[0002] Traditional metal clamping equipment includes bench vises, gantry vises, and other metalworking fixtures, as shown in the figure below. These traditional fixtures share a common feature: they rely on the forward and backward movement of a lead screw to tighten or loosen the metal parts. Each tightening and loosening requires the lead screw to travel back and forth, which is time-consuming, prone to instability and deformation as the lead screw wears down, and suffers from the inability to change the fixture model due to its fixed design, making it susceptible to uneven stress and deformation when fixing different metal parts such as round steel, flat steel, angle steel, and channel steel.

[0003] The aforementioned tools have no impact on the processing efficiency of individual metal parts, but when hundreds or thousands of metal parts are mass-produced, their low efficiency becomes obvious, with the wasted time mainly spent in the process of tightening and loosening the clamps. Summary of the Invention:

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a simple and quick metal fixing clamp that is small in size, easy to use, and highly applicable.

The base plate and the pressure strip are connected on both sides by fully threaded screws. The middle section of the pressure strip has two symmetrical mounting holes of the same size. A spring is provided above each of the two mounting holes. A solid rod extends downward through the spring and the mounting holes. The lower end of the solid rod is connected to the movable plate, and the upper end of the solid rod is provided with a rod cap. The clamp also includes a horizontal shaft located above the rod cap. Support members are provided on both sides of the pressure strip. The top of the support members is provided with a bearing support ring. The two ends of the horizontal shaft are respectively fitted into the bearing support rings on both sides. A downward pressure lever is provided in the middle of the horizontal shaft. An eccentric cam is provided at the position corresponding to the two rod caps in the middle section of the horizontal shaft. The top surface of the rod cap is provided with a groove that matches the eccentric cam.

[0007] Preferably, the base plate has fixing nuts on both sides, and the pressure strip has through holes at the positions of the nuts on both sides of the base plate corresponding to the positions of the nuts on both sides for the threaded screw to pass through. Positioning nuts are provided on the upper and lower sides of the through holes respectively.

[0008] Preferably, the bottom surface of the movable plate is provided with an upper fixed plate, the top surface of the base plate is provided with a lower fixed plate, and a clamping mold matching the workpiece to be clamped is set between the upper fixed plate and the lower fixed plate.

[0009] Preferably, the movable plate has four elongated fixing holes, and the four top corners of the upper fixing plate are clamped between the four fixing holes by adjusting screws and adjusting nuts; the base plate has four fixing holes, and the four top corners of the lower fixing plate are clamped between the four fixing holes by adjusting screws and adjusting nuts.
