Abstract
Abstract In a portable type machine, material supporting members adapted to be stretched for use during the use of the machine are pivotally connected to the opposite sides of the machine for upward rotation and during the transportation of the machine, the supporting members are pivoted onto the top of the machine body so as to form a transportation handle on top of the machine body. By one touch, the machine can be transformed from its shape during use into a compact shape suitable for transportation, thus greatly enhancing the transportation efficiency of the machine.
