Abstract
The utility model discloses a stretcher which comprises a stretcher body, a front pair of supporting legs and a rear pair of supporting legs. The supporting legs are respectively fixed on the stretcher body. The stretcher is characterized in that a universal star wheel set is arranged at the lower end of each supporting leg, and each universal star wheel set comprises a fixed disc, a star wheel set support and a star wheel set, wherein the fixed disc is connected with the star wheel set support through a bearing, the axis of the bearing perpendicularly passes through the circle center of the fixed disc, the star wheel set is mounted on the star wheel set support and comprises a hub and star wheels evenly distributed on the hub in an annular shape, and the number of the star wheels is at least three. Compared with the prior art, the universal star wheel sets are arranged at the lower ends of the supporting legs of the stretcher, therefore the stretcher is enabled to turn directions flexibly and can be adapt to flat ground, bumpy roads and stairs, and work difficulty of medical staff is reduced.
