Shaft Securing Mechanism For A Tool

摘要

A securing mechanism is provided for a tool that allows for the attachment and release of the shafts of a variety of implements from the tool. The mechanism has a construction that provides an easily releasable, but secure engagement of the implement shaft within the mechanism while also having an alignment feature which engages the implement at multiple locations when engaged with the mechanism to maintain the alignment and concentricity of the implement shaft with regard to the mechanism and the tool when in use.

1. A securing mechanism for attaching the shaft of an implement to a tool, the mechanism comprising:
a) a socket adapted to be secured to the tool, the socket including at least one groove disposed on an interior surface of the socket and engageable with the shaft to maintain the alignment of the shaft with the mechanism; b) a locking sleeve including a central passage aligned with the socket and having a locking surface therein; c) a release collar aligned and inserted within the passage of the locking sleeve, the collar including a locking member selectively engageable with the locking surface and adapted to engage the shaft; and d) a biasing member disposed within the passage between the socket and the collar to bias the locking member into engagement with the locking surface.
