[0030] Reference Figure 1 and Figure 2 As shown, a slide groove 6 is symmetrically opened in the middle of the workbench 1; a collection box 62 is slidably connected inside the slide groove 6; when the device processes the workpiece, debris will be generated, and the staff can collect the impurities on the surface of the workbench 1 and put them into the collection box 62; by setting the collection box 62, the staff can concentrate the impurities on the surface of the workbench 1 inside the collection box 62, reduce the impurities remaining on the surface of the workbench 1, and improve the convenience of the device to clean the surface of the workbench 1.

[0033] Working principle: After placing the workpiece on the top of the workbench 1, the workpiece can be processed by the processing mechanism 12. When the size of the workpiece is too large, one end of the workpiece can be placed on the top of the workbench 1, and then the slide plate 15 is pulled to drive the slide plate 15 to start moving along the telescopic rod 14. When the slide plate 15 moves, it will drive the telescopic rod 14 to move together and put the telescopic rod 14 in a stretched state. When the slide plate 15 is adjusted to a suitable position, the other end of the workpiece can be placed on the top of the slide plate 15. After the workpiece is placed on the top of the slide plate 15, it will contact and squeeze the first elastic cloth 16, driving the shape of the first elastic cloth 16 to bend and fit tightly to the surface of the workpiece. At this time, the processing mechanism 12 can be started to process the workpiece. When the workpiece is pressed against the first elastic cloth 16, the workpiece will continue to approach the slide plate 15, and will come into contact with the suction cup 24 during the approaching process. The workpiece will press the suction cup 24 and expel the air in the suction cup 24. Under the action of atmospheric pressure, the suction cup 24 will adsorb the surface of the workpiece, and the workpiece will continue to move and come into contact with the cross plate 23. After the cross plate 23 is subjected to the pressure of the workpiece, it will move and transfer the pressure to the first spring 22 and compress the first spring 22. After being compressed, the first spring 22 will release its elastic potential energy and make the cross plate 23 squeeze the surface of the workpiece, and the second elastic cloth 25 will move together with the cross plate 23, increasing the pressure between the device and the workpiece. When the suction cup 24 is squeezed by the workpiece, the elastic rod 3 will also come into contact with the workpiece. When the elastic rod 3 is squeezed by the workpiece, part of it will bend and adhere to the surface of the workpiece, while the other part will enter the gap on the surface of the workpiece, thereby increasing the contact area between the device and the workpiece. When the workpiece squeezes the suction cup 24, it will continue to approach the cross plate 23. During the process, the workpiece will come into contact with the pressure ring 42 and squeeze the pressure ring 42. After being squeezed, the pressure ring 42 will transfer the pressure to the second spring 4. After being squeezed, the second spring 4 will shrink and release its elastic potential energy, thereby driving the pressure ring 42 to squeeze the middle part of the suction cup 24, thereby reducing the air entering the suction cup 24. When the workpiece squeezes the second elastic cloth 25, the workpiece will also come into contact with the rubber pad 5. Contact occurs, because the surface of the rubber pad 5 is a wavy structure, the rubber pad 5 will have a larger contact area with the surface of the workpiece, and the friction coefficient of the surface of the rubber pad 5 is larger, so that the friction between the device and the workpiece will also increase; when the device processes the workpiece, debris will be generated, and the staff can collect the impurities on the surface of the workbench 1 and put them into the collection box 62; when there are impurities on the surface of the workbench 1, the collection box 62 can be slid to the corresponding position, and then the scraper 73 can be pulled to drive the slide bar 7 to slide along the collection box 62, and when the slide bar 7 slides, the third spring 72 will be in a compressed state, and when the scraper 73 moves, it will rub against 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;When the slide bar 7 slides, the bristles 8 will also slide along with the slide bar 7. When the bristles 8 move, they will rub against the surface of the workbench 1 and clean the surface of the workbench 1, thereby reducing dust on the surface of the workbench 1. ;

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
