The setting of the utility model shell fragment, purpose are when adapter sleeve and shell fragment screw engagement, are the shell fragment pressurized of certain taper, urgent file bar, and the file bar then is fixed on one's body the pen.When the file bar shrinks when being hidden in body,, be convenient for carrying as the one-pen size; The file bar can extend the length that needs at any time, by the fastening location of adapter sleeve.When the wearing and tearing of file bar, only need to replace the file bar and get final product, needn't abandon whole file, economical and practical.

Now in conjunction with the accompanying drawings the utility model is further described:

Accompanying drawing 1 is the utility model structural representation;

State diagram when accompanying drawing 2 is the utility model contraction;

Cutaway view when accompanying drawing 3 is the utility model elongation.

As shown in Figure 1, the utility model is made up of a body 1, adapter sleeve 3 and file bar 4.Body 1 port is provided with shell fragment 2, and there is screw thread shell fragment 2 outer ends, and are certain taper, and oral area is narrow slightly, and file bar 4 is fixed on the body 1 by adapter sleeve 3.In the accompanying drawing, the 5th, pen clip can be sandwiched on the dress ornament.

As shown in Figure 2, file bar 4 shrinks and is hidden in the body 1, is fastened on the body 1 by adapter sleeve 3.

As shown in Figure 3, file bar 4 is nested with on a body 1, and adapter sleeve 3 is provided with internal thread 31, and the tapering of its internal diameter and shell fragment 2 coincide, when adapter sleeve 3 and shell fragment 2 screw engagement, and shell fragment 2 pressurizeds, urgent file bar 4 is fixed on the body 1 thereby will file bar 4.
