The invention discloses a core shaft assembly with a force limiting stopping function. The core shaft assembly comprises a core shaft body, a force limiting rod, a locking nut, a locking head, a pre-tightening wheel, a shaft head and a stopping connecting part. The first end of the locking head is clamped to part of the inner circumferential wall of the pre-tightening wheel in the axial direction and abuts against the radial end face of the pre-tightening wheel in the axial direction through the first end. An external thread connecting part is arranged on the outer wall of the second end of the locking head; the locking end of the shaft head is far away from the pre-tightening wheel and is used for locking; the connecting end of the shaft head is inserted into the other part of the inner circumferential wall of the pre-tightening wheel in the axial direction so as to be opposite to the first end of the locking head. The stop connecting part is arranged between the first end of the locking head and the connecting end of the shaft head which are oppositely arranged, and is used for connecting the first end of the locking head with the connecting end of the shaft head; the locking nut comprises an internal thread connecting part located on the inner wall of the nut body and a first limiting part located on the outer wall of the nut body, and the internal thread connecting part is in threaded connection with the external thread connecting part at the second end of the locking head.
