[0005] Preferably, the oar connecting bracket is composed of a lower rod, a threaded groove, a screw rod and an upper rod.

[0006] Preferably, the upper rod in the oar connection bracket is connected to the universal shaft.

[0007] Preferably, position sensors are fixedly connected to the left and right ends of the power transmission mechanism bracket.

[0008] Preferably, the two groups of position sensors are located at two ends of the swing area of ​​the swing rod.

[0009] The present invention has the following advantages: The present invention provides a hand-cranked boat oar motion mechanism through improvement, which has the following improvements compared with the same type of equipment:

[0010] The hand-cranked oar movement mechanism described in the present invention can start the motor to indirectly drive the outer edge fixed inner arc bearing to apply thrust to the oar, so that the oar swings left and right, realizes the simulation of human rowing and pushes the boat to move. The use of motor drive can significantly improve the efficiency of rowing, because the motor can continuously and stably output power without being affected by fatigue and physical limitations like human power. This not only saves a lot of manpower, but also enables the boat to maintain a faster speed and a longer range. Through the motor and gear transmission system, the swing amplitude and frequency of the oar can be accurately controlled, making the boat's navigation more stable. At the same time, this mechanical transmission method also reduces the uncertainty and error of human operation, making the boat's navigation more reliable and predictable.

[0011] The hand-cranked boat oar movement mechanism described in the present invention can move the upper rod to adjust the height position, and then adjust the height of the boat oar connection bracket according to the above method, and drive the universal shaft to adjust the height to match the outer edge fixed inner arc bearing. The combined effect enables the boat oar to be adjusted in different ranges, different heights and different movement speeds. The mechanical structure is highly universal for different boat oars and different water depths, greatly increasing the application scope and scenarios of the structure.
