A portable strapping apparatus has a semi-automatic fastening mechanism that uses a transmission unit in conjunction with a unidirectional bearing to drive a tensioning wheel. The tensioning wheel is provided with two slots arranged in a mutually perpendicular manner or a plurality of slots, by which the tensioning wheel can achieve a better binding strength. For facilitating the welder to push two strapping bands to positively abut against each other, an elastic presser located on one side of the tensioning wheel is used to gradually release strapping bands before welding. Thus the strapping apparatus according to the invention can positively perform the welding and cutting of strapping bands to effectively bind articles.
