Description

A kind of multifunctional pen

Technical field

The invention belongs to the teaching appliance field, be specifically related to a kind of multifunctional pen.

Background technology

Chalk, teacher's pointer and generating laser are teaching appliances commonly used at present, but carry this three samples article on class simultaneously at every turn, often make the people feel inconvenience, and the teacher's pointer volume is bigger; Generating laser is more easily forgotten owing to be not all need use at every turn; Simultaneously chalk exists hand easily to be stained with ash, and is unhygienic, and frangibility such as can not make full use of at problem.

The utility model content

The utility model is exactly for fear of above deficiency, and providing a kind of is pen core with the chalk, gathers the multifunctional pen of teacher's pointer and generating laser function simultaneously.

Goal of the invention of the present utility model can realize by following technological means:

A kind of multifunctional pen comprises special-purpose chalk of pen container, retractor device, the pen cap and pen container and blackboard eraser; Wherein the pen container blind end connects retractor device, and openend connects the pen cap.

Pen container comprises penholder, nib, swing arm and knob; Wherein the penholder inner chamber is provided with rib, a side outer wall fixed slot, and a side outer wall indicates scale; Blackboard eraser inserts the pen container slot; Swing arm is connected with knob, and swing arm inserts its inner chamber from penholder one end, and is connected with penholder by knob, and the penholder other end connects nib.

Retractor device is identical by external form, and the collar intussusception that size is successively decreased forms.

The pen cap comprises sleeve, generating laser, battery case, big spring, promotion button, little spring and by press button; Sleeve one end has a hole, has two holes on the same straight line of a side outer wall; Promote button one end and be furnished with barb, a side is shifting block fixedly, the fixing hook of dialling of opposite side; Is furnished with barb by press button one side; Generating laser, battery case, big spring, promotion button and little spring are positioned at barrel bore, and generating laser is positioned at sleeve perforate end, and big spring is positioned at the sleeve other end, and the anodal output current of battery case is through generating laser and spring input battery case negative pole; Promote button do not join barbed end by little spring and barrel bore not the perforate end is connected, promote the button shifting block and protrude from sleeve outer wall by hole under the sleeve outer wall, the promotion button is dialled hook insertion big spring; Be positioned at sleeve outer wall by press button, do not join barbed end by press button and be fixed on the outer wall of sleeve perforate end, its barb is positioned at top, hole on the sleeve outer wall.

Pen container, retractor device, pen cap profile are triangle.

Chalk one end perforate, the outer wall fluting.

This pen is pen core with the chalk, has avoided hand to contact with the direct of chalk, and is convenient and healthy; The while chalk stretches out the length of penholder can be regulated by swing arm and knob, can prevent that chalk from fractureing, and can make full use of chalk again.The pen container blind end connects retractor device, if elongate retractor device, this pen is used as teacher's pointer.Generating laser is installed in the pen cap, can be made this emission laser.

Fig. 4 is a pen cap structural representation.

The specific embodiment

See figures.1.and.2:

The utility model is that the using method of pen core is as follows with chalk 3:

Remove nib 12, because the perforate of chalk 3 one ends institute is inner bolt hole, swing arm 13 has screw thread, earlier chalk 3 and swing arm 13 is connected by screw thread rotation during use, then chalk 3 is passed through its groove along penholder 11 inner chamber ribs 15 insertion penholders 11.Rotation knob 14 during use, screw thread produce along the power of penholder 11 vertical direction and the power of horizontal direction chalk 3, and penholder 11 inner chamber ribs 15 balance the power of chalk 3 horizontal directions, make chalk 3 stretch out penholder 11, and adjustable length.

The utility model uses the method for common pen core as follows:

The nib 12 of outwarding winding is inserted penholder 11 with pen core, screws nib again and 12 gets final product.

With reference to figure Fig. 1 and Fig. 3, elongate retractor device 4, because the existence of cover interannular frictional force is overlapped interannular and is difficult for retraction, then the pen of elongation can be used as the teacher's pointer use.

With reference to Fig. 1 and Fig. 4, promote to promote button 55 and hook lower edge, hole on sleeve 51 outer walls until its barb 551, big spring 54 was pushed button and dialled hook 553 and drive and contact with battery case 53 negative poles this moment, and generating laser 52 is switched on, and launched laser by sleeve 51 perforate ends.Press lower sleeve 51 outer walls when not using by press button 57, the barb 551 by its barb 571 effect promotion buttons 55 makes it break away from lower edge, hole on the outer wall, again because the effect of little spring 56 restores to the original state promotion button 55.
