Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a cutting tool structure and a food processing device using the structure. Background Technology

[0002] In today's fast-paced life, food processing equipment is widely used in home and commercial kitchens due to its high efficiency and convenience. These devices usually integrate multiple functions, among which the blade structure is one of the key components, directly related to the efficiency and safety of food processing. The blade structure in existing food processing equipment usually includes a rotating shaft, blade assembly, and fixed locking cover.

[0003] In these devices, the cutter assembly is mounted on a rotating shaft and securely held in place by a locking cover. This design aims to ensure that the cutter will not fall off the rotating shaft due to centrifugal force or other external forces during high-speed operation, thereby improving the safety and effectiveness of the equipment.

[0004] However, although the existing tool structure has certain rationality in its design, in actual use, the tool structure is usually designed to be used in both directions of rotation, and there is still a potential risk of the fixed locking cover falling off. Generally speaking, the fixed locking cover can only be subjected to force in one direction. Due to the high-speed rotation of the rotating shaft and the vibration during equipment use, when the rotating shaft rotates in the unlocking direction of the fixed locking cover, the fixed locking cover may rotate in the unlocking direction under certain conditions, causing the locking mechanism to fail. Once this happens, the fixed locking cover may release the lock on the tool assembly, thereby causing the fixed locking cover and the tool assembly to separate from the rotating shaft, which greatly increases the risk of equipment operation.

[0005] Furthermore, this rotation often occurs gradually, and users may not notice it immediately during use. This makes it easier for the tool to fall off during subsequent operations, which not only threatens user safety but may also damage the equipment, affecting its normal use and increasing maintenance and replacement costs.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0007] Regarding the aforementioned technical problem in the existing food processing equipment, the blade structure has a potential risk of the locking cover rotating in the unlocking direction during actual use. This could cause the locking cover and blade assembly to detach from the rotating shaft, greatly increasing the risk of equipment operation.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A cutting tool structure, comprising:

[0010] A rotating shaft, which is installed inside the food processing equipment;

[0011] A cutting tool assembly, which is mounted on the rotating shaft;

[0012] A locking cover is installed on the top of the rotating shaft and is screwed to the rotating shaft, which can restrict the tool assembly on the rotating shaft;

[0013] A locking structure is provided between a fixed locking cover and a rotating shaft. The locking structure includes a locking member and a locking part that can cooperate with the locking member. The locking part includes a rotating section and a latching section communicating with the rotating section. The rotating section allows the locking member to slide relative to it. The latching section allows the locking member in the rotating section to enter it, and the side wall of the latching section can abut against the side wall of the locking member to restrict the rotation of the fixed locking cover on the rotating shaft.

[0014] As described above, the tool structure further includes a linkage component that enables the locking member to remain within the snap-fit ​​section.

[0015] In the aforementioned tool structure, one end of the linkage component is connected to the fixed locking cover, and the latching section is located above or below the rotating section. When the locking member slides relative to the rotating section to the position where the rotating section has the latching section, the linkage component can drive the fixed locking cover to move upward relative to the rotating axis, so that the locking member moves relative to the latching section.

[0016] In one of the tool structures described above, the other end of the linkage component is connected to the rotating shaft; or, the other end of the linkage component is connected to the tool assembly.

[0017] In the tool structure described above, the locking component includes a first locking block disposed on the outer wall of the rotating shaft, the rotating section includes a first rotating groove disposed on the inner wall of the fixed lock cover, the first rotating groove is provided with a first entrance for the first locking block to move into it, and the latching section includes a first positioning groove disposed on the first rotating groove.

[0018] In the tool structure described above, the locking part further includes a guide section, one end of which is connected to a first inlet and another end of which is connected to a first rotating groove, and the first inlet is located at the other end of the guide section.

[0019] In the aforementioned tool structure, the locking component includes a second locking block disposed on the inner sidewall of the fixed locking cover, the rotating section includes a second rotating groove disposed on the outer sidewall of the rotating shaft, the second rotating groove is provided with a second inlet for the second locking block to move into it, and the latching section includes a second positioning groove disposed on the rotating shaft.

[0020] As described above, in a tool structure, the rotating shaft includes a shaft body and a locking cover fixing part disposed on the top of the shaft body. The second rotating groove is located below the locking cover fixing part. A flat part is provided on the side wall of the locking cover fixing part, and the second inlet is located at the flat part. The second positioning groove is disposed on the locking cover fixing part.

[0021] In the aforementioned tool structure, the locking member further includes a limiting protrusion, and the second locking block is disposed above the limiting protrusion. When the second locking block moves relative to the second positioning groove, the top of the limiting protrusion abuts against the bottom of the locking cover fixing part.

[0022] A food processing device includes a housing and a blade structure as described in any of the above claims, wherein the housing has a food processing chamber and the rotating shaft is located within the food processing chamber.

[0023] The beneficial effects of the utility model are:

[0024] This utility model relates to a cutting tool structure and a food processing device using the same structure, belonging to the field of mechanical technology. The cutting tool structure includes a rotating shaft, a cutting tool assembly, a fixed locking cover, and a locking structure. The locking structure is located between the fixed locking cover and the rotating shaft. The locking structure includes a locking member and a locking part that can cooperate with the locking member. The locking part includes a rotating section and a latching section communicating with the rotating section. The rotating section allows the locking member to slide relative to it. Specifically, the locking structure forms a double locking mechanism through the cooperation of the locking member and the locking part. When the locking member slides in the rotating section, it can enter the latching section at an appropriate position to lock the fixed locking cover. Furthermore, the side wall of the latching section can abut against the side wall of the locking member, which can effectively prevent the fixed locking cover from rotating due to external force or misoperation during operation, reducing the risk of the cutting tool assembly disengaging from the rotating shaft.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figures 1 to 5 As shown, a cutting tool structure in this embodiment includes:

[0038] Rotating shaft 1 is installed inside the food processing equipment;

[0039] The tool assembly 2 is mounted on the rotating shaft 1;

[0040] A fixed locking cover 3 is installed on the top of the rotating shaft 1 and is screwed to the rotating shaft 1, which can restrict the tool assembly 2 to the rotating shaft 1;

[0041] A locking structure 4 is disposed between the fixed locking cover 3 and the rotating shaft 1. The locking structure 4 includes a locking member 41 and a locking part 42 that can cooperate with the locking member 41. The locking part 42 includes a rotating section 421 and a latching section 422 that communicates with the rotating section 421. The rotating section 421 allows the locking member 41 to slide relative to it. The latching section 422 allows the locking member 41 in the rotating section 421 to enter it, and the side wall of the latching section 422 can abut against the side wall of the locking member 41 to restrict the rotation of the fixed locking cover 3 on the rotating shaft 1.

[0042] Specifically, the locking structure 4 forms a double locking mechanism through the cooperation of the locking member 41 and the locking part 42. When the locking member 41 slides in the rotating section 421, it can enter the latching section 422 at an appropriate position to lock the fixed cover 3. Furthermore, the side wall of the latching section 422 can abut against the side wall of the locking member 41, which can effectively prevent the fixed cover 3 from rotating due to external force or misoperation during operation. By preventing the fixed cover 3 from rotating, the risk of the tool assembly 2 disengaging from the rotating shaft 1 is significantly reduced, thereby improving the safety of equipment operation.

[0043] Furthermore, the locking structure 4 is designed separately from the fixed lock cover 3 and the rotating shaft 1, which makes it easier to replace and maintain each part, thus improving the maintainability of the equipment.

[0044] Furthermore, the design of the locking structure 4 simplifies the user's operation process. When installing and removing the tool, the user only needs to install it according to the prescribed method and simply rotate the fixing cover 3 to the corresponding position. No additional complicated tools or steps are required, making the operation process simpler and lowering the threshold for use.

[0045] Preferably, when the user rotates the fixed locking cover 3 to the locked position, the locking member 41 can enter the latching section 422 and approach or abut against the side wall of the latching section 422. When the fixed locking cover 3 tends to rotate on the rotating shaft 1, the locking member 41 can abut against the side wall of the latching section 422. This design ensures the fixed connection between the fixed locking cover 3 and the rotating shaft 1, preventing the fixed locking cover 3 from rotating when fixed. Through an effective locking mechanism, the fixed locking cover 3 is prevented from loosening due to rotation. In this way, the tool assembly 2 will not fall off due to an insecure connection when operating at high speed, significantly reducing the safety risks to the operator and the environment.

[0046] like Figures 1 to 5 As shown, the tool structure of this embodiment also includes a linkage component, which enables the locking member 41 to remain within the latching section 422.

[0047] Specifically, the main function of the linkage component is to ensure that the locking component 41 is always kept within the snap-fit ​​section 422, thereby maintaining a stable connection between the fixed lock cover 3 and the rotating shaft 1.

[0048] Preferably, when the locking member 41 moves through the rotating section 421, the linkage component can monitor its position in real time, and when the locking member 41 tends to leave the latching section 422, it can automatically push the locking member 41 back into the latching section 422 through a mechanical spring, gear or other form of connection to ensure that it is always in the locked state.

[0049] Furthermore, by using the linkage component to keep the locking member 41 within the latch section 422, it is possible to further prevent the lock cover 3 from being accidentally loosened, providing additional safety, especially under high-speed operation or high load conditions.

[0050] Furthermore, the linkage component ensures that the locking component 41 will not accidentally disengage from the latching section 422, thereby enhancing the stability of the entire tool structure and reducing potential malfunctions during operation.

[0051] Furthermore, the automated design of the linkage components reduces user intervention during operation. Users only need to focus on the normal use of the tool without constantly worrying about the locked state, thereby improving the user experience.

[0052] Preferred, such as Figures 1 to 5 As shown, in this embodiment, one end of the linkage component is connected to the fixed lock cover 3, and the other end of the linkage component is connected to the rotating shaft 1; or, the other end of the linkage component is connected to the tool assembly 2, and a suitable design can be selected according to actual needs.

[0053] like Figures 1 to 5 As shown, in this embodiment, the latching segment 422 is located above or below the rotating segment 421. This design ensures that the locking member 41 can smoothly slide to the position of the latching segment 422 during the movement of the rotating segment 421. When the locking member 41 slides relative to the rotating segment 421 to the position where the latching segment 422 is located, the linkage component can drive the fixed lock cover 3 to move upward relative to the rotating shaft 1, so that the locking member 41 moves relative to the latching segment 422, thereby achieving effective locking.

[0054] This design greatly simplifies the locking process. Through the action of the linkage component, the user only needs to rotate the fixed lock cover 3 on the rotating shaft 1 to drive the locking component 41 to slide in the rotating section 421 and automatically move into the latching section 422 to automatically lock. There is no need for manual adjustment or fixing, which effectively improves the operating efficiency, reduces the user's operating burden, and enhances the user experience.

[0055] Specifically, the upward movement of the fixed locking cover 3 relative to the rotating shaft 1 ensures that the locking component 41 is firmly locked in the snap-fit ​​section 422, reducing the risk of accidental detachment due to improper operation and improving the overall safety of the equipment.

[0056] like Figures 1 to 5 As shown, the locking component 41 of this embodiment includes a first locking block disposed on the outer side wall of the rotating shaft 1, the rotating section 421 includes a first rotating groove disposed on the inner side wall of the fixed lock cover 3, the first rotating groove is provided with a first entrance for the first locking block to move into it, and the latching section 422 includes a first positioning groove disposed on the first rotating groove.

[0057] Specifically, the design of the first entry point allows users to operate more intuitively when locking or unlocking, ensuring that the first locking block moves smoothly into or out of the first rotating groove, reducing the complexity of operation; the design of the first rotating groove on the inner wall of the fixed lock cover 3 can provide a specified movement path for the first locking block; the design of the first positioning groove on the first rotating groove can ensure that the locking component 41 can be accurately positioned and fixed during operation.

[0058] like Figures 1 to 5 As shown, the locking part 42 in this embodiment also includes a guide section 423, one end of which is connected to the first rotating groove, and the first inlet 424 is located at the other end of the guide section 423.

[0059] This design makes the movement trajectory of the locking component 41 clearer and smoother. The presence of the guide section 423 can reduce possible misoperation during locking and unlocking, reduce the risk of accidental detachment, and ensure the safety of the equipment during use.

[0060] Specifically, in this embodiment, the guide section 423 provides guidance for the first locking block to enter the first rotating groove, so that when the user assembles the fixed locking cover 3 on the rotating shaft 1, the first locking block can be aligned and inserted through the first inlet 424. With clear guidance, this guidance not only makes the block enter the groove more smoothly, but also ensures the efficiency of the assembly process, reduces the operational difficulties caused by improper alignment, simplifies the user's operation steps, and reduces the complexity of assembly.

[0061] This easy-to-align design allows users to quickly complete the installation when assembling the locking cover 3, reducing the time and effort required for operation and improving the overall user experience.

[0062] The presence of guide section 423 significantly reduces the risk of misoperation due to improper alignment, ensuring that the first locking block can smoothly enter the correct position, thereby improving the accuracy and safety of assembly.

[0063] Preferably, the linkage component in this embodiment includes an elastic element, and the fixing lock cover 3 has an assembly space 5 for assembling the elastic element. The fixing lock cover 3 has a dedicated assembly space 5 to accommodate the elastic element. This space design allows the elastic element to be installed smoothly and operate stably.

[0064] Preferably, in this embodiment, one end of the elastic element abuts against the top of the assembly space 5, and the other end abuts against the top of the rotating shaft 1. This design makes the structure more compact and is conducive to miniaturizing the size of the tool structure.

[0065] Preferably, the elastic element can be made of elastic springs or silicone or other components, and a suitable design can be selected according to actual needs.

[0066] Specifically, in this embodiment, when the user assembles the fixed locking cover 3 onto the rotating shaft 1 on which the tool assembly 2 is mounted, it first aligns with the first locking block through the first inlet 424, so that the first locking block enters the guide section 423 through the first inlet 424. Then, the fixed locking cover 3 is continuously pressed down so that the first locking block slides to the connection between the guide section 423 and the first rotating groove. At this time, the elastic element in the assembly space 5 is in a compressed state.

[0067] At this time, rotating the fixed lock cover 3 causes the first locking block to slide in the first rotating groove. When it slides to the position where the first rotating groove has the first positioning groove, the downward pressure on the fixed lock cover 3 is removed. At this time, the elastic element deforms elastically and pushes the fixed lock cover 3 upward to drive the first locking block into the first positioning groove, thereby realizing the locking between the fixed lock cover 3 and the rotating shaft 1.

[0068] When it is necessary to remove the fixed locking cover 3 from the rotating shaft 1, the fixed locking cover 3 needs to be pressed down again to make the first locking block exit the first positioning groove. At this time, the elastic element is compressed again and the fixed locking cover 3 is rotated, thereby driving the first locking block to slide in the first rotating groove. When it slides to the connection between the first rotating groove and the guide section 423, the downward pressure on the fixed locking cover 3 is released. At this time, the elastic element deforms elastically and pushes the fixed locking cover 3 upward to drive the first locking block into the guide section 423. The first locking block can exit the guide section 423 from the first inlet 424, thereby realizing the disassembly between the fixed locking cover 3 and the rotating shaft 1.

[0069] Specifically, the design structure of the guide section 423 can effectively limit the movement range of the fixed lock cover, ensuring that the fixed lock cover will not immediately detach from the rotating shaft 1 due to elastic deformation. It needs to be lifted a certain distance to completely detach the fixed lock cover from the rotating shaft 1, ensuring the loading and unloading path of the fixed lock cover on the rotating shaft 1.

[0070] Preferably, in this embodiment, the lowest point of the first positioning groove is lower than the lowest point of the first rotating groove, that is, the first positioning groove is located below the first rotating groove. This allows the first positioning groove to slide to the position where the first rotating groove has the first positioning groove, and the downward pressure on the fixed locking cover 3 is removed. At this time, the elastic element deforms elastically and pushes the fixed locking cover 3 upward. The first locking block can move downward into the first positioning groove, which has the advantages of simple structure and convenient operation.

[0071] Preferably, in some other embodiments, the lowest point of the first positioning groove is higher than the highest point of the first rotating groove, that is, the first positioning groove is located above the first rotating groove, so that when the first rotating groove is slid to the position where the first positioning groove is located, the downward pressure on the fixed locking cover 3 is removed, and the elastic element elastically deforms and pushes the fixed locking cover 3 upward, and the first locking block can move relatively upward into the first positioning groove. A suitable design can be selected according to actual needs.

[0072] like Figures 1 to 5 As shown, a food processing device according to this embodiment includes a housing 100 and a blade structure as described in any of the above. The housing 100 is provided with a food processing cavity 101, and the rotating shaft 1 is located in the food processing cavity 101. By adopting the above-described blade structure, the food processing device can effectively prevent the fixed locking cover 3 from rotating due to external force or misoperation during operation. By preventing the rotation of the fixed locking cover 3, the risk of the blade assembly 2 disengaging from the rotating shaft 1 is significantly reduced, thereby improving the safety of the device operation.

[0073] Preferably, in this embodiment, the tool assembly 2 and the rotating shaft 1 are connected by a non-circular mesh transmission.

[0074] Preferably, in other embodiments, the tool structure does not include a linkage component. The locking member 41 and the latching section 422 are fixedly connected by a snap-fit ​​connection. When the user assembles the fixed locking cover 3 onto the rotating shaft 1 on which the tool assembly 2 is mounted, the locking member 41 can be assembled into the rotating section 421. Then, the fixed locking cover 3 is rotated, thereby causing the locking member 41 to slide within the rotating section 421. When it slides to the position where the rotating section 421 has the latching section 422, force can be applied to the fixed locking cover 3 to make the locking member 41 snap into the latching section 422, thereby achieving the locking of the locking member 41 and the latching section 422, and realizing the locking between the fixed locking cover 3 and the rotating shaft 1.

[0075] When it is necessary to remove the fixed locking cover 3 from the rotating shaft 1, a reverse force is applied to the fixed locking cover 3 to cause the locking member 41 to disengage from the snap-fit ​​section 422 and move into the rotating section 421. Rotating the fixed locking cover 3 causes the locking member 41 to slide within the rotating section 421. When rotated to the designated position, the locking member 41 can disengage from the rotating section 421, thereby achieving the disassembly of the fixed locking cover 3 from the rotating shaft 1. Preferably, the snap-fit ​​section 422 can be located on one side, above, or below the rotating section 421. The above design allows for a more compact tool structure design, effectively reducing the size of the tool structure. A suitable design can be selected according to actual needs.

[0076] Example 2:

[0077] like Figures 6 to 9As shown, the locking component 41 of this embodiment includes a second locking block 411 disposed on the inner side wall of the fixed lock cover 3, the rotating section 421 includes a second rotating groove disposed on the outer side wall of the rotating shaft 1, the second rotating groove is provided with a second entrance for the second locking block 411 to move into it, and the latching section 422 includes a second positioning groove disposed on the rotating shaft 1.

[0078] Specifically, the second locking block 411 is disposed on the inner side wall of the fixed lock cover 3, and can cooperate with the rotating section 421 and the latching section 422 of the rotating shaft 1 during operation to realize the locking and unlocking functions.

[0079] The second rotating groove is located on the outer side wall of the rotating shaft 1, providing a sliding and moving track for the second locking block 411. This design allows the second locking block 411 to move freely within the second rotating groove during rotation, ensuring the reliability of the lock.

[0080] Preferably, the second inlet located on the second rotating groove provides a channel for the second locking block 411 to enter the rotating groove, facilitating its locking in a suitable position.

[0081] Preferably, the second positioning groove is provided on the rotating shaft 1 as part of the snap-fit ​​section 422, and can cooperate with the second locking block 411 to ensure the stability of the locking and ensure that the locking will not fail due to external force during operation.

[0082] Preferably, the cooperation between the second locking block 411 and the second rotating groove provides a specified movement path for the installation and removal of the fixed locking cover 3 on the rotating shaft 1. Furthermore, the cooperation between the second locking block 411 and the second positioning groove can effectively prevent the fixed locking cover 3 from rotating on the rotating shaft 1 during operation, thus preventing accidental loosening and reducing the risk of the tool assembly 2 falling off, thereby improving the safety of the equipment.

[0083] like Figures 6 to 9 As shown, the rotating shaft 1 in this embodiment includes a shaft body 11 and a locking cover fixing part 12 provided on the top of the shaft body 11. The second rotating groove is located below the locking cover fixing part 12. A flat part 121 is provided on the side wall of the locking cover fixing part 12, and the second inlet is located at the flat part 121. The second positioning groove is provided on the locking cover fixing part 12.

[0084] Specifically, by moving the second locking block 411 above the flat position 121, during the locking operation, the second locking block 411 is pushed from the flat position 121 into the second rotating groove. Then, the fixed lock cover 3 is rotated so that the second locking block 411 moves from the second rotating groove to the bottom of the second positioning groove and is aligned with the second positioning groove. Then, the fixed lock cover 3 is moved upward so that the second locking block 411 moves into the second positioning groove, thereby achieving the locking of the fixed lock cover 3 on the rotating shaft 1.

[0085] Preferably, the second rotating groove is located below the locking cover fixing part 12, providing a space that can interact with the second locking block 411, so that locking and unlocking can be smoothly achieved during rotation.

[0086] Furthermore, the side wall of the locking cover fixing part 12 is provided with a flat part 121, which is the position of the second entrance. The design of the flat part makes it easier for the second locking block 411 to enter the second rotating groove, making the operation simpler and reducing the difficulty of operation for the user.

[0087] like Figures 6 to 9 As shown, the locking member 41 in this embodiment also includes a limiting protrusion 412. The second locking block 411 is disposed above the limiting protrusion 412. When the second locking block 411 moves into the second positioning groove, the top of the limiting protrusion 412 abuts against the bottom of the lock cover fixing part 12, so as to further limit the upward movement distance of the fixed lock cover 3 on the rotating shaft 1, and reduce the force on the second locking block 411, thus extending the service life of the locking member 41.

[0088] Furthermore, the top of the limiting protrusion 412 abuts against the bottom of the locking cover fixing part 12, and the contact during the locking process can provide the user with obvious sensory feedback, making the operation more intuitive and increasing the user's confidence in the operation.

[0089] Specifically, in this embodiment, when the user assembles the fixed locking cover 3 onto the rotating shaft 1 on which the tool assembly 2 is mounted, the limiting protrusion 412 is first aligned with the flat part 121, so that the limiting protrusion 412 enters the second rotating groove through the second inlet. Then, the fixed locking cover 3 is continuously pressed down so that the limiting protrusion 412 and the second locking block 411 are completely inserted into the second rotating groove. At this time, the elastic element in the assembly space 5 is in a compressed state.

[0090] The user can rotate the fixed lock cover 3, thereby causing the limiting protrusion 412 and the second locking block 411 to slide within the second rotating groove until the lock cover fixing part 12 covers the second locking block 411. At this point, the downward pressure on the fixed lock cover 3 can be removed, and the elastic element will elastically deform, pushing the fixed lock cover 3 upward so that the top of the second locking block 411 abuts against the bottom of the lock cover fixing part 12. Continue to rotate the fixed lock cover 3. When the second locking block 411 moves to the second positioning groove, the elastic element will elastically deform again, pushing the fixed lock cover 3 upward again, so that the second locking block 411 is engaged in the second positioning groove. When the top of the limiting protrusion 412 abuts against the bottom of the lock cover fixing part 12, it means that the second locking block 411 is fully engaged in the second positioning groove, thereby achieving the locking between the fixed lock cover 3 and the rotating shaft 1.

[0091] When it is necessary to remove the fixed lock cover 3 from the rotating shaft 1, the fixed lock cover 3 needs to be pressed down to make the second locking block 411 exit the second positioning groove. At this time, the elastic element is compressed again and the fixed lock cover 3 is rotated, thereby driving the limiting protrusion 412 and the second locking block 411 to slide in the second rotating groove. After rotating a certain angle, the downward pressure on the fixed lock cover 3 can be removed. The elastic element deforms elastically and pushes the fixed lock cover 3 upward so that the top of the second locking block 411 abuts against the bottom of the lock cover fixing part 12. The fixed lock cover 3 is rotated continuously. When the limiting protrusion 412 moves to the position of the flat part 121, that is, when the limiting protrusion 412 no longer abuts against the lock cover fixing part 12, the elastic element deforms elastically again and pushes the fixed lock cover 3 upward again so that the limiting protrusion 412 exits the second rotating groove through the second opening, thereby realizing the disassembly of the fixed lock cover 3 from the rotating shaft 1.

[0092] Preferably, in other embodiments, the tool structure does not include a linkage component. The second locking block 411 and the second positioning groove are fixedly connected by a snap-fit ​​connection. When the user assembles the fixed locking cover 3 on the rotating shaft 1 on which the tool assembly 2 is mounted, the fixed locking cover 3 can be rotated to the position where the second locking block 411 and the second positioning groove are aligned, and then the fixed locking cover 3 can be lifted up again to make the second locking block 411 engage with the second positioning groove, thereby locking the fixed locking cover 3 and the rotating shaft 1.

[0093] When it is necessary to remove the fixed locking cover 3 from the rotating shaft 1, push the fixed locking cover 3 down to make the second locking block 411 exit the second positioning groove, and then rotate the fixed locking cover 3 to achieve the disassembly between the fixed locking cover 3 and the rotating shaft 1. The above design can make the tool structure design more compact and effectively reduce the volume of the tool structure. The appropriate design can be selected according to actual needs.

[0094] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
