Meanwhile, the driving mechanism 300 is used for driving the turnover mechanism 200 to rotate around the central axis of the turnover mechanism 200, so as to drive the wire clamping pliers 20 to rotate. Further, the driving mechanism is further configured to drive the turnover mechanism 200 to drive the wire clamping pliers 20 to move from a preset initial position to a preset end position along a preset route, where the preset initial position of the wire clamping pliers 20 and the preset end position of the wire clamping pliers 20 are spaced apart from each other along a second direction of the automatic wire turning device 1000, and when the wire clamping pliers 20 move along the preset route, the driving mechanism 300 may drive the turnover mechanism 200 to move in a first direction (i.e. an up-down direction in fig. 3) of the automatic wire turning device 1000, so as to prevent the wire clamping pliers 20 from collision and interference with the clamping mechanism 100 in the wire turning process as much as possible, and prevent the wire clamping pliers 20 and the clamping mechanism 100 from collision and damage as much as possible.

When the first driving member 37 is extended and the length dimension is increased, the first driving member 37 drives the second moving seat 33 to move away from the first driving member 37 through the transmission rod 38.
