Abstract
The utility model relates to a pencil-core sharpener which comprises a shell, a pencil-head socket, a bevel gear, a rotary drum, a socket gear, a grinding wheel gear, a taper grinding wheel and a transition gear. When the utility model is used, a handle shaft is rotated and the bevel gear drives the rotary drum to rotate. The socket gear drives the transition gear to rotate. The transition gear drives the grinding wheel gear and the grinding wheel to rotate together. Thereby, a pencil core which is inserted into the pencil-head socket is sharpened. Simultaneously a dust cleaning wheel is used for cleaning lead dust attached on the pencil core to discharge the lead dust. The utility model can be conveniently used for sharpening wooden pencil cores and propelling pencil refills and is a practical stationary article.
Description
The utility model relates to stationery, particularly a kind of manual or electronic pencil-lead sharpener.
The pencil cutter of Xiao Shouing all is that Wood pencil is planed or changeed and cut in the market, and pencil-lead is fined away, and is easy to use, but working angles comparatively bothers, and is easy to cut disconnected pencil-lead.
The present propelling pencil that generally uses, pencil-lead is thinner, write and when drawing lead for retractable pencil easily broken, especially use and brought trouble to the student.Therefore, need the overstriking pencil-lead, the pencil-lead of overstriking then is difficult for grinding.
In order to overcome above-mentioned shortcoming, the purpose of this utility model provides a kind of pencil-lead sharpener, and it is grinding Wood pencil core and propelling pencil refill easily.
A kind of pencil-lead sharpener described in the utility model comprises a shell, one pencil stub socket and some coupling spindles, it also comprise one be fixedly connected on the shell inner support on crank shaft fixedly connected, be positioned at first bevel gear on pencil stub socket right side, one and first bevel gear is connected with a joggle, with the pencil stub socket is second bevel gear in axle center, one fixedlys connected with second bevel gear, its base is installed in the rotary drum on the shell bottom plate central shaft, one socket gear in the installing of the lower cone external surface of described pencil stub socket, one passes on left in rotary drum that a grinding wheel spindle flexibly connects with rotary drum loam cake and rotary drum base plate, and the emery wheel gear of installing on the top of grinding wheel spindle, the one conical emery wheel of installing in the bottom of grinding wheel spindle, and one in rotary drum the left side, promptly flexibly connect with rotary drum loam cake and rotary drum base plate by a transition gear axle with the grinding wheel spindle rear side, and the transition gear of installing on the top of transition gear axle, described transition gear both was connected with a joggle with the socket gear, connect with the emery wheel gears engaged again, the top of described pencil stub socket is fixedly connected with shell by screw, described rotary drum base plate is provided with an above ash-falling hole, also is provided with an above ash-hole on the described shell bottom plate.
During use, the rotation crank axle, first bevel gear that is installed on the crank shaft rotates and drives second bevel gear that is installed on the rotary drum, drum rotating, the socket gear driven transition gear that is installed on the pencil-lead socket is rotated, transition gear drives the emery wheel gear again and rotates, the emery wheel gear rotates together with emery wheel, thus the pencil-lead that is inserted in the pencil stub socket is carried out grinding, the deashing wheel is removed attached to the lead ash on the pencil-lead simultaneously, lead ash is fallen into the ash-falling hole on the rotary drum base plate, and the ash-hole on shell bottom plate is discharged again.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of structural representation of pencil-lead sharpener.
Fig. 2 is the A-A cutaway view of Fig. 1.
Referring to Fig. 1 and Fig. 2, a kind of pencil-lead sharpener comprises a shell 1, a pencil stub socket 3 and some coupling spindles, and it also comprises first bevel gear 6, second bevel gear 8, rotary drum 7, socket gear 10, emery wheel gear 11, conical emery wheel 12 and transition gear 9.
