[0026] Specifically, when the control assembly 1 provided in the mechanical fixture for sample transfer is started, it can synchronously adjust the first L-shaped connecting member 2 and the second L-shaped connecting member 3 to move towards or away from each other. By the movement of the first L-shaped connecting member 2 and the second L-shaped connecting member 3, the first clamping arm 4 and the second clamping arm 5 can be driven to move.
