Beschreibung
Zusammenfassung:	The invention relates to nuts, in particular to a circular-truncated-cone-shaped anti-theft nut. The circular-truncated-cone-shaped anti-theft nut comprises a nut body and is characterized in that the nut body is of a circular-truncated-cone-shaped structure, tightening grooves which become deeper and deeper in the tightening direction are formed in the side potion of the nut body, and the tightening grooves occupy part of the side portion in the length direction. The anti-theft nut of the structure has the advantages of being simple in structure, low in manufacturing cost and good in anti-theft effect. 本发明涉及螺母，具体地说是涉及是一种圆台形防盗螺母。圆台形防盗螺母，包括螺母本体，其特征是：所述的螺母本体是圆台形的结构，螺母本体的侧部具有沿上紧方向由浅变深的上紧槽。所述的上紧槽占侧部长度的一部分。这样结构的防盗螺栓具有结构简单、制造成本低、防盗效果的优点。
