The invention discloses a swirl burner with a variable cone expanding angle. The swirl burner comprises an air bellow, a secondary air chamber, a primary air pipe, a central air duct and a plurality of swirl vanes. A front group of secondary air expansion cones and a rear group of secondary air expansion cones which are axially arranged front and back are arranged outside the primary air pipe, the two groups of secondary air expansion cones comprise a plurality of front expansion cone blades or rear expansion cone blades which are arranged along the outer circle of the primary air pipe at intervals, and the root of each expansion cone blade is connected with the primary air pipe through a rotating shaft. Each cone expanding blade is connected with one end of the corresponding pull rod behind, and the other end of each group of pull rods is connected with the corresponding pull ring; the front cone expanding blades and the rear cone expanding blades are arranged in a staggered manner in the circumferential dir
