DEVICE FOR GUIDING A SPRING IN A CONTROL MECHANISM AND ELECTRICAL PROTECTION APPARATUS INCLUDING IT

The present invention relates to a device for guiding a spring belonging to a control mechanism, said device comprising two connecting rods capable of sliding with respect to each other and hingedly connected respectively by their free ends to two axes of which at least one of which is mechanically connected to a so-called maneuvering shaft and a compression spring supported by its two opposite ends respectively on the two aforementioned axes. This device is characterized in that it comprises means for slidingly guiding the two connecting rods with respect to one another, a closed oblong orifice (20) formed at one of the ends of each of the connecting rods, an orifice (21) formed at the other end of each of the connecting rods, these connecting rods being mounted head to tail, the closed oblong orifices (20) being capable of retaining the two axes (6, 7) respectively, the two open slots (21) being able to let the two axes (6, 7) escape respectively, so as to vary the guide stroke. 本发明涉及种在控制机构中引导弹簧的装置，该装置包括两个杆
