Abstract (en)
A multifunctional tool and a rapid replacement structure thereof, comprise an output shaft assembly. An elastic chuck (16) capable of moving axially is arranged in the output shaft assembly. A locking shaft (10) is arranged in the elastic chuck (16) and driven by an elastic assembly to move axially in the elastic chuck (16), thus expansion opening and closing of the elastic chuck (16) are achieved. The present invention controls the axial sliding of the output shaft assembly and the locking shaft assembly by rotating a knob at the head of the machine, thus the saw web is controlled to be loosened or clamped and the rapid replacement function is achieved.
