1. An unmanned aerial vehicle (UAV) used in fishing, comprising:

  • a housing, said housing having a top part and a bottom part;

    a plurality of arms arranged on the top part, each arm having a motor and an airscrew;

    a battery unit arranged within the housing;

    a processor arranged within the housing;

    a sonar unit having a wire connected thereto; and

    a positioning unit detachably mounted within a mounting groove recessed from the bottom part,wherein the positioning unit is connected to the wire and configured to retract or release the wire,wherein the positioning unit comprises a rotator to engage the wire and a power component to actuate the rotator,wherein the positioning unit further comprises a supporting component to support the wire, and a first sensor to sense the force between the wire and the supporting component,wherein the first sensor comprises a first microswitch in contact with the supporting component,wherein the supporting component is hinged within the positioning unit,and wherein the processor is configured to instruct the power component to stop or decelerate in response to the first sensor sending a signal to the processor indicating the sensed force is less than a first predetermined threshold, in response to the first microswitch sending a signal to the processor indicating a displacement of the supporting component caused by a change in the force between the wire and the supporting component, and in response to the first microswitch switching off due to a rotation of the supporting component caused by a change in the force between the wire and the supporting component.
