A clamping device for a narrow cavity comprises a power part; a clamping mechanism is arranged at the end of the power part and comprises a plurality of tong heads arranged in a matched mode, each tong head comprises a tong clamping face arranged on the inner side and a tong supporting face arranged on the outer side, a pressure sensor is arranged between the tong clamping face and the tong supporting face, and the pressure sensor is connected with the power part; a feedback damping mechanism is arranged on one side, close to the power part, of each tong head, is matched with each tong head, and is used for receiving signals of the pressure sensors and then changing the moving damping of the tong heads. By arranging the feedback damping mechanism, the motion trend of the tong head can be changed in time while a signal of the pressure sensor is sensed, so that a good negative feedback effect is achieved when the motion speed of the tong head needs to be changed, especially when the motion needs to be stopped i
