[0028] Reference Figures 1 to 3According to an embodiment of the utility model, a flip-top manual razor for easy blade replacement includes a handle 100, a blade holder 200, a blade cover 400 and a blade 310. The blade holder 200 is arranged on the handle 100, and an avoidance groove 210 is arranged on the front edge of the blade holder 200; the rear end of the blade cover 400 is rotatably installed on the blade holder 200, and the front end of the blade cover 400 is protrudingly provided with an operating part 410, and the operating part 410 is inserted into the avoidance groove 210. A magnetic attraction structure is arranged between the blade cover 400 and the blade holder 200, and the magnetic attraction structure can drive the blade cover 400 and the blade holder 200 to close together, wherein the operating part 410 is used to operate the blade cover 400 to rotate and open relative to the blade holder 200; the blade 310 is detachably placed on the blade holder 200, and the blade 310 can be clamped and fixed by the blade holder 200 and the blade cover 400. Among them, it can be imagined that in order to avoid the blade cover 400 and the blade holder 200 from being separated during the use of the manual razor, the suction force of the magnetic structure needs to be large enough so that the blade cover 400 and the blade holder 200 can be firmly closed together, and the setting of the operating part 410 can provide the user with a force point for flipping the blade cover 400, so that the user can more easily overcome the suction force of the magnetic structure and flip the blade cover 400 open by turning or prying the operating part 410.

[0029] The flip-top manual razor provided by the utility model has an operating portion 410 protruding toward the blade holder 200 and inserted into the avoidance groove 210 during the process of replacing the blade 310. The user can flip the blade cover 400 open by turning or bending the operating portion 410, thereby overcoming the suction force of the magnetic attraction structure and making it easier to flip and open the blade cover 400. After flipping and opening the blade cover 400, the blade 310 can be taken out. After the blade 310 is placed on the blade holder 200 again, the blade cover 400 only needs to be rotated toward the blade holder 200 to be closed together with the blade holder 200 through the magnetic attraction structure, and the blade cover 400 and the blade holder 200 can cooperate with each other to clamp and fix the blade 310. With the above arrangement, the flip-top manual razor provided by the utility model can improve the convenience of replacing the blade 310, and the blade 310 is more convenient to replace. There is no need for a complex transmission structure to drive the blade cover 400 to rotate, and the overall structure can be kept as simple as possible.

[0030] Among them, by setting the avoidance groove 210, the blade holder 200 can be prevented from hindering the user from turning or bending the operating part 410, and the operating part 410 can be accommodated when the blade cover 400 is closed on the blade holder 200 to prevent the operating part 410 from affecting the operation of the manual razor.

[0031] Reference Figure 1 and Figure 2According to some embodiments of the utility model, two operating parts 410 are provided, and two avoidance grooves 210 are provided, and the two operating parts 410 are inserted into the two avoidance grooves 210 in a one-to-one correspondence. Through the above arrangement, the two operating parts 410 can be symmetrically arranged to ensure that the overall appearance of the knife cover 400 is better. In addition, when it is necessary to rotate and open the knife cover 400, the user's thumb and index finger can be hooked on the lower sides of the two operating parts 410 respectively to pry the two operating parts 410 at the same time, thereby making it easier to overcome the suction force of the magnetic suction structure to flip the knife cover 400 open, and it can also reduce the situation where the single operating part 410 is subjected to excessive force, resulting in damage to the knife cover 400.

[0032] Reference Figure 1 and Figure 2 According to some embodiments of the utility model, the front edge of the blade 310 has a cutting edge 311, the front edge of the blade 310 is located between the two operating parts 410, a portion of the blade 310 is located above the avoidance groove 210, and a portion of the blade 310 is located above the avoidance groove 210. With the above arrangement, during the process of replacing the blade 310, the portion of the blade 310 that can be located above the avoidance groove 210 can be grasped by the user, so that the blade 310 can be conveniently taken and placed. In the process of using the manual razor, the two operating parts 410 can also play a protective role, preventing the portion of the blade 310 located above the avoidance groove 210 from contacting and scratching the skin.

[0033] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, the magnetic attraction structure includes a magnetic portion 520 and a magnet 510. One of the magnetic portion 520 and the magnet 510 is arranged on the knife cover 400, and the other is arranged on the knife seat 200. The magnet 510 and the magnetic portion 520 can attract each other. Therefore, the suction force between the magnet 510 and the magnetic portion 520 can drive the knife cover 400 and the knife seat 200 to be firmly closed together.

[0034] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, a mounting hole 220 is provided on the knife seat 200, the magnet 510 is embedded in the mounting hole 220, the magnetic part 520 is provided on the knife cover 400, and when the knife cover 400 and the knife seat 200 are closed together, the magnetic part 520 is inserted into the mounting hole 220. With the above arrangement, the magnetic part 520 can cooperate with the side wall of the mounting hole 220 to form a limiting effect, thereby reducing the occurrence of the knife cover 400 being offset or shaking relative to the knife seat 200.

[0035] In some embodiments, the magnetic portion 520 is configured as a magnetic bolt, and the magnetic bolt is screwed to the blade cover 400. With the above configuration, the installation of the magnet 510 and the magnetic bolt is relatively convenient.

[0036] In a specific implementation process, the magnetic attraction structure mentioned above can be provided in one group or more than two groups, and each group of magnetic attraction structures can include a magnet 510 and a magnetic part 520 .

The rear end of the knife cover 400 is provided with a mounting portion 430, and the mounting portion 430 is provided with an axial hole 431. A rotating shaft 800 is rotatably mounted in the axial hole 431. The left and right ends of the rotating shaft 800 can be relatively telescopic, and the left and right ends of the rotating shaft 800 are correspondingly inserted into the two clamping holes 231. With the above arrangement, the knife cover 400 can be conveniently rotatably mounted on the knife seat 200, thereby improving assembly efficiency.

[0040] Reference Figure 5 In the specific implementation process, the rotating shaft 800 includes a shaft cylinder 810, two clamping columns 820 and an elastic member 830, wherein one clamping column 820 is inserted into the left end of the shaft cylinder 810 so as to slide left and right, and the other clamping column 820 is inserted into the right end of the shaft cylinder 810 so as to slide left and right. The elastic member 830 is arranged in the shaft cylinder 810, and the elastic member 830 is located between the two clamping columns 820 and abuts against the two clamping columns 820, so that the two clamping columns 820 can slide and retract relatively. With the above arrangement, the rotating shaft 800 can be retracted and retracted relatively at both ends while ensuring that the rotating shaft 800 has sufficient strength.

[0041] Of course, in other embodiments, the above-mentioned rotating shaft component 800 may also be arranged in other ways. For example, the rotating shaft component 800 includes a sleeve, a shaft column and an elastic component 830. The right end of the shaft column can be slidably inserted into the left end of the sleeve. The elastic component 830 is arranged in the sleeve. The elastic component 830 can drive the shaft column to slide and extend relative to the sleeve, thereby, the left end of the shaft column and the right end of the sleeve can slide and retract relative to each other.

[0042] Of course, it is conceivable that in other embodiments, the above-mentioned flip-type manual razor can also be a double-edged razor. In this case, the blade 310 can be set to be double-edged, and the front and rear edges of the blade 310 both have blades 311. Connecting feet are provided on the left and right corners of the rear end of the blade cover 400. The blade cover 400 is rotatably connected to the blade holder 200 through the two connecting feet. The rear edge of the blade 310 is located between the two connecting feet. The above-mentioned magnetic attraction structure is provided in two groups, and the blade 310 is located between the two groups of magnetic attraction structures.

[0043] According to some embodiments of the present invention, the knife seat 200 is screwed to the handle 100 , so that the knife seat 200 and the handle 100 can be disassembled and assembled, and the disassembly and assembly are convenient.

[0044] It should be noted that, in other embodiments, the knife seat 200 and the handle 100 may also be integrally formed, or the knife seat 200 may be plugged into the handle 100 via a plug-in structure.

[0045] Reference Figure 1 and Figure 3 According to some embodiments of the utility model, the blade holder 200 is rotatably mounted with a lubricating column 600, which is located below the cutting edge 311 of the blade 310, and there is a gap between the lubricating column 600 and the cutting edge 311 of the blade 310. By setting the lubricating column 600, the sliding contact between the blade holder 200 and the skin can be changed into a rolling contact between the lubricating column 600 and the skin, thereby reducing the resistance between the blade holder 200 and the skin during the use of the manual razor, making the use of the manual razor smoother and providing a better experience.
