Abstract
A aspects of one or more exemplary implementations, disclosed is a plastic tool mount and system with a tool connector head with a back side, nose and distal end of the nose; a shaft guide having a channel is formed within the head open at the distal end of the nose; the channel further having a raised bump section of plastic extending from a wall of the shaft guide into the shaft guide channel; and, wherein the diameter of the shaft guide channel at the location of the raised bump is diminished.
Claims12
A tool mounting method comprising:
- inserting a tool with a metal square shaft having a free end into a generally square shaft guide with four orthogonal walls of a plastic tool connector;
- during insertion pass the free end over a raised section of a plastic bump extending from a wall of said shaft guide into the shaft guide whereby a portion of the shaft guide near the location of the raised section is diminished and has a diameter small than the diameter of the metal square shaft;
- and,
- whereby upon insertion of said free end into the shaft guide a portion of said raised section is removed by the free end forming a pressure fit between the residual of the plastic bump, shaft guide and shaft.

A tool mounting method, the method comprising:
- forming a plastic tool connector head with a nose having a generally square shaft guide with four orthogonal walls formed within said head and opening at the distal end of the nose;
- forming first and second raised sections of plastic bumps extending from at least one wall of the shaft guide into the shaft guide whereby a portion of the shaft guide near the location of each raised section is diminished;
- inserting a square shaft with a diameter larger than the diminished section of the shaft guide into the shaft guide than said shaft guide;
- and,
- during insertion of the shaft into the shaft guide a portion of each of said raised section is removed by the free end forming a pressure fit between the residual of the plastic bumps, shaft guide and shaft.
