Abstract

The utility model relates to a pen core sharpener. A guide column is arranged inside a pedestal, a guide groove is arranged on the guide column, a spring-fixing cover is arranged on the bottom surface of the pedestal, a sucker is arranged below the spring-fixing cover and capable of being fixed on a plane, a protrusion is arranged on the outer side of a cutter holder and engaged with the guide groove on the inner side of the guide column, and a spring is arranged between the cutter holder and the spring-fixing cover. When the pen core is inserted into a pen core hole, a spring below the cutter holder absorbs the excessive downward pressure and the guide column and the guide groove are engaged with a top cover and a fixing sleeve on the upper side, so as to correct the biased component forces of the pen body and the pen core. Besides, the sucker made of the flexible material is convenient to be held by one hand and can bear the angular deflection of the whole structure, so as to prevent the pen core from being broken due to the incorrect placement angle. Furthermore, a sliding block arranged the upper cover can automatically close under the action of a spring after the pen body is taken out, thereby preventing the leakage and pollution of the lead waste.

Description

The pen core sharpener

Technical field

The utility model relates to a kind of pen core sharpener, utilizes spring to absorb excessive external force, and keeps certain pressure, makes blade holder keep vertical moving with guide pillar and guide groove, cooperates the sucker of soft materials, fractures to prevent pen core.

Background technology

The pencil of general pencil and automatic feed mechanism respectively has the characteristics of different demands, the advantage of the more comprehensive two kinds of pencils of its engineering pen, not only can draw the style of writing of general pencil, therefore also conveniently replaced pen core and adjustment pen core length are subjected to being extensive use of of each domain engineering personnel gradually.And the pressing cover of engineering pen upper end; be generally small-sized pen core sharpener; this pen core sharpener commonly used; be to the pen core rotary grinding with this structure; but engineering pen and pen core volume, weight are all greater than pen core sharpener commonly used; therefore application of force direction and power are difficult for controlling; when excessive or application of force direction tilts when the application of force; the pen core skin is because of the xylem protection of pencil as none; it is easy breakdown; and the diameter of bore of small-sized pen core sharpener is equivalent to the pen core diameter approximately, so the situation of breakdown in inside often is difficult for taking out and brings inconvenience, therefore needs further improvement.

The utility model content

In view of above-mentioned various technical problems, the inventor satisfies the pen core sharpener that research and development more are applicable to above-mentioned pen core, to prevent the pen core breakdown.

The utility model is a kind of pen core sharpener, and the bottom surface of base is provided with the spring fixed cap, and inside is provided with guide pillar, and the guide pillar inboard is provided with guide groove; Be provided with spring between spring fixed cap and the blade holder, protruding the pulling that is arranged at blade holder can be matched with the guide groove of guide pillar inboard, when pen core penetrates reservoir hole, the blade fixed mount imposes and presses down and rotate external force, the spring of blade holder below not only can absorb the excessive external force that presses down, and have the blade that blade holder upwards is provided concurrently and keep fixing grinding force, again by top cover and fixed cover above guide pillar and the guide groove cooperation, to correct crooked non-perpendicular component, and the sucker of spring fixed cap below soft materials can be fixed in the plane and makes things convenient for one-handed performance, can bear the overall structure angular deflection, to prevent the pen core breakdown; And the utility model is except the main goal of the invention that prevents pen core and fracture, and the slide block that its loam cake is set utilizes the active force of spring, but makes slide block auto-closing after penholder takes out, and pours out to prevent plumbous bits.Therefore the utility model not only has the function that prevents that pen core from fractureing, and can prevent that also plumbous bits from overflowing contaminated environment.

The specific embodiment

Below with regard to structure function of the present utility model, adopt by preferred embodiment, after conjunction with figs. describes in detail, to increase to understanding of the present utility model; The utility model is a kind of pen core sharpener, sees also shown in the accompanying drawing 1～10, and primary structure comprises base 1, blade holder 13, blade 14, loam cake 2, slide block 22, top cover 23, fixed cover 24 and sucker 3, wherein:

Consult shown in the accompanying drawing 1～2, base 1 inside is provided with guide pillar 12, the inboard of guide pillar 12 is provided with guide groove 121, and the bottom surface is provided with spring fixed cap 11, spring fixed cap 11 belows are provided with sucker 3, its blade holder 13 is arranged between two guide pillars 12, and inside is provided with blade 14, is provided with spring between this blade holder 13 and the spring fixed cap 11; Loam cake 2 can be covered on base 1, and the side is provided with clip 21, and upper grooves is provided with slide block 22, and slide block 22 inside are provided with spring, and end face is provided with top cover 23, and top cover 23 central authorities are provided with the fixed cover 24 that can cooperate the penholder section configuration.

Consult shown in the accompanying drawing 1～10, pen core sharpener of the present utility model can utilize that sucker 3 is auxiliary to be fixed in the plane and to make things convenient for one-handed performance, pen core with engineering pen is an example, pen core stretches out penholder to certain-length, pen core is put into by fixed cover 24, push slide block 22, it is opened to both sides, cooperate the sucker 3 of soft materials to make overall structure can bear the angular deflection that penholder is put into, avoid pen core because of putting into the i.e. breakdown before grinding of incorrect angle, when pen core penetrates the reservoir hole of blade holder 13, pen core contactor blade 14, the user imposes the external force that presses down rotation, the spring of blade holder 13 below fixation pressures is except bearing the excessive external force that presses down, its spring also can upwards provide blade 14 to keep fixing grinding force, pull 131 with set protruding in blade holder 13 sides, cooperate guide pillar 12 and guide groove 121 to move, just rectifiable crooked component, make penholder and pen core can keep vertical fixation pressure rotary grinding, avoid pen core because of application of force breakdown improperly, and in order to increase the use durability degree of pen core single grinding, the pen core conical tip that its grinding is finished is a small plane, but not complete sharp-pointed circular cone; After grinding finishes, penholder is withdrawed from, slide block 22 inner set springs hold to both sides, provide slide block 22 to the closed reaction force of central authorities, closing reservoir hole pollutes to prevent that plumbous bits from pouring out, therefore the utility model not only has the anti-function that fractures of pen core, also has the function that prevents that plumbous bits from polluting concurrently.

The above; it only is preferred embodiment of the present utility model; when can not with as limiting the scope that the utility model is implemented, all equivalent variations or modifications of being done according to the utility model claim must belong in the protection domain that the utility model patent contains.
