[0026] Specifically, the base plate 1 can fix the vertical plate 2, and the base plate 1 can fix the motor 12. By starting the motor 12, the worm 13 can be rotated, and the worm wheel 4 can be rotated to drive the rotating column 3 to rotate on the inner wall of the vertical plate 2 and drive the locking plate 5 and the connecting bar 6 to rotate, thereby causing the round pin 7 to rotate. When the round pin 7 rotates, it will slide into the inner wall of the groove wheel 9, and the groove wheel 9 can drive the U-shaped frame 10 to rotate intermittently through the rotating column 2 8.

[0027] Reference Figure 1 、 Figure 4 and Figure 5 , a card slot 21 is provided on the inner wall of the grinding disc 20; the inner sliding connection of the round block 19 is provided with a sliding post 22, one end of the sliding post 22 is fixedly connected to the round block 23, and the outer wall of the round block 23 is slidably connected to the inner wall of the round block 19; the end of the round block 23 away from the sliding post 22 is fixedly connected to one end of the spring 27, and the other end of the spring 27 is fixedly connected to the inner wall of the round block 19; the end of the round block 23 away from the sliding post 22 is fixedly connected to the inclined frame 24, and the inner wall of the inclined frame 24 is slidably connected with a card post 25; the outer wall of the card post 25 is fixedly connected to the limiting post 29, and the outer wall of the limiting post 29 is slidably connected to the outer wall of the inclined frame 24, the outer wall of the card post 25 is fixedly connected to the limiting post 1 26, and the outer wall of the limiting post 1 26 is slidably connected to the inner wall of the inclined frame 24;

[0031] Working principle: When using the grinder, the shaft-like metal workpiece to be ground is fixed by rotating the threaded column 11 and the fixed block 14, and then the motor 2 28 is started to drive the round block 19 to drive the grinding disc 20 to grind the shaft-like metal workpiece.

The turning of the shaft-like metal workpiece is completed with a certain degree of accuracy, so as to achieve the effect of turning the shaft-like metal workpiece after the processing is completed, thereby reducing the time of repeated operations, realizing continuous operation and improving the processing efficiency. When it is necessary to replace the grinding cutter disc 20, pressing the sliding column 22 causes the round block 23 to slide on the inner wall of the round block 19 and drives the inclined frame 24 to move, and at the same time causes the spring 27 to be forced to shrink.
