Adjustable knockdown tool

An adjustable knockdown tool comprising:

• a coupling member including a housing, the housing defining a channel extending through the housing between a first channel aperture defined at the housing and a second channel aperture defined at the housing, the housing further including an actuator receptacle and a locking element, the locking element located between the actuator receptacle and the channel, the locking element being movable between a locking position at which the locking element extends into the channel and a releasing position at which the locking element retracts away from the channel toward the actuator receptacle;
• a blade support extending through the channel, the blade support coupled to a blade member that extends out from the blade support, the blade support being rotatable relative to the channel when the locking element is at the releasing position so as to change an angle of the blade member relative to the housing, and the blade support being fixed relative to the channel when the locking element is at the locking position so as to fix the angle of the blade member relative to the housing;
• and
• an actuator configured to be coupled to the actuator receptacle, wherein coupling the actuator to the actuator receptacle causes the locking element to move from the releasing position to the locking position so as to fix the angle of the blade member relative to the housing.
