In order to fix the stable fit between the thin elbow and the bending head, the button is released and the insert block is inserted into the L-connecting rod. At this time, the thin elbow and the bending head can be kept stably fit. By setting the adjustment device, when performing bending operations on the bending machine, it is easy to make corresponding adjustments according to the requirements of different types of materials or workpieces.

[0025] The effect achieved by the above components is that by providing the thin elbow 51 , bending can be performed according to different types of materials.
[0026] Specifically, the slider 52 is slidably connected to the inner wall of the slide groove 53 , and grooves 54 are provided on both sides of the slider 52 , and the grooves 54 are slidably connected to the surface of the bending head 4 .
[0027] The effect achieved by the above components is: by providing the groove 54 and cooperating with the bending head 4, the slider 52 is prevented from being separated from the wall when sliding on the inner wall of the sliding groove 53.
[0028] Specifically, the inner wall of the slider 52 is rotatably connected to a rotating rod 55 , a surface of the rotating rod 55 is fixedly connected to an L-shaped connecting rod 56 , and one end of the L-shaped connecting rod 56 away from the rotating rod 55 is fixedly connected to a column block 57 .
[0029] The effect achieved by the above components is that, by arranging the cooperation of the L-type connecting rod 56 and the column block 57 , it is convenient for the rotating rod 55 to drive the thin elbow 51 to rotate open when rotating.
[0030] Specifically, the column block 57 is fixedly connected to the surface of the thin elbow 51 , and a pressing spring 58 is fixedly connected to the inner wall of the bending head 4 .
[0031] The effect achieved by the above components is that by providing the pressing spring 58 , it is possible to provide a stable preparation for the thin elbow 51 and the bending head 4 .
[0032] Specifically, an insert block 59 is fixedly connected to the surface of the pressing spring 58 . The insert block 59 is inserted into the inner wall of the L-shaped connecting rod 56 . A pressing block 510 is fixedly connected to the surface of the insert block 59 .
[0033] The effect achieved by the above components is that the insertion block 59 is provided to facilitate the fixing of the bending head 4 and the thin elbow 51 .
[0034] Specifically, a fixing block 511 is fixedly connected to the inner wall of the bending machine body 1. There are two fixing blocks 511 and they are symmetrically arranged.

By setting the adjustment device 5, when performing bending operations on the bending machine, it is easy to make corresponding adjustments according to the requirements of different types of materials or workpieces. In view of the fact that the traditional bending head 4 design is often fixed, in order to adapt to diverse bending requirements, this improvement enhances the flexibility and ease of operation of the equipment.
