This creation relates to a stroller, especially a stroller that is simple in construction.

According to the improvement of the quality of modern life, the average family will purchase a stroller to facilitate the baby to travel. However, in view of the excessive volume of the stroller, the strollers currently on the market are often provided with a folding structure, so that the stroller can be folded to reduce the space when not in use, so that the stroller can be stored.

For example, the Chinese Patent No. M295071 discloses a baby carriage comprising a baby carriage skeleton, a positioning seat, a snap pin and a release device. The baby carriage skeleton has a front leg tube, a rear leg tube and a handle. The positioning seat is connected to the rear leg tube and pivotally connected to the front leg tube and the handle tube. The engaging pin is movably disposed on the positioning seat, and the release device is disposed on the stroller frame and the card is engaged Between the pins.
