description The utility model relates to the technical field of safety protection devices, and discloses a safety protection device for well drilling in a subsidence area, which comprises two fixing seats and two protection cross rods, the two fixing seats are symmetrically distributed left and right, and the two protection cross rods are symmetrically distributed up and down. According to the safety protection device for well drilling in the subsidence area, second threaded rods are arranged, the left second threaded rod and the right second threaded rod are rotated to make two threaded blocks move oppositely, through cooperation of the threaded blocks and connecting shafts, a first connecting plate and a second connecting plate move relatively, and the second connecting plate moves to drive a clamping block to move to be disengaged from a protection transverse rod; and then the two supporting columns are moved towards the opposite sides, so that the protective cross rods are separated from the connecting frames, the pr
