Abstract
The utility model relates to compasses with a pen point being the fulcrum. The compasses comprise a first body (2) with the inner side being provided with a first connecting plate (9) and a second body (5) with the inner side being provided with a second connecting plate (7). The first connecting plate (9) is hinged to the second connecting plate (7) through a connecting shaft (8). The lower end of the first body (2) is connected with a first circular elastic sleeve (1) used for mounting a first pencil, and the upper end of the first body (2) is connected with a clamping groove (3) which is a slit. The lower end of the second body (5) is connected with a second circular elastic sleeve (6) used for mounting a second pencil. The upper end of the first body (2) is connected with a clamping plate (4) which can move in the clamping groove (3).
Description
Technical field
The utility model relates to a kind of compasses, specifically a kind ofly can make with nib the compasses of fulcrum.
Background technology
In the two legs of existing compasses, one is used for installing metal needle with needle stand, and another is used for installing pencil-lead with the pen core seat.At first metal needle and pencil-lead are installed during use, and then take the metal needle end points as center of circle fulcrum, the rotation pencil core is drawn circle.Its major defect is: the first, metal needle is more sharp-pointed, not only carries inconvenience, and usually can pierce through whatman while using.The second, metal needle and pencil-lead small volume, be easy to drop, keeping inconvenience., so the compasses of this quasi-tradition are not suitable for being placed in ordinary writing case, usually need special compass case to contain.
The utility model content
Technical problem to be solved in the utility model is, a kind of compasses of making fulcrum with nib are provided, and after two pencils are installed, with the nib of wherein, makes fulcrum, and another branch is drawn circle, to overcome the defect of existing compasses.
In order to solve this technical problem, the utility model by the following technical solutions:
Make the compasses of fulcrum with nib, it is characterized in that: comprise inboard the first noumenon with the first yoke plate, inboard the second body with the second yoke plate, described the first yoke plate and the second yoke plate are mutually hinged by shaft coupling; The lower end of described the first noumenon is connected with for the first round and elastic sleeve that first pencil is installed; The upper end of the first noumenon is connected with buckling groove, and described buckling groove is a slit; The lower end of the second body is connected with for the second round and elastic sleeve that second pencil is installed; The upper end of described the first noumenon is connected with card adapter plate that can be movable in described buckling groove.
Good effect of the present utility model is: two pencils are embedded respectively in the round and elastic sleeve, with the nib of first pen, do center of circle fulcrum, second pen can the picture circle.And the card adapter plate of drawing the second upper end of bowlder is in the buckling groove of the first upper end, twists these compasses picture each position of bowlder stressed more balanced, uses more convenient.
In addition, during due to use, two pencils are installed and are got final product, do not re-use metal needle and the pencil-lead of small volume, can be contained in easily in ordinary writing case, carry, preserve convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
, for the ease of understanding and implementing, below in conjunction with drawings and Examples, further illustrate the utility model.
As shown in Figure 1, the utility model comprises inboard the first noumenon 2 with the first yoke plate 9, and inboard the second body 5, the first yoke plates 9 with the second yoke plate 7 and the second yoke plate 7 are mutually hinged by shaft coupling 8.
The lower end of the first noumenon 2 is connected with the first round and elastic sleeve 1, is used for installing first pencil during use.The upper end of the first noumenon 2 is connected with buckling groove 3, and described buckling groove 3 is a slit.The lower end of the second body 5 is connected with the second round and elastic sleeve 6, is used for installing second pencil during use.The upper end of the first noumenon 2 is connected with can be in the card adapter plate 4 of described buckling groove 3 interior activities.
Nib with a pen is done the center of circle, and another pen can the picture circle.Two yoke plates are relatively rotated around shaft coupling 8, can change two angles between pen, and then draw circle or the circular arc of obstructed diameter.
