DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 A razor head assembly comprises a shaving unit 1 and a head cover unit 2 for placing the shaving unit 1, and also comprises: a positioning frame 3, which is installed in the head cover unit 2 and is used to limit the movement of the shaving unit 1 located in the head cover unit 2; the positioning frame 3 comprises a supporting arm 31, and elastic arms 32 are arranged on both sides of the supporting arm 31, and a supporting rod 33 is arranged on the elastic arm 32 for supporting the inner end of the shaving unit 1, and an elastic pressing piece 34 is arranged at one end of the supporting arm 31, and a limiting component 35 is arranged at the other end for fixing the positioning frame 3 in the head cover unit 2.

[0031] When in use, when installing the cutter head assembly, first place the shaving unit 1 in the head cover unit 2, then squeeze the elastic pressing piece 34 by hand, at this time, the elastic pressing piece 34 is deformed by force, that is, the overall width of the positioning frame 3 is narrowed, and the deformation of the elastic pressing piece 34 causes the limiting component 35 to move synchronously, and then the positioning frame 3 is placed in the head cover unit 2, and the elastic pressing piece 34 is released with the cooperation of the head cover unit 2, and the positioning frame 3 can be fixed in the head cover unit 2 through the limiting component 35. At this time, the movement of the shaving unit 1 can be restricted by the positioning frame 3, so that it can be installed in the head cover unit 2 for subsequent use. When disassembling the cutter head assembly, similarly, first squeeze the elastic pressure piece 34 by hand. The elastic pressure piece 34 is deformed by force and drives the limiting component 35 to move together. At this time, the positioning frame 3 is no longer restricted and fixed, so the positioning frame 3 can be taken out from the head cover unit 2, and then the shaving unit 1 can be taken out from the head cover unit 2, thereby realizing the assembly and disassembly of the cutter head assembly. The operation is simple and convenient, without complicated operations, easy to use, and unfamiliar users can also get started quickly, saving a lot of time and energy, and the installation is stable, which greatly avoids the current unstable installation of the cutter head assembly causing the shaving unit 1 to fall off during use, etc., and the use effect is good and the practicability is strong; and the positioning frame 3 is simple to manufacture, low cost, does not require multiple parts, and can be widely promoted and used.

[0032] After the cutter head assembly is installed, the support rod 33 on the positioning frame 3 contacts the inner end of the shaving unit 1 to support the inner end of the shaving unit 1. When the shaving unit 1 is used for shaving, the shaving unit 1 will be forced to float toward the inside of the head cover unit 2, so that the shaving unit 1 will drive the support rod 33 to move, and the elastic arm 32 connected to the support rod 33 will be deformed; then when the shaving unit 1 is not forced, the elastic arm 32 will return to its original state, and the elastic arm 32 will drive the support rod 33 to move, and the shaving unit 1 will move back to its original state, so that the shaving unit 1 can float up and down when in use, so that the user can have a better shaving effect.

[0033] In this embodiment, preferably, please refer to Figure 1-6 A positioning plate 4 is provided on the inner wall of the head cover unit 2, and a positioning groove 5 is opened on the positioning plate 4. The limiting component 35 includes: a connecting plate 351, which is provided on the support arm 31; a limiting block 352, which is provided in the middle of the support arm 31 and is adapted to the positioning groove 5.

[0034] When the elastic pressing piece 34 on the positioning frame 3 is squeezed, the elastic pressing piece 34 will drive the limiting component 35 to move, that is, the connecting plate 351 and the limiting block 352 will move with the elastic pressing piece 34. At this time, the positioning frame 3 is placed in the head cover unit 2, and the limiting block 352 is located in the positioning groove 5 of the positioning plate 4. Then, the elastic pressing piece 34 is released, and the elastic pressing piece 34 will return to its original state, thereby driving the limiting block 352 to move. At this time, the limiting block 352 will enter the positioning groove 5 of the positioning plate 4, and then the positioning frame 3 can be restricted and fixed through the positioning groove 5, thus completing the installation of the positioning frame 3. The operation is simple and convenient, easy to use, saving a lot of time and energy, and having a good use effect.

[0035] In this embodiment, preferably, please refer to Figure 5-6 The elastic pressing piece 34 includes a pressing portion 341 and a deforming portion 342. Both ends of the deforming portion 342 are connected to the pressing portion 341, and the deforming portion 342 is arc-shaped. When pressing the elastic pressing piece 34, the pressing portion 341 of the elastic pressing piece 34 is mainly squeezed by hand. At this time, the pressing portion 341 will drive the deforming portion 342 to deform, that is, the arc of the deforming portion 342 increases, and the distance between the pressing portions 341 decreases, and the pressing portion 341 will drive the limit block 352 to move. When the pressing portion 341 of the elastic pressing piece 34 is released, the deforming portion 342 will return to its original state, and the limit block 352 will also move and return to its original state.

[0036] In this embodiment, preferably, please refer to Figure 3-4 The head cover unit 2 is provided with a positioning hole 7 for correspondingly placing the shaving unit 1. The shaving unit 1 is placed into the positioning hole 7 from the inner side of the head cover unit 2, one end of the shaving unit 1 is exposed from the positioning hole 7 for shaving operation, and the other end is located in the head cover unit 2 and is restricted by the positioning hole 7 to prevent the shaving unit 1 from being separated from the positioning hole 7.

[0037] In this embodiment, preferably, please refer to Figure 1 and Figure 5 A limiting plate 6 is also provided on the connecting plate 351, and the shaving unit 1 is located between the limiting plate 6 and the positioning hole 7. When the shaving unit 1 and the positioning frame 3 are both installed in the head cover unit 2, the limiting plate 6 will block one side of the shaving unit 1, and a certain distance gap will be left between the limiting plate 6 and the shaving unit 1. When shaving is used later, the shaving unit 1 will be forced to float toward the inside of the head cover unit 2. When the shaving unit 1 moves to the limiting plate 6, it will be blocked by the limiting plate 6, thereby preventing the shaving unit 1 from moving too far and ensuring that it floats within a normal range.

[0038] In this embodiment, preferably, please refer to Figure 1 and Figure 3-4The inner wall of the head cover unit 2 is provided with a stopper 8 for limiting the movement range of the shaving unit 1 in the head cover unit 2. The stopper 8 in the head cover unit 2 can directly block and limit the movement of the shaving unit 1, that is, when the shaver is in use, the shaving unit 1 floats along the head cover unit 2, and the stopper 8 serves as the limit position of the movement of the shaving unit 1, thereby ensuring that the shaving unit 1 is used in a floating manner within a normal range.

[0039] In this embodiment, preferably, please refer to Figure 1 and Figure 5 The elastic arm 32 is also provided with a reinforcing plate 9, which is connected to the support rod 33 and provided with a protrusion 10. By providing the reinforcing plate 9 between the upper and lower elastic arms 32, the strength of the elastic arm 32 can be improved, and the toughness and strength of the elastic arm 32 that is deformed by the floating of the shaving unit 1 can be improved, and the performance and life of the positioning frame 3 can be improved. The protrusion 10 can further block and restrict the inner side of the shaving unit 1, and further ensure the use effect of the shaving unit 1.
