The utility model relates to a movable nail propping seat assembly. The movable nail propping seat assembly comprises a nail propping seat, a positioning clamp spring tube, a base cap connecting shaft, a clamp spring tube connector, a spring compression screw, a spring, a marble and a connecting pin. The base cap connection shaft is coaxially fixed to the nail propping seat. The base cap connecting shaft is hinged to the clamp spring tube connector through the connecting pin. A first marble groove shaped like a spherical cap is formed in the center of the lower end face of the lower inclined part of the base cap connecting shaft, and second marble grooves are symmetrically formed in the two sides with the first marble groove as a center. A second central stepped hole is formed in the clamp spring tube connector. The lower segment of the spring compression screw is screwed in the second central stepped hole of the clamp spring tube connector in a threaded mode. The upper segment of the spring compression screw is coaxially sleeved with the spring. The upper end of the marble is embedded in the first marble groove or any second marble groove. The lower end of the marble makes contact with the spring and compresses the spring so that the marble can be elastically supported by the spring. The lower segment of the clamp spring tube connector is inserted in the positioning clamp spring tube, and the clamp spring tube connector is in rigid connection with the positioning clamp spring tube.
