The bottom of the roller shaft is provided with sucker.
Further, two roller mounts are provided with support, and the upper end of the support offers the slotted eye of left and right insertion; Crossbeam is provided between support in two roller mounts, the two ends of the crossbeam are arranged in the slotted eye, the crossbeam energy Horizontally slip in the slotted eye;The upper end of the support is provided with fixture, and the crossbeam can be fixed on institute by the fixture In stating slotted eye.
The crossbeam middle part is provided with penetration pipe, and the centre of the penetration pipe is provided with the passage of left and right insertion, the passage Side communicates with the external world;The mid portion of the bracing wire passes through passage.
The invention has the beneficial effects as follows:Various required hyperbolies can easily be drawn.

Specific embodiment
With reference to the accompanying drawings and examples the invention will be further described:
Embodiment one
As shown in Figures 1 to 6, its structure of the present embodiment includes roller 1, roller mount 2, line mouth 3 and bracing wire 4;Roller 1 is provided with two Individual, each roller 1 has roller mount 2, and roller mount 2 is in block structure, and roller mount 2 is provided with turning rolls 21, and roller 1 passes through axle Hold and be arranged on turning rolls 21 with roller mount 11;The energy counter roller of roller 1 seat 11 rotates.Roller 1 is provided with the end of a thread hole 50, the end of a thread The effect in hole 50 is that the two ends of bracing wire 4 are fixed on roller 1;Roller mount 2 is provided with line mouth 3, and left and right insertion is provided with line mouth 3 String holes;Two rollers 1 are positioned opposite in left and right, and two roller mounts 2 are positioned opposite in left and right;Drawing is provided between two rollers 1 Line 4;The two ends of bracing wire 4 are fixed and are wrapped on one of roller 1, and the mid portion of bracing wire 4 is wound on another roller 1; The mid portion of bracing wire 4 passes through line mouth 3;Wind spring is provided with inside the roller 1 that the two ends of bracing wire 4 are fixed on, the outer end of wind spring is consolidated It is scheduled on roller 1 and the inner is fixed in roller mount 11;The winding direction of the bracing wire 4 in the hand of spiral of wind spring and the roller 1 Unanimously.
For the ease of operation, the bottom of roller mount 11 is provided with sucker 5;Sucker 5 can adsorb roller mount 2 in planes such as blackboards On object.
Embodiment two
Such as Fig. 7 to Figure 11, the roller 1, turning rolls 21, bearing, roller mount 11, line mouth 3 and sucker 5 in the present embodiment and enforcement Technical scheme in example one is identical, except for the difference that:
Two roller mounts 2 are provided with support 6, and the upper end of support 6 offers the slotted eye of left and right insertion;Propping up in two roller mounts 2 Crossbeam 7 is provided between frame 6, the two ends of crossbeam 7 are arranged in slotted eye, and crossbeam 7 can horizontally slip in slotted eye;The upper end of support 6 Fixture 8 is provided with, fixture can be fixed on crossbeam 7 in slotted eye.The effect of crossbeam 7 is that two roller mounts 2 are fixed on into crossbeam 7 On be easy to operate or be easy to carry.
The middle part of crossbeam 7 is provided with penetration pipe 9, and the centre of penetration pipe 9 is provided with the passage 90 of left and right insertion, the side of passage 90 with The external world communicates, and the mid portion of bracing wire 4 passes through passage 90.
The present invention is so used:Two line mouths 3 are placed in the hyp bifocal for needing picture and using sucker 5 Absorption affinity is fixed on roller mount 2 on blackboard;Bracing wire 4 between two line mouths 3 is wound on paintbrush, is adjusted according to hyp parameter Position of the whole paintbrush between two line mouths 3, it is determined that keep position of the paintbrush in bracing wire 4 not move so after coordinate position Outside side shifting paintbrush and make the nib of paintbrush that lines are drawn on blackboard afterwards;Because the factor of the reply pulling force of wind spring makes bracing wire 4 are in all the time exceptionally straight state;Remain the whole bracing wire 4 of the paintbrush left and right sides all in taut during mobile paintbrush Straight state, thus when bracing wire 4 is stretched out and keep the whole bracing wire 4 of the paintbrush left and right sides all in exceptionally straight state then The line mouth 3 at left and right two ends extends the bracing wire of same length to inner side simultaneously, it is such in movement stretching bracing wire 4 with paintbrush black Any point on track drawn on plate to the difference of the distance between two line mouths of left and right is always definite value, the rail for so being drawn Trace bar is exactly the hyperbola of standard.When the hyperbola for needing the distance between picture focus very long is then using the side of embodiment one Case is carried out, and the scheme when the distance between hyperbola bifocal is less then using embodiment two is more convenient, because embodiment two In crossbeam two rollers can be kept an overall structures.
