The invention discloses an indexing rotary type quick pressing clamp. The indexing rotary type quick pressing clamp comprises a pressure head, a regulating nut, a slide block, a pressure rod, a transverse rod, a connecting base, a rotary shaft, a base, a connecting plate, a steel ball, a spring, a force transmitting rod, a handle, a top rod and the like. Different from a way of mounting a plurality of sets of pressing clamps or additionally adopting different rotary mechanisms for pressing of different angles in the prior art, only one set of pressing clamp can be adopted to press workpieces at different angles, so that usage quantity of the pressing clamps can be reduced, and number of connecting holes in a bottom plate for fixing the pressing clamp is correspondingly reduced. The indexing rotary type quick pressing clamp has an indexing function, and can be used for positioning the angle more precisely; and meanwhile, advancing, retreating, ascending and descending of the pressure rod in the prior art are adopted through two wrenches. The advancing or retreating of the pressure rod is realized by only manually twisting the regulating nut, so that the indexing rotary type quick pressing clamp is very convenient.
