FIELD: mechanics.
SUBSTANCE: invention relates to the device for selective interruption of rotation-and-reciprocation made up of a threaded longer element 114 and element 112 with internal thread in mesh with that of the aforesaid longer element. One of the aforesaid elements reciprocates when engaged with the other element till a position limited by end position 150. Reciprocating element 112, 114 can be subjected to instant deformations on reaching the aforesaid end position to get disengaged from the other element.
EFFECT: simpler design.
