Technical Field

[0001] This application relates to the field of cutting machinery technology, and in particular to a cutting mechanism, a cutter head, and a mounting structure. Background Technology

[0002] Cutting mechanisms are commonly found in various cutting machines, such as lawnmowers, in modern industry and daily life. The cutter head and mounting base are key components of the cutting mechanism; their function is to mount the cutter head on the mounting base and rotate it to achieve cutting.

[0003] While existing cutting mechanisms meet basic cutting needs to some extent, they still have some shortcomings in terms of blade assembly, disassembly, and fixation. Traditional blades typically require fasteners such as screws for fixation, making disassembly inconvenient. Summary of the Invention

[0004] The purpose of this application is to provide a cutting mechanism that, through the innovative design of a detachable connection between the cutter head and the mounting structure, and a movable structure, effectively solves the problem of inconvenient disassembly in traditional cutter head fixing methods, thereby improving the loading and unloading efficiency of cutting equipment. Another purpose of this application is to provide a cutter head and its mounting structure.

[0005] To achieve the above objectives, this application provides a cutting mechanism, including a cutter head and a mounting structure, wherein the cutter head is detachably connected to the mounting structure; the cutter head is provided with a first fastener;

[0006] The mounting structure includes:

[0007] The mounting base is provided with a second fastener, which is used to cooperate with the first fastener when the cutter head is rotated relative to the mounting base to the engagement position, so as to secure the cutter head on the mounting base.

[0008] A movable structure is provided on the mounting base, and the movable structure is used to cooperate with the cutter head when it moves to the first position, so as to restrict the rotation of the cutter head relative to the mounting base.

[0009] In some embodiments, the first fastener includes a first hook, and the second fastener includes a second hook;

[0010] The cutter head is also provided with a limiting part, which is used to cooperate with the movable structure when the movable structure moves to the first position, so as to limit the rotation of the cutter head relative to the mounting base.

[0011] In some embodiments, the limiting portion includes a limiting groove for the movable structure to engage to restrict the rotation of the cutter head relative to the mounting base; the first hook and the limiting groove are arranged along the rotation direction of the cutter head.

[0012] In some embodiments, a first elastic element is provided between the mounting base and the movable structure, the first elastic element being used to drive the movable structure toward the first position;

[0013] When the cutter head is installed, the cutter head presses against the movable structure, causing the movable structure to slide relative to the mounting base, so that the movable structure moves away from the first position. When the cutter head rotates relative to the mounting base to the engagement position, the movable structure moves to the first position under the elastic force of the first elastic element, so as to restrict the rotation of the cutter head relative to the mounting base.

[0014] In some embodiments, the cutter head has a through hole in the middle; the movable structure includes a pressing part, and when the cutter head is installed on the mounting base, at least a portion of the pressing part is located in the through hole, and the movable structure is moved away from the first position by pressing the pressing part.

[0015] In some embodiments, the cutter head is provided with an abutment wall and a limiting groove, the abutment wall extending along the rotation direction of the cutter head;

[0016] When the cutter head is installed, the abutting wall presses against the movable structure, causing the movable structure to move away from the first position. When the cutter head rotates relative to the mounting base to the engagement position, the abutting wall disengages from the movable structure, and the limiting groove rotates to a position corresponding to the movable structure. Under the elastic force of the first elastic member, the movable structure is engaged in the limiting groove to restrict the rotation of the cutter head.

[0017] In some embodiments, a second elastic element is provided between the mounting structure and the cutter head, the second elastic element being used to drive the cutter head to rotate relative to the mounting base away from the engagement position when the cutter head is not restricted to rotation by the movable structure.

[0018] In some embodiments, the mounting structure further includes a spring block; the second elastic element is connected between the spring block and the mounting base;

[0019] When the cutter head rotates relative to the mounting base in a first direction, the cutter head drives the spring block to move to compress the second elastic element; when the second elastic element is compressed, the spring block drives the cutter head to rotate relative to the mounting base in a second direction under the elastic force of the second elastic element; the first direction is opposite to the second direction.

[0020] In some embodiments, the limiting portion includes a positioning hole; the movable structure includes a push rod; when the first hook engages with the second hook, the push rod is pushed into the positioning hole to restrict the rotation of the cutter head relative to the mounting base;

[0021] The push rod includes a manual push rod and / or an electric push rod.

[0022] In some embodiments, the cutting mechanism further includes a power unit, the output end of which is connected to the mounting base. The power unit is used to drive the mounting base to rotate the cutter head. The movable structure is used to cooperate with the power unit when it moves to the second position to restrict the rotation of the mounting base relative to the power unit.

[0023] In some embodiments, the power unit is provided with an anti-rotation structure; when the movable structure moves to the second position, the movable structure cooperates with the anti-rotation structure to restrict the mounting base from rotating relative to the power unit;

[0024] The power unit includes a motor, the output shaft of which is connected to the mounting base, and the motor housing is provided with the anti-rotation structure; and / or,

[0025] The power unit includes a motor and a housing. The output shaft of the motor is connected to the mounting base, and the housing is connected to the outer casing of the motor. The housing covers the upper side of the cutter head and is equipped with the anti-rotation structure; and / or,

[0026] The power unit includes a lawnmower chassis, and the lawnmower chassis is equipped with the anti-rotation structure.

[0027] In some embodiments, the anti-rotation structure is an anti-rotation groove; when the movable structure moves to the second position, the movable structure engages with the anti-rotation groove to restrict the mounting base from rotating relative to the power device.

[0028] In some embodiments, the power unit is further provided with an error-proof platform, and the anti-rotation structure includes an anti-rotation groove provided on the error-proof platform; the cutter head is provided with a limiting groove;

[0029] When the movable structure engages with the anti-rotation groove, the movable structure disengages from the limiting groove; when the movable structure abuts against the error-proof platform, the movable structure engages at least partially with the limiting groove to restrict the rotation of the cutter head relative to the mounting base.

[0030] This application also provides a cutter head for mounting on a mounting structure, the mounting structure including a mounting base and a movable structure disposed on the mounting base; the cutter head is provided with a first fastener and a limiting part; when the cutter head is rotated and engaged with the mounting base by the first fastener, the movable structure cooperates with the limiting part to restrict the rotation of the cutter head relative to the mounting base.

[0031] This application also provides an installation structure for mounting a cutter head. The installation structure includes a mounting base, a movable structure disposed on the mounting base, and a second fastener disposed on the mounting base. The mounting base engages with a first fastener of the cutter head via the second fastener, thereby enabling the cutter head to rotate and engage with the mounting base. When the cutter head is rotated and engaged with the mounting base, the movable structure moves relative to the mounting base to a first position, engaging with the cutter head to restrict the rotation of the cutter head relative to the mounting base.

[0032] Compared to the aforementioned background technology, the cutting mechanism provided in this application mainly includes a cutter head and a mounting structure, wherein the cutter head and the mounting structure are detachably connected; the cutter head is provided with a first fastener; the mounting structure includes a mounting base and a movable structure, wherein the mounting base is provided with a second fastener, which is used to cooperate with the first fastener when the cutter head rotates relative to the mounting base to a mating position, so as to secure the cutter head on the mounting base; the movable structure is provided on the mounting base, and the movable structure is used to cooperate with the cutter head when it moves to a first position, so as to restrict the rotation of the cutter head relative to the mounting base.

[0033] In existing cutting machinery technology, the installation, removal, and fixation of the cutter head are crucial aspects. However, traditional methods typically rely on fasteners such as screws, which not only makes the disassembly process cumbersome but also difficult to complete quickly, affecting equipment maintenance efficiency. Furthermore, during high-speed rotating cutting, the cutter head may rotate relative to the cutter head due to friction or other external forces. This not only reduces cutting accuracy but may also lead to safety accidents.

[0034] To address these shortcomings, the cutting mechanism provided in this application employs an innovative design to achieve a quick and detachable connection between the cutter head and the mounting structure. Specifically, the cutter head is equipped with a first fastener, while the mounting base of the mounting structure has a matching second fastener. When the cutter head rotates relative to the mounting base to the engagement position, the first and second fasteners quickly engage, achieving rapid tightening of the cutter head. This design significantly simplifies the cutter head assembly and disassembly process, improving the efficiency of cutter head maintenance and replacement.

[0035] Equally important, the movable structure within the mounting structure, when moved to the first position, effectively engages with the cutter head, restricting its rotation relative to the mounting base. This movable structure design fundamentally solves the problem of relative rotation of the cutter head during operation, thus ensuring the stability and safety of the cutting process. Through this design, the cutter head can be stably maintained in the correct position during cutting operations, reducing the risk of uneven cutting or equipment damage caused by cutter head rotation.

[0036] Based on the above structural and process descriptions, it can be seen that the cutting mechanism has at least the following beneficial effects: Through the detachable connection between the cutter head and the mounting structure and the innovative design of the movable structure, the cutting mechanism effectively solves the problems of inconvenient disassembly and possible relative rotation during operation of the traditional cutter head fixing method, thereby improving the loading and unloading efficiency and operational safety of the cutting equipment.

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the cutting mechanism, cutter head, and mounting structure provided in the embodiments of this application. Figure 2 A cross-sectional view of the cutting mechanism, cutter head, and mounting structure provided in the embodiments of this application.

[0058] In the first specific implementation, such as Figure 1 and Figure 2 As shown, the cutting mechanism 100 provided in this embodiment mainly includes a cutter head 1 and a mounting structure 2.

[0059] The cutter head 1 is a key component of the cutting mechanism 100, responsible for directly contacting the material being cut and performing the cutting action.

[0060] Mounting structure 2 is used to fix the cutter head 1, ensuring its stability and accuracy during the cutting process.

[0061] When in use, the rotational power of the cutting mechanism 100 is transmitted to the mounting base 3. Since the cutter head 1 is fixed on the mounting structure 2, the mounting structure 2 drives the cutter head 1 to rotate, thereby realizing the cutting action.

[0062] In this embodiment, the cutting mechanism 100 has diverse applications, such as lawnmowers or lawnmower robots, but these are only a part of many application options. Due to the adaptability and flexibility of its design, the cutting mechanism 100 can be integrated into various mechanical devices that require cutting functions.

[0063] In some cases, the cutter head 1 is detachably connected to the mounting structure 2. This detachable connection design makes it easier and faster to install and remove the cutter head 1, improving the flexibility of use and maintenance efficiency of the cutting mechanism 100.

[0064] Please refer to Figure 3 and Figure 4 ,in, Figure 3 This is a schematic diagram of the cutter head provided in an embodiment of this application. Figure 4 This is a schematic diagram of the installation structure provided in an embodiment of this application.

[0065] In some cases, the mounting structure 2 includes a mounting base 3. The mounting base 3 is used to connect to the cutter head 1, thereby driving the cutter head 1 to rotate under the rotational power of the cutting mechanism 100. The cutter head 1 is provided with a first fastener 11, and the mounting base 3 is provided with a second fastener 31. The second fastener 31 is used to cooperate with the first fastener 11 when the cutter head 1 rotates relative to the mounting base 3 to the engagement position, so that the cutter head 1 is fastened on the mounting base 3.

[0066] Mounting structure 2 also includes movable structure 4. Movable structure 4 is located on mounting base 3 and is used to cooperate with cutter head 1 when it moves to the first position to restrict the rotation of cutter head 1 relative to mounting base 3.

[0067] In existing cutting machinery technology, the installation, removal and fixation of the cutter head 1 is a key link. However, traditional methods usually rely on fasteners such as screws, which not only makes the disassembly process of the cutter head 1 cumbersome, but also makes it difficult to complete quickly, affecting the maintenance efficiency of the equipment.

[0068] To address these shortcomings, the cutting mechanism 100 provided in this application achieves a quick and detachable connection between the cutter head 1 and the mounting structure 2 through an innovative design. Specifically, the cutter head 1 is provided with a first fastener 11, while the mounting base 3 of the mounting structure 2 is provided with a second fastener 31 that mates with it. When the cutter head 1 rotates relative to the mounting base 3 to the engagement position, the first fastener 11 and the second fastener 31 can quickly engage, achieving rapid fastening of the cutter head 1. This design significantly simplifies the loading and unloading process of the cutter head 1 and improves the efficiency of maintaining and replacing the cutter head 1.

[0069] Based on the aforementioned fixing method for the rotation of the cutter head 1 relative to the mounting base 3, and considering the potential for relative rotation of the cutter head 1 due to friction or other external forces during high-speed cutting, the cutting mechanism 100 provided in this application is further designed as follows: When the movable structure 4 in the mounting structure 2 moves to the first position, it can effectively cooperate with the cutter head 1, restricting the rotation of the cutter head 1 relative to the mounting base 3. This design of the movable structure 4 fundamentally solves the problem of potential relative rotation of the cutter head 1 during operation, thereby ensuring the stability and safety of the cutting process. Through this design, the cutter head 1 can stably maintain the correct position during cutting operations, reducing the risk of uneven cutting or equipment damage caused by the rotation of the cutter head 1.

[0070] Based on the above structural and process descriptions, it can be seen that the cutting mechanism 100 has at least the following beneficial effects: the cutting mechanism 100 effectively solves the problem of inconvenient disassembly in traditional fixing methods through the detachable connection between the cutter head 1 and the mounting structure 2 and the innovative design of the movable structure 4, thereby improving the loading and unloading efficiency of the cutting equipment; on this basis, it also solves the problem of relative rotation that may occur during the operation of the cutter head 1, thereby improving the operational safety of the cutting equipment.

[0071] Please continue to refer to this. Figure 3 And refer to Figure 5 , Figure 5 This is a schematic diagram of the mounting base provided in an embodiment of this application.

[0072] In some embodiments, the first fastener 11 includes a first hook 111, and the second fastener 31 includes a second hook 311.

[0073] In this embodiment, the second hook 311 engages with the first hook 111 to secure the cutter head 1 to the mounting base 3. The arrangement of the first hook 111 and the second hook 311 allows the cutter head 1 to be tightly engaged with the mounting base 3 through a snap-fit ​​mechanism, providing a simple and quick installation method.

[0074] In some embodiments, the cutter head 1 is further provided with a limiting part 13, which is used to cooperate with the movable structure 4 when the movable structure 4 moves to the first position, so as to limit the rotation of the cutter head 1 relative to the mounting base 3.

[0075] In this embodiment, the cutter head 1 also includes a limiting part 13 to further improve the stability of the cutter head 1 within the mounting base 3. The main function of the movable structure 4 is to engage with the limiting part 13 of the cutter head 1 after it is mounted on the mounting base 3, thereby preventing the cutter head 1 from rotating relative to the mounting base 3. This locking mechanism ensures the stability and accuracy of the cutter head 1 during cutting operations, preventing errors or damage caused by rotation.

[0076] It should be noted that, based on the cooperation of the first hook 111 and the second hook 311 to provide the tool disc 1 to be locked on the mounting base 3, the combination relationship between the movable structure 4 and the limiting part 13 can be regarded as the second locking.

[0077] When the movable structure 4 engages with the limiting part 13, it forms a stable locking system in conjunction with the second hook 311 and the first hook 111. This structure not only improves the fixing security of the cutter head 1 but also enhances the reliability of the entire cutting mechanism 100. Through this design, the cutter head 1 can maintain a precise position during the cutting process, thereby ensuring cutting quality and facilitating maintenance and replacement of the cutter head 1 by the operator.

[0078] It should be noted that this embodiment does not limit the specific structure of the movable structure 4 and the limiting part 13, nor the movement form of the movable structure 4. For example, regarding the specific structure, the movable structure 4 can be a block structure, and the limiting part 13 can adopt a limiting groove to facilitate the insertion of the block structure; the movable structure 4 can be a rod structure, and the limiting part 13 can adopt a limiting hole to facilitate the insertion of the rod structure. For example, regarding the movement form, the movable structure 4 can move axially or radially, and the movement mode can be translation or rotation, as long as it can achieve engagement with the limiting part 13 in a certain state of movement. Therefore, the movable structure 4 and the limiting part 13 in different embodiments should all fall within the scope of this application.

[0079] Please continue to refer to this. Figure 3 In some embodiments, the limiting part 13 includes a limiting groove 131, which is used for the movable structure 4 to be engaged to limit the rotation of the cutter head 1 relative to the mounting base 3; the first hook 111 and the limiting groove 131 are arranged along the rotation direction of the cutter head 1.

[0080] In this embodiment, when the movable structure 4 engages with the limiting groove 131, it can prevent the cutter head 1 from moving along the rotation direction, ensuring that the cutter head 1 maintains a fixed position during the cutting process, thereby improving the accuracy and reliability of the cutting. The first hook 111 and the limiting groove 131 are designed to be set at different circumferential positions along the cutter head 1. This design means that the first hook 111 and the limiting groove 131 occupy different angular positions on the circumference of the cutter head 1, and they perform their respective functions when the cutter head 1 rotates to a specific position.

[0081] Specifically, when the cutter head 1 rotates to a certain angle, at one angular position of the cutter head 1, the first latch 111 can engage with the second latch 311 to quickly lock the cutter head 1; simultaneously, at another angular position of the cutter head 1, the movable structure 4 engages in the limiting groove 131 to restrict further rotation of the cutter head 1. This design of different circumferential positions allows the cutter head 1 to perform different mechanical actions at different circumferential positions during installation, improving the fitting accuracy between the cutter head 1 and the mounting structure 2 and the flexibility of operation.

[0082] It should be noted that this embodiment does not limit the driving principle of the movable structure 4. For example, the movable structure 4 can move downward to the first position by its own gravity, or it can move downward to the first position by the elastic force of a passive component such as a spring, or it can move downward to the first position by the pushing force of an active component such as an electric push rod. Therefore, the movable structure 4 in different embodiments should all fall within the scope of this application.

[0083] In some embodiments, the limiting part 13 includes a positioning hole; the movable structure 4 includes a push rod; when the first hook 111 engages with the second hook 311, the push rod is pushed into the positioning hole to limit the rotation of the cutter head 1 relative to the mounting base 3.

[0084] It should be noted that whether it is the limiting groove 131, the positioning hole, or a combination of both, the effect of limiting the rotation of the cutter head 1 relative to the mounting base 3 can be achieved. The push rod can be a manual push rod or an electric push rod, both of which should be within the scope of this embodiment.

[0085] In some embodiments, a first elastic element is provided between the mounting base 3 and the movable structure 4, the first elastic element being used to drive the movable structure 4 toward a first position.

[0086] In this embodiment, under the elastic force of the first elastic element, the movable structure 4 moves toward the cutter head 1 to a first position and engages with the cutter head 1. This engagement effectively restricts the rotation of the cutter head 1 relative to the mounting base 3, ensuring the stability of the cutter head 1 and the safety of operation during the cutting process.

[0087] Optionally, the first elastic element is a spring, with the first end of the spring fixed on the mounting base 3 and the second end of the spring connected to or in contact with the movable structure 4, so that the movable structure 4 has a tendency to move toward the first position.

[0088] Please refer to Figure 6 and Figure 7 ,in, Figure 6 This is a schematic diagram of the active structure provided in the embodiments of this application. Figure 7 This is a schematic diagram of the mounting base and movable structure provided in the embodiments of this application.

[0089] In some embodiments, the movable structure 4 is slidably assembled to the mounting base 3. The movable structure 4 includes a first mating part 42 and a second mating part 43 connected together, and the second mating part 43 is slidably mated to the mounting base 3.

[0090] In this embodiment, the sliding assembly of the movable structure 4 simplifies the assembly and maintenance process of the entire cutting mechanism 100. The operator can easily adjust or replace the movable structure 4 without the need for complex disassembly of the entire cutting mechanism 100. This design reflects user-friendliness while also improving the maintenance efficiency and service life of the cutting mechanism 100.

[0091] When the cutter head 1 is installed, it presses against the first mating part 42. This action causes the second mating part 43 to slide along the mounting base 3, thereby moving the movable structure 4 away from the first position. This movement ensures that the cutter head 1 can extend into the mounting structure 2 and smoothly rotate relative to the mounting base 3 to the correct engagement position. Once the cutter head 1 reaches this position, it releases pressure on the first mating part 42.

[0092] Subsequently, due to the elastic force of the first elastic element, the movable structure 4 moves towards the first position. At this time, the first mating part 42 interacts with the cutter head 1, thereby restricting the rotation of the cutter head 1. This design not only simplifies the installation process of the cutter head 1, but also ensures the stability of the cutter head 1 during the cutting process through elastic restoring force, preventing displacement or instability caused by rotation, thereby improving the accuracy and safety of cutting.

[0093] In some embodiments, the cutter head 1 has a through hole 14 in the middle; the movable structure 4 also includes a pressing part 41 connected to the first mating part 42 and / or the second mating part 43. When the cutter head 1 is installed on the mounting base 3, at least a portion of the pressing part 31 is located in the through hole 14. By pressing the pressing part 41, the movable structure 4 moves in a direction away from the first position.

[0094] It should be noted that whether the pressing part 41 is connected to the first mating part 42, the pressing part 41 is connected to the second mating part 43, or the pressing part 41 is connected to both the first mating part 42 and the second mating part 43, all should fall within the scope of this embodiment.

[0095] For example, the pressing part 41, the first mating part 42 and the second mating part 43 are connected in sequence. The radial inner side of the first mating part 42 is connected to the pressing part 41, and the two sides of the second mating part 43 are slidably mated with the mounting base 3. The axial free end of the first mating part 42 serves to be inserted into the limiting groove 131.

[0096] In this embodiment, the design of the cutter head 1 specifically considers the needs of user operation and maintenance. Specifically, the middle section of the cutter head 1 is hollowed out. This design not only reduces the weight of the cutter head 1 but also provides operating space for the movable structure 4. The pressing part 41 of the movable structure 4 can protrude from the through hole 14 in the middle of the cutter head 1, allowing the user to directly press the pressing part 41. Furthermore, the through hole 14 in the middle of the cutter head 1 exposes the pressing part 41 of the movable structure 4. The boss structure of the pressing part 41 can help the user position the cutter head 1, ensuring it is aligned with the installation position.

[0097] With this design, users can easily move the movable structure 4 away from the first position by pressing the pressing part 41 of the movable structure 4, thereby releasing the locking of the mounting structure 2 on the cutter head 1.

[0098] It should be noted that this embodiment does not limit the setting method of the active structure 4. The active structure 4 obtained by using different setting methods should also fall within the scope of this embodiment.

[0099] For example, the pressing part 41, the first mating part 42, and the second mating part 43 are integrally molded. This design can reduce assembly costs, improve production efficiency, and, due to being integrally molded, the overall structure has higher stability and durability.

[0100] For example, the pressing part 41, the first mating part 42, and the second mating part 43 are assembled separately. In this design, the pressing part 41, the first mating part 42, and the second mating part 43 are manufactured separately and then combined together during the assembly process, which has greater flexibility, facilitates individual optimization design of each component, and also facilitates maintenance and replacement, because if a part is damaged, only the damaged part needs to be replaced.

[0101] In some embodiments, the cutter head 1 is provided with an abutment wall 15 and a limiting groove 131. The abutment wall 15 and the limiting groove 131 are arranged along the rotation direction of the cutter head 1. The abutment wall 15 extends along the rotation direction of the cutter head 1 and is used to axially abut against the first mating part 42.

[0102] When installing the cutter head 1, the abutting wall 15 presses against the first mating part 42, causing the movable structure 4 to move away from the first position, so that the cutter head 1 can be inserted into the mounting base 3. Then the cutter head 1 is rotated until the cutter head 1 rotates relative to the mounting base 3 to the engagement position. The first hook 111 engages with the second hook 311, and the limiting groove 131 rotates to the position corresponding to the first mating part 42. The movable structure 4 moves to the first position under the elastic force of the first elastic element, and the first mating part 42 is engaged in the limiting groove 131 to restrict the rotation of the cutter head 1.

[0103] In some embodiments, a second elastic member is provided between the mounting structure 2 and the cutter head 1. The second elastic member is used to drive the cutter head 1 to move away from the engagement position when the rotation of the cutter head 1 is not restricted by the movable structure 4.

[0104] In this embodiment, by providing a second elastic element, a disengagement force is provided for the cutter head 1, which not only simplifies the disassembly process of the cutter head 1, but also improves the operational safety of the entire cutting mechanism 100.

[0105] When the cutter head 1 is not restricted by the movable structure 4, i.e., in the unlocked state, the second elastic element will function, causing the cutter head 1 to move away from its engagement position with the mounting base 3. The second elastic element ensures that the cutter head 1 will not accidentally remain connected to the mounting base 3 or jam during disassembly, thus making maintenance and replacement work smoother and safer.

[0106] Optionally, the second elastic element is a torsion spring or a spring, with the first end of the spring body fixed on the mounting base 3 and the second end of the spring body in contact with the cutter head 1, so that the cutter head 1 has a tendency to move away from the engagement position.

[0107] In some embodiments, the mounting structure 2 further includes a spring block; a second elastic element is connected between the spring block and the mounting base 3.

[0108] In this embodiment, the mounting structure 2 is equipped with a spring block and a second elastic element. When the cutter head 1 rotates relative to the mounting base 3 in the first direction, causing the cutter head 1 to move towards the engagement position, the cutter head 1 will drive the spring block to compress the second elastic element. This process usually occurs when installing the cutter head 1. Due to the compression of the second elastic element, it generates an elastic force. This elastic force causes the spring block to push the cutter head 1 to rotate in the opposite direction, i.e., the second direction, causing the cutter head 1 to move away from the engagement position. This process usually occurs when disassembling the cutter head 1. Through the combined action of the second elastic element and the spring block, the bidirectional rotational movement of the cutter head 1 is achieved.

[0109] In some embodiments, the mounting base 3 is further provided with an anti-reverse part 32. The second fastener 31 and the anti-reverse part 32 are arranged along the rotation direction of the mounting base 3. The anti-reverse part 32 is used to limit the rotation direction of the cutter head 1 relative to the mounting base 3.

[0110] In this embodiment, the design of the mounting base 3 takes into account the intuitiveness of operation and the possibility of misoperation. To this end, the mounting base 3 is provided with a special anti-reverse part 32. The main function of the anti-reverse part 32 is to limit the rotation direction of the cutter head 1 relative to the mounting base 3, ensuring that the cutter head 1 can only rotate in a specific direction.

[0111] This unidirectional rotation design is crucial because it allows the cutter head 1 to engage with the first latch 111 and the second latch 311 with the shortest possible stroke. This means that when installing or removing the cutter head 1, the user avoids large-angle rotations and only needs to perform minimal rotations, thus improving operational efficiency and convenience. At the same time, this design also prevents the user from rotating the cutter head 1 in the opposite direction, avoiding engagement failures or operational inconveniences caused by excessive rotation angles.

[0112] Furthermore, after the first hook 111 and the second hook 311 are engaged, the anti-reverse part 32 can also prevent the cutter head 1 from rotating relative to the mounting base 3, thus preventing the first hook 111 and the second hook 311 from becoming misaligned. The anti-reverse part 32 restricts the rotation of the cutter head 1 relative to the mounting base 3, ensuring the positioning accuracy of the cutter head 1 and preventing the risk of reduced cutting efficiency or equipment damage due to rotational misalignment.

[0113] In this embodiment, on the side of the anti-reverse part 32 adjacent to the second fastener 31, the second elastic member drives the cutter head 1 to move away from the anti-reverse part 32.

[0114] In some cases, there are multiple second hooks 311 and anti-reverse parts 32. One second hook 311 and one anti-reverse part 32 form a hook group. Multiple hook groups are arranged along the rotation direction of the mounting base 3. A notch 33 is formed between adjacent hook groups. The notch 33 is used for the first hook 111 to enter and exit the mounting base 3.

[0115] In this embodiment, the mounting base 3 is designed with repeating unit structures, namely multiple second hooks 311 and anti-reverse parts 32. These structural units exist in the form of hook groups, each hook group consisting of one second hook 311 and one anti-reverse part 32 adjacent to each other. Such hook groups are arranged continuously along the rotation direction of the mounting base 3, forming a periodic structural layout.

[0116] Notches 33 are intentionally designed between these hook assemblies. These notches 33 are located between adjacent hook assemblies, and their existence is to provide a space so that the first hook 111 can smoothly enter or exit the mounting base 3. This design allows the cutter head 1 to achieve a quick and easy installation and removal process through the interaction of the first hook 111 and the second hook 311.

[0117] The periodic arrangement of the hooks and notches 33 not only improves the efficiency of installing and removing the cutter head 1, but also enhances the stability of the cutter head 1 on the mounting base 3 by ensuring the correct engagement between the first hook 111 and the second hook 311. This configuration helps reduce errors during installation, while improving the reliability and ease of maintenance of the entire cutting mechanism 100.

[0118] like Figure 5 As shown, a mounting base 3 with a specific configuration is illustrated. Figure 5 The number of the second hook 311 and the anti-reverse part 32 are both two. One second hook 311 and one anti-reverse part 32 form a group. In the rotation direction, the two groups are spaced apart to form a notch 33. The notch 33 is used to allow the first hook 111 on the cutter head 1 to extend into the mounting base 3 to realize the installation of the cutter head 1.

[0119] In some cases, the anti-reverse part 32 extends in the rotation direction of the mounting base 3, and the first end of the anti-reverse part 32 in the rotation direction is adjacent to the second hook 311 to restrict the rotation of the first hook 111. A notch 33 is formed between the second end of the anti-reverse part 32 in the rotation direction and the second hook 311 in the adjacent hook group.

[0120] In this embodiment, the anti-reflection part 32 is designed to extend in the rotational direction of the mounting base 3, allowing it to form a continuous arc-shaped structure. This structure not only presents a smooth and unified visual appearance but also offers significant functional advantages.

[0121] Specifically, the first end of the anti-reverse part 32 in the rotational direction is designed to be adjacent to the second hook 311. The main function of this end is to restrict the rotation of the first hook 111, ensuring the correct positioning and fixation of the cutter head 1 on the mounting base 3. This adjacent arrangement of the anti-reverse part 32 effectively prevents misalignment between the first hook 111 and the second hook 311, thereby ensuring the stability of the cutter head 1 and the accuracy of cutting.

[0122] Meanwhile, a notch 33 is formed between the second end of the anti-reverse part 32 in the rotational direction and the second hook 311 in the adjacent hook group. The presence of the notch 33 provides a channel for the first hook 111 to enter and exit, making the installation and disassembly process of the cutter head 1 simpler and faster.

[0123] Therefore, the anti-reflection section 32 adopts a continuous arc-shaped structure design. This design not only enhances the overall integrity and strength of the structure but also effectively reduces manufacturing costs by decreasing the number of parts and joints. The continuity of the arc-shaped structure helps improve the stability of the anti-reflection section 32 while simplifying the manufacturing process and reducing assembly complexity. Furthermore, this design delivers economic benefits while ensuring technical efficiency and operational reliability, as it achieves improved product performance and reduced costs by minimizing additional costs in the production process.

[0124] Optionally, there are two first hooks 111, which are symmetrically arranged along the rotation direction of the cutter head 1; there are two second hooks 311, which are symmetrically arranged on the inner side of the mounting base 2 along the rotation direction of the mounting base 3.

[0125] In some embodiments, the cutter head 1 is provided with a first anti-mistake part 16, and the mounting structure 2 is provided with a second anti-mistake part 44. The first anti-mistake part 16 and the second anti-mistake part 44 cooperate to prevent the cutter head 1 from being installed incorrectly.

[0126] In this embodiment, the foolproof design of the cutter head 1 and the mounting structure 2 ensures that the cutter head 1 can only be installed on the mounting structure 2 in the correct position, effectively preventing the problem of incorrect installation of the cutter head 1, improving the accuracy of assembly and the safety of equipment use.

[0127] Optionally, the first anti-mistake part 16 is in the form of a protrusion, and the second anti-mistake part 44 is in the form of a slot; the protrusion is provided on the cutter head 1, and the slot is provided on the movable structure 4. During installation, due to the anti-mistake design of the slot, the cutter head 1 needs to be rotated relative to the mounting structure 2 to the accurate installation angle so that the protrusion and the slot are aligned, and then the cutter head 1 can be inserted into the mounting structure 2 for installation.

[0128] In some cases, the cutter head 1 is provided with an annular flange 12, which faces the mounting base 3. The annular flange 12 is provided with a first hook 111, an abutment wall 15, a limiting groove 131, and a first anti-fooling part 16. The abutment wall 15 and the limiting groove 131 are arranged along the rotation direction of the cutter head 1. The first hook 111 is located on the outer side of the annular flange 12, and the first anti-fooling part 16 is located on the inner side of the annular flange 12. In the radial direction of the cutter head 1, the first hook 111 protrudes from the radial outer edge of the abutment wall 15. In the axial direction of the cutter head 1, the limiting groove 131 is recessed into the axial surface of the abutment wall 15. When installing the cutter head 1, the abutment wall 15 pushes the movable structure 4 to move away from the first position. Then, the cutter head 1 is rotated, the abutment wall 15 separates from the movable structure 4, and the first elastic element drives the movable structure 4 to engage with the limiting groove 131. The first hook 111 cooperates with the second hook 311.

[0129] Optionally, the second anti-fooling part 44 is located on the outside of the pressing part 41. When installing the cutter head 1, the pressing part 41 is positioned with the through hole 14, and the second anti-fooling part 44 needs to cooperate with the first anti-fooling part 16 to extend the cutter head 1 into the mounting structure 2.

[0130] In this embodiment, the design of the cutter head 1 includes an important structural feature: the annular flange 12 is oriented toward the mounting base 3. Its design purpose is to provide a stable interface so that the cutter head 1 can smoothly engage with the mounting base 3.

[0131] The first hook 111 is located on the outer side of the annular flange 12. It is designed to protrude radially from the cutter head 1, specifically protruding from the radial outer edge of the abutment wall 15. This design allows the first hook 111 to effectively engage with the second hook 311 on the mounting base 3 when the cutter head 1 is installed onto the mounting base 3, thereby achieving the fastening of the cutter head 1.

[0132] The abutment wall 15 is the part that interacts with the movable structure 4. It is formed axially on the cutter head 1 and provides a driving force to the movable structure 4, enabling it to move to the desired position. When the cutter head 1 is installed, the abutment wall 15 pushes the movable structure 4, causing it to engage in the anti-rotation groove 511, which facilitates the installation of the cutter head 1.

[0133] The limiting groove 131 is recessed in the axial direction of the cutter head 1 on the axial surface of the abutment wall 15. Its function is to provide a locking point when the movable structure 4 moves to the first position, so that the movable structure 4 can be stably locked in, thereby limiting the rotation of the cutter head 1 relative to the mounting base 3 and ensuring the stability of the cutter head 1 during operation.

[0134] In some cases, the mounting base 3 is provided with a positioning platform 34 inside, which is used to abut against the abutment wall 15 to prevent the cutter head 1 from tilting.

[0135] In this embodiment, the mounting base 3 is specially designed with a positioning platform 34 inside. The main function of this positioning platform 34 is to abut against the abutment wall 15. Through this abutment, the positioning platform 34 can effectively position the cutter head 1, ensuring that it is correctly aligned within the mounting base 3 and preventing the cutter head 1 from becoming skewed during installation or use.

[0136] Please continue to refer to this. Figure 1 In some embodiments, the cutting mechanism 100 further includes a power device 5, the output end of which is connected to the mounting base 3. The power device 5 is used to drive the mounting base 3 to rotate the cutter head 1. The movable structure 4 is used to cooperate with the power device 5 when it moves to the second position to restrict the rotation of the mounting base 3 relative to the power device 5.

[0137] In this embodiment, the power unit 5 outputs rotational power to drive the mounting base 3 to rotate, thereby causing the cutter head 1 to rotate and cut. When an external force is applied to the movable structure 4, the movable structure 4 overcomes the force of the first elastic element and moves to a second position away from the first position, cooperating with the power unit 5. This design allows the mounting base 3 to be restricted from rotating relative to the power unit 5 when the cutter head 1 needs to be loaded or unloaded, making the loading and unloading process of the cutter head 1 more convenient and faster, while also avoiding operational interference caused by the rotation of the mounting base 3. Through this design, the movable structure 4 not only improves the fixed stability of the cutter head 1, but also optimizes the efficiency and safety of the loading and unloading process.

[0138] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the active structure and anti-rotation structure provided in the embodiments of this application.

[0139] In some embodiments, the power unit 5 is provided with an anti-rotation structure 51; when the movable structure 4 moves to the second position, the movable structure 4 cooperates with the anti-rotation structure 51 to restrict the mounting base 3 from rotating relative to the power unit 5. Specifically, the second mating part 43 cooperates with the anti-rotation structure 51.

[0140] In this embodiment, the second mating part 43 not only serves a guiding function but also cooperates with the anti-rotation structure 51 to restrict the rotation of the mounting base 3 relative to the power unit 5. When the user needs to install or remove the cutter head 1, the movable structure 4 can be operated to engage with the anti-rotation structure 51 to fix the mounting base 3 and prevent it from rotating. This design ensures that the cutter head 1 can be accurately and stably installed on the mounting base 3 without worrying about alignment problems caused by the rotation of the mounting base 3. Once the cutter head 1 is installed in place, the engagement between the movable structure 4 and the anti-rotation structure 51 is released, and the cutter head 1 can rotate freely under the drive of the power unit 5 to perform normal cutting work. Therefore, the introduction of this structure only plays a role in the installation and removal stages of the cutter head 1, and does not affect its rotation performance when the cutter head 1 is working normally, ensuring cutting efficiency and safety.

[0141] In one specific embodiment, the power unit 5 includes a motor 6 and a cover 7. The motor 6 is connected to the mounting base 3, and the cover 7 is connected to the motor 6. In the axial direction of the cutting mechanism 100, the cutter head 1 is located below the mounting base 3, and the cover 7 is located above the cutter head 1.

[0142] In some cases, the cutting mechanism 100 is located on the lawnmower, and the lawnmower chassis can also be regarded as a component of the lawnmower, through which the installation and support of the other components in the cutting mechanism 100 are achieved.

[0143] The motor 6 is connected to the mounting base 3, and its main function is to provide power to drive the mounting base 3, which in turn drives the cutter head 1 to rotate. This design enables the cutter head 1 to perform efficient cutting operations under the drive of the motor 6, improving the working performance and efficiency of the entire cutting mechanism 100.

[0144] The cover 7 is fixed to the motor 6. The main function of the cover 7 is to divide the space vertically, ensuring that the cutter head 1 is located on the lower side, thus forming a safety barrier for the user during operation. This design effectively protects the user from potential injury caused by the rotating cutter head 1, while also preventing debris or other materials from splashing into the operator or the surrounding environment.

[0145] In this embodiment, the cutter head 1 is located on the lower side of the mounting base 3, facilitating cutting operations. Simultaneously, the movement path of the movable structure 4 is carefully designed to enable precise axial movement, allowing for compatibility with different structures.

[0146] It should be noted that this embodiment does not limit the specific object that the movable structure 4 cooperates with the power device 5 in the second position, nor the setting position of the anti-rotation structure 51. Therefore, any embodiment schemes that arise due to different specific objects of cooperation and different setting positions of the anti-rotation structure 51 should also fall within the scope of this application.

[0147] Optionally, the movable structure 4 engages with the motor 6 when it moves to the second position. When the movable structure 4 engages with the motor 6, it can be considered that the mounting base 3 and the movable structure 4 are fixed to the motor 6 as a whole, thereby restricting the rotation of the mounting base 3. For example, the anti-rotation structure 51 is provided on the motor 6.

[0148] Furthermore, the motor 6 includes an output shaft, a motor mounting base, and a housing. The output shaft is connected to the mounting base 3. The mating objects of the movable structure 4 include, but are not limited to, the motor mounting base and the housing. The setting position of the anti-rotation structure 51 includes, but is not limited to, the mounting base and the housing.

[0149] Preferably, the output shaft of the motor 6 is connected to the mounting base 3, and the movable structure 4 engages with the housing of the motor 6. Because the output shaft can rotate relative to the housing, the mounting base 3 is driven to rotate by the output shaft. At the same time, when the movable structure 4 moves to the second position, it engages with the housing, restricting the rotation of the mounting base 3 relative to the housing.

[0150] Optionally, the movable structure 4 engages with the cover 7 when it moves to the second position. When the movable structure 4 engages with the cover 7, it can be considered that the mounting base 3 and the movable structure 4 are fixed together with the cover 7, thereby restricting the rotation of the mounting base 3. For example, an anti-rotation structure 51 is provided on the cover 7.

[0151] Preferably, the cover 7 is connected to the housing of the motor 6, and the movable structure 4 is engaged with the cover 7. Because the output shaft can rotate relative to the cover 7, the mounting base 3 is driven to rotate by the output shaft. At the same time, when the movable structure 4 moves to the second position, it engages with the cover 7, restricting the rotation of the mounting base 3 relative to the cover 7.

[0152] Optionally, when the movable structure 4 moves to the second position, it engages with the lawnmower chassis. When the movable structure 4 engages with the lawnmower chassis, it can be considered that the mounting base 3 and the movable structure 4 are a whole fixed to the lawnmower chassis, thereby restricting the rotation of the mounting base 3. For example, the anti-rotation structure 51 is provided on the lawnmower chassis.

[0153] Specifically, because the output shaft can rotate relative to the lawnmower chassis, the mounting base 3 is driven to rotate by the output shaft. At the same time, when the movable structure 4 moves to the second position, it cooperates with the lawnmower chassis, restricting the rotation of the mounting base 3 relative to the lawnmower chassis.

[0154] This embodiment does not limit the form of cooperation between the movable structure 4 and the power device 5 in the second position. Referring to the description of the form of cooperation between the movable structure 4 and the cutter head 1 in the first position, the form of cooperation between the movable structure 4 and the power device 5 in different embodiments should also fall within the scope of this application.

[0155] In some cases, the anti-rotation structure 51 can be selected as the anti-rotation groove 511, and the movable structure 4 can be engaged with the anti-rotation groove 511 to achieve a fit.

[0156] Both the limiting groove 131 and the anti-rotation groove 511 are designed to restrict the circumferential angular position of the movable structure 4 at a specific axial position, thereby limiting the rotation of the cutter head 1 and the mounting base 3. When the movable structure 4 slides along its movement path to the first position, it will engage in the limiting groove 131; this action restricts the rotation of the cutter head 1, ensuring its stability during cutting operations. When the movable structure 4 slides along its movement path to the second position, it will engage in the anti-rotation groove 511; this action restricts the rotation of the mounting base 3 relative to the power unit 5, ensuring the stability of the cutter head 1 during installation or disassembly.

[0157] Specifically, when the movable structure 4 moves to the first position, the first mating part 42 engages with the limiting groove 131, restricting the rotation of the cutter head 1, while the second mating part 43 disengages from the anti-rotation groove 511, so that the mounting base 3 can rotate; when the movable structure 4 moves to the second position, the second mating part 43 engages with the anti-rotation groove 511, restricting the rotation of the mounting base 3 relative to the power device 5, while the first mating part 42 disengages from the limiting groove 131, so that the cutter head 1 can rotate relative to the mounting base 3.

[0158] Optionally, there are multiple limiting grooves 131 and anti-rotation grooves 511, which are spaced apart along the rotation direction of the cutting mechanism 100. This design provides greater flexibility and adaptability because it allows the movable structure 4 to be locked in multiple positions, thereby limiting the rotation of the cutter head 1 and the mounting base 3 at different circumferential angles.

[0159] When the movable structure 4 needs to restrict the rotation of the cutter head 1 and the mounting base 3, it can engage with any of the limiting grooves 131 or anti-rotation grooves 511. This multi-position locking mechanism allows the installation and removal of the cutter head 1 to be carried out stably at multiple angles, without being limited by a single locking point. This not only improves the convenience of the installation process, but also increases the operational safety and reliability of the entire cutting mechanism 100.

[0160] In some cases, the mounting base 3 is provided with a limiting platform 35 and a stop 36, and an active space 37 is formed between the limiting platform 35 and the stop 36 for the axial movement of the movable structure 4.

[0161] In this embodiment, when the movable structure 4 moves to the first position, it abuts against the stop 36. This position is typically where the movable structure 4 fixes the cutter head 1 in its working state. The stop 36 restricts further movement of the movable structure 4, ensuring that it can stably fix the cutter head 1 in the first position. A first elastic element is provided on the limiting platform 35 and connected to the movable structure 4. When the movable structure 4 moves to the second position, the first elastic element on the limiting platform 35 is compressed, thus restricting further movement of the movable structure 4. This position is typically where the movable structure 4 is loading and unloading the cutter head 1.

[0162] Optionally, when the first elastic element is set on the mounting base 3 at a position other than the limiting platform 35, the second position of the movable structure 4 can be defined as moving to a position that abuts against the limiting platform 35. The limiting platform 35 here serves to restrict the movement of the other end of the movable structure 4, ensuring that the cutter head 1 can be safely loaded and unloaded in the second position.

[0163] With this design, the movable structure 4 can move accurately between two preset positions, achieving stable fixation and convenient installation and removal of the cutter head 1, while ensuring the efficient operation and safety of the installation structure.

[0164] In some embodiments, the mounting base 3 has an opening on the side facing the power unit 5, and the opening communicates with the active space 37; the first mating part 42 is restricted to move between the limiting platform 35 and the stop part 36, and the second mating part 43 extends out from the opening toward the power unit 5.

[0165] In this embodiment, the mounting base 3 is specially designed with an opening located on the side facing the power unit 5 and communicating with the movable space 37. This design allows the second mating part 43 of the movable structure 4 to extend from this opening, directly facing the power unit 5, thereby engaging with the power unit 5 when the movable structure 4 moves to the second position.

[0166] The first mating part 42 is designed to move between the limiting platform 35 and the stop part 36. The moving distance of the first mating part 42 is the moving distance of the movable structure 4. On the moving path of the movable structure 4, the first mating part 42 is mated and separated from the cutter head 1, and the second mating part 43 is mated and separated from the power device 5.

[0167] With this configuration, the movable structure 4 can flexibly switch between a first position and a second position. In the first position, it cooperates with the cutter head 1 to perform cutting operations, while in the second position, it cooperates with the power unit 5 to facilitate the loading, unloading, and maintenance of the cutter head 1. This design not only improves the operational efficiency of the installation structure but also increases its convenience and safety.

[0168] In some embodiments, the power unit 5 is further provided with a fault-prevention platform 52, and the anti-rotation structure 51 includes an anti-rotation groove 511 provided in the fault-prevention platform 52;

[0169] When the second mating part 43 engages in the anti-rotation groove 511, the first mating part 42 disengages from the limiting groove 131; when the second mating part 43 comes into contact with the error-proof platform 52, the first mating part 42 engages at least partially in the limiting groove 131 to limit the rotation of the cutter head 1 relative to the mounting base 3.

[0170] In this embodiment, the power unit 5 incorporates a fault-prevention platform 52. When the second mating part 43 correctly engages with the anti-rotation groove 511, the first mating part 42 disengages from the limiting groove 131, allowing the cutter head 1 to rotate. Conversely, when the second mating part 43 contacts the fault-prevention platform 52, the first mating part 42 at least partially engages with the limiting groove 131, locking the cutter head 1 and preventing it from rotating.

[0171] Understandably, if the cutter head 1 and the mounting base 3 as a whole do not rotate relative to the power device 5 to a position matching the anti-rotation groove 511, the second mating part 43 will not be able to engage with the anti-rotation groove 511, but will instead abut against the error-proof platform 52. This is equivalent to the error-proof platform 52 restricting the movement of the movable structure 4, shortening the movement distance of the first mating part 42, and preventing the first mating part 42 from completely disengaging from the limiting groove 131. When the cutting mechanism 100 is operating, this design prevents the cutter head 1 from falling off due to accidental contact with the movable structure 4. For example, during the operation of the lawnmower, if the movable structure 4 comes into contact with stones on the ground and is compressed, the error-proof platform 52 will restrict the movement of the movable structure 4, preventing the cutter head 1 from separating from the mounting base 3 due to misoperation, thereby improving safety during use.

[0172] In one specific embodiment, the installation and disassembly process of the cutter head 1 and the mounting structure 2 in the cutting mechanism 100 is described as follows.

[0173] During installation, align the first hook 111 on the cutter head 1 with the notch 33 on the mounting base 3, align the through hole 14 of the cutter head 1 with the pressing part 41 of the movable structure 4, and align the first anti-fooling part 16 of the cutter head 1 with the second anti-fooling part 44 of the movable structure 4. Since the cutter head 1 is located below the mounting base 3, push the cutter head 1 upwards, and the abutting wall 15 abuts against the lower end face of the first mating part 42 and pushes the movable structure 4 upwards until the abutting wall 15 abuts against the positioning platform 34. At this time, the movable structure 4 moves upwards to the second position, and the upper end face of the second mating part 43 enters the anti-rotation groove 511. The second mating part 43 is locked upwards into the anti-rotation groove 511, at which point the rotation of the mounting base 3 is restricted; at the same time, the first hook 111 moves upwards... The upper mounting base 3 is inserted, and the cutter head 1 is rotated forward relative to the mounting base 3. After the first hook 111 rotates circumferentially, it engages with the second hook 311, making the cutter head 1 and the mounting base 3 secure. At this time, the anti-reverse part 32 restricts the rotation of the cutter head 1 relative to the mounting base 3. The restriction direction includes one rotation direction in the forward direction to prevent the first hook 111 and the second hook 311 from misaligning. At the same time, the lower end face of the first mating part 42 completely disengages from the support of the abutment wall 15. Under the action of the first elastic element, the movable structure 4 moves downward to the first position, and the lower end face of the first mating part 42 enters the limiting groove 131. The first mating part 42 is locked downward into the limiting groove 131 to prevent the cutter head 1 from rotating relative to the mounting base 3. The restriction direction includes two rotation directions in the forward and reverse directions.

[0174] During disassembly, press the pressing part 41 upwards to move the movable structure 4 from the first position to the second position. The first mating part 42 disengages upwards from the limiting groove 131, and the second mating part 43 engages upwards in the anti-rotation groove 511. Rotate the cutter head 1 in the opposite direction relative to the mounting base 3. After the first hook 111 rotates circumferentially, it disengages from the second hook 311.
