Working principle: When the device is used, the rectangular block at the lower end of the telescopic rod is inserted into the rectangular groove at the top of the mounting block, and the rectangular block is fixed inside the rectangular groove by the limit assembly. Then the length of the telescopic rod is adjusted to match the height of the user, and the device can be used normally. (The fixed box and the trenching knife are placed at the position where trenching is required, and the drive motor is turned on. The drive motor drives the rotation of the transmission gear through the rotating shaft, thereby driving the reduction gear and the top synchronous wheel to reduce the rotation, thereby driving the rotation of the synchronous belt and the bottom rotating shaft. The rotation of the bottom rotating shaft drives the rotation of the drive wheel. The surface of the drive wheel contacts the ground through the rotating paddle, thereby assisting the movement of the fixed box and assisting the trenching operation of the trenching knife).
