Embodiment：
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection：
A kind of Portable type compasses as shown in Figure 1, including compasses rotary head 1, the first compasses pole 2, the second compasses pole 3 with
And bindiny mechanism, the bindiny mechanism include fixing shell 4, gear mechanism and spaced scale disk 5, the fixing shell 4 consolidate
Surely it is connected between the compasses pole 2 of compasses rotary head 1 and second and the second compasses pole 3, the gear mechanism is placed in fixation
In shell 4 and including intermeshing first gear disk 6 and second gear disk 7, and dismantle and install for convenience, described first
The rotating shaft of toothed disc 6 and second gear disk 7 is movably connected in fixing shell 4.
The first gear disk 6 and second gear disk 7 are respectively fixedly connected with the first compasses pole 2 and the second compasses
The end of the non-pin pin of pole 3, the spaced scale disk 5 is placed in the rear portion of first gear disk 6 and at its disk body edge provided with advance
The numerical value of demarcation, the spaced scale disk 5 is coaxially disposed with first gear disk 6, when first gear disk 6 is rotated, spaced scale disk 5
On numerical value it is corresponding with the spacing of the pin pin between the first compasses pole 2, the second compasses pole 3, in the fixing shell 4
It is provided with finger of the fixing shell 4 provided with demarcation directly over the peep hole 8 corresponding with numerical value on spaced scale disk 5, peep hole 8
Show graduation mark 9.
Thus in actual applications, during actual drawing, pass through and open or draw in the first compasses pole and the second compasses branch
Bar relatively moves both, and the spacing in the stitch portion of both ends then changes, and during this both ends the
One toothed disc and second gear disk can be relatively rotated due to intermeshing, thus two toothed discs, and when first gear disk with
And during the relative rotation of second gear disk, the spaced scale disk meeting synchronous axial system after first gear disk, due to being carved in spacing
