Summary of the invention

The purpose of the utility model is to propose a kind of environment protection type pencil to dig, and it has cuts that pen back pen bits are difficult for leaking outside, advantage easy to use and portable.

The purpose of the utility model can realize through following technical scheme:

A kind of environment protection type pencil digs; It includes a barrel portion, cap, two knife rest of opening sliding door device, loam cake and blade being installed, and bucket portion is the uncovered cylindrical shell of end face, has the cap pen port on the cap; Knife rest has conical pen paring hole; Blade is installed on the side of conical pen paring hole, and the below that knife rest is located at cap makes the pen paring hole of knife rest communicate with the cap pen port is coaxial, and cap can be placed on the open-mouth of barrel portion and knife rest is hidden in barrel portion;

Two sliding door devices of opening include and two open slide and spring, and two slides of opening are 2 slide plates that are symmetrically set on the cap, and an end of slide plate is movably connected on the cap through axle; The other end of slide plate is a movable end; The movable end outside is provided with inserting column, and spring is located between the inward flange of slide plate and cap, and cap is provided with bar-shaped trough in spring position; Spring partly is hidden in the bar-shaped trough; One end of spring is plugged in the inserting column of slide plate, and the other end of spring is connected to the inward flange of cap, and 2 slide plates can rotate around the axis to make and twoly drive slide and open or close;

Loam cake is the uncovered housing in bottom surface; Loam cake is located at the cap top and will be twoly opened sliding door device by its open-mouth and hides; Loam cake has and the corresponding loam cake pen port of cap pen port, twoly drives slide and loam cake is pressed close to, and the center of its corresponding loam cake pen port has the taper recess.

Prioritization scheme is that said bucket portion and cap are triangle, all have hand-held room on each side of bucket portion.

In the utility model, two slides of opening make the loam cake pen port of loam cake be in normal off status, when cutting; The nib of pencil is exerted oneself at two taper recess places that drive slide gently, just can two slides of opening opened and cuts pen, and this moment, spring was in contraction state; After taking out pencil, spring stretches to make twoly opens the slide closure, and the loam cake pen port of loam cake recovers closed condition again; Like this, the pen bits in the bucket portion just can not leak outside; The effect that person easy to use holds is played in hand-held room in the utility model leg-of-mutton bucket portion and the bucket portion.

The utlity model has following substantive distinguishing features and progress:

1, the pen bits in the bucket portion of the utility model can not leak outside, can be relieved carry;

2, the utility model also has characteristics simple in structure, easy to use.
