Feeding device and sawing machine thereof

The feeding device comprises a feeding mechanism, the feeding mechanism comprises an L-shaped rod, a strip-shaped cavity is formed in the L-shaped rod, two movable blocks are connected to an inner cavity of the strip-shaped cavity in a sliding and sleeved mode, a clamping assembly is arranged on the front face of one movable block, and a length limiting assembly is arranged on the front face of the other movable block. By means of the arrangement mode that the feeding mechanism is matched with the sawing machine, the two movable blocks and the clamping assembly are matched to drive a plate to be cut to stably conduct feeding work, and after the first plate is cut, the movable length of the side of the plate can be locked through the length limiting assembly; and in the subsequent cutting work of the plates with the same specification, an operator does not need to worry about controlling the cutting length, and the convenience of the semi-automatic sawing machine for coping with the large-batch plates with the
