[0010] The beneficial effects produced by the present utility model are as follows: An anti-retreat hinge clamping mechanism is proposed. By arranging a hinge mechanism between the guide shaft and the power device, the expansion and contraction of the power device are transmitted to the connecting rod for clamping, solving the problem that during the movement of a heavy workpiece, the impact generated by the collision causes the limit structure to fluctuate, resulting in severe shaking of the workpiece. By making the expansion and contraction direction of the power device perpendicular to the direction of the hinge mechanism, when the workpiece is accidentally collided, most of the generated force is absorbed by the hinge mechanism, and only a small part of the force is transmitted to the telescopic power device, thus playing an anti-retreat role and solving the situation that due to the bad collision during the operation process, the workpiece positioning is inaccurate and the subsequent production accuracy does not meet the standard.

[0020] Brief description of the working principle: Under normal circumstances, the guide shaft 12, the first hinge 7 and the second hinge 10 are in a horizontal state, and this is the clamping state at this time. When it is necessary to loosen, the telescopic power device 3 is started, so that the first hinge 7 and the second hinge 10 form a certain angle, thereby changing their support length, driving the guide shaft 12 to retract to reach the loosening state.
