Problems solved by technology
[0004] The knives of electric pencil sharpeners are divided into two categories: hob assembly or pencil sharpener; the structure of the hob is complicated, and it needs to be equipped with an automatic pen feeding device, so the manufacturing cost is relatively high; such as the electric pencil sharpener of CN206703798U and the electric sharpener of CN201333883Y Pencil, etc.
[0005] The pencil sharpener type electric pencil sharpener has the advantage of lower cost, but the service life of the pencil sharpener is not as good as that of the hob type, so the worn pencil sharpener needs to be replaced frequently
Existing electric pencil sharpeners have the problem that the pencil sharpener is not firmly installed, causing the pencil sharpener to shake and fall off when it is rotating, or there is the problem that the pencil sharpener is inconvenient to disassemble and replace

The invention discloses a pencil sharpener installation structure and an electric pencil sharpener, the pencil sharpener installation structure comprises a pencil sharpener, a movable sleeve and a supporting plate with a pencil inserting hole, the pencil sharpener comprises a knife rest and a blade, an elastic piece is arranged between the movable sleeve and the supporting plate, the bottom end of the knife rest is provided with a connector detachably connected with a driving assembly, and the pencil inlet end of the knife rest is connected with the movable sleeve in a sleeved mode; a center hole of the movable sleeve is in butt joint with the pen inserting hole and a pen inlet hole of the knife rest, the movable sleeve moves towards the supporting plate and compresses the elastic piece, and therefore the pen inlet end of the knife rest can be separated from the movable sleeve. The pencil sharpener is convenient to replace, and stress points are arranged at the two ends of the pencil sharpener, so that the stability of the pencil sharpener is better during rotation.
Description
technical field [0001] The invention relates to a pencil sharpener for cutting pencils, in particular to a pencil sharpener installation structure of an electric pencil sharpener. Background technique [0002] A pencil sharpener is a study or office supply. Early pencil sharpeners included a frame with an obliquely positioned blade into which a pencil was inserted, and the pencil was cut by turning the sharpener. [0003] Now it is more common to use pencil sharpeners, which can be classified into hand-operated pencil sharpeners and electric pencil sharpeners based on the power of driving the pencil sharpening mechanism. [0004] The knives of the electric pencil sharpener are divided into two categories: the hob assembly or the pencil sharpener; the hob has a complex structure and needs to be equipped with an automatic pen feeding device, and the manufacturing cost is high; such as the electric pencil sharpener of CN206703798U and the electric sharpener of CN201333883Y Pe...
