Definitions

• the invention relates to a tool holder with at least one tool as an accessory to a power-operated device that fulfills a work function, into which the tool holder must be inserted during commissioning or use of the device, and from which it can be removed for use of the tool.
• a power-operated device is understood to mean any power-operated device, for example a simple work device operated by muscle power, in particular motor-driven or pressure-medium-operated devices.
• Various tools are required for the maintenance, cleaning or modification or attachment of an additional device.
• the tool screwdriver, wrench, spark plug wrench in fuel-operated devices, etc.
• the placement of one or more tools on the device entails the risk of loss, since the tool does not perform any function there.
• the brush cutter can also be used when the tool holder is removed. there is no compelling reason to return it to the storage location after using the tool.
• Work function includes only the area of actual work execution with a facility following the preparatory work to perform a job. This includes starting or switching on an engine of the facility, furthermore holding or guiding the facility during the work process, that is to say those minimum activities which are absolutely necessary even for the simplest execution of a facility to carry out the work.
• the object of the invention is to provide a tool holder with tools as an accessory to a power-operated device, without which, in its second type of use, even with the simplest design of a device, the work to be performed cannot be carried out.
• this object is achieved in that the removable tool holder is designed as an operating part to be used in the device for its commissioning or use, a component of the device which is absolutely necessary for the exclusive exercise of the work function.
• tools are therefore inseparable from an operating part which is absolutely necessary even in the simplest version.
• Assigned part of the facility The design of the facility itself remains essentially or completely unchanged. The training of separate recordings and additional elements after the State of the art does not apply.
• the tool holder in addition to the actual tool holder function, the tool holder, as a second function, therefore also fulfills the active function of a necessary operating part for mere commissioning or use, replacing the usual operating part. Design changes to the device are at most necessary to be able to easily assemble and disassemble the operating part formed by the tool carrier.
• the loss of the tool or tools is of course practically not possible, since after a repair with the tool that occurs during work or operation, the work can only be carried out again after the operating part has returned to the power-operated one Device has been installed.
• the tool or tools are designed so that they do not impair the usual basic shape of the operating part, so that there is no change in the handling and usability of the device.
• Tools for the continuous use of which tools are required, are called simple cutting or sawing tools, such as scythes, sickles, pull saws, hand saws or the like. With such tools, it is repeatedly necessary to sharpen the cutting edges or teeth.
