[0027] An embodiment of the present utility model provides a double-sided blade structure, in combination with Figure 1 , Figure 2 , Figure 3 As shown, it includes a blade holder 1 and a connecting piece 2 adapted to be connected to a knife handle main body 3. Blades 4 are respectively arranged on the front and rear sides of the blade holder 1, and the blade holder 1 is detachably connected to the connecting piece 2.
[0028] Among them, the blade holder 1 is usually made of a durable and lightweight material, such as plastic or metal alloy. Each of the front and rear sides of the blade holder 1 is provided with a blade mounting area for mounting the blade 4; the blade 4 is usually a sharp metal sheet for shearing or trimming hair; the connecting piece 2 is an intermediate part for connecting the blade holder 1 and the knife handle main body 3, and is usually designed to be swingably connected to the knife handle main body 3 in the front and rear directions to adapt to different shaving angles.
[0029] In the double-sided cutter head structure of this embodiment, the cutter head bracket 1 and the connecting member 2 are detachably connected, making it simple and convenient to replace the blade 4. The user can easily remove the cutter head bracket 1 to replace or clean the blade 4, maintaining the hygiene and good condition of the cutter head. When the blade 4 is worn or damaged, the user can easily remove the cutter head bracket 1 and replace it with a new blade 4 without replacing the entire cutter head structure, saving costs and resources and extending the service life and durability of the entire double-sided cutter head.
[0030] Optionally, as shown in Figure 3 , the cutter head bracket 1 is provided with a first magnetic member 5, and the connecting member 2 is provided with a second magnetic member 6 that magnetically adsorbs to the first magnetic member 5. The first magnetic member 5 and the second magnetic member 6 are preferably both magnets, which play a role of alignment and guidance through magnetic adsorption, and a firm connection is formed between the cutter head bracket 1 and the connecting member 2, making it not easy to loosen or fall off, ensuring the stability and safety of the cutter head. In addition, although magnetic adsorption can keep the connection firm, it is not overly tight, facilitating the user to easily disassemble the cutter head bracket 1 for blade 4 replacement or cleaning and maintenance. When the user replaces the blade 4 or performs maintenance, no tools or complex operation steps are required. Just by utilizing the characteristics of magnetic adsorption, the disassembly and reassembly can be completed, improving the convenience and efficiency of the operation.
[0031] Optionally, as shown in Figures 1 to 7 , the connecting member 2 is hingedly connected to the handle main body 3, that is, the connecting member 2 can rotate or swing on the handle main body 3. The hinge component can be a bearing, a pin shaft or other types of hinge structures. The hinged connection enables the cutter head bracket 1 to rotate or adjust the angle relatively freely on the handle main body 3, improving the operation flexibility and comfort during trimming. The user can adjust the angle and position of the cutter head bracket 1 according to specific trimming requirements to obtain a better trimming effect, especially when dealing with different parts and curves, which is more convenient. The design of the hinged connection can also make the posture during trimming more natural and comfortable, reducing the fatigue of the user's hand or wrist and improving the user experience.
[0032] Optionally, as shown in Figure 2 , Figure 4 , Figure 5 , Figure 6 , one side of the connecting member 2 is provided with a first buckle position 21, the cutter head bracket 1 is provided with a second buckle position 11 that cooperates with the first buckle position 21, the side of the connecting member 2 away from the first buckle position 21 is provided with a suspended portion 22, and the handle main body 3 is floatingly connected with a support tongue 7 adapted to abut and cooperate with the suspended portion 22.
[0033] Among them, the cooperative design of the first buckle position 21 and the second buckle position 11 ensures the correct assembly and positioning of the cutter head holder 1 on the connecting piece 2, avoids errors and instabilities during assembly, plays a role in strengthening the fixation of the cutter head, and prevents the cutter head from falling out during shaving due to too short a magnetic attraction stroke; the suspension part 22 and the first buckle position 21 are respectively located on the front and back sides of the connecting piece 2, and the suspension part 22 is used to cooperate with the support tongue 7 on the handle body 3. The starting rotation position of the connecting piece 2 relies on the support tongue 7 for support, playing a role in adjusting the shaving angle; the floating connection on the handle body 3 enables the entire double-sided cutter head structure to be finely adjusted or adjusted when needed to adapt to different trimming angles and requirements.
[0034] Optionally, as shown in Figure 1 、 Figure 3 , a reset member 8 is provided between the support tongue 7 and the handle body 3. The upper and lower ends of the reset member 8 are respectively connected to the support tongue 7 and the handle body 3 to realize the floating setting of the support tongue 7. The reset member 8 is preferably a compression spring, and its upper and lower ends respectively abut against the support tongue 7 and the handle body 3, which is used for the floating setting and position control of the support tongue 7, so that the support tongue 7 can make small floating or adjustments within a certain range, and flexibly adjust the angle and position of the cutter head according to trimming requirements.
[0035] Optionally, as shown in Figure 1 、 Figure 6 、 Figure 7 , the surface of the suspension part 22 in contact with the support tongue 7 is an arc surface, and / or the surface of the support tongue 7 in contact with the suspension part 22 is an arc surface, so that when the support tongue 7 contacts the suspension part 22, a line contact can be formed instead of a plane contact. The contact area is small, reducing the friction between the support tongue 7 and the suspension part 22, reducing the possibility of wear and damage, and extending the service life of the components; when the connecting piece 2 rotates relative to the handle body 3, the support tongue 7 can smoothly slide back and forth relative to the support tongue 7 while swinging up and down, ensuring the smooth rotation of the cutter head holder 1 relative to the handle body 3.
[0036] Optionally, as shown in Figure 1 、 Figure 2 、 Figure 4 , the second buckle positions 11 are respectively provided on the front and rear inner walls of the cutter head holder 1, and the two second buckle positions 11 are symmetrically arranged, that is, the positions of the two second buckle positions 11 on the inner wall of the cutter head holder 1 are relatively symmetrical, realizing that the cutter head holder 1 can be installed with the front and back reversed, improving the assembly efficiency.
[0037] Optionally, as shown in Figure 5 、 Figure 6 、 Figure 7As shown, hinged columns 23 are respectively provided on the left and right sides of the connecting member 2, and the handle body 3 is provided with a slide rail 31 which is slidably connected to the hinged column 23 up and down, and the hinged column 23 is hingedly connected to the slide rail 31; the design of the slide rail 31 allows the hinged column 23 to slide up and down along the slide rail 31 in a vertical direction, thereby adjusting the angle and height position of the double-sided cutter head to meet different pruning requirements.
[0038] Optionally, combined Figure 5 , Figure 7 As shown, the handle body 3 is provided with a support column 32, the slide rail 31 is provided on the inner side wall of the support column 32, a transition notch 321 is provided on the support column 32 near the slide rail 31, and the hinge column 23 is provided with a guide slope 231 suitable for sliding cooperation with the transition notch 321; it is convenient to smoothly assemble the hinge column 23 into the slide rail 31, and the assembly efficiency is improved. As long as the guide slope 231 is aligned with the transition notch 321 and an external force is applied in the direction of the slide rail 31, the hinge column 23 can be smoothly installed into the slide rail 31.
[0039] The process of inserting the cutter head support 1 into the cutter handle body 3:
[0040] The handle body 3 and the connecting piece 2 are hingedly connected to each other, and the initial rotation position of the connecting piece 2 is supported by the supporting tongue 7 to adjust the shaving angle; when the cutter head bracket 1 is inserted into the connecting piece 2, the first magnetic piece 5 and the second magnetic piece 6 attract each other, playing a role in positioning and guiding; when the first magnetic piece 5 and the second magnetic piece 6 are about to fit together, the first buckle position 21 on the connecting piece 2 will buckle into the second buckle position 11 of the cutter head bracket 1, playing a role in strengthening the fixation of the cutter head and preventing the cutter head bracket 1 from falling out during shaving due to the short magnetic suction stroke.
[0041] The process of the cutter head support 1 being separated from the cutter handle body 3:
[0042] The cutter head support 1 can be directly pulled out relative to the handle body 3 along the up-down direction.
