FIELD: mining, particularly excavation equipment for detachable connection of replaceable tooth crown in earth-shifting machine.
SUBSTANCE: device comprises the first and the second telescopically joined members, aligned orifices formed in the members and adapted for connector receiving and connection finger unit for forced retention of the first and the second members so that the members are telescopically arranged one relatively another. Connection finger unit comprises body, fixing member and resilient stop member. The body is arranged in the aligned orifices so that the body may be removed therefrom. The connector prevents separation of the first member from the second one. The body also has channel opened in outer surface thereof and having non-round side surface section. Fixing member is arranged in channel and limited by side surface section. The fixing member may rotate with respect to the body from fixing position into releasing position and in reverse direction. Resilient stop member is connected with fixing member so that the stop member may rotate together with fixing member. The stop member is adapted to retain fixing member in fixing position. The stop member has periphery delimiting fixing member. The periphery is slidably joined with non-round side surface section so that the periphery and the side surface are mutually complementary.
EFFECT: increased efficiency of connection unit for wearing and support member connection.
