A limited bearing seat is installed on one side of the mounting plate 306, and the bearing seat is rotatably connected to the threaded sleeve 309. The movement of the mounting plate 306 can drive the threaded sleeve 309 to move. The rotation of the threaded rod 304 is used to drive the mounting plate 306 to move vertically to change the distance between the threaded sleeve 309 and the cover plate 2. The rapid tooling of the trepanning tool body 1 can be completed by unfolding the threaded sleeve 309. A docking ring 5 is welded to the bottom of the trepanning tool body 1, and a rubber pad is provided on the inside of the docking ring 5. One end of the boring bar can be inserted into the docking ring 5 for docking and fixing, and the rubber pad provides a higher friction force to ensure the stability of the boring bar and the docking ring 5 after docking.

[0029] Example 2: Please refer to Figure 1-5, On the basis of the above-mentioned embodiment, the fixed structure 3 of this embodiment includes a main gear 301 rotatably connected to the inside of the nesting tooling body 1. The center position of the nesting tooling body 1 is annular. The main gear 301 is rotatably connected to the outside of the central ring of the nesting tooling body 1 and is rotatably connected to the transmission rod 303 inside the nesting tooling body 1. The transmission rod 303 is made of stainless steel to avoid the transmission rod 303 from breaking. A transmission gear 302 is fixed at one end of the transmission rod 303. A cross slot is provided above the transmission gear 302 to facilitate the staff to use a hand drill to drive the transmission gear 302 to rotate. A first gear 305 is fixed at one end of the threaded rod 304. The rotation of the first gear 305 can drive the threaded rod 304 to rotate. The connecting rod 307 under the cover plate 2 is rotatably connected. A second gear 308 is fixed at one end of the connecting rod 307. The rotation of the second gear 308 can drive the connecting rod 307 to rotate. The main gear 301 is meshed with the transmission gear 302, and the transmission gear 302 rotates. The main gear 301 is driven to rotate, the main gear 301 is meshed with the first gear 305, the main gear 301 is driven to rotate by the first gear 305, the main gear 301 is meshed with the second gear 308, the main gear 301 is driven to rotate by the second gear 308, the second gear 308 is driven to rotate by the connecting rod 307, the threaded sleeve 309 is slidably connected to the connecting rod 307, the connecting rod 307 is driven to rotate by the threaded sleeve 309, and the threaded sleeve 309 is driven to rotate by the threaded sleeve 309. The threaded sleeve 309 is fixed by being rotated and embedded in the threaded groove of the boring bar. A docking protrusion is provided on the outer side of the bottom of the connecting rod 307, and the docking protrusion is slidably connected to the threaded sleeve 309. The threaded sleeve 309 is limited by the docking protrusion to avoid the situation where the threaded sleeve 309 cannot rotate. There are six groups of threaded sleeves 309, and the bottoms of the six groups of threaded sleeves 309 are conical. The conical shape of the bottom of the threaded sleeve 309 makes it better to embed the threaded sleeve 309 in the threaded groove of the boring bar for fixation.

[0030] Example 3: Please refer to Figure 1-5The cam 402 is provided with a plurality of protrusions 403 on one side of the cover 2, and the plurality of protrusions 403 are provided with protrusions 404 on the other side of the cover 2.

[0031] Working principle: First, when the nesting tool body 1 needs to be installed, align the docking ring 5 with the boring bar of the lathe, then press the nesting tool body 1 so that one end of the boring bar is embedded in the docking ring 5, pull the sliding protrusion of the protective plate 402 to drive the protective plate 402 to move, and the protective plate 402 moves and separates from the magnetic block 403, then insert the drill bit of the hand drill into the cross slot above the transmission gear 302, start the hand drill to drive the transmission gear 302 to rotate, and the rotation of the transmission gear 302 will drive the main gear 301 to rotate;

[0032] Secondly, the rotation of the main gear 301 drives the first gear 305 to rotate, and the rotation of the first gear 305 drives the threaded rod 304 to rotate. Since the threaded rod 304 is threadedly connected to the mounting plate 306, and one side of the mounting plate 306 is in contact with the inner wall of the nesting tool body 1, the rotation of the threaded rod 304 drives the mounting plate 306 to move under the influence of the thread, and the movement of the mounting plate 306 drives the threaded sleeve 309 to move. The threaded sleeve 309 moves and is inserted into the thread groove of the boring bar through the hole at the bottom of the nesting tool body 1.

[0033] Finally, the rotation of the main gear 301 will also drive the second gear 308 to rotate, and the rotation of the second gear 308 will drive the connecting rod 307 to rotate. Since the docking protrusions on both sides of the connecting rod 307 are slidably connected with the threaded sleeve 309, the rotation of the connecting rod 307 will drive the threaded sleeve 309 to rotate. The rotation of the threaded sleeve 309 makes the threads on the outside of the threaded sleeve 309 fit with the thread groove of the boring bar, so that the threaded sleeve 309 is embedded in the thread groove of the boring bar to fix the tooling. The operation is simple and convenient for the staff to install and use the nesting tooling. When the tooling is fixed, pull the protective plate 402 again, and the protective plate 402 moves to fit onto the magnetic block 403 for fixation. The interior of the nesting tooling body 1 is protected by the protective plate 402 to prevent workpiece debris from entering the interior of the nesting tooling body 1.
