Abstract
The present invention relates to a kind of compasses because the first bullet contracting unit can automatic spring sharp with retraction compasses, therefore, finger avoids the danger hindered by compasses Jianzha County；Because the first rule that the first compass leg body is arranged, the second rule that the second compasses body is arranged can make up a long ruler with the 3rd rule of setting on shell, therefore has the function of ruler；Because the first compass leg body and the second compass leg body are hinged by gear, pointer it is provided with on gear, angle scale it is provided with on shell, therefore when the first compass leg body and the second compass leg body launch, pinion rotation thus drive the beat of pointer, by angle scale it can be seen that the angle of indicators turn thus obtain the angle that two compass legs launch；Being additionally, since on compasses head and be provided with removable rubber tip such that it is able to pencil writing is carried out wiping, compared with the drawing tool of multiple function singlenesses, the compasses folding and unfolding of the present invention is more convenient.
Description
Technical field
The invention belongs to field of stationery, be specifically related to a kind of compasses.
Background technology
Existing compasses are used to picture circle and the instrument of circular arc.But, existing compasses point is to enter
Row shrinks hiding, therefore, keeps well the most in time and be easy to prick after user makes to be finished compasses
Hinder finger.Further, in existing stationery, compasses, ruler, rubber are three different products,
Although product is single convenient on using, but pretty troublesome when folding and unfolding, and sometimes leaves behind straight
When chi or rubber, mapping can be very inconvenient.It addition, the angle that compass leg is launched by major part compasses
Degree can not well limit.
Summary of the invention
The present invention is carried out to solve above-mentioned problem, it is therefore intended that provide one to have
Angle that effect avoids stabbing, show compass leg launches and use and the convenient compasses of folding and unfolding.
The invention provides a kind of can being prevented effectively to stab, show that angle that compass leg launches is also
And use and the convenient compasses of folding and unfolding, it is characterised in that including: the first compass leg, comprise:

Rule point 112 and pen core 122 stretch out respectively from compasses point cap 111b and pen core cap 121b.
After drafting circle or circular arc complete, by the first compass leg 110 and the second compass leg 120
Merge, and the first switch 113e and second switch 123e is upwards pulled, compasses point 112
With in pen core 122 retraction compasses point cap 111b respectively and pen core cap 121b.
The effect of embodiment and effect
According to the compasses involved by the present embodiment because the first bullet contracting unit can automatic spring with
Retraction compasses point, therefore, finger avoids the danger hindered by compasses Jianzha County；Because the first compasses
The first rule that lower limb body is arranged, on the second rule of the second compasses body setting and shell
The 3rd rule arranged can make up a long ruler, therefore has the function of ruler；Because
First compass leg body and the second compass leg body are hinged by gear, and gear is provided with finger
Pin, shell is provided with angle scale, therefore when the first compass leg body and the second compass leg body
During expansion, pinion rotation thus drive the beat of pointer, by angle scale it can be seen that indicators turn
Angle thus obtain the angle that two compass legs launch；It is additionally, since on compasses head and is provided with
Removable rubber tip such that it is able to pencil writing is carried out wiping, due to compasses of the present invention not
Only there are compasses and draw circle or the function of circular arc, and there is the function of ruler and rubber, with multiple
The drawing tool of function singleness is compared, and folding and unfolding is more convenient.
In the present embodiment, the first compass leg also comprises cutter groove, matches for placement and cutter groove
Pocket knife so that folding and unfolding is convenient.
In the present embodiment, the second compasses also comprise places standby lead water pen core and the instrument of compasses point
Set, more convenient to use.
In the present embodiment, the compasses point side of the first compass leg body can be dismantled, the second compass leg
The lead for retractable pencil side of body can be dismantled, and is convenient for changing lead for retractable pencil and compasses point.
In the present embodiment, shaft also comprises timer, makes compasses of the present invention use function more
Variation.
Above-mentioned embodiment is the preferred case of the present invention, is not intended to limit the protection of the present invention
Scope.
