Abstract

The utility model discloses an art knife, which relates to the field of cutters and comprises a cutter head, a cutter handle and a rotating shaft, wherein the cutter handle comprises a plastic part A and a plastic part B which are fixedly connected, and an arc-shaped bulge is arranged at the joint of the plastic part B and the plastic part A and wraps the edge of the plastic part A, so that the end part of the plastic part B is slightly higher than the plastic part A; the cutter head is rotatably connected with the plastic part A through a rotating shaft, so that the cutter head can be accommodated in the cutter handle. The utility model has the advantages that: the soft plastic handle part and the arc-shaped bulge are adopted, so that the rotation of the knife handle and the knife head is effectively avoided; the back of the knife handle is provided with a structure similar to a fish back, so that the utility knife is prevented from being vertically arranged on a table top.

Description

Art designing knife

Technical Field

The utility model relates to a field of cutter, concretely relates to art knife.

Background

The art designing knife is also commonly called as a graver or a wallpaper knife, is a knife for art and handicraft, is used for cutting objects with soft texture, comprises a knife handle and a blade, and is usually in a drawing structure.

Of course, some art designing knives with a rotary structure are available, but the knife handle and the knife head of the rotary art designing knife are easy to rotate around the table top when not in use (usually placed on the table top), so that potential safety hazards exist. In addition, if the user improperly places after using, the existing rotary type art designing knife is easy to be formed under the condition that the back of the knife handle leans against a table top, and the knife head faces upwards and is placed on the table, so that the safety of the user is seriously threatened.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art, and provides an art knife which has the advantages of simple structure and safe use.

The purpose of the utility model is accomplished through following technical scheme: the utility knife comprises a knife head, a knife handle and a rotating shaft, wherein the knife handle comprises a plastic part A and a plastic part B which are fixedly connected, an arc-shaped bulge is arranged at the joint of the plastic part B and the plastic part A, and the edge of the plastic part A is wrapped by the arc-shaped bulge, so that the end part of the plastic part B is slightly higher than the plastic part A; the cutter head is connected with the plastic part A through a rotating shaft.

As a further technical scheme, the arc-shaped protrusion is arranged at the gravity center of the cutter head and the cutter handle along the length direction.

As a further technical scheme, the back of the plastic part B is provided with a fish-back-shaped bulge.

In a further aspect, the plastic part a is preferably made of a hard plastic, and the plastic part B is preferably made of a soft plastic.

The utility model has the advantages that: the soft plastic handle part and the arc-shaped bulge are adopted, so that the rotation of the knife handle and the knife head is effectively avoided; the back of the knife handle is provided with a structure similar to a fish back, so that the utility knife is prevented from being vertically arranged on a table top.

Description of reference numerals: the knife comprises a knife head 1, a knife handle 2, a plastic part A2-1, a plastic part B2-2, an arc-shaped bulge 2-3, a fish back-shaped bulge 2-4 and a rotating shaft 3.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in the attached figure 1, the utility knife comprises a knife head 1, a knife handle 2 and a rotating shaft 3, wherein as shown in figure 2, the knife handle 2 comprises a plastic part A2-1 and a plastic part B2-2 which are fixedly connected through threads, wherein the plastic part A2-1 is made of hard plastics, and the plastic part B2-2 is made of soft plastics. An arc-shaped bulge 2-3 is arranged at the joint of the plastic part B2-2 and the plastic part A2-1, the arc-shaped bulge 2-3 wraps the edge of the plastic part A2-1, and the end part of the plastic part B2-2 is slightly higher than the plastic part A2-1. Meanwhile, the arc-shaped protrusion 2-3 is arranged at the gravity center of the tool bit 1 and the tool shank 2 along the length direction. The tool bit 1 is rotatably connected with the plastic part A2-1 through the rotating shaft 3, so that the tool bit 1 can be accommodated in the tool handle 2.

The utility model redesigns the structure of the utility knife, and the knife handle 2 is formed by connecting and fixing the plastic part A2-1 and the plastic part B2-2 through threads. Considering that the surface of the hard plastic is smooth and easy to rotate on a table, an arc-shaped bulge 2-3 is arranged at the connecting end part of the plastic part B2-2 and used for wrapping the edge of the plastic part A2-1, thereby preventing the knife handle 2 from rotating. As shown in figure 3, the back of the plastic part B2-2 is designed with a fish-back-shaped bulge 2-4, so that the contact area between the back of the knife handle 2 and the table top is small when the back is vertically arranged, the knife handle can incline, the back cannot be stably vertically arranged, and the back can only be kept horizontal with the table top. Thereby guarantee that the user uses the back, tool bit 1 can not place up, avoids causing the threat to the user.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
