Technical field

The utility model relates to stationery, and particularly pen digs.

Background technology

Sharpen a pencil and use manually pen plane usually, be widely used because of it has characteristics simple in structure and easy to use.Traditional pen digs does not have wood chip and lead for retractable pencil powder collection device, and in use wood chip of Chan Shenging and lead for retractable pencil powder need to collect with vessel (paper or box) in addition, and be very inconvenient also unhygienic.Therefore, needing to design and make a kind of pen with wood chip gathering-device digs.

The innovation and creation content

The purpose of this utility model is to propose a kind of band tube pen to dig, and it can be with the wood chip of generation and the recovery of lead for retractable pencil powder in the process of sharpening a pencil; Have simple in structure, good looking appearance and characteristics such as easy to use.

The utility model can be achieved through the following technical solutions:

Band tube pen digs, include cylinder and pen plane, planing means has the hand of disjunctor to hold portion, piston part and pen dig body, pen plane body is provided with taper and cuts a hole and penknife is installed, the nozzle diameter of piston part and cylinder is suitable, can make the piston part insert cylinder with the nozzle capping, and the pen plane body that penknife is housed is placed in the cylinder, it is characterized in that: taper is cut the aperture in a hole away from the piston part, the bottom eccentric position of cylinder has locating hole, hold portion by relatively rotating cylinder with a hand that digs, alignd or dislocation in the locating hole of cylinder and the aperture that a hole is cut in the taper of pen plane.

As optimization, a cylinder and a planing means have locking mechanism: the inboard nearly tube port position of cylinder is provided with the semi-ring draw-in groove, and half section of the semi-ring draw-in groove or stage casing have the notch that leads to nozzle, and the piston part that pen digs is provided with a convex clip position that can enter the semi-ring draw-in groove by this notch.

Use step:

One, pen piston part of digging and pen that penknife is housed dig a body and inject in the cylinder, and at this moment pen digs, and to cut an aperture close with tube bottom/touch; The hand portion of holding that pen digs is positioned at the cylinder nozzle outside, and the aperture of cutting that pen digs misplaces mutually with the locating hole of opening at the bottom of the cylinder.

Two, sharpen a pencil, the hand portion of holding that holds the pen plane makes relative rotation with cylinder, and the locating hole of opening at the bottom of an aperture and the cylinder of cutting that pen is dug aligns.Can pass the pencil end hole of cutting that locating hole enters pencil-knife and sharpen a pencil this this moment, and wood chip that sharpens a pencil and lead for retractable pencil powder are stayed the pen that pen digs and dug in body and the cylinder.

Three, lock tube, the hand portion of holding that holds the pen plane makes relative rotation with cylinder, at this moment, the convex clip position that pen digs on the piston part moves in one side draw-in groove of cylinder, pen digs and can not extract from cylinder, the aperture of cutting that pen digs misplaces mutually with the locating hole of opening at the bottom of the cylinder, and the locating hole at the bottom of the cylinder is dug the body end by pen and cuts out, and wood chip that had before sharpened a pencil and lead for retractable pencil powder are stayed pen and dug in body and the tube.

Pen need be dug when cylinder is extracted, pen is dug the state that rotates to step 1 with respect to cylinder, even align with notch on the cylinder in the convex clip position that pen digs on the piston part, under this state, the piston part that can at any time pen be dug and a pen plane body take out in cylinder.

Further design of the present utility model is to be provided with rubber erasers in the hand portion of holding that pen digs: the hand portion of holding is coniform, and hand is held and established a rubber erasers storehouse in the portion, and a rotary extension rubber erasers device is plugged in the rubber erasers storehouse.
