A clutch unit capable of changing torque is provided between transmission shaft three and transmission shaft two.

2. The outboard low-speed intermittent drive clutch system according to claim 1, characterized by The gearbox also has a mating cavity that communicates with the control cavity. The mating cavity is located at the upper end of the control cavity, and the inner wall of the side of the mating cavity has a mating hole that extends outward. The clutch unit includes driven gear 1 and driven gear 2, which are coaxially and fixedly arranged with transmission shaft 2, and driving gear 1 and driving gear 2, which are slidably arranged with transmission shaft 3. Driving gear 1 is used to engage with driven gear 1, and driving gear 2 is used to engage with driven gear 2. Driving gear 1 and driving gear 2 are fixed to each other. When driving gear 1 and driving gear 2 reciprocate, they can respectively engage driven gear 1 and driven gear 2 with driving gear 1 and driving gear 2.

3. The outboard low-speed intermittent drive clutch system according to claim 2, characterized by The clutch unit also includes a control unit for controlling the reciprocating movement of the first drive gear and the second drive gear. The control unit includes a clamping block that slides in the mating cavity, and a clamping fixture fixed at the lower end of the clamping block for clamping the outer sides of the first drive gear and the second drive gear. A threaded shaft extending outward from the mating hole is fixed on the outer side of the clamping block. A nut is threadedly connected to the outer end of the threaded shaft. The nut is used to control the movement of the threaded shaft. A limit buckle is fixed on the outer side of the gearbox. The limit buckle is used to clamp the nut between the limit buckle and the gearbox. The limit buckle is provided with a hole for the threaded shaft to pass through.

4. The outboard low speed intermittent drive clutch system of claim 3 wherein, A sealing ring is provided on the side of the nut that contacts the gearbox to seal the gap between the mating hole and the threaded shaft.

5. The outboard low speed intermittent drive clutch system of claim 3 wherein, The inner wall of one side of the mating cavity is also provided with an outward-through oil injection hole, and the oil injection hole is plugged with a rubber plug to seal the oil injection hole.

6. The outboard low speed intermittent drive clutch system of claim 3 wherein, A groove is provided on the outer ring surface of the transmission shaft three near one end. The inner ring surfaces of the drive gear one and drive gear two are embedded in the groove to enable the drive gear one and drive gear two to rotate synchronously with the transmission shaft three.

7. The outboard low speed intermittent drive clutch system of claim 3 wherein, A connecting sleeve is fixed between driven gear one and driven gear two. The connecting sleeve is used to control the distance between driven gear one and driven gear two. When the clamping block is in contact with the inner walls on both sides of the mating cavity, it can make driving gear one mesh with driven gear one or driving gear two mesh with driven gear two respectively.

8. The outboard low speed intermittent drive clutch system of claim 7 wherein, The thicknesses of drive gear 1, drive gear 2, driven gear 1, and driven gear 2 are all the same, and the length of the connecting sleeve is greater than the thicknesses of drive gear 1, drive gear 2, driven gear 1, and driven gear 2.

9. The clutch system for intermittent drive of an outboard motor in low-speed driving state according to claim 7, characterized in that, The diameter of the first driving gear is smaller than that of the second driving gear, while the diameter of the first driven gear is larger than that of the second driven gear.

10. The outboard low speed intermittent drive clutch system of claim 1 wherein, One end of the transmission shaft extends outward to form a gearbox, and the outer ring of the extended end is fixed with a propeller blade for driving the ship's movement.
