STRIKING DEVICE FOR FASTENING OF BRACKETS

摘要

FIELD: mechanical engineering. SUBSTANCE: this device for fastening of bracket has annular member made integral with mouth part of barrel 3 or in the form of nut 21 screwed on it and having protrusions 8 on bore end face for interaction with corresponding protrusions of brackets 11, and sleeve 8 spring-loaded in radial direction relative to barrel 3 located in annular member and having teeth on its working face end for interaction with hole of corresponding protrusion of bracket 11. In operation, barrel 3 is pressed against plane of object and at this moment disengaged is safety member of striking-release mechanism 2. Upon making shot, device is removed from fastened bracket 11. Under action of spring 10, sleeve 8 together with bush 14 occupies position which excludes any possibility of shot. EFFECT: higher efficiency. 1 cl, 7 dwg øøø1
