Hardware machining clamp

The utility model relates to the technical field of hardware machining clamps, in particular to a hardware machining clamp which comprises a U-shaped device fixing frame body, a hole is formed in the top of the U-shaped device fixing frame body, and a plurality of material clamping mechanisms are installed on the surface of the top of the U-shaped device fixing frame body. The material clamping mechanisms are installed at the top of the U-shaped device fixing frame body through screws, the telescopic adjusting mechanisms are installed outside the clamping mechanisms, the bearing mechanisms are installed in the middles of the telescopic adjusting mechanisms, and holes are formed in the bottoms of the bearing mechanisms. The bottom of the bearing mechanism is installed at the bottom end of the middle of the U-shaped device fixing frame body through bolts, and the pulley mechanism is installed at the bottom of the U-shaped device fixing frame body. Through the design that a sliding strip is arranged in a clampin
