A set square with a tongue piece is composed of a set square body, a tongue piece mounted in the middle of the set square body and a tongue piece shaft. The tongue piece can rotate around the axis of the tongue piece shaft by 90 degrees when being stirred by 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
A kind of set square with tongue piece relates to the stationery technical field, relates in particular to a kind of drawing instrument.
Background technology
Being used at present the set square of drawing, is a class flat tool mostly, is inconvenient to during drawing move, and particularly drawing with pen is easy to when moving ink marks is dragged flower and makes a mess of works.
Summary of the invention
The purpose of this invention is to provide a kind of convenient mobile set square, and be unlikely drawn lines are made a mess of.
This a kind of set square with tongue piece is comprised of set square body, the tongue piece and the tongue piece axle that are installed in the body middle part.Tongue piece links to each other with body by the tongue piece axle, and tongue piece and tongue piece axle are connected.Insert respectively in two coaxial apertures of body at the two ends of tongue piece axle.Stir tongue piece with hand, relative set square body plane, tongue piece is between 0 to 90 ° around the angular range that tongue piece axle axis rotates.
The advantage of a kind of set square with tongue piece of the present invention is: use this set square to draw or during drawing, tongue piece is become 90 ° position by going to the overlapping position of body with body, hand pinches tongue piece can make things convenient for the movable triangular plate, can keep picture clean; Tongue piece can be reversed again when not in use position original and that body is overlapping, instant packed, deposit and carry.
Description of drawings
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.Among the figure: 1 is body, and 2 is tongue piece, and 3 is the 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 comprised of set square body 1, the tongue piece 2 that is installed in body 1 middle part and tongue piece axle 3.Body 1 middle part has that a profile and tongue piece 2 are similar 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 slightly is longer than the hole, the two ends that make things convenient for tongue piece axle 3 under the effect of certain external force, insert respectively body 1 middle part the hole the two side with body 1 parallel plane two coaxial apertures in and do not come off.The degree of depth in hole is a bit larger tham the thickness of tongue piece 2.Should satisfy with the cooperation between the tongue piece axle 3 with tongue piece axle 3 hole walls parallel and that be affixed: under the stirring of finger, relative set square body 1 plane, tongue piece 2 is between 0 to 90 ° around the angular range that tongue piece axle 3 axis rotate; And tongue piece 2 cannot not stop looseningly because tongue piece axle 3 closely cooperates with the hole wall when not stirring.When described 90 ° of states are this set square body 1 lain against drawing paper, lift tongue piece 2 with hand and make tongue piece 2 vertical with set square body 1 plane, as shown in Figure 1.
Use this set square to draw or during drawing, by going to position with 1 one-tenth 90 ° of bodies with the overlapping position of body 1, hand pinches tongue piece 2 can this set square of convenient, flexible movement with tongue piece 2, and can keep drawing or picture clean.Tongue piece 2 can be reversed again when not in use the overlapping position of original and body 1, instant packed, deposit and carry.
