The multi-functional protractor of one of the present utility model, main body is protractor, and its innovative point is: also comprise driver plate bar, compasses, rubber sassafras, index lever and hinge; Described hinge is fixedly connected on the lower center position of protractor upper surface; Described hinge connects a driver plate bar; The right-angle side of described protractor is fixedly connected with one side pin of compasses; Two limit pin of described compasses are connected with an index lever; The top end of described compasses is also connected with a rubber sassafras.

As preferably, described driver plate bar is flat slender axles.

As preferably, described index lever is rectangular panel blocks.

The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, simple and compact for structure, convention amount hornwork, compasses and rubber sassafras are organically collected and is combined together, achieve one-object-many-purposes, be convenient for carrying, remove the time of the various instrument of taking that student uses simultaneously from, saved learning time and energy, protractor arranges driver plate bar simultaneously and facilitate reading angular, compasses arrange index lever, convenient to compasses subangle.

Accompanying drawing illustrates:

For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.

Fig. 1 is structural representation of the present utility model.

1-protractor; 2-driver plate bar; 3-compasses; 4-rubber sassafras; 5-index lever; 6-hinge.

Embodiment:

As shown in Figure 1, this embodiment by the following technical solutions: main body is protractor 1, also comprises driver plate bar 2, compasses 3, rubber sassafras 4, index lever 5 and hinge 6; Described hinge 6 is fixedly connected on the lower center position of protractor 1 upper surface; Described hinge 6 connects a driver plate bar 2; The right-angle side of described protractor 1 is fixedly connected with one side pin of compasses 3; Two limit pin of described compasses 3 are connected with an index lever 5; The top end of described compasses 2 is also connected with a rubber sassafras 4.

Wherein, described driver plate bar 2 is flat slender axles; Described index lever 5 is rectangular panel blocks.

The using state of this protractor is: during measuring angle, can pass through driver plate bar quick position angle, reach accurate sense data, and rubber sassafras can use in wiping, and the index lever on compasses can when compasses use, and mode angle expands, and plays positioning action.

More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
