Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, and in particular to an eyebrow trimmer and its eyebrow trimming method. Background Technology

[0002] An eyebrow trimmer is a beauty tool, usually made of high-quality plastic and blades. It can be used to manually shape, outline, and shape eyebrows, making the face look more refreshed and beautiful.

[0003] Existing eyebrow trimmers have limited functionality, only capable of simple removal of hair. They cannot be comfortably held by different users at different angles, allowing for free adjustment of the trimming angle. Multiple tools are required to complete eyebrow trimming, which is inconvenient and prevents the simultaneous and convenient achievement of the best eyebrow trimming angle, thus failing to better meet user needs. Therefore, we have proposed an eyebrow trimmer.

[0004] Secondly, current eyebrow trimmers mainly feature folding or integrated blades. However, the brow bone in the face is not a flat structure. Existing eyebrow trimmers typically have a flat, elongated blade and a rigid handle. This requires precise control over the angle and direction of force applied during the trimming process. For inexperienced users, an excessively long blade can lead to inconsistent blade strength due to variations in the length of the brow (head, arch, and tail), resulting in errors when applying insufficient force. While some technologies address this by reducing the blade length, different trimming areas require different blade lengths. Simply increasing or decreasing the blade length alone does not effectively solve the problem.

[0005] Thirdly, some existing technologies use electric designs for eyebrow trimming. In reality, to maintain safety and stability, the blade head of these eyebrow trimmers cannot be designed to be too long, and the blade head is usually enclosed under a protective mesh. In actual operation, it is also very difficult to adapt to the curved design of the eyebrow trimming angle. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an eyebrow trimmer and its trimming method. By using a connecting seat between the trimmer's body and handle, a flexible and adjustable connection is achieved, unlike the traditional rigid connection between the body and handle. The trimmer body can rotate at an angle with the support of the connecting seat, granting it freedom of rotation and / or tilting for multiple working states and functions. This allows for flexible adjustment when the trimmer head interacts with the eyebrow's multiple curved segments. During operation, different tilt angles and trimmer rotations can be adjusted according to the direction and length of the eyebrow segment and the force applied during trimming. Firstly, this facilitates different contact lengths and contact areas when contacting the eyebrow segment, allowing the user to quickly grasp the appropriate trimming angle. Secondly, the overall design of the trimmer's grip is improved, incorporating an ergonomic grip structure and positioning area, which, combined with the trimmer head design, results in a rationally designed structure and allows for quick and comfortable handling.

[0007] This invention discloses an eyebrow trimmer, comprising a handle and a blade, characterized in that the handle and the blade are connected by a connecting seat;

[0008] The connecting seat is configured to have a rotating component at either the connection end with the handle or the connection end with the blade body. The rotating component is rotatable about the axial direction at a first position in the axial direction of the eyebrow trimmer, thereby rotating the blade body. The rotating component includes:

[0009] A connecting shaft, with its first end connected to the tool holder or the tool body, and its second end connected to a rotating base;

[0010] A fitting block is disposed between the first end and the second end of the connecting shaft to achieve angular limiting after the blade body rotates;

[0011] A limiting block is used to engage with the fitting block to achieve angular limiting;

[0012] The angle limit includes a first limit, which is a limit on the angle of rotation of the blade body along the axial direction.

[0013] According to the present invention, the eyebrow trimmer proposes a flexible and adjustable structure between the handle and the blade body. The rotating base can cooperate with a mounting base to achieve rotation. The mounting base is located at the end of the handle, the end of the blade body, or as an integral part of the connecting base. The connecting shaft in the connecting base cooperates with the rotating base to achieve rotation. This cooperation method allows the rotating base to be disc-shaped or spherical, with a corresponding disc-shaped or spherical receiving groove in the mounting base, enabling rotation in multiple dimensions and angles.

[0014] The main way the interlocking block and the limiting block cooperate is by interlocking. The interlocking method can be that the thickness of the two blocks is exactly the same in the axial direction or that the thicknesses are different. The interlocking can be a complete interlocking or a partial interlocking.

[0015] Ultimately, the state of the interlocking block and the limiting block enables the positioning or limiting of the rotation angle between the rotated tool body and the tool holder.

[0016] Furthermore,

[0017] Includes a first groove for accommodating the rotating base, the first groove being located at a first position in the axial direction; at the first position, the fitting block and the limiting block are fitted and fixed, and the first limit of the angle limiting is maintained; the first groove is disposed within the connecting seat or within the handle structure or the blade body structure;

[0018] At this time, the eyebrow razor adjusts its angle as the connecting seat rotates.

[0019] or,

[0020] The system includes a first groove for accommodating the rotating base, the rotating base rotating within the first groove, the first groove being located at a first position in the axial direction; at the first position, the fitting block and the limiting block form a fitting gap, the connecting shaft moving within the fitting gap, and a second limiting position for angular limiting being maintained, the second limiting position being such that the blade body maintains an inclined angle with the blade body under the limitation of the fitting gap distance between the fitting block and the limiting block, the first groove being disposed within the connecting base or within the handle structure or the blade body structure.

[0021] At this time, the connecting shaft has a certain swing space, and the limiting block can be set at the end of the tool holder section or the end of the tool body section.

[0022] Furthermore,

[0023] The system includes a second groove for accommodating the rotating base, the rotating base rotating within the second groove, and the second groove being located at a second position in the axial direction. At the second position, the fitting block and the limiting block form a fitting misalignment, the first limit of the angle limit is released, and the rotation of the rotating base drives the angle limit adjustment. The second groove is disposed within the connecting seat or within the handle structure or the blade body structure.

[0024] or,

[0025] The connecting seat further includes a second groove for accommodating the rotating base, the rotating base rotating within the second groove, the second groove being located at a second position in the axial direction; at the second position, the fitting block and the limiting block form a fitting gap, the connecting shaft moves within the fitting gap, the second limit of the angle limit is maintained, the second limit is such that the blade body maintains an inclined angle with the blade body under the limitation of the fitting gap distance between the fitting block and the limiting block, the second groove being disposed within the connecting seat or within the handle structure or the blade body structure.

[0026] When the eyebrow razor has a second angle limit, the fitting gap distance can be incomplete contact. The fitting gap distance is supplemented by another fitting block that passes through and connects the shaft, so as to better fix the tilt angle and release the flexible state.

[0027] Furthermore,

[0028] The outer peripheral surface of the interlocking block is provided with multiple protrusions of the same or different shapes, each protrusion indicating at least one unit rotation angle. Correspondingly, the inner peripheral surface of the limiting block is provided with multiple grooves, and the protrusions and grooves correspond to form an angular limiting.

[0029] Furthermore,

[0030] A groove channel is provided between the first groove and the second groove, and the rotating base changes position between the first groove and the second groove through the groove channel;

[0031] The diameter of the groove channel is smaller than the diameter of the rotating base, so that the rotating base maintains its position between the first groove and the second groove. The groove channel is flexibly designed so that the rotating base can pass through when its position changes.

[0032] Furthermore,

[0033] The protruding structure is a gear structure, and the tips of the gear teeth are arc-shaped. Correspondingly, the surface of the groove on the inner circumference of the limiting block is also arc-shaped.

[0034] The arc-shaped fitting surface protects the structure of the eyebrow razor during operation, ensuring its lifespan.

[0035] Furthermore,

[0036] The handle has a first grip section and a second grip section, which are fixedly or movably connected. The first grip section has a thumb-and-finger resting part, and the second grip section has at least one positioning groove corresponding to the fingertip for finger gripping.

[0037] Furthermore,

[0038] The tiger's mouth resting part has a first type of concave structure, and the positioning groove has a second type of concave structure. The first type of concave structure acts on the hand, and the second type of concave structure acts on the fingertip. In the axial direction, the length of the first type of concave structure is more than three times the length of the second type of concave structure.

[0039] Furthermore,

[0040] The fitting gap distance is the radial fitting distance between the limiting block and the fitting block. Under different limiting angles, the fitting distance may be the same or different.

[0041] This invention also provides a method for shaping eyebrows, using the aforementioned eyebrow trimmer.

[0042] The eyebrow shaping method includes the following steps:

[0043] S1: The eyebrow trimming operation of the first function is completed by holding the positioning groove of the second handle section. In the state of the first function, the angle limit of the connecting shaft in the connecting seat is maintained at the first angle, and the parallel direction of the blade head provided on the blade body is kept parallel to the tiger's mouth support section.

[0044] S2: By holding the blade, rotating the connecting seat, or pulling or pressing the connecting seat, adjusting its position in the axial length direction, and then performing the rotation operation, and then pressing or pulling in the opposite direction, the second function of eyebrow trimming is completed. The blade and the tiger's mouth support section are not parallel to each other, but are offset by a certain angle limit.

[0045] Furthermore,

[0046] It also includes step S3:

[0047] S3: By holding the blade, push the connecting seat, adjust the engagement position of the limiting block and the fitting block, and complete the eyebrow trimming operation of the third function. The blade and the tiger's mouth support section are not parallel and have a certain angle limit. The angle limit is that there is a certain relative tilt angle between the blade and the handle.

[0048] The beneficial effects of the eyebrow trimmer implemented according to the invention are:

[0049] This invention proposes an eyebrow trimmer with a flexible adjustment connecting seat between the handle and the blade. The connecting seat does not restrict the blade in a fixed manner. The blade and the connecting seat together, or the blade relative to the connecting seat, are adjustable, so that the blade can be angularly limited relative to the handle in at least one dimension.

[0050] This invention improves the flexibility of the razor by incorporating a rotating component in the connecting seat, the grip section of the handle, or the connecting part of the blade, thereby granting the blade freedom of rotation. This allows for a more comfortable grip and enhances the user's handling experience. Users can also customize the angle between the handle and the blade to best suit their individual needs during eyebrow shaping.

[0051] The present invention further improves upon the eyebrow razor by using an angle-limiting fitting method in the connection of the connecting seat, which allows the relative tilt angle between the blade body and the handle to be adjusted through the fitting gap. This enables the angle limitation of the eyebrow razor to act on the relative angle between the blade body and the handle, thus limiting the eyebrow angle from a second dimension.

[0052] The eyebrow trimmer of this invention features a handle designed with a fingertip grip section and a hand-support grip section. The fingertip grip section incorporates multiple positioning parts designed to act on the fingertips. The different structural designs on the outer periphery of these grip sections, along with their interplay, allow users to quickly achieve a comfortable grip posture for easy operation. This ergonomic design enables users to quickly and accurately find the appropriate grip position for eyebrow trimming, resulting in better grip and directional adjustment, and allowing for the indication of various eyebrow trimming angles.

Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0062] This invention provides an eyebrow trimmer, which includes a handle and a blade. The handle has a curved design to provide multiple handheld positions during eyebrow trimming to assist in controlling the force applied when shaving the eyebrows.

[0063] The connecting seat is located between the handle and the blade body to keep the blade body in a certain position. The force for shaving eyebrows is transmitted to the blade body through the connecting seat by the position of the handle.

[0064] The connecting seat is also used to adjust the radial rotation of the blade in the axial direction and the tilt of the blade relative to the handle. In this way, the contact length and force between the blade and the eyebrow skin can be adjusted to achieve a better eyebrow shaving effect.

[0065] The connecting seat has a connecting shaft with a first end and a second end. The first end is fixedly connected to the cutting head, and the second end is flexibly connected to the tool holder. In one specific embodiment, the flexible connection is made of an elastic material, a spring, or a universal joint. The first end is spherical and fits into a spherical hole in the tool holder. The connecting shaft can rotate within the spherical hole and can form a certain tilt angle, allowing the cutting head and the connecting shaft to tilt together relative to the tool holder. In one specific embodiment, the first end is flexibly connected to the cutting head, and the second end is fixedly connected to the tool holder, allowing the cutting head to rotate and tilt relative to the connecting shaft. In this way, the connecting seat achieves stepless rotational adjustment.

[0066] The blade body includes a blade holder on which at least one blade of a certain length is mounted, the blade contacting different positions of the eyebrow shape to perform eyebrow shaving.

[0067] The handle comprises two connected sections: a grip section and a hand rest section. The grip section has a first axial length, and the hand rest section has a second axial length.

[0068] The grip section has at least one concave structure in the circumferential direction. This concave structure has a certain curvature and points in the opposite direction to the central axis of the grip section. Preferably, multiple concave structures are distributed in the circumferential direction, such as two or three. The surface shapes of the concave structures can be the same or different, meaning the curvature distribution of each concave structure can be the same or different. In this way, multiple grip positioning indicators can be provided. For example, two symmetrically distributed positions indicate the operating angle of the blade, or three are distributed circumferentially at an average interval to provide multiple grip angles and grip force indicators in the circumferential direction.

[0069] The hand rest section is a curved rod of a certain length. The curvature of the curved rod forms a fixed angle with the grip direction of the holding section. For example, in three circumferential grip modes, with two curved grip angles, the curvature of the hand rest section rests against the hand to provide a more stable grip during eyebrow shaping. As an improvement, the curved rod is designed with an adjustable curvature made of flexible material. This allows for flexible adjustment of the curvature direction and positioning, thus providing adjustable hand rest positions in multiple curvature directions.

[0070] The blade holder has a first side body and a second side body, which are symmetrical in shape. A blade of a certain length is clamped between the two side bodies, and the blade can be disassembled and replaced.

[0071] The outer surfaces of the first and second side bodies also have a curved design, with a first thickness near the handle and a second thickness away from the handle, wherein the first thickness is greater than the second thickness. With this configuration, the surfaces of the first and second side bodies also have a concave structure with varying curvature, so that the fingertip can also operate the blade on the outer surfaces of the first and second side bodies. When the blade head is flexibly installed, it can be operated according to the user's ergonomic characteristics.

[0072] A limiting block is provided at the top of the tool holder. The radial length of the limiting block is slightly smaller than the radial length of the tool holder. In one embodiment, the limiting block is embedded in the top of the tool holder. A hole is provided on the limiting block. A fitting block that basically matches the shape of the hole is matched with the connecting shaft. Under the movement of the connecting shaft, the fitting block adjusts its position. The adjustable position includes a 360° rotation on a plane, or a swinging motion that occurs with the swinging motion of the connecting shaft, or a tilting state that occurs with the tilting adjustment of the elastic position of the connecting shaft.

[0073] The side edge of the interlocking block has a matching shape that matches the groove of the limiting block. As the interlocking block is adjusted with the connecting shaft, a corresponding matching shape is formed between the two, so that the position of the blade on the connecting seat can be fixed by the limiting operation to achieve the eyebrow trimming position.

[0074] The operation of the above structure can also be set between the connecting seat and the blade head. Essentially, it can maintain the fixation of the current eyebrow trimming operation in a restricted position during the movement of the connecting shaft.

[0075] In this way, the blade head can rotate freely, allowing for better eyebrow shaping by adjusting the blade, grip, and support sections according to the user's operation. The free adjustment of the blade head relative to the handle allows for better adaptation to different heights and curves of the brow bone.

[0076] As a further improvement of the present invention, the thickness parameter of the interlocking block in the axial direction is greater than the depth parameter of the limiting block, so as to achieve a greater distance of interlocking between the interlocking block and the limiting block and a more stable position fixation.

[0077] As a further improvement of the present invention, the matching shape of the interlocking block on the side edge is evenly distributed circumferentially, and there is no limiting distance between the interlocking contact between the matching shape of the interlocking block and the limiting block. Thus, the axial position of the connecting shaft is operated so that the height of the axial position of the interlocking block is higher than the height of the limiting block. Thus, the rotation of the interlocking block is unrestricted. After the user rotates the cutter head and operates the rotation of the cutter head, the state of no limiting distance between the interlocking block and the limiting block is pushed back.

[0078] As a further improvement of the present invention, the matching shape of the interlocking block on the side edge is distributed circumferentially uniformly or non-uniformly. In one specific embodiment, at one-third of the 360° circumferential arc segment, the interlocking contact between the matching shape of the interlocking block and the limiting block has a first limiting distance; at two-thirds of the 360° circumferential arc segment, there is a second limiting distance; and at the other one-third of the arc segment, there is a third limiting distance. This allows the auxiliary connecting shaft to generate different tilt angles between the cutter head and the cutter shank at different rotation angles. Different limiting distances enable the connecting shaft to generate different limiting strokes at different limiting distances during rotation, thereby achieving different tilt angles.

[0079] During eyebrow shaping, the entire eyebrow section actually consists of multiple segments related to the facial bones, such as the inner brow, middle brow, and outer brow. Among these, the upper part of the inner and middle brow sections, near the forehead, has relatively smooth bone structure, allowing for a longer contact length between the blade and the brow bone. However, near the eyes in the inner brow section, where it connects to the bridge of the nose, the facial indentation is deeper. Therefore, the contact length between the blade and the brow bone needs to be shorter during eyebrow shaping. In this case, a fixed eyebrow blade cannot be adjusted in relative position; the user needs to change the operating angle and find the most suitable contact position for the blade head. Adjusting the handle position allows the eyebrow blade to operate at the appropriate angle, but this is actually very inconvenient. An adjustable blade head and handle position means that the contact position of the blade and the relative position between the blade and the handle can be adjusted, which reduces the skill required of the operator.

[0080] In one preferred embodiment of the present invention, the matching shape of the fitting block on the side edge is distributed in a gear shape, and the shape of the hole opened by the corresponding limiting block is also gear-shaped. The gear-shaped structure has multiple gear structures. In this way, more rotation angles can be indicated to the user, such as 15° to 20° as the adjustment unit to perform the rotation adjustment level.

[0081] In a preferred embodiment of the present invention, the outermost edge of the gear is rounded, and thus the hole of the limiting block is also rounded. This not only avoids sharp contact wear, but also allows for further rotational fine-tuning space after the two are locked in place.

[0082] like Figure 1-6 As shown in the figure, the present invention discloses an eyebrow trimmer, including a handle 1 and a blade body 2. The handle 1 and the blade body 2 are connected by a gear device 3. The gear device 3 includes a mounting boss 31 with a gear-shaped groove at one end of the handle near the blade body, a gear 32, and a rotating shaft 33 coupled to the gear at one end of the blade body 2 near the handle 1. The mounting boss has a mounting groove 23.

[0083] like Figure 1-5 As shown in the figure, the present invention discloses an eyebrow trimmer, including a handle 1 and a blade body 2. The handle 1 and the blade body 2 are connected by a gear device 3. The gear device 3 includes a mounting boss 31 with a gear-shaped groove at one end of the handle near the blade body, a gear 32, and a rotating shaft 33 coupled to the gear at one end of the blade body 2 near the handle 1. The mounting boss has a mounting groove 23.

[0084] Among them, the gear device enables the blade to rotate freely 360°, breaking through the limitations of the traditional eyebrow trimmer's angle of use. Users can customize the most suitable angle according to their own needs. Furthermore, by setting a single axis that can rotate 15°, users can keep the blade in different hand positions and at different angles during use, making it convenient and quick to adjust the blade to the best trimming angle for the eyebrows.

[0085] Especially Figure 6 As shown, in one embodiment of the present invention, a first position has a universal groove seat that matches one end of the connecting shaft. The connecting shaft is matched with the universal groove seat to realize the rotation or swing rotation of the connecting shaft. In the second position after the connecting shaft is pressed, the limiting block and the fitting block cooperate to fix the rotation position at this time, or there is a certain space between the limiting block and the fitting block in the radial direction, and there may also be a certain displacement distance between the two.

[0086] Specifically, such as Figure 6 As shown, in the first position, the connecting shaft 33 is closer to the lower end of the blade body. At this time, the limiting block 31 and the fitting block 32 are in a mutually fitted state. At this time, the first universal groove seat 131 set in the first position can cooperate with one end of the connecting shaft 131 to achieve rotation. Other rotating base structures can achieve rotation operations at corresponding positions. When the limiting block 31 and the fitting block 32 have different fitting gaps, a tilting angle state can be achieved. The tilting angle is the relative angle between the blade body and the handle.

[0087] In another embodiment, in the first position, the connecting shaft 33 is closer to the lower end of the blade body. At this time, the limiting block 31 and the fitting block 32 are in a mutually fitted state and are in a completely fixed relative state. The connecting shaft 33 is pulled up to the second position through the universal seat groove 132. At this time, the limiting block 31 and the fitting block 32 are disengaged from the mutually fitted state. At this time, the connecting shaft 33 can rotate in the second groove seat 133.

[0088] The first universal groove seat 131, the universal seat through groove 132, and the second universal groove seat 133 are disposed inside the structure of the grip positioning part 13, or as one of the seats of the connecting seat, and are disposed between the blade body 2 and the handle 1.

[0089] The elastic connector provided according to the present invention is disposed between the limiting block 32 and the gripping positioning part 13, or is a part of the connecting shaft 33. Specifically, it is a spring with a fixing function, or a flexible material that can be compressed and held and then rebound, or it is disposed between the upper end of the connecting shaft 33 and the gear 32, or between the lower end of the connecting shaft 33 and the gear 32.

[0090] Among them, the blade body is given 360° free rotation by gears, breaking through the usage angle limitations of traditional eyebrow trimmers. Users can customize the most suitable angle according to their own needs. Furthermore, by setting a single axis that can rotate 15°, users can keep the blade body in different hand positions and at different angles during use, making it convenient and quick to adjust the blade body and the best trimming angle for eyebrows.

[0091] The handle 1 can be configured as a combination of a first grip section and a second grip section, or it can be configured as a one-piece molded handle design with a certain tilt angle and streamlined shape.

[0092] The handle 1 has a first type of curved surface structure at the end away from the blade 2, and further includes a grip section and a thumb-and-tiger mouth section, so that users can more conveniently perform eyebrow trimming operations by pinching and / or placing it in the thumb-and-tiger mouth according to their own needs and usage habits.

[0093] In a preferred embodiment of the present invention, the handle has a polyhedral circumferential surface at one end near the blade body. At least one grip positioning part is provided on the polyhedral circumferential surface for indicating a first grip position. This part is a first type of concave structure for indicating the hand position during eyebrow trimming, used for quick positioning, and has the function of indicating the grip position of the eyebrow trimmer. The length of the concave structure is less than the length of the handle end body.

[0094] The first type of concave structure mentioned above, in the above component settings, is a concave inward of the surface towards the axis relative to the overall shape and structure of the eyebrow trimmer when in use, so that the eyebrow trimming grip positioning area can be indicated. The first type of concave structure can indicate different eyebrow trimming grip positioning positions. The grip position is located on the first type of concave structure of the handle, indicating different eyebrow trimming grip types and positions, such as different positions such as the root of the eyebrow, the brow bone, etc.

[0095] The preferred concave structure is a trihedral concave structure.

[0096] By designing different areas of the handle, such as the grip section away from the blade, in addition to assisting the stability of the handle in contact with the plane, the position and shape of the first type of concave structure can further assist in the indication of eyebrow trimming operations, making the product adaptable to the needs of eyebrow trimming operations at different levels and angles.

[0097] The blade body in this invention can be configured as having a blade 21 and a blade holder 22 for mounting the blade, or it can be configured as a one-piece molded blade that can be directly connected to a rotating shaft. Furthermore, the blade holder has a second type of concave structure, a second type of curvature, and a second type of length, making the eyebrow trimmer more streamlined and improving the grip and user experience.

[0098] According to the present invention, the length of the abutment section of the razor handle ranges from 60mm to 90mm, the length of the grip section ranges from 20mm to 30mm, the length of the razor tip section ranges from 10mm to 33mm, and the length of the connecting seat ranges from 2mm to 10mm. The axial length of the limiting block is 0.5mm to 1mm, and the exposed connecting shaft of the connecting seat is 1mm to 5mm long.

[0099] Specifically, the present invention discloses an eyebrow trimmer, including a handle and a blade, wherein the handle and the blade are connected by a gear device;

[0100] The gear mechanism includes a mounting boss with a gear-shaped groove at one end of the handle near the blade body, a gear, and a rotating shaft coupled to the gear at one end of the blade body near the handle. The handle has a polyhedral circumferential surface, and at least one grip positioning part for indicating a first grip position is provided on the polyhedral circumferential surface, which is a first type of concave structure for indicating the hand position during eyebrow trimming. The gear structure has a periodic gear structure on its peripheral side. The period refers to the tooth angle of the gear. Each tooth angle is a period. One or more tooth angles correspond to a certain rotation angle. Thus, the rotation angle may include multiple tooth angles. The structure of each tooth angle may be the same or different. In this way, the radial engagement distance of the circumferential surface is the same or different. When the periodic structure of the circumferential surface is uniform and the same, the distance between the gear 32 and the limiting block 31 can be an engagement or a certain gap distance between the two. The connecting shaft drives the gear 32 to have a certain displacement distance in the gap distance. At this time, a certain angle may be generated between the blade body and the blade holder. The relative angle between the two can have different degrees of tilt depending on the engagement distance. While adjusting the operating angle, a certain degree of buffer is left for the eyebrow trimming operation.

[0101] The knife handle has a first grip section and a second grip section, which are fixedly or movably connected.

[0102] The first grip section has a first type of curved surface structure. The first curved surface structure includes a grip section near the blade end and a thumb-and-shoulder section away from the blade end. The first type of concave surface structure includes a first type of curvature and a first type of length. The first type of concave surface structure is preferably a trihedral concave surface structure.

[0103] The blade body includes a blade and a blade holder for mounting the blade. The blade holder has a second type of concave structure. The second type of concave structure has a second type of curvature and a second type of length. The blade has a shearing head with a beveled edge.

[0104] Furthermore, such as Figure 7 As shown in the figure, the present invention also discloses an eyebrow shaping method, which mainly includes the following steps:

[0105] S1: The eyebrow trimming operation of the first function is completed by holding the positioning groove of the second handle section. In the state of the first function, the angle limit of the connecting shaft in the connecting seat is maintained at the first angle, and the parallel direction of the blade head provided on the blade body is kept parallel to the tiger's mouth support section.

[0106] S2: By holding the blade, rotating the connecting seat, or pulling or pressing the connecting seat, adjusting its position in the axial length direction, and then performing the rotation operation, and then pressing or pulling in the opposite direction, the second function of eyebrow trimming is completed.

[0107] S3: By holding the blade, push the connecting seat, adjust the engagement position of the limiting block and the fitting block, and complete the eyebrow trimming operation of the third function. The blade and the tiger's mouth support section are not in a parallel position, but have a certain angle limit. The angle limit is that there is a certain relative tilt angle between the blade and the handle.

[0108] Specifically, the first function of eyebrow trimming is performed by holding the positioning part in the first position. In the first position, the connecting shaft in the connecting seat rotates at a first angle, and the blade head and the tiger's mouth of the support part are kept in a parallel line position.

[0109] Specifically, rotate the connecting seat, or adjust it to extend the position of the connecting seat in the axial length direction and then rotate the connecting seat to achieve the second grip position. The handle serves as an auxiliary support. At this time, the eyebrow trimmer maintains the second position state and completes the second function of eyebrow trimming. The blade tip and the web of the hand resting part are not parallel lines, but are offset to a certain extent.

[0110] Specifically, after rotating the connecting seat, adjust and reduce the position of the connecting seat in the axial length direction so that the limiting block and the fitting block can match each other, so that the eyebrow trimmer maintains the third position state. At this time, the tip of the trimmer and the tiger's mouth of the supporting part have a certain tilt angle.
