The invention relates to the technical field of mechanical equipment, and discloses a mechanical supporting equipment with self-balancing function, which includes a base, a rectangular slot is opened on the top of the base, four sets of supporting mechanisms are arranged on the bottom of the base, and the supporting mechanisms include supporting columns, Four sets of supporting columns are respectively arranged at four right angles at the bottom of the base. The mechanical support device with self-balancing function, the present invention sets the support mechanism, the bottom end of the balance ball is set by the support column, the support spring and the bottom plate, the bottom plate is set on the ground so that the base and the mechanical body can be stable, and the top of the balance ball is set by setting The buffer column, the limit plate and the limit spring, under the joint elastic force of the limit spring and the support spring, enable the four sets of balance balls to be stably arranged in the corresponding balance chambers, and then two adjacent balance balls pass through the balance bar With a stable connection, the further stabilized balance ball enables the bottom plate to maintain the overall stability of the base.
