Abstract
The invention discloses a sliding miter square and relates to a drawing tool of student stationery, which brings convenience for students to draw height lines, vertical lines and parallel lines. The sliding miter square comprises two straight poles with sliding grooves and a sliding rails which are matched with each other; the sliding rail on one straight pole is embedded in the sliding groove of the other straight pole and is in matching connection with the sliding groove of the other straight pole, and moreover, the sliding rail can move in the sliding groove. In sliding process, the two straight poles are vertical to each other all the time, and the two straight poles are provided with scale lines and marks for showing length. When in use, one straight pole is fixed relatively, and the other straight pole is moved to a specific position, and thus, height lines, vertical lines and parallel lines can be drawn conveniently. Used for drawing, the sliding miter square is more convenient than a set square and a straight scale.
Description
Technical field
The present invention relates to the drawing instrument in the student stationery, especially a kind of sliding miter square that can help the student to make height easily, make vertical line, draw parallel lines.
Background technology
At present, in students in middle and primary schools, generally use set square to make height on the geometric figure base, make the vertical line of straight line, use the combination of set square and ruler to draw parallel lines, but in actual teaching, the student utilizes two right-angle sides of set square to do high being difficult to and holds, and utilizes the combination of set square and ruler to draw parallel lines and is difficult to operation, and these difficulties have very big relation with defectives of drawing tools.
Summary of the invention
For high to the student to geometric work, make vertical line and draw parallel lines to bring convenience, it is convenient to bring for the drawing designer when drawing, the invention provides sliding miter square.
Technical scheme of the present invention: sliding miter square, two straight-bars that have chute and slide rail, chute and slide rail on these two straight-bars complement one another, slide rail on straight-bar is embedded in the chute of another root straight-bar and is connected, and slide rail can move in chute, in the process of sliding, two straight-bars remain mutually vertically, are carved with graduation mark and the mark of representing length on two straight-bars.When using the present invention that a certain base of figure made height or made vertical line, as long as a straight-bar of sliding miter square is close on the base of figure, move another root straight-bar to assigned address, by just can make height or the vertical line on the figure appointment base easily in the method for its edge picture straight line; When using the present invention to draw parallel lines, the position relative fixed of a straight-bar moves another root straight-bar, whenever moves the line that once draws at its edge, has so just obtained one group of parallel lines.
Beneficial effect: because the present invention is made up of two straight-bars that agree with mutually, these two straight-bars are remaining dynamic vertical relation mutually in agreeing with mobile process, the student is as long as be close to the base to a straight-bar of sliding miter square, move another root straight-bar and just can make height easily to assigned address, Billy with set square do high, to make vertical line much easier, it is more apparent quick to utilize sliding miter square to draw parallel lines.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of outline drawing of the present invention.
In the drawings: 1. trough of belt straight-bar, 2. band rail straight-bar, 3. chute, 4. slide rail
The specific embodiment
In Fig. 1, have slide rail (4) on the band rail straight-bar (2), have chute (3) on the trough of belt straight-bar (1), slide rail (4) is embedded in the chute (3) and is connected, slide rail (4) can move up and down in chute (3), and it is vertical to be with rail straight-bar (2) and trough of belt straight-bar (1) to remain, and band rail straight-bar (2) respectively has a side in same plane with trough of belt straight-bar (1), make that band rail straight-bar (2) all can be close to paper with trough of belt straight-bar (1) when mapping.When drawing parallel lines, sliding miter square is placed on the paper, moves up and down band rail straight-bar (2) and just can be close to the edge of being with rail straight-bar (2) many straight lines that are parallel to each other that draw with pen; Do high, when making vertical line, can put the sliding miter square half-twist of Fig. 1 position, the edge of trough of belt straight-bar (1) overlaps with the base of figure, and move left and right band rail straight-bar (2) just can be close to pen and be with the edge of rail straight-bar (2) to make height easily, make vertical line in place.
Be carved with the graduation mark and the mark of expression length on band rail straight-bar (2) and trough of belt straight-bar (1), the present invention can also be used as common ruler use like this.
If 0 graduation mark of expression length above the band rail straight-bar (2) is overlapped with the edge of trough of belt straight-bar (1), the present invention can also measure the distance that geometric height, metric point arrive straight line easily so.
Claims (3)
1. sliding miter square, it is characterized in that: two straight-bars that have chute and slide rail, chute and slide rail on the straight-bar complement one another, slide rail on straight-bar is embedded in the chute of another root straight-bar and is connected, this mode that is connected is: slide rail can move in chute, and two straight-bars are vertical mutually.
2. sliding miter square according to claim 1 is characterized in that: on two straight-bars graduation mark and the mark of representing length arranged.
3. sliding miter square according to claim 1 is characterized in that: wherein represent that 0 graduation mark of length overlaps with the edge of another root straight-bar on a straight-bar.
