1. A gardening tool, comprising:

  • a main body having at least a functional accessory and a motor for driving the functional accessory;

    a handle, rotatably connected to the main body, having at least one operation assembly for being operated by a user to control the motor when the handle is in a secure position wherein the operation assembly is capable of sliding relative to the main body; and

    a control system for sending a control signal to prevent the motor from being controlled by the operation assembly and halting the motor when the handle is out of the secure position, the control system comprising;

    a first control device configured to be controlled by the operation assembly;

    a second control device configured to be controlled according to the rotating position of the handle wherein, when the handle rotates to a designated rotating position relative to the main body, the second control device unlocks the first control device so that the first control device allows starting of the motor, and, when the handle rotates to a position other than the designated rotating position relative to the main body, the second control device locks the first device so that the first control device is not allowed to start the motor; and

    a third control device configured to be controlled according to the sliding position of the operation assembly relative to the main body wherein, when the operation assembly slides to a designated sliding position, the third control device unlocks the first control device so that the first control device allows starting of the motor, and, when the operation assembly slides to a position other than the designated sliding position relative to the main body, the third control device locks the first device so that the first control device is not allowed to start the motor.
