Several guide plates with the same spacing are arranged on the arc surface inside the transmission wheel 9, and a protruding block 10 is installed on the arc surface of the transmission wheel 9.

[0021] like Figure 1 and Figure 2 As shown, an inclined rectangular groove 11 is provided on the long vertical surface of the outside of the L-shaped mounting plate 3, and a driving motor 12 is provided inside the rectangular groove 11, a moving block 13 is penetrated by the rotating shaft of the driving motor 12, a thread is provided on the rotating shaft of the driving motor 12, and a cylindrical hole is provided at the intersection of the rotating shaft and the moving block 13, and a thread groove is provided on the arc surface inside the cylindrical hole, the thread groove and the thread on the rotating shaft are in a meshing relationship, and an L-shaped guide rod 14 is provided on the vertical surface of the moving block 13 away from the rectangular groove 11, and the L-shaped guide rod 14 is also a telescopic sleeve rod.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, a notch 15 is further provided at the long vertical surface of the L-shaped mounting plate 3, a transmission rod 16 is installed on the rod body of the round rod 4 at the lower end of the L-shaped mounting plate 3, and a groove is provided at the end point of the transmission rod 16 away from the round rod 4, and a rotating rod 17 is provided through the inside of the groove, and a handle 18 is provided on the rod body of the rotating rod 17 inside the groove.

[0023] like Figure 2 and Figure 3 As shown, cylindrical rockers 19 are provided on the lower surface of the transmission rod 16 and the lower surface inside the L-shaped mounting plate 3. The lengths of the pair of cylindrical rockers 19 are different, but the connecting sleeves 20 are at the same level. The rod bodies of the pair of cylindrical rockers 19 are provided with connecting sleeves 20, and the connecting sleeves 20 and the cylindrical rockers 19 are in a rotational connection relationship. A telescopic sleeve rod 21 is installed between the pair of connecting sleeves 20, and a memory spring 22 is provided inside the telescopic sleeve rod 21.

[0024] Working principle: When the device is working, first place the annular member on the L-shaped mounting plate 3, and then rotate the transmission rod 16 through the handle 18. At this time, the handle 19 is in a horizontal state. Because the transmission rod 16 is connected to the rod body of the round rod 4, and the transmission rod 16 is in a fixed relationship, when the transmission rod 16 rotates, the round rod 4 will also be driven to rotate, because a pair of mounting sleeves 5 are provided on the rod body at the upper end of the round rod 4, and the pair of mounting sleeves 5 are sandwiched between the arc plate 6, and the arc surface outside the arc plate 6 is provided with mounting strips 7, and several rectangular blocks with the same spacing are installed on the mounting strips 7.

A transmission wheel 9 is penetrated by the rod body at the upper end of the rotating cylinder 8. The transmission wheel 9 and the rotating cylinder 8 are in a fixed relationship. Several guide plates with the same spacing are arranged on the arc surface inside the transmission wheel 9, and a protruding block 10 is installed on the arc surface of the transmission wheel 9. The guide plates arranged inside the transmission wheel 9 and the rectangular blocks arranged on the arc surface of the mounting strip 7 are in a meshing relationship. Therefore, when the round rod 4 rotates, the arc plate 6 will drive the transmission wheel 9 to rotate, thereby positioning the circular ring part. After the circular ring part is positioned, the driving motor 12 is started, so that the rotating shaft on the driving motor 12 drives the moving block 13 to move, so that the L-shaped guide rod 14 and the transmission rod 16 are released, thereby locking it, and then processing can be carried out.
