Supporting device

The utility model discloses a supporting device. The supporting device comprises a supporting base and a plurality of transverse supporting frames, wherein the top of the supporting base is detachably connected each transverse supporting frame, the bottom of the supporting base is detachably connected with an external workbench, and the supporting base is perpendicular to each transverse supporting frame. When the supporting device is applied to pendulum shear equipment, tail billets can pass through the pendulum shear equipment during steel strip shearing, sable running of steel strips is guaranteed, and the abnormal phenomenon of head warping or deflection or tail blocking or the like is avoided, wherein tail blocking is caused due to the fact that the shorn tail billets recede under the action of interaction force.
