Packaging and displaying device for a spanner

Claim 1

A packaging and displaying device for a spanner which includes a handle with proximate and distal ends opposite to each other in a first longitudinal direction, a clamping head disposed on the proximate end and having a stationary jaw portion and a movable jaw portion that is biased to turn towards the stationary jaw portion about a pivot axis transverse to the first longitudinal direction, and a pulling rod disposed to be pulled in the first longitudinal direction to turn the movable jaw portion away from the stationary jaw portion, said packaging and displaying device comprising: a backing mount member having front and rear walls opposite to each other in a transverse direction, said front wall including a mounting portion which has an annular bearing wall to define a through hole with a rotating axis for communicating with said rear wall, and a guiding portion opposite to said mounting portion in a second longitudinal direction; 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 the rotating axis; a ratchet toothed member disposed between said rim portion and said annular bearing wall to permit uni-directional rotation of said annular wheel member relative to said annular bearing wall; an anchoring member having an enlarged head portion which is disposed rearwardly of and which is in frictional contact with said rear wall of said backing mount member, and a spindle portion which has a proximate end disposed normal to said enlarged head portion and insertable into and rotatable with said hub portion, and a distal end extending from said proximate end in the transverse direction to extend forwardly of said front wall of said backing mount member; a clamped member including a socket end disposed to engage said distal end of said spindle portion of said anchoring member by press fitting in the transverse direction, an annular mount portion disposed outwardly of said socket end to surround the rotating axis, and a clamped portion disposed opposite to said annular mount portion in the transverse direction, and adapted to be clamped by the clamping head of the spanner to coincide the rotating axis with the pivot axis when the movable jaw portion is biased to turn towards the stationary jaw portion; a spanner holding member including forward and rearward walls opposite to each other in the transverse direction, and having an anchored end portion defining an anchored hole which extends through said forward and rearward walls so as to be sleeved on and to be rotated with said annular mount portion of said clamped member about the rotating axis, and a stabilizing end portion opposite to said anchored end portion in the second longitudinal direction; a securing member disposed on said forward wall at said stabilizing end portion, and adapted to hinder the distal end of the handle of the spanner from moving away from said forward wall in the transverse direction; and a key and keyway arrangement disposed between said rearward wall at said stabilizing end portion of said spanner holding member and said front wall at said guiding portion of said backing mount member so as stabilize swinging movement of said spanner holding member relative to said backing mount member when said clamped member rotates with said annular wheel member.
