The invention discloses a combined spring bolt hole device. The combined spring bolt hole device comprises a body and a guide body connected to the body in a clamping mode. A spring bolt hole is formed after the body and the guide body are connected in the clamping mode. The inner wall, blocking a spring bolt in the door opening process, of the spring bolt hole serves as a blocking wall which is fixedly connected to the guide body. Due to the fact that the guide body is connected to the body in the clamping mode, the guide body is prone to disengagement from the body under the condition of the large force, and damage caused to doors and/or lock settings when people force an entrance into a room is reduced.
