Abstract
The utility model discloses a kind of Antibreaking pen, belong to schooling apparatus.Feature is described pen core middle front part peripheral hardware stopper protrusion, extension spring is established in the described lower pen cap and upper pen cap junction, the magnetic pressing component of the anterior peripheral hardware tool of the lower pen cap, sheathed undertaking parts on described pen core, accepting parts is resisted against in stopper protrusion, pressing component matches with undertaking parts, during use, holds pressing component, pen core is depressed, once after pen leaves hand, pen core is retracted under extension spring effect, avoids nib contact to earth and damage.Advantage is that this is novel, and structure letter is gathered, rationally, makes full use of the pressure produced when holding a pen and pen core is forced out, once after pen leaves hand, pen core is retracted under extension spring effect, avoids nib contact to earth and damage, effectively cuts the waste.
Description
Technical field
The utility model belongs to study article, particularly relates to a kind of pen.
Background technology
Pen, for student and other crowds in need, is indispensable stationery in life.Existing kind is a lot of in the market, and most widely used is gel ink pen, such as morning twilight gel ink pen, due to the special construction of gel ink pen itself, nib, once after contacting to earth, causes writing and has some setbacks, even cannot use, pen core directly abandons by people mostly, and waste is serious.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of Antibreaking pen, and structure is simple, practical, effectively prevents nib from contacting to earth, and avoids nib to damage the waste caused.
A kind of Antibreaking pen, comprise the pen cap, the lower pen cap and pen core, the upper pen cap coordinates with external threading of starting writing, be characterized in described pen core middle front part peripheral hardware stopper protrusion, extension spring is established in the described lower pen cap and upper pen cap junction, the magnetic pressing component of the anterior peripheral hardware tool of the lower pen cap, sheathed undertaking parts on described pen core, accepting parts is resisted against in stopper protrusion, and pressing component matches with undertaking parts.
The utility model improves further, and described pressing component comprises and pushing shrapnel and projection, and projection is bonded in the inboard center pushed shrapnel, and projection is made by magnetic material, and the head of projection is in wheel dentation.
The utility model improves further, described undertaking parts comprise the collar and annular brace sheet, support chip is fixed on the downside of the collar, the outside of the collar is in wheel dentation, and consistent with the shape of projection, the lower end symmetry of support chip offers two notches, the degree of depth of notch is greater than the height of stopper protrusion, after pen core is inserted by notch, rotate, be convenient to change pen core.
Compared with prior art, advantage is that this is novel, and structure letter is gathered, rationally, making full use of the pressure produced when holding a pen makes pen core be forced out, once after pen leaves hand, pen core is retracted under extension spring effect, avoid nib to contact to earth and damage, effectively cutting the waste.
Accompanying drawing explanation
Illustrate below in conjunction with accompanying drawing and the utility model is further illustrated.
Fig. 1 is a kind of structural representation of Antibreaking pen.
In figure: under the upper pen cap of 1-, 2-pen core, 3-extension spring, 4-, the pen cap, 5-pressing component, 6-accept parts, 7-stopper protrusion.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.
As seen from Figure 1, a kind of Antibreaking pen, comprise the pen cap 1, the lower pen cap 4 and pen core 2, the upper pen cap coordinates with external threading of starting writing, described pen core middle front part peripheral hardware stopper protrusion 7, extension spring 3 is established in the described lower pen cap and upper pen cap junction, the magnetic pressing component 5 of the anterior peripheral hardware tool of the lower pen cap, sheathed undertaking parts 6 on described pen core, accepting parts is resisted against in stopper protrusion, pressing component matches with undertaking parts, during use, hold pressing component, pen core is depressed, once after pen leaves hand, pen core is retracted under extension spring effect, avoid nib to contact to earth and damage.
Be it can also be seen that by Fig. 1, described pressing component 5 comprises and pushing shrapnel and projection, and projection is bonded in the inboard center pushed shrapnel, and projection is made by magnetic material, and the head of projection is in wheel dentation.
Be it can also be seen that by Fig. 1, described undertaking parts 6 comprise the collar and annular brace sheet, support chip is fixed on the downside of the collar, the outside of the collar is in wheel dentation, and consistent with the shape of projection, the lower end symmetry of support chip offers two notches, the degree of depth of notch is greater than the height of stopper protrusion, after pen core is inserted by notch, rotate, be convenient to change pen core.
