Abstract:
A wire strainer including a body having a pair of arms between which a spool is mounted for rotation about an axis of rotation, said spool being rotatable in one direction to, in use, strain a wire coupled to the spool, a plurality of teeth rotatable with the spool, an engagement member formed from a length of stiff wire a part of which forms an engagement portion extending transversely of the body and engageable with a tooth or teeth of the spool to prevent rotation of the spool about the axis of rotation in a reverse direction, the engagement member being retained with the body for sliding movement relative to the spool, at least one projection formed by the length of stiff wire, said projection being slidingly engaged with a surface which is inclined relative to the axis of rotation of the spool to establish a biasing force when the engagement member is slidingly moved to disengage the engagement portion from said tooth or teeth of the spool whereby the engagement member is biased to move such that the engagement portion re-engages with the tooth or teeth of the spool.
