A jaw crusher includes a machine with a moving base, a fixed base, a crush travel adjusting mechanism for pivotally coupling the top of a crush travel adjusting base to the machine by an eccentric sleeve, and an automatic crush gap adjusting mechanism. A toggle plate is installed between the crush travel adjusting base and the moving base. A pull rod of the moving base having a compression spring tightly presses front and rear ends of the toggle plate. The automatic crush gap adjusting mechanism fixes a steel slot of a stop plate and a pair of triangular wedge-shaped lumps to the position adjusting base of the machine, and the stop plate is installed between the steel slot and the crush travel adjusting base, and a pull rod of the adjusting base having a compression spring tightly presses both front and rear ends of the stop plate.
