When the second gear 14 rotates, it will drive the rotating shaft 18 to rotate together. When the rotating shaft 18 rotates, it will drive the first connecting plate 15 and the second connecting plate 16 to move together and make them close to the workpiece. At this time, a pair of first connecting plates 15 will approach the workpiece at the same time, and the second connecting plate 16 will contact the workpiece when it moves. Because the second connecting plate 16 is inclined, the workpiece and the second connecting plate 16 will move along the surface of the second connecting plate 16 when they contact, so that the position of the workpiece will be adjusted. When the first connecting plate 15 contacts the surface of the workpiece, the workpiece will be fixed under the extrusion of the first connecting plate 15 and the second connecting plate 16. Finally, the staff can operate the cutting machine to cut the workpiece; the first connecting plate 15 and the second connecting plate 16 will approach the workpiece with the rotating shaft 18 under the meshing action of the first gear 13 and the second gear 14, and the workpiece will move along the surface of the second connecting plate 16, so that the device can locate the position of the workpiece and improve the accuracy of the position during subsequent workpiece cutting.

[0027] See also Figures 3 to 5As shown, the middle of the first connecting plate 15 is connected with the air pipe 2; the first connecting plate 15 and the second connecting plate 16 are in a connected relationship; a plurality of circular holes 22 are opened in the middle of the first connecting plate 15 and the second connecting plate 16; a plurality of suction cups 23 are fixedly connected to the middle of the first connecting plate 15 and the second connecting plate 16; the suction cups 23 and the circular holes 22 are correspondingly arranged and in a connected relationship; when the device is started, the staff can connect the air pipe 2 to an external air pump so that the air pump will pump air into the air pipe 2, and the air flow will enter the circular holes 22 from the outside. After entering the interior of the trachea 2, the workpiece passes through the first connecting plate 15 and the second connecting plate 16. At this time, a negative pressure state is formed at the circular hole 22. After the workpiece contacts the first connecting plate 15 and the second connecting plate 16, it will also contact the suction cup 23. Because the circular hole 22 is in a negative pressure state, the workpiece will be adsorbed and fixed by the suction cup 23 after contacting the suction cup 23, thereby increasing the contact area between the device and the workpiece; after the workpiece contacts the suction cup 23, it will be adsorbed and fixed by the suction cup 23, thereby enhancing the fixing effect of the device on the workpiece and reducing the shaking and deviation of the workpiece during cutting.

[0028] See also Figure 5 As shown, the inner walls of the first connecting plate 15 and the second connecting plate 16 are fixedly connected with a plurality of fixing seats 3; a spring 32 is fixedly connected to the middle of the fixing seat 3; a slide plate 33 is fixedly connected to the end of the spring 32; the slide plate 33 and the circular hole 22 are in sliding fit; a slide bar 34 is fixedly connected to the middle of the slide plate 33; when the workpiece comes into contact with the suction cup 23, it will also come into contact with the slide bar 34. After the workpiece squeezes the slide bar 34, the slide bar 34 will move with the slide plate 33 and put the spring 32 in a compressed state. At this time, the slide plate 33 will detach from the circular hole 22 and put the circular hole 22 in an open state, and the slide plate 33 that is not in contact with the workpiece will seal the circular hole 22. Because the total air flow inside the first connecting plate 15 and the second connecting plate 16 remains unchanged, the air flow at the circular hole 22 where the workpiece contacts will become larger, further increasing the device's adsorption effect on the workpiece.

[0029] See also Figure 5 As shown, a water bag 4 is fixedly connected to the inner wall of the suction cup 23; the water bag 4 is located on the top of the workbench 1; when the workpiece comes into contact with the suction cup 23, it will also come into contact with the water bag 4. After being squeezed, the water bag 4 will rupture and the water inside will flow out. The water will moisten the suction cup 23 and the surface of the workpiece, reduce the gap between the suction cup 23 and the workpiece, and further enhance the adsorption effect of the suction cup 23 on the workpiece.

[0030] See also Figure 5As shown, a tool 5 is symmetrically fixed to the middle of the slide bar 34; the water bag 4 is located between the tool 5 and the suction cup 23; when the slide bar 34 moves, it will move with the tool 5, and when the tool 5 moves, it will come into contact with the water bag 4 and cut the surface of the water bag 4, ensuring that the water bag 4 can be stably broken when the workpiece squeezes the water bag 4, so as to achieve the wetting effect on the suction cup 23 and the surface of the workpiece.

[0031] See also Figure 4 As shown, a plurality of bristles 6 are fixedly connected to the bottom of the first connecting plate 15 and the second connecting plate 16; the bristles 6 are arranged in an array; when the first connecting plate 15 and the second connecting plate 16 move, the bristles 6 will also move together, and when the bristles 6 move, they will come into contact with the surface of the workbench 1 and clean the surface of the workbench 1, thereby reducing impurities attached to the surface of the workbench 1 and improving the convenience of the device for cleaning the workbench 1.

[0032] See also Figure 1 As shown, a plurality of table legs 7 are fixedly connected to the bottom of the workbench 1; universal wheels 72 are fixedly connected to the bottom of the table legs 7; when the position of the workbench 1 needs to be adjusted, the staff can turn on the universal wheels 72 and push the workbench 1, at which time the universal wheels 72 will rub against the ground and start to rotate, thereby improving the convenience of moving the device.

[0033] Working principle: the staff puts the workpiece on the top of the fixed groove 17 and then starts the device. After the device is started, the motor 12 will be started. After the motor 12 is started, the first gear 13 will rotate. When the first gear 13 rotates, it will mesh with the second gear 14 and cause the second gear 14 to rotate. When the second gear 14 rotates, it will drive the rotating shaft 18 to rotate together. When the rotating shaft 18 rotates, it will drive the first connecting plate 15 and the second connecting plate 16 to move together and make them close to the workpiece. At this time, a pair of first connecting plates 15 will approach the workpiece at the same time, and the second connecting plate 16 will contact the workpiece when it moves. Because the second connecting plate 16 is inclined, the workpiece will move along the second connecting plate 16 when it contacts the second connecting plate 16. The surface of the connecting plate 16 moves, so that the position of the workpiece will be adjusted. When the first connecting plate 15 contacts the surface of the workpiece, the workpiece will be fixed under the squeezing action of the first connecting plate 15 and the second connecting plate 16. Finally, the staff can operate the cutting machine to cut the workpiece. When the device is started, the staff can connect the air pipe 2 to an air pump so that the air pump can pump air into the air pipe 2. The air flow will enter the inside of the circular hole 22 from the outside, and then pass through the first connecting plate 15 and the second connecting plate 16, and then enter the inside of the air pipe 2. At this time, a negative pressure state will be formed at the circular hole 22. After the workpiece contacts the first connecting plate 15 and the second connecting plate 16, it will also contact the suction cup 23. Because the circular hole 22 is in a negative pressure state, After the workpiece contacts the suction cup 23, it will be sucked and fixed by the suction cup 23, increasing the contact area between the device and the workpiece; when the workpiece contacts the suction cup 23, it will also contact the slide bar 34. After the workpiece squeezes the slide bar 34, the slide bar 34 will move with the slide plate 33 and compress the spring 32. At this time, the slide plate 33 will be separated from the circular hole 22 and the circular hole 22 will be in an open state, and the slide plate 33 that is not in contact with the workpiece will seal the circular hole 22. Because the total air flow inside the first connecting plate 15 and the second connecting plate 16 remains unchanged, the air flow at the circular hole 22 where the workpiece contacts will increase; when the water bag 4 is squeezed, it will rupture, causing the water inside to flow out, and the water will press the suction cup 23 and the surface of the workpiece. When the workpiece is wetted, the gap between the suction cup 23 and the workpiece is reduced; when the slide bar 34 moves, it will move with the tool 5, and when the tool 5 moves, it will come into contact with the water bag 4 and cut the surface of the water bag 4, ensuring that the water bag 4 can be stably broken when the workpiece squeezes the water bag 4; when the first connecting plate 15 and the second connecting plate 16 move, they will also move with the bristles 6, and when the bristles 6 move, they will come into contact with the surface of the workbench 1 and clean the surface of the workbench 1, reducing impurities attached to the surface of the workbench 1; when the position of the workbench 1 needs to be adjusted, the staff can turn on the universal wheel 72 and push the workbench 1, at this time the universal wheel 72 will rub against the ground and start to rotate, improving the convenience of the device when moving.
