The front end of the horizontal component of described L frame is provided with line mouth.
The middle part of described crossbeam is provided with wire loop.
The periphery of described line wheel is provided with the wire casing of ring-type.
Poroid string holes is provided with in described wire casing on described line wheel.
Be provided with line stretcher between described two lines wheel, the two ends, left and right of described line stretcher are wrapped in the described wire casing on the line wheel of two, described left and right respectively; Described line stretcher is through described line mouth.
Described line stretcher is provided with the pen cap of ring-type, and the described pen cap can move and also can be fixed on described line stretcher on described line stretcher.
Be provided with described drive line between described two lines wheel, the two ends, left and right of described drive line are wrapped in the described wire casing on the line wheel of two, described left and right; Described drive line is through the described wire loop on described crossbeam.
Described line stretcher and described drive line are overall structure.
The invention has the beneficial effects as follows: various required hyperbola can be drawn easily.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of the embodiment of the present invention.
Fig. 2 is the front elevation of line wheel.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the structure chart of wind spring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention is by L frame 1, line wheel 2, crossbeam 3, wire loop 31, wheel carrier 11, wheel shaft 13, line mouth 12, line stretcher 4, drive line 5, the pen cap 41 and wind spring 6.
L frame 1 is in L shape, and L frame 1 has two; Crossbeam 3 is in strip, and two L framves 1 are arranged on the two ends, left and right of crossbeam 3, and two, left and right L frame 1 is symmetrical on crossbeam 3; L frame 1 can move horizontally on crossbeam 3, and two L framves 1 also can be fixed on crossbeam 3, so just can regulate the distance between two L framves 1; The horizontal component of two the L framves 1 in left and right is all provided with wheel carrier 11, and wheel carrier 11 is provided with aperture, and wheel carrier 11 is provided with wheel shaft 13 through the aperture on wheel carrier 11; Two, left and right line wheel 2 is enclosed within the wheel shaft 13 on two L framves 1 respectively.
The front end of the horizontal component of L frame 1 is provided with line mouth 12, and line mouth 12 is provided with little hole horizontal and runs through line mouth 12.
The middle part of crossbeam 3 is provided with wire loop 31, and wire loop 31 is fixed on the middle part of crossbeam, is provided with little hole horizontal and runs through wherein in wire loop 31.
As shown in Figures 2 and 3, the periphery of line wheel 2 is provided with the wire casing of ring-type; Poroid string holes 23 is provided with in the wire casing of line wheel 2; Be provided with line stretcher 4 between the line wheel 2 of two, left and right, the two ends of line stretcher 4 are wound around in the wire casing 21 on online wheel 2 respectively; Line stretcher 4 is through line mouth 12; By being counterclockwise wound around on the line wheel 2 of line stretcher 4 on crossbeam 3 left side, the line wheel 2 of line stretcher 4 on the right of crossbeam 3 presses wrapped anti-clockwise.
Line stretcher 4 is provided with the pen cap 41 of ring-type, and the pen cap 41 can move and also can be fixed on line stretcher 4 on line stretcher 4.
Be provided with drive line 5 between two line wheels 2, the two ends of drive line 5 are wound around in the wire casing on online wheel 2 by string holes 23; Drive line 5 is through the wire loop 31 on crossbeam 3; The line wheel 2 of drive line 5 on crossbeam 3 left side presses wound clockwise, the line wheel 2 of drive line 5 on the right of crossbeam 3 presses wrapped anti-clockwise.
Wheel shaft 13 on the right of crossbeam 3 and the line on the right of crossbeam 3 are provided with wind spring 6 between taking turns 2, and wind spring 6 takes turns 2 one clockwise reply pulling force to the line on the right of corresponding crossbeam 3.
In the present invention, line stretcher 4 and drive line 5 also can be integrally-built guy structure.
The present invention uses like this: when not in use, because the factor of the reply pulling force of wind spring makes line stretcher and drive line all be in the state tightened; During use, being placed on by two line mouths needs in the hyp bifocal of picture, also fix the pen cap according to the hyp parameter adjustment pen cap to corresponding position and then pen is inserted in the pen cap line stretcher that stretches, in the process of drawing, remain that the line stretcher on pen cap both sides is all in exceptionally straight state, stretching limit, such limit stroke goes out the track of nib, and the track drawn is exactly the hyperbola of standard.
