An attachment system for tools includes a housing with a wall defining an open central region. The housing has a first slot and a second slot spaced from the first slot, each slot extending through the wall to the open central region. A rotating member is disposed in the open central region. A clip member has a clip protrusion with neck, head and tip portions, the neck portion sized to be slidably received in one of the slots. The tip portion is configured to engage the rotating member to cause it to rotate about a central longitudinal axis as the neck portion moves distally along one of the slots, causing a catch surface to align with the tip portion and a channel to align with a tip portion of a second clip member retained in the second slot, thereby retaining the first clip member and releasing the second clip member. |

1. An attachment system for hand-held tools comprising:
a housing with a proximal housing end portion, a distal housing end portion, and a peripheral wall defining an open central region within the housing, the peripheral wall having a first slot and a second slot spaced from the first slot, each with a predefined slot width and extending through the peripheral wall to the open central region, wherein the first slot and the second slot each has a proximal slot end and a distal slot end, the proximal slot end having a proximal slot end width that is greater than the predefined slot width; a rotating member disposed in the open central region and configured to rotate about the central longitudinal axis between a first position and a second position, wherein the rotating member comprises:
a member body rotatably connected to the housing and having a peripheral surface extending along the central longitudinal axis;a first body portion extending radially outward a predefined distance from the peripheral surface, the first body portion defining a catch surface facing distally, wherein the catch surface extends along a radial portion of the peripheral surface between a first portion end and a second portion end and defining a first body channel between the first portion end and the second portion end; anda second body portion extending radially outward from the peripheral surface and positioned distally of the first body portion, the second body portion defining a first sloping surface and a second sloping surface forming an apex positioned facing substantially a midpoint of first body channel between first body end and second body end of first body portion, wherein the first sloping surface and the second sloping surface each face proximally and extend distally in opposite peripheral directions along the peripheral surface from the apex; a clip member having a clip body with a housing-side surface and a clip protrusion disposed on the housing-side surface and having a neck portion, a head portion and a tip portion, the neck portion sized to be slidably received in one of the first slot and the second slot, the tip portion sized and configured to engage the first sloping surface or the second sloping surface and to rotate the rotating member about the central longitudinal axis as the neck portion moves along one of the first slot and second slot from the proximal slot end; wherein the tip portion moving distally in the first slot in engagement with the first sloping surface, causes the rotating member to rotate in a first direction about the central longitudinal axis, thereby causing the catch surface to align with the tip portion, and thereby causing the first body channel to align with a tip portion of a clip member retained in the second slot of the housing; and wherein the tip portion moving distally in the second slot in engagement with the second sloping surface causes the rotating member to rotate in a second direction about the central longitudinal axis, thereby causing the catch surface to align with the tip portion, and thereby causing the first member channel to align with a tip portion of a clip member retained by the housing along the first slot. |
