A second end plate 3119 is fixedly connected to one end of the second insert block 3118. A third threaded hole 31110 is opened at one end of the movable mounting base 3116. A fourth fastening bolt 31111 is threadedly connected to the inner side of the third threaded hole 31110. A through hole that matches the fourth fastening bolt 31111 is opened inside the second end plate 3119. A fastening top plate 31112 is fixedly connected to the top of the second insert block 3118. An arc-shaped groove is opened on the side of the fastening top plate 31112 away from the connecting limit sleeve 3115, corresponding to the position of the positioning groove 25.

[0050] The drive rod 3113 is deflected to drive the rotating end plate 3112, the rotating threaded rod 3111, and the fixed connecting plate 3114 to rotate. The fixed connecting plate 3114 can rotate inside the connecting limit sleeve 3115. At the same time, the rotating threaded rod 3111 can rotate and move between the second threaded block 3104 and the first threaded block 33. This allows the fixed connecting plate 3114, the connecting limit sleeve 3115, the movable mounting base 3116, the second insert block 3118, the second end plate 3119, the fourth fastening bolt 31111, and the fastening top plate 31112 to move and clamp and fix the screw located inside the positioning groove 25.

The replaced first insert block 23 is inserted into the inner side of the first slot 22, so that the precision positioning top block 24 is on top of the fixed base 21, and the first end plate 26 is at the end of the fixed base 21. Finally, the first fastening bolt 28 is inserted into the inside of the first end plate 26 and rotated so that the first fastening bolt 28 can be inserted into the inner side of the first threaded hole 27 for assembly. Then, the fourth fastening bolt 31111 is rotated and disassembled. The second insert block 3118, the second end plate 3119, and the fastening top plate 31112 are disassembled and replaced. The replaced second insert block 3118 is inserted into the inner side of the second slot 3117, so that the second end plate 3119 and the movable mounting base 3116 are in contact with each other. The fourth fastening bolt 31111 is inserted into the second end plate 3119 and rotated to insert into the inner side of the third threaded hole 31110, thus achieving a stable connection. Then, the screw is placed inside the positioning groove 25 for precise positioning. Subsequently, the drive rod 3113 is deflected, causing the rotating end plate 3112, the rotating threaded rod 3111, and the fixed connecting plate 3114 to rotate. The fixed connecting plate 3114 can connect to the limiting sleeve 3. The internal rotation of 115 allows the rotating threaded rod 3111 to rotate and move between the second threaded block 3104 and the first threaded block 33, thereby enabling the movement of the fixed connecting plate 3114, the connecting limit sleeve 3115, the movable mounting base 3116, the second insert block 3118, the second end plate 3119, the fourth fastening bolt 31111, and the fastening top plate 31112, and clamping and fixing the screw located inside the positioning groove 25.
