Abstract
A ratcheting tool includes a head including an end with an arcuate toothed face and a handle having an end defining a compartment for pivotal connection with the end of the head. The handle includes a longitudinal hole having an inner end and an outer end communicated with the compartment. The handle further includes a transverse hole communicated with the inner end of the longitudinal hole. A catch is mounted in the longitudinal hole and includes a first end with an arcuate toothed surface and a second end. A push button is mounted in the transverse hole and includes a stem, the stem including a relatively higher portion and a relatively lower portion. An elastic member biases the push button to a retaining position in which the second end of the catch engages with the relatively higher portion of the stem such that the arcuate toothed surface of the catch is biased to engage with the arcuate toothed face of the head, thereby retaining the head in an angular position relative to the handle. When the push button is pushed, the second end of the catch is disengaged from the relatively higher portion of the stem such that the arcuate toothed surface of the catch is disengaged from th…
