The frame comprises a connecting hole and the equipment comprises a connecting pin for insertion into the hole in the frame during positioning. The hole opens into a surface of the frame and has an enlarged portion, which preferably is diverging towards the surface of the frame, closest to the surface and a cylindrical portion beyond the diverging portion, whereas the connecting pin has a cross sectional dimension which is equal to or slightly smaller than the cross sectional dimension of the cylindrical portion in the hole. |
