Convenient graphite clamp

The utility model provides a convenient graphite clamp, and belongs to the technical field of clamps. The convenient graphite clamp comprises a supporting and limiting piece and a clamping assembly. The supporting and limiting piece comprises a fixing plate and a limiting strip, the limiting strip is fixedly connected to the upper surface of the fixing plate, the clamping assembly comprises a fixing frame, a supporting column, a clamping part and a limiting piece, one end of the pin column penetrates through the side wall of the fixing frame and the side wall of the supporting column and extends into the adsorption box, and the limiting piece is fixedly connected to the clamping part. And one end of the pin column is adsorbed with the inner wall of the adsorption box. Through the design and the overall design of the device, the conventional graphite clamp design is optimized, on one hand, the conventional complex design is reduced, the steps such as frequent error correction and adjustment are not needed when
