Abstract

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.

Description

technical field [0001] The invention relates to a riveting gun, which is used for easily taking out the rivet core stuck in the gun head during the riveting process. Background technique [0002] The riveting process of the rivet requires a riveting gun to pull the core. The general manual riveting gun includes two handles and a gun head with a built-in jaw seat; the front end of the handle is symmetrically hinged on both sides of the shell of the gun head, and the front of the handle and The hinged point of the gun head is provided with a movable connecting rod; the front end of the gun head is provided with a muzzle, the rivet core of the rivet is inserted into the muzzle, and the rear part of the gun head is provided with a puller, and the rod is hinged to the rear end of the puller , the front end of the puller is hinged to the outside of the rear end of the gripper seat in the gun head, and the puller is also connected to the inner side of the rear end of the gripper se...
