Tool holder device for e.g. motor vehicle to support e.g. cut-off wheel, has coupling and/or decoupling units cooperate with each other such that one of coupling and/or decoupling units causes automatic connection of support to section

摘要

The device has coupling and/or decoupling units cooperate with each other such that one of the coupling and/or decoupling units causes automatic connection of a trolley support (5) to a section (2) and automatic disconnection of a tool holder trolley (4) of the trolley support, and allows displacement of the tool holder trolley on the section independently of the support when the tool holder trolley is moved from another section (3) toward the former section. The coupling and/or decoupling units are formed of a hook, a control rod, stops and a ratchet element.
