Dozens or dozens of same carving devices are mostly arranged on one existing embroidery machine so as to increase the working efficiency of the embroidery machine. The plurality of embroidery machine engraving devices realize power transmission through a motor by a main shaft. Under the condition of the prior art, the up-and-down movement of the carving knife on the carving device is not high, and generally, 500 times per minute is required, so that the carving knife needs to be realized by a very excellent motor. The bottleneck of this technology is that a single motor drives so many engraving devices, and it is necessary to involve a very long transmission shaft, which drives all the engraving devices, so that the motor load is very large, and the torque for driving the transmission shaft to rotate is inversely proportional to the rotation speed, i.e. the higher the rotation speed, the smaller the torque, how to increase the rotation speed, and how to increase the torque to ensure sufficient driving force has been the subject of research by those skilled in the art. Certainly, the two ends of the transmission shaft are respectively connected with the motors, and the double motors achieve the technical effects of high rotating speed and large torque, but obviously, the technical effects are impossible, and the problem of shaft breakage caused by the fact that the two motors drive one transmission shaft simultaneously is inevitably caused under the condition of different torque rotating speeds.
