It is to be badly in need of in the industry.
Summary of the invention:
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model there are provided a kind of retractable multifunctional
Drawing rule, is integrated with the functions such as ruler, protractor, compasses, chalk sleeve, can draw arbitrarily angled straight line, circular arcs with arbitrary angles
And concentric circular.
To achieve these goals, the technical solution of the utility model is: by ruler I (1), ruler II (2), protractor
(3), ruler III (4), folding (5), ruler IV (6), ruler V (7), ruler VI (8) forms, and wherein bearing pin connects folding hole 1
(501) connecting two foldings, protractor (3) throughput hornwork hole (301) is fixed with bearing pin, and folding hole 2 is passed through in folding (5)
(502) pass through with the ruler I (1) connecting hole (102) in ruler I (1) and the ruler II (2) connecting hole (201) in ruler II (2)
Screw connection manner is connected, slide block slot 1 (101) in ruler I (1) and slide block slot 2 (104) and the slide block 1 in ruler III (4)
(404) it is connected with slide block 2 (406), the ball grooves (103) in ruler I (1) and the top ball grooves (405) in ruler III (4)
It is connected.
The utility model has the advantage of that volume is little, be easy to carry, low cost of manufacture, applied widely, highly versatile.
