The utility model relates to an adopt perpendicular strutting arrangement of electric servo cylinder driven, mainly by inside and outside guide holder (1, 3), sliding sleeve (2), electric servo cylinder (18) with prevent rotating device, sliding sleeve (2) are located between inside and outside guide holder (1, 3), and in interior guide holder (1) is located to the cylinder body of electric servo cylinder (18), and the four is the telescopiform setting, it has force cell sensor (13) and prevents rotating device also to establish ties on jar pole (8), prevents being equipped with on the rotating device stroke dead stop (5), stroke adjusting nut (four to six -tenehs), switch buting iron (17) and proximity switch (20), the rod end of jar pole (8) is equipped with bulb (9) and work piece ball and socket base (10) are processed in the mountable. Its advantage is, axial dimensions is little, and it is good to support the rigidity, can realize servo soft spacing, travel switch, the triple protections of mechanical buting iron.
