A stroller. A stroller frame (1) comprises a left side support (2), a right side support (3), and a connecting frame (4). The left side support (2) and the right side support (3) are symmetrical. The connecting frame (4) is connected between the left side support (2) and the right side support (3). The left side support (2) comprises a left front frame (21), a left rear frame (22), a left side rod (23), a left connecting rod (24), a left pull rod (25), and a left push rod frame (26). A front part of the left connecting rod (24) is rotatably connected to the left front frame (21). The left pull rod (25) is rotatably connected to the left rear frame (22). The left push rod frame (26) is rotatably connected to an upper part of the left side rod (23). The left pull rod (25) is rotatably connected to a rear part of the left connecting rod (24).A lower part of the left push rod frame (26) is rotatably connected to an upper part of the left pull rod (25). An upper part of a left front wheel, an upper part of the left rear frame (22) and a lower part of the left side rod (23) are rotatably connected. When the stroller frame (1) is at an unfolded position, an included angle α is formed between the left front frame (21) and the left side rod (23), and an angle range of the included angle α is 165 to 195 degrees. After a frame locking mechanism of the stroller frame (1) is unlocked, the left side support (2) and the right side support (3) can be folded separately, and opposite rotate around the connecting frame (4) to draw close, so that the stroller frame (1) is at a folded position, the size of the stroller after folded is small, and the stroller is convenient to carry. |
