Abstract
The invention discloses a fixed shaft compass. The fixed shaft compass comprises a fixed vertical shaft, a rotary sleeve which can sleeve the fixed vertical shaft in a rotatable mode, a sleeve rail which is fixedly connected to the lateral portion of the rotary sleeve, a cross rod which sleeves the sleeve rail and can horizontally slide and a pen clamping sleeve which can be longitudinally connected to the tail end of the cross rod in an elastic mode. According to the fixed shaft compass, the fixed vertical shaft is arranged to avoid a needle point at the lower end of the vertical shaft from puncturing paper during a rotation process and the fixed vertical shaft plays a role in protecting the paper; the rotary sleeve is connected with the sleeve rail and the cross rod, the cross rod can horizontally move to select the drawing radius of a circle or an arc shape, the circle or a camber line can be drew on the paper by rotating the rotary sleeve, a pen for drawing the circle or the camber line is connected to the tail end of the cross rod through the pen clamping sleeve and has elasticity in the longitudinal direction, namely the pen can slightly move in the longitudinal direction, the compass has an elastic downward pressing force to the pen during the process of drawing the circle or the arc, the pen has tiny extension, a pen tip is tightly adhered to the paper, and accordingly a uniform and clear line can be drew and the paper is not punctured and scraped.
Description
Technical field
The present invention relates to a kind of stationery, particularly relate to a kind of dead axle compasses.
Background technology
The most conventional compasses are that two pin diverge to, and pin is provided with needle point as pivot that is be the home position of picture circle or arc, another pin lead gripper pen core, rotate compasses and the pin cast-over of its lead gripper pen core point place pin are rotated can draw circular arc or circle.But after a circle centre position draws multiple circle or circular arc, also rotate repeatedly for some needle point puncture, rotary course pricks out obvious cavity to this place paper, cavity becomes large, the center of circle of follow-up drawn circle is with regard to inaccuracy, paper has also damaged, and follow-up use procedure also easily causes breakage.
Because current compasses are all the rigidity keeping radius two ends, the compasses foot of drawing nose circle is fixedly connected with compasses and does not cushion, paintbrush needs to press down to make it be adjacent to paper, paintbrush end is firmly excessive, easily causes nib to disconnect or scratch paper, the obstacle that nib place runs into cockling also can make the needle point tripping home position of circle centre position, causes compasses to have some setbacks in picture circle process.Liang Ge compasses foot is firmly uneven and firmly excessive brush tip is firmly too small at circle centre position, then picture circle can be caused unintelligible.Actual circle process of drawing is difficult to remain evenly exert oneself in nib place, causes lines uneven unintelligible.
