Passive Retaining Lock System for a Hand Tool

A passive retaining lock apparatus for a hand tool, comprising:

• A) a pin retainer releasably and lockably receiving said pin mount member;
• B) a pin slot member having a pin slot entry and a pin slot with pin slot side walls configured to slidably receive a pin post along a first pair of first opposed surfaces having a first separation dimension while preventing a passage of said pin post along said pin slot side walls in an orientation of a second pair of second opposed surfaces having a second separation dimension;
• and
• C) a pin slot base opening dimensioned to receive said pin post and allow a rotation of said pin post along both said first and said second opposed surfaces and respective said first and said second separation dimensions.

A passive retaining lock system for a hand tool, comprising:

• A) a pin mount member attachable to a hand tool;
• I) said pin mount member having a pin post extending from a mounting support;
• B) a pin boss extending from a distal end of said pin post;
• I) said pin post having a first pair of first opposed surfaces having a first separation dimension;
• II) said pin post having a second pair of second opposed surfaces having a second separation dimension;
• said second separation dimension is larger than said first separation dimension;
• III) said first pair of opposed surfaces alternating with said second pair of opposed surfaces about an outer periphery of said pin post;
• IV) said pin boss having a pin boss outer dimension that is larger than both said first separation dimension and said second separation dimension;
• C) a pin retainer releasably and lockably receiving said pin mount member;
• D) a pin slot member having a pin slot entry and a pin slot with pin slot side walls configured to slidably receive said pin post along said first pair of first opposed surfaces having said first separation dimension while preventing a passage of said pin post along said pin slot side walls in an orientation of said second pair of second opposed surfaces having said second separation dimension;
• and
• E) a pin slot base opening dimensioned to receive said pin post and allow a rotation of said pin post along both said first and said second opposed surfaces and respective said first and said second separation dimensions.
