The invention discloses a pull rod folding mechanism of a buggy. The folding mechanism comprises a first bottom support, a second bottom support and backrest supports on the two sides of the buggy. The first bottom support and the second bottom support are hinged in an X manner, and the backrest supports on the two sides are symmetrically hinged to the upper faces of the two sides of the first bottom support; two hooks are symmetrically connected to the backrest supports on the two sides; the hooks can rotate around a connecting point, and two sleeves allowing the hooks to hang therein are symmetrically fixed to one end close to the backrest supports on the two sides, of the first bottom support; two transmission rods are symmetrically arranged between the second bottom support and the backrest supports on the two sides; and one ends of the two transmission rods are hinged to the second bottom support, and the other ends of the two transmission rods are hinged to the backrest supports. According to the principles of a three-connecting-rod structure and a four-connecting-rod mechanism, unfolding and folding of the buggy can be achieved, a backrest and a seat of the buggy can be folded together, and space occupied by the whole buggy can be reduced.
