Abstract
A kind of point protector, it is characterised in that：Ontology is column, and respectively there are one fastener holes for tool at ontology both ends, and fastener hole is half-via, can connect pencil.The use of Convenient pencil head, reduction can be wasted, pen tip can also be protected not to be damaged, provide a kind of new approaches by the utility model.
Description
Technical field
The utility model is related to study article fields, and in particular to point protector.
Technical background
Pencil sharpening metacone head is easy to touch off；Pencil has been cut much and can have been shortened using long, it is difficult to use, many people's pencils
It is short when being difficult to hold, difficult use can be disliked and avoided and lost, cause to waste.
Utility model content
The utility model is related to a kind of point protectors, are capable of providing a kind of point protector new design philosophy.
A kind of point protector, ontology are column, and respectively there are one fastener holes for tool at ontology both ends, and fastener hole is half-via, can incite somebody to action
Pencil connects.
Further：Ontology is integrally formed.
Further：Ontology is made of plastics.
Further：It is connected by cavity between fastener hole, the diameter of cavity is less than fastening bore dia.
Further：The diameter of cavity is used to accommodate the exposed part of pencil-lead.
Further：Ontology is made of metal.
Further：Between fastener hole and cavity there is pyramidal cavity to prevent pencil-lead for preventing pencil to be excessively inserting
Exposed part top it is touched.
Further：Ontology is separate structure, is made of multiple components.
Further：Also there is elastic material on fastener hole inner wall, enhance the frictional force of fastener hole.
Further：Ontology is transparent.
Technology contents illustrate and advantage.
In use, the tail portion of two very short pencil stubs can be inserted into the first fastener hole, the second fastener hole utilizes friction
Power fastens, spreading pencil stub, makes originally short and is difficult to the elongated good gripping of the pencil stub held, can also support two different thick
Carefully；Pen tip is inserted into the first fastener hole, the second fastener hole, is fastened using frictional force, exposed pen core is partially received in cavity,
It is not touched, therefore pen tip can also be protected not touched damage.
The use of Convenient pencil head, reduction can be wasted, pen tip can also be protected not to be damaged, provide one by the utility model
Kind new approaches.

Embodiment 1, picture 1-4, a kind of point protector, ontology S1 be column；Ontology S1 has a first end and a second end；Ontology
It is upper that there is the first fastener hole S2-1, the second fastener hole S2-2, the first pyramidal cavity S3-1, the second pyramidal cavity S3-2, cavity S4；With
One end upwards by body axis perpendicular to the ground in a manner of place observation have following feature；The depth of first fastener hole S2-1 is less than
The half of the height of ontology S1, the upper end opening of the first fastener hole S2-1 is in the top surface of ontology S1；The depth of second fastener hole S2-2
Degree is less than the half of the height of ontology, and the lower ending opening of the first fastener hole S2-1 is in the bottom surface of ontology S1；First pyramidal cavity S3-1
Big end be open upward；Second pyramidal cavity S3-2 is open big end downward；First pyramidal cavity S3-1 be open big end opening it is straight
Diameter is less than the minimum diameter of the first fastener hole S2-1；Second pyramidal cavity S3-2 be open big end opening diameter be less than second fastening
The minimum diameter of hole S2-2；The big end of first pyramidal cavity S3-1 openings is connected with the lower end of the first fastener hole S2-1 to be communicated；Second
The big end of pyramidal cavity S3-2 openings is connected with the upper end of the second fastener hole S2-2 to be communicated；The upper end of cavity S4 and the first pyramidal cavity
The small ends that are open S3-1 communicate；The small end that is open the lower end of cavity S4 and the second pyramidal cavity S3-2 is connected and communicates.
Embodiment 2, on the basis of embodiment 1, the first fastener hole S2-1, the second fastener hole S2-2 are six prismatic holes.
Embodiment 3, on the basis of embodiment 1, the first fastener hole S2-1, the second fastener hole S2-2 are round hole.
Embodiment 4, on the basis of embodiment 1, be made of integrated molding.
