Abstract

The utility model discloses a rotary guide extension penholder, which comprises a pen tail-cap rotary body, a guide penholder, a guide extension body and a pen point connecting piece. The penholder ischaracterized in that an annular wedge-shaped pen tail-cap rotary body projection and an annular pen tail cap rotary convex cylinder are respectively processed on the outer side wall at the middle part and the inner side wall at the lower part of the pen tail-cap rotary body; an annular guide penholder protrusion is processed on the inner side wall at the upper part of the guide penholder; an annular extension body outer thread and a guide extension body inner thread are respectively processed on the outer side wall at the middle-upper part and the inner side wall at the lower part of the guide extension body; a pen point connecting piece outer thread is processed on the outer side wall at the upper part of the pen point connecting piece; the shape of the cross section of the inner side wall at the middle-lower part of the guide penholder is an guide penholder inner hexagon; and the shape of the cross section of the outer side wall at the lower part of the guide extension body is a guide extension body outer hexagon. The utility model has the advantages that the pen core can be retracted into the guide penholder, printing ink or ink evaporation is reduced or slowed, and the rewriting is more convenient.

Description

The rotary guiding penholder that stretches

Technical field

The utility model relates to stationery, especially relates to the flexible penholder of a kind of rotary guiding.

Background technology

Present water-color paintbrush all is made up of a tail cap, penholder, written connector, pen core and the pen cap, tail cap, penholder, written connector and pen core maintain static, because pen core is printing ink or ink, intact note put the pen cap after the user was everlasting and uses, nib exposed in the air after a period of time, printing ink in the pen core or ink will become dry fast, write very inconvenience once more.

Summary of the invention

The purpose of this utility model be to provide a kind of can with in the pen core indentation guiding penholder, reduce or slow down the evaporation of printing ink in the nib or ink, the flexible penholder of book rotary guiding more convenient, simple in structure, handling ease once more.

The purpose of this utility model is achieved in that the utility model is by a tail cap rotary body, the guiding penholder, guiding extrusome and written connector are formed, feature is to be processed with a ring-type wedge shape tail cap rotary body projection on a middle part lateral wall of tail cap rotary body, on a lower inside wall of tail cap rotary body, be processed with a ring-type tail cap rotary body projection, on the upper inner wall of guiding penholder, be processed with the ring-type guiding penholder projection that cooperates with a ring-type wedge shape tail cap rotary body projection, the guiding extrusome is a hollow tubular, on the middle and upper part lateral wall of guiding extrusome, be processed with and the ring-type ring-type that tail cap rotary body projection cooperates a guiding extrusome external screw thread, on the lower inside wall of guiding extrusome, be processed with guiding extrusome internal thread, on the upper outside wall of written connector, be processed with and the written connector external screw thread of the extrusome screw-internal thread fit that leads; The shape of cross section of the middle and lower part madial wall of guiding penholder has been the interior hexagon of the guiding penholder of positioning and guiding effect, and the shape of cross section of the bottom lateral wall of guiding extrusome is the outer hexagon of guiding extrusome that cooperates with hexagon in the guiding penholder.

On a top outer wall of tail cap rotary body, evenly be processed with anti-skidding raised line.

The external diameter of the shade at tail cap rotary body top is slightly larger than the internal diameter at guiding penholder top.

The utility model is by a tail cap rotary body, the guiding penholder, guiding extrusome and written connector are formed, elder generation is with in the ring-type guiding extrusome external screw thread on the middle and upper part lateral wall of the tail cap rotary body projection screw-in guiding extrusome of the ring-type on the lower inside wall of tail cap rotary body during installation, insert a tail cap rotary body and guiding extrusome in the guiding penholder together downwards again, ring-type wedge shape on a middle part lateral wall of a tail cap rotary body tail cap rotary body projection snaps in the ring-type guiding penholder projection of the upper inner wall of guiding penholder downwards, a tail cap rotary body and guiding extrusome can not be made progress again to be dialled, and this moment, tail cap rotary body top just in time is seated in the top of guiding penholder again, bottom end opening from the guiding extrusome upwards inserts pen core to an extrusome and the tail cap a rotating body of leading then, again the written connector on the upper outside wall of written connector is screwed into the guiding extrusome the lower inside wall on guiding extrusome internal thread in and screw, put the pen cap at last and can install one-pen.Be rotated counterclockwise a tail cap rotary body, ring-type tail cap rotary body projection on the lower inside wall of tail cap rotary body is the rotation of the guiding of the ring-type on the middle and upper part lateral wall of guiding extrusome extrusome external screw thread just, because the shape of cross section of the bottom lateral wall of the shape of cross section of the middle and lower part madial wall of guiding penholder and guiding extrusome is hexagon, play location and guide effect, therefore, guiding penholder and guiding extrusome do not rotate, but the guiding extrusome can move on the guiding penholder, in guiding extrusome and written connector indentation guiding penholder; In contrast, a tail cap rotary body turns clockwise, ring-type tail cap rotary body projection on the lower inside wall of tail cap rotary body is the rotation of the guiding of the ring-type on the middle and upper part lateral wall of guiding extrusome extrusome external screw thread just, guiding extrusome and written connector do not rotate, but the guiding extrusome can move down along the guiding penholder, stretches out the guiding penholder until written connector and guiding extrusome.Therefore, the utlity model has can with in the pen core indentation guiding penholder, reduce or slow down the evaporation of printing ink in the nib or ink, write advantage more convenient, simple in structure, handling ease once more.
