FIELD: process engineering.
SUBSTANCE: clamp comprises male and female parts arranged for adjustment between clamped and unclamped positions. Note here that male part comprises first structural element with axis and front surface, retaining ledge and leveling ledge extending forward relative to retaining ledge front surface. Note that leveling ledge has axis spaced from retaining ledge by distance other than zero. Female part comprises second structural element with axis and rear surface, locking orifice extending forward relative to rear surface and having front end. Note that locking orifice comprises section of locating orifice and that of covering orifice. Note that covering orifice axis is spaced from locating orifice through first nonzero distance, leveling orifice extending forward with respect to locking orifice front end. Note that leveling orifice axis is spaced from covering orifice axis through nonzero second distance. Leveling section in unclamped state stops leveling orifice while locking ledge stops locating orifice of locking orifice without producing interference there between to allow removal of male element from female element. Leveling ledge as-clamped adjoins leveling orifice section, locking ledge covers section of covering orifice retaining section, retaining ledge adjoins locking orifice locking surface to produce interference fit between locking ledge and locking hole. Covering orifice section is locked at locking ledge without extra means.
EFFECT: better tool characteristics.
