ABSTRACT:
The ratchet wrench of this invention is of two piece construction comprising a rigid pawl handle, and a spring strap cooperating with the pawl handle. The pawl handle has a squared-off end and is provided with two integral pawl teeth extending from one side, which are adapted to engage and drive a splined bit. The spring strap is u-shaped, extending over the squared end and pawl teeth of the handle, and along both sides of the handle. The spring strap is fixed to the handle sides at its two co-extending ends to hold the spring strap and pawl handle in substantially fixed position.
The closed end of the spring strap extends in an arc over the squared end of the pawl handle in such a way as to define a D-shaped opening, adapted to receive and to precisely position the splined bit.
