It can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0045] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail through the drawings and examples below. However, it should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.
[0046] Example one: refer to Figures 1 to 8A hemispherical intermediate blade assembly for preventing skin scratches includes paired fixing members 1 for shaving long beards, a fixed blade 2 positioned between the fixing members 1, and a movable blade assembly 3 positioned between the fixing members 1 below the fixed blade 2. The movable blade assembly 3 is connected to the fixing members 1 via a reset member 4, which allows the movable blade assembly 3 to automatically return to its original shape after being pressed by external force. The upper surface of the fixed blade 2 is at least one hemispherical, which increases the strength and rigidity of the fixed blade 2, preventing deformation under heavy pressure and thus extending its service life. The spherical design of the fixed blade 2 also enhances the overall three-dimensionality and smoothness of the shaving machine, providing a comfortable and close shave. During use, regardless of the user's pressure or the speed of movement, the spherical design of the fixed blade 2 prevents sharp edges from forming, thus avoiding skin scratches (such as on the face) and ensuring a smooth and effortless shaving experience.
[0047] Example 2: This can be explained based on Example 1, such as... Figures 1 to 9 As shown, the fixed blade component 2 includes a connecting seat 21 for fixing to the opposite fixed component 1. A hemispherical blade body 22 is integrally formed with the upper surface of the connecting seat 21. The hemispherical blade body 22 has a mesh-like design, preventing deformation under heavy pressure and thus extending its lifespan. The hemispherical blade body 22 also enhances the overall three-dimensional feel and provides a smooth and comfortable shaving experience. During use, regardless of the user's pressure or speed, the hemispherical blade body 22 will not have sharp edges, preventing skin abrasions (such as on the face), and provides a smooth and effortless shaving experience, better meeting user needs. Furthermore, the connecting seat 21 has fixing holes 23 for fixing to the fixed component 1, and the fixed component 1 has fixing protrusions. The fixing holes 23 cooperate with the fixing protrusions to fix the connecting seat 21 to the opposite fixed component 1, facilitating installation and disassembly. To further clarify, the hemispherical blade body 22 has at least one hemispherical surface on its upper end. In practice, both the upper and lower ends of the hemispherical blade body 22 can be at least one hemispherical surface, offering a variety of types and a wide range of choices. Finally, it should be emphasized that the connection between the connecting seat 21 and the hemispherical blade body 22 is an arc-shaped connection, preferably with two arc-shaped connections. This facilitates shaving, reduces skin irritation, and ensures more even pressure on the skin, resulting in a more comfortable user experience.

Figures 1 to 9As shown in the figure, the moving cutter assembly 3 comprises a mounting member 31 between the opposite fixed members 1, and the moving cutter 32 is arranged on the mounting member 31. The upper surface of the moving cutter 32 is arranged in an arc shape, which is more conducive to contact with the lower end surface of the hemispherical surface of the fixed cutter member 2, and is more conducive to shaving. Further description, the mounting member 31 comprises a mounting body 311 between the opposite fixed members 1, and the moving cutter 32 is fixed to the upper part of the mounting body 311. The lower part of the mounting body 311 is provided with a mounting groove 312. This kind of arrangement not only facilitates the installation of the moving cutter 32, but also facilitates the installation with the outside through the mounting groove 312. Further description, the mounting body 311 on both sides of the mounting groove 312 is arranged in an outwardly expanding manner, which is more conducive to the mounting body 311 to be more conveniently mounted on the equipment. In this embodiment, the mounting body 311 is in a T shape, which is more conducive to meet the use requirements.
[0049] As shown in the figure, Figures 1 to 9 The reset member 4 adopts a reset spring, which is widely available and easy to implement. Further description, the reset spring adopts two, which is more conducive to the reset of the moving cutter assembly 3. Among them, the mounting body 311 and the fixed member 1 are provided with positioning protrusions for positioning and installing the reset spring. This kind of arrangement is reasonable and conducive to quickly installing the reset spring.
[0050] Example four: can be based on example one or example two or example three, as shown in the figure, Figures 1 to 9 The pair of distributed fixed members 1 adopts two identical fixed seats, which are in an inverted "J" shape. The two identical fixed seats are spaced apart by a certain distance in the middle, and the certain distance in the middle is used for the lower part of the moving cutter assembly 3 to pass through, which is conducive to installation. Further description, the two identical fixed seats are connected through the pressing plate 5, and the pressing plate 5 is also pair-distributed, and the pair-distributed pressing plate 5 is used to connect the two identical fixed seats. The pressing plate 5 is respectively located at the side surface position of the fixed seat. This kind of arrangement not only can play a connecting role, but also can better limit the moving cutter assembly 3 to a certain extent, so it is more conducive to meet the use requirements of users.
