Detailed Description

The technical solutions of the present utility model are explained and illustrated in detail below with reference to the drawings and specific embodiments so that those skilled in the art can better understand the present utility model and implement it. Unless otherwise indicated, structures not refined in the examples are conventional in the art.

Referring to fig. 1-3, a utility art designing knife includes a knife head 100 and a knife handle 200 hinged to each other through a rotation shaft 6, a knife slot 7 is formed on the knife handle 200, and the knife head 100 can be rotatably placed in the knife slot 7 along the rotation shaft 6.

The tool bit 100 comprises a first housing 1, a second housing 2 and a blade 3. The first shell 1 and the second shell 2 are hollow plate-shaped structures so as to reduce the weight of the product.

Referring to fig. 4, the blade 3 includes a first end 31, a middle 32 and a second end 33 integrally formed. The first and second end portions 31, 33 are each acute-angled, and the top end of the middle portion is provided with a plurality of clamping grooves 34 for adapting to the clamping member 4 to fix the blade between the two housings. The clamping member 4 can be inserted into the clamping grooves 34 with different front and rear positions to adjust the protruding distance of the first end 31.

Referring back to fig. 1, the first housing 1 and the second housing 2 are fastened to each other and are fixed by a pin through the through hole 14. The second housing 2 is also provided with through holes at corresponding positions, which are not labeled in the figure. The first housing 1 and the second housing 2 clamp the middle portion 32 and the second end portion 33 of the blade 3, extending only beyond the first end portion 31. The first housing 1 and the second housing 2 are recessed rearward towards the side of the blade first end 31, i.e. the end sides 11, 21. In this embodiment, the rearward recess is curved, which is more attractive while increasing the depth of cut.

In order to prevent the unused portion of the blade 3 from being dulled and also to protect the hands of the user from being scratched, the bottoms of the first and second housings 1 and 2 are respectively provided with a transverse protection plate 23 and a plate groove 13 which are mutually adapted, and the protection plate 23 extends into the plate groove 13 to block the exposure of the blade.

In addition, in order to be convenient for use, the tool bit is pressed with the finger in order to apply force better, and first casing 1 and second casing 2 top integrated into one piece have button 12 and 22, button 12 and button 22 surface are the cockscomb structure in order to increase friction.
