[0028] Further, a clamping groove 8 is opened in the middle of the rotating head 21, a threaded hole is opened through one side of the upper part of the clamping groove 8, and a locking bolt 1 7 is installed in the threaded hole. The workpiece to be processed can be effectively locked through the locking bolt 1 7 to ensure the processing stability.

[0029] Further, the mounting frame 15 is in an inverted "Y" shape, one end of its bifurcated section is rotatably installed on the rotating seat 11 with a torsion spring, and the other end is connected to a connecting rod 14. The two ends of the connecting rod 14 are respectively installed in the arc-shaped notch opened in the middle of the arc-shaped guiding block 12 in a limited manner.

[0030] Further, one end of the connecting rod 14 extends out of the arc-shaped guiding block 12 and is threadedly connected with a locking cylinder 13. The locking cylinder 13 is used to lock the mounting bracket 15, so as to lock the rotation angle of the mounting bracket 15.

[0031] Further, a handle 9 is installed on one side of the mounting bracket 15.

[0032] Further, a threaded hole is formed in the middle of the moving plate 3, and a second locking bolt 10 is installed in the threaded hole. The bottom end of the second locking bolt 10 is limited to slide in the sliding groove 101.

[0038] In the present utility model, the fastener to be processed is clamped and locked into the rotating head 21, and the input shaft 22 is driven by a driving mechanism to drive the fastener to rotate. At this time, the driving motor 6 drives the grinding roller 4 to grind the surface of the fastener. Under the opposite rotation of the fastener and the grinding roller 4, the thread section of the fastener can be effectively ground. The process is convenient to operate and has a high grinding efficiency, which can effectively improve the processing quality.

[0039] Meanwhile, through components such as the moving plate 3, the handle 9, and the locking cylinder 13, the functions of adjusting the horizontal position and the grinding angle of the grinding roller 4 can be effectively realized to meet different processing requirements.
