|ствуюи1вго лепестка, причем центральный шарик 6 находитс  в посто нном контакте с дополнительными шариками 7, благодар  чему осевое усилие от штока 4 распредел етс  равномерно между лепестками и выступами . Каждый лепесток независимо от другого перемешаетс  до соприкосновени  г поверхностью закрепл емой детали, что уменыиает возможность смещени  деталей на оправке.The lobe of the petal, and the central ball 6 is in constant contact with the additional balls 7, whereby the axial force from the rod 4 is distributed evenly between the petals and the projections. Each petal, independently of the other, is mixed until the surface of the fixed part touches, which reduces the possibility of displacement of parts on the mandrel.

В момент соприкосновени  с поверхностью детали лепестки изгибаютс , принима  форму отверсти  детали, чему способствует наличие продольных канавок в зоне ,меж у двум  выступами. Причем - посто н|ный магнит преп тствует выпадению шариков и облегчает сборку и разборку.At the moment of contact with the surface of the part, the petals bend, taking the shape of the hole of the part, which is facilitated by the presence of longitudinal grooves in the zone between the two protrusions. Moreover, a permanent magnet prevents the balls from falling out and facilitates assembly and disassembly.
