The utility model discloses an upright type folding mechanism for electric running machines. The function of a single lifting motor is mainly utilized to achieve multiple functions of the adjustment of framework inclination angles, upright fold and furl and the furl of handrail connecting rods, wherein the lifting motor and a drive screw rod are fixedly arranged between two pedestals. In addition, a slip tube with corresponding internal screw threads is arranged on the screw rod by screws, while the other end of the slip tube is pivoted and connected with a pivoted rotating rod, and the other end of the pivoted rotating rod is transversely connected with a front transverse rod and a handrail connecting rod. One end of a framework is pivoted and connected to an upright post of the pedestals, while the bottom end surface is respectively pivoted with a telescopic bunting member, a pull rod, and a push rod, which are respectively pivoted with the slip tube, the pivoted rotating rod and the handrail connecting rod. When the lifting motor is started so as to cause the screw rod to rotate in situ, forward and backward displacement is generated synchronously by the slip tube along with the screw rod. Thus, an expectation effect is achieved.
