Description
Technical field
The present invention relates to a kind of stationeries, more particularly, to a kind of electronic straight knife type for realizing delay by mechanical structure
Pencil sharpener.
Background technology
Pencil sharpener is a kind of tool for sharpening a pencil, and now general use on the market is all manually penknife mostly.
Pencil is inserted into cutter, passes through manual rotation knife by manual penknife, the general cutter with shell and setting on the rotary shaft
The mode of tool either Propelling pencil with sharpener in cap, to cut pencil, this pencil sharpener is when in use, it is necessary to constantly rotation volume pen
Device can be only achieved the purpose to sharpen a pencil, and not only efficiency is low, and unevenness of slightly exerting oneself is easy for breaking pen core.
The electronic straight knife type pencil sharpener now designed, is arranged motor on the rotary shaft, is revolved in band cutter by motor
Turn, is automatically performed cutting function.Automatic straight knife type pencil sharpener with motor substitutes manual operations so as to cut pen more convenient, but city
Automatic straight knife type pencil sharpener on face still needs user's hand control switch, when is starting to sharpen a pencil, when is closing and cut
Device, is required for the control of user.And the time for cutting pen for the user is not easy to control, the time has grown pen tip quilt
Cut it is excessive cause to waste, the time, short then pen tip was not yet sharpened.If cutting pen with regard to stopping after sharpening pen, pencil
Pen tip does not form the conical structure in rule, and not only appearance unsightly, and influences the feel that uses.Therefore, how control
The feed distance of the time and pencil of cutting pen are the important research directions of existing electronic straight knife type pencil sharpener.
Invention content
Technical problem to be solved by the invention is to provide a kind of electronic delay straight knife type pencil sharpeners, realize pencil cutting pen
Pencil stroke is controlled after point, avoids excessively cutting, and carry out delay cut-off by mechanical structure, it is ensured that pencil point slippery feel
It is good.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of electronic delay straight knife type pencil sharpener, packet
The internal outer housing for being equipped with power supply module, the knife rest with straight knife piece, motor is included, is passed through between the power supply module and motor
First shrapnel, the second shrapnel are connected after connecting, and gear member, the gear member and electric rotating are arranged on the knife rest
Machine connects and is provided with below touch part, and first shrapnel is mounted on the bottom of touch part side, second bullet
Piece is mounted on the lower section of touch part and between the first shrapnel there are spacing, and geared worm holding is embedded in the gear member

Tensional state applies power that is radial along geared worm, pulling out to sliding block.The effect of tension spring be complete pencil cutting after,
Drawing returns to original state sliding block.
Compared with the prior art, the advantages of the present invention are as follows the contacts that the present invention passes through the first shrapnel and the second shrapnel first
Whether connection whether conducting to control power supply, turn-on power then plane by motor rotation straight knife piece, and deenergization then stops
Planing.The present invention by pencil be inserted into knife rest setting turn-on power, then pencil move to where, straight knife piece planing to when
It is stopped, is the major issue to be solved.Resistance block is arranged in the present invention in knife rest, after the pen tip of pencil is cut point,
The pen tip of pencil, which will move down, touches resistance block.Resistance block will move preset distance under the action of pencil, to push
Geared worm, while the position of pencil is limited so that pencil no longer moves down.The present invention need to do is to fining away at this time
Pencil surface afterwards further cuts certain time length so that pencil point slippery feel is good.To achieve the goals above, of the invention
Geared worm is arranged with sliding block to coordinate, because the effect of resistance block, geared worm have moved downward scheduled distance, sliding block allowed to support
On the rotation screw thread of geared worm.Gear member drives geared worm to continue to rotate at this time, and geared worm will be made to do downwards
The movement of rotation, after being driven worm movement to certain distance, that is, scheduled duration, geared worm will support and open the second contact chip, from
And realize deenergization.Complete all planing work.The pencil taken out at this time exempts from excessively to cut and causes to waste, and pen tip
Slippery feel is good.
In conclusion the present invention removes to improve existing straight knife type electric pencil-sharpening unit certainly by the way that new mechanical structure is arranged
Deficiency in terms of dynamic cutting, perfect the degree of automation of straight knife type electric pencil-sharpening unit.
