In the traditional installation method, limit switches are respectively arranged at the two ends of the stroke of the electric mechanism, and are triggered when the electric mechanism is retracted into place and extended out of place through a specific structure. Because of the error accumulation of the assembly, the position of the limit switch is usually required to be continuously adjusted after the electric mechanism is assembled, so as to ensure the limit precision of the micro switch. The mounting method is time-consuming and labor-consuming, the reliability of the micro switch is poor due to the fact that the accuracy positions of the mounting surfaces are different, the micro switch is prone to faults after a period of operation, and if the number of the micro switches is increased to increase redundancy, the reliability of the micro switch is not obviously improved due to the mounting problem.
