Abstract

The utility model relates to a pencil sharpener, which comprises a sharpening core. The sharpening core comprises an insertion hole comprising an insertion end and a tail end. The pencil sharpener further comprises a pencil propping device which is arranged at the tail end of the insertion hole and contacted with the pencil point after the pencil is sharpened well and pressed down, a spring whichis connected with the pencil propping device and used for propping the pencil propping device upwards, as well as a triggering device arranged at the lower part of the pencil propping device and pressed down by the pencil propping device to switch on a triggering circuit, wherein the triggering circuit is connected with an alarming device. Because the pencil sharpener provided by the utility modelis equipped with the alarming device, when the pencil is sharpened well, the LED lamp is lighted to indicate that the pencil is sharpened completely and the sharpening operation can be stopped, thereby avoiding wastes caused by the continuous sharpening operation performed after the pencil is sharpened well. The LED lamp can not be turned off immediately after being lighted until the pencil is drawn out from a pencil inserting switch, so as to remind the users to remove the sharpened pencil in time.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the cross-sectional view that pen of the present utility model digs;

The cross-sectional view that pen of the present utility model dug when Fig. 2 was the pen extraction;

Fig. 3 is the cross-sectional view that the fashionable pen of the present utility model of penholder digs.

The specific embodiment

Pen plane of the present utility model LED lantern festival when digging sharp pencil is lighted automatically.Represent that when the LED lamp pencil has dug fixed sharp degree, can manually stop to dig pen and pencil is withdrawed from the pen plane, make pen dig the using electricity wisely that stops operating; Save the time of digging many pencil wastes and save pencil, can not continue to dig pen because of not knowing pencil to dig point and cause waste.Signaling transfer point schematic diagram for this reason as shown in Figure 1 and Figure 2, when the pencil-knife point when specifying point to spend, nib external force acts on the top piece that digs on the core and is promoting lamp push rod 3, make two lamp five metals sheet 5 link to each other and switch on, LED lamp 6 is lighted.Drive circuit can also be linked to each other with lamp five metals sheet 5 simultaneously, lamp five metals sheet 5 and connect, drive circuit stops to drive.

Its concrete structure digs core, pen pushing apparatus, spring, flip flop equipment for comprising, dig core and comprise patchhole, patchhole comprises insertion end and end, pen pushing apparatus is arranged on the patchhole end, pen pushing apparatus contacts and is pressed down with nib when pen digs point, and spring links to each other with described pen pushing apparatus its jack-up that makes progress, and flip flop equipment is arranged on the pen pushing apparatus below, when pen pushing apparatus presses down, connect circuits for triggering, be connected with warning device in the described logical circuits for triggering.

Wherein warning device can be LED lamp 6 or buzzer siren.Pen pushing apparatus comprises a top piece 7 that contacts with nib and the push rod 3 that is arranged on a piece 7 belows, described top.Flip flop equipment is two and is provided with the conducting strip 5 that spacing is in contact with one another the connection circuit under external force.Pen digs and also comprises fork 2, is provided with the point of rotation in the middle of the fork 2, and first end 201 of fork 2 is arranged on the insertion end of described patchhole, and fork second end 202 is arranged on the end of patchhole, and penholder is gone into patchhole promotion fork 2 and withstood push rod 3.Adopt such structure, when pen dug point, nib will be pushed down a top piece 7, and a top piece 7 is pushed down push rod 3, and push rod 3 is pushed down conducting strip 5 conducting circuits for triggering again, made alarm equipment alarm, reminded user's pen to dig point.

If electronic pen digs, pen digs and also comprises the drive unit that is used to drive described plane core rotation, and system can also cut off the power supply automatically when pen digs point, and drive unit is linked to each other with circuits for triggering, and circuits for triggering are connected drive unit and stopped to drive.

Do not continue display alarm when pen digs in order to extract out at pencil, pen of the present utility model digs and has designed following structure, and the described penholder of insertion end that has been arranged on described patchhole inserts the switch system 1 of inserting of withstanding described promotion fork first end 201.Push rod 3 comprises the push rod crossbeam 301 that stretches to described fork second end 202 directions, and push rod crossbeam 301 is that the inclined-plane cooperates with the contact-making surface of fork second end 202, and the wide end in the inclined-plane of push rod crossbeam 301 is arranged on the below.

When inserting pencil, plug in a switch system 1 and drive fork 2 simultaneously and pushing down lamp push rod 3, can not allow in the time of can making the user after finding the pencil-knife point, extract pencil out outward two lamp five metals sheet 5 leave too early and make LED lamp 6 extinguish too early; But the pencil that will dig point as the user is plugged in a switch system 1 and is set back when extracting out fully, thereby makes fork 2, lamp push rod 3, lamp five metals sheet 5 and no longer include the external force effect and reset in succession, finally makes LED lamp 6 extinguish, and properties of product restore to the original state.

Can not extinguish after the LED lamp is bright at once, detach a plug in switch system 1LED lamp 6 until pencil and just can extinguish automatically.As shown in Figure 3, fork 2 is return original position when pencil detaches the switch system of inserting 1, lamp push rod 3 because spring 4 effects pop up, thus make two lamp five metals sheet 5 break away from outage, LED lamp 6 extinguishes.

When occurring in the process of plane breaking core, pen plane of the present utility model has also disposed the instrument hair and has swept simultaneously, and the instrument hair is swept 8 and is provided with " U " font afterbody, and the top penholder that available " U " font afterbody promotes to dig on the core ejects disconnected core.
