The movement driving mechanism 50 may be a motor-driven sliding module structure.

As shown in fig. 2, the device further includes a detection switch 60, where the detection switch 60 is disposed at a side of the second clamping member 10 to detect a rotation angle of the second clamping member 10.

It will be appreciated that. When the first stopper 302 on the mounting plate 303 follows the rotation of the turntable 301 to the detection range of the detection switch 60, the driving member of the turntable 301 is caused to reversely drive the rotation of the mounting plate 303, thereby causing the expansion pipe 20 and the second clamping member 10 to rotate back and forth, so as to facilitate the loosening treatment and expansion of the shielding net.

As will be appreciated, since the end of the wire held by the first holding member is in a suspended state, the wire can be held close to the first holding member by the auxiliary holding jaw 70 and kept in the held state to be moved close to the end of the wire, whereby the suspended length of the wire can be straightened, facilitating the handling of the wire by loosening and expanding the wire by being on the same horizontal line as the second holding member 10.

With respect to the auxiliary jaw 70, the auxiliary jaw 70 includes an auxiliary jaw 701, a grip driving member 702, and a moving driving member 703, the grip driving member 702 being connected to the auxiliary jaw 701, the moving driving member 703 being connected to the grip driving member 702 to drive the grip driving member 702 to move between a first position near the first clamping member and a second position near the second clamping member 10, thereby driving the auxiliary jaw 701 to clamp the electric wire near the first clamping member and to move the clamped state to near one end of the shielding net, whereby the suspended length portion of the electric wire can be straightened, facilitating the treatment of loosening and expanding of the shielding net while the shielding net is on the same level as the second clamping member 10. Wherein, the clamping driving member 702 may be a cylinder mechanism, and the moving driving member 703 may be a cylinder driving moving pair structure.
