Abstract
The invention provides a movable retractable pencil. The problems that the traditional wood pencil sharpening time and wood resources are wasted are solved, and the defects that the pencil lead is easily broken and the pencil lead is not tightly clamped and is easy to retract in the movable retractable pencil are overcome. The movable retractable pencil comprises a first shell, a second shell, a fixing sleeve, a positioning rod, a connecting line, a fixing pin and a pencil lead, and is characterized in that the first shell and the second shell have the generally same shape; one semi-conical end of the first shell and one semi-conical end of the second shell are respectively a conical part of the first shell and a conical part of the second shell; the rest parts are respectively a first shell column part and a second shell column part; one ends of the first shell column part and the second shell column part are provided with fixing grooves with the depth of H; a pencil lead slot matched with the diameter of the pencil diameter is formed in the center of the inner surface of the first shell and the second shell; and an inner wire slot which is parallel to and communicated with the pencil lead slot is formed below the pencil lead slot of the first shell.
Description
Technical field
The present invention relates to pencil, relate in particular to a kind of propelling pencil.
Background technology
Pencil is a kind of history writing implement long, that extensively and in a large number use, and people have all over the world carried out long-term, a large amount of research, improve manufacturing process and the preparation method of pencil, and conventional pencil comprises conventional wooden pencil and propelling pencil.Conventional wooden pencil, in use along with pencil-lead constantly spends, need be removed wooden shell from pencil one end gradually with instrument, makes pen core exposed, therefore needs the expensive time, and this pencil has spent a large amount of timber simultaneously, waste resource, adverse environment protection; Although and propelling pencil has advantages of the timber of saving and saves and cuts a time, exist the easily broken and pencil-lead of pencil-lead and hold the defect of not tightly easily shrinking back, therefore make its application be restricted.
Summary of the invention
Object of the present invention is exactly to solve the defect that above-mentioned prior art pencil exists, a kind of new mechanical pencil is provided, both solved conventional wooden pencil waste and cut a time and timber resources problem, and overcome again the easily broken and pencil-lead of pencil-lead that propelling pencil exists and hold the defect of not tightly easily shrinking back.
