Oscillating tool
A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.
1 . A power tool, comprising:
a housing;
a motor housed in the housing;
a spindle mounted in the housing and drivable in an oscillating motion by the motor about an output axis;
a clamp assembly arranged at an end of the spindle, the clamp assembly comprising a first clamping member and a second clamping member, wherein the first clamping member and the second clamping member are configured to hold an accessory therebetween;
a biasing member providing a clamping force for the clamp assembly; and
a user-operable actuator for operating the clamp assembly, wherein:
the clamp assembly is configured to permit removal of the accessory from the clamp assembly while the first clamping member and the second clamping member remain coupled to the power tool;
the clamp assembly is configured such that the accessory can be retained by the clamp assembly in a clamped condition in a plurality of rotational positions including at least a first rotational position, a second rotational position, a third rotational position, and a fourth rotational position;
the user-operable actuator is a lever;
the lever pivots about a pivot axis;
the pivot axis is transverse to the output axis;
the first rotational position is spaced ninety degrees from the second rotational position;
the first rotational position is spaced ninety degrees from the fourth rotational position;
the first rotational position is spaced one-hundred and eighty degrees from the third rotational position;
the fourth rotational position is spaced ninety degrees from the third rotational position; and
the fourth rotational position is spaced one-hundred and eighty degrees from the second rotational position.
2 . The power tool of claim 1 , wherein the spindle comprises a first section with a first diameter and a second section with a second diameter different than the first diameter,
the power tool further comprising a first bearing disposed on the first section of the spindle and a second bearing disposed on the second section of the spindle.
3 . The power tool of claim 2 , wherein the motor drives the spindle through a drive fork, and
wherein the drive fork engages the spindle between the first bearing and the second bearing.
4 . The power tool of claim 1 , wherein the first clamping member comprises a through hole.
5 . The power tool of claim 1 , wherein the clamp assembly is configured to operate in a tool-free manner.
6 . The power tool of claim 5 , wherein the first clamping member is outside of the housing, and
wherein the second clamping member is outside of the housing.
7 . The power tool of claim 5 , wherein one of the first clamping member and the second clamping member include a plurality of protrusions configured to rotationally locate the accessory in the clamp assembly, and
wherein the plurality of protrusions are unevenly spaced around the one of the first clamping member and the second clamping member.
