How to disconnect connecting rod and crank

  1. Feb 23, 2013 #1
    I have a mechanism
    wish to disconnect connecting rod and crank when i cycling so that i do nt need to use additional force to turn connecting rod also
    but connect them once my driving system is set up and piston that connected to rod can rotate my crank
    how can i set up this mechanism?
