Problems solved by technology

And the electric pencil sharpener of prior art can only cut out the tapered pencil nib of a kind of angle, as a last resort, art worker, before work, adopts manual cutting and grinding with the help of utility knife and sandpaper, and prepares many different cones angled conical nib pencil
However, sharpening pencils by hand requires proficient basic pencil sharpening skills, and is inefficient, time-consuming, and labor-intensive.
Therefore, there is a pencil nib that can only be cut into a kind of cone angle in the prior art and cannot meet the needs of art workers.

Abstract

The invention discloses an electric pencil sharpener. The electric pencil sharpener comprises a shell, a driving device is arranged on the bottom of the shell, and a fixing sleeve is arranged on the upper portion of the shell; a hob base is arranged in the fixing sleeve, a tool rest is arranged in the hob base, and a hob is arranged in the tool rest; two or more conical holes with different cone angles are formed in the tool rest in the circumference direction of the hob; a rotary knob is arranged on the shell and is connected with the tool rest, and the rotary knob is rotated to drive the tool rest to rotate so that any conical hole can be coaxially in alignment with a sleeve center hole of the fixing sleeve; the driving device drives the hob base to rotate, the hob base drives the tool rest and the hob to rotate, and the hob drives the fixing sleeve to rotate. The electric pencil sharpener can sharpen pencil tips with different cone angles and can adapt to demands of art designers.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to an electric pencil sharpener. Background technique [0002] The electric pencil sharpener is a common stationery item that can automatically sharpen the tip of a conical pencil. Pencil is an indispensable drawing tool for arts and crafts workers, who need to cut pencils with different lead lengths for sketching, sculpture, and clothing design, that is, need conical pencil nibs with different taper angles. And the electric pencil sharpener of prior art can only cut out the tapered pencil nib of a kind of angle, as a last resort, art worker, before work, adopts manual cutting and grinding with the help of utility knife and sandpaper, and prepares many different cones Angled conical nib pencil. And sharpening pencils by hand requires skilled basic skills of sharpening pencils, and the efficiency is low, and it takes a long time to work hard. Therefore, there is a pencil tip th...
