Abstract

L'invention concerne un tournevis présentant un dispositif de verrouillage dont le sens peut être inversé. Ce tournevis comprend deux mécanismes à roue libre individuels (4, 5), qui assurent respectivement un verrouillage dans un sens de rotation et permettent un fonctionnement en roue libre dans un sens de rotation opposé et qui sont situés axialement l'un derrière l'autre dans le boîtier du tournevis, dans des sens d'opération opposés. Ces mécanismes à roue libre peuvent être accouplés en alternance à un élément entraîné central (2) sous l'effet d'un mouvement d'accouplement dans le sens axial. Un manchon d'accouplement (11), placé de manière bloquée en rotation mais de façon à pouvoir se déplacer axialement sur l'élément entraîné (2), présente un profilé d'accouplement (12, 19) faisant saillie radialement vers l'extérieur, qui peut en alternance être mis en contact avec des profilés correspondants (13) de douilles intérieures (10) des mécanismes à roue libre individuels (4, 5) et être désengagé desdits profilés correspondants.
