Certain connecting rod 34, the front portion of which is rotatably connected with the front right frame 31 by a third straight shaft 313; a right pulling rod 35, which is pivotally connected with the right rear frame 32 by a fourth right axle 314, and which is pivotally connected with the right rear portion of the connecting rod 34 by a fifth straight axle 315; Likewise, the fifth right axis 315 can be located in front of or behind the fourth right axis 314, in this embodiment, the fifth right axis 315 is located opposite the fourth right axis 314; and a right-hand push frame of the rod 36, which is rotatably connected with the upper portion of the right-hand rod 33 by a sixth right axis 316, and the lower portion of the right-hand push rod structure 36 is rotatably connected with the top of the right drawbar 35 by a right seventh axle 317.
    [0040] The left connecting rod frame 26 and the right connecting rod frame 36, respectively, are an integrated rod. The frame locking mechanism is arranged between the left push rod structure 26 and the left side rod 23, and between the right push rod structure 36 and the right rod 33. frame can also be arranged in other positions, such as, between the left push rod frame 26, and the left drawbar 25, and between the right push rod frame 36 and the right drawbar 35. of the frame locking mechanism is not involved in the technical aspects of the invention, and therefore will not be described in more detail.
    [0041] In the left support frame 2, the left front frame 21, the left rear frame 22, the left of the connecting rod 24 and the draw rod left 25 constitute a four-rod mechanism, and the left rear frame 22, the rod left 23, the left push rod frame 26 and the left draw rod 25 also constitute a four rod mechanism. Correspondingly, the support frame 3 on the right and left of the support structure 2 are symmetrical to each other.
    [0042] The connecting frame 4 comprises: a front transverse rod 41, one end of the front transverse rod 41 is rotatably connected with the left front structure 21 by a left ninth axis 411, and the other end is rotatably connected with the front structure right 31 by a right ninth axis 421; a rear cross rod 42, one end of the rear cross rod 42 is rotatably connected with the left rear frame 22 by a left tenth axis 412, and the other end is rotatably connected with the right rear frame 32 by a tenth right axis 422; and an upper cross rod 43, one end of the upper cross bar 43 is rotatably connected with the left push rod 26 through a left XI axis 413, and the other end is rotatably connected with the right push rod structure 36 by 1/11 right axis 423.

Preferably, an angle α' is formed between the right front frame 31 and the shank 33 to the right, and the angle α' is in the range of 165°-195°, preferably 170°-185°. Rather, the left front frame 21 and the left side rod 23 tend to be straight and the left support frame 2 and the right support frame 3 are symmetrical with respect to each other, such that the frame has little volume when it is in the folded position.
    [0044] When frame 1 is in the folded position, the shaft axis of the 411th axis and the left ninth axis of the shaft axis of the left tenth axis 412 are parallel to the axis of the left axis shaft XI 413, and the axis of the left axis of the ninth axis right axis 421 and the right 10th axis axis shaft 422 are parallel to the right XI axis axis 423. Better, when the frame is in the folded position, the left ninth axis axis 411 and the left axis axis tenth axis 412 coincide with the axis of the left axis XI 413, and the axis of the ninth axis of the right axis 421 and the axis of the axis of the tenth axis of the right axis 422 coincide with the axis of the axis of the right axis XI axis 423, in this way, when the frame 1 is in the folded position, the left support frame 2 and the right support frame 3 can approach well in relation to the connecting frame 4. Two front limiting mechanisms, respectively, are arranged between the two ends of the front cross rod 41 and the left front frame 21 eae right front frame 31. Two rear limiting mechanisms, respectively, are arranged between the two ends of the rear cross rod 42 and the left rear frame 22 and the right rear frame 32. two upper limiting mechanisms, respectively, are arranged between the two ends. of the upper transverse rod 43 and the left connecting rod frame 26 and the right connecting rod frame 36. the above limiting mechanisms are not involved by the technical aspects of the invention, and provided that, when the frame 1 is in the unfolded position, having a front mechanism stopper as an example, while the left front frame 12 can rotate with respect to the front transverse rod 41 only in one direction, and cannot rotate in the other direction. For example, two projections are provided on the two ends of the front cross strut 41, when the frame 1 is in the unfolded position, the left front frame 12 and the right front frame 22 respectively press the two protrusions over the two ends of the front cross strut 41.
    [0045] In order to make the frame 1 more stable in the unfolded position, preferably the connecting frame 4 also comprises a cross connecting rod 44, one end of the cross connecting rod 44 is rotatably connected with the left side of the connecting rod 24 by a left XII shaft 414, and the other end is rotatably connected with the right connecting rod 34 by 1/12 right axis 424, the left axis ninth axis shaft 411, the left tenth axis shaft 412 and of the axis of the left axis XI axis 413 are parallel or coincident with the axis of the left axis 414. Correspondingly XII, and of the axis of the ninth axis of the right axis 421, the axis of the tenth axis of the right axis 422 and the axis of the shaft right XI axis 423 are parallel to or coincident with the axis of the twelfth axis axis 424 to the right. Two connecting rod limiting mechanisms, respectively, are arranged between the two ends of the cross connecting rod 44 and the connecting rod 24 left and right of the connecting rod 34. The connecting rod limiting mechanisms are similar to forward limiting mechanisms as described above. When the frame is in the folded position, the length of the baby carriage is 250 mm, the width of the baby carriage is 126 mm, and the height of the baby carriage is 430 mm. The width and length of frame 1 after folding will be affected by the thickness of the rods of frame 1. During the folding of frame 1, i.e. in the course of folding the left supporting frame 2 and the right supporting frame 3 , particularly taking the left support structure 2, as an example, the left push rod structure 26 is moved vertically downwards, the left rod 23 is rotated back and forth by the second left axis 212 and the pull rod left 25 is rotated backwards and downwards by the left fourth axle 214, and approaches the left rear frame 22 to drive the left connecting rod 24 such that the left front frame 21 and the left rear frame 22 approach each other. the other in a first bent state under the effect of the left connecting rod 24. then the left support frame 2 and the right support frame 3 are turned at a 90° angle to each other and bent to the connecting frame 4 in asecond folded state, that is, structure 1 is in the folded position.
