An apparatus for measuring blood coagulation data, in which blood to be measured is contained in a blood cup and a lid of the blood cup, comprising: a blood cup support; a detachment mechanism; a rotary shaft; and a pushing pin, wherein the blood cup support is used for supporting the blood cup that is not used and the lid of the blood cup, driving, under a first driving force, the blood cup that is not used and the lid of the blood cup to ascend until the lid of the unused blood cup is connected to the rotary shaft, and driving, under a second driving force, a blood cup that is used to descend, wherein the detachment mechanism is used for separating, under the second driving force, the lid of the used blood cup from the rotary shaft, wherein the detachment mechanism is of a plate structure provided with a through hole, the rotary shaft passes through the through hole in the middle of the detachment mechanism and is not in contact with the detachment mechanism, the detachment mechanism is used for moving towards the end part of the rotary shaft under the second driving force, separating the used lid of the blood cup, which is connected to the end part of the rotary shaft in an interference manner, from the rotary shaft, and enabling the lid of the blood cup, which is separated from the rotary shaft, to fall onto the used blood cup, wherein a through hole is formed in the bottom of the blood cup support which is of the cup-shaped structure and allows the fixed pushing pin to pass through, and wherein the pushing pin is used for contacting the bottom of the used blood cup after the blood cup support drives the used blood cup to descend by a set distance, and separating the blood cup support and the used blood cup which are connected in an interference manner when the blood cup support continues to descend. a blood cup support; a detachment mechanism; a rotary shaft; and a pushing pin, wherein the blood cup support is used for supporting the blood cup that is not used and the lid of the blood cup, driving, under a first driving force, the blood cup that is not used and the lid of the blood cup to ascend until the lid of the unused blood cup is connected to the rotary shaft, and driving, under a second driving force, a blood cup that is used to descend, wherein the detachment mechanism is used for separating, under the second driving force, the lid of the used blood cup from the rotary shaft, wherein the detachment mechanism is of a plate structure provided with a through hole, the rotary shaft passes through the through hole in the middle of the detachment mechanism and is not in contact with the detachment mechanism, the detachment mechanism is used for moving towards the end part of the rotary shaft under the second driving force, separating the used lid of the blood cup, which is connected to the end part of the rotary shaft in an interference manner, from the rotary shaft, and enabling the lid of the blood cup, which is separated from the rotary shaft, to fall onto the used blood cup, wherein a through hole is formed in the bottom of the blood cup support which is of the cup-shaped structure and allows the fixed pushing pin to pass through, and wherein the pushing pin is used for contacting the bottom of the used blood cup after the blood cup support drives the used blood cup to descend by a set distance, and separating the blood cup support and the used blood cup which are connected in an interference manner when the blood cup support continues to descend.
