Abstract
The utility model discloses a pencil sharpener with double cutters. The pencil sharpener device with the double cutters comprises cutter rests and sharpening mechanisms. A sharpening cavity is arranged on the cutter rests, wherein a pencil-shaped object can be inserted into the sharpening cavity. Each sharpening mechanism comprises at least two sets of cutter shafts and a hobbing cutter. The hobbing cutter is arranged on each cutter rest through the cutter shafts in an inclining mode and is inserted into the sharpening cavity to sharpen the pencil-shaped object. Each sharpening mechanism is further connected with a stopping mechanism which is capable of automatically controlling each sharpening mechanism to stop working. According to the pencil sharpener with double cutters, the stopping mechanism which is capable of automatically controlling the sharpening mechanisms to stop working is added to a traditional pencil sharpener with double cutters. When the pencil-shaped object is inserted into the sharpening cavity to a presupposed degree, the end portion of the pencil-shaped object abuts against a contact block and then a contact rod is driven to contact a switch device. Power supply of the sharpening mechanism is cut off. The excessive sharpening or the insufficient sharpening of the pencil-shaped object is avoided. The contact block can return to the original position by using the elasticity of a spring on the contact rod or the return elasticity of the switch device. Proceeding of a subsequent sharpening operation is guaranteed.
