Abstract

The positioning pin taking-out tool comprises a main rod, a baffle, a fixing ring and a connecting block, the fixing ring is fixedly installed outside the main rod, the baffle is arranged on the side, away from the fixing ring, of the side face of the main rod, the connecting block is installed at the bottom end of the main rod in a threaded mode, a fixing device is installed in the baffle, and a pulling device is installed outside the main rod in a sliding mode. Compared with a traditional positioning pin taking-out device, when the device is used, the main rod, the connecting block and the positioning pin can be rapidly and stably connected and fixed, the main rod can be conveniently pulled and impacted in the follow-up process, the sliding barrel continuously impacts the baffle due to the fact that the sliding barrel is continuously pulled, and the positioning pin can be taken out through the impact force. And the positioning pins are gradually pulled out, the parts are taken out and taken out, and the overall using effect is more perfect and efficient.
