[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4 As shown, a metalworking fixture includes a support plate 1. Square grooves 13 are formed on both sides of the top of the support plate 1. A slider 14 is slidably connected to the inner wall of each square groove 13. The top of the slider 14 is fixedly connected to the bottom of a second square block 3, thereby improving the stability of the second square block 3 during movement. A first square block 2 is fixedly connected to one side of the top of the support plate 1, and a second square block 3 is slidably connected to the other side of the top of the support plate 1. Fixing blocks 4 are fixedly connected to the opposing sides of both the first square block 2 and the second square block 3. Slide plates 5 are slidably connected to both sides inside the first square block 2 and the second square block 3. An extension plate 6 is fixedly connected to one side of the top of the slide plate 5. A sliding rod 7 is slidably connected inside the extension plate 6, with one end of the sliding rod 7 connected to the first square block 3. The inner walls of the first square block 2 and the second square block 3 are fixedly connected. A spring 8 is sleeved on the surface of the slide rod 7. The two ends of the spring 8 are fixedly connected to one side of the extension plate 6 and the inner walls of the first square block 2 and the second square block 3, respectively. A movable plate 9 is fixedly connected to one end of the slide plate 5. A clamping block 10 is rotatably connected to the top of the movable plate 9. A fixing groove 19 is opened on one side of the clamping block 10. Fixing structures 11 are provided on both sides of the top of the clamping block 10. The fixing structure 11 includes a connecting plate 111 fixedly connected to the left and right sides of the first square block 2 and the second square block 3 facing each other. A fixing pin 112 is slidably connected inside the connecting plate 111. Circular grooves 113 are opened on the front and back sides of the top of the clamping block 10. The other end of the fixing pin 112 passes through the connecting plate 111 and cooperates with the inside of the circular groove 113.

[0023] When the clamping blocks 10 on both sides move, the operator can pull out the fixing pin 112 to release the clamping block 10 from its limit. After the clamping block 10 moves to the starting position, the operator can insert the fixing pin 112 through the connecting plate 111 and into the circular groove 113 to limit and fix the clamping block 10. A drive structure 12 for use with the second square block 3 is provided on one side of the top of the support plate 1. The drive structure 12 includes a support block 121 fixedly connected to one side of the top of the support plate 1. A threaded rod 122 is threadedly connected inside the support block 121. One end of the threaded rod 122 is rotatably connected to one side of the second square block 3. The other end of the threaded rod 122 is fixedly connected to a handwheel 123. When the second square block 3 moves, the operator needs to turn the handwheel 123 and drive the threaded rod 122 to rotate together, thereby driving the second square block 3 to move.

[0024] Several locking blocks 16 are fixedly connected to the opposite side of the first square block 2 and the second square block 3. Several locking slots 15 are opened on both sides of the clamping blocks 10. The locking blocks 16 and the locking slots 15 are used together. When the clamping blocks 10 on both sides move, so that the locking blocks 16 are located inside the locking slots 15, the stability of the clamping blocks 10 after they are attached can be increased.

[0025] The front and rear sides of both sides of the support plate 1 are fixedly connected to the fixing plate 17. The fixing plate 17 is internally threaded with bolts 18. When the operator places the equipment on the machine tool, the bolts 18 can be tightened with external tools to fix it on the machine tool, which makes it easy for the operator to install and disassemble the equipment.

[0026] Working principle: When processing metal, the operator first places the fixture on the machine tool and secures it to the machine tool with bolts 18 using external tools. Then, the operator places a round piece of metal on the fixture. At this point, the operator needs to turn the handwheel 123, which in turn rotates the threaded rod 122, thus moving the second square block 3 to process the clamped round metal. When processing the square metal, the operator can pull the clamping blocks 10 on both sides. Then, the operator needs to pull out the fixing pin 112 to release the limit on the clamping blocks 10. Next, pulling the clamping blocks 10 will move the moving plate 9 and the sliding plate 5 together. When the skateboard 5 moves, it can cause the extension plate 6 to compress the spring 8 during the movement. After the clamping block 10 is pulled out a certain distance, the operator needs to rotate the clamping block 10 so that the flat sides of the two clamping blocks 10 face each other. After the rotation is completed, the operator releases the pulling force on the clamping block 10. At this time, the elastic force of the spring 8 itself can push the extension plate 6 and the skateboard 5 to move, and drive the moving plate 9 and the clamping block 10 to move, so that the two clamping blocks 10 are respectively attached to the first square block 2 and the second square block 3. Then the square metal can be placed on the fixed block 4, and then the handwheel 123 is rotated to move the second square block 3 and clamp the square metal.
