Technical Field
[0001] This utility model belongs to the technical field of electric clipper heads, specifically relating to an adjustment structure for an electric clipper head. Background Technology
[0002] As a core tool in the fields of hairdressing, styling, and pet hair trimming, the technological development of electric clippers directly affects trimming efficiency, precision, and user experience. With the growing demand for personalized styling in the consumer market, the functional iteration of electric clippers exhibits two major trends: first, the power system is developing towards higher speeds, lower noise, and longer battery life; second, the blade adjustment technology is evolving towards refinement, intelligence, and stepless operation. Among these, the blade adjustment structure, as a key module determining trimming length, shearing force, and blade life, has seen breakthroughs in its technological bottlenecks become a focal point of industry innovation.
[0003] Traditional electric hair clipper heads have two adjustment mechanisms. One mechanism uses the force difference generated by the different deformation angles of the intermediate rod of the torsion spring at the front and rear positions to allow the upper blade to spring back freely to its initial rear position after being pushed to the front. The other mechanism requires manual adjustment to each position, and manual adjustment is also required to return to the corresponding position. However, these traditional adjustment mechanisms are prone to the following drawbacks: First, the pressure between the upper and lower blades varies at the front, middle, and rear ends, resulting in significant differences in cutting performance and blade temperature rise at each setting. Second, manual adjustment is quite strenuous. Therefore, it is necessary to improve the adjustment mechanism of traditional electric hair clippers. Summary of the Invention
[0004] I. Technical problems to be solved
[0005] This utility model addresses the aforementioned deficiencies in the existing technology by proposing an electric clipper head adjustment structure, which solves the problem that the adjustment of the moving blade assembly of existing electric clippers is inconvenient and laborious.
[0006] II. Technical Solution
[0007] To solve the above-mentioned technical problems, the present invention provides an electric clipper head adjustment structure, including a fixed blade base, a movable blade holder fixedly connected to the fixed blade base, a movable blade assembly movably connected to the movable blade holder, and an adjustment mechanism for adjusting the position of the movable blade assembly on the fixed blade base is provided between the fixed blade base and the movable blade holder.
[0008] The adjustment mechanism includes a rotating shaft located in the middle of the moving tool holder, an adjustment lever rotatably connected to the rotating shaft, and an arc-shaped eccentric groove on the adjustment lever;
[0009] The moving tool assembly includes a sliding block that can move along the moving tool holder, and a fixed post that engages with an eccentric groove is provided at the bottom center of the sliding block.
[0010] When the adjusting lever is rotated in one direction, the fixed column moves towards or away from the rotation axis under the contact of the eccentric groove, thereby driving the movement of the sliding block.
[0011] The sliding block is equipped with a torsion spring, and the outer end of the torsion spring is connected to a clamping block. The clamping block is connected to a moving blade, and the moving blade is pressed onto the fixed blade base by the torsion spring.
[0012] The moving tool holder has a sliding groove along its center line for the fixed column to move back and forth.
[0013] The fixed column, rotating shaft, and sliding groove are all located on the center line of the moving tool holder.
[0014] The sliding groove has guide grooves on both sides that are in the same direction as the movement of the fixed column, and guide blocks that slide in cooperation with the guide grooves are provided on both sides of the bottom of the sliding block.
[0015] The adjustment lever is fan-shaped, and an adjustment block is provided at the rear end of the adjustment lever.
[0016] The rear end of the moving tool holder is provided with a movable groove through which the adjusting block passes and slides.
[0017] A limit spring assembly is also provided between the moving tool holder and the adjusting lever. The limit spring assembly includes a spring and a steel ball.
[0018] The moving blade holder is provided with a positioning hole to accommodate the limit spring assembly, and the adjusting paddle is provided with several continuous grooves. The spring can make the steel ball abut against the grooves, so as to realize the shifting effect by moving the adjusting paddle.
[0019] The outer periphery of the adjusting lever is provided with anti-slip texture.
[0020] III. Beneficial Effects
[0021] Compared with the prior art, this utility model uses a sliding groove set on the center line of the moving blade holder, and a fixed column slidably connected inside the sliding groove, so that the moving blade assembly moves linearly along the center line of the moving blade holder, thereby changing the position of the moving blade assembly relative to the fixed blade base, and finally achieving the effect of adjusting the position of the electric clipper head, thus achieving different cutting effects.
[0022] By using the eccentric groove and the fixed column, rotating the adjustment lever can drive the moving blade assembly to move linearly, avoiding the laborious operation of repeated manual adjustment, making the adjustment effortless and efficient.
[0023] Furthermore, the moving blade is pressed against the fixed blade base by a torsion spring, ensuring uniform pressure between the blades at each gear position, reducing temperature rise differences and shearing performance fluctuations, and stabilizing shearing pressure. The fixed column, rotating shaft, and sliding groove are all located on the center line of the moving blade holder, and together with the guide groove and guide block, ensure that the moving blade assembly moves in a straight line without deviation, resulting in high overall motion accuracy. The steel ball of the limit spring assembly abuts against the groove, giving the adjustment lever a shifting feel when rotating, avoiding misoperation, and making the gear position clear. The adjustment lever has anti-slip texture and is exposed in the movable groove, making it easy for users to apply force for adjustment and making operation more convenient.

[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model. Example 1
[0037] Combination Figure 1 , Figure 2 As shown, the electric clipper head adjustment structure of this embodiment includes a fixed blade base 1, a movable blade holder 2 fixedly connected to the fixed blade base 1, a movable blade assembly 3 movably connected to the movable blade holder 2, and an adjustment mechanism 4 for adjusting the position of the movable blade assembly 3 on the fixed blade base 1 is provided between the fixed blade base 1 and the movable blade holder 2.
[0038] Specifically, the fixed blade base 1 is the basic component of the entire electric clipper head adjustment structure. The moving blade holder 2 is fixedly connected to the fixed blade base 1. The position of the moving blade holder 2 relative to the fixed blade base 1 is fixed. The moving blade holder 2 serves as the mounting carrier for the moving blade assembly 3, providing a movable connection position for the moving blade assembly 3. That is, the moving blade holder 2 is fixed on the fixed blade base 1 and cannot move. The moving blade assembly 3 is movably connected to the moving blade holder 2 through the sliding block 31.
[0039] The moving blade assembly 3 is movably connected to the moving blade holder 2, allowing it to reciprocate within a certain range on the moving blade holder 2. The adjusting mechanism 4 is located between the fixed blade base 1 and the moving blade holder 2, or integrated within the moving blade holder 2. Its function is to adjust the position of the moving blade assembly 3 on the fixed blade base 1. By operating the adjusting mechanism 4, the relative position of the moving blade assembly 3 with respect to the fixed blade base 1 can be changed, thereby adjusting the cutting effect of the electric clipper, such as adjusting the cutting length.
[0040] When it is necessary to adjust the position of the moving blade assembly 3 on the fixed blade base 1, the adjustment mechanism 4 is operated. Operating the adjustment mechanism 4 will cause it to perform corresponding actions, such as extension, rotation, etc., which will drive the moving blade holder 2 or directly act on the moving blade assembly 3, so that the position of the moving blade assembly 3 relative to the fixed blade base 1 changes, and finally achieves the purpose of adjusting the cutting effect of the electric clipper.
[0041] Combination Figure 6 As shown, the moving blade assembly 3 includes a sliding block 31 that moves along the centerline of the moving blade holder 2. A torsion spring 32 is mounted on the sliding block 31. A clamping block 33 is connected to the outer end of the torsion spring 32. A moving blade 34 is connected to the clamping block 33.
[0042] Specifically, the sliding block 31 can move along the centerline of the moving blade holder 2, allowing it to change its position along a specific straight trajectory. A torsion spring 32 is mounted on the sliding block 31, and a clamping block 33 is connected to the outer end of the torsion spring 32, establishing a connection between them. The clamping block 33 can move under the action of the torsion spring 32. The moving blade 34 is connected to the clamping block 33 and is the part of the moving blade assembly 3 that directly participates in the shearing operation. The moving blade 34 moves with the movement of the clamping block 33. That is, the inner end of the torsion spring 32 is fixed to the sliding block 31, and the outer end pushes the clamping block 33 to press the moving blade 34 against the fixed blade base 1, ensuring a tight fit of the blade during shearing.
[0043] Combination Figure 3 As shown, the adjustment mechanism 4 includes a rotating shaft 41 located at the center of the moving tool holder 2. An adjustment lever 42 is rotatably connected to the rotating shaft 41. An arc-shaped eccentric groove 43 is provided on the adjustment lever 42. A fixed post 311 is provided at the bottom center of the sliding block 31, which is inserted and engaged with the eccentric groove 43.
[0044] Specifically, the rotating shaft 41 is located at the center of the moving tool holder 2, and the adjusting plate 42 is rotatably connected to the rotating shaft 41, allowing it to rotate around the shaft 41. The position of the moving tool assembly 3 is adjusted by rotating the adjusting plate. An eccentric groove 43, in the shape of an arc, is formed on the adjusting plate 42. The center of the eccentric groove 43 does not coincide with the axis of the rotating shaft 41; this eccentric design is a key structural feature that enables the adjusting mechanism 4 to achieve position adjustment.
[0045] The fixed post 311 is located at the bottom center of the sliding block 31. Its shape and size are compatible with the eccentric groove 43 on the adjusting lever 42, allowing it to be embedded in the eccentric groove 43 and slide relative to it within the groove 43. The fixed post 311 serves as a connection and transmission component between the sliding block 31 and the adjusting lever 42, transmitting the movement of the adjusting lever 42 to the sliding block 31.
[0046] When the adjusting lever 42 is not operated, it is in an initial position. At this time, the fixed post 311 is located in a specific position within the eccentric groove 43, and the sliding block 31 and the entire moving tool assembly 3 are also in their corresponding initial positions. When it is necessary to adjust the position of the moving tool assembly 3, the adjusting lever 42 is manually rotated to make it rotate around the rotation axis 41. The fixed post 311 is embedded in the eccentric groove 43. As the position of the eccentric groove 43 changes, the fixed post 311 will be pushed by the side wall of the eccentric groove 43. This pushing force is decomposed into a component force along the centerline of the moving tool holder 2, thereby pushing the sliding block 31 to move along the centerline of the moving tool holder 2. Because the sliding block 31 is part of the moving tool assembly 3, its movement will cause the entire moving tool assembly 3 to change its position on the fixed tool base 1.
[0047] When the adjusting lever 42 is rotated to the desired position, causing the moving blade assembly 3 to reach the ideal cutting position, the rotation of the adjusting lever 42 is stopped. At this time, the fixed column 311 is in a new stable position within the eccentric groove 43, and the sliding block 31 and the moving blade assembly 3 are also fixed in the new position. The electric clipper can then operate in this adjusted state. When the adjusting lever 42 rotates, the eccentric groove 43 pushes the fixed column 311 to move along the sliding groove 21, while the guide block 312 slides within the guide groove 22, constraining the movement trajectory of the sliding block 31.
[0048] Combination Figure 2 , Figure 3 and Figure 5 As shown, a sliding groove 21 is provided along the center line of the moving tool holder 2 for the fixed column 311 to move back and forth.
[0049] Specifically, a sliding groove 21 is specially formed on the moving tool holder 2 along its centerline. The width of the sliding groove 21 is designed to match the diameter of the fixed column 311 to ensure that the fixed column 311 can move smoothly back and forth within the groove, ensuring the stability of the movement. The length of the sliding groove 21 is determined according to the adjustment range of the moving tool assembly 3, providing sufficient space for the movement of the fixed column 311. The fixed column 311 is embedded in the sliding groove 21, and the two form a sliding fit relationship, so that the fixed column 311 can only move linearly along the centerline of the moving tool holder 2 within the range defined by the sliding groove 21.
[0050] Combination Figure 4 and Figure 5 As shown, the fixed column 311, rotating shaft 41, and sliding groove 21 are all located on the center line of the moving tool holder 2. The fixed column 311 is part of the sliding block 31 in the moving tool assembly 3 and is located on the center line of the moving tool holder 2. Its shape is usually cylindrical, and its diameter is adapted to the size of the relevant mating parts to ensure smooth and stable movement. The function of the fixed column 311 is to serve as the key point of connection and transmission between the moving tool assembly 3 and the adjusting mechanism 4, transmitting the motion generated by the adjusting mechanism 4 to the moving tool assembly 3.
[0051] The rotating shaft 41 is set on the center line of the moving tool holder 2. It provides a central reference for the rotation of the adjusting lever 42, so as to ensure that the adjusting lever 42 can rotate smoothly and accurately around it, thereby achieving precise adjustment function.
[0052] The sliding groove 21 is an elongated groove along the centerline of the moving tool holder 2. Its width matches the diameter of the fixed column 311, allowing the fixed column 311 to slide freely back and forth within the groove. Guide grooves 22 are provided on both sides of the sliding groove 21, aligned with the direction of movement of the fixed column 311. Guide blocks 312, which slide and engage with the guide grooves 22, are provided on both sides of the bottom of the sliding block 31. The sliding groove 21, along the centerline of the moving tool holder 2, provides the main space for the reciprocating movement of the fixed column 311, and its length determines the adjustable position range of the fixed column 311 and the moving tool assembly 3.
[0053] The guide grooves 22 are symmetrically opened on both sides of the sliding groove 21. The direction of the guide grooves 22 is consistent with the moving direction of the fixed column 311, that is, along the center line of the moving tool holder 2. It is adapted to the guide block 312 to ensure that the guide block 312 can slide smoothly in it.
[0054] The rear end of the adjusting lever 42 is provided with an adjusting block 421, and the outer periphery of the adjusting block 421 is provided with anti-slip texture. The shape design may be optimized according to the overall structure and ease of operation of the electric clipper, and may have a certain curvature or special contour to facilitate installation and cooperation with other components. The adjusting lever 42 is mounted on the fixed structure of the electric clipper via a rotating shaft 41, and can move in a circular motion around the rotating shaft 41 to achieve the adjustment function.
[0055] The adjustment lever 421 is positioned at the rear end of the adjustment lever 42 to take into account the convenience of operation and ergonomic principles, so that the user can apply force more comfortably and effortlessly when adjusting.
[0056] Anti-slip textures are applied to the outer periphery of the adjustment lever 421. These textures come in various shapes and arrangements, commonly including straight lines, wavy lines, and grid patterns. The main function of the anti-slip textures is to increase the friction on the surface of the adjustment lever 421. When the user moves the adjustment lever 421 by hand, the anti-slip textures prevent fingers from slipping, ensuring accurate adjustment.
[0057] The rear end of the moving tool holder 2 is provided with a movable groove 23 for the adjusting block 421 to pass through and slide within. The movable groove 23 is located at the rear end of the moving tool holder 2, and its dimensions are designed to fit the adjusting block 421. The width of the movable groove 23 is slightly larger than the thickness of the adjusting block 421 to ensure that the adjusting block 421 can slide smoothly within it; the length is determined according to the range of movement of the adjusting block 421 to provide sufficient space for the sliding of the adjusting block 421. Example 2
[0058] Compared to Example 1, such as Figure 4 and Figure 6As shown, a limiting spring assembly 5 is also provided between the moving blade holder 2 and the adjusting paddle 42. The limiting spring assembly 5 includes a spring 51 and a steel ball 52. The moving blade holder 2 is provided with a positioning hole 53 to accommodate the limiting spring assembly 5. The adjusting paddle 42 is provided with a number of continuous grooves 54. The spring 51 can make the steel ball 52 abut against the grooves 54, so as to realize the shifting effect of moving the adjusting paddle 42.
[0059] When the adjustment lever 42 rotates, the steel ball 52 is engaged in different grooves 54 under the action of the spring 51, thus achieving gear positioning. When the adjustment lever 421 is moved to an adjacent groove 54, a distinct shifting feel is produced.
[0060] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
