Abstract

The utility model relates to a pen capable of correcting wrong words, which is composed of a pen head, a pen holder, a pen cap and a pen core of solid correction agent, wherein, all the parts are connected together in an insertion mode; the circumference of the rear end of the pen head is distributed with three equispaced retraction grooves; a trapezoid boss is arranged at the inner front part of the pen holder, and compresses the rear end of the pen to lock the pen core when the pen head is inserted in the pen holder. With less and moderate locking force, the pen core can not be broken by locking and can be ejected in a stepping mode. The utility model has the advantages of simple structure, effective protection of the pen core of solid correction agent, convenience and practicability.

Description

Solid revised pen

The utility model relates to a kind of pen of revising wrongly written character.

The instrument of common in the market correction wrongly written character is bottled opaquing fluid.Because opaquing fluid has easy obstruction, shortcoming such as need to rewrite after the solvent evaporates serous coat drying during correction.So occurred solid correction agent in recent years, as the flat 3-175097 of Japan, flat 2-97571, clear and 63-237999 is clear and patent such as 63-238000.This solid correction agent generally all adopts wax, Chinese white, inorganic filler, adhesive and auxiliary agent to form.Compare with liquid correction agent, can not write again immediately after can not blocking up, leaking, revise.Can make the product of different shape, above patent has been discussed the prescription and the production of solid correction agent, has mentioned wax crayon shape pen core is made in solid correction agent being packed into and using in the lip pencil shell.But all do not provide the shell that a kind of suitable solid correction agent pen core uses.Existing various pen all is for specific pen core designs, as propelling pencil, and the knockout of pulsing, but the intensity of pencil-lead is much higher than solid correction agent pen core, as adopt ready-made propelling pencil structure, and solid correction agent pen core fractures easily, and influence is used.

The purpose of this utility model provides can the pulse solid correction pen of knockout of a kind of pen core that can not fracture simple in structure.

The utility model is made up of penholder, nib, the cap for brush three parts, each several part does not have screw thread and adopts insertion to connect, the nib tail end has three retraction slots, be used for penholder in a trapezoid boss lock pen core when nib is compressed in the penholder front end, the penholder inner convex platform compresses written tail end pen core is locked, coupling mechanism force guarantees that pen core does not endwisely slip, and also can not lock disconnected pen core simultaneously.Written coupling mechanism force disappears, pen core arbitrarily endwisely slips as firmly dialling, and can regulate pen core and expose written length this moment.

Further describe the utility model below in conjunction with accompanying drawing.

Accompanying drawing is a profile of the present utility model, and the each several part implication is as follows among the figure:

The 1-cap for brush; 2-solid correction agent pen core; The 3-nib; The 4-retraction slot; The 5-trapezoid boss; The 6-penholder;

Pen core (2) inserts in the nib (3), symmetry uniform three grooves that contract (4) on the tail end circumference of nib (3), will with the nib (3) of pen core (2) insert penholder (6) in compress, the tail end of the interior trapezoid boss of penholder (6) (5) compression nib (3), the tail end of nib (3) shrinks locks pen core (2), and nib (3) external diameter is that the big frictional force of interference fit formation stops the relative slip of its faying face generation to guarantee to lock reliable and stable with penholder (6) internal diameter.When exposing nib (3) part pen core (2) owing to using when shortening, firmly extract nib (3), coupling mechanism force disappears, with pen core (2) release nib (3) some, compress in the insertion penholder (6), realize the stepping knockout like this.

The utility model is simple in structure, and is easy to manufacture, all adopts to insert between the each several part to connect, and coupling mechanism force is of moderate size, not easily broken core.

Claims

1, a kind of solid correction pen includes penholder, nib, the cap for brush, and solid correction agent pen core is characterized in that three retraction slots of written tail end garden Zhou Junbu, and there is a trapezoid boss front portion in the penholder, and nib is inserted in the penholder, and trapezoid boss compresses written tail end locking pen core;

2, solid correction pen as claimed in claim 1 is characterized in that nib (3) external diameter and its tolerance fit of the anterior internal diameter of penholder (6) are interference fit.
