Patent ID: 8453333

Claim:
A hand-held hair cutting appliance comprising: a first blade including a plurality of shearing teeth defining a first cutting edge margin; a second blade including a plurality of shearing teeth defining a second cutting edge margin, wherein the second cutting edge margin is in sliding engagement with the first cutting edge margin; a drive assembly operatively connected to the second blade, the drive assembly being operable to impart reciprocating movement of the second blade relative to the first blade so that the shearing teeth of the second blade slide across the shearing teeth of the first blade; and a blade clamping device urging the second cutting edge margin in sliding engagement with the first cutting edge margin, the blade clamping device including a base, a clamping head, a resilient biasing member, and at least one bearing structure pivotably connecting the clamping head to the base such that the clamping head is configured for pivoting movement generally toward and generally away from the second blade about a pivot axis defined by the at least one bearing structure, wherein the biasing member resiliently biases said clamping head generally toward the second blade about said pivot axis into sliding engagement with the second blade, whereby the second blade is slidable relative to the clamping head during said reciprocating movement of the second blade relative to the first blade.
