Problems solved by technology
Although the implementation of this patent is feasible in terms of mechanical structure, and the operation is relatively simple, it uses the method of gear transmission to draw an ellipse, which cannot effectively adjust the parameters of the ellipse, and the types of ellipses drawn are too single, which is not conducive to universal

Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] like figure 1 Shown is a schematic diagram of the present invention, including: a first leg 1, a second leg 2, a handle 3, a connector 4, a first rotating shaft 5, a second rotating shaft 6, a hinge 7, a ferrule 8, a pencil 9, Buckle 10, nylon thread 11, small pulley 12. The handle 3 is located on the connecting head 4, and is detachably connected with the connecting head 4 through threads, which is convenient to hold when using. The lower part of the first leg 1 and the second leg 2 is a columnar structure, and the upper part is a gear-shaped structure, and the middle part of the gear has...

The invention discloses an ellipsograph which comprises a first supporting leg, a second supporting leg, a handle, a connecting head, a first rotating shaft, a second rotating shaft, a hinge, a clamping sleeve, a pencil, buckles, nylon fine lines, and small pulleys. The handle is connected with the connecting head through a thread, the first supporting leg and the second supporting leg are connected with the connecting head through the first rotating shaft and the second rotating shaft correspondingly, and the two small pulleys are fixed to the bottoms of the two supporting legs correspondingly; the clamping sleeve is connected with the connecting head through the hinge, and the pencil is detachably clamped in the clamping sleeve; and the two ends of the nylon fine lines penetrate throughthe buckles, and the two small pulleys are sleeved with the two ends of the nylon fine lines. According to the fact that the sum of the distances from a point on an ellipse to the two focuses on the ellipse is equal to a constant, the focal distance of the ellipse can be adjusted by adjusting the distances between the bottoms of the two supporting legs, the length of the major semi-axis of the ellipse is adjusted by adjusting the distance from a pencil tip to the bottom of any supporting leg, and any ellipse with known parameters can be drawn conveniently and quickly through the ellipsograph.
Description
technical field [0001] The invention relates to an ellipse gauge. Background technique [0002] In daily study and work, it is often necessary to draw an ellipse. In some occasions, the hand-painted method can be used, and the graphics are very inaccurate; in some occasions, such as mechanical drawing, the approximate drawing method is used, and the drawing method is extremely cumbersome; The situation makes the drawing of ellipses in daily life a big trouble. How to draw an ellipse with known parameters conveniently and quickly is an urgent problem to be solved. The research on ellipse gauges has a long history, but until now, the existing disclosed related patents have problems such as complex structure and inconvenient use, and have not been popularized. [0003] For example, the patent with the authorized announcement number CN 103950326 B discloses an "ellipse gauge": the ellipse is drawn by gear transmission, and the deformation between parts is small. Angle adjustme...
