A safety device for an electric pencil sharpener is composed of at least a bracket, a selection turn table, a sliding block, a first switch, and a second switch. After rotating the selection turn table, the sliding block and the first switch are driven to move, such that the second switch is activated to cause a short circuit to the first switch, by a pillar which is formed at a side of the sliding block. The electric pencil sharpener can be only restarted to operate by pressing down manually a press button which is electrically connected with the second switch, so as to reduce danger of cutting a finer when a user puts the finger into a selection hole accidentally.
