Abstract
The invention discloses a pencil sharpening mechanism and pencil sharpener for cutting a sketch pencil. The pencil sharpening mechanism comprises a knife rest, a rotating wheel seat and a hob. The hob is mounted on the knife rest. A gear at one end of the hob is engaged with an inner gear on the rotating wheel seat. A pencil inserting channel is arranged on the knife rest. An included angle is formed between the center axis of the hob and the center axis of the pencil inserting channel. The hob comprises a front segment part and a rear segment part which are arranged integrally. The rear segment part is cylindrical and is used for cutting a wood part of the sketch pencil. The front segment part is in a frustum shape with the diameters gradually decreased from back to front. The cutting line, close to the pencil inserting channel, of the front segment part is basically parallel to the center axis of the pencil inserting channel. The pencil sharpening mechanism has the beneficial effects that when the sketch pencil is inserted into the pencil inserting channel, the hob rotates, the rear segment part of the hob cuts the wood part of the sketch pencil, and the wood conical part is obtained through cutting; and along with propulsion of the sketch pencil, the front segment part of the hob cuts residual wood adhering to the surface of a carbon core, and therefore the purity of the carbon core is guaranteed, and the original cylindrical shape of the carbon core is kept.

Specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in figures 3 to 6, cut the penknife structure of sketch pencil, including knife rest 1, rotaring wheeling base 2 and hobboing cutter 3, hobboing cutter 3 is pacified
It is contained on knife rest 1, the gear 4 of hobboing cutter 3 one end is engaged with the internal gear 5 on rotaring wheeling base 2, knife rest 1 is provided with and inserts a passage 6,
The central axis 31 of hobboing cutter 3 is in an angle a with the central axis 61 inserting a passage 6, and hobboing cutter 3 includes the front section being wholely set
32 and hindfoot portion 33, hindfoot portion 33 is in column type and the woody part for cutting sketch pencil 7, front section 32 be in by
Near the line of cut 321 inserting a passage 6 and a slotting passage 6 on the taper type that diameter tapers into forward afterwards, and front section 32
Central axis 61 substantially parallel.As shown in figure 5, taper according to needed for pencil cutting woody part for the size of this angle a is big
Little decision.The line of cut 321 of front section 32 substantially parallel with the central axis 61 inserting a passage 6 so that pencil cutting carbon core
In column type, the carbon core meeting sketch pencil requires.
Front section 32 is near line of cut 321 being equal to apart from r1 to the central axis 61 inserting a passage 6 inserting a passage 6
Or be slightly less than the radius r2 of the carbon core 71 of sketch pencil 7, as shown in fig. 7, when apart from ri equal with radius r2 when, hobboing cutter 3
The carbon core 71 of sketch pencil 7 is not cut, the hindfoot portion 33 of hobboing cutter 3 all cuts to 7 woody parts of sketch pencil
Fall.When being slightly less than radius r2 apart from ri, the woody part that the front section 32 of hobboing cutter 3 remains to sketch pencil 7 is cut,
Or front section 32 slightly cuts to the carbon core 71 of sketch pencil 7, and make the carbon core 71 of sketch pencil 7 in original circle
Column type.
Knife rest 1 includes first end 11 and the second end 12, and rotaring wheeling base 2 is provided centrally with through hole 21, first end 11
It is placed in through hole 21, the second end 12 is provided with and inserts the carbon core passage 62 that a passage 6 connects, and first end 11 is provided with slotting
Entrance 111.Sketch pencil 7 to be cut inserts from rotaring wheeling base 2 direction, that is, inserts at inserting an entrance 111.Sketch pencil
Cutting carbon core out extend in the carbon core passage of knife rest the second end so that carbon core can extend to more than 30 millimeters, and
Will not be stopped.
The fast button push 10 for releasing disconnected core of be aligned carbon core passage 62 is provided with the second end 12.When sketch pencil
Carbon core fracture when, press inward against fast button push 10 it is possible to release disconnected core in carbon core passage 62.Therefore disconnected core will not fall
Fall in rotaring wheeling base, between fast button push 10 and knife rest 1, be provided with back-moving spring 101, when there is no outer active force pressing, reset
Spring recovers in situ.
