The invention discloses a push-up assembly tool for a magnetic force anastomat. The push-up assembly tool includes the magnetic force anastomat and an assembly mechanism thereof. The magnetic force anastomat includes a first body and a second body arranged opposite to each other, and the first body and the second body are provided with magnets attracting each other. The first body and the second body are provided with communicated through holes, and the assembly mechanism penetrates the through holes. The assembly mechanism includes an operating rod in clamped connection with the second body,an elastic clamping structure is arranged between the second body and the operating rod and includes a clamping portion and a clamping groove adaptive to the clamping portion, and the operating rod has a first state of causing the clamping portion to be embedded in the clamping groove and a second state of causing the clamping portion to be separated from the clamping groove to be separated from the second body and the operating rod. The push-up assembly tool has the advantages that a circular anastomat in a pin type anastomosis and a magnetic force anastomat in a magnetic force anastomosis are combined, and the advantages of the magnetic force anastomosis and the pin type anastomosis are synthesized.
