The invention discloses a push-pull switchable carrying device. The push-pull switchable carrying device comprises a frame, a handle assembly and a plurality of wheel assemblies. The frame is provided with a containing space, and the handle assembly is movably connected with the near end of the frame and has a handle pushing posture in which the handle assembly is rotationally close to the frame and combined with the frame and a handle pulling posture in which the handle assembly is separated from the frame and relatively inclined. The wheel assembly is mounted at the bottom of the frame and comprises a first wheel assembly and a second wheel assembly which are close to the near end and the far end respectively, and the wheel assembly comprises a wheel seat, a wheel pivoted with the wheel seat through a connecting shaft and a movable locking piece for limiting the wheel from rotating around the connecting shaft; the wheel assembly has a universal state in which the wheels can deflect at will and a directional state in which the wheels can only move towards a specific direction; when the handle assembly is in a handle pushing posture, the first wheel assembly is in a directional state, and the second wheel assembly is in a universal state; when the handle assembly is in a handle pulling posture, the first wheel assembly is in a universal state, and the second wheel assembly is in a directional state. And the push-pull operation is convenient.

    本发明公开了一种可推拉切换的运载装置,包括框架、手把组件和多个车轮组件。框架具有一容置空间,手把组件与框架的近端活动连接,具有转动靠近框架并与其相结合的推把姿态以及脱开框架相对倾斜的拉把姿态;车轮组件安装于框架的底部并包括分别靠近近端和远端的第一车轮组件和第二车轮组件,车轮组件包括轮座、通过连接轴与轮座枢接的车轮以及可活动的限制车轮绕连接轴转动的锁止件,车轮组件具有车轮可以任意偏转的万向状态以及车轮仅可朝特定方向行进的定向状态;手把组件处于推把姿态时,第一车轮组件处于定向状态,第二车轮组件处于万向状态;手把组件处于拉把姿态时,第一车轮组件处于万向状态,第二车轮组件处于定向状态。方便推拉操作。
