The multi-axis fatigue testing clamp comprises two relative clamp bodies, wherein a clamping end of the rear part of each clamp body is composed of an extending main shaft and an extending sleeve; an inner thread is arranged in the front end of each extending main shaft and is matched with an outer thread of the rear part of a connection shaft at the rear end of an arc-shaped clamp; an inwards concave surface of the front end of the arc-shaped clamp is provided with a plurality of locking devices which form different angles with the vertical direction; the structure of each locking device is as follows: the inward concave surface of the arc-shaped clamp is provided with a lug boss with a blind hole; a conduction cushion block is arranged in the blind hole; a test sample connection block covers the conduction cushion block, and a limiting tooth of the test sample connection block is matched with a limiting groove in a tabletop of the lug boss; an annular groove adapted with the side wall of a locking cover is formed in the periphery of the lug boss; the locking cover covers the test sample connection block and the locking cover is connected to the lug boss through a thread; a locking cover is provided with a through hole; and the test sample connection block is provided with an inner thread through hole. The clamp is matched with the single-axis high-cycle fatigue testing machine to be tried, and can be used for carrying out high-cycle and multi-axis test researches on a test sample.
