УЗЕЛ НАКОНЕЧНИКА ЗЕМЛЕРОЙНОГО ЗУБА/ПЕРЕХОДНОГО ЭЛЕМЕНТА С СОЕДИНИТЕЛЬНОЙ КОНСТРУКЦИЕЙ, ОБЕСПЕЧИВАЮЩЕЙ БЛОКИРОВКУ ВРАЩЕНИЯ

摘要

A replaceable excavating tooth point is telescoped onto an adapter nose and releasably retained thereon by an elongated, flat connector member having an untapered side periphery. The connector member longitudinally extends through aligned point and connector openings and blocks forward removal of the point from the adapter nose. A transverse point sidewall abutment surface facing one end of the installed connector member prevents it from moving outwardly through one of the point openings, and a rotatable lock member carried by the other end of the connector member and engageable with a groove in the other point opening releasably prevents the connector member from moving outwardly through the grooved point opening. A detent structure releasably holds the lock member in locking and unlocking orientations in which the lock member is prevented from moving parallel to the length of the connector member.
