Further, on described main scale handle and dial, be provided with graduation mark.
The utility model has the advantages that: the relative rotation of teaching ruler by major and minor chi handle and sliding realize draw straight line, arbitrarily parallel lines, arbitrarily angled line and
with the function of interior circle and circular arc.The angle of accurately locating between major and minor chi handle by dial needle reaches the arbitrarily angled line of drafting; Relative sliding between secondary chi handle and main scale handle reaches the function of drawing any parallel lines.Have in addition a function of T-square.
Brief description of the drawings
Fig. 1 is the assembling schematic diagram of disc type multi-functional mechanical drawing teaching chi of the present utility model.
Fig. 2 is the structural representation of disc type multi-functional mechanical drawing teaching chi of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail, be to be noted that described specific embodiment is only intended to be convenient to understanding of the present utility model, and it is not played to any restriction effect.
Referring now to Fig. 1,2, described disc type multi-functional mechanical drawing teaching chi comprises that chalk adds collar 2, chalk mounting cylinder 3, main scale handle 4, dial 5, tuning drive gear 6, pad 7, individual layer knurled nut 8, the stubborn knurled nut 9 of hand, screw mandrel 10, staking nut 11, secondary chi handle 12, compass foot 13, it is characterized in that, the main body of the length direction of described main scale handle 4 is provided with the chute of strip, and one end of described main scale handle 4 is provided with cylinder boss; One end of described secondary chi handle 12 arranges assembling circular hole, and the other end is provided with cylinder boss; Described screw mandrel 10 is arranged in the chute of described main scale handle 4 and the assembling circular hole of secondary chi handle 12 ends, described screw mandrel 10 is exposed to the part in described main scale handle 4 outsides and assembles successively described dial 5, tuning drive gear 6, pad 7, individual layer knurled nut 8, the stubborn knurled nut 9 of hand, and described screw mandrel 10 is exposed to the part in described secondary chi handle 12 outsides and assembles described staking nut 11; Described compass foot 13 is arranged on the cylinder boss of secondary chi handle 12 other ends, and described chalk mounting cylinder 3 is arranged on the cylinder boss of main scale handle 4 other ends, and described chalk adds on the external cylindrical surface that collar 2 is pressed in chalk mounting cylinder 3.
In the time of assembling disc type multi-functional mechanical drawing teaching chi of the present utility model, first closed main scale handle 4 and secondary chi handle 12, then screw mandrel 10 is inserted in the circular hole in main scale handle 4 and secondary chi handle 12 left sides, above main scale handle 4, dial 5, tuning drive gear 6, pad 7, individual layer knurled nut 8, the stubborn knurled nut 9 of hand are tightened above being assemblied in successively screw mandrel 10, then tightened above staking nut 11 being assemblied in to screw mandrel 10 below secondary chi handle 12.Compass foot 13 is arranged on the cylinder boss of secondary chi handle 12 tops, and chalk mounting cylinder 3 is arranged on the cylinder boss of main scale handle 4 tops, inserts chalk 1, chalk is added on the external cylindrical surface that collar 2 is pressed into chalk mounting cylinder 3, thereby compress chalk 1.
