Abstract
The invention discloses a protractor, consisting of a plurality of sector-shaped blocks. The protractor is characterized in that the sector-shaped blocks are connected through T-shaped clamping grooves and T-shaped clamping blocks. The protractor can be assembled and disassembled, reduces the placement area and provides convenience to carrying around.
Description
Technical field
The present invention relates to a kind of protractor, especially can the protractor of assembly and disassembly.
Background technology
At present, the stationery that known protractor area ratio is general is all large, places and carry all inconvenient.
Summary of the invention
The general stationery of existing protractor area ratio is all large, places and carry all inconvenient, the invention provides a kind of structure simple, can the protractor of easy assembly and disassembly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of protractor, be made up of polylith secter pat 1, it is characterized in that being connected by T-shaped draw-in groove 2, T-shaped fixture block 3 between secter pat 1, secter pat 1 is provided with T-shaped draw-in groove 2, T-shaped fixture block 3 and scale 4, and the scale 4 sign value between each secter pat 1 increases progressively continuously.
The invention has the beneficial effects as follows: protractor can assembly and disassembly, reduce placing area, make to carry convenient.
Accompanying drawing explanation
Fig. 1 is a kind of angle gage structure schematic diagram;
In figure: secter pat 1, T-shaped draw-in groove 2, T-shaped fixture block 3, scale 4.
Embodiment
For making the object of the invention, technical scheme clearly understands, below in conjunction with accompanying drawing specific embodiment, the invention will be further described.
See accompanying drawing 1, a kind of protractor, is made up of polylith secter pat 1, it is characterized in that being connected by T-shaped draw-in groove 2, T-shaped fixture block 3 between secter pat 1, secter pat 1 is provided with T-shaped draw-in groove 2, T-shaped fixture block 3 and scale 4, and the scale 4 sign value between each secter pat 1 increases progressively continuously.
During use amount hornwork, four secter pats 1 are connected in turn by T-shaped draw-in groove 2, T-shaped fixture block 3 can normal use amount hornwork, finishes using, four secter pats 1 are disassembled respectively, protractor can assembly and disassembly, reduce placing area, make to carry convenient.
