Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown, the present invention is by L frame 1, wire wheel 2, crossbeam 3, wire ring 31, wheel frame 11, wheel axle 13, wire nozzle 12, telescoping wire 4, driving wire 5, pen cap 41 and coil spring 6.

[0021] The L-frame 1 is L-shaped, and there are two L-frames 1; the beam 3 is strip-shaped, and the two L-frames 1 are installed at both ends of the beam 3, and the two L-frames 1 are left-right symmetrical on the beam 3; the L-frame 1 can Move horizontally on the beam 3, and the two L frames 1 can also be fixed on the beam 3, so that the distance between the two L frames 1 can be adjusted; the horizontal part of the L frame 1 is provided with a wheel frame 11, and the wheel frame 11 A small hole is provided on the wheel frame 11, and the wheel frame 11 is provided with a wheel shaft 13 passing th...

Abstract

The invention discloses a dual-curve instrument. The dual-curve instrument structurally comprises an L-shaped frame, a spool, a cross beam, a wheel carrier, a wheel axle, line nozzles, a telescopic line, a transmission line, a pen loop and a coil spring. In use, the line nozzles are placed on two focuses of the dual curves, the pen loop is adjusted and fixed to a corresponding position according to parameters of the dual curves, then a pen is inserted into the pen loop for stretching the telescopic lines, the telescopic lines at two sides of the pen loop can be maintained under the tighter state all the time, therefore, the track of a pen point can be drawn by a pen during stretching, and the drawn track is of a standard dual-curve.

Description

technical field [0001] The invention relates to an instrument, in particular to a hyperbolic instrument. Background technique [0002] There are many instruments that can draw function curves in the field of mathematics, but there is no hyperbolic instrument that is intuitive, simple and easy to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hyperbolic instrument with simple structure and convenient operation. [0004] In order to solve the above technical problems, the technical solution of the present invention is as follows: [0005] A hyperbolic instrument, its structure includes an L frame, a wire wheel, a beam, a wheel frame, a wheel shaft, a wire mouth, a telescopic wire, a transmission wire, a pen case and a coil spring. [0006] The L-frame is L-shaped, and the L-frame is provided with two left-right symmetrical ones; the beam is strip-shaped, and the two L-frames are installed at both ends...
