Technical Field
[0001] The present application relates to the technical field of facial shaving tools, and in particular to an anti-deformation eyebrow trimming knife. Background Art
[0002] Neat eyebrows will make the face look more refreshing. Normally grown eyebrows are usually messy. An eyebrow trimmer is a shaving tool used to trim the shape and contour of eyebrows.
[0003] Existing eyebrow trimmers usually consist of a blade, a handle, and a sheath. The blade is clamped and fixed at one end of the handle, and the sheath is placed on the handle to cover the blade. During the eyebrow trimming process, as the eyebrow trimmer moves left and right, the part of the handle that clamps the blade will be continuously subjected to force.
[0004] The handle of an existing eyebrow trimmer is usually made of plastic. After long-term use, the part of the handle that clamps the blade will be repeatedly stressed and fatigue will occur. The handle is prone to cracks and breakage, which affects the service life of the eyebrow trimmer and is not conducive to long-term use of the eyebrow trimmer.
[0005] Therefore, it is urgent to solve the problem that the fixed blade of the eyebrow trimmer is prone to fatigue, thereby improving the stability of the overall structure of the eyebrow trimmer and extending the service life of the eyebrow trimmer. Utility Model Content
[0006] In order to improve the stability of the overall structure of the fixed blade of the eyebrow trimmer, the present application provides an anti-deformation eyebrow trimmer.
[0007] The present application provides an anti-deformation eyebrow trimmer, which adopts the following technical solutions:
[0008] A deformation-resistant eyebrow trimmer comprises a blade and a handle, wherein one end of the handle is provided with a fixing portion, the blade is arranged in the fixing portion, and the cutting edge on the blade protrudes from one side of the fixing portion, the fixing portion comprises a connecting section, the connecting section is fixedly connected to the handle, and a reinforcement member 1 is protruding from one side of the connecting section, and the reinforcement member 1 is located at the connection between the connecting section and the handle and conflicts with the handle.
[0009] By adopting the above technical solution, the blade is arranged in the fixing part and the blade edge protrudes from one side of the fixing part, so that the blade can trim eyebrows smoothly and be stably fixed on the handle. By providing the reinforcement member 1, when using the eyebrow trimmer, the movement of the eyebrow trimmer drives the connecting section to be subjected to a force moving closer to or away from the blade. The handle applies a reaction force to the connecting section through the reinforcement member 1, thereby limiting the influence of the force on the connecting section and making the connecting section balanced in force. The provision of the reinforcement member 1 improves the connection strength between the connecting section and the handle, ensuring that the eyebrow trimmer can be used stably.
[0010] Optionally, the fixing portion further includes a movable section, a second reinforcement member is protruding from a side of the connecting section facing the movable section, and a receiving groove adapted to the second reinforcement member is provided on the movable section.
[0011] By adopting the above technical solution, the second reinforcement member is arranged at the joint between the movable section and the connecting section, thereby improving the overall structural strength of the movable section and the connecting section and ensuring the safety of the eyebrow trimmer.
[0012] Optionally, the blade is clamped between the connecting section and the movable section, a limiting piece is fixedly provided on the side of the connecting section facing the blade, a through hole is provided on the blade for the limiting piece to pass through, and a groove is provided on the movable section to engage with the limiting piece.
[0013] By adopting the above technical solution, the limiting member limits the position of the blade in the fixed part.

The clamping piece 1 is engaged with the clamping groove 1, so that the movable section is firmly fixed on the handle, limiting the influence of the force on the movable section, preventing the movable section from falling off the handle, and improving the overall structural strength of the fixing part.
[0016] Optionally, a protective portion is provided on the fixing portion, the protective portion covers the tail of the blade, and the protective portion on the same side as the blade protrudes from the blade.
[0017] By adopting the above technical solution, the provision of the protective part prevents the blade tail from scratching the skin. When the eyebrow trimmer blade contacts the skin as a whole, the protective part protrudes from the blade edge. Therefore, the protective part contacts the skin first. When trimming eyebrows, the eyebrow trimmer needs to continue to move the eyebrow trimmer closer to the skin, thereby improving the safety of the eyebrow trimmer.
[0018] Optionally, an arc-shaped contact surface is provided at the transition between the protective portion and the blade.
[0019] By adopting the above technical solution, the setting of the arc-shaped contact surface makes it safer for the user to come into contact with the blade head guard part and the blade tail guard part, avoiding the blade head guard part and the blade tail guard part from scratching the skin.

[0021] By adopting the above technical solution, the second clamping member is engaged with the second clamping slot, thereby realizing the installation and removal of the blade cover, and preventing the eyebrow trimmer from scratching the skin during carrying.
[0022] Optionally, a guide groove is provided at the opening of the knife sleeve to facilitate the second clamping member to be clamped into the second clamping slot, and the guide groove is connected to the second clamping slot.
[0023] By adopting the above technical solution, the guide groove is arranged at the opening of the knife sleeve, which guides the second clamping member to penetrate into the second clamping groove, making it easier to cover the knife sleeve on the fixed part.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. The blade is arranged in the fixing portion, and the blade edge protrudes from one side of the fixing portion, so that the blade can trim eyebrows smoothly and is stably fixed to the handle. By providing the reinforcement member 1, when the eyebrow trimmer is used, the movement of the eyebrow trimmer drives the connecting section to be subjected to the force moving toward or away from the blade. The handle applies a reaction force to the connecting section through the reinforcement member 1, limiting the impact of the force on the connecting section, so that the force on the connecting section is balanced. The provision of the reinforcement member 1 improves the connection strength between the connecting section and the handle, ensuring the stable use of the eyebrow trimmer;
[0026] 2. The second reinforcement is set at the joint of the movable section and the connecting section, which improves the overall structural strength of the movable section and the connecting section and ensures the safety of eyebrow trimmer use;
[0027] 3. The blade is clamped between the connecting section and the movable section. When the eyebrow trimmer is in use, the blade exerts force in two directions on the movable section, causing the movable section to move closer to or away from the connecting section. The clamping piece 1 is engaged with the clamping groove 1, so that the movable section is firmly fixed on the handle, limiting the influence of the force on the movable section, preventing the movable section from falling off the handle, and improving the overall structural strength of the fixing part.

[0033] Example:
[0034] A deformation-proof eyebrow trimmer, reference Figure 1 and Figure 2 The eyebrow trimmer includes a handle 1 and a blade 2 fixed on the handle 1. One end of the handle 1 is provided with a fixing portion 3 for fixing the blade 2. The fixing portion 3 includes a connecting section 4 and a movable section 5. The connecting section 4 and the movable section 5 clamp the blade 2 therein. The connecting section 4 and the handle 1 are fixed together by ultrasonic welding and then combined. Figure 3 The movable section 5 is integrally formed with a clamping piece 6, which is a protrusion formed by the movable section 5 protruding outward on the side of the handle 1. A clamping groove 7 is provided on one side of the handle 1 to engage with the clamping piece 6. The clamping piece 6 engages with the clamping groove 7 to achieve the fixed connection between the movable section 5 and the handle 1. The two sides of the blade 2 respectively contact the connecting section 4 and the movable section 5. When the eyebrow trimmer is in use, the blade 2 exerts a force on the movable section 5, causing the movable section 5 to approach or move away from the connecting section 4. The clamping piece 6 engages with the clamping groove 7 to limit the influence of the force on the movable section 5, so that the movable section 5 is firmly fixed on the handle 1 and prevents the movable section 5 from falling off the handle 1.
