Abstract

The utility model relates to an auxiliary pen cap for chalk or pencil, which includes a hollowed pen cap (3), a pen holder nut (1) is movably connected to the bottom end of the pen cap, inside the pen holder nut (1) there is an inner screw hole; a T- shaped pen holder (2) is set inside the pen cap, the bottom end of the T- shaped pen holder is a screw stick; a clamp nut (5) is transversely and movably set on the top end of the pen cap, inside the clamp nut there is an inner screw hole; a clamp stick (4) is transversely and movably set across pen cap wall, the clamp end of the clamp stick is inside the pen cap, the other end is across the pen cap wall and set inside the inner screw hole and has matching screw. The present utility model is simple in structure, low in cost, and with the cooperation of pen cap and the rotation adjustment mechanism, clamp and scalability of chalk or pencil can be effectively implemented, thus achieving the effect of natural clamp and easy use, and satisfying the request that the modern society is a conscious society.

Description

The auxiliary pen cap

Technical field

The utility model relates to a kind of auxiliary extension fixture, specifically is a kind of auxiliary pen cap that is used for chalk or pencil.

Background technology

Chalk is as teacher's teaching writing instrument, pencil is as people's especially pupil operation writing implement, though can satisfy the daily life requirement, but because frequency of using and consume are greatly, and chalk or pencil are using (the about 15mm of chalk when a bit of, the about 50mm of pencil), often is inconvenient to be dropped, causes waste because of grasping.

Patent 02243914.5 discloses the auxiliary pen cap of a kind of prolonged type, constituted by the pen cap that can be nested with pencil and a branch of circle, can prolong the length of pencil effectively, make things convenient for grasping to write, can be with the pencil that runs low, continued again after sheathed to use, economizing on resources, and be nested with conveniently, easy to carry, but it can only be used on the thinner pencil of a body, and the scope of application is less, and can only once use behind sheathed pencil, only has the clamping function, do not possess Telescopic, use inconvenience, can not satisfy people's requirement better.

The utility model content

The purpose of this utility model is to provide a kind of auxiliary pen cap at the deficiencies in the prior art, adopt the pen cap to match with adjustable diameter and screw adjusting mechanism, can realize the clamping of chalk or pencil and flexible effectively, reach natural, the easy to use effect of grasping, satisfying modern society is the requirement of a conservation-minded society.

The technical scheme that the utility model adopted:

A kind of auxiliary pen cap comprises the pen cap of hollow, flexibly connects a pen holder nut in the bottom of the pen cap, and a pen holder nut can arbitrarily be rotated, and the inside of pen holder nut is provided with internal thread hole; At the pen cap internal activity holder of T type pen is set, the bottom of T type pen holder for the internal thread hole of the pen holder nut threaded rod that is complementary, when pen with rotary holder nut, under the effect of screw thread, make the holder of T type pen rise or descend, realizes stretching of stand-by pen (chalk or pencil); Horizontal activity is provided with the clamping nut in the upper end of the pen cap, and the clamping nut can arbitrarily be rotated, and the inside of clamping nut is provided with internal thread hole; Pass the horizontal activity of pen sleeve wall supporting rod is set, supporting rod can freely be stretched on pen sleeve wall, the bare terminal end of supporting rod is in the pen cap, the other end passes pen sleeve wall and places in the internal thread hole of clamping nut and the screw thread that is complementary is arranged, when rotating the clamping nut, under the effect of screw thread, make the supporting rod move left and right, stand-by pen can be clamped.During use, stand-by pen is put into from porch, pen cap top, elder generation's pen with rotary holder nut is regulated T type pen holder height to determine the overhang of stand-by pen, and rotating the clamping nut then, that supporting rod is blocked stand-by pen is fixing, thereby whole stand-by pen is fixed in the pen cap so that use.

The bare terminal end of described supporting rod is an arc-shaped structure, can more stand-by pen be blocked.

Vertical slide rail is set in the described pen cap, can limits the rotation of T type pen holder and make it to move up and down.

The utility model is simple in structure, and cost is low, adopts the pen cap to match with adjustable diameter and screw adjusting mechanism, can realize the clamping of chalk or pencil and flexible effectively, reaches grasping nature, effect easy to use, and satisfying modern society is the requirement of individual conservation-minded society.

Among the figure: 1, pen holder nut; 2, T type pen holder; 3, the pen cap; 4, supporting rod; 5, clamping nut.

Description of drawings

In the structure shown in the figure, the utility model comprises the pen cap 3 of hollow, flexibly connects pen holder nut 1 in the bottom of the pen cap, and the inside of pen holder nut 1 is provided with internal thread hole; At the pen cap internal activity T type pen holder 2 is set, the bottom of T type pen holder for the internal thread hole of the pen holder nut threaded rod that is complementary; Horizontal activity is provided with clamping nut 5 in the upper end of the pen cap, and the inside of clamping nut is provided with internal thread hole; Pass the horizontal activity of pen sleeve wall supporting rod 4 is set, the bare terminal end of supporting rod is in the pen cap, and the other end passes pen sleeve wall and places in the internal thread hole of clamping nut and the screw thread that is complementary is arranged.During use, stand-by pen is put into from porch, pen cap top, elder generation's pen with rotary holder nut is regulated T type pen holder height to determine the overhang of stand-by pen, and rotating the clamping nut then, that supporting rod is blocked stand-by pen is fixing, thereby whole stand-by pen is fixed in the pen cap so that use.

Claims
