[0020] like Figure 1 and Figure 2The adjusting mechanism includes a moving block 8, a threaded rod 9 and a moving seat 10. A transversely arranged moving groove is opened on the left side of the upper end of the base plate 1. The moving block 8 is slidably arranged in the moving groove. The moving seat 10 is fixedly arranged on the upper end of the moving block 8. The driven three-jaw chuck 4 is rotatably arranged on the right side of the moving seat 10 through a bearing seat. The threaded rod 9 is rotatably arranged in the moving groove through a bearing and is threadedly connected to the moving block 8. The left end of the threaded rod 9 extends to the outside of the base plate 1 and is fixedly connected with a handwheel 11. A clamping mechanism for fixing the threaded rod 9 is arranged on the left side of the base plate 1. By rotating the handwheel 11, the threaded rod 9 can be driven to rotate. The rotation of the threaded rod 9 can drive the moving block 8 to move in the moving groove. The moving block 8 drives the moving seat 10 to move laterally. The moving seat 10 drives the driven three-jaw chuck 4 to move laterally, thereby being able to fix and support the ends of rods of different lengths.

[0025] The working principle of the utility model is as follows: when threading a rod, one end of the rod is inserted into the active three-jaw chuck 3 and fixed, and then the driven three-jaw chuck 4 is driven to move by the adjusting mechanism, so that the other end of the rod is inserted into the driven three-jaw chuck 4 and fixed, and at the same time, the L-shaped pull plate 5 is driven to move by the cylinder 7, so that the upper side of the horizontal part of the L-shaped pull plate 5 is abutted against the lower rod wall of the rod, and then the threaded rod 9 is threaded. While threading, the cylinder 7 and the L-shaped pull plate 5 are driven to move horizontally by the moving mechanism, so that the L-shaped pull plate 5 moves synchronously with the turning tool until the thread processing is completed. The upper device can fix and support the two ends of the rod to prevent the rod from swinging when it rotates, and at the same time can support the thread processing position of the rod to prevent the turning tool from bending the rod, thereby improving the processing quality and facilitating people's use.
