[0002] Profiles are solid, straight bars of metal formed through plastic processing to a defined cross-sectional shape and size. Profiles come in a wide variety of sizes and types, and are used in a wide range of applications. During production and processing, profiles require clamping devices to secure them in place.

[0003] Patent No. CN202021607576.1 discloses an aluminum profile clamping device that is easy to clamp. In view of the problem that most existing aluminum profiles lack the function of clamping them during processing, resulting in low processing efficiency, the utility model realizes the function of quickly clamping aluminum profiles. By setting a bidirectional threaded rod, the bidirectional threaded rod is manually rotated so that the two threaded caps move closer to or away from each other, so that the second clamping plate is operated upward or downward, and different models of aluminum profiles are vertically clamped.

[0004] Existing profile clamping devices use a set of clamping plates to clamp the profile. These plates are positioned differently to clamp the profile in the vertical, horizontal, and front-to-back directions, making them suitable for only a small number of profiles. Different clamping devices are used depending on the type and specification of the profile, limiting their applicability. Utility Model Content

[0007] Preferably, a slide rail is fixedly provided on the two clamping plate seats, and a slide groove is provided on the side of the four sliding blocks facing away from the clamping plate. The two slide rails are slidably connected to the slide grooves of the two adjacent sliding blocks to improve the sliding stability of the sliding blocks.

[0008] Preferably, the two adjusting screws include a left-handed screw and a right-handed screw, and a centering rod is fixedly connected between the left-handed screw and the right-handed screw. The left-handed screw and the right-handed screw are connected by the centering rod so that the left-handed screw and the right-handed screw are coaxial.

[0009] Preferably, the left-hand screw and the right-hand screw are threadedly connected to the left nut and the right nut respectively, thereby realizing movement of the two sliding blocks in opposite directions.

[0010] Preferably, one end of the two adjusting screws is fixedly connected to a hand screw, and the two left-hand screws are respectively integrated with the two hand screws, and the staff rotates the adjusting screws by hand screwing.

[0011] Preferably, two of the first ejection plates are correspondingly arranged, and two of the second ejection plates are correspondingly arranged, and grooves are provided on opposite sides of the two first ejection plates. The two first ejection plates fix the pipes and profiles through the grooves to improve the stability of the pipes and profiles.

[0012] Compared with the existing technology, the beneficial effects of the utility model are: by manually twisting, the nut drives the ejector plate to move closer to the center, thereby playing a clamping role; the adjusting screw is divided into two parts with positive and negative teeth, and the four ejector plates are divided into two groups, which are clamped from the X and Y directions respectively, and can clamp most pipes and profiles, with a wide range of applications.
