[0043] Through the above scheme of the present invention, a small saw blade with a width of 0.5-1.8mm milling manufacturing process has the following operating procedures during use: both ends of a saw blade are placed flat in the groove wheel and driven by the groove wheel mechanism at the length center of the saw blade. The groove wheel is 6. The groove can rotate 60° by manually turning the active lever. The saw blade in the first groove enters the preparation position, and then the second groove enters the saw blade placement position, and the second blade can be placed. After shaking the active rod twice, the first saw blade enters the upper pin position and has rotated 120° from horizontal to vertical. A 2.2mm long steel wire is exposed in front of the saw blade plane. There is a cylinder at the back that moves forward in the groove against the saw blade. The steel wire hits the saw blade and enters the saw blade under the action of force. The cylinder returns and enters the front end of the saw blade. The steel wire is exposed 2mm, but the back must also be 2mm long. In this way, the steel wires on both sides of the saw blade are the same length, so the steel wire is cut at 2mm in the mold, and the long steel wire at the back is pushed forward 4.2mm, exposing 2.2mm from the mold to prepare for the next one. In this way, the saw blade with the upper pin is pushed back into the groove. The active rod is rotated again, and the saw blade with the upper pin is turned to the bottom and falls freely. One is added on the top and one is dropped on the bottom (see Figure 4 ).
