Abstract

A novel pen holder comprises a main pen holder, a front pen holder, a pen cap, a blocking piece and a screw spring, wherein the main pen holder is a barrel whose bottom is provided with a screw thread through-hole, the opening part of the barrel is provided with an outside screw segment; the center parts of the small cylinder segment and the big cylinder segment of the front holder respectively are a column chamber D and a column chamber C, the internal circumstance surface of the column chamber C is provided with an inside screw segment which is matched by screwing with the outside screw segment of the main pen holder, and the external circumstance surface of the small cylinder segment is provided with an outside screw segment; the external circumstance of the small cylinder segment of the pen cap is provided with an outside screw segment which is matched by screwing with the screw thread through-hole of the main pen holder, and the circumstance surface of a column chamber F of the big cylinder segment center part is provided with an inside screw segment which is matched by screwing with the outside screw segment of the front pen holder. The blocking piece is arranged at the internal bottom of the main pen holder, and the tail part of the pen core is pressed on the blocking piece by the elastic force of the screw spring. The utility model is characterized in that only when the outside screw of the pen cap gets through the screwing match with the screw thread through-hole of the main pen holder, the pen point can enter into writing, thereby achieve the purpose of not loss the pen cap.

Description

A kind of novel penholder

Affiliated technical field

The utility model relates to a kind of penholder, especially is difficult for losing a kind of penholder of the cap for brush.

Background technology

The people that use gel ink pen at present are a lot, and reason is that such application is convenient, low price.But owing to its cap for brush is often lost, and after the pen core time that is not with the cap for brush was slightly long, its nib just was difficult to write word again.In order to solve this inconvenience, the present invention takes another thinking: with the built-in state of nib with expose write state with the cap for brush combines, that is: when not having the booster action of the cap for brush, the head of pen core does not expose, so can not write yet.Like this, people just can not forget the cap for brush, thereby have solved the problem of losing of the cap for brush.Find no the invention of identical structure by retrieval.

Summary of the invention

The objective of the invention is: the problem of losing that solves its cap for brush of gel ink pen.

A kind of novel penholder, it is made up of main pen arm (1), preceding penholder (2), the cap for brush (3), barrier sheet (4), helical spring (5); Main pen arm (1) has the cylindrical body of a screwed hole (12) for the center of its bottom, is provided with external thread section (11) at the openend of cylindrical body;

The profile of preceding penholder (2) is the formation of concentricity line by roundlet shell of column (21) and great circle shell of column (22), the centre of corresponding roundlet shell of column (21) is cylinder chamber D, outer peripheral face at roundlet shell of column (21) is provided with external thread section (24), the centre of corresponding great circle shell of column (22) is cylinder chamber C, inner peripheral surface at cylinder chamber C is provided with and can revolves the internal thread segment (23) of joining with its external thread section of main pen arm (1) (11), and cylinder chamber C and cylinder chamber D are UNICOM's shape; The profile of the cap for brush (3) is the formation of concentricity line by roundlet shell of column (32) and great circle shell of column (31), the periphery of roundlet shell of column (32) is provided with and can revolves the external thread section (34) of joining with its tapped through hole of main pen arm (1) (12), its centre of great circle shell of column (31) is cylinder chamber F, is provided with and can revolves the internal thread segment (33) of joining with its external thread section of preceding penholder (2) (24) at the inner peripheral surface of cylinder chamber F; Barrier sheet (4) places its place, bottom of main pen arm (1), and the effect of helical spring (5) is that its afterbody of pen core (6) that will select for use is pressed on the barrier sheet (4).

In above-mentioned invention, owing to have only the external thread section (34) just can be with barrier sheet (4), preceding the pushing away of pen core (6) by joining with revolving of its tapped through hole of main pen arm (1) (12) when the cap for brush (3), the nib that is pushed out just can be write for people, people can not leave the cap for brush (3) main pen arm (1) for this reason, reach the beneficial effect of not losing the cap for brush (3) like this.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation.

Fig. 2 is the structural representation of main pen arm.

Fig. 3 is the structural representation of preceding penholder.

Fig. 4 is the structural representation of the cap for brush.

The utility model schematic diagram that Fig. 5 can write word state for pen core is in.

Among each figure, 1, main pen arm, 11, external thread section, 12, screwed hole, 2, preceding penholder, 21, the roundlet shell of column, 22, great circle shell of column, 23, internal thread segment, 24, external thread section, 3, the cap for brush, 31, the great circle shell of column, 32, the roundlet shell of column, 33, internal thread segment, 34, external thread section, 4, barrier sheet, 5, helical spring, 6, pen core.

The specific embodiment

The utility model as shown in Figure 1 is made up of main pen arm (1), preceding penholder (2), the cap for brush (3), barrier sheet (4), helical spring (5); And the internal thread segment (33) that the internal thread segment (23) of its external thread section of main pen arm (1) (11) and preceding penholder (2) is the external thread section (24) of the joining relation of revolving, preceding penholder (2) and the cap for brush (3) is revolves the relation of joining, is nested with at the helical spring (5) of pen core (6) the front end afterbody with pen core (6) and is pressed on the barrier sheet (4).When people need write with a pen word, at first the cap for brush (3) is screwed off on preceding penholder (2), then in the tapped through hole (12) with its external thread section of the cap for brush (3) (34) precession main pen arm (1).In the process of constantly precession, stressed barrier sheet (4) will promote moving of pen core (6), and the nib of built-in shape just can be in the outer dewiness that writes so originally, as shown in Figure 5.

Since this pen can write closely bound up with combining of the same main pen arm of the cap for brush (3) (1), so people the existence of the cap for brush (3) is paid attention to unusually, so the cap for brush (3) is lost never again easily.

Claims

1, a kind of novel penholder, it is made up of main pen arm, preceding penholder, the cap for brush, barrier sheet, helical spring; It is characterized in that: main pen arm (1) is threaded the barrel of through hole (12) for the center of its bottom; The periphery of its roundlet shell of column (32) of the cap for brush (3) is provided with and can revolves the external thread section (34) of joining with its screwed hole of main pen arm (1) logical (12).
