Abstract
The utility model relates to a self rotation mechanism of a pencil sharpener, comprising a pusher dog plate, a tray, a locking claw, a hollow shaft ratchet wheel, a check pawl, an offsetting spring, a main drive shaft and a lockup seat, wherein the pusher dog plate is linked with the main drive shaft; the hollow shaft ratchet wheel threads through the pusher dog plate, the tray and the offsetting spring and is fastened on the lockup seat; two legs of the offsetting spring are respectively positioned on the pusher dog plate and the tray; the locking claw and the check pawl are reamed with the tray; the check pawl is matched with the hollow shaft ratchet wheel and one end of the check pawl is linked with the pusher dog plate. The utility model overcomes the disadvantages on prior art that the cutting knife has to roll and revolve around the pencil, which leads to that the self rotation mechanism of the pencil sharpener is large in size and is inconvenient to carry. The utility model can enable the pencil to revolve, greatly reducing the work space of the cutting knife. The utility model has the advantages of simple and compact structure, strong reliability and is convenient to carry after assembly.
Description
The utility model relates to a kind of pencil sharpener pencil free-wheeling system.
Traditional pencil cutting mechanism is divided into two kinds of hilted broadsword formula pencil-knife and hob type pencil sharpeners, the phenomenon of hilted broadsword formula pencil-knife pencil-lead fracture in working angles is very serious, need Repeated Cutting, influence the life cycle of pencil, eliminated by market gradually at present.Though the hob type pencil sharpener has solved the disconnected core problem in the working angles, has cutting effect preferably, but its volume is bigger, and the carrying of inconvenient student, its main cause is that pencil itself is not done any action in the course of the work, and need bite to do the roller rotation around fixing pencil, this just needs a relatively large working space, cause the volume of complete machine can't dwindle at all, therefore, the working method of bite roller rotation that only changes, and make pencil produce rotation, just can save unwanted working space, thereby reduce volume.
The purpose of this utility model is to solve all to need bite to center on fixing pencil in the prior art to do the roller rotation and just can finish cutwork, thereby causes the volume of product big, the problem that inconvenient student carries.The utility model is made of claw plate, pallet, lock pawl, hollow shaft ratchet, check pawl, back-moving spring, power transmission shaft and locking bed, claw plate and power transmission shaft interlock, the hollow shaft ratchet wore claw plate, pallet and back-moving spring simultaneously, and be fastened on the locking bed, two spring pin of back-moving spring are positioned at respectively on claw plate and the pallet, lock pawl and check pawl and pallet are hinged, and wherein check pawl matches with the hollow shaft ratchet, an end and the claw plate interlock of lock pawl.
In the interlock mouth on the one end insertion claw plate of lock pawl.
The end of pencil enters the back by the locking of lock pawl by the hollow shaft ratchet, and after power transmission shaft turned clockwise, the pencil and the bite that cooperatively interact were rotated counterclockwise simultaneously, thereby reached the purpose of cutting pencil.
The utility model is by above-mentioned specific design, can make pencil produce rotation, bite needn't just can be finished cutting to pencil around pencil revolution, can dwindle the working space of bite greatly, have advantage simple and compact for structure, good reliability, make portably using of complete machine more become convenient after the whole assembling.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation after the utility model and the final assembly.
As shown in the figure, the utility model is to be made of claw plate 1, pallet 2, lock pawl 3, hollow shaft ratchet 4, check pawl 5, back-moving spring 6, driving shaft 7 and locking bed 8, claw plate 1 and power transmission shaft 7 interlocks, hollow shaft ratchet 4 wore claw plate 1, pallet 2 and back-moving spring 6 simultaneously, and be fastened on the locking bed 8, two spring pin of back-moving spring 6 are positioned at respectively on claw plate 1 and the pallet 2, lock pawl 3 and check pawl 5 are hinged with pallet 2, wherein check pawl 5 matches with hollow shaft ratchet 4, an end and claw plate 1 interlock of lock pawl 3.Its serial verb construction is that an end of lock pawl 3 inserts in the interlock mouth 9 on the claw plate 1.During use, rotate counterclockwise power transmission shaft 7 earlier, at this moment, power transmission shaft 7 drives claw plate 1 by gear 10 and turns clockwise, the check pawl 5 that is hinged on the pallet 2 leans on hollow shaft ratchet 4, and pallet 2 can not rotate, and claw plate 1 is stirred three lock pawls 3 that are hinged on the pallet 2 simultaneously and opened relatively.After hollow shaft by hollow shaft ratchet 4 inserted pencil jack 12 in the locating rack 11 with the pencil end, back-moving spring 6 resetted, and claw plate 1 counter-rotating drives three lock pawls 3 and stings tight pencil.Clockwise rotate power transmission shaft 7 again, at this moment, power transmission shaft 7 drives bite 13 by the gear train transmission mechanism and is rotated counterclockwise, simultaneously, power transmission shaft 7 drives claw plate 1 by gear 10 and is rotated counterclockwise, and the check pawl 5 that is hinged on the pallet 2 is in released state with hollow shaft ratchet 4, is hinged on that three lock pawls 3 on the pallet 2 drive pallets 2 and pencil rotates in the same way, cooperates with bite 13 to reach the purpose of cutting pencil.
