A deadlocked strap releasing device for a strapping machine, provided in a machine body wherein a strap is guided by a strap moving device into a guide base and onto a guide rail to be extended to be laid on an object to be strapped on a worktable, and said deadlocked strap releasing device is positioned below said guide rail to release the strap if deadlocked, said deadlocked strap releasing device comprising:

a strap ejector having a pivot sleeve located at a side where a strap is guided out of a guider, a horizontal plate of a proper length resting on and extending from said pivot sleeve forward, a hook rod of a preset length fixed under said horizontal plate, an L-shaped push member extending up from the front side of said horizontal plate and located a little below a guide rail, and an actuating member extending downward from said horizontal plate;
a spring having one end hooking said hook rod and the other end hooking a position rod provided below said hook rod, supplying said strap ejector with resilience to move up for ejecting said strap up and let said horizontal plate rest on a stop rod provided in a machine body;
a pull rope having a proper length, one end connected with a ring-shaped head fixed with a lower end of said actuating member, the other end formed as a tail passing through a rope guider and a fixing base and protruding out of said fixing base fixed on a side plate of said machine body, said rope guider fixed at a location between said fixing base and said strap ejector;
a guide tube fixed with said side plate of said machine body, located a little above said fixing base, having an inner portion located inside said machine body and an outer portion outside said machine body, and a center guide hole;
and,
a pull rod pivotally fitting in said guide tube, having an inner portion located in said machine body and fixed with said tail of said pull rope and an outer portion located outside said machine body and connected with a knob at its outer end.
