Adjusting device for wire passing wheel of wire cutting machine

The invention provides an adjusting device for a wire passing wheel of a wire cutting machine. The adjusting device comprises a long-bar-shaped sliding rail which is transversely arranged, a transverse moving sliding block and a fastening mechanism. The transverse moving sliding block is arranged on the long-bar-shaped sliding rail in a sleeving manner and can slide along the long-bar-shaped sliding rail. A threaded hole is formed in one side of the transverse moving sliding block, and the transverse moving sliding block is used for driving the wire passing wheel to move along the long-bar-shaped sliding rail. The fastening mechanism comprises a bolt and a pressing block, the pressing block is provided with a clamping groove matched with the outer side surface of the long-bar-shaped sliding rail, the bolt is screwed in the threaded hole of the transverse moving sliding block, one end of the bolt penetrates out of the transverse moving sliding block and is connected with the pressing block so that the pressing
