Specifically, referring to fig. 1-5, both sides of the plate 51 to be bent can be bent, i.e. the bending modes can be divided into front bending and back bending. The side plate 52 is bent in front when facing upwards by taking the table top 11 as a reference, the side plate 52 penetrates through the groove 71 on the positioning mechanism 2, the to-be-bent plate 51 penetrates through the bending channel 4, one end of the to-be-bent plate is arranged on the placing position on the workbench 1, and the other end of the to-be-bent plate is arranged on the bearing surface 6. With the bending shaft 50 as the center, under the driving of the bending mechanism 3, one end of the to-be-bent plate 51 on the bearing surface 6 tilts upward with the bending shaft 50 as the center, so that the to-be-bent plate 51 is bent.
