When the driving state is entered, two persons can drive the pleasure boat; when the ship enters the separation state, the ship can only be driven by a single person. The transmission state in the present embodiment means that transmission can be performed between the transmission mechanism 10 and the screw driving mechanism 8, and the separation state means that transmission cannot be performed between the transmission mechanism 10 and the screw driving mechanism 8.
As shown in fig. 6 to 11, the clutch unit includes a clutch assembly 14 and a control assembly, the clutch assembly 14 includes a mount 20 slidably fitted in the frame 4 and a spline housing 21 rotatably fitted on the mount 20 through a bearing 24, the spline housing 21 being rotatable on the mount 20 while an initial position of the spline housing 21 is located on the output spline shaft 17, but the spline housing 21 is slidable from the output spline shaft 17 to the input spline shaft 16 and is capable of spline-coupling with both the input spline shaft 16 and the output spline shaft 17.
The control assembly comprises a linear drive member and a clutch limiter 15 mounted on the frame 4, the linear drive member being connected to the mount 20 to drive the mount 20 and spline housing 21 to slide over the input spline shaft 16 and the output spline shaft 17 to shift the transmission mechanism 10 and the screw drive mechanism 8 between a transmission state and a disengaged state. The clutch limiter 15 can be in a stop fit with the mount 20 in the axial direction of the input spline shaft 16 to limit movement of the mount 20. When the transmission mechanism 10 and the screw driving mechanism 8 are in a transmission state, the clutch limiting piece 15 limits the mounting seat 20 and the spline sleeve 21 on the input spline shaft 16 and the output spline shaft 17; when the transmission mechanism 10 and the screw driving mechanism 8 are in a separated state, the clutch limiter 15 limits the mounting seat 20 and the spline housing 21 to the output spline shaft 17.
By arranging the clutch unit, the mounting seat 20 and the spline housing 21 in the clutch unit slide back and forth on the input spline shaft 16 and the output spline shaft 17, so that the transmission mechanism 10 and the screw driving mechanism 8 are changed between a transmission state and a separation state, when two persons are required to drive the pleasure-boat main body to move together, the transmission state can be changed, when two persons are not required to drive the pleasure-boat main body to move, the corresponding transmission mechanism 10 and the screw driving mechanism 8 can be changed into the separation state, the load of single person driving is reduced, and labor is saved; the linear driving member can drive the mounting seat 20 to move, so that the transmission mechanism 10 and the screw driving mechanism 8 are kept in a transmission state or a separation state.
The linear driving member in this embodiment includes two pull rods 11 fixedly assembled on two sides of the mounting base 20, sliding holes 52 are formed on two sides of the frame 4, each pull rod 11 extends out of the frame 4 through the corresponding sliding hole 52, the pull rod 11 can move in the corresponding sliding hole 52 to push the mounting base 20 and the spline housing 21 to move, and a user can move the mounting base 20 and the spline housing 21 through the pull rod 11 in the outside.
In other embodiments, the linear drive is an electric push rod or a pneumatic or hydraulic cylinder, for example, the electric push rod is mounted on the frame 4, the electric push rod is connected to the mount 20, and the electric push rod drives the mount 20 and the spline housing 21 to move on the input spline shaft 16 and the output spline shaft 17.

A spring 18 is provided between the pushing end 12 and the frame 4, the spring 18 is used for maintaining the clutch limiter 15 in a state perpendicular to the axial direction of the output spline shaft 17, if the pushing end 12 rotates in the direction of the output spline shaft 17, the spring 18 generates a pulling force on the pushing end 12, and if the pushing end 12 rotates in the direction of the input spline shaft 16, the spring 18 generates a pushing force on the pushing end 12.
The spring 18 maintains the clutch limiter 15 in a state perpendicular to the axial direction of the output spline shaft 17, and simultaneously enables the limiting end 23 and the limiting groove 22 to continuously perform stop fit so as to limit the movement of the mounting seat 20 and the spline housing 21 on the output spline shaft 17, so that the transmission mechanism 10 and the screw driving mechanism 8 are in a separated state.
The user pushes the pushing end 12 to enable the pushing end 12 to rotate towards the direction of the output spline shaft 17, the limiting end 23 is separated from the limiting groove 22, the user pulls the pull rod 11 to drive the mounting seat 20 and the spline sleeve 21 to move from the output spline shaft 17 to the input spline shaft 16, at the moment, the mounting seat 20 and the spline sleeve 21 are simultaneously in spline connection with the input spline shaft 16 and the output spline shaft 17, so that the transmission mechanism 10 and the screw driving mechanism 8 are in a transmission state, at the moment, because the user does not push the pushing end 12 any more, the limiting end 23 can rotate towards the direction of the output spline shaft 17 due to the pulling force of the spring 18, in the rotating process, the limiting end 23 can be propped against the mounting seat 20, at the moment, the spring 18 pulls the pushing end 12, so that the limiting end 23 still has the tendency to rotate towards the direction of the output spline shaft 17, but because of the limitation of the mounting seat 20, the limiting end 23 is not in the past, and at the same time, the movement of the mounting seat 20 and the spline sleeve 21 towards the direction of the output spline shaft 17 is limited, so that the transmission mechanism 10 and the screw driving mechanism 8 can continuously be in the transmission state.
