A rail fast grounding clamp

Abstract

The utility model discloses a kind of steel rail fast grounding clamps, including base body, a pair of coupled clamping jaw is movably connected in the both sides of base body, a top block is movably connected between two clamping jaws, top block is below base body, shaft rod is movably provided with the top block on base body, shaft rod is stretched out by the top end of base body, spring is arranged between shaft rod and base body;When shaft rod is pressed down by external force, top block is pushed to open clamping jaw, when external force is removed, shaft rod resets under the pushing of spring and drives clamping jaw to close.The beneficial effects of the above technical solution are that: the clamping jaw set can be opened with one hand, and after contacting the rail, the grounding clamp can be fixed on the rail by releasing the hand.

Claims

1. A quick grounding clamp for rails, characterized in that, include: A base (100) has a pair of coupled grippers (200) movably connected to both sides of the base (100).
