Packaging and displaying device for a spanner

A packaging and displaying device for a spanner having a handle with first and second ends opposite to each other, and a clamping head disposed on the first end to apply torque in one direction only, said packaging and displaying device comprising:

• a backing mount member having front and rear walls opposite to each other in a first transverse direction, said front wall including a mounting portion with an annular bearing wall to define a through hole having a rotating axis and communicating said front wall with said rear wall, and a guiding portion opposite to said mounting portion in a longitudinal direction, said guiding portion defining an arc-shaped slot extending to communicate said front wall with said rear wall and spaced apart from said rotating axis in radial directions;
• an annular wheel member having a rim portion disposed to be rotatable relative to said annular bearing wall, and a hub portion disposed to surround said rotating axis;
• a ratchet mechanism disposed between said rim portion and said annular bearing wall to permit unidirectional rotation of said annular wheel member relative to said annular bearing wall;
• an anchoring member having an enlarged head portion disposed rearwardly of said rear wall, and a spindle portion with a proximate end disposed normal to said enlarged head portion and insertable into said hub portion to be rotated therewith, and a distal end extending from said proximate end in the first transverse direction to extend forwardly of said front wall;
• a clamped member including a socket end disposed to engage said distal end by press fitting in the first transverse direction, an annular spacer portion disposed outwardly of said socket end and to surround the rotating axis so as to face said front wall when said socket end engages said distal end, and a clamped portion opposite to said annular spacer portion in the first transverse direction, and adapted to be clamped by the clamping head;
• a handle holding member including
• a grip portion adapted to grip the second end of the handle so as to bring the clamping head to clamp said clamped portion,
• a guided key portion extending from said grip portion in the first transverse direction and rearward so as to be inserted through and guided by said arc-shaped slot when said clamped portion is rotated with said annular wheel member, and
• a first coupling end extending from said guided key portion in the first transverse direction and rearward so as to extend rearwardly of said rear wall;
• and
• a retaining member disposed rearwardly of said rear wall and including a second coupling end to engage said first coupling end so as to cooperate with said grip portion, to stabilize movement of said guided key portion in said arc-shaped slot.
