The invention relates to an automatic lifting device. The automatic lifting device is installed between a wheel at the bottom of a loading device and a wheel support, and mainly comprises a support combination piece, a wheel combination block, a second clamped connection piece and a baffle. In particular, the automatic lifting device is simply installed between the wheel and the support; in this way, when the loading device, such as an infusion support, an office chair, an industrial chair, an industrial desk or a trunk, with the wheel and the wheel support encounters a barrier in the front during movement, the wheel at the bottom of the infusion support can be automatically lifted and go over the barrier under the effect of the automatic lifting device, and therefore falling injuries caused by the fact that a user is influenced by the barrier in the front when the loading device is moved can be effectively prevented through the design.
