Abstract: The present invention provides a linkage swing head structure, including: a base, a drive mechanism and a spindle. The drive mechanism includes: a power mechanism, a connecting rod mechanism and a lead screw. An end of the spindle is fixed with a cutter, and the spindle is fixed on an end of the connecting rod mechanism. An end of the connecting rod mechanism fixed with the spindle is sleeved on a support bearing, the connecting rod mechanism can rotate around the support bearing, the support bearing is fixed on the base, and the other end of the connecting rod mechanism is movably connected to the lead screw. An output end of the power mechanism is connected to an end of the lead screw. The connecting rod mechanism adjusts the rotation angle of the spindle by sliding on the lead screw. The drive mechanism of the present invention is far away from the spindle, and the interference range thereof to the spindle is small.

Abstract: The present invention provides a multi-connecting rod linkage angle attachment head, including: a casing, a drive mechanism, and a spindle. The drive mechanism includes: a power mechanism, a connecting rod mechanism, and a fixing frame. 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.
