New description: [New technology field] This creation is about an electric telescopic rod, especially an electric telescopic rod that can stop the movement of the telescopic rod accurately. [Prior Art] There are many known devices or mechanisms that require a linear motion to provide the power of the S, such a linear reciprocating drive, 4 see the hydraulic pressure of the hydraulic Cylinder, Qianche electric motor driven screw cup mechanism. The use of the new force pressure cylinder also requires the construction of the miscellaneous pipeline and the control valve. (4) The liquid island system usually meets the need for equipment or mechanisms that are more A-powered. The hydraulic system _ structure is more complicated and takes up space, and its application range is limited. The screw mechanism driven by the electric motor is smaller than the hydraulic system, and the n (four) (four) fine material is suitable for the inspection of the electric tailgate that does not require a large power, typical examples such as the electric tailgate of a small automobile, electric Doors and windows and curtains, electric opening and closing exhaust doors, electric window openers, etc., can be used as a power source for reading and using electricity. Traditionally, the screw mechanism driven by the electric motor is controlled by the forward and reverse rotation of the electric motor. Further, the screw load of the screw machine is used for the direct hybrid movement. The traditional screw mechanism acts as a linear motion on the interlocking load by the inertial force of t. It is not easy to achieve the exact stop requirement in the past, and it is one of the problems that the technical practitioners have tried to overcome for some of the precise stoppages that need to be stopped accurately.
