Description
Technical field
The utility model is related to a kind of propelling pencil, and in particular to one kind rotates out of lead formula environmental protection mechanical pencil.
Background technology
At present, propelling pencil goes out lead, this propelling pencil existing defects automatically using pressing：When using, one is pressed
It is secondary go out lead amount fix, it is total to need artificial adjustment, it is impossible to accomplish it is electrodeless go out lead, i.e., press every time make it is fixed go out lead length, it is impossible to
Accomplish continuously not limit for length's degree go out lead, and use after, always there is a bit of lead for retractable pencil to use, more waste.
Utility model content
The purpose of this utility model is to provide one kind and rotates out of lead formula environmental protection mechanical pencil, can continuously limit for length degree does not go out
Lead, and the lead for retractable pencil length of last waste can be reduced.
To solve above-mentioned technical problem, the technical scheme that the utility model is provided is：
One kind rotates out of lead formula environmental protection mechanical pencil, including the cap for brush, pushing ram, penholder and nib, described penholder top tool
There is opening, platform is provided with the downside of penholder upper opening, the Platform center offers square opening；Along bar on the pushing ram
Body is provided with some equidistant boss, and kidney-shaped structure is formed between adjacent lands；The cap for brush is cylinder, and cap for brush lower end card sets pen
In the platform of bar upper end, helicitic texture is provided with cap for brush lower end inside；The pushing ram is placed in the cap for brush, on propulsion club body
Boss is engaged with the helicitic texture of cap for brush lower end, the cap for brush is rotated relative to pushing ram；The pushing ram lower end limitation
In the square opening of penholder platform, pushing ram is set to be moved up and down in square opening and can not rotated；The written place is provided with
Friction clamp, the friction clamp can clamp pencil-lead.
The boss is discontinuous screw thread form.
The written side offers side opening, and the side opening is used to reclaim remaining pencil-lead, and the aperture size of side opening is more than
Pencil-lead footpath diameter, the pencil-lead that cannot be used in penholder can take out from side opening.
The friction clamp length is 1-1.5cm.
The friction clamp is flexible and aperture size of friction clamp center is less than pencil core diameter.
Beneficial effect：
The lead formula environmental protection rotatable cap for brush of mechanical pencil that rotates out of of the present utility model goes out lead, realizes continuous free of discontinuities and adjustable
Length it is electrodeless go out lead, and reduce the last lead for retractable pencil length for wasting, realize the effect for saving lead for retractable pencil.

Specific embodiment
With reference to specific embodiment, the utility model is described in further detail.
One kind rotates out of lead formula environmental protection mechanical pencil, including the cap for brush 1, pushing ram 2, penholder 4 and nib 9, on described penholder 4
Portion has opening 3, and platform 6 is provided with the downside of penholder upper opening 3, and the center of the platform 6 offers square opening 7；It is described to push away
Enter on bar 2 and be provided with some equidistant boss 10 along shaft, kidney-shaped structure 11 is formed between adjacent lands 10；The cap for brush 1 is circle
Cylindricality, the lower end card of the cap for brush 1 is set in the platform 6 of penholder upper end, and helicitic texture 11 is provided with cap for brush lower end inside；The pushing ram 2
It is placed in the cap for brush 1, the boss 10 on the shaft of pushing ram 2 is engaged with the helicitic texture 11 of cap for brush lower end, enables the cap for brush 1 relative
Rotated in pushing ram 2；The lower end of the pushing ram 2 is limited in the square opening 7 of penholder platform, enables pushing ram in square opening 7
Inside move up and down and can not rotate；Friction clamp 5 is provided with described written 9, the friction clamp 5 can clamp pencil-lead.
Further, the boss 10 is the screw thread that discontinuous screw thread form, i.e. both sides are pruned.Open the written side
Side opening 8 is provided with, the side opening 8 is used to reclaim remaining pencil-lead, and the aperture size of side opening 8 is more than pencil-lead footpath diameter, in penholder 4
The pencil-lead that cannot be used can take out from side opening 8.The length of the friction clamp 5 is 1-1.5cm.The friction clamp 5 has elasticity
And the aperture size at friction clamp center is less than pencil core diameter.
During work, during lead for retractable pencil inserted into friction clamp 5, until top is to pushing ram 2, because the hole of friction clamp 5 is dimensioned slightly smaller than
Lead for retractable pencil size, and with elasticity, so as to lead for retractable pencil be clamped.Now rotary pen cap 1, because pushing ram 2 and cap for brush lower end 1 use spiral shell
Line coordinates, and pushing ram 2 is limited by square opening in penholder 7 and cannot rotated, so pushing ram 2 is moved down, promotes lead for retractable pencil
Go out mechanical pencil, so that realizes continuous adjustable-length free of discontinuities goes out lead.Rotary pen cap 1 touches friction clamp 5 up to catch bar 2,
And friction clamp 5 only has the length of 1-1.5cm, the lead for retractable pencil length for then being wasted is greatly reduced.
After a piece lead for retractable pencil has used a residue little by little, the cap for brush 1 is inverted, pushing ram 2 is reclaimed, then another lead for retractable pencil is inserted
Enter friction clamp 5, will be unable to the lead for retractable pencil head that uses and release, rock mechanical pencil so that the lead for retractable pencil that cannot be used is from the written side of penholder
Spilt at hole 8.
The above, is only preferred embodiment of the present utility model, and any formal limit is not made to the utility model
System, any those skilled in the art are not being departed from the range of technical solutions of the utility model, according to of the present utility model
Technical spirit, any simple modification made to above example, equivalent and improvement etc., still fall within the utility model
Within the protection domain of technical scheme.
