The movable rotor of matching, the movable rotor has a mobile through hole for being used to pass through the connecting rope.
Because movement governor itself can produce rotation in moving process, in order to avoid there is connecting rope winding
Situation, should allow that movable rotor rotates, therefore, employ and movement is connected in movable rotor
The structure of bearing, the rotation of movable rotor is offset by the rotation of mobile bearing, it is to avoid connecting rope winds.
It is preferred that the inwall of the mobile bearing has internal thread, the outer wall of the bottom of the movable rotor
With the external screw thread matched with the internal thread.Spiral shell is used by between mobile bearing, movable rotor
Line attachment structure so that can both be interfixed between mobile bearing and movable rotor, it is ellipse in order to draw
Circle；Again can be with the distance between orderly adjustment connecting rope and movement governor, in order to draw hyperbola.
It is preferred that the inwall of the mobile bearing has a pair of symmetrical grooves, the movable rotor
The outer wall of bottom there is projection with the groove match.By mobile bearing, movable rotor it
Between using raised and groove structure so that can both be interfixed between mobile bearing and movable rotor, with
It is easy to draw oval；Again can be with the distance between orderly adjustment connecting rope and movement governor, in order to paint
Hyperbola processed.
It is preferred that the movable rotor is T-shaped.
It is preferred that the drawing pen is pencil.During Graphing of Engineering, drawing pen selection pencil.
It is preferred that the drawing pen is chalk.When classroom instruction is drawn, drawing pen selection chalk.
Positive effect of the invention is：By designing special ellipse-hyperbolic diagraph, solve
The problem of inconvenient graphing when Graphing of Engineering and classroom instruction.

Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but is not therefore limited the present invention to
Among described scope of embodiments.
Embodiment
Understood incorporated by reference to Fig. 1, a kind of ellipse-hyperbolic diagraph 100, it includes：Focus is positioned
Device 1,2, connecting rope 3, can along connecting rope 3 slide movement governor 45.
Understood incorporated by reference to Fig. 1-2, connecting rope 3 is marked with scale, for accurate Drawing different size
Ellipse or hyperbola.The two ends of connecting rope 3 are connected with focus positioner 1,2, a drawing pen 7
The mobile bearing 4 of movement governor 45 is fixed on by adapter sleeve 6.Drawing pen 7 can for chalk or
Pencil, is respectively used to meet classroom instruction or Graphing of Engineering needs.
Understood incorporated by reference to Fig. 1, focus positioner 1 is included for focus positioner to be fixed on into blackboard
Or fixed component 13, rolling bearing 11, rotor 12 on drawing paper, focus positioner 2 is including having
There are fixed component 23, rolling bearing 21, the rotor 22 of identical function.The outer wall of rolling bearing 11 with it is solid
The inwall for determining part 13 is connected, and the inwall of rolling bearing 11 is connected with the outer wall of rotor 12.This
Sample, rotor 12 can just be realized rotating with the center of circle of oneself.The inside of rotor 12,22 is respectively provided with a use
In the clamping part of the rope 3 that is clamped and connected, the tune for the length of connecting rope 3 can be realized by clamping part
It is whole.In order that focus positioner 1,2 is fixed on blackboard, fixed component 13,23 is magnet material.
Understood incorporated by reference to Fig. 1-2, movement governor 45 includes mobile bearing 4 and mobile bearing 4
The T-shaped movable rotor 5 that matches of inwall.T-shaped movable rotor 5 has one for wearing connecting rope 3
The mobile through hole 51 crossed.In order that T-shaped movable rotor 5 can be fixed in mobile bearing 4, can be with
Make the inwall for moving bearing 4 that there is internal thread, and the outer wall of the bottom of T-shaped movable rotor 5 have with it is interior
