A CONNECTION DEVICE AND DRIVE ASSEMBLY FOR A CUTTING TOOL

摘要

The present invention provides a connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) to connect a first tool (80, 90) to a second tool (90,80), the connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) comprising at least one shell member 30 which clamps a first end to said first tool (80, 90) and a second end of said at least one shell member 30 to engage with said second tool (90,80), whereby relative rotation between said first tool and second tool is prevented, and axial separation of said first tool (80, 90) and second tool (90,80) is prevented or is assisted in being prevented. This results in a safer combination of said first tool (80, 90) and second tool (90,80), and allows for a one handed operation of the combination.

主权项

1. A connection tool or device to connect a first tool to a second tool, said connection tool or device comprising:
a first shell member and a second shell member which have a least a first end which is securable and or includes portions moveable with respect to each other, so as to clamp a first end of said first shell member and said second shell member to said first tool and a second end of said first shell member and said second shell member being adapted to interact or cooperate with said second tool, whereby relative rotation and axial separation between said first and second tool is prevented.
