Building construction steel bar cutting device

The invention belongs to the technical field of building construction, and discloses a building construction steel bar cutting device which comprises a supporting table, the top of the supporting table is fixedly connected with a protective positioning cover, the periphery of the upper surface of the supporting table is fixedly connected with limiting vertical rods, and the tops of the limiting vertical rods are fixedly connected with a fixing plate. The top of the fixing plate is fixedly connected with an electric hydraulic rod. Through cooperation of a protective positioning cover, a limiting vertical rod, a top plate, a feeding mechanism and other structures, the device has the effect of automatically adjusting steel bar feeding operation so as to improve the shearing efficiency, through operation of an electric hydraulic rod, a first spring is compressed, meanwhile, a shearing block can move downwards into an inner cavity of a shearing opening, and the shearing efficiency is improved. And at the moment, t
