Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model. In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "upper surface", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, an embodiment of the present invention: a simple and portable drawing device for mechanical drawing teaching comprises a bottom plate 1, wherein a sliding chute 2 is arranged on the bottom plate 1, a sliding block 4 is connected in the sliding chute 2 in a sliding mode, and a ruler 7 linked with the sliding block 4 is arranged on the sliding block 4; a first scale value 6 is arranged on the scale 7, and a second scale value 5 which is the same as the first scale value 6 is arranged on one side of the sliding chute 2 facing the scale 7; the parallelism of a plurality of line segments is controlled by moving the scale 7 back and forth; the second scale value 6 on the bottom plate 1 is matched with the first scale value 5 on the scale 7 to control the size between parallel lines.

In conclusion, the parallelism of a plurality of line segments is controlled by moving the scale 7 back and forth, the size precision between the parallel lines can be controlled by matching the second scale value 5 of the bottom plate 1 with the first scale value 6 of the scale 7; based on the technical scheme, the drawing device is simple in structure and convenient to use, not only controls the drawing precision of students in a teaching link, but also improves the drawing efficiency, so that the product is higher in practicability, and the drawing level of the students is better improved.
