The housing contains an output shaft which is connectable with nut sockets. The housing has a projecting support leg which acts as a counterpiece when a nut fitted in the socket is unscrewed by rotation of the crank. - The support leg comprises two parts, the outer of which is dropped to a position in which the free end is in engagement with the crank. The housing can thus be rotated as a unit when drawing nuts. |
