[0025] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5 As shown, the utility model discloses a blade assembly of a razor, comprising a base body 1, to which a blade 2 is connected, and an elastic bracket 3 for supporting the blade head is also provided in the base body 1, the elastic bracket 3 is connected to a limit knob 4 which can limit the relative movement of the elastic bracket 3 and the base body 1 after rotation or release the relative movement restriction between the elastic bracket 3 and the base body 1, the limit knob 4 comprises a knob body 41, the knob body 41 is provided with a buckle portion 42 which can be buckled and connected with the elastic bracket 3, the elastic bracket 3 is provided with a socket 31 for the buckle portion 42 to be inserted and rotated, the knob body 41 is also provided with a limit portion 43, the elastic bracket 3 is provided with a limit groove 32 which can cooperate with the limit portion 43 to limit the rotation range of the limit knob 4, and the limit knob 4 is connected with a magnetic suction piece 5.

[0027] The base body 1 can provide support for other components, and a cutter head 2 is connected to the base body 1 to achieve a shaving function. The elastic bracket 3 supports the cutter head 2 and provides the necessary elasticity for the cutter head 2, so that the cutter head 2 can fit the facial contour and improve the uniformity and comfort of shaving. The relative movement of the elastic bracket 3 and the base body 1 is adjusted by the limit knob 4. When the user needs to remove the cutter head 2, the limit knob 4 can be rotated to release the limit of the relative movement between the elastic bracket 3 and the base body 1, so as to remove the elastic bracket 3, and then remove the cutter head 2 for cleaning and replacement. After completion, the user connects the cutter head 2 to the base body 1, installs the elastic bracket 3 into the base body 1, and limits the relative movement between the elastic bracket 3 and the base body 1 by rotating the limit knob 4, so as to restore the cutter head assembly to a normal use state. The mechanical connection between the limit knob 4 and the elastic bracket 3 is achieved by the setting of the buckle portion 42 and the socket 31. The setting of the limiting part 43 and the limiting groove 32 limits the rotation range of the knob 4 to avoid damage caused by excessive rotation. The setting of the limiting knob 4 connected with the magnetic attraction part 5 enables the blade head assembly to be magnetically connected to the razor blade body, which is convenient to use.

[0028] By setting the limit knob 4 which can limit the relative movement between the elastic bracket 3 and the seat body 1 after rotation, the user can disassemble and reassemble the cutter head 2 by rotating the limit knob 4, which is convenient for cleaning and replacing the cutter head 2. The maintenance difficulty of the user is reduced, and the usability and maintenance efficiency of the cutter head assembly are improved.

[0029] In the embodiment, the buckle portion 42 specifically includes a main rod, and one end of the main rod is provided with a convex buckle protruding outward in a claw-like structure. Through the arrangement of the limit portion 43 and the limit groove 32, the buckle portion 42 can avoid being subjected to longitudinal stress while being subjected to lateral stress caused by excessive rotation of the limit knob 4 or improper operation, thereby extending the service life of the buckle portion 42.

[0030] By providing the magnetic element 5, the cutter head assembly can be magnetically connected to the shaver body, which simplifies the process of replacing the cutter head and improves the convenience of use.

[0031] The limiting groove 32 includes a first limiting groove 321 and second limiting grooves 322 disposed at both ends of the first limiting groove 321 and connected to the first limiting groove 321 . A first limiting block 323 is disposed on the inner side wall of the first limiting groove 321 .

[0032] By providing the second limiting grooves 322 connected to the first limiting grooves 321 at both ends thereof, when the limiting knob is rotated to the limit position, the limiting portion 43 enters the second limiting groove 322 from the first limiting groove 321. By providing the first limiting block 323, the limiting portion 43 in the second limiting groove 322 is ensured to be firmly positioned to prevent accidental sliding.

[0033] The socket 31 includes a rotating groove 311, which has a locking section 3111 that can accommodate the buckle part 42 when the limit knob 4 limits the relative movement between the elastic bracket 3 and the seat body 1, and an unlocking section 3112 that can accommodate the buckle part 42 when the limit knob 4 releases the relative movement restriction between the elastic bracket 3 and the seat body 1. The locking section 3111 is provided with a notch 312 for the buckle part 42 to be inserted or removed.

[0034] By providing a notch 312 on the locking section 3111 for the buckle portion 42 to be inserted into or out of, when the user removes the limit knob 4 from the elastic bracket 3, it is necessary to first rotate the limit knob 4 so that the buckle portion 42 is in the unlocking section 3112, and after removing the elastic bracket 3 and the limit knob 4 buckled with the elastic bracket 3 from the base body 1, rotate the limit knob 4 in the opposite direction so that the buckle portion 42 is in the locking section 3111 and opposite to the notch 312, and finally remove the buckle portion 42 from the notch 312, thereby separating the limit knob 4 from the elastic bracket 3, so that the user needs to rotate the limit knob 4 twice to remove the limit knob 4 from the tool head assembly, thereby reducing misoperation.

[0035] The cutter head 2 includes a fixed knife 21 and a movable knife 22 arranged below the fixed knife 21. The elastic bracket 3 includes a bracket body 33 and a protrusion 34 arranged on the outer wall of the bracket body 33. The left and right side walls of the protrusion 34 are provided with elastic arms 35 that can be deformed and bent downward when subjected to pressure and elastically return to their original position when the pressure disappears. The elastic arms 35 abut against the lower part of the fixed knife 21.

[0036] The fixed blade 21 serves as a stable cutting surface during shaving, and cooperates with the movable blade 22 to achieve cutting. The elastic bracket 3 transmits appropriate elastic force through the elastic arm 35 to ensure that the blade head 2 has sufficient pressure when in contact with the skin, thereby improving the fit and comfort of shaving. By arranging the elastic arms 35 on the left and right side walls of the protrusion 34, compared with arranging the elastic arms 35 on only one side, it can ensure that the blade head 2 is subjected to more balanced forces in different directions, which helps the blade head 2 to fit the skin more stably and reduce vibration and discomfort during shaving.

[0037] The protrusion 34 is also provided with a second limiting block 36 for limiting the fixed knife 21 from escaping upward.

[0038] The second limiting block 36 ensures that the cutter head assembly remains intact during the shaving process and the fixed cutter 21 will not fall off due to strong pressure or accidental falling, thereby improving the safety and reliability of use.

[0039] The knob body 41 has an installation slot 411 at its upper portion, and the magnetic attraction member 5 is disposed in the installation slot 411 .

[0040] Compared with setting the mounting groove 411 at the lower part of the knob body 41, the mounting groove 411 at the upper part of the knob body 41 can make the magnetic member 5 more firmly fixed inside the limit knob 4. By setting the mounting groove 411, the internal space is fully utilized without hindering the normal rotation operation of the knob.

[0041] The groove wall of the installation groove 411 is provided with a limiting rib 412 for limiting the magnetic attraction member 5 from falling out.

[0042] By setting the limiting rib 412, the range of movement of the magnetic component 5 in the installation groove 411 is limited to prevent it from accidentally falling out due to vibration, external impact or improper operation during use, thereby reducing the degradation of shaving experience or component damage caused by the movement of the magnetic component 5, and improving the durability and reliability of the product.

[0043] The knob body 41 is provided with a limiting arm 44 , and the inner wall of the seat body 1 is provided with a third limiting block 11 which can abut against the limiting arm 44 to limit the limiting knob 4 from moving downward.

[0044] By setting the limiting arm 44 and the third limiting block 11, the limiting knob 4 is limited from moving downward, thereby completing the limitation of the relative movement between the elastic bracket and the seat body.

[0045] The inner wall of the seat body 1 is provided with a guide column 12 , and the elastic bracket 3 is provided with a guide groove 37 that can cooperate with the guide column 12 .

[0046] The provision of the guide column 12 and the guide groove 37 ensures accurate positioning of the elastic bracket 3 when it is installed inside the seat body 1, thereby avoiding misalignment or tilting during installation.

[0047] The elastic support 3 is provided with an insertion hole 38 , and the seat body 1 is provided with an insertion column 13 capable of matching with the insertion hole 38 .

[0048] The arrangement of the insertion hole 38 and the insertion column 13 further provides fixation between the elastic bracket 3 and the seat body 1 .
