Abstract

The invention discloses an accessory clamping mechanism which is used for clamping an accessory on the flange of the working arbor of a power tool, and the working arbor is provided with a first longitudinal axis. The accessory clamping mechanism comprises a fastening flange, a driving component used for enabling the fastening flange to move between a releasing position and a clamping position, a push component connected with the fastening flange and a first elastic piece. The driving component comprises a pivot arranged on the shell body of the power tool and a driving piece pivoting between a first position and a second position around the pivot. On the first position, the fastening flange is arranged on the clamping position, and the accessory is clamped between a mandril flange and the fastening flange. On the second position, the fastening flange is arranged on the releasing position, and the accessory can be taken out between the mandril flange and the fastening flange. The fastening flange is pressed towards the clamping position through the first elastic piece, and the pivot is arranged between the user operating part of the driving piece and the first longitudinal axis. The invention further provides a power tool with the accessory clamping mechanism.

Description

technical field [0001] The present invention relates to a clamping mechanism, in particular to a clamping mechanism for releasably securing an accessory to a work spindle; the invention also relates to a power tool with such a clamping mechanism, in particular to a A power tool with a clamping mechanism for releasably securing an accessory to a work spindle.
