Problems solved by technology

", the pencil sharpener is realized by two large and small hobs, although different nibs can be cut by adjusting the small hob, but due to the problem of eccentricity and the problem that the sun gear needs to slide, the knife The vibration of the frame and the hob is relatively large. The sketch pen is different from the ordinary writing pencil. It needs to expose a long lead, so there is still the problem of easy broken core, and the two hobs are prone to appear due to the difference in size when cutting. Interference caused by broken core
Therefore, the prior art pencil sharpener saves and cuts the problem that the sketch pen success rate is low

Abstract

A sharpener for sketch pencils comprises a knife rest (2) rotationally connected in a shell (1), and an upper seat (3) connected in the shell (1). The upper seat (3) is located above the knife rest (2), a knife driving gear (4) is arranged at the upper end of the knife rest (2), and a knife (5) is rotationally connected to one side of the knife rest (2) and is in transmission connection with the knife driving gear (4). The knife rest (2) is provided with a conical pencil sharpening hole (21), a pencil sharpening opening (22) is formed in the part, near the knife (5), of the inner wall of the pencil sharpening hole (21), an included angle ranging from 2 degrees to 8 degrees is formed between the axis of the knife (5) and the axis of the pencil sharpening hole (21), the length of the knife (5) ranges from 35 mm to 45 mm, and the knife (5) is a hob. Compared with the prior art, the sharpener for sketch pencils has the advantages of being low in cost, small in vibration, capable of sharpening sketch pencils, good in sharpening stability and high in sharpening success rate.

Description
