Abstract
The utility model relates to a track-seam propelling and guiding pencil which comprises a penholder with a hollow cavity, a lead core, a pen clamp and a rubber which is connected at the top of the penholder. The utility model is characterized in that the upper part of the penholder with a hollow cavity is provided with a moving bolt which can push down the lead core; the top of the penholder is equipped with a barrel-shaped pincers type spring clip for clipping the rubber, and the writing end of the penholder is equipped with a lead core hoop sleeve. The utility model can use the lead core of the pencil which is made of the same wood, which has the same diameter and the different hardnesses and can change a rubber head; the track-seam propelling and guiding pencil has the advantages of simple structure, reasonable structure, and convenient use, can randomly satisfy the different requirements of different thicknesses and depths, and can save large numbers of rare woods.
Description
The utility model relates to a kind of rail gap derivation propelling pencil, particularly uses the propelling pencil with wooden pencil lead same diameter.
People generally use wooden pencil or propelling pencil at present.Wooden pencil has the thickness of pencil lead can be determined according to different needs, especially with the pencil of rubber, also removed the trouble that needs to be equipped with in addition rubber from, but wooden pencil needs often cutting, also need consume a large amount of precious timbers.Propelling pencil has easy to carry, advantage such as need not cut, but the thickness and the depth of lead for retractable pencil are selected to be limited to, simultaneously owing to lead for retractable pencil more carefully causes the low use that limits propelling pencil of intensity.
The purpose of this utility model is to provide a kind of and can uses with the different hardness lead for retractable pencil of wooden pencil lead same diameter and the rail gap derivation propelling pencil of replaceable rubber tip.
The purpose of this utility model is achieved by the following technical solution: rail gap derivation propelling pencil comprises the penholder that has cavity, with the lead for retractable pencil of wooden pencil lead with diameter, pen blocks and is connected in the rubber on penholder top, its main points are that the top at the penholder of band cavity is provided with the movable bolt of downward promotion lead for retractable pencil, tubular jaw type spring clip is equipped with rank folder rubber in the top of penholder, and the writing end of penholder is equipped with lead for retractable pencil hoop cover.
The utility model is simple and reasonable for structure, and is easy to use, can choose the lead for retractable pencil of different hardness as required wantonly, only cuts the lead for retractable pencil tip, can satisfy the requirement of different thicknesses, can save a large amount of precious timbers.
Accompanying drawings most preferred embodiment of the present utility model.
