摘要： A stepwise adjustable square for use in carpentry, including: a stock; and a blade rotatable relative to the stock around an axis of rotation between a first extreme position at zero degrees, where the blade is parallel to the stock and partly provided in a space of the stock, and a second extreme position at about 270 degrees, where the blade is substantially perpendicular to the stock.

摘要： A stepwise and stepless adjustable square for use in carpentry, including: a stock; a blade; a first alignment structure; a second alignment structure; a spring device; a spring expansion-restricting element; and a knob movable between a first position and a second position, wherein in the first position the first and second alignment structures at certain angles between the stock and the blade align and engage such that a force of the spring device is reduced compared to the force at angles where the first and second alignment structures do not align for stepwise adjustment, and wherein in the second position the first alignment structure is moved axially away from the second alignment structure for stepless adjustment.
