A tool-holding device (11) for holding a tool (13) on a work machine with a retaining unit (20) and with a lock unit (30). The lock unit (30) can be transferred from a receiving position into a fixing position, and the retaining unit (20) comprises a receiving section (21) for holding the lock unit (30) at least in sections. The lock unit (30) comprises a tool-holding section (33) for holding a tool (13) in a pre-positioned manner. A work machine with this tool-holding device and a method for positioning a tool (13) on a work machine are also disclosed.

Devices, systems and methods for holding devices, including tool holders and/or associated apparatus, that can be attached to various driving mechanisms. Various embodiments can include one or more canted, or slanted, coil springs that are capable of forming to various shapes by the application of a controlled force.

A tool holder comprising a base element, a deformable receiver for clamping a tool and at least one locking element configured for preventing an axial extraction of the tool from the tool holder through engaging a corresponding opposite element at the tool, wherein the at least one locking element is integrally configured in one piece with the receiver.

A sleeve device includes a main unit having a sleeve with an open end face, a receiving space intercommunicating with the open end face, and a radial hole. An engaging member extends into the receiving space. A fixing member is mounted to an end of the receiving space opposite to the open end face. A pressing member is slideably received in the receiving space for pressing against the fixing member. The pressing member includes a cylindrical portion, an abutting portion, and a pressing portion, with the abutting portion and the pressing portion disposed on two ends of the cylindrical portion. A positioning member is slideably received in the radial hole for selectively pressing against an outer periphery of the cylindrical portion or the pressing portion. A ring is rotatably mounted around the sleeve and includes an inner periphery and a first recessed portion for selectively abutting the positioning member.
