Abstract

The utility model provides a pen capable of drawing straight lines and angles. The pen comprises a pen barrel, a pointer sleeve, a folding pointer, a pen sleeve, a shaft sleeve, a rotating shaft and two rotating wheels. The pen barrel is perpendicularly fixed at the center of the pen sleeve and is perpendicular to a plane like a paper sheet and others where the lines are drawn. The upper middle side of the pen barrel is provided with scale marks in an engraved mode. The pointer sleeve which can rotate around the pen barrel is located below the scale marks, the pen barrel is sleeved with the pointer sleeve, enough friction force exists between the pointer sleeve and the pen barrel, and accuracy of an indicating angle is guaranteed during using. The scale marks on the pointer sleeve are engraved above the pointer sleeve and used for indicating the rotating angle of the pointer sleeve around the pen barrel. By means of the pen, the straight lines can be drawn conveniently and rapidly, the angles with corresponding degrees can also be drawn, and straightness of the straight lines drawn through the pen and accuracy of the angles drawn through the pen can be guaranteed. The pen is convenient to use, easy to operate, low in cost and wide in application.

Description

A kind of pen that can draw straight line and angle

Technical field

The utility model belongs to a kind of stationery, the especially a kind of pen that can draw straight line and angle.

Background technology

At present, people, when drawing straight line, are generally to have coordinated by while operating pen and ruler, and therefore the length of drawn straight line is subject to the impact of ruler length, and owing to being to operate simultaneously, in the setting-out process, working, some is loaded down with trivial details.In addition, when drawing angle, generally also need the use amount hornwork, so just make the operating procedure complexity, affect operating efficiency.

Summary of the invention

In order to overcome above difficulty, the utility model provides a kind of pen that can draw straight line and angle.

Basic technical scheme is: penholder is vertically fixed on the center of the pen cap, and perpendicular to the setting-out plane, as paper etc.Reticule is carved with in the middle top of penholder.There is a pointer cover that is enclosed within on penholder and can rotate around penholder reticule below, between pointer cover and penholder, enough frictional force is arranged, and while guaranteeing to use, the indication angle is accurate.The groove that pointer puts is engraved in pointer cover top, is used to refer to the angle that the pointer cover turns over around penholder.Collapsible pointer one end fixes on pointer by hinges fixing and puts, and be positioned at groove that pointer puts under, collapsible pointer is comprised of two joints, between two joints, can turn folding, and in used time not, can fold up and paste penholder and place, and has guaranteed easy to use.Two identical runners of diameter are fixed in rotating shaft, and can be with the rotating shaft synchronous rotary.The surface of runner uses the material very large with the paper coefficient of friction to make as rubber etc.Rotating shaft is inserted in axle sleeve, and between the length of axle sleeve and two runner inboards apart from identical, two runners can synchronously be rotated but can not transverse shifting on axle sleeve.Axle sleeve is fixed on pen cap below.

The beneficial effects of the utility model are: this device can break away from ruler and draw straight line, the length of drawn straight line can not be subjected to the long restriction of chi, and can draw easily the angle of respective angles, can guarantee the linearity of drawn straight line, the precision at angle, easy to use, simple to operate, with low cost, be widely used.

Four, accompanying drawing explanation

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is structural front view of the present utility model.

In figure: 1. penholder, 2. reticule, 3. pointer cover, the 4. groove that puts of pointer, 5. collapsible pointer, the 6. pen cap, 7. 8. runner (2), 9. axle sleeve, 10. rotating shaft of runner (1).

Fig. 2 is structure top view of the present utility model.

In figure: each label title is identical with Fig. 1.

Five, the specific embodiment

Be vertically fixed on the center of the pen cap 6 with reference to penholder 1 shown in Figure 1, and perpendicular to the setting-out plane, as paper etc.Reticule 2 is carved with in the middle top of penholder 1.Reticule 2 belows have one can, around the pointer cover 3 of penholder 1 rotation, between pointer cover 3 and penholder 1, enough frictional force be arranged.The groove 4 that pointer puts is engraved in pointer cover top.Collapsible pointer 5 one ends fix on pointer cover 3 by hinges fixing, and under groove 4 that pointer puts, collapsible pointer 5 is comprised of two joints, between two joints, can turn folding.Two runners 7,8 are fixed in rotating shaft 10, and two runner diameters are identical, and the length between two runner 7,8 inboards is identical with the length of axle sleeve 9, and axle sleeve 9 is fixed on the below of the pen cap 6.

During use, pin penholder 1, guaranteeing between two runners 7,8 and paper has certain contact force then along two runners, 7,8 rotation directions, to drag penholder, just can draw straight line.When needs picture angle, rotary indicator cover 3 utilizes the groove 4 that pointer puts to find required angle with reticule 2, nib is aimed at and will be drawn on the starting point at angle, collapsible pointer 5 is launched to suitable length, whole device is rotated to the needle point that makes collapsible pointer 5 around nib to be fallen on the one side at the angle of having finished, then the direction along the rotation of two runners 7,8 drags penholder 1, another side that can the picture angle.

Claims (4)

1. the pen that can draw straight line and angle, comprise: a penholder, a pointer cover, a collapsible pointer, a pen cap, an axle sleeve, two runners, a rotating shaft, it is characterized in that: penholder is vertically fixed on the center of the pen cap, and perpendicular to the setting-out plane, reticule is carved with in the middle top of penholder, there is a pointer cover that is enclosed within on penholder and can rotates around penholder reticule below, the groove that pointer puts is engraved in pointer cover top, collapsible pointer one end fixes on pointer by hinges fixing and puts, and be positioned at groove that pointer puts under, two runners are fixed in rotating shaft, axle sleeve is fixed on pen cap below.
