The device comprises a compass supporting part and a wire sleeve;
the compass supporting part comprises a supporting rod, and locking members are respectively arranged at two ends of the supporting rod;
preferably, the support rod is in a straight pipe form;
the locking component is integrally in a channel steel form and comprises a connecting plate and two side plates, wherein the connecting plate is sequentially connected with the two side plates;
the side plate is provided with a locking hole groove which is a screw hole, and a bolt is screwed in the locking hole groove; namely, the two locking members are integrally assembled on the two compass legs in a hard limit mode;
the side plate is provided with a V-shaped groove; a wire sleeve is sleeved in the V-shaped grooves of the two locking members.
That is, the two supporting legs of the compass are propped up and locked through the compass supporting part, then the chalk is placed in the linear sleeve, the linear sleeve is tightly expanded by the chalk, and the drawing of an ellipse can be completed by encircling and drawing one circle in the constraint of the linear sleeve, namely, the visual demonstration of the concept of the ellipse is completed.
Furthermore, the supporting rod is of a pipe sleeve structure, and a hard limit bolt is arranged on the outer sleeve in a penetrating way. The effect achieved in this way is that the locking distance of the two legs can be adjusted.
Further, the locking component is hinged with the supporting rod through the lug plate.
Furthermore, the chalk sleeve is movably arranged on the wire sleeve, the chalk sleeve is in a round sleeve shape, and a wire slot is arranged on the barrel body in a surrounding mode.
Further, in the side plates on both sides of the locking member, the height of one side plate is higher than that of the other side plate, and the V-shaped groove is formed in the side plate on the higher side. The stroke of the wire sleeve is standardized, and the situation that ellipse drawing is not formed is avoided.
The beneficial effects of the utility model are as follows: the utility model is based on the compass accessory in the prior art, and can complete drawing of ellipse after assembly and connection. Compared with the prior art, the ellipse drawing method has the advantages that for the ellipse concept, namely, the curve obtained by a plane truncated secondary conical surface, the demonstration effect is very visual, and meanwhile, the condition that the ellipse is drawn in a non-forming mode due to displacement of the compass support legs is effectively avoided in the drawing process. In particular, the equipment has low cost, simple structure and great teaching popularization value.

Detailed Description
Referring to fig. 1, 2 and 3, the auxiliary ellipse drawing tool of the present utility model includes a compass supporting part and a wire sleeve 3;
the compass supporting part comprises a supporting rod 2, and locking members 1 are respectively arranged at two ends of the supporting rod 2;
preferably, the support rod 2 is in a straight pipe form;
the whole locking member 1 is in a channel steel form and comprises a connecting plate 5 and two side plates 6, and the connecting plate 5 is sequentially connected with the two side plates 6;
the side plate 6 is provided with a locking hole groove which is a screw hole, and a bolt is screwed in the locking hole groove; namely, the two locking members 1 are integrally assembled on the two compass legs in a hard limit mode;
