Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Fig. 1~7, a kind of pen core thickness regulating mechanism of pencil sharpener, including knife rest 1,2, push rod 4 of shaking the hand, adjusting
Bar 3 and gear ring 6, knife rest 1 be mounted on shake the hand 2 front end, be fixed on pencil sharpener casing by gear ring 6, adjusting rod 3 and push rod 4
It can be co-axially located at and be shaken the hand in 2 movably forward and backward, the front end of adjusting rod 3 is protruded into knife rest 1 and protrudes into knife rest taper to limit pen tip
Cut the depth of a chamber, push rod 4 can limit to front and back moving in rotation be set in shake the hand 2 rear portion, the front end of push rod 4 and adjusting rod 3
Rear end offset, outer is formationed rotating part 43 of shaking the hand is stretched out in the rear end of push rod 4, is realized by the rotation of push rod 4 to 3 axial direction of adjusting rod
The adjusting of shift motion；It shakes the hand and axially offers a through hole placed for adjusting rod 3, push rod 4 in 2, before through hole is divided into
Two sections afterwards, wherein leading portion is expanding internal thread hole, and the rear end of knife rest 1 forms corresponding external screw thread linkage section 11, and knife rest 1 is logical
Cross be threadedly coupled be mounted on shake the hand 2 front end, be fixed on pencil sharpener casing by gear ring 6, the back segment of through hole is hexagon ring,
Connector of the hexagonal swivel nut 5 cooperated with push rod 4 as limitation rotation is embedded in hexagon ring, it is of course possible to not use hexagonal spiral shell
Set, can also be using the connector sleeve that guiding rib is distributed with outside circumference, and principle is similar；The leading portion of push rod 4 is external thread section 42,
The internal thread segment 51 cooperated with the external thread section 42 of push rod 4 is equipped in hexagonal swivel nut 5, push rod 4 passes through the screw thread with hexagonal screw rod 5
Cooperation can be arranged in movably forward and backward shakes the hand in 2, the front end of hexagonal swivel nut 5 be equipped with shake the hand 2 through hole in step surface phase
The annular convex edge 52 supported, the front end of push rod 4 are recessed with the annular slot 41 being placed in for circlip 7, when push rod 4 is moved forward and backward, card
Spring 7 plays the role of limit, anti-throw-out lever abjection；Adjusting rod 3 is equipped with the button bit matched with knife rest, so that shake the hand 2 and knife
When frame separates, adjusting rod 3 will not fall off, the ball that the rear end of adjusting rod 3 is convexly equipped with annular retaining ring 32 and offsets with push rod 4
Face protrusion 31, wherein annular retaining ring 32 offsets with the rear end of knife rest 1 when adjusting rod 3 moves forward and plays position-limiting action, in adjusting rod 3
On be arranged with a spring 8, spring 8 is supported between the inner wall step of knife rest 1 and annular retaining ring 32, make adjusting rod 3 have always
The trend to offset with push rod 4 is moved backward, in addition, the Z-Correct bump mapping Z-correct convenient for can be manually rotated is equipped on the rotating part 43 of push rod 4,
The rotation arrows stereo identification of thickness is equipped on rotating part 43 for operating easily,.
In this way, it is only necessary to which rotating push rod 3 can be achieved with the adjusting that stroke is moved axially to adjusting rod 3, to adjust pen
Thickness, and push push rod 3 that can directly cut the taper that disconnected pen core releases knife rest 1 outside chamber.
In use, according to the thickness needs of pen tip, rotating push rod 4, when needing for pen tip to be adjusted to thin state, counterclockwise
Rotating push rod 4, so that push rod 4 is displaced outwardly, as shown in Fig. 2, the circlip 7 on push rod 4 offsets with step surface, adjusting rod 3 is in bullet
Spring 8 act under move backward, at this time pen tip protrude into 1 taper of knife rest cut a chamber depth it is most deep, be the most thin state of pen；When need by
Pen rotates clockwise push rod 4 when being adjusted to thick state, so that push rod 4 moves inwards, adjusting rod 3 is under the promotion of push rod 4 gram
It takes and is moved forward in the effect of spring 8, as shown in figure 4, when moving in place, after the annular retaining ring 32 and knife rest 1 of adjusting rod 3
End offsets, at this time pen tip protrude into 1 taper of knife rest cut a chamber depth it is most shallow, be the most thick state of pen tip；
When pen core breaks in knife rest 1, push rod 4 is pushed inward, as shown in figure 5, related hexagonal swivel nut 5, adjusting rod 3 are together
Axial advancement makes pen core fall off, and exits taper and cuts outside a chamber.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
