[0033] A specific application of this embodiment is: when in use, put the workpiece on the top of the base 1, and then turn on the motor 22. After the motor 22 is turned on, the output shaft of the motor 22 drives the bidirectional threaded rod 23 to rotate. When the bidirectional threaded rod 23 rotates, the bidirectional threaded rod 23 drives the two threaded blocks 24 to start moving toward the center of the bidirectional threaded rod 23. When the threaded block 24 moves, the threaded block 24 drives the side connecting plate 25 to start moving toward the center of the base 1. When the connecting plate 25 moves, the connecting plate 25 drives one end of the hinged rod 26 to move toward the center. When one end of the hinged rod 26 moves toward the center, the hinged rod 26 The other end starts to move toward the center of the base 1. When one end of the hinged rod 26 moves toward the center, the hinged rod 26 drives the vertical plate 27 to move toward the center. When the vertical plate 27 moves toward the center, the vertical plate 27 drives the telescopic plate 28 on the side to move toward the center. When the telescopic plate 28 moves toward the center, the telescopic plate 28 drives the elastic rod 29 on the side to move toward the center. When the elastic rod 29 moves toward the center, the elastic rod 29 drives the elastic clamping plate 210 to move toward the center. When the elastic clamping plate 210 moves toward the center, the elastic clamping plate 210 clamps the workpiece above the base 1. By using the characteristics of the elastic clamping plate 210, the shape of the elastic clamping plate 210 can be changed, so as to better achieve the effect of clamping the workpiece, so that it can adapt to workpieces of different shapes and sizes, thereby having a wider range of applicability, reducing the need to replace the fixture, and improving production efficiency.

When the sliding rod 31 moves toward the center, the sliding rod 31 drives the reinforcing plate 32 on the side to start moving toward the center. When the reinforcing plate 32 moves toward the center, the reinforcing plate 32 clamps the workpiece above the base 1. When the reinforcing plate 32 is clamped, the reinforcing plate 32 is subjected to the squeezing force from the workpiece, and the reinforcing plate 32 begins to move outward. When the reinforcing plate 32 moves outward, the reinforcing plate 32 drives the sliding rod 31 on the side to also begin to move outward, so that the reinforcing plate 32 further reinforces the workpiece. At the same time, when the reinforcing plate 32 moves outward, the reinforcing plate 32 squeezes the compressed air bag 34 on the side. After the compressed air bag 34 is squeezed, the gas inside the compressed air bag 34 is ejected outward through the jet pipe 35, thereby performing an air blowing and cleaning operation on the workpiece above the base 1, thereby causing impurities on the surface of the workpiece to fall off, thereby improving the processing quality.
