[0020] The flexible shaft 5 is provided with a first output end 51 and a second output end 52, the first output end 51 is provided with a first blade 6, the first output end 51 passes through a first connecting hole and is fixedly connected to the first blade 6, the first blade 6 is rotatably connected to the first connecting hole, the second output end 52 is provided with a second blade 7, the second output end 52 passes through a second connecting hole and is fixedly connected to the second blade 7, the second blade 7 is rotatably connected to the second connecting hole.

[0021] Specifically, the driving mechanism drives the output gear 1 to rotate, the No. 1 bearing 2 is sleeved on the connecting end of the output gear 1 and fixedly connected to the gear box 10, and the output gear 1 is positioned axially and radially, the output gear 1 is meshed with the transmission gear 3, the output gear 1 drives the transmission gear 3 to rotate, the transmission gear 3 is fixedly connected to the flexible shaft 5 through a flat key 31, the No. 2 bearing 4 is sleeved on the flexible shaft 5 and fixedly connected to the gear box 10, and the position of the flexible shaft 5 and the transmission gear 3 is fixed, the transmission gear 3 drives the flexible shaft 5 to rotate, the first output end 51 and the second output end 52 of the flexible shaft 5 respectively drive the first blade 6 and the second blade 7 to rotate, the first blade 6 and the second blade 7 rotate to cooperate to perform operations such as loosening the soil.

[0022] In the above structure, the flexible shaft 5 is respectively connected to the first cutter head and the second cutter head, so that the driving mechanism drives the output gear 1 to drive the transmission gear 3 to rotate. When the transmission gear 3 drives the flexible shaft 5 to rotate, the flexible shaft 5 can drive the two cutter heads to rotate simultaneously and in the same direction, thereby reducing the friction between the two cutter heads. The device not only reduces the wear between the two cutter heads, but also increases the service life of the cutter heads and reduces the replacement cost. The flexible shaft 5 is used to drive the two cutter heads to rotate. This setting not only reduces the operating cost, but also facilitates the adjustment of the loosening angle between the two cutter heads.

[0023] like Figure 1 As shown, in one embodiment, the angle between the first blade 6 and the second blade 7 of the flexible shaft dual-output tiller is 60 degrees.
