Description

Multi-functional permanent Wood-bar pencil

The utility model relates to the teaching of culture technical field, specifically a kind of pencil that is used to write and draws.

Existing Wood-bar pencil is made up of penholder and pen core secure bond, and pen core can not extend, and will often cut out nib during use, and is convenient inadequately, and rod is the same with pen core can only use once, and the pen core utilization rate is not high, and the penholder waste is big; Some propelling pencils, pen core are very thin, only are applicable to some specific uses, are not easy to people and generally use.

The purpose that this practicality is new is to provide a kind of flexible, replenishes pen core and the pen core of changing different colours and different HB values, can make student's chi, and compasses use, and has the pencil of simple and easy calendar.

The purpose of this utility model promotes piston, on-slip circle and compasses head by pencil shaft, pencil-lead, erasing rubber and forms.

Pencil-lead and promotion piston are sleeved in the interior reservoir hole of penholder from the bottom up successively, and the position of on-slip circle is enclosed within outside the penholder on the promotion piston, the penholder that timber or plastics are made, and the top of a side has the rectangle hole slot of a width less than the pen core diameter; Long measure is carved with on the opposite side surface of penholder, promotes piston to be and the isodiametric Cylinder of pen core, is connected with piston isometricly, and thickness is less than the brake(-holder) block of hole slot width, and the hole slot that brake(-holder) block passes on the penholder from the penholder center stretches out outside the penholder.

Pencil-lead comprises the multiple pen core of different colours, different HB values.

The utility model can extend and additional pen core, can also do student's chi, compasses use, all right displaying calendar; Its function is many, use, easy to carry; The penholder no consumption can be saved timber.

Implementing legend below in conjunction with the utility model elaborates.

Embodiment 1

As Fig. 1, Fig. 2, shown in Figure 5, will promote piston 8 on-slip circles 2 erasing rubbers 1, be sleeved on the top of penholder 4 successively from the upper end, from the most advanced and sophisticated aperture of penholder 4 pencil-lead is pushed in the penholder 4; In the reservoir hole 7, the upper end of pen core contacts with piston 8, and on-slip circle 2 is near on the brake(-holder) block 3.Pencil core print sharpening on the sand paper 16 of compasses head 9 one sides, just can write.When the pen core exposed parts exhausts, stir brake(-holder) block 3 downwards, pencil-lead is released by piston 8, stretch out suitable length after, stop to stir, on-slip circle 2 is moved to brake(-holder) block 3 contact then, continue again to use.Pen core 6 in the penholder consumes to bottom line, in the time of can not releasing, can replenish pen core from the nib hole Qian.Also can release original pen core as required, change the pen core of other different colours or different HB values.

Embodiment 2

As shown in Figure 6, from penholder back off erasing rubber and on-slip circle 2, contrast long measure 19 is made ruler and is used.

Embodiment 3

As Fig. 4, shown in Figure 6: compasses head 9 is trapezoidal can, and 12 two waists and upper base are the right angle flanging at the bottom of the box, and there is turning handle 11 on last base, and there is circular hole at the center; There is screw at lid 15 centers, and in 12, screw rod 13 passes the circular hole at the bottom of the box at the bottom of the corresponding built-in box, and the screw of the screw thread of screw rod end and lid 15 screws; Insert two pencils 4 that withdraw from erasing rubber 1 and on-slip circle 2 from the trapezoidal Direction box mouth 14 of going to the bottom, wherein one pen core point changes draw point 10 into, tightens screw rod 13, forms compasses.

Embodiment 4

As shown in Figure 1, on-slip circle 2 outsides are printed on big order numeral of week 7, and a certain numeral facing to brake(-holder) block 3, is promptly represented the date on the same day.
