FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used for clamping tools at oscillating drive with drive shaft oscillating relative its lengthwise axis. Adapter drive side 12 has first fastener including lock for geometrical closure between adapter and tool. Said lock is composed of tight polygon, multiple locking parts arranged in circle concentric with adapter axis and multiple bulged ledges extending outward and having rounded tops and side concave rounding mated with adjacent ledges. Adapter lock element allows geometrical closure with mating lock at drive shaft. Adapter tool side 14 accommodates second fastener 18 for connection with tool. Its shape differs from first fastener 16 and id composed of multiple locks arranged in circle concentric with central axis 22, or multiple bulged ledges with rounded tops mated with adjacent ledged by side concave rounding.
EFFECT: attachment of tools to various-shape drive shafts.
