Abstract

A safety device for an electric pencil sharpener (30) comprises a bracket (401), a selection turn table (402), a sliding block (403), a first switch (404), and a second switch (405), wherein after the selection turn table (408) is rotated, the sliding block (403) and the first switch (404) are driven to move, such that the second switch (405) is activated to cause a short circuit to the first switch (404), by a pillar (4031) which is formed at a side of the sliding block (403). The electric pencil sharpener (30) can be only restarted to operate by pressing down manually a press button (4051) which is electrically connected with the second switch (405), so as to reduce danger of cutting a finger when a user puts the finger into a selection hole (4021) accidentally.
