At the same time, the direction of the gap can also be changed, that is, adjusting the connection line ( Figure 1 , Figure 2 The inclination angle of the first blade 231 (the dotted line in the figure) is adjusted to indirectly adjust the shaving angle of the first blade 231 on the skin between the front edge of the first base 300 and the first blade 231 to meet the usage requirements of skin with different sensitivities, thereby improving the usage experience.

[0031] Reference Figure 1 and Figure 2 When the first base 300 is driven to move forward by the adjusting device 400, the opening of the gap between the front edge of the first base 300 and the first blade 231 is larger to meet the use needs of thicker hair. At the same time, the closer the line between the front edge of the first base 300 and the first blade 231 is to the front-to-back direction, that is, the smaller the shaving angle of the first blade 231 is, the stronger the shaving ability of the first blade 231 is, ensuring that the coarse hair can be shaved more smoothly.

[0032] Among them, the manual razor provided by the utility model does not reduce the width of the first gap 610 in the vertical direction during the process of adjusting the position of the first base 300 forward and backward, thereby preventing the first gap 610 from being reduced to the point where it cannot accommodate hair scraps, thereby ensuring that the manual razor can always be used normally.

[0033] Among them, during the use of the manual razor provided by the utility model, the blade module 200 can be fixed relative to the handle 100 to ensure that the first blade 231 will not shake relative to the handle 100 during operation, thereby reducing the possibility of the first blade 231 injuring people.

Therefore, when using the manual razor, the user can use the adjustment device 400 to drive the second base 500 to slide forward and backward according to actual needs, thereby adjusting the gap between the rear edge of the second base 500 and the second blade 232, changing the opening size of the gap to meet the use requirements of hair of different thicknesses, and at the same time, the direction of the gap can be changed, that is, the inclination angle of the line between the front edge of the second base 500 and the second blade 232 is adjusted, and then the shaving angle of the second blade 232 to the skin between the front edge of the second base 500 and the second blade 232 is indirectly adjusted to meet the use requirements of skin with different sensitivities. With the above arrangement, the manual razor has double edges, and the gaps corresponding to the double edges can be adjusted as needed.

[0035] Reference Figure 1 and Figure 4According to some embodiments of the utility model, the upper end of the adjustment sleeve 410 is provided with an annular mounting portion 411, the mounting portion 411 is spaced apart from the cutter head module 200, the first base 300 and the second base 500 are both inserted between the cutter head module 200 and the mounting portion 411, wherein the upper surface of the mounting portion 411 is a plane, and the upper surface of the mounting portion 411 is in contact with the first base 300 and the second base 500. With the above arrangement, the first base 300 and the second base 500 can be confined between the mounting portion 411 and the cutter head module 200.

[0036] Reference Figure 3 and Figure 4 According to some embodiments of the utility model, the upper surface of the mounting portion 411 is provided with a first transmission column 412 and a second transmission column 413, the first transmission column 412 and the second transmission column 413 are symmetrically arranged relative to the rotation axis of the adjusting sleeve 410, the first base 300 is provided with a first transmission groove 310 arranged around the rotation axis of the adjusting sleeve 410, the second base 500 is provided with a second transmission groove 510 arranged around the rotation axis of the adjusting sleeve 410, and the inner wall of the first transmission groove 310 is symmetrical to the adjusting sleeve The distance between the rotation axes of the cylinder 410 is gradually reduced in the clockwise direction or counterclockwise direction, the distance between the inner wall of the second transmission groove 510 and the rotation axis of the adjustment sleeve 410 is gradually reduced in the clockwise direction or counterclockwise direction, the first transmission column 412 is abutted against the inner wall of the first transmission groove 310, the second transmission column 413 is abutted against the inner wall of the second transmission groove 510, and the reset structure includes at least two reset springs 420, all of which are connected to the first base 300 and the second base 500. With the above arrangement, when the adjustment sleeve 410 is rotated clockwise (or counterclockwise), the first transmission column 412 can push the first base 300 to move forward, and the second transmission column 413 can push the second base 500 to move backward. When the adjustment sleeve 410 is rotated in the opposite direction, the reset spring 420 can drive the first base 300 to move backward and reset, and the second base 500 to move forward and reset.

[0037] It is conceivable that the above-mentioned reset structure may also be arranged in other ways. For example, the reset structure may include two magnets that cooperate with each other to generate suction, and the two magnets are respectively installed on the first base 300 and the second base 500.

In addition, through the above-mentioned setting, the manual razor can form multiple gears for adjusting the gap, and the gear adjustment is smooth. In the process of the user rotating the adjustment sleeve 410, the first transmission column 412 collides with the first base 300, and the second transmission column 413 collides with the second base 500, which will generate a sound prompting the adjustment of the gap gear.

[0039] It should be noted that, in other embodiments, the adjusting sleeve 410 may also be locked by adjusting the resistance between the sleeve 410 and the handle 100 .

[0040] It is conceivable that the above-mentioned adjustment device 400 can also be set in an actual manner. For example, a gear is set at the upper end of the adjustment sleeve 410, and the first base 300 and the second base 500 are both driven by the meshing of the rack and the gear. Therefore, by rotating the adjustment sleeve 410, the first base 300 and the second base 500 can be driven to slide back and forth. At this time, the above-mentioned reset structure does not need to be set.
