ROTEREND WERKEND KRACHTGEREEDSCHAP. |
摘要 |
Improved apparatus for retaining a detachable drive socket on the rotatable drive spindle of power tools such as an impact wrench. The spindle shank includes a longitudinal bore extending inward from its distal end for slideably supporting a plunger formed of a relatively hard, tough elastomer. A compressed coil spring biases the plunger forwardly toward the distal end of the shank while an elongated detent protrudes radially outward of the shank through a lateral bore in the shank side wall from a pivotal attachment in the plunger. With the plunger in its most forwardly biased position, the free end of the detent end protrudes radially outward past the shank periphery a distance sufficient to retain a socket in place on the spindle shank while interferring to prevent coupling or uncoupling therebetween. Displacing the plunger rearward against the spring effects a pivot of the detent for reducing its radial rise to enable coupling or uncoupling of the shank and socket to be effected. |
