Quick hitch
A quick hitch(10) comprising; a movable hook (16) and a manually operated locking mechanism(12) this comprises, a sliding locking plate/panel(18) where the locking plate(18) is configured to retain the movable hook(16) in a closed position. The locking plate(18) is mounted with a torsion spring(fig.5, 26) which biases a rocking arm(20) that pivots on the same coupling pin(24) as the rotating hook(16). The retaining mechanism is biased to keep the hook(16) closed and is released mechanically by the use of a lever inserted into an aperture(fig.7a, 252). Excessive movement of the locking plate(16) is prevented by stoppers(30) on the internal walls of the coupler. The blocking plate(18) can be substantially H, Y, M or U shaped.
