     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      As shown in  FIGS. 1 and 2 , the present invention comprises a wheel strut  1  and a handle tube  2 . The wheel strut  1  is inserted into the handle tube  2 .  
      The wheel strut  1  has a block  11  protruding from a lower section thereof. The handle tube  2  is provided with a sleeve  21 . The sleeve  21  has an arcuate trough  211  and the handle tube  2  has an arcuate recess  22  for the block  11  to slide therein.  
      When turning the handle towards either direction, the block  11  of the wheel strut  1  will slide along and within the arcuate recess  22  of the handle tube  2  and the arcuate trough  211  of the sleeve  21 . Upon the block  11  reaches to the end of the arcuate trough  211 , the turning movement will be stopped thereat so that the handle is confined to turn within a pre-determined range to keep the cart in a safety status.
