  • Socket retaining tool using a spring-loaded keeper sleeve
    Patent number: 9884413
    Abstract: A socket retaining tool for preventing separation of a socket from a drive shaft of a driving tool. A keeper sleeve is configured to accommodate insertion and reciprocal movement of a quick change adapter and a quick change sleeve under the action of a biasing member. The quick change adapter has a male end and an opposite female end. The male and female ends are constructed and arranged to be used with locking mechanisms such that the socket is connected to the male end, and the drive shaft is connected to the female end. A socket locking mechanism coupled to the male end is enclosed by the keeper sleeve, and a driver locking mechanism coupled to the female end is enclosed by the quick change sleeve, when the socket retaining tool is in a relaxed position, thereby avoiding unwanted release of the locking mechanisms.
