1. A tool for opening and closing a transducer housing having two housing parts, a base body and a lid, that are coupleable with each other via a rotational coupling, wherein the tool comprises:
a base portion forming a bowl for receiving the transducer housing and preventing a rotation of the base body of the transducer housing relative to the base portion of the tool around an axial direction of the tool; and an upper portion that is separate from the base portion and may be attached to the base portion, wherein a movement of the upper portion relative to the base portion in a radial direction, which is perpendicular to the axial direction, is mechanically prevented when the upper portion is attached to the base portion; wherein the base portion comprises a first engagement member and wherein the upper portion comprises a second engagement member which engages with the first engagement member when the upper portion is attached to the base portion, wherein the upper portion further comprises a driving pin having a driving area for contacting a corresponding contact area of the lid of the transducer housing for causing the lid of the transducer housing to move relative to the base body of the transducer housing in order to open or close the rotational coupling upon a rotational movement of the upper portion relative to the base portion around the axial direction; and wherein an engagement of the second engagement member with the first engagement member prevents a movement of the upper portion including the driving pin relative to the base portion along the axial direction during a contact between the driving area of the driving pin and the contact area of the lid of the transducer housing. |
