[0024] Furthermore; when the fasteners in the polishing container 40 are placed, the output rod 15 will continue to move forward, causing the triangular block 19 to contact the guide block 13, causing the toggle rod 18 to slide backward to compress the spring 17, and when the toggle rod 18 slides backward, it is separated from the toggle plate 34. At the same time, the rebound force of the spring 27 and the spring 33 causes the baffle plate 1 22 and the baffle plate 2 30 to be reset. After the reset is completed, the polishing container 40 continues to rotate so that it is placed on the magnetic polishing device 41 for polishing.

[0025] Furthermore; when the fasteners in the polishing container 40 are polished, continue to rotate the rotating rod 10 to make the gear 2 52 mesh with the tooth block 44. The meshed polishing container 40 will drive the polished fasteners to move to the top of the discharge box 59, so that the gear 2 52 rotates to drive the circular column 2 51 and the connecting block 2 50 to rotate. When the connecting block 2 50 rotates, the rotating shaft 2 49 drives the swing rod 48 to rotate and swing up and down. When the swing rod 48 rotates and swings up and down, it will drive the connecting plate 47 and the circular column 1 46 to rotate, and the polishing container 40 is rotated 360 degrees through the circular column 1 46. During the rotation of the polishing container 40, the polished fasteners inside are inverted in the discharge box 59 for collection.

[0026] Then; when the polished fasteners and cleaning agent enter the lower material box 59, the fasteners and the cleaning agent are separated by the separation plate 60, and then the cleaning agent will fall downward and pass through the filter 61 to filter the abrasive produced after polishing, and then the filtered cleaning agent will flow to the bottom of the inner part of the pull handle lower material box 59. When adding fasteners to the polishing container 40, the cleaning agent in the water tank 54 can be drawn by the water pump 55 and transported to the polishing container 40 through the connecting pipe 56 and the nozzle 57. At the same time, the filtered cleaning agent in the lower material box 59 can be transmitted to the water tank 54 through the L-shaped connecting pipe 58 for recycling, thereby reducing resource waste.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
