A vaginal dilator having side blades or having upper and lower blades comprising accessorial blades includes an upper blade (1), a press handle (3), a lower blade (2) and a handle (4). The upper blade (1) is connected with the lower blade (2) by a pin (5). The press handle (3) is engaged with the handle (4) by a first dilating fixation device. The vaginal dilator having side blades also includes a circular-arc movable locating sleeve (8) rotationally connected with the upper blade (1). Each end of the sleeve (8) is provided with a mounting base (11). The mounting base (11) is provided with a joint cavity for receiving a side blade (12) which can be retracted between the upper and lower blades (1, 2). The back portion of the side blade (12) is provided with a second dilating fixation device engaged with the back end of the upper blade (1) or a locating buckle (15) of the mounting base (11). A channel (18), a channel cover and a slot for inserting the channel cover are provided in the side blade (12). The vaginal dilator having upper and lower blades comprising accessorial blades also includes an upper accessorial blade (36) and a lower accessorial blade (37).
