Abstract

The present invention relates to a device for preventing hands from being clamped of slide rail closing. A spacing member which can move in real time corresponding to an inner rail and an outer rail is arranged at the rear part of a middle rail, has an elastic force action and makes constant lever type deflective swinging movement. A guiding sheet is formed at the rear end of the outer rail in the axis direction which can make the spacing member swing rightly. At the time of operation, once the inner rail, the middle rail and the outer rail are pulled out, the spacing member disengages from the guiding sheet and deflects. The spacing member can deflect at an angle opposite to the action end of the inner rail, is clamped and bunted at the rear end of the inner rail and is temporarily clamped and bunted when the inner rail is pushed in again, so the space for preventing the hands from being clamped is formed between the front ends of the inner rail and the middle rail. The inner rail pushes the middle rail, and the inner rail and the middle rail slide in the front of the outer rail. The spacing member is guided rightly through the guiding sheet to remove the state that the spacing member clamps and fixes the inner rail. Action and temporary stagnation are removed, so an operator can vigilantly release fingers to preventing the fingers from being clamped.
