At this time, the first ratchet wheel cooperates with the first ratchet pawl, and the top rotating shaft 21 rotates. The two top sliders 22 move synchronously in opposite directions. When the top sliders 22 drive the threaded blocks 241 to move away from each other, the threaded tube 24 rotates. Under the meshing action of the driving gear 242 and the transmission gear 251, the transmission shaft 25 rotates, so that the rack 281 is disengaged from the fixed gear 262. Then the driving member 291 rotates in reverse, the second ratchet wheel cooperates with the second ratchet pawl, so that the bottom rotating shaft 26 rotates. Under the cooperation of the bottom slider 261 and the connecting rod 271, the pushing plate 27 moves, thereby changing the length of the part of the sheet metal part located on the top surface of the base 1. Then the driving member 291 rotates forward to fix the sheet metal part by the fixing plate 23. Then the telescopic member 15 extends, driving the bending plate 14 to rotate and complete the bending.
