Description
Technical field
The utility model relates to a kind of pencil, particularly a kind of propelling pencil.
Background technology
Propelling pencil is the stationery that often uses in a kind of daily study, owing to have reusable having a few, so propelling pencil has obtained using widely, at present, propelling pencil on the market can be described as varied, but, these propelling pencils have a common shortcoming, can only use the lead for retractable pencil of diameter exactly as 0.5-1mm, use the bigger lead for retractable pencil of diameter if desired, because the clamping force of propelling pencil clamping body is limited, so do not lived with regard to clamping, at this moment, just have to reuse wooden pencil.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of simple in structure, easy to use and can clamp the propelling pencil of lead bullion core.
In order to solve the problems of the technologies described above, propelling pencil of the present utility model, comprise handwriting, be placed in lead for retractable pencil in the handwriting, place the cap of handwriting tail end and be located at the nib body of handwriting front end, the front end of described handwriting is provided with an annular groove near the position of nib body, the upper end of described nib body is provided with an annular protrusion, be provided with a gripping sleeve that is used to clamp lead for retractable pencil in the described nib body, described gripping sleeve is provided with a horn mouth.
Propelling pencil of the present utility model, described clamping body is to be made by the elastomeric material with favorable elasticity.
Propelling pencil of the present utility model, the bottom of described annular groove is provided with spring, and the top of described spring leans against on the described annular protrusion.
Propelling pencil of the present utility model, the diameter of described lead for retractable pencil are 0.5-5mm.
The beneficial effect that the utility model is obtained is: (1) mechanism is simple, easy to use; (2) be provided with a gripping sleeve that is used to clamp lead for retractable pencil in the nib body, this gripping sleeve can clamp the lead bullion core, thereby can substitute wooden pencil fully.
