The front and rear crank-rocker mechanisms are provided on the same eccentric drive shaft (3) for forming a jaw crusher with a single eccentric driving shaft, or the front and rear crank-rocker mechanisms are respectively connected to a front eccentric driving shaft (15) and a rear eccentric driving shaft (14) rotating synchronously by the driving wheel (2) for forming a jaw crusher with double eccentric driving shafts. The front and rear crank-rocker mechanisms are utilized for changing mechanical structure characteristics of the bottom of the swinging jaw and greatly improving functionality of the jaw crusher.
