ABSTRACT:
A spring bar includes a spring, and two tubes are respectively connected to two ends of the spring. Each of the tubes has a slot, and a plurality of positioning recesses are defined in two insides defining the slot. Two mounting collars are respectively mounted to the two extensions on the two handles, and a through hole is defined through each of the mounting collars. Each of the two positioning members has a spring member which is biased in the mounting collar corresponding thereto and movably extends through the positioning hole and inserted in the slot. An annular groove is defined in each of the positioning members so that the handles can be pulled outward after the positioning members are pushed.
