This cutter shaft 30 is on the rotating axis hole 222,232 that is arranged in two support portions 22,23 on the tool rest 20, the rough internal diameter that equals axis hole 222,232 of the external diameter of cutter shaft 30, make cutter shaft 30 be able to firm 222,232 of two axis holes that are arranged at, be concaved with an annular groove 302 at cutter shaft 30 front end places again, and making cutter shaft 30 be positioned at the internal diameter of the external diameter at annular groove 302 places less than preceding support portion 22 axis holes 222, the rear end of cutter shaft 30 is run through the axis hole 232 of support portion 23, back and is stretched within the board slot 25 again.
This spring 36 is sheathed on the front end of cutter shaft 30, the strength of cutter shaft 30 1 pushing and pressing is provided, cutter shaft 30 non-formation annular grooves 302 places are matched with the axis hole 222 of preceding support portion 22, and allow cutter shaft 30 firm be arranged at 222,232 of two axis holes, on the side of tool rest 20 front ends, be convexly equipped with to be formed with in the preceding support portion 22 of tool rest 20 again and protect edge 27, and be connected with a protecting cover 28 on the edge 27 protecting, and be formed with one and can stretch into wherein for cutter shaft 30 front ends protecting 28 of edge 27 and protecting covers, and the space of putting spring 36, and make an end of spring 36 be resisted against on the protecting cover 28.
This cutter 32 is rotating to be sheathed on the cutter shaft 30 and to be placed in the accommodation space 24 of tool rest 20, it can be forms such as columniform hobboing cutter or planing tool, the axis of the axis of this cutter 32 and tool rest 20 can be an angle of inclination, and the periphery of cutter 32 can be through the holes of accommodation space 24 bottoms and is inserted in the cutting hole 202 of extension, in order to the cutting pencil, again at the fixedly connected gear 34 that is sheathed on the cutter shaft 30 that is provided with of an end of cutter 32, to be connected with the transmission device of electric pencil sharpener by this gear 34, cutter 32 can be rotated relative to tool rest 20 and cutter shaft 30 by drive, secondly, on an end of tool rest 20 front ends, can be provided with a pad 38 that is sheathed on the cutter shaft 30 at cutter 32.
This sliding panel 40 slidably is arranged at the bottom of tool rest 20, it can slightly L-shaped bending, and be formed with a upright stop surface 402 at front end, and form a horizontal joint face 404 in the rear end, joint face 404 is provided with a connecting hole 406, be convexly equipped with the sandwich sheet 403 that is formed with two intervals in addition respectively in the both sides of stop surface 402, but and tool rest 20 two bottom sides be convexly equipped with respectively be formed with clamping in the relative guiding rib 26 between the sandwich sheet 403, by cooperatively interacting of sandwich sheet 403 and guiding rib 26, can make sliding panel 40 relative tool rests 20 slide.
What this gripper shoe 42 can be swung is connected on the sliding panel 40, and be placed in the board slot 25 of tool rest 20, and its two sides respectively with board slot 25 in pushing and pressing part 252 and the rear end of cutter shaft 32 lean, be convexly equipped with in gripper shoe 42 bottoms and be formed with the connection protuberance 422 that is incorporated into connecting hole 406 on the sliding panel 40 that can swing.
In use, the user can insert pencil in the cutting hole 202 of the body 50 of pencil sharpener and tool rest 20, and the drive unit that passes through electric pencil sharpener drives knife rest group 52 and cutter module 10 rotates relative to body 50 simultaneously, and make cutter 32 relative tool rest 20 rotations with a transmission device, the pencil that is inserted with cutting thus.
Please cooperate again referring to Fig. 6, after pencil is cut to predetermined sharp degree, the nib that be sharpened this moment can push against the stop surface 402 of sliding panel 40, and move the rear end that promotes sliding panel 40 relative orientation tool rests 20, along with the slippage of sliding panel 40 and the pushing and pressing of pushing and pressing part 252, can drive position side oscillation before tool rest 20 that gripper shoe 42 and cutter shaft 30 lean, and pushing and pressing cutter shaft 30 side shifting before tool rest 20, when cutter shaft 30 moves to the axis hole 222 of its annular groove 302 and preceding support portion 22 when relative, because of the external diameter at cutter shaft 30 annular grooves 302 places internal diameter less than axis hole 222, so axis hole 222 also can't provide the effect of cutter shaft 30 firm support, at this moment, but 32 on cutter tool rest 20 relatively is swing state, and so the cutting pencil that just can not continue produces with the situation of avoiding excessively cutting pencil; After pencil after the user will fine away takes out in cutting hole 202, the recovery elastic force that can utilize spring 36 to be provided, promote cutter shaft 30 and return back to position with axis hole 222 secure fit, and drive gripper shoe 42 and sliding panel 40 returns back to original position, to treat the pencil cutting operation of next time.
And when cutter 32 has abrasion because of use, can be with cutter module 10 along the slot on the knife rest group 52 522 and by extracting out in the body 50, and new cutter module 10 changed insert in the body 50, so the user can not need abandon whole electric pencil sharpener, the waste of resource can be reduced, and the use cost of electric pencil sharpener can be significantly reduced.
