An actuating mechanism for a tool includes a shell and a switch actuator. The shell includes a slot defined therein between two edges and at least one boss formed thereon. The switch actuator includes two hooks to be inserted through the slot for engagement with the two edges and at least one recess defined therein for receiving the at least one boss in a releasable manner. The switch actuator includes two tabs extending from a side thereof for insertion in the slot. The switch actuator includes a driving element extending from a side thereof through the slot for driving another element of the tool. The switch actuator includes a slot defined therein between two edges, at least one of which defines the at least one recess for receiving the at least one boss. The at least one boss is a semi-cylinder, and the at least one recess is semicircular. The shell includes two bosses, and each of the edges by the slot of the switch actuator defines a recess for receiving one of the bosses.
