Abstract: A device for adjusting a foot plate of a saw. The device includes a locking member with a fastener connected therewith for fastening the foot plate to a housing of a saw. A rotatable sleeve is connected to the locking member for rotating the locking member. A rotatable actuator assembly is pivotally connected to the rotatable sleeve for turning the rotatable sleeve. The rotatable sleeve and locking member can be engaged or disengaged with each other by effect of a biasing member or spring therebetween.  Therefore, when the rotatable sleeve and locking member are engaged with each other, the rotatable actuator assembly can be turned to rotate the rotatable sleeve, and the bolt which is fixed to the locking member is rotated consequently to adjust the tightness or looseness between the foot plate and housing of a saw. When the rotatable sleeve and locking member are disengaged from each other, the rotatable actuator assembly and the rotatable sleeve can be freely rotated to a position where they can be manually pressed into a recess or space within the foot plate and stored therein such that cutting will not be obstructed. With such an adjusting device, the position of the foot plate of a jigsaw can be easily adjusted in respect to the housing with no need of any other tools.
