Abstract
The utility model provides compasses. The compasses comprise a positioning support leg, wherein a straight ruler is arranged on the positioning support leg, is connected with the positioning support leg through a shaft, and can rotate around the shaft; a locking groove is formed at the joint of the positioning support leg and the straight ruler; when the straight ruler is vertical to the positioning support leg, the zero scale of the straight ruler is positioned over a positioning pin; a drawing rod which can be adjusted in a sliding mode is arranged on the straight ruler and is sleeved on the straight ruler through a sliding sleeve; and an adjusting bolt is arranged on the sliding sleeve. The compasses have a simple structure and are convenient to use and high in cost performance; and the straight ruler and the compasses are integrated, so that the required circle can be conveniently drawn, the compasses are convenient to carry and use, and the space is saved.
Description
Technical field
the utility model relates to a kind of stationery, especially a kind of compasses with measurement function.
Background technology
Compasses are to be used for the instrument of draw circles or string in mathematics and drawing, are usually used in construction with ruler and compasses; Existing compasses are drawn bowlder; Must important affair measure out the distance between the compasses bipod with a yardstick,, be fixed on a place to an end that has pin as radius; As the center of circle, rotate a circle an end that has pencil.Cumbersome like this.
The utility model content
The utility model technical problem to be solved is the defective to prior art, and a kind of compasses that have measurement mechanism are provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of compasses comprise the location supporting leg, and said location supporting leg is provided with ruler; Ruler is connected with the location leg shaft; Ruler can rotate around the axis, and said location supporting leg and ruler junction are provided with latch recess, when ruler is vertical each other with the location supporting leg; Ruler " 0 " scale place is positioned at directly over the pilot pin, and ruler is provided with the drawing bar of slidably regulating.
Said drawing bar is enclosed within on the ruler through sliding sleeve, and sliding sleeve is provided with the adjusting bolt.
The utility model adopts above technical scheme to have following technique effect:
The utility model is simple in structure, easy to use, and cost performance is higher; The two unites two into one with ruler and compasses, the required circle that can easily draw, and be easy to carry, easy to use, save the space.
Description of drawings
Fig. 1 is the structural representation of the utility model compasses.
Among the figure: 1. locate supporting leg; 2. ruler; 3. sliding sleeve; 4. drawing bar; 5. adjusting bolt.
The specific embodiment
Below
, explain further details in conjunction with the technical scheme of accompanying drawing to the utility model.
Be a kind of compasses of the utility model among the figure, comprise the location supporting leg, said location supporting leg is provided with ruler; Ruler is connected with the location leg shaft; Ruler can rotate around the axis, and said location supporting leg and ruler junction are provided with latch recess, when ruler is vertical each other with the location supporting leg; Ruler " 0 " scale place is positioned at directly over the pilot pin, and ruler is provided with the drawing bar of slidably regulating.The drawing bar is enclosed within on the ruler through sliding sleeve, and sliding sleeve is provided with the adjusting bolt.
As long as make the accurate picture radius of a circle size required circle that just can easily draw that needs of the drawing pole pair of compasses during use, can ruler be turned to the position parallel with locating supporting leg when not in use.The utility model is easy to carry, and is easy to use, saves the space.
