Abstract
The utility model relates to compasses, wherein, the inner side of a movable compasses foot is connected with a circular arc arm which takes a screw bolt as a center of a circle. The circular arc arm is marked with scales. The external side of the movable compasses foot is connected with a cylinder as an outer sleeve of a propelling pencil. A cartridge of the propelling pencil is arranged in the outer sleeve of a propelling pencil. The utility model leaves out the trouble of cutting pencils. Meanwhile, the utility model can measure a radius of a circle conveniently by using a scale.
Description
The utility model is a kind of compasses, belongs to culture and education apparatus field.
The compasses kind of producing now and using is a lot, and existing structure complexity, accuracy are high, also have simple in structure, easy to use.Wherein a kind of Student's compasses is to be connected with a rule on moving gauge foot, and moving gauge foot is installed pencil and used.This compasses are simple in structure, utilize rule can measure radius of circle fast, but it are the same with other compasses, also exists the trouble that need sharpen a pencil.
The purpose of this utility model be to provide a kind of save sharpen a pencil trouble and can with the compasses of the mutual usefulness of propelling pencil pen core.
The utility model is achieved in that moving gauge foot, set pattern pin, the handle of compasses link together by bolt, and set pattern underfooting portion is fixed with the rule pin, and set pattern pin and moving gauge foot arc arm intersection have a gap, and its tip is used as the tuning drive gear indicating graduation.It is the arc arms in the center of circle with the bolt that the moving gauge foot inboard is connected with one, and the arc arm is marked with scale, and the moving gauge foot outside is connected with a cylinder as the propelling pencil outer tube, in the propelling pencil pen core is housed.Have a groove in moving gauge foot cylinder inboard, two points can close fully and disturb when two rule pin were merged.
The utility model is compared with background technology, has the following advantages:
1, replaces pencil with propelling pencil, saved the trouble that sharpens a pencil.
2, the cylinder inboard has groove, and two rule pin are completely integrated, and indicates zero point, and scale is measured accurately.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The moving gauge foot of compasses (1), set pattern pin (5), handle (3) link together by bolt (4), it is the arc arms in the center of circle with bolt (4) that moving gauge foot (1) inboard is connected with one; the zero-based scale of arc arm subscript; moving gauge foot (1) outside is connected with a cylinder as the propelling pencil outer tube, in propelling pencil pen core (2) is housed.Have a groove in moving gauge foot (1) cylinder inboard, two points can close up fully when two rule pin were merged.Set pattern pin (5) bottom is fixed with advises pin (6), and set pattern pin (5) has a gap under intersecting with moving gauge foot (1) arc arm, and its tip is as tuning drive gear indicating graduation usefulness, and when two rule pin closed up, zero graduation was indicated in the tip.
Claims (2)
1, a kind of compasses, moving gauge foot, set pattern pin, handle link together by bolt, it is the arc arms in the center of circle with the bolt that the moving gauge foot inboard is connected with one; the arc arm is marked with scale; set pattern pin and moving gauge foot arc arm intersection have a gap; its tip is characterized in that as tuning drive gear: be connected with a cylinder as the propelling pencil outer tube outside the moving gauge foot, in the propelling pencil pen core is housed.
2, compasses according to claim 1 is characterized in that: moving gauge foot cylinder inboard has a groove.
