Claims

[Scope of utility model registration request]

an energy storage spring consisting of a compression coil spring; a pair of first and second spring holders that contact each other in parallel and externally support the energy storage spring to compress it in the axial direction; 'A pair of guide grooves provided parallel to each other in the first and second spring holders along the axial direction of the spring, and a pair of guide grooves formed at the ends of the pair of guide grooves to be larger than the groove width. and this one
It has a shaft portion that fits into the pair of guide grooves from the pair of concave portions and a pot portion that engages with the outer side portions of the first and second spring holders, and is slidable between the first and second spring holders. and a connecting bottle connected to the first spring holder, the second spring holder applies pressure to the first spring holder to compress the second spring, and then releases the pressure to expand the second spring. An air breaker configured to close a pair of contacts via a second spring holder.
