Exchangeable work assembly of a screwdriver and the method of using the assembly

摘要

An exchangeable work assembly of a screwdriver includes a connector partially received in the shank of the screwdriver and including a polygonal block and the polygonal stub longitudinally extending from one end of the polygonal block. The polygonal stub is received in the shank of the screwdriver. A first detaching block has a polygonal hole defined to selectively receive the polygonal block of the connector for detaching the connector from the shank after rotating. A barrel is connected to the polygonal block of the connector and has a polygonal hole defined to receive the polygonal block of the connector. A second detaching block is selectively connected to the barrel and has a hole defined to partially receive the barrel for detaching the barrel from the connector after rotating.
