ABSTRACT:
There is provided a socket mechanism for rotating a bolt or nut, or like fastening piece, that is used with a vertical type powered bolt
ut driving apparatus. The socket mechanism has a spindle that can be coupled to a drive shaft of the driving apparatus, a socket for engaging with the bolt or nut having a guide at the bottom end thereof for facilitating the object bolt or nut to slip into the socket, a socket holding core having a downwardly tapered mid section, and a generally cylindrically-shaped core holder fixedly attached to the spindle having a bottom opening. The socket is fixedly attached to the low end of the socket holding core. The tapered part of the socket holding core freely lies on the rim of the bottom opening of the core holder in a manner that a lower part of the core and the socket are below the opening and suspending from the core holder. The socket holding core and the spindle are flexibly coupled to each other so that a rotational power is transmitted from the spindle to the core but permitting lateral and angular misalignment therebetween, whereby a reasonable amount of lateral misalignment between the object fastening piece and the drive shaft of the driving apparatus is permitted.
