Abstract
The invention discloses an adjustable bow compass pen which comprises a penholder. A groove is formed along the length direction of the penholder. A long needle is arranged in the groove. The adjustable bow compass pen further comprises a sliding seat, a clamping seat and a universal ball head. Clamp grooves are formed at two ends along the width direction of the groove. The sliding seat is laid in the clamp grooves and is capable of sliding along the clamping grooves. The long needle is connected with the sliding seat through the universal ball head. A clamping seat is arranged inside one end of the groove along the length direction. According to the adjustable bow compass pen, a pen and a bow compass are combined as a whole so that occupied space of the pen and the bow compass is reduced. The long needle serving as the bow compass is capable of vertically sliding along the length direction of the pen so that the diameter of a to-be-drawn circle is changed and the diameter of the to-be-drawn circle is not limited. When a bow compass function is not used, the long needle is taken back to the groove and one end of the long needle is clamped by the clamping seat so that the long needle does not move out from the groove, and therefore the technical problem that a traditional bow compass can stab a person or scratch articles easily is solved and the adjustable bow compass pen is safe and convenient to carry.
Description
Technical field
The present invention relates to a kind of pen, relate in particular to a kind of adjustable compass pen that compasses are used that can be used as, belong to the stationery technical field.
Background technology
In daily learning life, pen and compasses are one of requisite instruments in study article, the pen that uses at present and compasses are separately independently mostly, separately use, function is relatively single, need to be simultaneously with two objects that separate alone when going out to carry, take up room, and the as easy as rolling off a log thorn of the contact pin on compasses is to people or scratch article; The compasses that use at present in addition, structure is for being fixedly connected with, and the size of drawing circle has been subject to certain restriction, when needs picture radius of a circle exceeds compasses picture radius of circle, needs to change the compasses of larger specification, very trouble.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of adjustable compass pen that pen and compasses are combined as a whole.
Technical solution of the present invention is achieved in that a kind of adjustable compass pen, comprise penholder, the length direction of described penholder is provided with groove, is provided with minute hand in described groove, it is characterized in that: also comprise slide, grip slipper, universal ball end, the two ends of described recess width direction are provided with draw-in groove; Described slide is embedded in draw-in groove, can slide along draw-in groove; Described minute hand is connected on slide by universal ball end; Be provided with grip slipper in one end of described groove length direction.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of adjustable compass pen of the present invention, pen and compasses are combined as a whole, have not only dwindled both taking up room, and can slide up and down along the length direction of pen as the minute hand that compasses are used, to change picture circular diameter size, make the picture circular diameter unrestricted, in the time need not using calipers function, minute hand can be regained in groove, grip slipper is clamped minute hand one end, it can not shifted out from groove, solved traditional compasses and easily stung people or the technical problem of scratch article, safety easy to carry.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the mounting structure figure that does not use calipers function of a kind of adjustable compass pen of the present invention;
Accompanying drawing 2 is the structural representation of the picture circular diameter of a kind of adjustable compass pen of the present invention when the longest;
Accompanying drawing 3 is the picture circular diameter structural representation the most in short-term of a kind of adjustable compass pen of the present invention;
Wherein: 1, penholder; 2, groove; 3, slide; 4, grip slipper; 5, minute hand; 6, universal ball end; 7, draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1,2,3 is a kind of adjustable compass pen of the present invention, comprise penholder 1, the length direction of described penholder 1 is provided with groove 2, is provided with minute hand 5 in described groove 2, also comprise slide 3, grip slipper 4, universal ball end 6, the two ends of described groove 2 widths are provided with draw-in groove 7; Described slide 3 is embedded in draw-in groove 7, can slide along draw-in groove 7, to regulate the picture circular diameter; Described minute hand 5 is connected on slide 3 by universal ball end 6; Be provided with grip slipper 4 in one end of described groove 2 length directions, when calipers function does not use, minute hand be fixed in groove.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of adjustable compass pen of the present invention, pen and compasses are combined as a whole, have not only dwindled both taking up room, and can slide up and down along the length direction of pen as the minute hand that compasses are used, to change picture circular diameter size, make the picture circular diameter unrestricted, in the time need not using calipers function, minute hand can be regained in groove, grip slipper is clamped minute hand one end, it can not shifted out from groove, solved traditional compasses and easily stung people or the technical problem of scratch article, safety easy to carry.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
