Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for an adjustable sheet metal stamping clamping mechanism, including a hollow fixed base 1. Two support plates 2 are provided on the top of the hollow fixed base 1, and an adjustment structure is provided between the two support plates 2. Two long gears 4 are provided inside the hollow fixed base 1, with both ends of the two long gears 4 passing through the inner side of the hollow fixed base 1 and rotatably connected to it. Gear 5 is fixedly connected to the outer side of one end of each of the two long gears 4, and the two gears 5 mesh with each other. One end of one of the long gears 4 is provided with a worm gear 6 and a worm 7. The worm gear 6 is fixedly connected to one end of one of the long gears 4, and the worm 7 is meshed with the outer side of the worm gear 6. A support 70 is rotatably connected to the outer side of the worm 7, and the support 70 is fixedly connected to the outer side of the hollow fixed base 1. One end of the worm 7 is mounted on... The device is equipped with a throttle handle 2. Two long gears 4 are meshed with racks 8 on their outer sides. Two racks 8 are fixedly connected to connecting plates 9 on their outer sides. The top of the hollow fixed base 1 has a long groove 100. The two racks 8 and the two connecting plates 9 are all located inside the long groove 100. One end of each connecting plate 9 is fixedly connected to a connecting rod 10. A sliding connection structure is provided between the connecting rod 10 and the support plate 2. The sliding connection structure includes a groove 200 and a protruding rod 300. The groove 200 is located on the outer side of the support plate 2. The protruding rod 300 is fixedly connected to the outer side of the connecting rod 10. The protruding rod 300 is located inside the groove 200 and is slidably connected to the support plate 2. A pressure plate 3 is fixedly connected to the outer side of the connecting rod 10. The pressure plate 3 is located on the top of the support plate 2. Rubber anti-slip pads are installed on the opposite side of the pressure plate 3 and the support plate 2.

[0024] Specifically, when the throttle handle is turned, the worm gear 7 meshes with the worm wheel 6. The worm wheel 6 drives one of the gears 5 to rotate through one of the long gears 4. One of the gears 5 meshes with the other gear 5. The two long gears 4 rotate in opposite directions and mesh with the two racks 8 respectively. The two racks 8 pull the two connecting rods 10 downward through the two connecting plates 9 respectively. The two protruding rods 300 slide downward in the two protruding grooves 200 respectively. Therefore, the two connecting rods 10 drive the two pressure plates 3 to move downward, thereby fixing the sheet metal parts placed between the two support plates 2. This structural design makes it convenient for personnel to operate and improves the practicality of the device.

[0025] Example: Figure 1- Figure 2 As shown, the adjustment structure includes four U-shaped rods 11, arranged in pairs. Two pairs of U-shaped rods 11 are fixedly connected to one side of two support plates 2. One end of each pair of U-shaped rods 11 passes through the outside of the hollow fixed base 1 and extends into the interior of the hollow fixed base 1. Both pairs of U-shaped rods 11 are slidably connected to the hollow fixed base 1. The adjustment structure also includes two threaded rods 13, both of which are located inside the hollow fixed base 1. Both ends of each threaded rod 13 pass through the inner side of the hollow fixed base 1 and are rotatably connected to the hollow fixed base 1. Both threaded rods 13 are threaded with connecting blocks 12 on their outer sides. The two connecting blocks 12 are fixedly connected to two U-shaped rods 11 respectively. Gears 14 are fixedly connected to one end of each of the two threaded rods 13. The two gears 14 mesh with each other. One end of one threaded rod 13 is fixedly connected with a worm gear 15. A worm 16 is meshed with the outer side of the worm gear 15. A support 160 is rotatably connected to the outer side of the worm 16. The support 160 is fixedly connected to the outer side of the hollow fixed seat 1. A throttle handle is installed at one end of the worm 16.

[0026] Specifically, when the throttle is turned, the worm gear 16 meshes with the worm wheel 15. The worm wheel 15 drives one of the gears 14 to rotate through one of the threaded rods 13. One of the gears 14 meshes with the other gear 14, thus causing the two threaded rods 13 to rotate in opposite directions. The two threaded rods 13 are threadedly connected to two connecting blocks 12 respectively. The two connecting blocks 12 drive two of the U-shaped rods 11 to move in opposite directions, thus causing the two support plates 2 to move in opposite directions, which can support sheet metal parts of various sizes.
