Abstract:
Disclosed is a hand-crank pencil sharpener, comprising a housing and a gearing member and a sharpening member which are installed within the housing. The gearing member is connected to a hand crank and transmits a rotation of the crank to the sharpening member. A vertical feeding path is provided for a pencil to be inserted into the sharpening member. The hand-crank pencil sharpener further comprises a feeding member in the feeding path. The gearing member comprises a gearing branch for driving the feeding member. The inserted pencil is fed into or withdrawn from the sharpener automatically by a linkage of the gearing branch and the feeding member when the crank is rotated clockwise or counterclockwise.
