1. A multi-connecting rod linkage angle attachment head, comprising: a casing; a drive mechanism; and a spindle with a cutter fixed at an end, wherein:
the drive mechanism includes: a power mechanism, a connecting rod mechanism and a fixing frame for supporting the power mechanism; the fixing frame is fixedly connected to an inner wall of the casing, and the power mechanism is fixedly connected to the fixing frame;
the connecting rod mechanism includes: a first connecting rod, a second connecting rod and a third connecting rod; an end of the first connecting rod is rotatably connected to the fixing frame, and is fixedly connected to an output end of the power mechanism, the other end of the first connecting rod is rotatably connected to an end of the third connecting rod via a first pin, the other end of the third connecting rod is rotatably connected to an end of the second connecting rod via a second pin, the other end of the second connecting rod is fixed on a side wall of the spindle; the second connecting rod and the spindle are rotatably connected to a support bearing fixed in the casing;
the rotation axis of the power mechanism is parallel to the horizontal plane, the rotation axes of the first connecting rod, the second connecting rod and the third connecting rod are all parallel to the rotation axis of the power mechanism; the power mechanism is located above the spindle; and
an end of the third connecting rod close to the support bearing is a bent portion for preventing interference with the support bearing.
