The invention discloses a hand riveter capable of throwing away rivet cores. The hand riveter is used for easily taking out the rivet cores in a riveter head in the riveting process. The hand riveter comprises handles, supporting rods and the riveter head, pull sleeves connected with clamping jaw seats are arranged on the rear portion of the riveter head, through holes are formed in the middles of the rear ends of the pull sleeves, the rear ends of the pull sleeves are connected with a piston sleeve pipe, and a piston rod is arranged in the piston sleeve pipe. The front end of the piston rod penetrates through the through holes in the rear ends of the pull sleeves and then enters the space between the two clamping jaw seats. The end, connected with the pull sleeves, of the piston sleeve pipe is open, and the other end of the piston sleeve pipe is closed. A cylindrical piston rod cap is arranged at one end of the piston rod, and a piston rod pin thinner than the piston rod cap is arranged at the other end of the piston rod. The piston rod cap faces the sealed side of the piston sleeve pipe, and the piston rod pin stretches to the position, between the two clamping claw seats, in the riveter head. If the rivet cores are adhered to multi-tooth clamping jaws in the riveting operation process and clamped in the riveter head, an operator holds the handles and swings the riveter head, the piston rod pin slides into the riveter head, and the rivet cores adhered to the multi-tooth clamping jaws can be jacked out.
