limiting groove provided on the outer circumference of the connecting portion, with at least a portion of the limiting protrusion being accommodated in the limiting groove.

[0064] In the above technical solution, the first limiting portion and the second limiting portion are respectively a limiting protrusion arranged on the inner circumferential surface of the locking sleeve and a limiting groove on the outer circumferential surface of the connecting portion. By inserting the limiting protrusion into the limiting groove, the connecting portion can be guided by the cooperation of the limiting groove and the limiting protrusion to realize that the connecting portion can move along the first direction relative to the locking sleeve and can also rotate relative to the locking sleeve, so that the rotation angle of the connecting portion can be limited under the restriction of the limiting groove, and the limiting protrusion can be guided by the limiting groove to realize that the connecting portion can move along the first direction relative to the locking sleeve and can rotate relative to the locking sleeve. The structure is simple, easy to implement, and has high stability.

[0065] In some embodiments, the limiting groove includes a first groove section, a second groove section and a third groove section connected in sequence, the first groove section and the third groove section both extend along the first direction, the first groove section and the third groove section are arranged at intervals along the circumference of the connecting portion, and the first groove section and the third groove section are arranged at intervals along the first direction, along the first direction, the third groove section is closer to the clamping portion than the first groove section; when the locking member is in the first position, the limiting protrusion is located in the third groove section, and when the locking member is in the second position, the limiting protrusion is located in the first groove section.

[0066] In the above technical solution, the first groove section and the third groove section of the limiting groove are set to structures that extend along the first direction, and the first groove section and the third groove section are arranged at intervals in the first direction and the circumferential direction of the connecting part, so that the second groove section connected between the first groove section and the third groove section is a spirally extended structure, so that when the limiting protrusion of the locking sleeve is located in the first groove section and the third groove section, the connecting part can only move along the first direction under the cooperation of the limiting protrusion and the first groove section or the limiting protrusion and the third groove section, and when the limiting protrusion of the locking sleeve is located in the second groove section, the connecting part can move relative to the locking sleeve along the first direction and rotate relative to the locking sleeve under the cooperation of the limiting protrusion and the second groove section, so that the connecting part can move relative to the locking sleeve along the first direction and can also rotate relative to the locking sleeve, thereby realizing that the locking member can move between the first position and the second position along the first direction and can also rotate relative to the locking sleeve between the locked state and the unlocked state. In addition, by setting the third groove section to be closer to the clamping portion than the first groove section in the first direction, when the protrusion is located in the third groove section, the clamping portion can be clamped with the lock seat and can be closer to the lock sleeve, so that the clamping portion and the lock seat can abut against each other in the first direction.

[0067] In some embodiments, the adjusting member is rotatably disposed on the locking sleeve around an axis extending along the first direction. The adjusting member is configured to drive multiple locking members to move relative to the locking sleeve when rotating relative to the locking sleeve, so that the locking members can switch between a locked state and an unlocked state.

[0068] In the above technical solution, the adjusting member is rotatably arranged in the lock sleeve around an axis extending in the first direction. By rotating the adjusting member, the locking member can be driven to move relative to the lock sleeve, so that the locking member can be engaged or disengaged with the lock seat. The locking mechanism with this structure is convenient for subsequent operation. The locking mechanism and the lock seat can be locked or unlocked by simply rotating the adjusting member, which is beneficial to improving the operating efficiency and convenience of the locking mechanism.

[0069] In some embodiments, the locking member includes a connecting portion and a clamping portion; the connecting portion extends along a first direction and is inserted into the lock sleeve, and the connecting portion is transmission-connected to the adjusting member; the clamping portion is located outside the lock sleeve and is connected to an end of the connecting portion away from the lock sleeve, and the clamping portion protrudes from the outer peripheral surface of the connecting portion along its extension direction, and the clamping portion is used to clamp with the lock seat, and the extension direction of the clamping portion is perpendicular to the first direction; wherein the adjusting member is configured to drive the connecting portion to rotate when it rotates relative to the lock sleeve, so that the clamping portion is clamped or released with the lock seat, so that the locking member can switch between a locked state and an unlocked state.

[0070] In the above technical solution, the locking member is provided with a connecting portion and a clamping portion connected to one end of the connecting portion, and the clamping portion protrudes from the outer peripheral surface of the connecting portion in its extension direction. By inserting the connecting portion into the lock sleeve along the first direction and connecting it to the adjusting member in a transmission connection, the adjusting member can drive the connecting portion to rotate when it rotates, so that the clamping portion can rotate with the connecting portion, thereby realizing that the extension direction of the clamping portion is changed in a plane perpendicular to the first direction, so that the clamping portion can be engaged with or disengaged from the lock seat after rotation, thereby realizing that the locking mechanism can engage with or disengage from the lock seat in the first direction.

[0071] In some embodiments, the clamping portion and the locking sleeve are arranged along a first direction, and the locking sleeve has a clamping surface facing the clamping portion in the first direction. The clamping surface and the clamping portion are configured to respectively abut against both sides of the lock seat along the first direction when the locking member is in a locked state.

[0072] In the above technical solution, the locking sleeve has a clamping surface facing the clamping portion in the first direction, and the clamping surface and the clamping portion of the locking member can respectively abut against the two sides of the lock seat along the first direction when the locking member is in a locked state, so that the locking mechanism can clamp the lock seat in the first direction through the clamping portion of the locking member and the clamping surface of the locking sleeve, which is beneficial to reduce the shaking phenomenon of the locking mechanism during use, so as to improve the stability and reliability of the mutual locking between the locking mechanism and the lock seat.

[0073] In some embodiments, the clamping portion and the connecting portion are integrally formed.

[0074] In the above technical solution, by setting the connecting part and the clamping part of the locking member as an integrally formed structure, the connection stability and structural strength between the connecting part and the clamping part can be improved, which is beneficial to reduce the risk of connection failure or falling off between the connecting part and the clamping part, thereby improving the service life of the locking member and improving the stability and reliability of the locking mechanism locked on the lock seat.

[0075] In some embodiments, the clamping portion and the connecting portion are separately provided, and the clamping portion is detachably connected to the connecting portion.

[0076] In the above technical solution, by setting the clamping portion of the locking piece to a structure that is detachably connected to the connecting part, the locking piece can be assembled by inserting the end of the connecting piece provided with the clamping portion into the lock sleeve, that is, the connecting piece is first inserted into the lock sleeve, and then the clamping portion is assembled on the connecting piece. The locking mechanism adopting this structure can, on the one hand, reduce the difficulty of assembling the locking piece and the lock sleeve, and on the other hand, it is only necessary to set the aperture of the assembly hole for the connecting piece to pass through the end of the lock sleeve close to the clamping portion in the first direction to match the diameter of the connecting piece, thereby reducing the assembly gap between the connecting piece of the locking piece and the lock sleeve, alleviating the shaking phenomenon of the locking mechanism during use, and reducing the risk of impurities entering the lock sleeve through the gap between the connecting piece of the locking piece and the lock sleeve, thereby effectively improving the service life and reliability of the locking mechanism. In addition, since the locking part of the locking member needs to be engaged with the lock seat, when the locking part is deformed or damaged, only the locking part needs to be replaced, and there is no need to replace the entire locking member, which is beneficial to reducing the later maintenance cost of the locking mechanism.

[0077] In some embodiments, the clamping portion is screwed to the connecting portion.

[0078] In the above technical solution, the clamping part is set as a structure that is screwed onto the connecting part, so that the clamping part and the connecting part are threadedly connected structures to achieve a detachable connection between the clamping part and the connecting part. The locking part with such a structure is conducive to reducing the difficulty of assembly between the clamping part and the connecting part, and can improve the structural stability and reliability of the clamping part connected to the connecting part.

[0079] In a second aspect, an embodiment of the present application further provides a battery component, comprising a battery and the above-mentioned locking mechanism; the battery comprises a box body, and the lock sleeve is installed on the box body.

[0080] In the above technical solution, by installing the locking mechanism on the battery box, the battery can be locked or unlocked with the lock seat through the locking mechanism to realize the battery replacement function, and the locking mechanism of this structure can improve the battery replacement efficiency.

[0081] In a third aspect, an embodiment of the present application further provides a battery pack comprising a plurality of batteries and the above-mentioned locking mechanism; the battery comprises a box body, and the locking sleeves are respectively connected to the boxes of the plurality of batteries.

[0082] In the above technical solution, the battery pack is provided with multiple batteries, and the locking sleeve of the locking mechanism is connected to the boxes of the multiple batteries, so that the multiple locking parts of the locking mechanism can lock the multiple batteries respectively. It is only necessary to operate an adjustment part of the locking mechanism to lock or unlock the multiple batteries and the lock seat, and the multiple batteries and the locking mechanism can be assembled into a whole before the battery is replaced. On the one hand, it can optimize the operating space reserved for the locking mechanism between the multiple batteries to further increase the tightness of the mutual assembly between the multiple batteries, which is beneficial to improving the space utilization of the battery. On the other hand, there is no need to lock or unlock the multiple batteries multiple times, so as to reduce the locking or unlocking actions required for the multiple batteries during the battery replacement process, which is beneficial to optimizing the battery replacement rhythm of the multiple batteries, thereby improving the battery replacement efficiency and saving the battery replacement cost.

DETAILED DESCRIPTION

[0110] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0111] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0112] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0113] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0114] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0115] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0116] The term "plurality" used in this application refers to two or more (including two).

[0117] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0118] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0119] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, placed between the positive and negative electrodes, prevents short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0120] In some embodiments, the positive electrode may be a positive electrode sheet, and the negative electrode may be a negative electrode sheet.

[0121] In some embodiments, the electrode assembly further includes a separator disposed between the positive electrode and the negative electrode.

[0122] In some embodiments, the separator is a separator.

[0123] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0124] As an example, the battery cells may be cylindrical, prismatic, soft-pack or other shaped battery cells. Prismatic battery cells include but are not limited to square-shell, blade-shaped, and polygonal batteries, such as hexagonal batteries.

[0125] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0126] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0127] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0128] With technological advancements and the rapid development of new energy vehicles, electric vehicles are gaining increasing market share and frequency of use. Electric commercial vehicles, such as heavy-duty and light-duty electric trucks, are gradually appearing in various application scenarios, and battery swap stations have been built to accommodate these vehicles.

[0129] In the field of new energy vehicles, electric trucks consume more energy than ordinary passenger cars due to their heavy loads and long driving range. Therefore, to achieve endurance, electric trucks are usually equipped with multiple or larger batteries. Electric trucks also need to frequently swap batteries. During the battery swap process, the locking, fixation, and separation of the battery on the vehicle are key issues. To achieve this, the main method currently used is to install a lock seat on the vehicle and a corresponding locking mechanism on the battery. The locking mechanism and the lock seat are used to lock or unlock the battery to complete the vehicle's battery swap function. However, since multiple batteries are independent individuals or larger batteries require multiple locking mechanisms to fix them, when replacing multiple batteries or larger batteries, on the one hand, multiple locking mechanisms need to be locked or unlocked individually to achieve battery replacement of multiple batteries or larger batteries, resulting in more locking or unlocking actions required for the electrical equipment, making the battery replacement process of the electrical equipment more cumbersome, which is not conducive to improving the battery replacement efficiency. On the other hand, since there is a sequence in the replacement assembly of multiple batteries, it is necessary to set reserved space between the multiple batteries to alleviate assembly interference, resulting in poor assembly tightness between the multiple batteries and more space occupied by multiple batteries, which is not conducive to improving the space utilization of multiple batteries assembled on the vehicle.

[0130] Based on the above considerations, in order to solve the problem of low battery replacement efficiency, an embodiment of the present application provides a locking mechanism for engaging or disengaging with a lock seat along a first direction, and the locking mechanism includes a lock sleeve, an adjustment member and a plurality of locking members. The plurality of locking members can be movably arranged on the lock sleeve, and the locking member has a locked state and an unlocked state. The locking member is configured to engage with the lock seat when in the locked state so that the locking mechanism and the lock seat are engaged along the first direction, and the locking member is configured to release the engagement with the lock seat when in the unlocked state so as to allow the locking mechanism and the lock seat to disengage along the first direction. The adjustment member is provided on the lock sleeve, and the adjustment member is configured to be able to drive the plurality of locking members to move relative to the lock sleeve so that the locking member switches between the locked state and the unlocked state.

[0131] In the locking mechanism of this structure, the locking mechanism is provided with multiple locking members, and through an adjusting member, the multiple locking members can be driven to move relative to the locking sleeve to realize locking or unlocking of the locking member and the lock seat. The locking mechanism adopting this structure can, on the one hand, lock or unlock through multiple locking members and the lock seat, which can effectively improve the load-bearing capacity and locking capacity of the locking mechanism, thereby helping to reduce the risk of breakage or accidental disengagement of the locking mechanism during use, so as to improve the service life and reliability of the locking mechanism. On the other hand, only one adjusting member needs to be operated to complete the locking or unlocking of multiple locking members and the lock seat. There is no need to set an adjusting member for each locking member, and there is no need to switch different adjusting members for operation when driving different locking members, thereby reducing the locking or unlocking actions required by the locking mechanism during use, which is beneficial to improving the operating efficiency of the locking mechanism and reducing the use cost of the locking mechanism. In addition, when a locking mechanism of this structure is applied to a battery replacement scenario of multiple batteries, the locking sleeve of the locking mechanism can be connected to multiple batteries, and multiple locking parts can be used to lock multiple batteries respectively, so that multiple batteries can be locked or unlocked by operating an adjustment part of a locking mechanism, and multiple batteries and the locking mechanism can be assembled into a whole before battery replacement, thereby optimizing the operating space reserved for the locking mechanism between multiple batteries, so as to further increase the tightness of the mutual assembly between multiple batteries, which is beneficial to improving the space utilization of the battery and the battery replacement efficiency.

[0132] The locking mechanism disclosed in the embodiments of the present application can be used, but is not limited to, in electrical equipment such as vehicles, ships, or aircraft. The power supply system of the electrical equipment can be composed of a battery component or battery pack disclosed in the present application, which helps alleviate the problem of low battery replacement efficiency in the electrical equipment.

[0142] Among them, the box body 11 is used to provide an assembly space for the battery cell 12, and the box body 11 can adopt a variety of structures. In some embodiments, the box body 11 may include a first box body 111 and a second box body 112, and the first box body 111 and the second box body 112 cover each other, and the first box body 111 and the second box body 112 jointly define an assembly space for accommodating the battery cell 12. The first box body 111 and the second box body 112 can be hollow structures with one side open, and the open side of the first box body 111 covers the open side of the second box body 112, so that the first box body 111 and the second box body 112 jointly define an assembly space. Exemplarily, the locking mechanism 20 can be connected to the first box body 111 or to the second box body 112.

[0143] In other embodiments, the box body 11 may also have other structures. For example, the second box body 112 may be a hollow structure with one end open, and the first box body 111 may be a plate-like structure. The first box body 111 covers the open side of the second box body 112, so that the first box body 111 and the second box body 112 jointly define an assembly space. Of course, the box body 11 formed by the first box body 111 and the second box body 112 may have various shapes, such as a cylinder, a rectangular parallelepiped, etc. For example, in FIG6 , the box body 11 is in the shape of a rectangular parallelepiped.

[0144] In the battery 10, the number of battery cells 12 disposed in the housing 11 may be one or more. When there are multiple battery cells 12 disposed in the housing 11, the multiple battery cells 12 may be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 12 are connected in series and in parallel. The multiple battery cells 12 may be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 12 may be accommodated in the housing 11. Of course, the battery 10 may also be a battery module formed by first connecting multiple battery cells 12 in series, in parallel, or in mixed connection, and then the multiple battery modules may be connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the housing 11. In some embodiments, the battery 10 may further include other structures. For example, the battery 10 may further include a busbar component, which is used to connect the multiple battery cells 12 to achieve electrical connection between the multiple battery cells 12.

[0145] Each battery cell 12 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 12 can be cylindrical, flat, rectangular, or in other shapes. For example, in FIG6 , the battery cell 12 is a rectangular parallelepiped.

[0146] According to some embodiments of the present application, referring to Figures 3, 4, and 5, and further referring to Figures 7, 8, and 9, Figure 7 is a schematic structural diagram of a locking mechanism 20 provided in some embodiments of the present application, Figure 8 is an exploded structural diagram of a locking mechanism 20 provided in some embodiments of the present application, and Figure 9 is a cross-sectional view of a locking mechanism 20 provided in some embodiments of the present application. The present application provides a locking mechanism 20 for engaging or disengaging with a lock base 300 along a first direction X to achieve locking or unlocking of a target part with the lock base 300. The locking mechanism 20 includes a lock sleeve 21, an adjustment member 22, and a plurality of locking members 23. A plurality of locking members 23 are movably disposed on the lock sleeve 21 . The locking members 23 have a locked state and an unlocked state. When in the locked state, the locking members 23 are configured to engage with the lock base 300 , so that the locking mechanism 20 and the lock base 300 engage along the first direction X. When in the unlocked state, the locking members 23 are configured to disengage from the lock base 300 , so that the locking mechanism 20 and the lock base 300 disengage along the first direction X. An adjustment member 22 is disposed on the lock sleeve 21 . The adjustment member 22 is configured to drive the plurality of locking members 23 to move relative to the lock sleeve 21 , so that the locking members 23 switch between the locked state and the unlocked state.

[0147] The locking sleeve 21 is connected to the target part and serves to assemble the locking member 23 and the adjusting member 22, so that the locking mechanism 20 can lock the target part to the lock base 300 through the locking member 23. The locking sleeve 21 is a hollow structure to assemble the locking member 23 and the adjusting member 22, and is provided with an assembly hole 211 for the locking member 23 to extend out of the locking sleeve 21, and a through hole 212 for the adjusting member 22 to extend out of the locking sleeve 21.

[0148] Exemplarily, the lock sleeve 21 can be made of various materials, such as steel, aluminum, iron, aluminum alloy or plastic.

[0149] The locking member 23 is used to engage or disengage with the lock base 300 so that the locking mechanism 20 can engage or disengage with the lock base 300 along the first direction X through the locking member 23 to achieve locking or unlocking between the locking mechanism 20 and the lock base 300.

[0150] The locking member 23 is movable relative to the lock sleeve 21 , so that the locking member 23 has a locked state in which it can be engaged with the lock base 300 and an unlocked state in which it can be released from the lock base 300 . For example, in Figures 8 and 9, the locking member 23 includes a connecting portion 231 and a clamping portion 232 that are interconnected. The connecting portion 231 is a columnar structure extending along the first direction X and is inserted into the lock sleeve 21 along the first direction X. The connecting portion 231 is transmission-connected to the adjusting member 22. The clamping portion 232 is connected to one end of the connecting portion 231 extending out of the lock sleeve 21 in the first direction X, and the clamping portion 232 plays a role of mutual clamping with the lock seat 300. The extension direction of the clamping portion 232 is perpendicular to the first direction X, so that the locking member 23 is an irregular structure that can be rotated around an axis extending in the first direction X, so that the clamping portion 232 can be driven to rotate by rotating the connecting portion 231, so that the clamping portion 232 can be clamped or released from the lock seat 300. Of course, in other embodiments, the engaging portion 232 of the locking member 23 may also be a retractable structure in a direction perpendicular to the first direction X, so that the locking member 23 can be engaged with or disengaged from the lock base 300 through the engaging portion 232 .

[0151] The adjusting member 22 is configured to drive the plurality of locking members 23 to move relative to the lock sleeve 21, so that the locking members 23 switch between the locked state and the unlocked state. In other words, the adjusting member 22 can drive the plurality of locking members 23 to move relative to the lock sleeve 21, so that the locking members 23 can switch between the locked state and the unlocked state. For example, in Figures 8 and 9, the adjusting member 22 can drive the connecting portion 231 of the locking member 23 to rotate relative to the lock sleeve 21, so that the connecting portion 231 drives the engaging portion 232 to rotate, thereby enabling the engaging portion 232, whose extending direction is perpendicular to the first direction X, to rotate within a plane perpendicular to the first direction X, thereby enabling the engaging portion 232 to engage or disengage with the lock seat 300, so that the locking member 23 can switch between the locked state and the unlocked state. It should be noted that the adjusting member 22 is configured to be able to drive multiple locking members 23 to move relative to the locking sleeve 21. The adjusting member 22 can be capable of individually driving each locking member 23 to move relative to the locking sleeve 21, that is, the adjusting member 22 can individually drive each locking member 23 to switch between the locked state and the unlocked state in sequence. The adjusting member 22 can also be capable of simultaneously driving multiple locking members 23 to move relative to the locking sleeve 21, that is, the adjusting member 22 can simultaneously drive multiple locking members 23 to switch between the locked state and the unlocked state.

[0152] For example, in Figures 8 and 9, the locking mechanism 20 is further provided with a transmission assembly 24, so that the adjusting member 22 is a structure that is transmission-connected to the locking member 23 through the transmission assembly 24, so that the adjusting member 22 can individually drive each locking member 23 to move relative to the locking sleeve 21 or simultaneously drive multiple locking members 23 to move relative to the locking sleeve 21, so that the adjusting member 22 and the locking member 23 are indirectly connected through the transmission assembly 24. Of course, in other embodiments, the adjusting member 22 can also be a structure that is directly connected to the locking member 23.

[0153] For example, in Figures 8 and 9, the locking mechanism 20 includes two locking members 23, both of which are movably disposed on the lock sleeve 21. The adjustment member 22 is used to drive the two locking members 23 to move relative to the lock sleeve 21, so that the two locking members 23 can be switched between a locked state and an unlocked state. Of course, in other embodiments, the locking mechanism 20 can also be provided with three, four, or five locking members 23.

[0154] In this embodiment, the locking mechanism 20 is provided with a plurality of locking members 23, and through a single adjusting member 22, the plurality of locking members 23 can be driven to move relative to the lock sleeve 21 to achieve locking or unlocking of the locking members 23 and the lock seat 300. The locking mechanism 20 adopting such a structure can, on the one hand, lock or unlock the locking members 23 and the lock seat 300 by using the plurality of locking members 23, which can effectively improve the load-bearing capacity and locking capacity of the locking mechanism 20, thereby helping to reduce the risk of breakage or accidental disengagement of the locking mechanism 20 during use, thereby improving the service life and reliability of the locking mechanism 20. On the other hand, only one adjusting member 22 needs to be operated to complete the locking or unlocking of the plurality of locking members 23 and the lock seat 300. There is no need to provide a corresponding adjusting member 22 for each locking member 23, and there is no need to switch different adjusting members 22 for operation when driving different locking members 23. Therefore, the locking or unlocking actions required by the locking mechanism 20 during use can be reduced, which is conducive to improving the operating efficiency of the locking mechanism 20 and reducing the use cost of the locking mechanism 20. In addition, when the locking mechanism 20 of this structure is applied to the battery replacement scenario of multiple batteries 10, the locking sleeve 21 of the locking mechanism 20 can be connected to the multiple batteries 10, and the multiple locking parts 23 can be respectively locked to the multiple batteries 10, so that the multiple batteries 10 can be locked or unlocked by operating an adjustment part 22 of a locking mechanism 20, and the multiple batteries 10 and the locking mechanism 20 can be assembled into a whole before the battery replacement, thereby optimizing the operating space reserved for the locking mechanism 20 between the multiple batteries 10, so as to further increase the tightness of the mutual assembly between the multiple batteries 10, which is beneficial to improving the space utilization of the battery 10 and the battery replacement efficiency of the battery 10.

[0155] According to some embodiments of the present application, as shown in Figures 7, 8, and 9, the adjusting member 22 is configured to individually drive each locking member 23 to move relative to the lock sleeve 21, so that the locking member 23 switches between a locked state and an unlocked state. In other words, the adjusting member 22 is selectively connected to a locking member 23 among the plurality of locking members 23, so that the adjusting member 22 can sequentially drive different locking members 23 to move relative to the lock sleeve 21, thereby sequentially driving different locking members 23 to switch between a locked state and an unlocked state.

[0156] In this embodiment, by setting the adjusting member 22 of the locking mechanism 20 as a structure for individually driving multiple locking members 23, the adjusting member 22 can individually drive each locking member 23, so that the locking force between each locking member 23 and the lock seat 300 can be adjusted by the adjusting member 22 according to the different locking conditions of each locking member 23, so as to meet the different locking requirements of the multiple locking members 23 of the locking mechanism 20, thereby expanding the scope of application of the locking mechanism 20 and improving the stability and reliability of locking the multiple locking members 23 of the locking mechanism 20 with the lock seat 300.

[0157] According to some embodiments of the present application, as shown in Figures 8 and 9, the locking mechanism 20 may further include a transmission assembly 24. The transmission assembly 24 is disposed within the lock sleeve 21, and the plurality of locking members 23 are selectively connected to the adjustment member 22 through the transmission assembly 24. The adjustment member 22 is rotatably disposed on the lock sleeve 21 about an axis extending along the first direction X. The adjustment member 22 is configured to individually drive each locking member 23 to move relative to the lock sleeve 21 when rotating relative to the lock sleeve 21, thereby switching the locking members 23 between a locked state and an unlocked state.

[0158] The transmission assembly 24 plays a role in transmitting and connecting the adjusting member 22 and one of the locking members 23 , so that the adjusting member 22 can independently drive each locking member 23 to move relative to the locking sleeve 21 through the transmission assembly 24 .

[0159] The plurality of locking members 23 are selectively connected to the adjusting member 22 via the transmission assembly 24 , that is, the adjusting member 22 is selectively connected to one of the plurality of locking members 23 via the transmission assembly 24 .

[0160] The adjusting member 22 is rotatably disposed on the lock sleeve 21 about an axis extending in the first direction X. The adjusting member 22 is configured to individually drive each locking member 23 to move relative to the lock sleeve 21 when rotating relative to the lock sleeve 21, thereby switching the locking members 23 between a locked state and an unlocked state. In other words, the adjusting member 22 is rotatable relative to the lock sleeve 21 about the axis extending in the first direction X. Rotating the adjusting member 22 drives the corresponding locking member 23 to move relative to the lock sleeve 21 via the transmission assembly 24, thereby switching the locking members 23 between a locked state and an unlocked state. Of course, in other embodiments, the adjusting member 22 may also be configured to move relative to the lock sleeve 21 to enable the locking members 23 to move relative to the lock sleeve 21.

[0161] In FIG. 9 , the adjusting member 22 is rotatably inserted into the lock sleeve 21 along the first direction X, and a portion of the adjusting member 22 passes through the lock sleeve 21 through the through hole 212 of the lock sleeve 21 along the first direction X, so that the portion of the adjusting member 22 extending out of the lock sleeve 21 can be operated by a user to drive the adjusting member 22 to rotate relative to the lock sleeve 21 to switch the state of the locking member 23.

[0162] In this embodiment, a transmission assembly 24 is provided in the lock sleeve 21 of the locking mechanism 20, and the multiple locking members 23 of the locking mechanism 20 are structured to be selectively transmission-connected to the adjusting member 22 through the transmission assembly 24, so that the adjusting member 22 can be selectively transmission-connected to one of the multiple locking members 23 through the transmission assembly 24, so that the adjusting member 22 can individually drive one of the multiple locking members 23 to move relative to the lock sleeve 21 when rotating relative to the lock sleeve 21, so that the adjusting member 22 can individually drive the single locking member 23 to switch between the locked state and the unlocked state.

[0163] According to some embodiments of the present application, please continue to refer to Figures 8 and 9, the transmission assembly 24 may include a first gear 241 and a plurality of second gears 242. The first gear 241 is fixedly sleeved on the outside of the adjustment member 22. The plurality of second gears 242 selectively engage with the first gear 241, and each locking member 23 is provided with a second gear 242. The adjustment member 22 is configured to drive the corresponding second gear 242 to rotate when the first gear 241 is engaged with the second gear 242, so as to drive the corresponding locking member 23 to move relative to the locking sleeve 21, so that the locking member 23 can switch between a locked state and an unlocked state.

[0164] Among them, the first gear 241 is fixedly sleeved on the outside of the adjusting member 22, that is, the first gear 241 is a structure sleeved on the outside of the adjusting member 22, and the first gear 241 is fixedly connected to the adjusting member 22, so that the first gear 241 and the adjusting member 22 are circumferentially locked and axially locked along the first direction X.

[0165] For example, the first gear 241 may be assembled on the adjusting member 22 in various structures. For example, the first gear 241 and the adjusting member 22 may be connected to each other by welding, interference fit, or bonding.

[0166] The plurality of second gears 242 selectively mesh with the first gear 241 , that is, the first gear 241 sleeved on the adjusting member 22 can selectively mesh with one of the plurality of second gears 242 .

[0167] Each locking member 23 is provided with a second gear 242 , that is, each second gear 242 is connected to a second gear 242 , so that the first gear 241 sleeved on the adjusting member 22 can selectively engage with the second gear 242 connected to different locking members 23 .

[0168] 8 and 9 , the locking mechanism 20 is provided with two locking members 23. Correspondingly, the transmission assembly 24 includes two second gears 242, each of which is connected to one locking member 23. Of course, in other embodiments, the number of locking members 23 and second gears 242 may also be three, four, or five.

[0169] The adjusting member 22 is configured to drive the corresponding second gear 242 to rotate when the first gear 241 is meshed with the second gear 242, so as to drive the corresponding locking member 23 to move relative to the lock sleeve 21. That is, when the first gear 241 mounted on the adjusting member 22 is meshed with one of the second gears 242 among the multiple second gears 242, the corresponding second gear 242 can be driven to rotate relative to the lock sleeve 21 by rotating the adjusting member 22, so as to further drive the locking member 23 connected to the second gear 242 to move relative to the lock sleeve 21, so that the corresponding locking member 23 can switch between the locked state and the unlocked state, thereby realizing that the adjusting member 22 can individually drive each locking member 23 to switch between the locked state and the unlocked state.

[0170] It should be noted that the structures in which the multiple second gears 242 selectively engage with the first gear 241 can be various. The multiple second gears 242 can be movably arranged in the lock sleeve 21, so that by moving different second gears 242 to engage with the first gear 241, the multiple second gears 242 can be selectively engaged with the first gear 241. For example, the second gear 242 is movably connected to the connecting portion 231 of the locking member 23 along the first direction X, and the second gear 242 is circumferentially locked with the connecting portion 231 of the locking member 23. Of course, the adjusting member 22 can also be movably arranged in the lock sleeve 21, so that by moving the adjusting member 22 to drive the first gear 241 to move in the lock sleeve 21, the first gear 241 can be selectively engaged with a second gear 242 among the multiple second gears 242.

[0171] In this embodiment, the transmission assembly 24 is provided with a first gear 241 and multiple second gears 242. The first gear 241 is fixedly mounted on the adjusting member 22, and each second gear 242 is connected to a locking member 23, and the multiple second gears 242 can selectively engage with the second gear 242, so that the first gear 241 mounted on the adjusting member 22 can selectively engage with one of the multiple second gears 242, so that when the adjusting member 22 rotates relative to the lock sleeve 21, the mutual engagement of the first gear 241 and the second gear 242 can drive the corresponding locking member 23 to move relative to the lock sleeve 21, thereby realizing that the adjusting member 22 can individually drive each locking member 23 to switch between the locked state and the unlocked state through the transmission assembly 24. The structure is simple and easy to implement.

[0172] In some embodiments, as shown in FIG. 9 , the adjusting member 22 is movably disposed on the locking sleeve 21 along the first direction X. The adjusting member 22 is configured to move along the first direction X to drive the first gear 241 to selectively engage with one of the plurality of second gears 242 .

[0173] The adjusting member 22 is movably disposed on the locking sleeve 21 along the first direction X. Movement of the adjusting member 22 along the first direction X drives the first gear 241, which is sleeved on the outer side of the adjusting member 22, to move along the first direction X, so that the first gear 241 can sequentially engage with different second gears 242 among the plurality of second gears 242. In other words, the plurality of second gears 242 are staggered in the first direction X, so that the first gear 241 can engage with different second gears 242 as it moves along the first direction X.

[0174] Optionally, as shown in Figures 8 and 9, the second gear 242 may include a main body 2421 and a toothed member 2422, the main body 2421 is connected to the locking member 23, the toothed member 2422 is fixedly sleeved on the outer side of the main body 2421, the toothed member 2422 includes a plurality of teeth arranged in sequence along the circumference of the main body 2421, and the plurality of teeth of the toothed member 2422 all extend along the first direction X so that the toothed member 2422 can engage with the first gear 241, and the toothed members 2422 of the plurality of second gears 242 are arranged at intervals along the first direction X.

[0175] Among them, the toothed parts 2422 of multiple second gears 242 are arranged at intervals along the first direction X, so that the first gear 241 can engage with the toothed parts 2422 of different second gears 242 when moving along the first direction X, so that the first gear 241 can selectively engage with one of the multiple second gears 242.

[0176] Exemplarily, the main body 2421 and the locking member 23 are threadedly connected. The main body 2421 of the second gear 242 is sleeved on the outside of the connecting portion 231 of the locking member 23 and is threadedly connected to the connecting portion 231 of the locking member 23, so that when the second gear 242 rotates, it can drive the connecting portion 231 of the locking member 23 to rotate relative to the lock sleeve 21, so as to drive the clamping portion 232 of the locking member 23 to be clamped or unclamped with the lock seat 300, and when the rotation of the connecting portion 231 of the locking member 23 relative to the lock sleeve 21 is restricted, the second gear 242 can also apply a feed force along the first direction X to the connecting portion 231 of the locking member 23 through the threaded structure to drive the connecting portion 231 to move along the first direction X.

[0177] It should be noted that, in other embodiments, the toothed parts 2422 of the multiple second gears 242 can also be a structure located at the same position in the first direction X, so that the first gear 241 of the adjusting part 22 is a structure that is simultaneously engaged with the toothed parts 2422 of the multiple second gears 242. The locking mechanism 20 adopting this structure can simultaneously drive the multiple second gears 242 to rotate relative to the locking sleeve 21 through the adjusting part 22, so as to drive the multiple locking parts 23 to move relative to the locking sleeve 21 at the same time, thereby realizing the simultaneous movement and switching of the multiple locking parts 23 between the locked state and the unlocked state.

[0178] In this embodiment, by configuring the adjusting member 22 to be movably disposed in the lock sleeve 21 along the first direction X, the adjusting member 22 can drive the first gear 241 to move along the first direction X when moving along the first direction X, so that the first gear 241 can engage with different second gears 242 during the process of moving along the first direction X, thereby achieving the first gear 241 sleeved on the adjusting member 22 being able to selectively engage with one of the multiple second gears 242. The structure is simple and easy to assemble.

[0179] According to some embodiments of the present application, with reference to Figures 8 and 9, and further with reference to Figure 10, Figure 10 is a partial enlarged view of point A of the locking mechanism 20 shown in Figure 9. The locking mechanism 20 may further include a first clutch 25 and a second clutch 26. The first clutch 25 is provided on the lock sleeve 21, and the second clutch 26 is provided on the adjustment member 22. The first clutch 25 and the second clutch 26 are configured to: limit the adjustment member 22 from rotating relative to the lock sleeve 21 when they are engaged with each other; and allow the adjustment member 22 to rotate relative to the lock sleeve 21 when they are disengaged from each other. When the first clutch 25 and the second clutch 26 are engaged with each other, the first gear 241 is engaged with one of the second gears 242 among the plurality of second gears 242.

[0180] Among them, the first clutch 25 and the second clutch 26 are used to selectively lock the adjusting member 22 and the locking sleeve 21 to limit the adjusting member 22 from rotating relative to the locking sleeve 21. That is, the first clutch 25 and the second clutch 26 can selectively lock or unlock the adjusting member 22 and the locking sleeve 21. When the first clutch 25 and the second clutch 26 lock the adjusting member 22 and the locking sleeve 21, the adjusting member 22 cannot rotate relative to the locking sleeve 21. When the first clutch 25 and the second clutch 26 unlock the adjusting member 22 and the locking sleeve 21, the adjusting member 22 can rotate relative to the locking sleeve 21.

[0181] The first clutch member 25 and the second clutch member 26 can restrict the adjustment member 22 from rotating relative to the lock sleeve 21 when they are engaged with each other. Conversely, when the first clutch member 25 and the second clutch member 26 are disengaged from each other, the adjustment member 22 can be allowed to rotate relative to the lock sleeve 21. Optionally, the structures of the first clutch 25 and the second clutch 26 can be various. For example, the first clutch 25 can be a structure fixed to the inner side of the lock sleeve 21. Correspondingly, the second clutch 26 is movably arranged on the outer side of the adjusting member 22 along the first direction X and is circumferentially locked with the adjusting member 22. That is, the second clutch 26 can move relative to the adjusting member 22 along the first direction X but cannot rotate circumferentially relative to the adjusting member 22, so that when the second clutch 26 moves along the first direction X to engage with the first clutch 25, the first clutch 25 and the second clutch 26 can cooperate to limit the rotation of the adjusting member 22 relative to the lock sleeve 21. Conversely, when the first clutch 25 and the second clutch 26 are disengaged from each other, the adjusting member 22 can be allowed to rotate relative to the lock sleeve 21. Of course, the structure of the locking mechanism 20 is not limited to this. In other embodiments, the locking mechanism 20 can also be other structures. For example, the first clutch member 25 can also be a structure that is movably arranged in the lock sleeve 21 along the first direction X and is circumferentially locked with the lock sleeve 21. Correspondingly, the second clutch member 26 is fixedly sleeved on the outside of the adjusting member 22. It can also be that the first clutch member 25 is fixed in the lock sleeve 21, and the second clutch member 26 is fixedly sleeved on the outside of the adjusting member 22, and the adjusting member 22 is movably arranged in the lock sleeve 21 along the first direction X, so that when the adjusting member 22 moves along the first direction X, it can drive the second clutch member 26 to engage with or disengage from the first clutch member 25.

[0182] It should be noted that in Figure 9, in the embodiment in which multiple second gears 242 are selectively engaged with the first gear 241, and when the first clutch 25 and the second clutch 26 are engaged with each other, the first gear 241 is engaged with one of the multiple second gears 242, so that when the first clutch 25 and the second clutch 26 cooperate to limit the rotation of the adjustment member 22 relative to the lock sleeve 21, only the corresponding one locking member 23 can be restricted from moving relative to the lock sleeve 21. Of course, in the embodiment in which the first gear 241 is engaged with multiple second gears 242, when the first clutch 25 and the second clutch 26 are engaged with each other, the first clutch 25 and the second clutch 26 cooperate to limit the rotation of the adjustment member 22 relative to the lock sleeve 21, which can simultaneously restrict the movement of multiple locking members 23 relative to the lock sleeve 21.

[0183] In this embodiment, the locking mechanism 20 is further provided with a first clutch member 25 and a second clutch member 26 that can be engaged with or disengaged from each other, and the first clutch member 25 and the second clutch member 26 are respectively provided on the lock sleeve 21 and the adjusting member 22, so that the adjusting member 22 can be restricted from rotating relative to the lock sleeve 21 by engaging with the first clutch member 25 and the second clutch member 26, and the adjusting member 22 can be allowed to rotate relative to the lock sleeve 21 after the first clutch member 25 and the second clutch member 26 are disengaged from each other, so as to realize the function of the first clutch member 25 and the second clutch member 26 selectively locking the adjusting member 22 and the lock sleeve 21, thereby alleviating the phenomenon of the engagement failure of the locking member 23 and the lock seat 300 caused by the erroneous rotation of the adjusting member 22, thereby improving the locking effect between the locking member 23 and the lock seat 300, and facilitating the stability and reliability of the mutual locking between the locking mechanism 20 and the lock seat 300.

[0184] In some embodiments, referring to Figures 8, 9, and 10, the first clutch member 25 and the second clutch member 26 are arranged along the first direction X. The first clutch member 25 is fixed to the lock sleeve 21, and the second clutch member 26 is fixed to the adjustment member 22. The adjustment member 22 is configured to drive the second clutch member 26 to move along the first direction X when moving along the first direction X, so that the second clutch member 26 can engage with or disengage from the first clutch member 25.

[0185] Among them, the first clutch member 25 is fixed to the inner side of the lock sleeve 21, and the fixing structure between the first clutch member 25 and the lock sleeve 21 can be various. For example, the first clutch member 25 can be fixedly connected to the lock sleeve 21 by a threaded connection, welding connection, bonding, clamping or interference fit structure.

[0186] For example, referring to Figures 9 and 10, and further referring to Figure 11, Figure 11 is a cross-sectional view of a lock sleeve 21 of a locking mechanism 20 provided in some embodiments of the present application. A through hole 212 for the adjustment member 22 to pass through is provided at one end of the lock sleeve 21 in the first direction X. The first clutch member 25 is screwed onto the wall surface of the through hole 212. In other words, an external thread is formed on the outer peripheral surface of the first clutch member 25, and an internal thread is formed on the wall surface of the through hole 212. The external thread of the first clutch member 25 cooperates with the internal thread formed on the wall surface of the through hole 212, so that the first clutch member 25 is screwed into the through hole 212 of the lock sleeve 21.

[0187] The second clutch member 26 is fixed to the adjusting member 22. The adjusting member 22 is configured to drive the second clutch member 26 to move along the first direction X when moving along the first direction X. That is, the second clutch member 26 and the adjusting member 22 are circumferentially locked and axially locked along the first direction X. Therefore, when the adjusting member 22 is moved along the first direction X to drive the first gear 241 to engage with a different second gear 242, the adjusting member 22 can also drive the second clutch member 26 to move along the first direction X relative to the first clutch member 25, so that the second clutch member 26 can engage with or disengage from the first clutch member 25 when moving along the first direction X.

[0188] Optionally, the second clutch member 26 may be fixed to the adjusting member 22 in various structures. For example, the second clutch member 26 may be fixed to the adjusting member 22 by threaded connection, welding connection, bonding, snap connection or interference fit.

[0189] For example, referring to Figures 8, 9, and 10, and further referring to Figures 12, 13, and 14, Figure 12 is a cross-sectional view of the adjustment member 22 of the locking mechanism 20 provided in some embodiments of the present application, Figure 13 is a schematic structural diagram of the first clutch member 25 of the locking mechanism 20 provided in some embodiments of the present application, and Figure 14 is a schematic structural diagram of the second clutch member 26 of the locking mechanism 20 provided in some embodiments of the present application. The adjustment member 22 includes a first assembly segment 221 and a second assembly segment 222 arranged and connected along a first direction X. The second assembly segment 222 is protruding from one end of the first assembly segment 221 along the first direction X. The second assembly segment 222 is inserted through the through hole 212 of the locking sleeve 21 along the first direction X and extends out of the locking sleeve 21. The first clutch member 25 is provided with a first hole 251 for the second assembly segment 222 to pass through. The first hole 251 extends through both ends of the first clutch member 25 along the first direction X, and a gap is provided between the wall surface of the first hole 251 and the outer peripheral surface of the second assembly segment 222. The first gear 241 is fixedly sleeved on the outside of the first assembly section 221 of the adjusting member 22, and the second clutch member 26 is sleeved on the outside of the second assembly section 222 of the adjusting member 22, and the second clutch member 26 and the second assembly section 222 are interference fit to achieve the fixing of the second clutch member 26 on the adjusting member 22.

[0190] Among them, the second clutch component 26 is provided with a second hole 261 for the second assembly section 222 of the adjusting component 22 to be inserted, so that the second clutch component 26 can be sleeved on the outside of the second assembly section 222 of the adjusting component 22, and the hole wall surface of the second hole 261 is interference fit with the outer peripheral surface of the second assembly section 222 to realize the fixing of the second clutch component 26 on the adjusting component 22.

[0191] In this embodiment, the first clutch member 25 and the second clutch member 26 are arranged along the first direction X. By fixing the first clutch member 25 to the lock sleeve 21 and fixing the second clutch member 26 to the adjustment member 22, the adjustment member 22 can be moved along the first direction X to drive the second clutch member 26 to engage or disengage with the first clutch member 25, thereby limiting the rotation of the adjustment member 22 relative to the lock sleeve 21 or allowing the adjustment member 22 to rotate relative to the lock sleeve 21. The structure is simple and easy to operate and implement.

[0192] According to some embodiments of the present application, as shown in Figures 8 and 9, the locking mechanism 20 may further include an elastic member 27. The elastic member 27 is disposed between the locking sleeve 21 and the adjusting member 22. The elastic member 27 is configured to drive the adjusting member 22 to move along the first direction X, so as to move the second clutch member 26 along the first direction X toward the first clutch member 25, so that the second clutch member 26 engages with the first clutch member 25.

[0193] The spring 27 is arranged between the lock sleeve 21 and the adjusting member 22, so that the spring 27 can provide an elastic force for the adjusting member 22, so that the adjusting member 22 has a tendency to drive the second clutch member 26 to move in the direction close to the first clutch member 25 in the first direction X. Therefore, in actual use, it is only necessary to overcome the elastic force of the spring 27 and push the adjusting member 22 to move, so as to drive the second clutch member 26 to disengage from the first clutch member 25, and drive the first gear 241 to engage with a different second gear 242, thereby driving the adjusting member 22 to rotate relative to the lock sleeve 21 to realize the corresponding locking member 23 to switch between the locked state and the unlocked state. Conversely, after the state switching of the locking member 23 is completed, it is only necessary to cancel the force pushing the adjusting member 22 so that the adjusting member 22 can be reset under the elastic force of the spring 27, so that the adjusting member 22 drives the second clutch member 26 and the first clutch member 25 to approach each other and engage with each other, so as to realize the rotation restriction function between the adjusting member 22 and the lock sleeve 21.

[0194] Optionally, the elastic member 27 can have various structures, for example, the elastic member 27 can be a spring, a spring sheet, or an elastic rubber, etc., disposed between the lock sleeve 21 and the adjustment member 22. For example, in FIG9 , the elastic member 27 is a spring, and the elastic member 27 is sleeved on the outside of the adjustment member 22.

[0195] In this embodiment, the locking mechanism 20 is further provided with an elastic member 27, and the elastic member 27 is arranged between the lock sleeve 21 and the adjusting member 22. The elastic member 27 can apply a force to the adjusting member 22 in the first direction X to drive the second clutch member 26 to move toward the first clutch member 25, so that the first clutch member 25 and the second clutch member 26 are engaged with each other. As a result, the elastic member 27 can realize the automatic reset of the adjusting member 22 in the first direction X to the position where the first clutch member 25 and the second clutch member 26 are engaged with each other. On the one hand, the locking mechanism 20 with such a structure can further improve the stability of the mutual engagement of the first clutch member 25 and the second clutch member 26, thereby reducing the phenomenon of accidental disengagement of the first clutch member 25 and the second clutch member 26. On the other hand, after the second clutch member 26 and the first clutch member 25 are disengaged from each other, the elastic member 27 can drive the adjusting member 22 to move along the first direction X and realize the automatic engagement of the second clutch member 26 and the first clutch member 25, without manual intervention, which is convenient for operation and use.

[0196] In some embodiments, as shown in Figures 9, 10, and 12, the adjustment member 22 may include a guide segment 223, a first assembly segment 221, and a second assembly segment 222, which are sequentially connected. Along the first direction X, the guide segment 223 and the second assembly segment 222 are respectively projected from both ends of the first assembly segment 221. A first gear 241 is fixedly sleeved on the outside of the first assembly segment 221, a second clutch member 26 is fixedly sleeved on the outside of the second assembly segment 222, and an elastic member 27 is sleeved on the guide segment 223. The elastic member 27 abuts the locking sleeve 21 and the first assembly segment 221 at both ends in the first direction X.

[0197] Among them, the guide section 223 and the second assembly section 222 are respectively protruded from the two ends of the first assembly section 221, that is, the guide section 223 and the second assembly section 222 are structures respectively connected to the end faces of the two ends of the first assembly section 221 in the first direction X, and the outer diameter of the first assembly section 221 is larger than the outer diameter of the first assembly section 221 and the outer diameter of the guide section 223, so that the guide section 223 and the second assembly section 222 are structures respectively protruded from the two ends of the first assembly section 221.

[0198] The second clutch member 26 is fixedly sleeved on the outer side of the second assembly section 222 , that is, the second assembly section 222 of the adjustment member 22 is inserted into the second hole 261 of the second clutch member 26 , and the second assembly section 222 and the second clutch member 26 are fixedly connected to each other.

[0199] The elastic member 27 is sleeved on the guide section 223, and the two ends of the elastic member 27 in the first direction X are respectively abutted against the lock sleeve 21 and the first assembly section 221. That is, the elastic member 27 is a structure sleeved on the outside of the guide section 223 of the adjusting member 22, and the elastic member 27 is compressed between the lock sleeve 21 and the end of the first assembly section 221 close to the guide section 223 in the first direction X, so that the two ends of the elastic member 27 can respectively abut against the lock sleeve 21 and the first assembly section 221, so that the elastic member 27 can provide elastic force to the first assembly section 221 along the first direction X, so as to drive the adjusting member 22 to move in the direction of the second clutch member 26 close to the first clutch member 25.

[0200] It should be noted that the elastic member 27 and the lock sleeve 21 can be in direct contact or indirect contact via other blocks or gaskets. Similarly, the elastic member 27 and the first assembly section 221 of the adjustment member 22 can be in direct contact or indirect contact via other blocks or gaskets.

[0201] In this embodiment, the adjusting member 22 is provided with a guide section 223, a first assembly section 221 and a second assembly section 222, and the guide section 223 and the second assembly section 222 are respectively protruded at the two ends of the first assembly section 221 in the first direction X. By fixing the first gear 241 and the second clutch member 26 on the outer sides of the first assembly section 221 and the second assembly section 222, and sleeved the elastic member 27 on the outer side of the guide section 223, so that the two ends of the elastic member 27 can respectively abut against the lock sleeve 21 and the first assembly section 221, the locking mechanism 20 with such a structure can reduce the friction between the locking sleeve 21 and the first assembly section 221. The interference between the first gear 241, the second clutch member 26 and the elastic member 27 facilitates assembly and facilitates the elastic member 27 to apply elastic force to the adjusting member 22, so that the elastic member 27 drives the adjusting member 22 to move along the first direction X toward the second clutch member 26 close to the first clutch member 25. On the other hand, the guide section 223 can play a certain guiding role on the elastic member 27 to achieve stable compression of the elastic member 27 along the first direction X, which is conducive to alleviating radial deformation or bending of the elastic member 27, thereby improving the stability and reliability of the elastic member 27.

[0202] According to some embodiments of the present application, referring to Figures 8, 9, 13, and 14, along the first direction X, a first toothed portion 252 is provided at one end of the first clutch member 25 facing the second clutch member 26, and a second toothed portion 262 is provided at one end of the second clutch member 26 facing the first clutch member 25. The second toothed portion 262 is configured to engage with the first toothed portion 252 to achieve a snap-fit ​​engagement between the second clutch member 26 and the first clutch member 25.

[0203] The first toothed portion 252 is a toothed structure provided on the end of the first clutch member 25 facing the second clutch member 26 in the first direction X. The multiple teeth of the first toothed portion 252 are arranged circumferentially of the first clutch member 25, and each tooth extends radially of the first clutch member 25, so that the first toothed portion 252 is provided around the second assembly section 222 of the adjusting member 22. The second toothed portion 262 is a toothed structure provided on the end of the second clutch member 26 facing the first clutch member 25 in the first direction X. The multiple teeth of the second toothed portion 262 are arranged circumferentially of the second clutch member 26, and each tooth extends radially of the second clutch member 26, so that the second toothed portion 262 is provided around the second assembly section 222 of the adjusting member 22. When the adjusting member 22 drives the second clutch member 26 to move along the first direction X and approaches the first clutch member 25, the second tooth-shaped portion 262 and the first tooth-shaped portion 252 can engage with each other, thereby realizing the mutual engagement of the second clutch member 26 and the first clutch member 25 to restrict the adjusting member 22 from rotating relative to the locking sleeve 21. Conversely, after the first tooth-shaped portion 252 and the second tooth-shaped portion 262 are disengaged from each other, the adjusting member 22 can be allowed to rotate relative to the locking sleeve 21.

[0204] It should be noted that, in other embodiments, the first clutch member 25 and the second clutch member 26 may also be other structures. For example, a limiting hole is provided at one end of the first clutch member 25 facing the second clutch member 26 in the first direction X, and a latch is provided at one end of the second clutch member 26 facing the first clutch member 25 in the first direction X. When the adjusting member 22 drives the second clutch member 26 to move along the first direction X and approaches the first clutch member 25, the latch can be inserted into the limiting hole to achieve mutual engagement between the second clutch member 26 and the first clutch member 25, thereby limiting the rotation of the adjusting member 22 relative to the lock sleeve 21.

[0205] In this embodiment, a first tooth-shaped portion 252 is provided on one end of the first clutch member 25 facing the second clutch member 26, and correspondingly, a second tooth-shaped portion 262 is provided on one end of the second clutch member 26 facing the first clutch member 25, so that when the adjusting member 22 drives the second clutch member 26 to move along the first direction X, the second tooth-shaped portion 262 can be engaged with or disengaged from the first tooth-shaped portion 252, thereby realizing the snap-fitting or disengagement of the second clutch member 26 and the first clutch member 25, so that when the first tooth-shaped portion 252 and the second tooth-shaped portion 262 are engaged with each other, the first clutch member 25 and the second clutch member 26 can cooperate to restrict the adjustment member 22 from rotating relative to the lock sleeve 21. The structure is simple and easy to implement. In addition, by respectively arranging the first tooth-shaped portion 252 and the second tooth-shaped portion 262 on the first clutch member 25 and the second clutch member 26, it is convenient for the first clutch member 25 and the second clutch member 26 to engage or disengage, which is beneficial to reducing the difficulty of engaging and disengaging the first clutch member 25 and the second clutch member 26 with each other.

[0206] In some embodiments, as shown in FIG10 , along the first direction X, a first inclined surface 253 is formed on one end of the first clutch member 25 facing the second clutch member 26, and a second inclined surface 263 is formed on one end of the second clutch member 26 facing the first clutch member 25. The second inclined surface 263 mates with the first inclined surface 253. The first tooth-shaped portion 252 is disposed on the first inclined surface 253, and the second tooth-shaped portion 262 is disposed on the second inclined surface 263.

[0207] The second inclined surface 263 matches the first inclined surface 253 , that is, the first inclined surface 253 on the first clutch 25 and the second inclined surface 263 on the second clutch 26 have the same shape, so that the first inclined surface 253 can fit the second inclined surface 263 .

[0208] The first tooth-shaped portion 252 is disposed on the first inclined surface 253 , and the second tooth-shaped portion 262 is disposed on the second inclined surface 263 . That is, the first tooth-shaped portion 252 protrudes from the first inclined surface 253 , and the second tooth-shaped portion 262 protrudes from the second inclined surface 263 .

[0209] In this embodiment, a first inclined surface 253 is provided at one end of the first clutch member 25 facing the second clutch member 26, and the first tooth-shaped portion 252 is provided on the first inclined surface 253. Correspondingly, a second inclined surface 263 that matches the first inclined surface 253 is provided at one end of the second clutch member 26 facing the first clutch member 25, and the second tooth-shaped portion 262 is provided on the second inclined surface 263. This structure can achieve that the first tooth-shaped portion 252 and the second tooth-shaped portion 262 are inclined structures that match each other, thereby playing a certain guiding role and facilitating the mutual engagement of the first tooth-shaped portion 252 and the second tooth-shaped portion 262.

[0210] In some embodiments, referring to FIG. 10 , FIG. 13 and FIG. 14 , the first inclined surface 253 is a concave surface provided on the first clutch member 25 , and the second inclined surface 263 is a convex surface provided on the second clutch member 26 .

[0211] The first inclined surface 253 is a concave surface provided on the first clutch member 25 , that is, the first inclined surface 253 is an inclined surface provided on one end of the first clutch member 25 facing the second clutch member 26 and is concave inward, so that the first inclined surface 253 is a conical surface concave toward the interior of the first clutch member 25 .

[0212] The second inclined surface 263 is a convex surface provided on the second clutch member 26 , that is, the second inclined surface 263 is provided on the end of the second clutch member 26 facing the first clutch member 25 and protrudes outward, so that the second inclined surface 263 is a conical surface protruding toward the outside of the second clutch member 26 .

[0213] In this embodiment, by setting the first inclined surface 253 as a concave surface and the second inclined surface 263 as a convex surface, the second clutch component 26 can be inserted into the first clutch component 25 when the second tooth-shaped portion 262 of the second clutch component 26 is engaged with the first tooth-shaped portion 252 of the first clutch component 25, thereby facilitating the improvement of the stability and reliability of the mutual engagement between the second clutch component 26 and the first clutch component 25, and reducing the phenomenon of slippage between the second clutch component 26 and the first clutch component 25 when they are engaged with each other.

[0214] According to some embodiments of the present application, as shown in Figures 7, 8, and 9, the locking member 23 may include a connecting portion 231 and a clamping portion 232. The connecting portion 231 extends along a first direction X and is inserted into the lock sleeve 21. The connecting portion 231 is connected to a second gear 242. The clamping portion 232 is located outside the lock sleeve 21 and is connected to the end of the connecting portion 231 away from the lock sleeve 21. The clamping portion 232 protrudes from the outer circumference of the connecting portion 231 along its extension direction. The clamping portion 232 is configured to engage with the lock base 300. The extension direction of the clamping portion 232 is perpendicular to the first direction X. The second gear 242 is configured to rotate relative to the lock sleeve 21 to drive the corresponding connecting portion 231 of the locking member 23 to rotate, thereby engaging or disengaging the clamping portion 232 with the lock base 300, thereby switching the locking member 23 between a locked state and an unlocked state.

[0215] The connecting portion 231 of the locking member 23 is a cylindrical structure extending along the first direction X. A portion of the connecting portion 231 is inserted into the locking sleeve 21 along the first direction X. The connecting portion 231 extends through the assembly hole 211 of the locking sleeve 21 along the first direction X. One end of the connecting portion 231 extending out of the locking sleeve 21 through the assembly hole 211 is connected to the engaging portion 232. The end of the connecting portion 231, distal from the engaging portion 232 in the first direction X, is connected to the main body 2421 of the second gear 242. The main body 2421 of the second gear 242 is threadedly engaged with the outer side of the engaging portion 232. In other words, the portion of the connecting portion 231 inserted into the main body 2421 of the first gear 241 is provided with external threads. Correspondingly, the main body 2421 of the first gear 241 is provided with internal threads, enabling the main body 2421 of the second gear 242 to be threadedly engaged with the outer side of the engaging portion 232. Of course, in other embodiments, the connecting portion 231 may be screwed to the outside of the main body 2421, that is, the connecting portion 231 is provided with an internal thread, and correspondingly, the portion of the main body 2421 of the first gear 241 accommodated in the connecting portion 231 is provided with an external thread, so that the connecting portion 231 can be screwed to the outside of the main body 2421.

[0216] The clamping portion 232 is located outside the locking sleeve 21 and is connected to one end of the connecting portion 231 away from the locking sleeve 21, that is, the connecting portion 231 has a portion extending out of the locking sleeve 21 through the assembly hole 211 in the first direction X, and the clamping portion 232 is connected to one end of the portion of the connecting portion 231 extending out of the locking sleeve 21, so that the clamping portion 232 is arranged at an interval from the locking sleeve 21 along the first direction X.

[0217] The clamping portion 232 protrudes from the outer peripheral surface of the connecting portion 231 along its extension direction, that is, in the extension direction of the clamping portion 232, the clamping portion 232 extends beyond the outer peripheral surface of the connecting portion 231. For example, in FIG9 , the extension direction of the clamping portion 232 is perpendicular to the first direction X, so that the clamping portion 232 and the connecting portion 231 form a "T"-shaped structure. Of course, in other embodiments, the clamping portion 232 and the connecting portion 231 may also form an "L"-shaped structure.

[0218] The second gear 242 is configured to drive the corresponding connecting portion 231 of the locking member 23 to rotate when it rotates relative to the lock sleeve 21, so that the clamping portion 232 is clamped or released from the lock seat 300, so that the locking member 23 switches between the locked state and the unlocked state, that is, the adjusting member 22 can drive the first gear 241 to rotate when it rotates relative to the lock sleeve 21, so as to drive the second gear 242 engaged with the first gear 241 to rotate, so that the second gear 242 can drive the corresponding connecting portion 231 of the locking member 23 to rotate around the axis extending along the first direction X, thereby changing the extension direction of the clamping portion 232, so that the clamping portion 232 can overlap the lock seat 300 or release the overlap from the lock seat 300, so that the clamping portion 232 can be clamped or released from the lock seat 300.

[0219] In some embodiments, referring to Figures 8 and 9, and further referring to Figure 15, Figure 15 is a schematic diagram of the assembly of the lock base 300 and the locking member 23 of the locking mechanism 20 provided in some embodiments of the present application, which are locked to each other. The lock base 300 is provided with a lock hole 301 for the locking member 23 to be inserted. The lock hole 301 passes through both sides of the lock base 300 along the first direction X. After the locking member 23 is inserted into the lock hole 301, the rotating adjustment member 22 can drive the corresponding locking portion 232 of the locking member 23 to rotate around the axis extending along the first direction X through the transmission assembly 24, so that the locking portion 232 can engage with the surface of the lock base 300 on the side away from the lock sleeve 21, so that the locking mechanism 20 and the lock base 300 are locked in the first direction. When the locking mechanism 20 and the lock seat 300 are mutually locked, the locking mechanism 20 and the lock seat 300 are mutually engaged. Conversely, when the rotating adjustment member 22 drives the corresponding locking member 23's clamping portion 232 to rotate through the transmission assembly 24 until the projection of the clamping portion 232 in the first direction X is located in the lock hole 301, the locking member 23 can be withdrawn from the lock hole 301, so that the locking mechanism 20 and the lock seat 300 can be disengaged in the first direction X, thereby realizing the mutual unlocking between the locking mechanism 20 and the lock seat 300.

[0220] Among them, the cross-section of the lock hole 301 is rectangular. When the extension direction of the clamping portion 232 is consistent with the length direction of the cross-section of the lock hole 301, the clamping portion 232 can be inserted into the lock hole 301 or can be withdrawn from the lock hole 301. When the clamping portion 232 passes through the lock hole 301 and the extension direction of the clamping portion 232 intersects with the length direction of the cross-section of the lock hole 301, the clamping portion 232 can be engaged with the surface of the lock seat 300 on the side facing away from the lock sleeve 21.

[0221] Optionally, a card slot 302 is further provided on the surface of the lock seat 300 for the engaging portion 232, and the extending direction of the card slot 302 is perpendicular to the length direction of the cross section of the lock hole 301. When the card slot 232 is rotated so that the extending direction is perpendicular to the length direction of the cross section of the lock hole 301, the card slot 302 can engage with the lock seat 300, and the card slot 302 can be inserted into the card slot 302 to alleviate the shaking phenomenon between the locking mechanism 20 and the lock seat 300, thereby helping to improve the stability of the mutual locking of the locking mechanism 20 and the lock seat 300.

[0222] The locking member 230 is provided with a connecting portion 231 and a clamping portion 232 connected to one end of the connecting portion 231, and the clamping portion 232 protrudes from the outer peripheral surface of the connecting portion 231 in its extension direction. By inserting the connecting portion 231 into the lock sleeve 21 along the first direction X and connecting the second gear 242 to each other, the adjusting member 22 can drive the corresponding second gear 242 to rotate when the first gear 241 and the second gear 242 are engaged, thereby driving the corresponding connecting portion 231 of the locking member 23 to rotate relative to the lock sleeve 21, so that the clamping portion 232 can rotate with the connecting portion 231, thereby realizing that the extension direction of the clamping portion 232 is changed in a plane perpendicular to the first direction X, so that the clamping portion 232 can be engaged with or disengaged from the lock seat 300 after rotation, thereby realizing that the locking member 23 of the locking mechanism 20 can be engaged with or disengaged from the lock seat 300 in the first direction X.

[0223] According to some embodiments of the present application, referring to Figures 8, 9 and 11, the locking sleeve 21 is provided with a first limiting portion 213, and the connecting portion 231 is provided with a second limiting portion 2311. The first limiting portion 213 and the second limiting portion 2311 cooperate to limit the rotation angle of the locking member 23.

[0224] The first limiting portion 213 and the second limiting portion 2311 play the role of cooperating to limit the rotation angle of the connection portion 231 relative to the lock sleeve 21. The structures of the first limiting portion 213 and the second limiting portion 2311 can be various. For example, the first limiting portion 213 can be a limiting groove 28 provided on the inner circumference of the lock sleeve 21, and correspondingly, the second limiting portion 2311 can be a limiting protrusion 29 protruding from the outer circumference of the connection portion 231. The limiting protrusion 29 is inserted into the limiting groove 28 to cooperate to achieve the limitation of the rotation angle of the connection portion 231. Of course, the first limiting portion 213 and the second limiting portion 2311 can also be both limiting protrusions 29. The first limiting portion 213 is protruded from one end of the lock sleeve 21 in the first direction X, and the second limiting portion 2311 is protruded from the outer circumference of the connection portion 231. The second limiting portion 2311 can abut against the first limiting portion 213 when the connecting portion 231 rotates relative to the locking sleeve 21 , so as to limit the rotation angle of the connecting portion 231 through the cooperation between the first limiting portion 213 and the second limiting portion 2311 .

[0225] Optionally, the number of the first limiting portions 213 and the second limiting portions 2311 provided between each locking member 23 and the locking sleeve 21 may be one or more. For example, in Figures 8 and 9, each locking member 23 is provided with two second limiting portions 2311, and the two second limiting portions 2311 are respectively provided on both sides of the connecting portion 231 along the radial direction of the connecting portion 231. Correspondingly, the locking sleeve 21 is provided with two first limiting portions 213 corresponding to each locking member 23.

[0226] In this embodiment, by correspondingly providing the first limiting portion 213 and the second limiting portion 2311 on the lock sleeve 21 and the connecting portion 231 respectively, the first limiting portion 213 and the second limiting portion 2311 can cooperate to limit the rotation angle of the connecting portion 231, so that the connecting portion 231 drives the clamping portion 232 to be clamped or released with the lock seat 300 under the cooperation restriction of the first limiting portion 213 and the second limiting portion 2311, thereby facilitating the switching of the locking member 23 between the locked state and the unlocked state. The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping portion 232 cannot be clamped with the lock seat 300 due to the excessive rotation angle of the clamping portion 232 following the connecting portion 231, which is beneficial to improving the reliability of the mutual locking between the locking mechanism 20 and the lock seat 300.

[0227] According to some embodiments of the present application, as shown in Figures 8 and 9 , the connecting portion 231 is threadedly connected to the second gear 242, and the first limiting portion 213 and the second limiting portion 2311 are further configured to cooperate and guide the connecting portion 231 to move along the first direction X when the second gear 242 drives the corresponding locking member 23 to rotate, so that the locking member 23 moves between the first position and the second position along the first direction X. When the locking member 23 is in the first position, the locking member 23 is in a locked state, so that the engaging portion 232 can engage with the lock base 300; when the locking member 23 is in the second position, the locking member 23 is in an unlocked state, so that the engaging portion 232 can be released from the lock base 300.

[0228] The first limiting portion 213 and the second limiting portion 2311 are further configured to cooperate and guide the connecting portion 231 to move along the first direction X when the second gear 242 drives the corresponding locking member 23 to rotate, that is, when the adjusting member 22 drives the corresponding connecting portion 231 to rotate relative to the lock sleeve 21 through the transmission assembly 24, the first limiting portion 213 and the second limiting portion 2311 cooperate to limit the rotation angle of the connecting portion 231 while guiding the connecting portion 231 to move relative to the lock sleeve 21 in the first direction X, so that the locking member 23 has two end positions relative to the lock sleeve 21 in the first direction X, namely the first position and the second position. The second position, that is, while the adjusting member 22 drives the corresponding connecting portion 231 to rotate relative to the lock sleeve 21 through the transmission assembly 24, the connecting portion 231 can also move relative to the lock sleeve 21 along the first direction X, so that when the connecting portion 231 drives the clamping portion 232 to rotate until the clamping portion 232 can engage with the side of the lock seat 300 away from the lock sleeve 21, the locking member 23 is in the first position. Correspondingly, when the locking member 23 moves to the second position, the projection of the clamping portion 232 in the first direction X is located in the lock hole 301 of the lock seat 300, so that the locking member 23 can disengage from the lock seat 300 along the first direction X.

[0229] When the adjusting member 22 rotates relative to the locking sleeve 21, the transmission assembly 24 can drive the connecting portion 231 to rotate and drive the connecting portion 231 to move along the first direction X. For example, in Figure 9, the main body 2421 of the second gear 242 of the transmission assembly 24 and the connecting portion 231 are threadedly connected, so that the adjusting member 22 can drive the corresponding connecting portion 231 to rotate through the transmission assembly 24, and when the circumferential rotation of the connecting portion 231 is restricted, the second gear 242 can provide the connecting portion 231 with a feed force along the first direction X, so that the connecting portion 231 can move along the first direction X.

[0230] In this embodiment, by setting the connecting portion 231 and the second gear 242 as a structure in which they are threadedly connected to each other, the locking mechanism 20 with such a structure enables the second gear 242 to apply a feeding force to the connecting portion 231 to move along the first direction X when the rotation of the connecting portion 231 is restricted, so that the first limiting portion 213 and the second limiting portion 2311 can cooperate to guide the connecting portion 231 to move relative to the locking sleeve 21 in the first direction X while limiting the rotation angle of the connecting portion 231, so as to achieve adjustment. The component 22 drives the connecting portion 231 to rotate relative to the lock sleeve 21 through the first gear 241 and the second gear 242, and can also drive the locking component 23 to move between the first position and the second position along the first direction X, so that the adjusting component 22 can drive the clamping portion 232 to engage with the lock base 300 while also driving the clamping portion 232 and the lock base 300 to abut against each other, so as to reduce the size of the gap between the clamping portion 232 and the lock base 300, which is beneficial to reduce vibration or impact between the locking mechanism 20 and the lock base 300.

[0231] According to some embodiments of the present application, please continue to refer to Figures 8 and 9, the first limiting portion 213 is a limiting groove 28 arranged on the inner circumferential surface of the locking sleeve 21, and the second limiting portion 2311 is a limiting protrusion 29 protruding from the outer circumferential surface of the connecting portion 231, and at least a portion of the limiting protrusion 29 is accommodated in the limiting groove 28.

[0232] Among them, the first limiting portion 213 is a limiting groove 28, and the second limiting portion 2311 is a limiting protrusion 29. By inserting the limiting protrusion 29 into the limiting groove 28, the movement trajectory of the limiting protrusion 29 will be restricted and guided by the limiting groove 28, so that the connecting portion 231 can achieve the limitation of the rotation angle and move between the first position and the second position along the first direction X under the cooperation of the first limiting portion 213 and the second limiting portion 2311.

[0233] For example, in Figures 8, 9 and 11, the limiting groove 28 provided on the lock sleeve 21 passes through the outer peripheral surface of the lock sleeve 21, so that the limiting groove 28 can be formed on the inner peripheral surface of the lock sleeve 21, which is conducive to reducing the manufacturing difficulty and facilitating the limiting protrusion 29 to be inserted into the limiting groove 28.

[0234] In this embodiment, the first limiting portion 213 and the second limiting portion 2311 are respectively provided with a limiting groove 28 on the inner circumferential surface of the lock sleeve 21 and a limiting protrusion 29 on the outer circumferential surface of the connecting portion 231. By inserting the limiting protrusion 29 into the limiting groove 28, the rotation angle of the connecting portion 231 can be limited under the restriction of the limiting groove 28, and the limiting protrusion 29 can realize the rotation of the connecting portion 231 relative to the lock sleeve 21 under the guidance of the limiting groove 28, and can also move relative to the lock sleeve 21 along the first direction X. The structure is simple, easy to implement, and has high stability.

[0235] In some embodiments, as shown in Figures 8, 9, and 11, the limiting groove 28 may include a first groove section 281, a second groove section 282, and a third groove section 283 connected in sequence. The first groove section 281 and the third groove section 283 both extend along the first direction X. The first groove section 281 and the third groove section 283 are arranged at intervals along the circumference of the connecting portion 231. The first groove section 281 and the third groove section 283 are arranged at intervals along the first direction X. Along the first direction X, the third groove section 283 is closer to the engaging portion 232 than the first groove section 281. When the locking member 23 is in the first position, the limiting protrusion 29 is located in the first groove section 281. When the locking member 23 is in the second position, the limiting protrusion 29 is located in the third groove section 283.

[0236] Among them, the first groove segment 281 and the third groove segment 283 are arranged at intervals along the circumference of the connecting portion 231, and the first groove segment 281 and the third groove segment 283 are arranged at intervals along the first direction X, that is, there is a distance between the first groove segment 281 and the third groove segment 283 of the limiting groove 28 in the first direction X, and there is also a distance in the circumferential direction of the connecting portion 231. It should be noted that, since the first groove segment 281 and the third groove segment 283 are arranged at intervals in the first direction X and in the circumferential direction of the connecting portion 231, the second groove segment 282 connecting the first groove segment 281 and the third groove segment 283 is a spiral structure surrounding the connecting portion 231, so that when the limiting protrusion 29 is located in the first groove segment 281 and the third groove segment 283, the connecting portion 231 can only move along the first direction X under the drive of the second gear 242, and when the limiting protrusion 29 is located in the second groove segment 282, the connecting portion 231 can be driven by the second gear 242 to move along the first direction X and rotate around the axis extending along the first direction X.

[0237] When the locking member 23 is in the first position, the limiting protrusion 29 is located in the first groove section 281, and when the locking member 23 is in the second position, the limiting protrusion 29 is located in the third groove section 283. That is to say, when the limiting protrusion 29 of the connecting portion 231 moves from the first groove section 281 to the third groove section 283, the locking member 23 can move from the first position to the second position.

[0238] Of course, the structure of the limiting groove 28 is not limited to this. In some embodiments, the limiting groove 28 can also be other structures. For example, the limiting groove 28 is a structure extending along the first direction X and having a wider width in the circumferential direction of the connecting portion 231, so that the limiting groove 28 has two opposite groove side surfaces in the circumferential direction of the connecting portion 231. The two groove side surfaces of the limiting groove 28 are arranged at intervals in the circumferential direction of the connecting portion 231, and the two groove side surfaces of the limiting groove 28 are used for the limiting protrusion 29 to abut. The limiting protrusion 29 is inserted in the limiting groove 28, and the limiting protrusion 29 is inserted into the limiting groove 28. The positioning protrusion 29 can move between the two groove side surfaces along the circumference of the connecting portion 231 to limit the rotation angle of the connecting portion 231, and when the positioning protrusion 29 abuts against the groove side surface of the limiting groove 28, the groove side surface of the limiting groove 28 can block the rotation of the connecting portion 231 to limit the rotation angle of the connecting portion 231, and the positioning protrusion 29 of the connecting portion 231 can move along the first direction X under the guidance of the groove side surface of the limiting groove 28 after being blocked by the groove side surface of the limiting groove 28, so that the connecting portion 231 can move along the first direction X.

[0239] In this embodiment, the first groove section 281 and the third groove section 283 of the limiting groove 28 are set to be structures extending along the first direction X, and the first groove section 281 and the third groove section 283 are arranged at intervals in the first direction X and the circumferential direction of the connecting portion 231, and the second groove section 282 connected between the first groove section 281 and the third groove section 283 is a spirally extended structure, so that when the limiting protrusion 29 of the connecting portion 231 is located in the first groove section 281 and the third groove section 283, it can only move along the first direction X following the extension direction of the first groove section 281 and the second groove section 282, and when the protrusion of the connecting portion 231 is located in the second groove section 282, it can rotate relative to the lock sleeve 21 along the extension direction of the second groove section 282 and can also move relative to the lock sleeve 21 along the first direction X, thereby achieving the limitation of the rotation angle of the locking member 23 and enabling movement between the first position and the second position along the first direction X. In addition, by setting the third groove section 283 to be closer to the clamping portion 232 than the first groove section 281 in the first direction X, when the protrusion is located in the first groove section 281, the clamping portion 232 can be clamped with the lock seat 300 and can be closer to the lock sleeve 21, so that the clamping portion 232 can abut against each other with the lock seat 300 in the first direction X.

[0240] According to some embodiments of the present application, referring to Figures 16, 17, and 18, Figure 16 is a schematic structural diagram of a locking mechanism 20 provided in some other embodiments of the present application, Figure 17 is an exploded structural diagram of a locking mechanism 20 provided in some other embodiments of the present application, and Figure 18 is a cross-sectional view of a locking mechanism 20 provided in some other embodiments of the present application. The adjusting member 22 is configured to simultaneously drive multiple locking members 23 to move relative to the lock sleeve 21, so that the multiple locking members 23 can switch between a locked state and an unlocked state at the same time. In other words, the adjusting member 22 is a structure that is transmission-connected to the multiple locking members 23, so that the adjusting member 22 can simultaneously drive the multiple locking members 23 to move relative to the lock sleeve 21, so that by rotating the adjusting member 22, the multiple locking members 23 can be driven to switch between a locked state and an unlocked state at the same time.

[0241] In this embodiment, the lock is configured such that the adjusting member 22 of the locking mechanism 20 is configured to be capable of simultaneously driving multiple locking members 23 to move relative to the locking sleeve 21, so as to realize that multiple locking members 23 are simultaneously driven to switch between the locked state and the unlocked state by one adjusting member 22, thereby enabling multiple locking members 23 to be locked or unlocked with the lock seat 300 at the same time. The locking mechanism 20 adopting this structure does not need to lock or unlock each locking member 23 through the adjusting member 22, thereby further reducing the locking action or unlocking action required by the locking mechanism 20 during use, which is conducive to further improving the operating efficiency of the locking mechanism 20 and further reducing the use cost of the locking mechanism 20.

[0242] According to some embodiments of the present application, as shown in Figures 17 and 18, the locking mechanism 20 may further include a transmission assembly 24. The transmission assembly 24 is disposed within the lock sleeve 21, and the adjustment member 22 is transmission-connected to the plurality of locking members 23 via the transmission assembly 24. The adjustment member 22 is rotatably disposed within the lock sleeve 21 about an axis extending along the first direction X. The adjustment member 22 is configured to simultaneously drive the plurality of locking members 23 to move relative to the lock sleeve 21 when rotating relative to the lock sleeve 21, thereby simultaneously switching the plurality of locking members 23 between a locked state and an unlocked state.

[0243] The transmission assembly 24 plays a role in transmitting and connecting the adjusting member 22 and the plurality of locking members 23 , so that the adjusting member 22 can move relative to the locking sleeve 21 through the transmission assembly 24 while the plurality of locking members 23 can move relative to the locking sleeve 21 .

[0244] The adjusting member 22 is transmission-connected to the plurality of locking members 23 via the transmission assembly 24 , that is, the adjusting member 22 is a structure in which the adjusting member 22 is transmission-connected to the plurality of locking members 23 simultaneously via the transmission assembly 24 .

[0245] The adjusting member 22 is rotatably disposed on the lock sleeve 21 about an axis extending in the first direction X. The adjusting member 22 is configured to simultaneously drive the multiple locking members 23 to move relative to the lock sleeve 21 when rotating relative to the lock sleeve 21, so that the multiple locking members 23 can simultaneously switch between a locked state and an unlocked state. In other words, the adjusting member 22 can rotate relative to the lock sleeve 21 about the axis extending in the first direction X. By rotating the adjusting member 22, the multiple locking members 23 can be simultaneously driven to move relative to the lock sleeve 21 via the transmission assembly 24, thereby achieving the simultaneous switching of the multiple locking members 23 between the locked state and the unlocked state. Of course, in other embodiments, the adjusting member 22 can also be configured to move relative to the lock sleeve 21 to achieve the simultaneous movement of the multiple locking members 23 relative to the lock sleeve 21.

[0246] In FIG. 18 , the adjusting member 22 is rotatably inserted into the lock sleeve 21 along the first direction X, and a portion of the adjusting member 22 passes through the lock sleeve 21 through the through hole 212 of the lock sleeve 21 along the first direction X, so that the portion of the adjusting member 22 extending out of the lock sleeve 21 can be operated by a user to drive the adjusting member 22 to rotate relative to the lock sleeve 21 to switch the state of the locking member 23.

[0247] In this embodiment, a transmission assembly 24 is provided in the lock sleeve 21 of the locking mechanism 20, and the adjusting member 22 is a structure that is transmission-connected to the multiple locking members 23 through the transmission assembly 24, so that the adjusting member 22 can be transmission-connected to the multiple locking members 23 at the same time, so that when the adjusting member 22 rotates around the axis extending along the first direction X, it can simultaneously drive the multiple locking members 23 to move relative to the lock sleeve 21, so that the adjusting member 22 can simultaneously drive the multiple locking members 23 to switch between the locked state and the unlocked state.

[0248] According to some embodiments of the present application, please continue to refer to Figures 17 and 18 , the transmission assembly 24 may include a moving member 243. The moving member 243 is movably disposed in the lock sleeve 21 along the first direction X. The moving member 243 is connected to the plurality of locking members 23, and the moving member 243 is connected to the adjustment member 22. The adjustment member 22 is configured to drive the moving member 243 to move along the first direction X when rotating relative to the lock sleeve 21, so that the moving member 243 simultaneously drives the plurality of locking members 23 to move relative to the lock sleeve 21, so that the plurality of locking members 23 can switch between the locked state and the unlocked state at the same time.

[0249] The movable member 243 is sleeved on the outer side of the adjusting member 22, so that the adjusting member 22 can drive the movable member 243 to move relative to the locking sleeve 21 in the first direction X when the adjusting member 22 rotates relative to the locking sleeve 21. It should be noted that the connection structure between the adjusting member 22 and the movable member 243 can be various. For example, the movable member 243 can be connected to the outer side of the adjusting member 22 by a threaded structure or a limiting structure, and the movable member 243 and the locking sleeve 21 are circumferentially locked, so that the rotation of the movable member 243 is restricted, and the adjusting member 22 can provide the movable member 243 with a feed force along the first direction X when rotating, thereby driving the movable member 243 to move along the first direction X. Of course, in other embodiments, the adjusting member 22 can also be movably provided on the locking sleeve 21 along the first direction X, so that the movable adjusting member 22 can directly drive the movable member 243 to move relative to the locking sleeve 21 along the first direction X.

[0250] 17 and 18 , the locking mechanism 20 is provided with two locking members 23, and correspondingly, the moving member 243 of the transmission assembly 24 is connected to both locking members 23. Of course, in other embodiments, the number of the locking members 23 may also be three, four, or five.

[0251] The adjusting member 22 is configured to drive the moving member 243 to move along the first direction X when it rotates relative to the lock sleeve 21, so that the moving member 243 simultaneously drives multiple locking members 23 to move relative to the lock sleeve 21. That is, by rotating the adjusting member 22 relative to the lock sleeve 21, the moving member 243 can be driven to move in the first direction X relative to the lock sleeve 21, so that the moving member 243 can simultaneously drive multiple locking members 23 to move relative to the lock sleeve 21, so that multiple locking members 23 can be switched between the locked state and the unlocked state at the same time, thereby realizing that the adjusting member 22 can simultaneously drive multiple locking members 23 to switch between the locked state and the unlocked state.

[0252] It should be noted that the connection structure between the moving member 243 and the locking member 23 can also be various. For example, the locking member 23 and the locking sleeve 21 are axially locked along the first direction X, and the locking member 23 is rotatably connected to the moving member 243 around an axis extending along the first direction X. A limiting structure is provided between the moving member 243 and the locking member 23. For example, the limiting structure includes a protrusion provided on the moving member 243 and a spiral guide groove provided on the outer peripheral surface of the locking member 23. The protrusion is inserted into the spiral guide groove, so that when the moving member 243 moves along the first direction X, it can drive the locking member 23 to rotate relative to the locking sleeve 21 around the axis extending along the first direction X, so as to realize the movement of the locking member 23 relative to the locking sleeve 21. For example, in FIG18 , the movable member 243 is sleeved on the outer side of the locking member 23 , the locking member 23 is rotatably connected to the movable member 243 , and the locking member 23 and the movable member 243 are axially locked along the first direction X, so that the movement of the movable member 243 along the first direction X can drive the locking member 23 to move relative to the lock sleeve 21 along the first direction X, thereby achieving movement of the locking member 23 relative to the lock sleeve 21. Of course, in this embodiment, a limiting structure can also be provided between the locking member 23 and the lock sleeve 21 , so that when the movable member 243 drives the locking member 23 to move along the first direction X, the limiting structure guides the locking member 23 to rotate relative to the lock sleeve 21 around an axis extending along the first direction X.

[0253] In this embodiment, the transmission assembly 24 is provided with a moving member 243, which is movably arranged in the lock sleeve 21 along the first direction X, and the moving member 243 is connected to the adjusting member 22 and the multiple locking members 23, so that when the adjusting member 22 rotates relative to the lock sleeve 21, it can drive the moving member 243 to move along the first direction X, thereby driving the multiple locking members 23 to move relative to the lock sleeve 21, thereby realizing that the adjusting member 22 can simultaneously drive the multiple locking members 23 to switch between the locked state and the unlocked state through the transmission assembly 24. The structure is simple and easy to implement.

[0254] In some embodiments, as shown in FIG. 17 and FIG. 18 , the moving member 243 is circumferentially locked with the locking sleeve 21 , and the moving member 243 is screwed to the outer side of the adjusting member 22 .

[0255] The moving member 243 is circumferentially locked with the locking sleeve 21 , that is, the moving member 243 cannot rotate relative to the locking sleeve 21 and can only move along the first direction X relative to the locking sleeve 21 .

[0256] The moving part 243 is screwed to the outside of the adjusting part 22, that is, the moving part 243 is sleeved on the outside of the adjusting part 22, and the moving part 243 is provided with an internal thread. Correspondingly, the outer peripheral surface of the adjusting part 22 is provided with an external thread, so that the adjusting part 22 can be connected to the moving part 243 through a threaded structure.

[0257] For example, in Figures 17 and 18, the adjusting member 22 includes a main body section 224 and a guide section 223 arranged along the first direction X, the guide section 223 is connected to one end of the main body section 224 in the first direction X, and the moving member 243 is sleeved and screwed to the outer side of the main body section 224.

[0258] Optionally, a third limiting portion 2241 is further provided on the outer peripheral surface of the main section 224 of the adjusting member 22, and the third limiting portion 2241 protrudes from the outer peripheral surface of the main section 224, and the third limiting portion 2241 is located on the end of the main section 224 away from the guide section 223 in the first direction X, so that the moving member 243 is connected between the third limiting portion 2241 and the guide section 223 of the adjusting member 22 in the first direction X, and the third limiting portion 2241 is used for the moving member 243 to abut against in the first direction X to limit the moving member 243 from separating from the main section 224.

[0259] In this embodiment, the moving member 243 is a structure that is circumferentially locked with the locking sleeve 21, and the moving member 243 is screwed to the outer side of the adjusting member 22. Since the rotation of the moving member 243 relative to the locking sleeve 21 is restricted, the adjusting member 22 can provide a feed force to drive the moving member 243 to move along the first direction X when it rotates relative to the locking sleeve 21, so that the adjusting member 22 can drive the moving member 243 to move along the first direction X when it rotates relative to the locking sleeve 21. The structure is simple and easy to assemble.

[0260] According to some embodiments of the present application, as shown in Figures 17 and 18, the movable member 243 may include a movable portion 2431 and two limiting members 2432. The movable portion 2431 is movably mounted on the outer side of the adjusting member 22 along the first direction X. The movable portion 2431 is connected to a plurality of locking members 23. The two limiting members 2432 are circumferentially locked with the locking sleeve 21. The two limiting members 2432 are both screwed onto the outer side of the adjusting member 22 and are located on both sides of the movable portion 2431 in the first direction X.

[0261] The movable portion 2431 and the limiting member 2432 are both connected to the main section 224 of the adjusting member 22. The movable portion 2431 is movably mounted on the outer side of the adjusting member 22 along the first direction X. The movable portion 2431 is circumferentially locked with the locking sleeve 21, so that the movable portion 2431 cannot rotate relative to the locking sleeve 21 and can only move relative to the locking sleeve 21 along the first direction X on the adjusting member 22.

[0262] The two limiting members 2432 are circumferentially locked with the locking sleeve 21 , that is, the two limiting members 2432 cannot rotate relative to the locking sleeve 21 and can only move relative to the locking sleeve 21 along the first direction X on the adjusting member 22 .

[0263] The two limiting members 2432 are both screwed to the outside of the adjusting member 22, and are respectively located on both sides of the movable portion 2431 in the first direction X. That is, the movable portion 2431 is located between the two limiting members 2432 in the first direction X, so that the two limiting members 2432 are a structure that cooperates to clamp the movable portion 2431 in the first direction X, and the limiting members 2432 are provided with internal threads, and the outer peripheral surface of the main body section 224 of the adjusting member 22 is provided with external threads, so that the two limiting members 2432 can be threadedly connected to the adjusting member 22. It should be noted that since the rotation of the limit member 2432 relative to the locking sleeve 21 is restricted, the adjusting member 22 can provide a feed force for the two limit members 2432 to move along the first direction X when it rotates relative to the locking sleeve 21, so that the two limit members 2432 can move relative to the locking sleeve 21 along the first direction X when the adjusting member 22 rotates relative to the locking sleeve 21, so as to further drive the moving part 2431 to move relative to the locking sleeve 21 along the first direction X, thereby simultaneously driving multiple locking members 23 to move relative to the locking sleeve 21 through the moving part 2431.

[0264] It should be noted that, in some embodiments, the moving part 2431 and the two limiting parts 2432 of the moving part 243 can also be an integral structure, that is, the moving part 2431 and the two limiting parts 2432 are an integrated structure, so that the moving part 243 is a structure screwed to the outside of the main section 224 of the adjusting part 22, and the moving part 243 is connected to multiple locking parts 23.

[0265] In this embodiment, the moving member 243 is provided with a moving portion 2431 and two limiting members 2432. The moving portion 2431 is movably sleeved on the outer side of the adjusting member 22 along the first direction X, and the moving portion 2431 is connected to the multiple locking members 23. By screwing the two limiting members 2432 to the outer side of the adjusting member 22, and respectively arranging the two limiting members 2432 on both sides of the moving portion 2431 in the first direction X, when the adjusting member 22 rotates relative to the locking sleeve 21, the two limiting members 2432 can be driven to move along the first direction X, so that the moving portion 2431 is further driven to move along the first direction X under the action of the two limiting members 2432, thereby The movable part 2431 can be used to drive multiple locking members 23 to move relative to the lock sleeve 21. The structure is simple and easy to assemble, and the force exerted by the locking member 23 on the movable part 2431 will not directly act on the adjusting member 22, so that the force applied by the locking member 23 to the movable part 2431 is transmitted to the adjusting member 22 through the limit member 2432. Therefore, when slippage or damage occurs between the limit member 2432 and the adjusting member 22, only the limit member 2432 needs to be replaced, and there is no need to replace the entire movable member 243, so that the locking mechanism 20 can be maintained in the later stage, and the later maintenance cost of the locking mechanism 20 can be reduced.

[0266] According to some embodiments of the present application, referring to Figures 17 and 18, and further referring to Figure 19, which is a partial enlarged view of point B of the locking mechanism 20 shown in Figure 18, the locking mechanism 20 may further include a first clutch member 25 and a second clutch member 26. The first clutch member 25 is disposed on the lock sleeve 21, and the second clutch member 26 is disposed on the adjustment member 22. The first clutch member 25 and the second clutch member 26 are configured to: restrict the adjustment member 22 from rotating relative to the lock sleeve 21 when engaged with each other; and allow the adjustment member 22 to rotate relative to the lock sleeve 21 when disengaged from each other.

[0267] Among them, the first clutch 25 and the second clutch 26 are used to selectively lock the adjusting member 22 and the locking sleeve 21 to limit the adjusting member 22 from rotating relative to the locking sleeve 21. That is, the first clutch 25 and the second clutch 26 can selectively lock or unlock the adjusting member 22 and the locking sleeve 21. When the first clutch 25 and the second clutch 26 lock the adjusting member 22 and the locking sleeve 21, the adjusting member 22 cannot rotate relative to the locking sleeve 21, thereby limiting the moving member 243 from moving relative to the locking sleeve 21 along the first direction X. When the first clutch 25 and the second clutch 26 unlock the adjusting member 22 and the locking sleeve 21, the adjusting member 22 can rotate relative to the locking sleeve 21, thereby driving the moving member 243 to move relative to the locking sleeve 21 along the first direction X.

[0268] The first clutch member 25 and the second clutch member 26 can restrict the adjustment member 22 from rotating relative to the lock sleeve 21 when they are engaged with each other. Conversely, when the first clutch member 25 and the second clutch member 26 are disengaged from each other, the adjustment member 22 can be allowed to rotate relative to the lock sleeve 21. Optionally, the structures of the first clutch 25 and the second clutch 26 can be various. For example, the first clutch 25 can be a structure fixed to the inner side of the lock sleeve 21. Correspondingly, the second clutch 26 is movably arranged on the outer side of the adjusting member 22 along the first direction X and is circumferentially locked with the adjusting member 22. That is, the second clutch 26 can move relative to the adjusting member 22 along the first direction X but cannot rotate circumferentially relative to the adjusting member 22, so that when the second clutch 26 moves along the first direction X to engage with the first clutch 25, the first clutch 25 and the second clutch 26 can cooperate to limit the rotation of the adjusting member 22 relative to the lock sleeve 21. Conversely, when the first clutch 25 and the second clutch 26 are disengaged from each other, the adjusting member 22 can be allowed to rotate relative to the lock sleeve 21. Of course, the structure of the locking mechanism 20 is not limited to this. In other embodiments, the locking mechanism 20 can also be other structures. For example, the first clutch member 25 can also be a structure that is movably arranged in the lock sleeve 21 along the first direction X and is circumferentially locked with the lock sleeve 21. Correspondingly, the second clutch member 26 is fixedly sleeved on the outside of the adjusting member 22. It can also be that the first clutch member 25 is fixed in the lock sleeve 21, and the second clutch member 26 is fixedly sleeved on the outside of the adjusting member 22, and the adjusting member 22 is movably arranged in the lock sleeve 21 along the first direction X, so that when the adjusting member 22 moves along the first direction X, it can drive the second clutch member 26 to engage with or disengage from the first clutch member 25.

[0269] Of course, the structure of the locking mechanism 20 is not limited to this. In other embodiments, the locking mechanism 20 can also have other structures. For example, the locking mechanism 20 does not have the first clutch member 25 and the second clutch member 26. The locking mechanism 20 includes a bolt threaded on the locking sleeve 21. When the bolt is tightened, the bolt can abut against the adjusting member 22 to limit the adjusting member 22 from rotating relative to the locking sleeve 21. When the bolt is loosened, the bolt can separate from the adjusting member 22 to allow the adjusting member 22 to rotate relative to the locking sleeve 21, thereby achieving selective locking of the adjusting member 22 and the locking sleeve 21.

[0270] In this embodiment, the locking mechanism 20 is further provided with a first clutch member 25 and a second clutch member 26 that can be engaged with or disengaged from each other, and the first clutch member 25 and the second clutch member 26 are respectively provided on the lock sleeve 21 and the adjusting member 22, so that the adjusting member 22 can be restricted from rotating relative to the lock sleeve 21 by engaging with the first clutch member 25 and the second clutch member 26, and the adjusting member 22 can be allowed to rotate relative to the lock sleeve 21 after the first clutch member 25 and the second clutch member 26 are disengaged from each other, so as to realize the function of the first clutch member 25 and the second clutch member 26 selectively locking the adjusting member 22 and the lock sleeve 21, thereby alleviating the phenomenon of the engagement failure of the locking member 23 and the lock seat 300 caused by the erroneous rotation of the adjusting member 22, thereby improving the locking effect between the locking member 23 and the lock seat 300, and facilitating the stability and reliability of the mutual locking between the locking mechanism 20 and the lock seat 300.

[0271] In some embodiments, referring to Figures 17, 18, and 19, the first clutch member 25 and the second clutch member 26 are arranged along the first direction X. The first clutch member 25 is fixed to the locking sleeve 21, the second clutch member 26 is circumferentially locked with the adjusting member 22, and the second clutch member 26 is movably disposed on the adjusting member 22 along the first direction X, so that the second clutch member 26 can engage with or disengage from the first clutch member 25.

[0272] The first clutch 25 is fixed to the inner side of the lock sleeve 21 , and the fixed connection structure between the first clutch 25 and the lock sleeve 21 can be various. For example, the first clutch 25 can be fixedly connected to the lock sleeve 21 by welding, bonding or clamping.

[0273] For example, referring to Figures 18 and 19, and further referring to Figure 20, Figure 20 is a cross-sectional view of a lock sleeve 21 of a locking mechanism 20 provided in some other embodiments of the present application. A through hole 212 for the adjustment member 22 to pass through is provided at one end of the lock sleeve 21 in the first direction X, and the first clutch member 25 is screwed onto the wall surface of the through hole 212. That is, an external thread is formed on the outer peripheral surface of the first clutch member 25, and an internal thread is formed on the wall surface of the through hole 212. The external thread of the first clutch member 25 cooperates with the internal thread formed on the wall surface of the through hole 212, so that the first clutch member 25 is screwed into the through hole 212 of the lock sleeve 21.

[0274] The second clutch member 26 is circumferentially locked with the adjusting member 22 and is movably provided on the adjusting member 22 along the first direction X. That is, the second clutch member 26 can move relative to the adjusting member 22 along the first direction X but cannot rotate circumferentially relative to the adjusting member 22, so that the second clutch member 26 can engage with or disengage from the first clutch member 25 when moving along the first direction X.

[0275] For example, referring to Figures 17, 18, and 19, and further to Figures 21 and 22, Figure 21 is a schematic structural diagram of the first clutch member 25 of the locking mechanism 20 provided in some other embodiments of the present application, and Figure 22 is a schematic structural diagram of the second clutch member 26 of the locking mechanism 20 provided in some other embodiments of the present application. The adjustment member 22 includes a main body section 224 and a guide section 223 arranged in sequence and connected along a first direction X. The guide section 223 is arranged along the first direction X through the through hole 212 of the locking sleeve 21 and extends out of the locking sleeve 21. The first clutch member 25 is provided with a first hole 251 for the guide section 223 to pass through. The first hole 251 extends through both ends of the first clutch member 25 along the first direction X, and a gap is set between the hole wall surface of the first hole 251 and the outer peripheral surface of the guide section 223. The moving member 243 is connected to the main section 224 of the adjusting member 22 . The second clutch member 26 is movably mounted on the outer side of the guide section 223 of the adjusting member 22 along the first direction X. The second clutch member 26 and the guide section 223 of the adjusting member 22 are circumferentially locked.

[0276] The second clutch member 26 is provided with a second hole 261 for inserting the guide section 223 of the adjusting member 22, so that the second clutch member 26 is movably sleeved on the outer side of the guide section 223 of the adjusting member 22 along the first direction X. Optionally, the circumferential locking structure between the second clutch member 26 and the adjusting member 22 can be various. A circumferential limiting structure, such as a spline and a spline groove, can be provided between the second clutch member 26 and the guide section 223 of the adjusting member 22. Alternatively, the hole wall surface of the second hole 261 of the second clutch member 26 and the outer circumferential surface of the guide section 223 of the adjusting member 22 can be mutually matched, and the cross-section of the hole wall surface of the second hole 261 of the second clutch member 26 perpendicular to the first direction X is a polygon.

[0277] In this embodiment, the first clutch member 25 and the second clutch member 26 are arranged along the first direction X, and the second clutch member 26 is movably provided on the adjusting member 22 along the first direction X. By fixing the first clutch member 25 to the lock sleeve 21 and configuring the second clutch member 26 to be circumferentially locked with the adjusting member 22, when the second clutch member 26 moves relative to the adjusting member 22 along the first direction X, the second clutch member 26 and the first clutch member 25 can be engaged or disengaged, thereby restricting the adjusting member 22 from rotating relative to the lock sleeve 21 or allowing the adjusting member 22 to rotate relative to the lock sleeve 21. The structure is simple and easy to operate and implement.

[0278] According to some embodiments of the present application, as shown in Figures 17, 18, and 19, the locking mechanism 20 may further include an elastic member 27. The elastic member 27 is disposed between the lock sleeve 21 and the second clutch member 26. The elastic member 27 is configured to drive the second clutch member 26 to move along the first direction X toward the first clutch member 25, so that the second clutch member 26 engages with the first clutch member 25.

[0279] Among them, the elastic member 27 is arranged between the lock sleeve 21 and the second clutch member 26, so that the elastic member 27 can provide elastic force for the second clutch member 26, so that the second clutch member 26 has a tendency to move in the first direction X toward the direction close to the first clutch member 25. Therefore, in actual use, it is only necessary to overcome the elastic force of the elastic member 27 and push the second clutch member 26 to disengage from the first clutch member 25 to drive the adjusting member 22 to rotate relative to the lock sleeve 21, so as to drive the multiple locking members 23 to switch between the locked state and the unlocked state at the same time through the transmission assembly 24. After the state switching of the multiple locking members 23 is completed, it is only necessary to cancel the force pushing the adjusting member 22 to make the adjusting member 22 reset under the elastic force of the elastic member 27, so that the second clutch member 26 and the first clutch member 25 are close to each other and engaged, so as to realize the rotation restriction function between the adjusting member 22 and the lock sleeve 21.

[0280] Alternatively, the elastic member 27 may have various structures. For example, the elastic member 27 may be a spring, a spring sheet, or elastic rubber disposed between the lock sleeve 21 and the second clutch member 26. For example, in FIG18 , the elastic member 27 is a spring, which is sleeved on the outside of the guide section 223 of the adjustment member 22.

[0281] In this embodiment, the locking mechanism 20 is further provided with an elastic member 27, which is arranged between the lock sleeve 21 and the second clutch member 26. The elastic member 27 can apply a force to the second clutch member 26 along the first direction X toward the first clutch member 25, so that the first clutch member 25 can be engaged with the second clutch member 26. The locking mechanism 20 with such a structure can, on the one hand, further improve the stability of the mutual engagement between the first clutch member 25 and the second clutch member 26, thereby reducing the phenomenon of accidental disengagement of the first clutch member 25 and the second clutch member 26. On the other hand, after the second clutch member 26 and the first clutch member 25 are disengaged from each other, the elastic member 27 can realize the automatic reset and engagement of the second clutch member 26 with the first clutch member 25, without manual intervention, which is convenient for operation and use.

[0282] In some embodiments, referring to Figures 17, 18, and 19, the adjustment member 22 may include a main body section 224 and a guide section 223. The guide section 223 is protruding from one end of the main body section 224 along the first direction X. The movable member 243 is connected to the main body section 224. The second clutch member 26 is movably sleeved on the outer side of the guide section 223 along the first direction X. The elastic member 27 is sleeved on the outer side of the guide section 223, and the two ends of the elastic member 27 in the first direction X respectively abut against the locking sleeve 21 and the second clutch member 26.

[0283] Among them, along the first direction X, the guide section 223 is protruded from one end of the main section 224, that is, the guide section 223 is a structure connected to one end of the main section 224 in the first direction X, and the outer diameter of the main section 224 is larger than the outer diameter of the guide section 223, so that the guide section 223 is protruded from one end of the main section 224.

[0284] The elastic member 27 is sleeved on the outside of the guide section 223, and the two ends of the elastic member 27 in the first direction X respectively abut against the lock sleeve 21 and the second clutch member 26. That is, the elastic member 27 is a structure sleeved on the outside of the guide section 223 of the adjusting member 22, and the elastic member 27 is compressed between the lock sleeve 21 and the second clutch member 26 in the first direction X, so that the two ends of the elastic member 27 can respectively abut against the lock sleeve 21 and the second clutch member 26, so that the elastic member 27 can provide elastic force to the second clutch member 26 along the first direction X, so as to drive the second clutch member 26 to move in the first direction X toward the first clutch member 25.

[0285] It should be noted that the elastic member 27 and the lock sleeve 21 can be in direct contact or indirect contact via other blocks or gaskets. Similarly, the elastic member 27 and the second clutch member 26 can be in direct contact or indirect contact via other blocks or gaskets.

[0286] In this embodiment, the adjusting member 22 is provided with a main body section 224 and a guide section 223, and the guide section 223 is protruded at one end of the main body section 224 in the first direction X. By connecting the moving member 243 to the main body section 224 of the adjusting member 22, and sleeve-mounting the second clutch member 26 and the elastic member 27 on the guide section 223 of the adjusting member 22, so that the two ends of the elastic member 27 can respectively abut against the lock sleeve 21 and the second clutch member 26, the locking mechanism 20 with such a structure can reduce the movement of the moving member 243 and the second clutch member 26 and the moving member 243. The interference between the movable member 243 and the elastic member 27 facilitates assembly and facilitates the elastic member 27 to apply elastic force to the second clutch member 26, so that the elastic member 27 drives the second clutch member 26 to move along the first direction X toward the first clutch member 25. On the other hand, the guide section 223 can play a certain guiding role on the elastic member 27, so as to achieve stable compression of the elastic member 27 along the first direction X, which is conducive to alleviating radial deformation or bending of the elastic member 27, thereby improving the stability and reliability of the elastic member 27.

[0287] According to some embodiments of the present application, as shown in Figures 17, 18, 19, and 22, the adjusting member 22 has a guide section 223, and the second clutch member 26 is movably sleeved on the outer side of the guide section 223 along the first direction X. The cross-section of the guide section 223 perpendicular to the first direction X is polygonal, and the outer circumferential surface of the guide section 223 is aligned with the inner circumferential surface of the second clutch member 26 to achieve circumferential locking between the second clutch member 26 and the adjusting member 22.

[0288] Among them, the guide section 223 is connected to one end of the main section 224 of the adjusting member 22 away from the clamping portion 232 in the first direction X, the first clutch member 25 is fixed in the sleeve and is arranged around the guide section 223 of the adjusting member 22, and the second clutch member 26 is movably sleeved on the outer side of the guide section 223 of the adjusting member 22 along the first direction X, so that the second clutch member 26 can move relative to the adjusting member 22 along the first direction X, so that the second clutch member 26 can be clamped or separated from the first clutch member 25.

[0289] The second clutch member 26 is provided with a second hole 261 for inserting the guide section 223 of the adjustment member 22, so that the second clutch member 26 can be sleeved on the outside of the guide section 223. The cross-section of the guide section 223 perpendicular to the first direction X is polygonal, and the outer circumference of the guide section 223 is aligned with the inner circumference of the second clutch member 26. In other words, the cross-section of the guide section 223 perpendicular to the first direction X is the same as the cross-section of the second hole 261 perpendicular to the first direction X, and both are polygonal. This allows the outer circumference of the guide section 223 to be aligned with the wall surface of the second hole 261 after the guide section 223 is inserted into the second hole 261 of the second clutch member 26.

[0290] For example, in Figures 17 and 22, the cross-section of the guide segment 223 perpendicular to the first direction X and the cross-section of the second hole 261 perpendicular to the first direction X are both regular hexagons. Of course, in other embodiments, the cross-section of the guide segment 223 perpendicular to the first direction X and the cross-section of the second hole 261 perpendicular to the first direction X can also be triangular, rectangular, pentagonal or heptagonal, etc.

[0291] It should be noted that, in other embodiments, the structure of the circumferential locking of the second clutch member 26 and the guide section 223 of the adjusting member 22 can be various. For example, a spline extending along the first direction X can be convexly provided on the outer peripheral surface of the guide section 223, and correspondingly, a spline groove that cooperates with the spline is provided on the wall surface of the second hole 261 of the second clutch member 26 to achieve circumferential locking of the second clutch member 26 and the guide section 223 of the adjusting member 22.

[0292] In this embodiment, the guide section 223 of the adjusting member 22 is configured to have a polygonal cross-section perpendicular to the first direction X, the second clutch member 26 is movably sleeved on the outside of the guide section 223 along the first direction X, and the inner circumferential surface of the second clutch member 26 is configured to fit with the outer circumferential surface of the guide section 223. As a result, the projection shape of the inner circumferential surface of the second clutch member 26 in the first direction X is the same as the cross-section shape of the guide section 223 perpendicular to the first direction X, and both are polygonal. This ensures that the second clutch member 26 can be circumferentially locked with the adjusting member 22 but can move relative to the adjusting member 22 along the first direction X. This results in a simple structure and facilitates manufacturing and assembly.

[0293] According to some embodiments of the present application, referring to Figures 17, 18, 21 and 22, along the first direction X, a first tooth-shaped portion 252 is provided at one end of the first clutch member 25 facing the second clutch member 26, and a second tooth-shaped portion 262 is provided at one end of the second clutch member 26 facing the first clutch member 25. The second tooth-shaped portion 262 is used to engage with the first tooth-shaped portion 252 to achieve a snap-fit ​​connection between the second clutch member 26 and the first clutch member 25.

[0294] The first toothed portion 252 is a toothed structure provided on the end of the first clutch member 25 facing the second clutch member 26 in the first direction X. The multiple teeth of the first toothed portion 252 are arranged circumferentially of the first clutch member 25, and each tooth extends radially of the first clutch member 25, so that the first toothed portion 252 is provided around the second assembly section 222 of the adjusting member 22. The second toothed portion 262 is a toothed structure provided on the end of the second clutch member 26 facing the first clutch member 25 in the first direction X. The multiple teeth of the second toothed portion 262 are arranged circumferentially of the second clutch member 26, and each tooth extends radially of the second clutch member 26, so that the second toothed portion 262 is provided around the second assembly section 222 of the adjusting member 22. When the adjusting member 22 drives the second clutch member 26 to move along the first direction X and approaches the first clutch member 25, the second tooth-shaped portion 262 and the first tooth-shaped portion 252 can engage with each other, thereby realizing the mutual engagement of the second clutch member 26 and the first clutch member 25 to restrict the adjusting member 22 from rotating relative to the locking sleeve 21. Conversely, after the first tooth-shaped portion 252 and the second tooth-shaped portion 262 are disengaged from each other, the adjusting member 22 can be allowed to rotate relative to the locking sleeve 21.

[0295] It should be noted that, in other embodiments, the first clutch member 25 and the second clutch member 26 may also be other structures. For example, a limiting hole is provided at one end of the first clutch member 25 facing the second clutch member 26 in the first direction X, and a latch is provided at one end of the second clutch member 26 facing the first clutch member 25 in the first direction X. When the adjusting member 22 drives the second clutch member 26 to move along the first direction X and approaches the first clutch member 25, the latch can be inserted into the limiting hole to achieve mutual engagement between the second clutch member 26 and the first clutch member 25, thereby limiting the rotation of the adjusting member 22 relative to the lock sleeve 21.

[0296] In this embodiment, a first toothed portion 252 is provided on the end of the first clutch member 25 facing the second clutch member 26, and a second toothed portion 262 is correspondingly provided on the end of the second clutch member 26 facing the first clutch member 25. This allows the second toothed portion 262 to engage or disengage with the first toothed portion 252 when the second clutch member 26 moves in the first direction X, thereby achieving a snap-fitting or disengaging relationship between the second clutch member 26 and the first clutch member 25. This allows the first and second clutch members 25, 26 to cooperate in limiting the rotation of the adjustment member 22 relative to the lock sleeve 21 when the first and second toothed portions 252, 262 are engaged with each other. This structure is simple and easy to implement. Furthermore, the provision of the first and second toothed portions 252, 262 on the first and second clutch members 25, 26, respectively, facilitates the snap-fitting or disengaging relationship between the first and second clutch members 25, 26, thereby reducing the difficulty of engaging or disengaging the first and second clutch members 25, 26.

[0297] According to some embodiments of the present application, as shown in Figures 16, 17, and 18, the locking member 23 may include a connecting portion 231 and a clamping portion 232. The connecting portion 231 extends along the first direction X and is inserted into the lock sleeve 21. The connecting portion 231 is rotatably connected to the movable member 243 around an axis extending along the first direction X. The clamping portion 232 is located outside the lock sleeve 21 and is connected to an end of the connecting portion 231 away from the lock sleeve 21. The clamping portion 232 protrudes from the outer circumferential surface of the connecting portion 231 along its extension direction. The clamping portion 232 is used to clamp with the lock seat 300. The extension direction of the clamping portion 232 is perpendicular to the first direction X. The moving member 243 is configured to simultaneously drive the connecting portions 231 of multiple locking members 23 to rotate when it moves relative to the lock sleeve 21 along the first direction X, so that the clamping portions 232 of the multiple locking members 23 are all clamped or unclamped with the lock seat 300, so that the multiple locking members 23 can switch between the locked state and the unlocked state at the same time.

[0298] Among them, the connecting portion 231 of the locking member 23 is a columnar structure extending along the first direction X. Part of the connecting portion 231 is inserted into the lock sleeve 21 along the first direction X. The connecting portion 231 is inserted into the assembly hole 211 of the lock sleeve 21 along the first direction X, and one end of the connecting portion 231 extends out of the lock sleeve 21 through the assembly hole 211 and is connected to the clamping portion 232.

[0299] The connecting portion 231 is rotatably connected to the moving member 243 around an axis extending along the first direction X. That is, the connecting portion 231 is connected to the moving member 243 and can rotate around the axis extending along the first direction X relative to the moving member 243.

[0300] The clamping portion 232 is located outside the locking sleeve 21 and is connected to one end of the connecting portion 231 away from the locking sleeve 21, that is, the connecting portion 231 has a portion extending out of the locking sleeve 21 through the assembly hole 211 in the first direction X, and the clamping portion 232 is connected to one end of the portion of the connecting portion 231 extending out of the locking sleeve 21, so that the clamping portion 232 is arranged at an interval from the locking sleeve 21 along the first direction X.

[0301] The clamping portion 232 protrudes from the outer peripheral surface of the connecting portion 231 along its extension direction, that is, in the extension direction of the clamping portion 232, the clamping portion 232 extends beyond the outer peripheral surface of the connecting portion 231. For example, in Figure 18, the extension direction of the clamping portion 232 is perpendicular to the first direction X, so that the clamping portion 232 and the connecting portion 231 form a "T"-shaped structure. Of course, in other embodiments, the clamping portion 232 and the connecting portion 231 can also form an "L"-shaped structure.

[0302] The movable member 243 is configured to simultaneously drive the connecting portions 231 of multiple locking members 23 to rotate when it moves relative to the lock sleeve 21 along the first direction X, so that the clamping portions 232 of multiple locking members 23 are all engaged or released from the lock seat 300, so that the multiple locking members 23 can switch between the locked state and the unlocked state at the same time, that is, the adjusting member 22 can drive the movable member 243 to move along the first direction X when it rotates relative to the lock sleeve 21, so as to drive the connecting portions 231 of multiple locking members 23 to rotate around the axis extending along the first direction X, thereby changing the extension direction of the clamping portion 232 of each locking member 23, so that the clamping portion 232 can overlap the lock seat 300 or release the overlap from the lock seat 300, so that the clamping portion 232 can be engaged or released from the lock seat 300.

[0303] It should be noted that when the movable member 243 moves along the first direction X, it can drive the connecting portion 231 of the locking member 23 to rotate around the axis extending along the first direction X. The connection structure between the movable member 243 and the connecting portion 231 can be various. For example, the movable member 243 can be sleeved on the outside of the connecting portion 231, and the connecting portion 231 and the locking sleeve 21 are axially locked along the first direction X. The connecting portion 231 is rotatably connected to the movable member 243 around the axis extending along the first direction X. A limiting structure is provided between the movable member 243 and the connecting portion 231. For example, the limiting structure includes a protrusion provided on the movable member 243 and a spiral guide groove provided on the outer peripheral surface of the connecting portion 231. The protrusion is inserted into the spiral guide groove, so that when the movable member 243 moves along the first direction X, it can drive the connecting portion 231 to rotate around the axis extending along the first direction X relative to the locking sleeve 21. Of course, the moving part 243 can also be sleeved on the outside of the connecting part 231, the connecting part 231 can be rotatably connected to the moving part 243, and the connecting part 231 and the moving part 243 are axially locked along the first direction X, so that the moving part 243 moving along the first direction X can drive the locking part 23 to move relative to the lock sleeve 21 along the first direction X. Correspondingly, a limiting structure is provided between the connecting part 231 and the lock body. For example, the limiting structure includes a protrusion provided on the inner circumferential surface of the lock sleeve 21 and a spiral guide groove provided on the outer circumferential surface of the connecting part 231, and the protrusion is inserted into the spiral guide groove, so that the limiting structure guides the connecting part 231 to rotate relative to the lock sleeve 21 around the axis extending along the first direction X when the moving part 243 drives the connecting part 231 to move along the first direction X, so as to realize that the connecting part 231 can not only rotate relative to the lock sleeve 21 around the axis extending along the first direction X, but also move relative to the lock sleeve 21 along the first direction X.

[0304] The locking member 231 is provided with a connecting portion 231 and a clamping portion 232 connected to one end of the connecting portion 231, and the clamping portion 232 protrudes from the outer peripheral surface of the connecting portion 231 in its extension direction. By inserting the connecting portion 231 into the lock sleeve 21 along the first direction X and rotatably connected to the movable member 243 around an axis extending along the first direction X, when the adjusting member 22 rotates relative to the lock sleeve 21, the movable member 243 can be driven to move along the first direction X, thereby simultaneously driving the connecting portions 231 of the plurality of locking members 23 to rotate relative to the lock sleeve 21, so that the corresponding clamping portions 232 can rotate along the corresponding connecting portions 231, thereby achieving the change of the extension direction of the clamping portion 232 in a plane perpendicular to the first direction X, so that the clamping portions 232 of the plurality of locking members 23 can be simultaneously engaged with or disengaged from the lock seat 300 after rotation, thereby achieving the engagement or disengagement of the plurality of locking members 23 of the locking mechanism 20 with the lock seat 300 in the first direction X.

[0305] According to some embodiments of the present application, as shown in Figures 17, 18, and 20, the connecting portion 231 and the moving member 243 are axially locked along the first direction X. The locking sleeve 21 is provided with a first limiting portion 213, and the connecting portion 231 is provided with a second limiting portion 2311. The first limiting portion 213 and the second limiting portion 2311 are configured to cooperate and guide the connecting portion 231 to rotate about an axis extending along the first direction X when the moving member 243 drives the locking member 23 to move between the first position and the second position along the first direction X. When the locking member 23 is in the first position, the locking member 23 is in a locked state, so that the engaging portion 232 can be engaged with the lock base 300; when the locking member 23 is in the second position, the locking member 23 is in an unlocked state, so that the engaging portion 232 can be disengaged from the lock base 300.

[0306] The connecting portion 231 and the moving member 243 are axially locked along the first direction X, that is, the connecting portion 231 can rotate relative to the moving member 243 around an axis extending along the first direction X, but cannot move relative to the moving member 243 along the first direction X.

[0307] Optionally, the structures for axial locking of the connecting portion 231 and the moving part 243 along the first direction X can be various. For example, the moving part 243 can be sleeved on the outside of the connecting portion 231, and the connecting portion 231 can be rotatably arranged on the moving part 243. The outer peripheral surface of the connecting portion 231 is provided with an annular groove arranged along the circumference of the connecting portion 231. Correspondingly, the hole wall surface of the channel of the moving part 243 for the connecting portion 231 to be inserted is provided with an annular protrusion inserted into the annular groove, so that the connecting portion 231 can rotate relative to the moving part 243 around the axis extending along the first direction X and be axially locked with the moving part 243 along the first direction X. For example, referring to Figure 18 and further referring to Figure 23, Figure 23 is a cross-sectional view of the connecting portion 231 of the locking member 23 of the locking mechanism 20 provided in some other embodiments of the present application. The connecting portion 231 includes a first connecting segment 2312 and a second connecting segment 2313 arranged in sequence and connected along the first direction X. The first connecting segment 2312 is protruded from one end of the second connecting segment 2313 in the first direction X. The outer diameter of the first connecting segment 2312 is smaller than the outer diameter of the second connecting segment 2313. The clamping portion 232 is connected to one end of the first connecting segment 2312 away from the second connecting segment 2313 in the first direction X. The second limiting portion 2311 is arranged on the second connecting segment 2313, and the moving portion 2431 of the moving member 243 is sleeved on the outside of the first connecting segment 2312, and the first connecting segment 2312 can rotate relative to the moving portion 2431 around the axis extending along the first direction X. The outside of the first connecting segment 2312 is also sleeved with a fixing member 233. Along the first direction X, the second connecting segment 2313 and the fixing member 233 are respectively located on both sides of the moving portion 2431. The second connecting segment 2313 and the fixing member 233 are configured to cooperate to limit the movement of the moving portion 2431 relative to the connecting portion 231, so that the connecting portion 231 can rotate relative to the moving member 243 around the axis extending along the first direction X and be axially locked with the moving member 243 along the first direction X.

[0308] Illustratively, a snap ring 234 is sleeved on the outer circumference of the first connecting section 2312. The snap ring 234 is snapped onto the first connecting section 2312. The snap ring 234 is located on the side of the fixing member 233 facing away from the movable portion 2431 in the first direction X, thereby fixing the fixing member 233 between the movable portion 2431 and the snap ring 234. Of course, in other embodiments, the fixing member 233 may also be a structure directly fixed to the first connecting section 2312 of the connecting portion 231, for example, by welding, bonding, etc.

[0309] The first limiting portion 213 and the second limiting portion 2311 are configured to cooperate to guide the connecting portion 231 to rotate around the axis extending along the first direction X when the moving member 243 drives the locking member 23 to move between the first position and the second position along the first direction X. That is, when the adjusting member 22 drives the connecting portions 231 of the multiple locking members 23 to move relative to the lock sleeve 21 along the first direction X through the moving member 243, the first limiting portion 213 and the second limiting portion 2311 cooperate to guide the connecting portion 231 to rotate relative to the lock sleeve 21 around the axis extending along the first direction X, so that the locking member 23 has two end positions relative to the lock sleeve 21 in the first direction X, namely The first position and the second position, that is, the adjusting member 22 can drive the locking member 23 to move relative to the lock sleeve 21 along the first direction X through the moving member 243, and can also drive the locking member 23 to rotate relative to the lock sleeve 21 around the axis extending along the first direction X, so that when the connecting portion 231 drives the clamping portion 232 to rotate until the clamping portion 232 can engage with the side of the lock seat 300 away from the lock sleeve 21, the locking member 23 is in the first position. Correspondingly, when the locking member 23 moves to the second position, the projection of the clamping portion 232 in the first direction X is located in the lock hole 301 of the lock seat 300, so that the locking member 23 can be disengaged from the lock seat 300 along the first direction X.

[0310] Optionally, the number of the first limiting portion 213 and the second limiting portion 2311 provided between each locking member 23 and the locking sleeve 21 may be one or more. For example, in Figures 17 and 18, each locking member 23 is provided with a second limiting portion 2311, and correspondingly, the locking sleeve 21 is provided with a first limiting portion 213 corresponding to each locking member 23.

[0311] In this embodiment, the connecting portion 231 of the locking member 23 and the moving member 243 are axially locked in the first direction X, so that when the adjusting member 22 drives the moving member 243 to move along the first direction X, the moving member 243 can drive the connecting portion 231 to move along the first direction X, and the connecting portion 231 can rotate relative to the moving member 243, thereby providing the first limiting portion 213 and the second limiting portion 2311 on the locking sleeve 21 and the connecting portion 231 respectively, so that the first limiting portion 213 and the second limiting portion 2311 are locked. When the movable member 243 drives the connecting portion 231 to move along the first direction X, the movable member 243 can also cooperate with the guiding connecting portion 231 to rotate relative to the movable member 243, so that the adjusting member 22 can drive the engaging portion 232 of the locking member 23 to engage with the lock base 300 through the movable member 243, and can also drive the engaging portion 232 and the lock base 300 to abut against each other, so as to reduce the size of the gap between the engaging portion 232 and the lock base 300, which is beneficial to reduce the vibration or impact between the locking mechanism 20 and the lock base 300.

[0312] According to some embodiments of the present application, referring to Figures 18, 20 and 23, the first limiting portion 213 is a limiting protrusion 29 protruding from the inner circumference of the locking sleeve 21, and the second limiting portion 2311 is a limiting groove 28 provided on the outer circumference of the connecting portion 231, and at least a portion of the limiting protrusion 29 is accommodated in the limiting groove 28.

[0313] Among them, the first limiting portion 213 is a limiting protrusion 29, and the second limiting portion 2311 is a limiting groove 28. By inserting the limiting protrusion 29 into the limiting groove 28, when the connecting portion 231 moves along the first direction X under the drive of the moving member 243, the limiting protrusion 29 drives the connecting portion 231 to rotate relative to the locking sleeve 21 around the axis extending along the first direction X along the trajectory of the limiting groove 28, so that the locking member 23 moves between the first position and the second position along the first direction X while rotating relative to the locking sleeve 21 around the axis extending along the first direction X.

[0314] For example, referring to Figures 17 and 20, the limiting protrusion 29 is a screw connected to the locking sleeve 21, the screw is threaded onto the locking sleeve 21 and protrudes from the inner circumference of the locking sleeve 21, and one end of the screw extends to the inside of the locking sleeve 21 and is inserted into the limit.

[0315] For example, in Figure 23, the limiting groove 28 is arranged on the second connecting section 2313 of the connecting part 231, and a cavity 2313a is formed inside the second connecting section 2313, and the cavity 2313a passes through the end of the second connecting section 2313 away from the first connection along the first direction X. The limiting groove 28 is arranged on the outer peripheral surface of the second connecting section 2313, and along the radial direction of the connecting part 231, the limiting groove 28 passes through the hole wall surface of the cavity 2313a, so as to facilitate the setting of the limiting groove 28 on the second connecting section 2313, which is conducive to reducing the manufacturing difficulty and facilitating the insertion of the limiting protrusion 29.

[0316] It should be noted that, in other embodiments, the first limiting portion 213 may also be a limiting groove 28 provided on the inner circumferential surface of the lock sleeve 21. Correspondingly, the second limiting portion 2311 is a limiting protrusion 29 protruding from the outer circumferential surface of the connecting portion 231, and the limiting protrusion 29 is inserted into the limiting groove 28.

[0317] In this embodiment, the first limiting portion 213 and the second limiting portion 2311 are respectively a limiting protrusion 29 provided on the inner circumferential surface of the lock sleeve 21 and a limiting groove 28 on the outer circumferential surface of the connecting portion 231. By inserting the limiting protrusion 29 into the limiting groove 28, the connecting portion 231 can be guided by the cooperation of the limiting groove 28 and the limiting protrusion 29 to realize that the connecting portion 231 moves relative to the lock sleeve 21 along the first direction X while also being able to rotate relative to the lock sleeve 21, thereby being able to limit the rotation angle of the connecting portion 231 under the restriction of the limiting groove 28, and the limiting protrusion 29 can be guided by the limiting groove 28 to realize that the connecting portion 231 moves relative to the lock sleeve 21 along the first direction X while being able to rotate relative to the lock sleeve 21. The structure is simple, easy to implement, and has high stability.

[0318] In some embodiments, as shown in Figures 17, 18, and 23, the limiting groove 28 may include a first groove section 281, a second groove section 282, and a third groove section 283 connected in sequence. The first groove section 281 and the third groove section 283 both extend along the first direction X. The first groove section 281 and the third groove section 283 are arranged at intervals along the circumference of the connecting portion 231. The first groove section 281 and the third groove section 283 are arranged at intervals along the first direction X. Along the first direction X, the third groove section 283 is closer to the engaging portion 232 than the first groove section 281. When the locking member 23 is in the first position, the limiting protrusion 29 is located in the third groove section 283. When the locking member 23 is in the second position, the limiting protrusion 29 is located in the first groove section 281.

[0319] Among them, the first groove segment 281 and the third groove segment 283 are arranged at intervals along the circumference of the connecting portion 231, and the first groove segment 281 and the third groove segment 283 are arranged at intervals along the first direction X, that is, there is a distance between the first groove segment 281 and the third groove segment 283 of the limiting groove 28 in the first direction X, and there is also a distance in the circumferential direction of the connecting portion 231. It should be noted that, since the first groove segment 281 and the third groove segment 283 are arranged at intervals in the first direction X and in the circumferential direction of the connecting portion 231, the second groove segment 282 connecting the first groove segment 281 and the third groove segment 283 is a spiral structure surrounding the connecting portion 231, so that when the limiting protrusion 29 is located in the first groove segment 281 and the third groove segment 283, the connecting portion 231 can only move along the first direction X under the drive of the moving member 243, and when the limiting protrusion 29 is located in the second groove segment 282, the connecting portion 231 can be driven by the moving member 243 to move along the first direction X and rotate around the axis extending along the first direction X.

[0320] When the locking member 23 is in the first position, the limiting protrusion 29 is located in the third groove section 283. When the locking member 23 is in the second position, the limiting protrusion 29 is located in the first groove section 281. That is to say, when the limiting protrusion 29 of the connecting portion 231 moves from the first groove section 281 to the third groove section 283, the locking member 23 can move from the second position to the first position.

[0321] In this embodiment, the first groove section 281 and the third groove section 283 of the limiting groove 28 are configured to extend along the first direction X, and the first groove section 281 and the third groove section 283 are arranged at intervals in the first direction X and the circumferential direction of the connecting portion 231, so that the second groove section 282 connected between the first groove section 281 and the third groove section 283 is a spirally extended structure, so that when the limiting protrusion 29 of the locking sleeve 21 is located in the first groove section 281 and the third groove section 283, the connecting portion 231 can only be positioned between the limiting protrusion 29 and the first groove section 281 or the limiting protrusion 29 and the third groove section 283. The locking member 23 can move along the first direction X in cooperation with the third groove section 283, and when the limiting protrusion 29 of the lock sleeve 21 is located in the second groove section 282, the connecting portion 231 can simultaneously move relative to the lock sleeve 21 in the first direction X and rotate relative to the lock sleeve 21 under the cooperation of the limiting protrusion 29 and the second groove section 282, thereby enabling the connecting portion 231 to both move relative to the lock sleeve 21 in the first direction X and rotate relative to the lock sleeve 21, thereby enabling the locking member 23 to move between the first position and the second position in the first direction X and also rotate relative to the lock sleeve 21 between the locked state and the unlocked state. In addition, by arranging the third groove section 283 to be closer to the engaging portion 232 than the first groove section 281 in the first direction X, the engaging portion 232 can engage with the lock base 300 and move closer to the lock sleeve 21 when the protrusion is located in the third groove section 283, so that the engaging portion 232 and the lock base 300 can abut against each other in the first direction X.

[0322] According to some embodiments of the present application, as shown in Figures 7, 8, and 9, as well as Figures 16, 17, and 18, an adjusting member 22 is rotatably disposed on the lock sleeve 21 about an axis extending along a first direction X. The adjusting member 22 is configured to drive the plurality of locking members 23 to move relative to the lock sleeve 21 when rotating relative to the lock sleeve 21, thereby switching the locking members 23 between a locked state and an unlocked state. In other words, the adjusting member 22 is rotatable relative to the lock sleeve 21 about an axis extending along the first direction X, so that the locking members 23 can be switched between a locked state and an unlocked state by rotating the adjusting member 22. Of course, in some embodiments, the adjusting member 22 can also be configured to switch the locking members 23 between a locked state and an unlocked state by moving relative to the lock sleeve 21.

[0323] For example, the adjusting member 22 may be made of various materials, such as steel, aluminum, iron, aluminum alloy, or plastic.

[0324] In this embodiment, the adjusting member 22 is rotatably arranged in the lock sleeve 21 around an axis extending along the first direction X. By rotating the adjusting member 22, the locking member 23 can be driven to move relative to the lock sleeve 21, so that the locking member 23 can be engaged or disengaged with the lock seat 300. The locking mechanism 20 with this structure is convenient for subsequent operation. The locking mechanism 20 and the lock seat 300 can be locked or unlocked by simply rotating the adjusting member 22, which is beneficial to improving the operating efficiency and convenience of the locking mechanism 20.

[0325] In some embodiments, as shown in Figures 7, 8, 9, 16, 17, and 18, the locking member 23 may include a connecting portion 231 and a clamping portion 232. The connecting portion 231 extends along the first direction X and is inserted into the lock sleeve 21. The connecting portion 231 is in transmission connection with the adjusting member 22. The clamping portion 232 is located outside the lock sleeve 21 and is connected to the end of the connecting portion 231 away from the lock sleeve 21. The clamping portion 232 protrudes from the outer circumference of the connecting portion 231 along its extension direction. The clamping portion 232 is configured to engage with the lock base 300. The extension direction of the clamping portion 232 is perpendicular to the first direction X. The adjusting member 22 is configured to rotate relative to the lock sleeve 21 to drive the connecting portion 231 to rotate, thereby engaging or disengaging the clamping portion 232 with the lock base 300, thereby switching the locking member 23 between a locked state and an unlocked state.

[0326] In this embodiment, the locking member 23 is provided with a connecting portion 231 and a clamping portion 232 connected to one end of the connecting portion 231, and the clamping portion 232 protrudes from the outer peripheral surface of the connecting portion 231 in its extension direction. By inserting the connecting portion 231 into the lock sleeve 21 along the first direction X and transmittingly connecting it with the adjusting member 22, the adjusting member 22 can drive the connecting portion 231 to rotate when rotating, so that the clamping portion 232 can rotate with the connecting portion 231, thereby realizing that the extension direction of the clamping portion 232 is changed in a plane perpendicular to the first direction X, so that the clamping portion 232 can be clamped or released with the lock seat 300 after rotation, thereby realizing that the locking mechanism 20 can engage with or disengage with the lock seat 300 in the first direction X.

[0327] According to some embodiments of the present application, referring to Figures 8, 9 and 11 as well as Figures 17, 18 and 20, the clamping portion 232 and the locking sleeve 21 are arranged along the first direction X, and the locking sleeve 21 has a clamping surface 214 facing the clamping portion 232 in the first direction X, and the clamping surface 214 and the clamping portion 232 are configured to respectively abut against both sides of the lock seat 300 along the first direction X when the locking member 23 is in the locked state.

[0328] The connecting portion 231 of the locking member 23 extends out of the locking sleeve 21 along the first direction X through the assembly hole 211 of the locking sleeve 21, and the engaging portion 232 is connected to one end of the connecting portion 231 extending out of the locking sleeve 21 in the first direction X, so that the engaging portion 232 and the locking sleeve 21 are arranged along the first direction X. The engaging surface 214 is the end surface of the locking sleeve 21 facing the engaging portion 232 in the first direction X, and the assembly hole 211 passes through the engaging surface 214.

[0329] The locking surface 214 and the locking portion 232 are configured to respectively abut against both sides of the lock base 300 along the first direction X when the locking member 23 is in the locked state. That is to say, when the locking mechanism 20 is engaged with the lock base 300 along the first direction X through the locking member 23 and locked with each other, the locking portion 232 of the locking member 23 and the locking surface 214 of the lock sleeve 21 can respectively abut against both sides of the lock base 300 in the first direction X. It should be noted that the locking surface 214 and the locking portion 232 can be directly abutted against the lock base 300 or indirectly abutted against the lock base 300. For example, when the lock sleeve 21 is connected to the target part and the locking member 23 passes through the target part, the locking surface 214 is a structure that indirectly abuts against the lock base 300 through the target part to lock the target part on the lock base 300.

[0330] In this embodiment, the locking sleeve 21 has a clamping surface 214 facing the clamping portion 232 in the first direction X, and the clamping surface 214 and the clamping portion 232 of the locking member 23 can respectively abut against the two sides of the lock seat 300 along the first direction X when the locking member 23 is in the locked state, so that the locking mechanism 20 can clamp the lock seat 300 in the first direction X through the clamping portion 232 of the locking member 23 and the clamping surface 214 of the locking sleeve 21, which is beneficial to reduce the shaking phenomenon of the locking mechanism 20 during use, thereby improving the stability and reliability of the mutual locking between the locking mechanism 20 and the lock seat 300.

[0331] According to some embodiments of the present application, as shown in Figures 17, 18, and 19, the clamping portion 232 and the connecting portion 231 are integrally formed. In other words, the clamping portion 232 and the connecting portion 231 are an integral structure, and the clamping portion 232 and the connecting portion 231 are made by an integral molding process, such as casting, milling, etc.

[0332] In this embodiment, by setting the connecting portion 231 and the clamping portion 232 of the locking member 23 as an integrally formed structure, the connection stability and structural strength between the connecting portion 231 and the clamping portion 232 can be improved, which is beneficial to reducing the risk of connection failure or falling off between the connecting portion 231 and the clamping portion 232, thereby improving the service life of the locking member 23 and improving the stability and reliability of the locking mechanism 20 locked on the lock seat 300.

[0333] According to some embodiments of the present application, referring to FIG. 16 , FIG. 17 and FIG. 18 , the clamping portion 232 and the connecting portion 231 are separately provided, and the clamping portion 232 is detachably connected to the connecting portion 231 .

The locking mechanism 20 with such a structure can, on the one hand, reduce the difficulty of assembling the locking member 23 and the lock sleeve 21, and on the other hand, The diameter of the assembly hole 211 through which the connecting portion 231 passes, located at one end of the lock sleeve 21 near the engaging portion 232 in the first direction X, is simply set to match the diameter of the connecting portion 231. This helps reduce the assembly gap between the connecting portion 231 of the locking member 23 and the lock sleeve 21, alleviates shaking during use of the locking mechanism 20, and reduces the risk of impurities entering the lock sleeve 21 through the gap between the connecting portion 231 of the locking member 23 and the lock sleeve 21, thereby effectively improving the service life and reliability of the locking mechanism 20. Furthermore, because the engaging portion 232 of the locking member 23 needs to engage with the lock base 300, if the engaging portion 232 becomes deformed or damaged, only the engaging portion 232 needs to be replaced, without having to replace the entire locking member 23. This helps reduce the subsequent maintenance costs of the locking mechanism 20.

[0336] In some embodiments, as shown in FIG. 18 , the clamping portion 232 is screwed to the connecting portion 231 .

[0337] Among them, the clamping part 232 is screwed to the outside of the connecting part 231, that is, the clamping part 232 is sleeved on the outside of the connecting part 231, and the clamping part 232 is provided with an internal thread. Correspondingly, the outer peripheral surface of the part of the first connecting section 2312 of the connecting part 231 inserted into the clamping part 232 is provided with an external thread to realize that the clamping part 232 is screwed to the outside of the connecting part 231.

[0338] In this embodiment, the clamping portion 232 is set as a structure that is screwed onto the connecting portion 231, so that the clamping portion 232 and the connecting portion 231 are threadedly connected structures, so as to realize a detachable connection between the clamping portion 232 and the connecting portion 231. The locking member 23 with such a structure is conducive to reducing the difficulty of assembly between the clamping portion 232 and the connecting portion 231, and can improve the structural stability and reliability of the clamping portion 232 connected to the connecting portion 231.
