Abstract
A reaction arm mounting assembly comprises a first part and a second part, the first part being configured for attachment to a power tool and the second part is mounted on the first part. The mounting of the second part on the first part: permits sliding motion between the first and second part along an axis common to the first and second parts in a first sliding region and prevents rotation between the first and second member in the first sliding region; and permits rotation between the first and second members in a second sliding region.
Claims26
A power tool including a ratchet drive, the power tool comprising:
- a ratchet driven socket mounted for rotation within a ratchet drive housing;
- a fastener engagement member configured to resist rotation of a fastener engaged therewith;
- a mount for the fastener engagement member, the ratchet drive socket, the fastener engagement member and the mount being co-axial with each other, the fastener engagement member slidably mounted in the mount, wherein a shape and configuration of the mount and the fastener engagement member prevents relative rotation therebetween;
- an opening extending through the ratchet drive housing, the mount being slidably mounted in the opening and slidable through the opening to be positioned externally of the ratchet drive housing, wherein the shape and the configuration of the mount and the opening prevents relative rotation therebetween;
- biasing means arranged to exert a force urging the fastener engagement member along a common axis in a direction away from the opening in the ratchet drive housing;
- and
- a motion restrictor associated with the mount and limiting an extent of sliding motion of said mount through the opening.
A reaction arm mounting assembly comprising a first part and a second part, wherein the first part is configured for attachment to a power tool and the second part is mounted on the first part, and wherein the mounting of the second part on the first part:
- permits sliding motion between the first and second parts along an axis common to the first and second parts in a first sliding region and prevents rotation between the first and second parts in the first sliding region;
- and permits rotation between the first and second parts in a second sliding region, and further comprising biasing means configured to exert a biasing force on the first and second parts in a first direction, the biasing force urging the first and second parts to be in the first sliding region, and the biasing force being overcome to move the first and second parts in a second direction opposite the first direction to situate the first and second parts in the second sliding region.
A power tool having attached thereto a reaction arm mounting assembly comprising a first part and a second part, wherein the first part is configured for attachment to a power tool and a second part is mounted on the first part, and wherein the mounting of the second part on the first part:
- permits sliding motion between the first and second parts along an axis common to the first and second parts in a first sliding region and prevents rotation between the first and second parts in the first sliding region;
- and permits rotation between the first and second parts in a second sliding region, and further comprising biasing means configured to exert a biasing force on the first and second parts in a first direction, the biasing force urging the first and second parts to be in the first sliding region, and the biasing force being overcome to move the first and second parts in a second direction opposite the first direction to situate the first and second parts in the second sliding region.
