Abstract
The utility model relates to a multiangular prism pencil with a lead core. The utility model is characterized in that the utility model is composed of a triangular prism-shaped pencil rod and a triangular prism-shaped lead cord, wherein, the triangular prism-shaped lead cord is arranged in a through hole for the triangular prism-shaped lead cord, and the through hole is arranged on the pencil rod; when the utility model is used, only the pencil rod is cut, and the lead core does not need cutting. As the lead cord is in the shape of a triangular prism having three tips, the three tips can be orderly used; after the three tips are ground to be flat, the middle part of the lead cord becomes a tip. Under the popularization and the usage of the utility model, not only a user is provided with convenience, but also timber and lead stock can be saved.
Description
The utility model belongs to a kind of pencil.
Pencil is the widely used writing appliances of students in middle and primary schools.The pencil of Chu Shouing is to be made of wooden penholder and lead for retractable pencil in the market.Lead for retractable pencil is cylindrical, and penholder is wooden cylindrical or hexagonal cylindricality.Cylindrical lead for retractable pencil is arranged on the center of penholder.Use before this pencil, must fine away cylinder cylindricality lead for retractable pencil.Sharpening is said and is easy to, but does to get up to acquire a certain degree of difficulty.Because sharpen a pencil point, students in middle and primary schools' point that sharpens a pencil particularly, one firmly slightly, and lead for retractable pencil is just cut disconnected, continue to cut earlier penholder, cuts lead for retractable pencil again.So not only lose time, and plumbous material of waste and timber.
The purpose of this utility model is at the problems referred to above, and a kind of polygonal cylindricality lead for retractable pencil pencil is provided.This pencil only need be cut penholder, and lead for retractable pencil is non-sharpenning, therefore can save timber and plumbous material, and the quality time of saving the user.
The purpose of this utility model adopts following technical proposals to realize, that is:
Polygonal cylindricality lead for retractable pencil pencil is made of penholder and polygonal cylindricality lead for retractable pencil, and the centre bore of penholder is a triangle cylindricality lead for retractable pencil through hole, and polygonal cylindricality lead for retractable pencil is a triangle cylindricality lead for retractable pencil, and triangle cylindricality lead for retractable pencil is arranged in the triangle cylindricality lead for retractable pencil through hole of penholder.
The profile of penholder can be triangle cylindricality, cylindrical or hexagonal cylindricality etc.
Triangle cylindricality lead for retractable pencil pencil in use, only need be cut penholder, and lead for retractable pencil is non-sharpenning, because three angles of lead for retractable pencil promptly are three points, three points use when writing, and the lead for retractable pencil mid portion has become point again.Therefore this pencil novel structure not only is easy to use, and can saves plumbous material, timber and user's time.
Fig. 1 is the structural representation of a kind of embodiment of the present utility model, and Fig. 2 is a triangle cylindricality lead for retractable pencil structural representation.The utility model is described in further detail below in conjunction with accompanying drawing.
Polygonal cylindricality lead for retractable pencil pencil is made of penholder 1 and lead for retractable pencil 2.Penholder 1 is a triangle cylindricality penholder, and lead for retractable pencil 2 is a triangle cylindricality lead for retractable pencil.The centre bore of triangle cylindricality penholder 1 is a triangle cylindricality lead for retractable pencil through hole 3, and triangle cylindricality lead for retractable pencil 2 is arranged in the triangle cylindricality lead for retractable pencil through hole 3, and triangle cylindricality lead for retractable pencil 2 closely cooperates with triangle cylindricality lead for retractable pencil through hole 3.
Claims (2)
1, polygonal cylindricality lead for retractable pencil pencil, constitute by penholder (1) and lead for retractable pencil (2), it is characterized in that described penholder (1) has triangle cylindricality lead for retractable pencil through hole (3), described lead for retractable pencil (2) is a triangle cylindricality lead for retractable pencil, this triangle cylindricality lead for retractable pencil is arranged in the triangle cylindricality lead for retractable pencil through hole (3) of penholder (1), and closely cooperates with triangle cylindricality lead for retractable pencil through hole (3).
2, polygonal cylindricality lead for retractable pencil pencil according to claim 1, the exterior cylindrical that it is characterized in that described penholder (1) is the triangle cylindricality, also can be cylindrical or the hexagonal cylindricality.
