Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to shown in Fig. 1-3, a kind of triangular ruler of bow compasses, including set square 1, slide rail 2 and circular groove 6, the set square 1 is most
Long side is provided with set square scale 8, ensures have longer distance to set set square scale 8；The center of set square 1 is provided with the circle
Groove 6, and it is provided with the slide rail 2 around the edge of circular groove 6；The inner chamber of slide rail 2 is provided with chute 14, and chute 14 is a kind of T-shaped
Chute 14；The inner side of circular groove 6 sets litter 4, and the inner side of litter 4 is provided with neck 11；The side of litter 4 is provided with sliding axle
