Pin bottom bending device

The invention relates to a pin bottom bending device which is provided with a supporting structure, a first working claw and a second working claw, and the first working claw and the second working claw are assembled together in a paired mode and are supported on the supporting structure through a guiding system for guiding the first working claw and the second working claw to be relatively close to or away from each other. The first working claw and the second working claw are guided by the guide system to reciprocate along the X axis of a space coordinate; and the driving assembly is assembled on the supporting structure to synchronously drive the first working claw and the second working claw to move relatively, so that an opening state or a closing state between the first working claw and the second working claw is established. According to the pin bending device, pin bending work is met, the working claws move in parallel to be opened and closed, Z-direction parameters do not need to be changed during pi
