Claims16
A strapping tool comprising:
- a support comprising a foot;
- a tensioning assembly mounted to the support and movable relative to the foot of the support between a strap-tensioning position and a strap-insertion position, the tensioning assembly comprising a rotatable tension-wheel shaft and a tension wheel mounted to the tension-wheel shaft to rotate with the tension-wheel shaft;
- a motor operably connected to the tension-wheel shaft and configured to rotate the tension-wheel shaft in a first rotational direction;
- a retainer comprising a body having a tension-wheel-shaft engager, wherein the retainer is movable relative to the tension-wheel shaft between a release position and a retaining position;
- and
- a retainer-biasing element biasing the retainer to the retaining position,
- wherein when the retainer is in the release position spaced from the tensioning-wheel shaft, the retainer-biasing element forces the tension-wheel-shaft engager of the retainer into contact with a surface of the tension-wheel shaft of the tensioning assembly to enable the tension-wheel-shaft engager to further engage the tension-wheel shaft to retain the tensioning assembly in the strap-insertion position.
