[0031] ​The front end wire length detection mechanism of the movable long guide 11 receives the steel wire delivered by the lifting auxiliary structure fork arm 09 which is nested in the structure of the horizontal moving main fork arm 08.

[0032] The hydraulic system integrated in the structure of the horizontal moving main fork arm 08 serves as the power source for the lifting of the lifting auxiliary structure fork arm 09. After the lifting auxiliary structure fork arm 09 is lowered, it completes the conveying and shearing of the steel wire for grabbing.

[0044] The movable length guide 11 is used for receiving the steel wire delivered by the steel wire delivery mechanism 03 and the steel wire hydraulic straightening roller 02, and has a length detection mechanism at the front end, which is adjusted symmetrically with the center line of the main shaft according to the position of the steel wire cutting knife to ensure that the delivered steel wire can completely wrap the baled object according to the preset center symmetry.
