Abstract
A manually-actuated retention and release mechanism is disclosed for use with a blind threaded rivet setting tool. The mechanism has a cap with an internal screw thread which retains a drive screw immovably to a spindle such that axial or rotational movement of the spindle results in concomitant movement of the drive screw. The cap cooperates with a manually-actuable bar via series of serrations formed on the cap, each of which serrations is a latch point for the bar. Movement of the bar into or out of engagement with the serrations dictates whether or not the cap is locked in position.
Claims12
A retention and release mechanism for a power tool comprising:
- a mounting member, which mounting member carries a first external screwthread formed thereon and which mounting member includes a first coupling means;
- a drive screw, which drive screw carries a second external screwthread formed thereon and which drive screw includes a second coupling means, the second coupling means arranged for selective engagement with the first coupling means of the mounting member;
- a releasable locking member arranged to be selectively coupled to both the mounting means and the drive screw for immovable retention of the drive screw to the mounting means, and;
- a manually-actuable detent having locked and a released positions wherein, in the locked position, the detent restrains the releasable locking means to prevent uncoupling of the mounting means from the drive screw and in the released position, the detent allows uncoupling of the mounting means form the drive screw.
