Description of symbols: L shape main scale 1, support column 12, bull stick 13, clamping bar 14, connecting hole 15, connects long side mapping portion 11
It connects ruler 19, L shape auxiliary scale 2, tape 3, attachment device 4, main fixed connecting rod 41, main bull stick 42, main clamping ba 43, adjust pars convoluta 44.
Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing.
As shown in Figures 1 to 9, multifunctional drawing ruler attached bag of the invention includes L shape main scale 1, L shape auxiliary scale 2 and attachment device
4, attachment device 4 is connected L shape main scale 1,2 activity of L shape auxiliary scale by connecting the connecting hole 15 of ruler 19 in L shape main scale 1, L shape auxiliary scale 2
It connects, to form multifunctional drawing ruler.
As shown in Figure 1, Figure 2 and shown in Fig. 9, L shape main scale 1 is identical with L shape 2 structures of auxiliary scale in the present invention, and L shape main scale 1 includes length
11, two sets of side mapping portion tape clamping device, connecting hole 15, connection ruler 19, wherein long side mapping portion 11 with connect ruler 19 mutually
Vertically, shape is at L-shaped.Two sets of tape clamping devices are set in long side mapping portion 11, and tape clamping device includes support column 12, bull stick
13, clamping bar 14.Support column 12 is fixedly connected in long side mapping portion 11, and 13 one end of bull stick is movably connected on support column 12, folder
Bar 14 is fixedly connected on the other end of bull stick 13, and clamping bar 14 is perpendicular to long side mapping portion 11.Tape 3 can pass through the spiral shell on clamping bar 14
Mother is fixed on clamping bar 14, and after relaxing nut, tape 3 can be removed from clamping bar 14.It connects and connecting hole 15 is set on ruler 19, even
It is settable multiple or one to connect hole 15, it is adjustable to make round or elliptical size when being arranged multiple, it is arranged 3 in the present invention
Connecting hole 15.
As shown in Figures 1 to 9, attachment device 4 of the invention includes main fixed connecting rod 41, main bull stick 42, main clamping ba 43.
Screw thread is arranged in main fixed connecting rod 41, and main fixed connecting rod 41 passes through the connecting hole 15 of two connection rulers 19, and living by nut
Dynamic connection.In this way when needing to rotate, loose nut is that is, rotatable to make two connection rulers 19 at an angle.Main bull stick 42 1
End is movably connected on main fixed connecting rod 41, and main clamping ba 43 is fixedly connected on the other end of main bull stick 42, and main clamping ba 43 is vertical
In connection ruler 19.Tape 3 can be fixed on main clamping ba 43 by the nut on main clamping ba 43, can be from main folder after relaxing nut
Tape 3 is removed on bar 43.
Tape 3 of the invention can be stainless steel graduated scale (the stainless steel scale of such as application number 201720114896.5
Ruler), tape 3 or the manufacture of elastic silica gel material.After tape 3 is fixed in this way, mutual curve is more obvious, and most
It is good not use connecting rope (connecting rope in such as application number 201510943485.2), because connecting rope is without elasticity, constant formation
Curve.
As shown in fig. 7, L shape main scale 1 and L shape auxiliary scale 2 are formed a U-shaped, then pull four bull sticks drawing bowlder
13, for four points on the same circumference, tape 3, which is fixed on clamping bar 14, can draw circle.As shown in figure 8, when drawing oval,
Rotation makes L shape main scale 1, L shape auxiliary scale 2 that certain angle be presented, and tape 3 is then sequentially fixed at four clamping bars 14 and main folder again
On bar 43.After curve is fixed, draw around curve.
In general, curve is best in vertex position curvature, if the device of the invention is mapped according to above-mentioned technical proposal,
There is also the deficiencies that vertex curve cannot preferably be met the requirements, and in the prior art, and there are no technologies how to solve this problem
Scheme.As another embodiment of the invention, pars convoluta 44 is adjusted in setting on main clamping ba 43, as shown in Figure 10.Adjust pars convoluta 44 can
Think arc steel plate, set gap on rear side of the nut on main clamping ba 43 accordingly, steel disc is compressed by nut, makes steel disc
Downward bending, curvature is bigger, and the curvature on vertex is bigger, to improve the accuracy of mapping.
