Impact type chip breaking device

An impact type chip breaking device is fixedly installed on a cutter handle, a cutting blade is arranged at one end of the cutter handle and comprises a fixing piece, a rotating idler wheel, an eccentric driving mechanism and a chip breaking impact block, one end of the fixing piece is fixedly arranged on the cutter handle, and the other end of the fixing piece extends towards the direction of thecutting blade and is fixedly connected with the center of the rotating idler wheel through a pin shaft. The rotating roller is tangent to the workpiece, the chip breaking collision block is arrangedabove the cutting blade, the eccentric driving mechanism is fixedly arranged on the pin shaft, and one end of the eccentric driving mechanism is fixedly connected with the chip breaking collision block and drives the chip breaking collision block to periodically impact the root of the chip of the workpiece. According to the chip breaking device, the chips are broken into small chips with certain lengths by periodically imp
