Novel penetrating clamp

The utility model discloses a novel penetrating clamp which is installed on a guide rail of a photovoltaic support and comprises a conductive clamp, a sliding block and a bolt. The conductive clamp is matched above the sliding groove of the guide rail and is used for clamping a grounded wire, at least one spine is integrally formed on each of two sides of the conductive clamp, and the tip end of each spine downwards abuts against the upper surface of the guide rail; the sliding block is clamped and matched with the sliding groove of the guide rail; the bolt penetrates through the conductive clamp and is in threaded connection with the sliding block. When the bolt is locked, the spikes are tightly matched with the upper surface of the guide rail to pierce an oxidation film of the guide rail. According to the utility model, the spines are integrally formed on the side edges of the conductive clamp, so that the production process of the conductive clamp is simplified, and the spines can pierce an oxidation film
