Abstract

The utility model discloses a spring pen, comprising a pen container and a pen head arranged in the pen container; the front end of the pen head is butt-jointed with one end of a spring; the front end of the pen head is sheathed with a pen head cap which can slide thereon; the pen head cap is provided with a shaft shoulder and is butt-jointed with the other end of the spring; the front end of the pen head cap is provided with a rubber cover; and a torsion spring is arranged between the rubber cover and the pen head cap. By adopting the technical scheme, the spring pen has the advantages of: having convenient production and reasonable structure, being capable of fully guaranteeing the sealing of the spring and the pen head. As the pen head cap is not needed, when in use, the open of the spring pen can be operated by one hand and the probability that the pen can not be used due to the losing of the pen head cap can be avoided.

Description

A kind of spring pen

Technical field

The utility model relates to pen, more specifically says, it relates to a kind of spring pen.

Background technology

The spring pen of prior art mostly is and has the pen cap, needs plug during use.The effect of the pen cap is to prevent that nib from polluting and the volatilization of fluorescence liquid.In use, the spring pen of this band pen cap needs one to hold penholder and extract the pen cap on the other hand and could use, if one-handed performance is very inconvenient.And the pen cap is lost easily, causes normally practicality of pen.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and both can effectively seal nib, does not need bimanualness again, and need not the spring pen of the pen cap.

The purpose of this utility model is achieved through the following technical solutions.This spring pen, comprise pen container and be located at the interior nib of pen container, one end of nib front end and spring is apical grafting mutually, described written front end sleeve is provided with the pen point casing that can slide thereon, pen point casing be provided with the shaft shoulder and with the other end of spring apical grafting mutually, the pen point casing front end is provided with serum cap, is provided with torsion spring between serum cap and the pen point casing.

One end of described torsion spring is arranged on the serum cap, and the other end is arranged on the shaft shoulder.

Described written front end is fixedly connected with the spring back seat, and spring one end and spring back seat be apical grafting mutually, and the other end and the shaft shoulder be apical grafting mutually.

Part and button cover are changeed after being provided with and changeing part, second pen container behind first pen container that matches in described written rear end.

The effect that the utility model is useful: owing to adopt technique scheme, a kind of spring pen of the present utility model, easily manufactured, rational in infrastructure, can fully guarantee the sealing of spring nib.Because need not the pen cap, the unlatching of one-hand operation pen during use, and stopped to cause the possibility that can't use because of losing of the pen cap.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram;

Description of reference numerals: 1 pen container; 2 serum caps; 3 torsion springs; 4 pen point casings; 5 springs; 6 spring back seats; 7 nibs; Change part behind 8 first pen containers; Change part behind 9 second pen containers; 10 button covers; 11 shaft shoulders.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims qualification.

Referring to Fig. 1 to 2, a kind of spring pen of Jie Shaoing generally is used for e-Pointer or water-color paintbrush etc. here, yet should know that the utility model also can be used for other structure.This a kind of spring pen, comprise pen container 1 and be located at nib 7 in the pen container 1, nib 7 front ends also are arranged with the pen point casing 4 that can slide thereon, pen point casing 4 be provided with the shaft shoulder 11 and with spring 5 front ends apical grafting mutually, spring 5 rear ends and spring back seat 6 apical graftings, spring back seat 6 is fixed on the nib 7, and pen point casing 4 front ends are stamped serum cap 2, and serum cap 2 is connected by torsion spring 3 with pen point casing 4; One end of torsion spring 3 is arranged on the serum cap 2, and the other end is arranged on the shaft shoulder 11.Serum cap 2 and pen point casing 4 clamp by torsion spring 3.Part 9 and button cover 10 are changeed after being provided with and changeing part 8, second pen container behind first pen container that matches in nib 7 rear ends.

During use, the cover 10 that pushes button changes under the cooperation of part 9 after changeing part 8, second pen container behind first pen container, nib 7 serum caps 2 that back down on the pen point casing 4, torsion spring 3 and spring 5 produce certain elastic deformation, and just be exposed to outside the pen container 1 this moment written 7, just can write.When spring pen is write when finishing, push button once more and overlap 10, change under the cooperation of part 9 after changeing part 8, second pen container behind first pen container, nib 7 is by moving in the past pen container 1 of the elastic force of spring 5, and serum cap 2 covers pen point casing 4 at last again also thereupon by torsion spring 3 past swivel motions.Just be accommodated in pen container 1 fully and suffered this moment written 7.

In addition, written 7 rear ends of the present utility model are provided with to change behind first pen container that matches changes part 9 and button cover 10 behind part 8, second pen container and can also replace with other press device, as the various press devices of ball pen.
