Document Type and Number:
Japanese Patent JP6802919
Kind Code:
B2
Abstract:
A quick clamping device for a portable machine tool, in particular an angle grinder, includes at least one output shaft, at least one clamping unit, at least one operating unit, and at least one securing unit. The clamping unit, for the purpose of fixing an insert bit to the output shaft without using tools, includes at least one clamping element for applying a clamping force to the bit in a clamping position. The operating unit moves the clamping element into the clamping position and/or into a release position in which the insert bit can be removed from the clamping unit and/or the output shaft. The securing unit is designed to prevent movement of the clamping element from the clamping position into the release position at least under the action of a force decoupled from the operating unit and acting on the clamping element in the direction of the release position.
