1. A power tool comprising:
- a tool body having a housing and a motor mounted in said housing, said motor including a rotary output;
a removable tool head; and
a retention mechanism for releasably securing said removable head to said tool housing, said retention mechanism including first and second arms, said first and second arms movable between a first position and a second position such that in said first position said first and second arms are oriented substantially parallel to one another and define an opening having a first dimension for retaining a portion of said tool head and in said second position said opening defined between said first and second arms has a second, larger dimension for receiving and removing said portion of said removable tool head from said tool housing, wherein the tool body defines an aperture providing access to the rotary output and further wherein the first and second arms are disposed within the aperture and the rotary output is disposed between the first and second arms.

Abstract
A power tool (10) includes a motor (22) mounted there within. The motor has an output (20) for engagement with an input of an attachment member (32) presented thereto. The coupling between the motor output (20) and the attachment member (32) is by a snap-fit coupling achieved by way of resiliently biased arms (56) within the tool engaging with an annular recess (54) formed on the attachment member (32).

14. A power tool comprising:
-
at least one attachment member; and
a body portion having a housing defining a handle and a motor mounted within the housing, the motor arranged to drive an output spindle of the tool, the body portion further defining an opening around the output spindle which opening accepts the at least one attachment member, the body portion including an engagement means within the opening and selectively engageable with a spigot formed on the attachment member, the engagement means movable between a first position to couple with the spigot and a second engagement position uncoupled from the spigot, the spigot defining an annular recess selectively cooperable with the engagement means to hold the at least one attachment member in engagement with the body portion, wherein the engagement means is normally biased to said first position to provide an opening of a first dimension to selectively retain the at least one attachment member one attachment member in engagement with the body portion. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
