The number of holding claws 104 is plural, and the holding claws 104 are uniformly distributed along the circumferential direction of the end face of the first impeller 102. The number of holding claws 104 corresponds to the number of sides of the cross section, and each holding claw 104 is held on the side of the corresponding first impeller shaft 101. In this embodiment, the number of the holding claws 104 is four, and the cross section is a regular quadrangle corresponding to the number of the holding claws.
The turbine 3 comprises a body 301, and a plurality of arc racks 302 distributed in a turbine shape are arranged on the upper surface of the body 301. The inner end of the arc-shaped rack 302 is positioned at the inner side of the previous arc-shaped rack 302, and the outer end of the arc-shaped rack 302 is positioned at the outer side of the next arc-shaped rack 302. The height of the curved rack 302 increases gradually from the inner end to the outer end of the curved rack 302. The inner end of the arc-shaped rack 302 is provided with a guide surface 303.
The automatic pencil feeding mechanism for the pencil sharpener further comprises a mounting seat 4 and an upper cover 5, wherein a pencil feeding hole 501 is formed in the upper cover 5, and the upper cover 5 is connected with the mounting seat 4. The first pen feeding assembly 1, the second pen feeding assembly 2 and the turbine 3 are all arranged in a cavity formed by the mounting seat 4 and the upper cover 5. The two sides of the upper port of the mounting seat 4 are respectively provided with a mounting groove 401 for mounting the first impeller shaft 101 and the second impeller shaft 201, and the two ends of the first impeller shaft 101 and the two ends of the second impeller shaft 201 are respectively mounted in the mounting grooves 401 on the two sides of the corresponding mounting seat 4.

The automatic pencil feeding mechanism for pencil sharpener of the present invention has the following working principle: when a pen is fed into the pen cutter, the worm wheel rotates anticlockwise in the vertical direction under the driving of the worm cutter hob, the worm wheel meshing surface A generates a anticlockwise force which deviates to the circle center direction, and the force acts on the meshing surface A of the first impeller 102 to push the first impeller 102 to rotate anticlockwise in the horizontal direction; the second impeller 202 rotates clockwise in the horizontal direction due to the opposite direction. The first impeller 102 and the second impeller 202 drive the two pen feeding rubber rollers to rotate inwards in the horizontal direction, and the pen feeding rubber rollers generate downward force in the vertical direction, so that automatic pen feeding is realized. When the pen is withdrawn, the hob rotates clockwise, the turbine kneading surface B pushes the first impeller 102 to knead the surface B, the first impeller 102 rotates anticlockwise in the horizontal direction, the second impeller 202 rotates clockwise in the horizontal direction, the first impeller 102 and the second impeller 202 drive the two pen feeding glue rollers to rotate outwards in the horizontal direction, and the pen feeding glue rollers generate a force upwards in the vertical direction, so that automatic pen withdrawal is realized.
Compared with the bevel gear and crown gear meshing mechanisms, the two meshing mechanisms can only change the rotation motion of the rotating shaft to 90 degrees with the original shaft, and cannot deviate from a certain position. Compared with a pencil sharpener, the pencil sharpener has no pencil feeding space, and driving mechanisms such as gears and the like are additionally used for realizing automatic pencil feeding. The turbine impeller meshing mechanism can directly twist the rotary motion of the hob by 90 degrees in the motion direction, and rotates at a certain distance from the rotary center of the hob driving the turbine, and then the impeller drives the rubber roll on the impeller shaft to rotate, and the rubber roll clamps the pencil to rotate, so that automatic pencil feeding is realized. Compared with other transmission mechanisms, the turbine impeller mechanism has the advantages of compact structure, reliable operation, stable transmission, high efficiency, long service life, small noise and capability of ensuring constant transmission ratio.
The clutch is arranged between the first impeller 102 and the first impeller shaft 101 of the automatic pencil sharpener, so that a large rotating force is generated when sharpening pencil (the force drives the pencil to rotate), the clutch is separated, the first pencil feeding rubber roller 103 is driven to rotate only by the force of the first impeller 102, the pencil is driven to feed by extrusion, and the second pencil feeding rubber roller 203 on the second impeller shaft 201 does not rotate at the moment. When the pencil is fed and withdrawn (the pencil is not cut), the clutch is closed because of no great rotating force, and the first pencil feeding component 1 and the second pencil feeding component 2 drive the pencil to rapidly feed and withdraw. The pencil sharpener has the advantages of compact structure, reliable operation, stable transmission, high efficiency, long service life, small noise and capability of ensuring that the pencil is not rotated in the pencil sharpening process.
