Abstract
The utility model relates to the field of stationery, particular to a ruler with a function of compasses. The ruler comprises a ruler body and is characterized in that a through hole groove is formed in the center of the ruler body, a positioning shaft is arranged below a '0' scale of the front face of the ruler body, the center of the positioning shaft is provided with a cylindrical hole penetrating the positioning shaft and the ruler body, the upper end of the positioning shaft is provided with a nut, and a positioning needle is arranged in the nut; the through hole groove is provided with a slider inside, and the center of the slider is provided with a round hole allowing a pencil to insert. The ruler is simple in structure and convenient to use, functions of the ruler and the compasses are combined integrally, a straight line can be drew while a circle with the determined radius can be drew conveniently, and the ruler is convenient to carry, space saving and is adaptive to widely promotion and application.
Description
(1) technical field
The utility model relates to stationery field, particularly a kind of ruler with calipers function.
(2) background technology
At present; student is at graphing; usually can use ruler and compasses; wherein utilize ruler to draw straight line; utilize compasses to draw circle or circular arc, both function differences, also need to be combined with sometimes; the bowlder of for example drawing predetermined radius length need to measure out the distance between compasses bipod with a yardstick, carry with use all very inconvenient.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of ruler with calipers function, and ruler functions and calipers function are become one, simple in structure, easy to use, be easy to carry.
The utility model is achieved by the following technical solution:
A ruler with calipers function, comprises body, it is characterized in that: scale is carved with on a long limit of body, and the centre of body is provided with the through hole groove that a cross section is " ten " font, and through hole groove is parallel with the scale face of body; The below of body front " 0 " graduation mark is provided with columniform locating shaft, locating shaft center is provided with the cylindrical pin hole that connects locating shaft and body, the center of circle of pin hole overlaps with the intersection point of " 0 " graduation mark and through hole groove axis, locating shaft outer surface is provided with external screw thread, locating shaft upper end is provided with nut, in nut, be provided with and the pin hole pilot pin that cooperatively interacts, pilot pin moves up and down with cap rotation; Columniform slide block is installed in through hole groove, and slide block is provided with the fixture block cooperatively interacting with through hole groove, and slide block center is provided with a circular hole that can insert pencil, and the outer surface of slide block is provided with external screw thread and holding screw is installed, and upper end of slide block is provided with tuning drive gear.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, and ruler functions and calipers function are become one, and can draw straight line, can easily draw again the circle of specifying radius size, and be easy to carry, save space, be suitable for wide popularization and application.
