Abstract
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.
Claims13
A tool mounting system comprising:
- a plastic tool connector head with a nose and back side;
- a generally square shaft guide with four orthogonal walls and an open distal end formed within said head;
- 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;
- a tool with a metal square shaft having a free end and said shaft being of a diameter less than said shaft guide but greater than said diminished shaft guide;
- 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 plastic tool connector head with a back side and a nose;
- a generally square shaft guide with four orthogonal walls formed within said head and opening at the distal end of the nose;
- a square shaft with a diameter less than said shaft guide having a free end;
- a first and second of raised section forming plastic bumps extending from walls of said shaft guide into the shaft guide whereby a portion of the shaft guide near the location of each raised section is diminished;
- upon insertion of the shaft into the shaft guide each bump a tool with a metal shaft pressure fit against the residuals in said shaft guide;
- and,
- whereby upon insertion of said free end into the shaft guide a portion of each of said raised sections is removed by the free end forming a pressure fit between the residual of the plastic bumps, shaft guide and shaft.
