The invention discloses a combined type upper shaft clamp for a semitrailer. The combined type upper shaft clamp comprises an upper shaft clamp body and a base plate. Four conical upper shaft clamp holes which are symmetric from left to right and from front to back are formed in a base of the upper shaft clamp body 1, the base plate is provided with two conical bosses matched with the conical upper shaft clamp holes, and two conical base plate holes are formed in the symmetric parts under the conical bosses. According to the invention, 17-mm thick structures, 30-mm thick structures and 43-mm thick structures respectively adopted in existing upper shaft clamps are improved; the 17-mm thick upper shaft clamp and the base plate are connected in a matched mode through different structure combinations, so that the variety of the upper shaft clamps is reduced, the degree of standardization is improved, and the weight of the upper shaft clamps is lowered to a certain degree through the structures. In addition, the operation is easy, and the labor intensity is greatly lowered.
