Abstract
The invention relates to a pin puller. The pin puller comprises a rotating rod, a pin pulling head and a connecting sleeve. The rotating rod comprises a rotary rod and a handheld part. The handheld part is arranged at one end of the rotary rod. One end of the pin pulling head is detachably connected to the end, far from the handheld part, of the rotary rod. The other end of the pin pulling head is provided with a threaded part used for being matched with a taper pin in a machine tool. The connecting sleeve is connected to the end, far from the rotating rod, of the pin pulling head. The pin pulling head is screwed onto the taper pin through the threaded part, the connecting sleeve abuts against the machine tool, and the rotating rod rotates to drive the taper pin to be screwed out of the machine tool. According to the pin puller, after the pin pulling head on the pin puller is in screw-thread fit with the taper pin, an operator can screw the pin pulling head out of the machine tool slowly by rotating the rotating rod; compared with the traditional mode that the taper pin is pulled out through impact force, the pin puller will not injure the hand of the operator because of maloperation and other causes, and personal safety of the operator is effectively protected.
