Abstract
A knuckle assembly includes two mirror-symmetric knuckle ends that are separately connected to two adjacent ends of two long members so that the two long members may be angularly connected together in a bent or an extended position as desired. The two knuckle ends are provided with two fastening pins, one of which may be easily pushed to lock the two knuckle ends in the angularly extended position and the other of which may be easily pushed to unlock the two knuckle ends from the angularly extended position so that the two knuckle ends may be bent relative to each other to occupy only a reduced space.
