[0022] Reference Figure 1-Figure 3 The utility model provides an embodiment: a soap head skin preparation knife, comprising a base 1, the upper end surface of the base 1 is fixedly connected to the holding rod 2, the bottom end surface of the base 1 is rotatably connected to the first rotating wheel 17, the first rotating wheel 17 is fixedly connected to the first rotating shaft 13 on the end surface close to the base 1, the first rotating shaft 13 penetrates the end surface of the base 1 and extends to the upper part of the base 1 and is fixedly connected to the threaded rod 14, the threaded rod (14) is fixedly connected to the end surface away from the base 1. The limit plate 24 prevents the lifting rod 3 from excessively rising and prevents the lifting rod 3 from falling off, the lower part of the inner outer wall of the holding rod 2 is fixedly connected to the second fixing plate 16, the threaded rod 14 is rotatably connected to the second fixing plate 16, and the second fixing plate 16 is again provided for the threaded rod 14 The lifting rod 3 is fixedly connected to the upper part of the outer wall of the lifting rod 3 and the limiting ring 12 is fixedly connected to the inner outer wall of the holding rod 2. This arrangement is to prevent the lifting rod 3 from deviating during movement. The lifting rod 3 is fixedly connected to the first fixed plate 4 at one end surface away from the base 1. A blade 6 is arranged above the first fixed plate 4. A knife cover 5 is arranged above the blade 6. The end surface of the knife cover 5 away from the blade 6 is fixedly connected to the mounting frame 8. A moving component is arranged inside the mounting frame 8.

[0023] Specifically, the first rotating wheel 17 controls the rotation of the threaded rod 14 by driving the first rotating shaft 13, so that the connecting plate 15 can move up and down, so the lifting rod 3 can be raised and lowered, thereby changing the position of the blade 6, allowing the user to more flexibly control the position of the blade 6 and facilitate skin preparation operations at various angles and depths.

[0024] The moving assembly includes a bidirectional screw 19, a slide plate 20 and a limiting groove 21. One side end surface of the mounting frame 8 is rotatably connected to the second rotating wheel 22. The second rotating wheel 22 is fixedly connected to the second rotating shaft 18 near one end surface of the mounting frame 8. The second rotating shaft 18 passes through one end surface of the mounting frame 8 and extends to the inside of the mounting frame 8 and is fixedly connected to the bidirectional screw 19. The outer wall of the bidirectional screw 19 is connected to two slide plates 20 by threads. The insides of the two slide plates 20 are provided with threads in opposite directions. The two slide plates 20 are symmetrically arranged along the center line of the bidirectional screw 19. One end surface of the slide plate 20 is fixedly connected to the clamping plate 11. The clamping plate 11 is slidably connected to the end surface of the mounting frame 8 near the mounting groove 23. This arrangement is to prevent the clamping plate 11 from offsetting during movement. A mounting groove 23 is provided on one end surface of the mounting frame 8. Two limiting grooves 21 are provided on one end surface of the mounting frame 8 near the mounting groove 23. The limiting groove 21 can limit the sliding distance of the slide plate 20, thereby limiting the movement of the clamping plate 11. A liquid storage box 9 is provided on one end surface of the mounting frame 8 near the mounting groove 23.

[0025] Specifically, the second rotating wheel 22 controls the rotation of the bidirectional screw 19 by driving the second rotating shaft 18, so that the two slide plates 20 move toward or away from each other, and the two clamping plates 11 move toward or away from each other, so as to install or remove the liquid storage box 9.

[0026] A pressing pump 10 is installed on the surface of one end of the liquid storage box 9 away from the mounting frame 8 , and a liquid guide tube is installed at the bottom of the pressing pump 10 .

[0027] Specifically, soap liquid is stored in the liquid storage box 9 to soften the hair on the skin preparation area or the surgical area. A piston, a spring, and a valve (a round plastic ball) are provided inside the pressing pump 10. The movement of the piston in the pressing pump 10 is utilized to discharge the air in the liquid storage box 9, thereby causing an air pressure difference between the inside and the outside, so that the soap liquid rises under the action of the air pressure and is discharged from the liquid guide tube to the outside of the tube.

[0028] Comb teeth 7 are provided on both side end surfaces of the first fixing plate 4 , and the comb teeth 7 are symmetrically arranged.

[0029] Specifically, the arrangement of the comb teeth 7 prevents the blade from being directed at the skin, and the comb teeth 7 can straighten out long and curly hair.

[0030] Working principle: Place the liquid storage box 9 on one end surface of the mounting frame 8 close to the mounting groove 23, rotate the second rotating wheel 22, the second rotating wheel 22 can indirectly control the rotation of the bidirectional screw 19, so that the two slides 20 move toward each other, so the two clamping plates 11 can fix the liquid storage box 9 for installation of the liquid storage box 9, and vice versa for removal; rotate the first rotating wheel 17, the first rotating wheel 17 can indirectly rotate the threaded rod 14, so that the connecting plate 15 moves, because the connecting plate 15 is connected to the lifting rod 3, the lifting rod 3 can extend or retract, thereby changing the position of the blade 6.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
