The rear part of the upper mold 8 is in contact with the upper front end of the main body 1. The rear part of the positioning seat 7 and the rear part of the lower mold 10 are fixedly connected to the front end outside of the main body 1. The positioning seat 7 is restricted by the main body 1 so that the upper mold 8 can only slide vertically, and the lower mold 10 is fixed by the main body 1 to keep the position unchanged. The lower right end of the bending assembly contacts with a positioning device 5, and the positioning device 5 can position the hexagonal bar that slides in so that it can slide to the upper end of the lower mold 10. The rear part of the positioning device 5 is fixedly connected to the front end outside of the main body 1, and the main body 1 keeps the positioning device 5 relatively fixed. The internal sliding connection of the positioning device 5 is a rod 6, and the rod 6 can be cut by a tool for stamping and bending.

[0032] Reference Figure 1-Figure 3The left end of the main body 1 is internally slidably connected with a sliding block 4, and the sliding block 4 can drive the block 13 to slide quickly to adjust the length of the hexagonal rod, and the adjustment method is simple and convenient. The left end of the sliding block 4 is internally threaded with a bolt 14, and the rotation of the bolt 14 can make the stopper 13 fine-tune the position more accurately, thereby increasing the accuracy of the limit. The front end of the bolt 14 is fixedly connected with a block 13, and the block 13 can block the length of the hexagonal rod to be fixed. The right end of the sliding block 4 is internally slidably connected with a clamping block 15, and the clamping block 15 can fix the sliding block 4 at different positions inside the main body 1. The clamping block 15 is provided with two groups, and the two groups of clamping blocks 15 are elastically connected by a spring 18. The spring 18 can squeeze the clamping block 15 to fix it inside the main body 1 to keep the sliding block 4 relatively fixed, and the outside of the clamping block 15 The sliding connection is inside the front end of the main body 1, and the two ends of the spring 18 are respectively fixedly connected to the outside of the side ends of the two groups of card blocks 15. A square groove is provided in the middle of the card block 15, so that the inclined surface block 17 can slide in. The side end of the card block 15 is slidably connected with the inclined surface block 17. The inclined surface block 17 is U-shaped and the left end is an inclined surface. The inclined surface extrusion can make the card block 15 slide into the interior of the sliding block 4 to release the limit and slide to adjust the position. The front end side of the inclined surface block 17 is fixedly connected with a sliding handle 16, and the sliding handle 16 can drive the inclined surface block 17 to slide for extrusion and facilitate the sliding of the sliding block 4.

Under the rotation of the power device 9, the upper die 8 slides up so that the product can slide down. When the block 15 inside the sliding block 4 is worn or the spring 18 fails, the positioning rod 12 can be slid out of the hinged rod 11 by sliding up, and then the stop block 3 is rotated relative to the hinged rod 11 until it no longer closes the side end of the main body 1. Then, the sliding handle 16 is slid to drive the inclined block 17 to slide and squeeze the block 15. The block 15 slides into the sliding block 4 to squeeze the spring 18 and then slides it out of the main body 1. The block 15 and the spring 18 are replaced and then slid back to their original positions. The stop block 3 is rotated back to its original position, and the positioning rod 12 is slid into the hinged rod 11 and kept fixed.
