A screw tool having a gear head, which has a freewheel gear, having an output shaft, which is inserted in a non-rotatable but displaceable manner in an output opening and can be moved to and fro between a right-hand screw position and a left-hand screw position in each case by use of axial displacement, wherein in each case a different end section of the output shaft projects out of the gear head, having at least one locking mechanism to secure the position of the output shaft in the respective screw position and/or around a screw output element on the output shaft. As a development which is advantageous for use, the at least one locking mechanism can be moved from a locking position to a release position by pressure on an actuation element arranged on the end face of the output shaft. |

1. A screw tool having a gear head which has a freewheel gear, having an output shaft which is inserted in a non-rotatable but displaceable manner in an output opening and can be displaced to and fro between a right-hand screw position and a left-hand screw position in each case by means of axial displacement, in each case a different end portion of the output shaft projecting out of the gear head, having at least one locking means to secure the position of the output shaft in the respective screw position and/or to secure a screw output element on the output shaft, the at least one locking means being held in a locking position by an unlatching slide disposed in an axial cavity of the output shaft and being displaceable from a locking position into a release position by pressure on actuation elements disposed on each end face of the output shaft, characterized in that the locking position is a form-fitting latching position that can only be released by axial pressure onto one of the two actuation elements so that in the locking position, the screw output element which, for example, is formed as a socket, cannot be removed from the output shaft. |
