Abstract
The utility model relates to a multifunctional caliper, which comprises a caliper and a ruler. The utility model is characterized in that a rotating screw rod (2) connects the main rod (3) with the pencil to be a caliper, a handle (1) is arranged at the upper end of the main rod (3), a locating needle (9) is arranged at the lower end, a ferrule clamp (6) which can be slid is arranged on a pencil (4), a movable cursor clamp (7) is arranged on the ruler (5), the caliper has a multi function, and can be used as the ruler and a square ruler, also can be used as a caliper, the semi-diameter size of a circle can be measured when drawing the circle.
Description
Technical field
The utility model relates to stationery, relates to a kind of Napier's compasses particularly.
Background technology
General compasses can only be drawn circle, and drawn radius of a circle can not be measured simultaneously, and this compasses function of use is single.
Summary of the invention
The purpose of this utility model is to provide a kind of Napier's compasses, and this compasses just can be measured radius of a circle at the picture bowlder, and these compasses can be made ruler and use, and can draw the right angle easily.
The technical solution of the utility model is: suitable position is provided with a ruler in motionless pole lower end, the location of compasses, and this ruler can be measured radius of a circle simultaneously at the picture bowlder, and this compasses can make ruler and square uses.
Above-mentioned Napier's compasses are the lower end suitable positions the motionless pole in the location of compasses, with a termination of rotating screw bolt connection ruler, on ruler, establish sliding pointer, on another pole of compasses, establish the slip locator card, these compasses can be measured drawn radius of a circle simultaneously at the picture circle, and can make other purposes.
Napier's compasses are rationally novel in design, but one-object-many-purposes.
Description of drawings
Figure of description is the structural representation of Napier's compasses.
Among the figure: the 1-handle, 2-rotary screw rod handle, the 3-mobile jib, the 4-paintbrush, the 5-ruler, 6-binds round card, 7-pointer card, 8-rotary screw rod handle, 9-pilot pin.
The specific embodiment
Embodiment 1: shown in Figure of description, Napier's compasses are made up of compasses and ruler compasses, an end that connects ruler (5) at compasses mobile jib (3) lower end suitable position with rotary screw rod (8), mobile jib (3) is connected with paintbrush (4) with rotary screw rod handle (2), slidably pointer card (7) is arranged on the ruler (5), hoop card (6) is arranged on the paintbrush (4), and there is pilot pin (9) on mobile jib (3) top, all is carved with length on mobile jib (2) and the ruler (5).
Embodiment 2: shown in specification, when mobile jib (2) and ruler (5) vertical fixing, can make square usefulness, ruler (5) can be drawn straight line, draws bowlder fixedly mobile jib (2) and paintbrush (4), fixed bit pin (9) location, moving hand card (7) indicates drawn radius of a circle length, and the hoop card (6) that slides is stuck on the ruler (5), hold handle (1), can finish the operation of picture circle.
Claims (2)
