ABSTRACT:
A handle of a push cart includes two rods slidably engaged in two tubes and each having a number of teeth. Two sleeves are secured on top of the tubes and each has a pair of lugs. Two pins are secured between the lugs. A resilient arm has two ends slidably engaged with the pins, the ends each includes a tooth for engaging with the teeth of the rods so as to secure the rods to the tubes. The teeth of the resilient arm are disengaged from the teeth of the rods when the resilient arm is depressed. A fence is secured to the sleeves for preventing the resilient arm from being depressed inadvertently.
