Description

Technical Field

[0001] This utility model relates to the field of scissor head technology, and in particular to a structure for an electric clipper scissor head. Background Technology

[0002] With the increasing popularity of electric hair clippers, the technical requirements for electric clippers in the market are gradually increasing, especially in terms of improving cutting accuracy, blade durability, and user comfort. As a common hair-cutting tool, the optimization of the blade head structure plays a crucial role in improving performance and user experience. To meet the needs of different users, modern electric clipper designs often emphasize key indicators such as stability, precision, noise control, and blade life. Therefore, the design and manufacturing of electric clipper heads has become a key area of ​​technological development for electric hair clippers.

[0003] Currently, many electric hair clippers on the market use simple fixing devices for their blades, tightly connecting the moving and fixed blades with screws and the blade holder. Most electric clipper heads utilize springs or other elastic elements to adjust the pressure between the blades, achieving cutting stability and efficiency. Adjustment between the moving and fixed blades is mostly done manually by rotating screws or adjusting knobs. These designs are relatively traditional and can guarantee cutting results to a certain extent, but they do not meet higher standards for precision and stability. Existing technology typically relies on simple mechanical structures with relatively simplistic designs, lacking comprehensive optimization for blade wear, noise, vibration, and other aspects.

[0004] Existing scissor heads have limitations in adjusting the distance between the moving and stationary blades, especially in terms of precision. It is often difficult to precisely control the fit between the moving and stationary blades, which can easily lead to blade loosening or uneven wear, affecting the stability and accuracy of the cutting. Because the distance between the blades is not easily adjusted precisely, this structure can easily result in unstable cutting effects and may even pose a potential safety hazard to the user. Therefore, how to precisely adjust the distance between the moving and stationary blades to ensure high stability and precision during the cutting process has become a major challenge in existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric clipper head structure, which aims to improve the limitations of existing clipper heads in adjusting the distance between the moving blade and the fixed blade. In particular, in terms of adjustment precision, it is often difficult to accurately control the fit between the moving blade and the fixed blade, which can easily lead to loosening of the blade or uneven wear, affecting the stability and accuracy of cutting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric hair clipper head structure, wherein the clipper head is mounted on an electric hair clipper, comprising:

[0007] A fixed blade is adapted to the top base of the electric clipper, and a movable blade is slidably disposed above the fixed blade;

[0008] A moving blade is attached to a blade holder above it, and the blade holder presses down on the moving blade to make the moving blade fit against the fixed blade.

[0009] The copper sleeve is located in the groove inside the tool holder and is prevented from detaching from the tool holder by the pressure of the guide rod.

[0010] A fixing seat is installed at one end of the guide rod, and a pair of screws are used to fix and release one end of the guide rod.

[0011] Furthermore, a second screw is provided inside the fixing seat, and the outer wall of the second screw is threadedly connected to the inside of the fixed blade.

[0012] Furthermore, the outer wall of the screw is threaded into the interior of the fixing seat, and the bottom of the screw fits against the outer wall of the guide rod.

[0013] Furthermore, the interior of the copper sleeve is located on the outer wall of the guide rod, and the copper sleeve is fixed to the tool holder by the pressure applied by the guide rod.

[0014] Furthermore, the outer wall of the guide rod is slidably connected inside the fixed seat to adjust the distance between the teeth of the fixed cutter and the moving cutter.

[0015] Furthermore, the fixed blade and the fixed base are fixedly connected by two screws.

[0016] Furthermore, the fixed blade and the moving blade are fitted together, and an oil storage groove is provided inside the blade holder. Sponge, non-woven fabric, etc. can be placed inside the blade holder.

[0017] Furthermore, the guide rod is composed of a U-shaped spring post.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the precise adjustment of the distance between the moving blade and the fixed blade is achieved through the fixed cooperation of the copper sleeve, the guide rod, and the screw, ensuring the stability during hair cutting. The guide rod can be slidably connected in the fixed seat, and the fit between the moving blade and the fixed blade is adjusted by pressure, making the cutting more precise and improving the durability of the blade. The copper sleeve, through the pressure of the guide rod, keeps the blade holder and the moving blade in close cooperation, preventing the blade from loosening and improving the safety and reliability of cutting.

[0020] 2. In this utility model, lubricating oil is injected into the copper sleeve, which, together with the oil storage tank inside the blade holder and the sponge and non-woven fabric placed inside, effectively reduces blade wear and extends the service life of the blade head. At the same time, the optimized fit design of the moving blade and the fixed blade makes the vibration during the cutting process smaller, which helps to reduce operating noise, improve user comfort, and enhance the user experience.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 3 One embodiment of this utility model provides: a scissor head structure for electric hair clippers, wherein the scissor head is mounted on an electric hair clipper, comprising:

[0028] Fixed blade 1 works in conjunction with moving blade 2 to cut, and is adapted to the top base of the electric clipper. Moving blade 2 is slidably mounted above fixed blade 1.

[0029] The moving blade 2, together with the fixed blade 1, completes the cutting. A blade holder 3 is clamped above the moving blade 2 and is clamped above the moving blade 2 to press down on the moving blade 2 so that it fits into the fixed blade 1 to ensure smooth cutting. The blade holder 3 presses down on the moving blade 2 so that the moving blade 2 fits into the fixed blade 1.

[0030] The copper sleeve 6 is set in the groove inside the tool holder 3 and is prevented from detaching from the tool holder 3 by the pressure of the guide rod 5;

[0031] The fixed base 4 connects to the guide rod 5 and is fixed or released by screw 7. It is set at one end of the guide rod 5 and adjusts the distance between the moving blade 2 and the fixed blade 1 by sliding to optimize the shearing effect and withstand external pressure. It keeps the blade holder 3 and the moving blade 2 in close contact. It is used with screw 7 to fix and release one end of the guide rod 5. The fixed base 4 is equipped with screw 8. The outer wall of screw 8 is threaded to the inside of the fixed blade 1. The outer wall of screw 7 is threaded to the inside of the fixed base 4. The bottom of screw 7 is in contact with the outer wall of the guide rod 5. The inside of the copper sleeve 6 is set on the outer wall of the guide rod 5. The copper sleeve 6 is fixed to the blade holder 3 by the pressure of the guide rod 5. The outer wall of the guide rod 5 is slidably connected to the inside of the fixed base 4 and is used to adjust the distance between the teeth of the fixed blade 1 and the moving blade 2. The fixed blade 1 and the fixed base 4 are fixedly connected by screw 8.

[0032] Specifically, the precise cooperation between the copper sleeve 6 and the guide rod 5 enables accurate adjustment of the distance between the moving blade 2 and the fixed blade 1, ensuring the stability and efficiency of the cutting process. The sliding connection of the guide rod 5 within the fixed base 4 allows users to adjust the fit between the moving blade 2 and the fixed blade 1 as needed, thereby optimizing the haircutting effect. After being fixed by screw 7, the blade position is ensured to be firm and will not shift due to external force or vibration. The copper sleeve 6 is embedded in the outer wall of the guide rod 5, and with the pressure of the guide rod 5, the blade holder 3 and the moving blade 2 are kept in close contact, thereby effectively preventing the blade from loosening or moving, improving the safety and reliability of the cutting process, ensuring not only the accuracy of the haircutting process but also extending the service life of the blade.

[0033] Reference Figure 3 The fixed blade 1 and the moving blade 2 are fitted together. The inside of the blade holder 3 is provided with an oil storage groove. The inside of the blade holder 3 can hold sponges, non-woven fabrics, etc. The guide rod 5 is composed of a U-shaped spring column.

[0034] Specifically, an oil reservoir is specially designed inside the blade holder 3, allowing the placement of lubricating materials such as sponges and non-woven fabrics. This ensures that lubricating oil is continuously supplied to the key components of the blade head, reducing direct friction between metals, improving wear resistance, and extending the life of the blade head. Under the action of lubricating oil, the copper sleeve 6 has smoother contact with the moving blade 2 and the blade holder 3, effectively reducing friction and making the blade head run more smoothly and less prone to jamming. At the same time, the oil reservoir design allows the lubricating oil to be released slowly, ensuring that the blade head maintains proper lubrication during long-term operation, thereby avoiding jamming or blade head damage caused by insufficient lubrication. In addition, the U-shaped spring column structure of the guide rod 5 can also absorb vibration, reducing the noise of the blade head during operation and making the haircutting process quieter and more comfortable.

[0035] Working principle: When the electric hair clipper head structure is needed, the precise distance between the moving blade 2 and the fixed blade 1 is adjusted by the cooperation of the copper sleeve 6 and the guide rod 5. It is best to fix it with screw 7. The guide rod 5 can be slidably connected in the fixed base 4. The fit between the moving blade 2 and the fixed blade 1 is adjusted by pressure to ensure the accuracy and stability during the hair cutting process. In addition, the copper sleeve 6 is embedded in the outer wall of the guide rod 5. Through the pressure of the guide rod 5, the blade holder 3 and the moving blade 2 are kept in close contact, which effectively prevents the blade from falling off, thereby improving the cutting effect and safety.

[0036] In addition, the blade holder 3 has an oil reservoir inside, which can hold lubricating materials such as sponges and non-woven fabrics. This allows the copper sleeve 6 to reduce friction under the action of lubricating oil, extending the service life of the blade head and reducing working noise. The guide rod 5, which is composed of U-shaped spring columns, not only provides elastic adjustment but also buffers vibration in high-intensity working environments, making haircutting smoother and effectively reducing the problem of excessive blade head temperature, thus improving user comfort.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
