DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a dermatological scraper convenient for cleaning dandruff, comprising a handle 1, first protrusions 2 are symmetrically fixedly installed on both sides of one end of the handle 1, and two groups of opposite first protrusions 2 are rotatably installed on the surface of the handle 2, because the extended handle 3 is provided, the two groups of extended handles 3 are controlled to be closed and connected at one end of the handle 1, thereby increasing the hand-held length of the handle 1;

[0021] The second protrusions 4 are fixedly mounted on both sides of the extended handle 3 at the top of one end of the knife handle 1 at one end away from the first protrusion 2, and a rotating clamping plate 5 is rotatably mounted on the surface of the second protrusion 4. The end of the extended handle 3 at the bottom of one end of the knife handle 1 away from the first protrusion 2 is fixedly mounted with a clamping protrusion 6, and the clamping protrusion 6 corresponds to the rotating clamping plate 5. By providing the rotating clamping plate 5 and the clamping protrusion 6, after the two sets of extended handles 3 are in contact and closed, the rotating clamping plate 5 is controlled to rotate and clamp on the surface of the corresponding clamping protrusion 6, so that the two sets of extended handles 3 are connected and closed and will not be separated at will.

[0022] The end of the knife handle 1 away from the first protrusion 2 is fixedly installed with a mounting tool holder 7, and the two sides of the mounting tool holder 7 close to the end of the knife handle 1 are symmetrically fixedly installed with third protrusions 8, and the surfaces of the two groups of third protrusions 8 are rotatably installed with fixing frames 9. Because the fixing frames 9 are provided, after the knife seat 13 is inserted into the mounting tool holder 7, the fixing frames 9 are rotated to clamp one side of the knife seat 13, so that the knife seat 13 can be clamped in the mounting tool holder 7, which is convenient for disassembly or installation of the knife seat 13;

[0023] A rubber clamping block 10 is fixedly installed at one end of both sides of the mounting tool holder 7 away from the third protrusion 8, and the rubber clamping block 10 corresponds to the fixing frame 9. By providing the rubber clamping block 10, the rubber clamping block 10 is squeezed and deformed between the mounting tool holder 7 and the fixing frame 9, so as to clamp and fix the fixing frame 9;

[0024] Pads 11 are fixedly installed at the bottom of the third protrusion 8 and the rubber clamp 10 on both sides of the installed tool holder 7, and three groups of limit clamping strips 12 are symmetrically fixedly installed on both sides of the inner wall of the installed tool holder 7. Because of the pads 11, when the rotating fixed frame 9 is clamped on the installed tool holder 7 to clamp and fix the tool seat 13, the bottom of the fixed frame 9 is placed on the top of the pad 11 to ensure that the fixed frame 9 is clamped on the surface of the rubber clamp 10 and will not fall.

[0025] A knife seat 13 is installed inside the knife holder 7, and multiple groups of positioning posts 1301 are evenly fixedly installed inside the knife seat 13. Three groups of first slots 1302 are equidistantly provided on both sides of the knife seat 13, and the first slots 1302 correspond to the limiting card strips 12.
