The purpose of this utility model is achieved in that a kind of pen of adjustable in length, comprises nib, a body and a tail, and its improvements are: a body by one the joint more than mutually the penholder of socket form;

Described penholder is divided into two parts, and a part is the Nut pole that two ends have internal thread, and another part is that two ends are provided with and match with the Nut pole internal thread and the shank of bolt of hollow;

A described nib and a tail be positioned at penholder one side be provided with can with the bolt section of penholder Nut pole screw-internal thread fit;

It comprises that also penholder prolongs pipe, prolongs in the pipe to be provided with baffle plate, and its both ends open is provided with the internal thread that matches with a shank of bolt and a tail outward.

Than a common structure, the beneficial effects of the utility model are by the threaded engagement on the penholder bolts and nuts section, thereby reach the purpose of a free adjustment height degree, and be equipped with penholder prolongation pipe, can adjust a body to self comfortable length according to the personal like.

[description of drawings]

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

Fig. 1 is a cross-sectional view of the present utility model.

[specific embodiment]

Referring to figure one, a kind of pen of adjustable in length, comprise nib 1, be used to adjust length, the penholder of socket is divided into two parts mutually, a part has internal thread 112 Nut poles 2 for two ends, another part is that two ends are provided with the external screw thread 111 that matches with Nut pole 2 internal threads 112 and the shank of bolt 3 of hollow, after tail 5 is placed in penholder, can be equipped with a penholder in addition in addition and prolong pipe 4, be provided with baffle plate 113 in this prolongation pipe 4, its both ends open is provided with the internal thread 112 that matches with a shank of bolt 3 and a tail 5.Described written 1 is positioned at penholder one side with a tail 5 is provided with the bolt section 111 that can cooperate with its Nut pole 2 internal threads 112.

Described nib comprise front end and can with the bolt section of penholder Nut pole screw-internal thread fit, described tail comprise can with the bolt section of penholder Nut pole screw-internal thread fit and the cap for brush thereafter.

During actual the use, carry out the length collocation to adapt to used length for core by penholder Nut pole 2 and the shank of bolt 3 that is equipped with different size.After the feature of the pen core in considering daily life, the length of its pen core is common to be 130mm or two kinds of specifications of 99mm, so locate that penholder Nut pole 2 length standards are set at 15mm in the specific embodiment, the common 6-7mm of its internal thread, penholder Nut pole 2 every joints of Pei Beiing increase 1mm successively thereafter; Penholder shank of bolt 3 is removed the outer middle effective length datum length of bolts at two ends and is made as 16mm, and its hollow hole directly is 5mm, and the every joint of effective length of the shank of bolt 3 of other outfits increases 1mm successively.Penholder prolongs pipe 4 long 28mm, and its both ends open degree of depth then is respectively 13.5mm and 14mm.Need be equipped with two joint penholder Nut poles and a joint penholder shank of bolt during use at least, save Nut pole and shank of bolt can be finished after this needing overtime only need dispose one successively again.4 of penholder prolongation pipes are used for using when the user wishes that trace is adjusted penholder length, the feel when using by the counterweight improvement pen that changes penholder integral body.
