Abstract
The utility model discloses an electric pencil sharpener with an improved hob safety structure. A stop piece and a time relay switch are arranged in a shell, wherein the time delay switch is connected to a main circuit to play a role in delayed outage, the stop piece is matched with the time delay switch in a triggering mode. A section of time delay contact plate is arranged on a hob frame in the rotating direction. After a trigger switch is turned off, the time delay contact plate abuts against and ejects the stop piece, the stop piece triggers the time delay switch, the main circuit is then powered on, and the hob frame continues to rotate; when the trigger switch is turned off and the stop piece resets after the time delay contact plate is separated from the stop piece, the hob frame continues to rotate under the inertia effect till the time delay contact plate collides with the stop piece, the stop piece stops the time delay contact plate, and the hob frame stops in the position, facing towards the inner side, of a hob. The electric pencil sharpener is simple in structure, it is ensured that the hob faces towards the inner side after a pencil is sharpened and taken out each time, and therefore the hob faces towards the inner side of the machine after a trash box is taken out, it is ensured that the hob can not scratch a user, and potential safety hazards of the electric pencil sharpener are eliminated.
