A container mixing stand for securing a container for mixing includes a base plate, a first holding member connected to the base plate and a second holding member movably connected to the base plate and spaced from the first holding member for receiving a container between the first and second holding members. The stand also includes a first pulley assembly having a lever arm movable between a rest position and a tensioning position, and a second pulley assembly coupled with both the second holding member and the first pulley assembly. Movement of the first pulley assembly from the rest position to the tensioning position causes the second pulley assembly to move the second holding member into contact with the container for securing the container in position during mixing.
