Abstract
A set square provided with a tongue piece comprises a set square body, the tongue piece and a tongue piece shaft, wherein a pit whose appearance is similar to that of the tongue piece is arranged in the middle of the body and is slightly larger than the tongue piece, and the depth of the pit is slightly larger than the thickness of the tongue piece; the tongue piece shaft and the tongue piece are fixedly connected to the root of the tongue piece, the tongue piece is connected into the pit in the body through the tongue piece shaft; the length of the tongue piece shaft is slightly larger than the width of the pit, two ends of the tongue piece shaft are inserted into two coaxial holes in two side walls of the pit in the middle of the body respectively, and the tongue piece shaft cannot fall off; and the tongue piece can rotate around the axis of the tongue piece shaft by 90 degrees under shifting of a finger. The set square is used as a drawing tool, is convenient to use and belongs to the field of stationery.
Description
Technical field
With a set square for tongue piece, relate to stationery technical field, relate in particular to a kind of drawing instrument.
Background technology
Set square for drawing, is a class flat tool mostly at present, is inconvenient to move when drawing, while particularly movement with pen drawing, is easy to ink marks drag flower and make a mess of works.
Summary of the invention
The object of this invention is to provide a kind of convenient mobile set square, and be unlikely drawn lines are made a mess of.
This kind of set square with tongue piece is made up of body, tongue piece and tongue piece axle.There is a profile at body middle part, and size is a bit larger tham the hole of tongue piece to tongue piece is similar, and the degree of depth in hole is a bit larger tham the thickness of tongue piece; Tongue piece axle and tongue piece are fixed on tongue piece root, and tongue piece is connected in this hole by tongue piece axle and body; It is wide that the length of tongue piece axle is slightly longer than hole, and the two ends of tongue piece axle are inserted respectively in two coaxial apertures of two side in the hole at body middle part and do not come off.The angular range that tongue piece rotates around tongue piece axle axis is between 0 to 90 °.
The advantage of a kind of set square with tongue piece of the present invention is: use this set square to draw or when drawing, by tongue piece, by going to the position in 90 ° with body with the overlapping position of body, hand pinches tongue piece can facilitate movable triangular plate, can keep picture clean; Tongue piece can be reversed again when not in use to position original and that body is overlapping, instant packed, deposit and carry.
Accompanying drawing explanation
Fig. 1 is the front elevational schematic of a kind of set square with tongue piece of the present invention angular range that tongue piece rotates when horizontally disposed; Fig. 2 is the schematic top plan view of a kind of set square with tongue piece of the present invention.In figure: 1 is body, 2 is tongue piece, and 3 is tongue piece axle.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is illustrated.
With reference to accompanying drawing 1 and Fig. 2, a kind of set square with tongue piece is made up of set square body 1, the tongue piece 2 that is arranged on body 1 middle part and tongue piece axle 3.Body 1 middle part has one profile is similar to tongue piece 2 and size is a bit larger tham the hole of tongue piece 2, and tongue piece axle 3 is fixed on tongue piece 2 roots with tongue piece 2, and tongue piece 2 is connected in this hole by tongue piece axle 3 and body 1.It is wide that the length of tongue piece axle 3 is slightly longer than hole, and the two ends that facilitate tongue piece axle 3 are inserted respectively in two coaxial apertures of two side in the hole at body 1 middle part and do not come off under the effect of certain external force.The degree of depth in hole is a bit larger tham the thickness of tongue piece 2.And tongue piece axle 3 hole wall parallel and that be affixed should meet with the cooperation between tongue piece axle 3: under the stirring of finger, and set square body 1 plane relatively, the angular range that tongue piece 2 rotates around tongue piece axle 3 axis is between 0 to 90 °; And while not stirring, tongue piece 2 cannot not stop looseningly compared with closely cooperating because of tongue piece axle 3 and hole wall.90 ° of described states are when this set square body 1 is lain against to drawing paper, lift tongue piece 2 and make tongue piece 2 vertical with set square body 1 plane, as shown in Figure 1 with hand.
Use this set square to draw or when drawing, by tongue piece 2, by going to the position in 90 ° with body 1 with the overlapping position of body 1, hand pinches tongue piece 2 can this set square of convenient, flexible movement, and can keep drawing or picture clean.Tongue piece 2 can be reversed again when not in use to position original and that body 1 is overlapping, instant packed, deposit and carry.
