The displacement sensor 15 is an existing inductive displacement sensor, which obtains displacement information by measuring the inductance change between the metal sensor and the measured object. When the object approaches or moves away from the sensor, the inductance value of the metal sensor will change accordingly, and the displacement information of the object can be obtained by measuring the change of the inductance value. The electric telescopic rod 6 is the prior art. The working principle of the electric telescopic rod 6 is mainly based on motor drive and spiral combination transmission structure. In the electric telescopic rod, the motor is the core component, and it controls the extension and contraction of the telescopic rod by rotation. When the motor is started, the output shaft generates a rotational force, which is transmitted to the telescopic rod through the connector of the telescopic rod, thereby driving the extension and contraction of the telescopic rod. When the motor stops working, the telescopic rod will also stop extending and be fixed at the current length. The position of the drill rod 11 can be understood by rotating the plate 16.
