There are various implementation manners of the above-mentioned driving device, which are not limited here, as long as the two support rods can be driven to move up and down and move horizontally.

As shown in FIG. 1 and FIG. 3 , further, the lower die is provided with a discharge hopper 120 corresponding to the trimming and punching stations. It can be observed from Fig. 3 that a discharge hopper is respectively provided on both sides of the lower die corresponding to the trimming and punching stations, which are used to remove the waste material from the cut-off side panel of the backrest.

Please refer to FIG. 5 and FIG. 7 , further, a plurality of sliding blocks 61 are provided at the corresponding punching and side punching stations of the lower die, and each sliding block is respectively provided with a punch 619 for side punching. An inclined surface 610 is respectively provided on the outer side of each sliding block; a pushing block 62 is respectively provided at the bottom of the upper die corresponding to each sliding block, and an inclined surface 620 is respectively provided on the inner side of each pushing block. It is equal to the inclination angle of the inclined surface on the outer side of the corresponding slider. That is, when the upper die is pressed down, the inclined surface of each push block presses the inclined surface of the corresponding slider and generates a horizontal component force, so that the slider moves horizontally to realize side punching.

Further, each sliding block 61 is respectively disposed in a sliding block mounting seat 60, and each sliding block mounting seat is respectively connected with the lower die bolt. That is, the sliding block can slide horizontally relative to the sliding block mounting seat. In practical application, the sliding block mounting seat is provided with a spring (not visible from the perspective of the attached drawing).
