Embodiment

[0032] Please combine figure 1 It should be understood that an elliptic hyperbolic plotter 100 includes a focus positioner 1, 2, a connecting rope 3, and a movement adjuster 45 that can slide along the connecting rope 3.

[0033] Please combine Figure 1-2 It should be understood that the connecting rope 3 is marked with a scale for accurately drawing ellipses or hyperbolas of different sizes. The two ends of the connecting rope 3 are connected with the focus positioners 1 and 2, and a drawing pen 7 is fixed to the moving bearing 4 of the moving adjuster 45 through the connecting sleeve 6. The drawing pen 7 can be a chalk or a pencil to meet the needs of classroom teaching or engineering drawing respectively.

[0034] Please combine figure 1 It should be understood that the focus positioner 1 includes a fixed part 13 for fixing the focus positioner on a blackboard or drawing paper, a rotating bearing 11, and a rotor 12. The focus positioner 2 includes a fixed part 23, a rotating b...

Abstract

The invention discloses an elliptic hyperbola plotter, which comprises: two focus locators, a connecting rope, and a movement regulator capable of sliding along the connecting rope, and the two ends of the connecting rope are respectively connected to the The focus locator is connected, and a drawing pen is fixed to the moving regulator. The invention has the advantage of being able to draw ellipses and hyperbolas conveniently.

Description

Technical field [0001] The invention relates to an elliptic hyperbola plotter. Background technique [0002] Drawing ellipse and hyperbola is a common task in engineering drawing and classroom teaching. However, the existing ruler drawing tools cannot meet the actual drawing needs. Engineers or teachers cannot draw accurate graphics because they do not have special drawing tools, which brings great inconvenience to production and teaching. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an ellipse and hyperbola plotter in order to overcome the defect of lack of special tools for drawing ellipse and hyperbola. [0004] The present invention solves the above technical problems through the following technical solutions: [0005] An elliptic hyperbolic plotter, comprising: two focus positioners, a connecting rope, and a movement adjuster capable of sliding along the connecting rope, characterized in that the two ends of the con...
