Abstract

The invention discloses a tool gauge for drawing a hyperbola, and relates to the technical field of tool gauges. The tool gauge for drawing the hyperbola comprises a sliding rod, a fixed-origin column and fixed-focus columns. A T-shaped slot is formed in one surface of the sliding rod and matched with the fixed-focus columns. A through hole is formed in one surface of the sliding rod and matched with the fixed-origin column. Two discs are fixed to one surface of each fixed-focus column and connected in series through a cylinder. A first blind hole is formed in one surface of each cylinder. The fixed-origin column comprises a bolt, a threaded blind hole bolt, a nut and a fixed-origin needle, wherein the bolt is matched with the threaded blind hole bolt, the nut is fixed to one end of the threaded blind hole bolt, and a second bind hole is formed in one surface of the threaded blind hole bolt; and a fixed-origin needle is fixed to one surface of the threaded blind hole bolt. A thin thread is tied on the fixed-origin column and connected with a pencil through the fixed-focus columns. According to the tool gauge for drawing the hyperbola, the lengths of the portions, between the pencil and the two fixed-focus columns, of the thin thread are set as PF1 and PF2, the fixed-origin column rotates, and thus the problem that the hyperbola is difficult to draw is solved.

Description

technical field [0001] The invention belongs to the technical field of tool gauges, in particular to a tool gauge for making hyperbolas. Background technique [0002] In the study of mathematics, especially the study of geometric knowledge, it is often necessary to draw geometric figures. For the drawing of graphic patterns, a specific tool must be used. Most of the tools used are rulers and compasses. The function is also relatively simple, and the making of graphics is relatively simple. There is no drawing tool for the drawing of hyperbolas. There is no easy way to make a hyperbola graph directly, and it adds some difficulty when a hyperbola graph is required. [0003] In order to achieve the above object, the present invention adopts a new way, by setting the distance between the two fixed focus columns and the thin line length PF between the pencil and the two fixed focus columns 1 、PF 2 , to control the rotation of the bolt on the fixed origin column, and the rotati...
