Description

Technical Field

[0001] This invention belongs to the technical field of nursing tools, specifically a universal rotating mechanism and a razor. Background Technology

[0002] There are many ways to shave, including electric and manual razors. Electric razors are efficient and convenient, while manual razors offer greater satisfaction. When an electric razor doesn't shave all the stubble, a manual razor is needed. Therefore, the value and significance of manual razors make them an indispensable item for many, especially men. Furthermore, replacing the head of an electric razor is far less convenient than replacing the head of a manual razor.

[0003] Many men have long felt that manual razors offer a better shave than electric razors, primarily because manual razors follow the hairline more closely, resulting in fewer short hairs and a cleaner shave. However, current manual razors still have some unavoidable drawbacks, such as the lack of omnidirectional adjustment and gaps between the blades and the shaving head, preventing the blades from fully engaging with the hairline. Therefore, manual adjustment is required, reducing the efficiency of manual shaving. Summary of the Invention

[0004] The purpose of this invention is to improve the problem that manual shavers cannot be adjusted in all directions, and to provide a universal rotation mechanism and a shaver.

[0005] The technical solutions for achieving the above objectives include the following:

At least a portion of the rotating component is located on the outer surface of the housing. The stabilizer is located in the movable cavity, with a first end of the stabilizer mounted on the housing and a second end of the stabilizer mounted on the rotating component.

[0011] The outer casing has a first opening, and the second limiting part or the third limiting part is located at the first opening, and the second limiting part and the third limiting part are disposed opposite to each other. The second limiting part and the third limiting part are used to be located on the outer surface of the universal ball.

[0012] The arc of both the second limiting part and the third limiting part is 0 degrees to 30 degrees.

[0013] In one embodiment, the pushing member includes a push rod and a connecting block, the push rod and the connecting block are an integral structure, the push rod is at least partially located in the mounting cavity and slides in cooperation with the second mounting groove of the mounting cavity; the connecting block is located in the movable cavity and has a fourth limiting part, the fourth limiting part is used to abut against the inner wall of the outer shell; the fourth limiting part is disposed opposite to the first limiting part.

[0014] In one embodiment, the housing has a second opening, and the first opening, the arcuate groove, and the second opening of the housing are sequentially connected; at least a portion of the omnidirectional ball is located at the first opening and the second opening, and the width of both the first opening and the second opening is smaller than the diameter of the omnidirectional ball.

[0015] In one embodiment, at least a portion of the housing is spherical, and the outer surface of the housing near the first opening is arc-shaped.

[0016] In one embodiment, the stabilizer includes a connecting rod, a first elastic element, and a second elastic element. A first end of the first elastic element is mounted on a first end of the connecting rod, and a first end of the second elastic element is mounted on a second end of the connecting rod. The second ends of both the first and second elastic elements are mounted on a housing, and the first and second elastic elements are arranged opposite to each other. The connecting rod is detachably mounted on a rotating assembly.

[0017] In one embodiment, the connecting block of the rotating assembly has a hook groove located at the bottom of the connecting block, and the connecting rod is installed in the hook groove;

[0018] The connecting rod forms a U-shaped groove with the first elastic member and the second elastic member on both sides.

[0019] In one embodiment, the first elastic member has a first hook, the second elastic member has a second hook, and the housing has a first connecting post and a second connecting post, the first connecting post and the second connecting post being disposed opposite to each other, the first hook cooperating with the first connecting post, and the second hook cooperating with the second connecting post.

[0020] In one embodiment, the outer shell includes a first shell and a second shell, the first shell having a limiting block and the second shell having a second limiting groove that engages with the limiting block;

[0023] The technical solution provided by this invention has the following advantages and effects:

[0024] An arc-shaped groove is provided inside the outer casing to house the rotating component, which then rotates and engages with the inner wall of the casing. This rotating component connects to the blade head mechanism. When the blade head mechanism is fixed to the rotating component, the pressure applied to the blade head mechanism will cause the rotating component to move, thus improving the problem of manual shavers not being able to adjust in all directions. At least a portion of the rotating component is located on the outer surface of the outer casing to prevent the blade head mechanism from abutting against the outer wall of the casing, thereby preventing the casing from restricting the rotation of the blade head mechanism. Furthermore, this rotating component is also connected to a stabilizer, which is installed inside the outer casing and located within a movable cavity. The stabilizer has a certain amount of space to move within the movable cavity, and when the rotating component rotates, at least a portion of it engages with the stabilizer within the movable cavity. During use, the shaving head mechanism contacts the contact surface. As the shaving head mechanism rotates, a force is applied to the stabilizer via the rotating component. The stabilizer, in turn, applies a counterforce to the rotating component, preventing the shaving head mechanism from wobbling or rotating too much, thus improving the stability of the rotating component. When the force acting on the rotating component is greater than or less than the counterforce of the stabilizer, the rotating component rotates. The force acting on the rotating component and the counterforce applied by the stabilizer keep the rotating component in a relatively balanced or stable state, allowing the user to shave the beard on the contact surface while rotating the shaving head mechanism. Since shaving involves micro-operations, the wobbling of the rotating component and the control of the rotation arc are particularly important. Therefore, this stabilizer improves the safety of shaving operations. After using the razor, the rotating component is returned to its initial state by the stabilizer for the next use.

[0048] Example 1

[0049] like Figures 1 to 6As shown, a universal rotating mechanism 100 includes: a rotating component 20, a stabilizer 40, and a housing 10. The housing 10 has an arc-shaped groove 12 and a movable cavity 13, with the arc-shaped groove 12 communicating with the movable cavity 13. The rotating component 20 is at least partially located within the arc-shaped groove 12 and rotatably engages with the housing 10. At least a portion of the rotating component 20 is located on the outer surface of the housing 10. The stabilizer 40 is located within the movable cavity 13, with its first end mounted on the housing 10 and its second end mounted on the rotating component 20. By providing the arc-shaped groove 12 within the housing 10, the rotating component 20 is positioned within the arc-shaped groove 12 and rotatably engages with the inner wall of the housing 10. This rotating component 20 is used to connect to a blade head mechanism 210. When the blade head mechanism 210 is fixed to the rotating component 20, the blade head mechanism 210, when compressed, will drive the rotating component 20 to move, thus improving the problem of the manual shaver 200's inability to be universally adjustable. At least a portion of the rotating assembly 20 is located on the outer surface of the housing 10 to prevent the cutting head mechanism 210 from abutting against the outer wall of the housing 10, thereby preventing the housing 10 from restricting the rotation of the cutting head mechanism 210; moreover, this rotating assembly 20 is also connected to the stabilizer 40, which is installed inside the housing 10 and located in the movable cavity 13. The stabilizer 40 has a certain amount of space to move within the movable cavity 13. When the rotating assembly 20 rotates, at least a portion of it cooperates with the stabilizer 40 within the movable cavity 13.

[0050] During use, the shaving head mechanism 210 contacts the contact surface. As the shaving head mechanism 210 rotates, a force is applied to the stabilizer 40 via the rotating component 20. The stabilizer 40 applies a counterforce to the rotating component 20, preventing the shaving head mechanism 210 from swaying or rotating too much, thus improving the stability of the rotating component 20. When the force acting on the rotating component 20 is greater than or less than the counterforce of the stabilizer 40, the rotating component 20 rotates. The force acting on the rotating component 20 and the counterforce applied by the stabilizer 40 keep the rotating component 20 in a relatively balanced or stable state, allowing the user to shave the beard on the contact surface while rotating the shaving head mechanism 210. Since shaving involves micro-operations, the swaying of the rotating component 20 and the control of its rotation arc are particularly important. Therefore, the stabilizer 40 improves the safety of the shaving operation. After using the razor 200, the rotating component 20 is returned to its initial state by the stabilizer 40 for the next use.

[0051] In this embodiment, the blade head mechanism 210 directly cooperates with the rotating component 20, and its rotational joint is located relatively close to the blade head mechanism 210, compared to some shavers 200s that place the rotational joint at the handle 220. When using the shaver 200 of this invention, the blade head mechanism 210 can fit into the contact surface by slightly swinging at a certain angle. The rotation arc of the blade head mechanism 210 of this shaver 200 is more precise and sensitive, with high operational accuracy, reducing the gap between it and the contact surface, making the blade fit the beard root more closely, and resulting in a cleaner shave with the shaver 200 equipped with the universal rotating mechanism 100, improving shaving efficiency and enhancing the user experience.

[0052] To further improve the stability of the cutter head mechanism 210 during rotation, such as... Figures 2 to 5 As shown, the rotating assembly 20 includes a swivel ball 201 and a pusher 30. The swivel ball 201 is at least partially located in the arc-shaped groove 12 and slides against the inner wall of the housing 10. The swivel ball 201 has a mounting cavity 21 that extends from one end of the swivel ball 201 to the other end. The first end of the pusher 30 is installed in the mounting cavity 21, and the second end of the pusher 30 abuts against the outer wall of the swivel ball 201. The second end of the pusher 30 is also installed on the stabilizer 40. The omnidirectional ball 201 can rotate freely by sliding its outer arc surface with the inner arc surface of the outer shell 10, and its rotation direction is not restricted during rotation. The omnidirectional ball 201 has a mounting cavity 21 for fixing the mounting rod 230 of the cutter head mechanism 210. The mounting rod 230 of the cutter head mechanism 210 is engaged with a part of the mounting cavity 21, and the other part of the mounting cavity 21 is used to accommodate the push rod 31. When the omnidirectional ball 201 is rotated by the mounting rod 230, the push rod 31 rotates with the omnidirectional ball 201 and pulls the stabilizer 40. The push rod 31 is connected to the stabilizer 40. When the mounting rod 230 is adjusted, it acts on the stabilizer 40 through the push rod 31. The stabilizer 40 applies a reaction force, which further improves the stability of the cutter head mechanism 210 during rotation.

[0053] To further limit the rotation angle of the omnidirectional ball 201. For example... Figure 5 and Figure 6As shown, the omnidirectional ball 201 has a first limiting part 22, a second limiting part 23 and a third limiting part 24. At least a portion of the first limiting part 22 is located inside the movable cavity 13, and the first limiting part 22 is used to abut against the inner wall of the outer shell 10. When the first limiting part 22 abuts against the inner wall of the outer shell 10, the omnidirectional ball 201 will be unable to continue to rotate upward. The first limiting part 22 is used to limit the rotation angle of the omnidirectional ball 201 in the movable cavity 13, and the direction of its restriction is mainly at the top position of the movable cavity 13. The outer casing 10 has a first opening 11, and the second limiting part 23 or the third limiting part 24 is located at the first opening 11, with the second limiting part 23 and the third limiting part 24 being disposed opposite to each other. The second limiting part 23 and the third limiting part 24 are used to be located on the outer surface of the universal ball 201. When the mounting rod 230 of the cutting head mechanism 210 is installed in the first mounting groove 211, the cutting head mechanism 210 drives the universal ball 201 to rotate upward to a first distance, and its mounting rod 230 will abut against the inner wall of the outer casing 10. The second limiting part 23 restricts the upward adjustment angle of the cutting head mechanism 210. When the cutting head mechanism 210 drives the universal ball 201 to rotate downward to a first distance, its mounting rod 230 will also abut against the inner wall of the outer casing 10. The second limiting part 23 restricts the downward adjustment angle of the cutting head mechanism 210. To prevent the blade mechanism 210 from rotating too much, reduce the distance that the pusher 30 pulls on the stabilizer 40, and prevent the stabilizer 40 from experiencing mechanical fatigue or failure due to excessive extension and retraction distance.

[0054] Furthermore, by limiting the rotation angle of the universal ball 201 through the first limiting part 22, the second limiting part 23, and the third limiting part 24, the blade head mechanism 210 is always in a state of local micro-adjustment. If a large angle adjustment of the blade head mechanism 210 is required, the overall position of the shaver 200 can be moved by rotating the handle 220 of the shaver 200. By adjusting the blade head mechanism 210 of the shaver 200 through local micro-adjustment, the rotating component 20 is further kept in a balanced or stable state, making it convenient for the user to shave the beard on the contact surface while rotating the blade head mechanism 210.

[0055] In this embodiment, the second limiting part 23 and the third limiting part 24 are located on the outer wall of the universal ball 201, and the second limiting part 23 or the third limiting part 24 extends circumferentially along the first mounting groove 211.

[0056] Furthermore, the arc 25 of both the second limiting part 23 and the third limiting part 24 is between 0 and 30 degrees. When the mounting rod 230 of the cutter head mechanism 210 is installed in the first mounting groove 211, the upward rotation angle of the mounting rod 230 will be limited to the range of 0 to 30 degrees, and the downward rotation angle of the mounting rod 230 will also be limited to the range of 0 to 30 degrees. Therefore, the rotation angle of the cutter head mechanism 210 on the outer surface of the housing 10 will not exceed 60 degrees, exceeding the range of motion of the mounting rod 230. The mounting rod 230 will be restricted by the housing 10, further limiting the rotation angle of the cutter head mechanism 210.

[0057] To prevent the omnidirectional ball 201 from sliding out of the housing 10. Figure 5 As shown, the outer casing 10 has a second opening 14, and the first opening 11, the arc-shaped groove 12, and the second opening 14 are sequentially connected. At least a portion of the universal ball 201 is located at the first opening 11 and the second opening 14, and the widths of both the first opening 11 and the second opening 14 are smaller than the diameter of the universal ball 201. By making the widths of the first opening 11 and the second opening 14 smaller than the diameter of the universal ball 201, the universal ball 201 cannot be removed from the first opening 11 and the second opening 14 without opening the outer casing 10. The universal ball 201 is confined within the arc-shaped groove 12 of the outer casing 10, further improving the stability of the universal ball 201 within the outer casing 10. Simultaneously, the first opening 11 also facilitates the passage and installation of the mounting rod 230 within the first mounting groove 211.

[0058] To prevent the housing 10 from obstructing the rotation of the cutting head mechanism 210 on the outer surface of the housing 10, such as... Figures 1 to 5 As shown, at least a portion of the outer casing 10 is spherical, and the outer surface of the outer casing 10 near the first opening 11 is arc-shaped. By setting the outer casing 10 to a spherical shape and making its outer surface arc-shaped, its cutting head mechanism 210 is generally elongated. When the cutting head mechanism 210 is engaged with the universal ball 201, the inner side of the cutting head mechanism 210 is always tangent to the outer surface of the outer casing 10, thus preventing the outer surface of the outer casing 10 from obstructing the cutting head mechanism 210.

[0059] To further improve the stability of the omnidirectional ball 201 during rotation. For example... Figure 7 and Figure 9As shown, the stabilizer 40 includes a connecting rod 45, a first elastic element 41, and a second elastic element 42. The first end of the first elastic element 41 is mounted on the first end of the connecting rod 45, and the first end of the second elastic element 42 is mounted on the second end of the connecting rod 45. The second ends of both the first elastic element 41 and the second elastic element 42 are mounted on the housing 10, and the first elastic element 41 and the second elastic element 42 are arranged opposite to each other. The connecting rod 45 is detachably mounted on the rotating assembly 20. By connecting the two ends of the connecting rod 45 to the first elastic element 41 and the second elastic element 42 respectively, both the first elastic element 41 and the second elastic element 42 are mounted on the housing 10. When the omnidirectional ball 201 pulls the stabilizer 40 through the pusher 30, the omnidirectional ball 201 moves to the left, pulling the first elastic element 41, and the first elastic element 41 applies a counteracting pulling force to the omnidirectional ball 201; the omnidirectional ball 201 moves to the right, pulling the second elastic element 42, and the second elastic element 42 applies a counteracting pulling force to the omnidirectional ball 201; when the omnidirectional ball 201 moves up and down, it simultaneously pulls the first elastic element 41 and the second elastic element 42, and the first elastic element 41 and the second elastic element 42 apply a counteracting force to the omnidirectional ball 201, thereby improving the stability of the omnidirectional ball 201 during rotational adjustment, and also driving the omnidirectional ball 201 to reset. Moreover, the connecting rod 45 is detachably mounted on the rotating assembly 20, which facilitates the installation and replacement of the stabilizer 40 and the rotating assembly 20.

[0060] To improve the stability of the connection between the pusher 30 and the stabilizer 40. For example... Figure 5 , Figure 8 as well as Figure 9 As shown, the connecting block 32 of the rotating assembly 20 has a hook groove 33 located at the bottom of the connecting block 32, and the connecting rod 45 is installed in the hook groove 33. By installing the connecting rod 45 in the groove 33 of the connecting block 32, at least a portion of the stabilizer 40 is engaged with the connecting block 32. Moreover, the connecting rod 45 forms a U-shaped groove 46 with the sides of the first elastic member 41 and the second elastic member 42. The groove 46 is used to accommodate at least a portion of the connecting block 32, so that the outer wall of the connecting block 32 abuts against the first elastic member 41 and the second elastic member 42 respectively. By placing the connecting block 32 of the rotating assembly 20 on the U-shaped slot 46, the outer walls on both sides of the connecting block 32 abut against the first elastic member 41 and the second elastic member 42 respectively. The first elastic member 41 and the second elastic member 42 clamp the two sides of the connecting block 32, thereby improving the structural compactness between the connecting block 32 and the first elastic member 41 and the second elastic member 42, and improving the stability of the connecting block 32 of the pusher 30 and the stabilizer 40.

[0061] To improve the stability of stabilizer 40, such as... Figures 2 to 4 , Figure 7 and Figure 9As shown, the first elastic element 41 has a first hook 43, and the second elastic element 42 has a second hook 44. The outer casing 10 contains a first connecting post 15 and a second connecting post 16, which are arranged opposite to each other. The first hook 43 engages with the first connecting post 15, and the second hook 44 engages with the second connecting post 16. By hanging the first hook 43 of the first elastic element 41 on the first connecting post 15 and the second hook 44 of the second elastic element 42 on the second connecting post 16, the hooks fit against the outer wall of the connecting post and hook onto the connecting post, improving the connection stability between the stabilizer 40 and the outer casing 10. Furthermore, since the first elastic element 41 is connected to the second elastic element 42 via the connecting rod 45, the first elastic element 41 and the second elastic element 42 are in a tensioned state after installation, thereby improving the stability of the first elastic element 41 and the second elastic element 42 within the movable cavity 13.

[0062] Example 2

[0063] For easy replacement of the cutter head mechanism 210. For example... Figure 5 As shown, the present invention also proposes a pushing mechanism, which includes a housing 10 and a pushing member 30. The housing 10 has a mounting cavity 21 extending from one side of the housing 10 to the other side. The mounting cavity 21 includes a first mounting groove 211 and a second mounting groove 212. The pushing member 30 is at least partially located in the second mounting groove 212 and slides with the second mounting groove 212. The pushing member 30 has a first moving position and a second moving position. In the first moving position, the first end of the pushing member 30 is located in the first mounting groove 211. In the second moving position, the first end of the pushing member 30 is away from the first mounting groove 211. The pusher 30 slides within the mounting cavity 21 by engaging with the second mounting groove 212. The first mounting groove 211 is used to mount the mounting rod 230 of the cutter head mechanism 210. After entering the first mounting groove 211, the mounting rod 230 engages with the outer casing 10. When the cutter head mechanism 210 needs to be replaced, the pusher 30 is moved from the second moving position to the first moving position, causing the pusher 30 to abut against the mounting rod 230. During this movement, the mounting rod 230 is pushed out of the first mounting groove 211, thereby allowing the cutter head mechanism 210 to move freely. The mounting rod 230 is separated from the housing 10. When installing a new blade head mechanism 210, the mounting rod 230 of the blade head mechanism 210 is inserted into the first mounting groove 211, thereby squeezing or pushing the pusher 30 from the first moving position to the second moving position, thus completing the replacement of the blade head mechanism 210. The pusher 30 pushes the blade head mechanism 210, causing the mounting rod 230 to separate from the housing 10, thus preventing the mounting rod 230 of the blade head mechanism 210 from being stuck by the housing 10 and improving the problem that the shaver 200 is often stuck when replacing the blade head mechanism 210.

[0064] To prevent the cutting head mechanism 210 from getting stuck inside the housing 10, the second end of the pushing member 30 is used to abut against the inner wall of the housing 10; the moving distance of the pushing member 30 is greater than or equal to the depth of the first mounting groove 211. When the pushing member 30 moves from the second moving position to the first moving position, at this time, the second end of the pushing member 30 is exactly abutting against the inner wall of the housing 10, and the pushing member 30 can no longer move. However, the moving distance of the pushing member 30 is greater than or equal to the depth of the first mounting groove 211. Therefore, when the pushing member 30 moves in the first mounting groove 211, it can completely push the mounting rod 230 of the cutting head mechanism 210 outside the first mounting groove 211, so that the mounting rod 230 is completely separated from the housing 10, further preventing the cutting head mechanism 210 from getting stuck inside the housing 10.

[0065] To improve the stability of the connection between the blade head mechanism 210 and the universal ball joint 201, the inner wall of the first mounting groove 211 has a first limiting groove 213, which extends circumferentially along the first mounting groove 211. This first limiting groove 213 is used to engage with the ridge 9 (not shown in the figure) of the mounting rod 230, thereby improving the stability of the connection between the blade head mechanism 210 and the universal ball joint 201 and preventing the blade head mechanism 210 from falling off during shaving.

[0066] To ensure proper installation of the cutting head mechanism 210, the cross-section of the first mounting groove 211 is either triangular or arched. When the apex of the first mounting groove 211 faces upwards, the shape of the mounting rod 230 matches the shape of the first mounting groove 211. Only when the apex of the mounting rod 230 corresponds to the apex of the first mounting groove 211 can the mounting rod 230 be inserted into the first mounting groove 211, with the apex facing upwards, allowing the cutting edge of the cutting head to shave. Therefore, the shape of the first mounting groove 211 can be used for positioning, ensuring proper installation of the cutting head mechanism 210 and improving the efficiency of its installation. Furthermore, the pusher 30 has a positioning part 34 that mates with the first mounting groove 211. This positioning part 34 ensures proper installation of the pusher 30, so that the groove 33 of the pusher 30 faces rearwards to mate with the connecting rod 45.

[0067] like Figure 5 and Figure 8As shown, the pushing member 30 includes a push rod 31 and a connecting block 32. The push rod 31 and the connecting block 32 are integral structures. The push rod 31 is at least partially located in the mounting cavity 21 and slides in cooperation with the second mounting groove 212 of the mounting cavity 21. The connecting block 32 is located in the movable cavity 13 and has a fourth limiting part 35, which is used to abut against the inner wall of the outer shell 10. The fourth limiting part 35 is disposed opposite to the first limiting part 22. In this embodiment, by acting on the connecting block 32, the push rod 31 moves within the mounting cavity 21, thereby realizing the blade replacement mechanism 210. The fourth limiting part 35 of the connecting block 32 abuts against the inner wall of the housing 10, preventing the push rod 31 from sliding out of the mounting cavity 21, and ensuring that at least one end of the push rod 31 abuts against the inner wall of the housing 10, thus improving the stability of the push rod 31 within the movable cavity 13. Furthermore, when the universal ball 201 moves, the fourth limiting part 35 also abuts against the inner wall of the housing 10, thereby limiting the rotation angle of the universal ball 201. Therefore, the fourth limiting part 35 has the function of limiting the universal ball 201 and limiting the push rod 31. Moreover, the connecting block 32 is also used to connect the stabilizer 40, improving the stability of the universal ball 201 during rotation.

[0068] like Figure 5 and Figure 6 As shown, the outer casing 10 has a first opening 11, a second opening 14, a movable cavity 13, and a third opening 17, which are sequentially connected. The first opening 11 is located at the front end of the outer casing 10, the second opening 14 and the third opening 17 are located at the rear end of the outer casing 10, the movable cavity 13 is located between the second opening 14 and the third opening 17, and the connecting block 32 is located inside the movable cavity 13. By pressing the connecting block 32 at the third opening 17 with a finger, the connecting block 32 moves within the mounting cavity 21 and pushes the cutting head mechanism 210 out of the outer casing 10. When the new cutting head mechanism 210 pushes the push rod 31, the push rod 31 drives the connecting block 32 to move within the movable cavity 13, allowing the connecting block 32 a certain amount of space to move within the outer casing 10 through the movable cavity 13, facilitating the replacement of the cutting head mechanism 210.

[0069] like Figure 5 As shown, the pushing mechanism also has a cover plate 50, which cooperates with the outer shell 10 and is located at the third opening. The inner side of the cover plate 50 abuts against the connecting block 32, and the outer side of the cover plate 50 has a pressing part 53. By sealing the third opening 17 with the cover plate 50, the connecting block 32 is hidden inside the outer shell 10, improving the aesthetics of the pushing mechanism. Moreover, the cover plate 50 has a pressing part 53, which, when applied, pushes the connecting block 32 to move.

[0070] like Figure 5 As shown, the outer casing 10 includes a first casing 101 and a second casing 102, with the second casing 102 mounted on the first casing 101. The first casing 101 has a first guide groove 104, and the second casing 102 has a second guide groove 105. The cover plate 50 has a first locking block 51 and a second locking block 52. The first locking block 51 engages with the first guide groove 104, and the second locking block 52 engages with the second guide groove 105. By engaging the first locking block 51 and the second locking block 52 with the first guide groove 104 and the second guide groove 105 respectively, when the push mechanism is used to replace the cutter head mechanism 210, the cover plate 50 is pushed to move, thereby causing the first locking block 51 to move within the first guide groove 104 and the second locking block 52 to move within the second guide groove 105, and moving the push rod 31 to a preset position, thereby ejecting the cutter head mechanism 210. After replacing the new cutter head mechanism 210, the mounting rod 230 pushes the push rod 31 to its original position. The push rod 31 then drives the cover plate 50 to reset via the connecting block 32. At this time, the first locking block 51 abuts against the first guide groove 104, and the second locking block 52 abuts against the second guide groove 105, thereby restricting the cover plate 50 at the third opening 17. This allows the cover plate 50 to both shield the connecting block 32 and the push rod 31 and facilitate the operation of the push rod 31 and the replacement of the cutter head mechanism 210. In this embodiment, the top of the first housing 101 has a limiting block 103, and the bottom of the second housing 102 has a limiting groove that cooperates with the limiting block 103.

[0071] Furthermore, in the absence of the first guide groove 104 and the second guide groove 105, the pressing part 53 has an arc-shaped groove, and at least a portion of the pressing part 53 is made of an elastic material. This elastic material allows the pressing part 53 to automatically reset after driving the connecting block 32, without needing to push the cover plate 50 to move within the housing 10.

[0072] Example 3

[0073] like Figures 10 to 14 As shown, the present invention also proposes a shaver 200, including a blade head mechanism 210, a handle 220, and a universal rotating mechanism 100 as described above. The universal rotating mechanism 100 is mounted on the handle 220, and at least a portion of the blade head mechanism 210 is mounted within the universal rotating mechanism 100. By mounting the blade head mechanism 210 within the universal rotating mechanism 100, when shaving with the shaver 200, the user can finely adjust the blade head mechanism 210 through the universal rotating mechanism 100 to bring the blade edge of the blade head mechanism 210 close to the contact surface and shave the beard. Moreover, after the blade head mechanism 210 swings in the first, second, and third directions, it is micro-operated by a stabilizer 40 and reset by the stabilizer 40 for the next use.
