摘要： A multipurpose air tool (1) having a handle (2) to which a head (3) can be removably attached. The head (3) has attached thereto various tools such as a face plate (4) and replaceable nozzles (5). The head (3) is interlocked to the handle (2) by a spigot (19) and bayonet connection (21, 23, 34). A safety interlock (16) prevents operation of the trigger (15) and valve (12) unless the head (3) is correctly positioned on the handle (1).
