The design of the thread structure facilitates the horizontal lateral movement of the positioning plate 96, the outer wall of the rotating rod 93 is threadedly connected with the positioning plate 96, and the rotating rod 93 is plugged into the side away from the fixing plate 91 There is a bearing seat 97, and the bearing seat 97 is set to provide support for the rotating rod 93 when it is rotating or non-rotating. One side of the fixed plate 91 is fixedly connected to one side of the guide rod 92, and the inner wall of the fixed plate 91 is transmission-connected to the outer wall of the rotating rod 93 through a bearing. A corresponding guide hole is opened on the side of the positioning plate 96 corresponding to the guide rod 92. The lower end of the positioning plate 96 contacts the upper end of the workbench 1 and the side of the positioning plate 96 away from the fixed plate 91 contacts the steel bar. The length of the cut steel bar depends on the distance between the blade and the positioning plate 96. The setting of the scale line 10 is convenient for the staff to observe more intuitively and facilitate adjustment.

[0027] Working principle: First, the staff puts the steel bar into the fixing seat 54 and passes it through the fixing frame 55 and the cutting knife groove 3 in sequence, and finally makes one end of the steel bar contact with the positioning plate 96, and then the staff rotates the fixing bolt 53 to loosen the slider 51, and the slider 51 can slide along the slide groove 4, and move the fixing seat 54 to adjust the position of the pressure block 510. After adjusting the position of the fixing seat 54 according to the length of the steel bar, the fixing bolt 53 is locked to position the fixing seat 54, and then the fixing bolt 53 is rotated to make the pressure block 510 and the steel bar contact each other to fix the steel bar. The number of rotations determines the degree of fixation. When performing continuous operation, the fixing bolt 53 can be loosened to allow displacement between the steel bar and the pressure block 510, so that the movable steel bar continues to move forward and contact one side of the positioning plate 96, so that the new end of the steel bar after shearing contacts the positioning plate 96;

[0028] Then, a rotating rod 93 is rotatably installed on one side of the bearing seat 97, a rotating handle 94 is fixedly installed on one end of the rotating rod 93, and a positioning plate 96 is connected to the external thread 95 on the rotating rod 93. A guide rod 92 is fixedly installed on one side of the rotating rod 93 at the top of the workbench 1, and the positioning plate 96 is slidably sleeved on the guide rod 92. A scale line 10 is provided on one side of the positioning plate 96 on the workbench 1. The function of the scale line 10 is to facilitate the adjustment of the length of the steel bar to be cut. The scale line 10 corresponds to the spacing between the fixed plate 91 and the blade. By setting the rotating rod 93, the positioning plate 96 and the scale line 10, the steel bar can be cut at a fixed length. When cutting the steel bars, the rotating rod 93 can be rotated by the rotating handle 94, so that the rotating rod 93 drives the positioning plate 96 to move horizontally along the guide rod 92. Furthermore, the positioning plate 96 is adjusted to a suitable position according to the scale line 10. When cutting the steel bars, it is only necessary to place one end of the steel bar against the positioning plate 96. There is no need to measure each time, which is convenient to operate and improves work efficiency. Finally, the starting cylinder 7 and the cutting component 8 are controlled to cut the steel bars. The above is the working process of the entire device, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
