Abstract
A screwdriver 1 includes a hook 7 which is configured to fit in an accommodating recess 20 grooved in a motor housing 4 and a handle cover 5. The hook 7 includes an extending portion 8 for being accommodated in a first groove 21 and a base block 9 for being accommodated in a second groove 22. The base block 9 is provided with a pair of slide plates 10 which in turn includes retainer flanges 11 at its free ends. To draw out the hook 7, it is manually pulled up at the top end of the extending portion 8 and slid rearward so that the retainer flanges 11 of the slide plates 10 enter support slots 27 provided at the rear of the second groove 22. Simultaneously, a support plate 12 of the base block 9 abut the top wall 5a of the handle cover 5. In this drawn-out position, as the retainer flanges 11 interfere with the edges of the support slots 27, the hook 7 is prevented from slipping out the screwdriver 1 and secured on the handle cover 5 outside the accommodating recess 20.
