Nail hammer with independent claw assemblies - has striker coacting with rotary member for rotating one set of claws

摘要

The nail hammer comprises a drive axis (6), an anvil (4) with hammer claws (5) and a striker cooperating with a rotating member (10) attached to axis, second claws (15) are attached to the rotary member so that these claws can turn together with the member and move axially relative to it. The hammer is equipped with a device (27, 22) to prevent these claws working with the anvil claws before the striker has gained a certain speed of rotation. The rotary member and anvil are arranged axially stationary, while the striker claws can move freely relative to the member when the striker accelerates.
