The positioning block 6 is installed on the square adjusting rod 45 by bolt connection.

[0030] The process of the follower frame 5 following the movement of the wire rod is as follows: After one end of the wire rod abuts against the positioning block 6, the positioning block 6 can drive the square adjusting rod 45 and the moving frame 40 to move. The moving direction of the moving frame 40 can be ensured through the guide cylinder 41 and the guide rod 42. When the moving frame 40 moves, the return spring 44 can be compressed. During the cutting process, when the cut part of the wire rod abuts against the cutting part of the cutter 7, it can also cause the cutter 7, the follower frame 5, and the positioning block 6 to continue to move backward. After the cutter 7 cuts the wire rod and returns, that is, when the cutting part of the cutter 7 is separated from the wire rod, at this time, the wire rod can pass through between the cutters 7, and then under the elastic force of the return spring 44, the moving frame 40 can be pushed back to its original position.

[0031] Refer to the attached drawings of the specification Figure 1 , the attached drawings of the specification Figure 5 , the attached drawings of the specification Figure 6 , the attached drawings of the specification Figure 9 and the attached drawings of the specification Figure 11 , the positioning block 6 includes a square moving block 46.

Under normal conditions, the blanking spring 53 is in a compressed state. The blanking spring 53 can push one end of the T-shaped rotating block 52 downward and make the other end of the T-shaped rotating block 52 move upward. When the other end of the T-shaped rotating block 52 abuts on the limit rod 54, the rotation can stop. Place one end of the wire rod against the lower end of the T-shaped rotating block 52. When the wire rod is cut off, the end of the wire rod close to the cutter 7 can move downward, and the end of the wire rod close to the T-shaped rotating block 52 can rotate upward, and then the blanking spring 53 can be compressed, which will cause the wire rod to be placed obliquely, and then the wire rod can fall.
