A portable mortar mixer is provided to prevent a mixing screw from colliding with the inside of a mixing bucket and broken down by vibration by executing fixation without operators. An electric motor body(10) is composed of a gear installed in the end of a shaft of a downward motor; a first speed reduction gear engaged with the gear; a second speed reduction gear engaged with the first speed reduction gear in parallel; and a turning shaft extruded and protruded downward from the center of the second speed reduction gear. A fixing body(20) detachably fixes the electric motor body on the upside and has at least three support rod fixing units(21) at the lower side. Support rods(30) are combined with each support rod fixing unit and spaced from the floor at predetermined height. A shaft joint(40) is thread-joined to the end of the turning shaft of the electric motor body and composed of hinge combining units(41) moving inward and outward within a predetermined angle range and shaft combining screw units(42A,42B) formed at upper and lower ends. A mixing screw(50) is joined with the lower shaft combining screw unit of the shaft joint, moved inward and outward within the predetermined angle range, and composed of a rotary shaft(51) formed at the lower side and with the predetermined length and at least two wings(52) installed at the lower side of the rotary shaft. |
