Adaptor for rotary impact tool

摘要

An adaptor 1 for connecting between an output shaft 40 of a rotary impact tool 2 and tool bit 3 has a body 10, comprising a first end wall 111 and a second end wall 121. A square aperture 112 in the first wall extends axially through body 10 towards wall 121 and a smaller calibre hexagonal aperture extends axially through the same towards wall 111. Magnet 20 located proximate the hexagonal aperture and spring clip 124, 125 located within it, both serve to retain the tool bit. The adapter is secured to output shaft 40 by means of two spring loaded bolts (not shown), located within the shaft and extending to engage with aperture 14 which runs transverse to and intersects with the square aperture.
