The invention provides a manual bolt processing device, which comprises a body, a saw cutter which is rotatably arranged at one side of a conveying belt body, a feed plate which is rotatably arranged on the conveying belt body and positioned at the bottom end of the conveying belt saw cutter and is provided with a clamp groove for placing bolts at the edge, and a cooling pipe which is arranged close to the conveying belt saw cutter, wherein a plane formed by the rotation advancing direction of the conveying belt saw cutter is vertical to the plane formed by the rotation advancing direction of the conveying belt feed plate; a guard plate corresponding to the edge of the conveying belt feed plate is also fixed at the side of the conveying belt feed plate; one end of the conveying belt guard plate is close to the conveying belt saw cutter; and a space only for placing bolts is reserved between the edges of the conveying belt saw cutter and the conveying belt feed plate. In the manual bolt processing device provided by the invention, the bolt can be fixed on the feed plate by arranging a corresponding guard plate on the edge of the feed plate, and the bolt is prevented from dropping due to the rotation of a common feed plate, thereby improving the grooving rate of the bolt.
