Abstract
The utility model provides a multi-purpose ruler which not only can draw a straight line section, but also can draw a circular arc and can realize the function conversion between the ruler and a compass conveniently. The technical proposal of the utility model is as follows: a multi-purpose ruler includes a ruler body with scale; the ruler body is provided with a first movable cross band and a second movable cross band which can move along the longitudinal direction; and a long groove is arranged along the longitudinal direction of the ruler body. A first pencil fixing hole and a second pencil fixing hole are respectively arranged on the two cross bands, the fixing hole corresponds to the long groove so as to lead the pencil point to be capable of moving along the long groove. The utility model has the advantages that two pencils are fixed on the fixing holes, i.e. a circle or a circular arc is drawn by adopting the pencil point on the fixing hole of the first removable cross band as the center of circle and adopting the distance from the pencil point on the fixing hole of the second removable cross band to the center of circle as the radius, thus conveniently realizing the function conversion between the ruler and the compass.
Description
Technical field
The utility model relates to a kind of drawing instrument, specifically is meant a kind of multipurpose ruler that can realize ruler and the conversion of compasses function.
Background technology
Existing ruler can only be drawn straightway, can not draw circular arc, in drawing course, often needs multiple instruments such as ruler and compasses, and drawing instrument can make that too much desktop is in disorder, and use has inconvenience more, determines that with common compasses radius is also cumbersome; In addition, ruler can not length be difficult to guarantee accurately when drawing straightway, inconvenience especially when drawing many isometric line segments.
Summary of the invention
The utility model is at the problem that prior art exists, and a kind of multipurpose ruler that not only can draw straightway but also can draw circular arc is provided, and can realize the function conversion of ruler and compasses easily.
The technical solution adopted in the utility model is:
A kind of multipurpose ruler, comprise the ruler body that has scale, described ruler body is provided with the first removable horizontal stripe and the second removable horizontal stripe that can move along its longitudinal direction, longitudinal direction along described ruler body also has long groove, be respectively equipped with the first pencil fixing hole and the second pencil fixing hole on two removable horizontal stripes, described fixing hole can move the nib that inserts fixing hole along long groove corresponding to described long groove.
Described long groove parallels with the side of ruler body band scale.
The beneficial effects of the utility model are: two pencils are fixed on the pencil fixing hole, be the center of circle promptly with the pencil nib on the first removable horizontal stripe fixing hole, is radius with the pencil nib on the second removable horizontal stripe fixing hole to the distance of home position, draw circles or circular arc are realized the function conversion of ruler and compasses easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Referring to Fig. 1, a kind of multipurpose ruler, comprise the ruler body 1 that has scale, the ruler body is provided with the first removable horizontal stripe 2 and the second removable horizontal stripe 3 that can move along its longitudinal direction, longitudinal direction along the ruler body also has long groove 11, be respectively equipped with the first pencil fixing hole 21 and the second pencil fixing hole 31 on two removable horizontal stripes, the fixing hole position is corresponding with long groove 11 positions, and the nib that inserts fixing hole can be moved along long groove.Referring to Fig. 2, with two pencils 4,5 are fixed on the first pencil fixing hole 21 and the second pencil fixing hole 31, the first removable horizontal stripe 2 is fixed on the zero graduation position, the second removable horizontal stripe 2 is fixed on the scale position that needs, pencil 5 nibs on promptly can the first removable horizontal stripe fixing hole 21 are the center of circle, distance with pencil 5 nibs on the removable horizontal stripe fixing hole 21 of pencil 5 nibs to the first on the second removable horizontal stripe fixing hole 31 is a radius, draw circles or circular arc, also saved common compasses and need strip out pack into the trouble of compasses of one section pencil-lead, used easily.
