Outboard motors can realize the forward, turning and backward movements of boats. They have the characteristics of compact structure, light weight, easy loading and unloading, simple operation, and low noise. They are suitable for use in inland rivers, lakes and offshore.

[0024] As an implementation method in this embodiment, Fig.13 , Figure 21 to Figure 23As shown, the actuator 110 also includes a connecting member 130, which includes a rotating shaft 131.

At this time, the transmission shaft C172 drives the grooved gear column 142 to rotate, so that the grooved gear column 142 is meshed with the inner gear ring 149, thereby driving the inner gear ring 149 to mesh with the hollow gear column 140, so that the rotation speed of the hollow gear column 140 and the grooved gear column 142 is the same, and at the same time, the hollow gear column 140 drives the rotating shaft 131 to rotate.

[0027] As an implementation method in this embodiment, Figure 2 and Figure 6 As shown, the bottom of the hook shell 200 is fixedly connected to the top of the propeller shell 100 by bolts, and a top shell 210 is fixedly installed on the top of the hook shell 200.

[0029] When a boat moves in a river channel covered with weeds and tendon-like aquatic plants, the underwater part of the outboard motor is easily hooked by the very tough aquatic plants and blocked, making the boat unable to move forward. At this time, the gear on the side wall of the outboard motor housing 200 drives the transmission rod 145 to rotate, so that the sub-gear 144 and the gear rod 146 are meshed, thereby driving the gear rod 146 to move forward, and then pushing the push ring 147 and the inner gear ring 149 forward, so that the inner gear ring 149 is meshed with the hollow tooth column 140, the convex gear ring 141, and the grooved tooth column 142. At this time, the transmission shaft C172 drives the grooved tooth column 142 to rotate, so that the grooved tooth column 142 is meshed with the inner gear ring 149, thereby driving the inner gear ring 149 to mesh with the hollow tooth column 140, so that the rotation speed of the hollow tooth column 140 and the grooved tooth column 142 is the same, and at the same time, the hollow tooth column 140 drives the rotating shaft 131 to rotate, so that the helical gear on the rotating shaft 131 The gear 135 on the driven shaft 133 is meshed with the main gear 136 on the driving shaft 134, thereby driving the driving shaft 134 to rotate. At this time, the driving shaft 134 can drive the eccentric block 127 at the bottom to rotate, so that the eccentric block 127 drives the top of the bridge-type pendulum 126 to rotate. When the bridge-type pendulum 126 moves to the left side of the eccentric block 127, the left side of the double pendulum frame 121 will swing downward. Similarly, when the bridge-type pendulum 126 moves to the right side of the eccentric block 127, the right side of the double pendulum frame 121 will swing downward, so that the two groups of push cylinders 125 can reciprocate in the strip limit plate 117, and the movement directions are always opposite. At this time, the saw blade 114 fixedly connected to the push cylinder 125 through the Z-shaped saw handle 116 can perform high-frequency and small-distance reciprocating motion in the square cutting shell 113, thereby efficiently cutting aquatic plants.
