Self-adaptive support

The utility model belongs to the field of bridge supports, and particularly relates to a self-adaptive support. Comprising an upper support and a lower support, the upper support is provided with a limiting table, and the upper support and the lower support are rotationally connected. A self-adaptive mechanism is arranged between the limiting table and the lower support; the self-adaptive mechanism comprises a first self-adaptive block, a self-adaptive shaft and a second self-adaptive block. The first self-adaptive block is fixedly connected with the limiting table. Or the self-adaptive block II is fixedly connected with the lower support; the self-adaptive shaft is in cambered surface fit with the first self-adaptive block, and the self-adaptive shaft is in cambered surface fit with the second self-adaptive block. The support can adjust and compensate the corner gap in the whole force transmission process, the support is prevented from being impacted, and the service life of the support is prolonged. 本实用新型属于
