[0034] The implementation and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0039] This utility model discloses a cutter head holder, as shown in Figures 1 to 7, including:

[0040] Base frame 1;

[0041] The frame 2 is detachably connected to the upper side of the base frame 1, and the frame 2 has a vertical through opening to form an installation port;

[0042] The active transmission frame 3 has its two ends fixedly connected to the two inner walls opposite to the mounting opening;

[0043] The passive transmission frame 4 is fixedly connected at both ends to the two inner walls opposite to the mounting opening, and the passive transmission frame 4 is parallel to the active transmission frame 3.

[0044] Two linkage components 5 are provided, both of which are detachably connected to the base frame 1. One linkage component 5 is detachably connected to one end of the active transmission frame 3 and one end of the passive transmission frame 4 at both ends, and the other linkage component 5 is detachably connected to the other end of the active transmission frame 3 and the other end of the passive transmission frame 4 at both ends, so that the active transmission frame 3 and the passive transmission frame 4 move in opposite directions.

[0045] By setting the frame 2, during assembly and disassembly, only the frame 2 needs to be installed on the base frame 1 to simultaneously install the active transmission frame 3 and the passive transmission frame 4, eliminating the need for separate assembly and disassembly of the active transmission frame 3 and the passive transmission frame 4, making assembly and disassembly simpler and faster. In this utility model, both linkage components 5 are located on the lower side of the active transmission frame 3 and the passive transmission frame 4. Specifically, when installing the frame 2, the two linkage components 5 are first detachably connected to the base frame 1, and then the frame 2 is installed, so that both linkage components 5 are simultaneously connected to the active transmission frame 3 and the passive transmission frame 4.

[0046] In practical use, the active transmission frame 3 is driven to swing back and forth. Under the transmission of the two linkages 5, the passive transmission frame 4 and the active transmission frame 3 are synchronously linked. During the horizontal reciprocating swing, the two form opposite movements to each other to reduce the vibration intensity. In this utility model, since the passive transmission frame 4 is subordinate to and synchronously linked with the active transmission frame 3, it is not connected to the drive motor itself. Therefore, the two ends of the passive transmission frame 4 will not twist.

[0047] Two linkages 5 are set between the active transmission frame 3 and the passive transmission frame 4, and the two linkages 5 are set separately. This can prevent the force transmission direction of the external drive motor from changing due to unexpected factors, which would cause the active transmission frame 3 and the passive transmission frame 4 to be unable to swing in parallel. This ensures that the active transmission frame 3 and the passive transmission frame 4 move in absolutely opposite parallel motion during operation. At the same time, it can also buffer the kinetic energy of multiple cutter heads driven by the active transmission frame 3 and the passive transmission frame 4, reduce the amplitude of multiple cutter heads, reduce the vibration intensity and temperature rise of the cutter heads, thereby achieving the purpose of reducing noise and improving user comfort.

[0048] It should be noted that, as a parallel solution, only one linkage 5 is set between the active drive frame 3 and the passive drive frame 4, which can also realize the reciprocating motion of multiple blades. However, when the force transmission direction of the drive motor changes (such as when the drive head is stuck with impurities or is damaged or missing, the force transmission direction of the drive head will also shift or tilt accordingly), the swing direction between the active drive frame 3 and the passive drive frame 4 may also shift or tilt. This will not only increase the fit clearance between the moving blade and the stationary blade, affecting the shaving performance of the blade, but also cause the local structure of the active drive frame 3 and the passive drive frame 4 to break due to uneven stress, reducing the service life of the blade.

[0049] Therefore, in the actual production and assembly process, as shown in the figure, there are two sets of linkage components 5, which are respectively installed at both ends of the passive transmission frame 4 and the active transmission frame 3. Compared with the traditional swing mechanism that uses one set of linkage components 5, setting two sets of linkage components 5 to make the passive transmission frame 4 and the active transmission frame 3 run synchronously in opposite directions can not only greatly offset the impact force of the unidirectional motion inertia of the passive transmission frame 4 and the active transmission frame 3 and reduce the vibration intensity of the swing mechanism, but also effectively improve the parallelism of the reciprocating swing at both ends of the passive transmission frame 4 and the active transmission frame 3, ensuring the shaving efficiency of the razor head.

[0050] Please refer to Figures 3 to 5. In the cutter head holder of this utility model, a frame groove 11 is provided on the upper side of the base frame 1, and the frame 2 is adapted and placed in the frame groove 11.

[0051] During installation, first, detachably connect the two linkage parts 5 to the base frame 1, then place the frame 2 on the base frame 1 so that the frame 2 enters the frame groove 11 of the base frame 1, thus completing the installation. The entire installation method is simple and quick. Moreover, the groove wall of the frame groove 11 can be used to limit the horizontal movement of the frame 2, ensuring the stability of the frame 2 during installation.

[0052] Please refer to Figures 1 to 4. The cutter head holder of this utility model also includes a top frame 6, which is detachably connected to the base frame 1 and pressed down on the side frame 2.

[0053] During installation, after placing the frame 2 on the base frame 1, the top frame 6 is then connected to the base frame 1. The top frame 6 presses the frame 2 stably down into the frame groove 11 of the base frame 1 to achieve stable installation of the frame 2 and reduce loosening of the frame 2 in the frame groove 11.

[0054] The tool holder of this utility model has a base frame 1 with multiple bottom fastening cylinders 13 fixedly connected to the upper side, a top frame 6 with multiple first fastening holes through it, and a top sleeve 61 with its upper end connected to each of the first fastening holes fixedly connected to the lower side of the top frame 6. Each top sleeve 61 is fitted onto the outside of each bottom fastening cylinder 13. The top frame 6 is connected to each bottom fastening cylinder 13 by multiple first fasteners passing through each of the first fastening holes.

[0055] When connecting the top frame 6 to the base frame 1, the top frame 6 is placed downwards on the base frame 1, and each top sleeve 61 is fitted onto the outside of each bottom fastening sleeve 13. The top sleeve 61 and the corresponding bottom fastening sleeve 13 form an interlocking effect to achieve stable installation of the top frame 6. After the top frame 6 is placed in place, each first fastener is placed in the corresponding first fastening hole and connected to the corresponding bottom fastening sleeve 13 to further ensure the stable installation of the top frame 6 under the action of each first fastener, and to ensure the stable installation of the frame 2 under the downward pressure of the top frame 6.

[0056] In this invention, each bottom fastening cylinder 13 has an internally threaded hole at its upper end, and each first fastener is a screw, so that a stable connection between the base frame 1 and the top frame 6 is achieved by connecting the screw to the corresponding bottom fastening cylinder 13 through screw threads. In addition, each first fastening hole is a countersunk hole, so that the head of the screw can enter into the top frame 6, ensuring the flatness of the upper side of the top frame 6.

[0057] Specifically, the number of bottom fastening sleeves 13 and top sleeves 61 can be two, three, four, or five, etc. The figure shows four, and they are all evenly distributed.

[0058] The blade holder of this utility model has multiple insertion holes 21 through the frame 2, and multiple insertion rods 62 are fixedly connected to the lower side of the top frame 6. Each insertion rod 62 is adapted to and inserted into each insertion hole 21.

[0059] When the top frame 6 is placed downwards on the base frame 1, and each top sleeve 61 is fitted onto the outside of each bottom fastening sleeve 13, each insertion rod 62 is adapted and inserted into each insertion hole 21. The connection between the frame 2 and the top frame 6 is stabilized by inserting the insertion rod 62 into the insertion hole 21. The limiting effect of each insertion rod 62 further ensures the stable installation of the frame 2.

[0060] Based on the above embodiment, a plurality of clearance holes 14 are provided on the base frame 1, and each clearance hole 14 is connected to each insertion hole 21 so that each insertion rod 62 is inserted into each clearance hole 14, and the clearance hole 1 is used to avoid the insertion rod 62.

[0061] Specifically, the number of inserts 62 can be two, three, four, or five, etc. The figure shows four, all of which are evenly distributed.

[0062] Please refer to Figures 3 and 4. The cutter head holder of this utility model also includes a flexible sealing plate 7 located between the base frame 1 and the top frame 6. The top frame 6 is pressed down on the frame 2 by the flexible sealing plate 7, and the flexible sealing plate 7 has multiple through holes 71, through which each insertion rod 62 passes.

[0063] After placing the frame 2 on the base frame 1, and before placing the top frame 6 downwards on the base frame 1, the flexible sealing plate 7 is placed on the base frame 1. At this time, the flexible sealing plate 7 seals the frame groove 11 of the base frame 1, and the frame 2 is located on the lower side of the flexible sealing plate 7. Then, the top frame 6 is placed downwards on the base frame 1. During this process, each insert rod 62 passes through each through hole 71 and is inserted into each insert hole 21 to position and install the flexible sealing plate 7 through each insert rod 62, ensuring that the flexible sealing plate 7 will not be displaced.

[0064] The flexible sealing plate 7 can be made of rubber material.

[0065] Based on the above embodiments, a lower sealing ring 72 is fixedly connected to the lower side of the flexible sealing plate 7, and a corresponding position of the base frame 1 is provided for the lower sealing ring 72 to enter the lower sealing groove. This improves the sealing strength between the flexible sealing plate 7 and the base frame 1 by allowing the lower sealing ring 72 to enter the lower sealing groove. At the same time, the lower sealing groove can be used to limit the placement of the flexible sealing plate 7 on the base frame 1, thereby enabling the rapid installation of the flexible sealing plate 7.

[0066] An upper sealing ring 73 is fixedly connected to the upper side of the flexible sealing plate 7, and a corresponding opening is provided on the top frame 6 for the lower upper sealing ring 73 to enter the upper sealing groove. This improves the sealing strength between the flexible sealing plate 7 and the top frame 6 by allowing the upper sealing ring 73 to enter the upper sealing groove.

[0067] Please refer to Figures 4 and 5. In the cutter head holder of this utility model, the base frame 1 is fixed with two vertically arranged hinge shafts 12; the active transmission frame 3 has two first linkage slots 311 through it, and the passive transmission frame 4 has two second linkage slots 411 through it; both linkage components 5 include a bridging plate 51 and two vertically arranged linkage shafts 52 with their lower ends fixedly connected to both ends of the bridging plate 51. The middle of the two bridging plates 51 has a through opening to form a hinge hole 511. The two hinge shafts 12 are respectively adapted to and inserted into the two hinge holes 511. The upper ends of the two linkage shafts 52 of one linkage component 5 are respectively inserted into one of the first linkage slots 311 and one of the second linkage slots 411, and the upper ends of the two linkage shafts 52 of the other linkage component 5 are respectively inserted into the other first linkage slot 311 and the other second linkage slot 411.

[0068] When the two linkage components 5 are connected to the base frame 1, the two hinge shafts 12 pass through the hinge holes 511 of the two linkage components 5 respectively, so as to ensure the working stability of the linkage components 5 during the reciprocating swing of the active transmission frame 3 and the passive transmission frame 4, and to ensure the shaving efficiency of the shaver; then the frame 2 is placed on the base frame 1, so that the four linkage shafts 52 pass through the corresponding first linkage groove 311 and second linkage groove 411 respectively, so as to realize the quick installation of the linkage components 5.

[0069] In this technical solution, the linkage shafts 52 of the linkage component 5 are respectively inserted into the first linkage groove 311 of the active transmission frame 3 and the second linkage groove 411 of the passive transmission frame 4. The bridge plate 51 is hinged and fixed to the hinge shaft 12 set in the middle of the base frame 1. When the active transmission frame 3 swings horizontally under the power of the drive motor, it can synchronously drive the passive transmission frame 4 to swing horizontally in the opposite direction, thereby achieving kinetic energy buffering of multiple blades, reducing the amplitude of the blades, and reducing the vibration intensity of the blades. The side walls of the four linkage shafts 52 respectively abut against the inner walls of the first linkage groove 311 and the second linkage groove 411 to ensure the absolute parallel interval between the active transmission frame 3 and the passive transmission frame 4 during the horizontal reciprocating swing process, avoiding mutual friction between the active transmission frame 3 and the passive transmission frame 4 to generate resistance, which would affect the shaving performance of the blades and increase the temperature rise of the blades, thus reducing the comfort of using the blades. The first linkage groove 311 and the second linkage groove 411 are both strip-shaped grooves with equal lengths. The lengths of the first linkage groove 311 and the second linkage groove 411 are set to be equal to the swing strokes of the active transmission frame 3 and the passive transmission frame 4 to avoid excessive swinging of the active transmission frame 3 and the passive transmission frame 4, which could damage the moving and stationary blades of the cutter head. The linkage shaft 52 has a truncated cone-shaped structure to facilitate assembly.

[0070] Please refer to Figures 6 and 7. The cutter head holder of this utility model includes an active transmission frame 3, which comprises an active frame body 31, two active springs 32, an active transmission part 33 fixedly connected to the upper side of the middle of the active frame body 31, and a swing frame 34 fixedly connected to the lower side of the middle of the active frame body 31. One end of each of the two active springs 32 is fixedly connected to both ends of the active frame body 31, and the other end is fixedly connected to the two inner walls opposite to the mounting opening. The upper end of the active transmission part 33 is provided with at least one active transmission hole. One end of each of the two linkages 5 is detachably connected to both ends of the active frame body 31.

[0071] The swing bracket 34 is used for transmission connection with the output end of the drive motor, and the active transmission hole is used for transmission and mounting of the shaving head. Specifically, there can be one, two, or three active transmission holes, etc. The figure shows two holes to achieve transmission connection with two shaving heads simultaneously. The first linkage groove 311 is formed in the active bracket body 31. Both active springs 32 are U-shaped structures, made of thin U-shaped sheets, which serve to fix the active bracket body 31. At the same time, they also facilitate the horizontal reciprocating swing of the active bracket body 31 under the action of external force to realize the shaving operation of the shaving head.

[0072] By setting active springs 32 at both ends of the active frame body 31, when the swing frame 34 is driven by the drive motor to swing the active frame body 31 horizontally back and forth, it can not only reduce the resistance of the active transmission frame 3 during the horizontal back and forth swing, ensuring the horizontal swing performance of the active transmission frame 3 and reducing the working current, thus extending the battery life, but also facilitate the rapid reset of the active transmission frame 3.

[0073] The cutter head holder of this utility model includes a passive transmission frame 4 comprising a passive frame body 41, two passive spring pieces 42, and a passive transmission part 43 fixedly connected to the upper side of the middle end of the passive frame body 41. One end of each of the two passive spring pieces 42 is fixedly connected to both ends of the passive frame body 41, and the other end is fixedly connected to the two inner walls opposite to the mounting opening. The upper end of the passive transmission part 43 is provided with at least one passive transmission hole, and the other ends of the two linkage members 5 are detachably connected to both ends of the passive frame body 41.

[0074] The passive drive hole is used for driving and mounting the razor head. Specifically, there can be one, two, or three passive drive holes; the figure shows one hole to achieve the drive connection of the razor head. The second linkage groove 411 is formed in the passive frame body 41. Both passive spring pieces 42 are U-shaped, composed of thin U-shaped sheets, serving to fix the passive frame body 41. Simultaneously, they facilitate the horizontal reciprocating swing of the passive frame body 41 under external force, enabling the razor head to perform shaving operations.

[0075] Since the passive transmission frame 4 is subordinate to and synchronously linked with the active transmission frame 3, and is not connected to the drive mechanism itself, the two ends of the passive transmission frame 4 will not twist.

[0076] Since there are various styles of shavers, they are mainly distinguished by the number of blades, such as three-blade shavers, four-blade shavers, or even more blades. Specifically, when there are two drive ports, two blades can be installed simultaneously.

[0077] Based on the above embodiment, the top frame 6 has a through opening in the middle to allow the active transmission part 33 and the passive transmission part 43 to pass through. Two sealing sleeves 74 are fixedly connected to the flexible sealing plate 7, and the two sealing sleeves 74 are respectively fitted onto the active transmission part 33 and the passive transmission part 43 to achieve a seal.

[0078] This utility model also discloses a shaver, as shown in Figures 8 to 11. It includes the aforementioned shaver head holder, as well as a lower housing 8 and an upper housing 9. A drive motor 81 is installed inside the lower housing 8. The output end of the drive motor 81 is connected to the swing frame 34 of the active transmission frame 3 through an eccentric transmission component. The upper housing 9 is snapped into the upper opening of the lower housing 8, and a plurality of shaver heads 91 are provided inside the upper housing 9. Each shaver head 91 is respectively driven and installed in the active transmission hole of the active transmission part 33 of the active transmission frame 3 and the passive transmission hole of the passive transmission part 43 of the passive transmission frame 4.

[0079] The output shaft of the drive motor 81 is fixed to the transmission wheel of the eccentric transmission component. The eccentric shaft of the eccentric transmission component is inserted into the swing frame 34 of the active transmission frame 3. When the drive motor 81 drives the eccentric transmission component to rotate, the eccentric shaft of the eccentric transmission component repeatedly rotates and impacts the two side walls of the swing frame 34, causing the active transmission frame 3 to swing back and forth. When the eccentric shaft rotates and impacts the two side walls of the swing frame 34, it not only applies a lateral thrust to the side walls of the swing frame 34, causing the active transmission frame 3 to swing back and forth, but also applies a radial thrust to the side walls of the swing frame 34 in the direction of rotation. This causes the two ends of the active transmission frame 3 to twist repeatedly, greatly increasing the working vibration intensity of the shaver and reducing the comfort of using the shaver. To improve the torsional resistance of the active transmission frame 3 and minimize the torsional amplitude at both ends of the active transmission frame 3 during horizontal reciprocating swing, the active transmission frame 3 is provided with two active springs 32, and the passive transmission frame 4 is provided with two passive springs 42. By setting active spring 32 and passive spring 42 on the active transmission frame 3 and passive transmission frame 4 respectively, when the active transmission frame 3 and passive transmission frame 4 are fixed in the lower housing 8 and the active transmission frame 3 is driven by the drive motor 81 to swing horizontally back and forth, the resistance during the horizontal swinging process of the active transmission frame 3 and passive transmission frame 4 can be reduced, ensuring the horizontal swinging performance of the active transmission frame 3 and passive transmission frame 4 and reducing the operating current, thus extending the battery life. At the same time, it also facilitates the rapid reset of the active transmission frame 3 and passive transmission frame 4. Secondly, since the passive transmission frame 4 is subordinate to and synchronously linked with the active transmission frame 3, and is not connected to the drive motor 81 itself, the two ends of the passive transmission frame 4 will not twist.

[0080] The base frame 1 is mounted on the lower housing 8. Specifically, multiple support plates 82 are fixedly connected to the inner wall of the lower housing 8 to provide stable support for the base frame 1. Furthermore, multiple support columns 83 are fixedly connected to the inner wall of the lower housing 8. The support columns 83 are vertically oriented and have internal threaded holes at their upper ends. Multiple second fastening holes are drilled through the corresponding positions of the base frame 1.
