A kind of many functional grouping pencils, including front end pen container, front end pen container are divided into top and bottom, top and bottom inwall Having has internal thread, and there are front end connection screw thread, top and bottom inner portion installation Pencil with 2B hardness and 2H pencils, Pencil with 2B hardness and 2H lead in bottom Pen is cylindric, and periphery is machined with external screw thread；Pencil external screw thread can be connected with front end pen container internal thread.

Preferably, pen container section in front end is hexagon.

Preferably, pen container both ends in front end are printed on 2B and 2H printed words respectively.

Preferably, the internal thread length 1cm of 2B ends and 2H ends inwall.

Preferably, pencil surface reach is equal to pencil length.

Preferably, nib exposes front end pen container 2cm after Pencil with 2B hardness and 2H pencil installations.

There is end connection screw thread end pen container, end pen container one end, there is endsocket internal thread on inwall.

Preferably, endsocket internal thread length is 1cm.

Preferably, endsocket one end open, one end closing.

Branch sleeve, branch sleeve both ends are machined with bush whorl with bush whorl, connected on bush whorl with end Screw thread cooperation is connect, is connected under bush whorl with front end connection screw thread.

Preferably, branch sleeve section is hexagon.

Preferably, length sleeve is more than 5cm.

A kind of many functional grouping pencils of the present utility model, prior art, which compares caused beneficial effect, is：

1) pencil of the different trades mark is combined, can random switching pencil board according to the actual requirements during operation Number, solve conventional different trade mark pencils and put together and hold confusing situation.

2) due to the presence of sleeve, pencil can also use as usual even if a seldom part is left, and improve resource Utilization ratio.

2) sleeve and pen container can play a protective role to the nib of sharpening when carrying, and prevent from fractureing.
