The overall structure is simple and the operation is convenient and fast.

[0028] In another embodiment, as Figure 4 shown, the connection and positioning mechanism 6 includes a fixed mounting frame 13. An active connecting rod 14 is movably connected inside the fixed mounting frame 13. One end of the active connecting rod 14 is fixedly connected with a force-bearing mounting plate 15. Connection and positioning insertion rods 16 are symmetrically arranged on one side of the force-bearing mounting plate 15 away from the active connecting rod 14. The end of the active connecting rod 14 away from the force-bearing mounting plate 15 is fixedly connected with a connection mounting arm 18. A first force spring 17 is fixedly connected between the inner side of the fixed mounting frame 13 and one side of the force-bearing mounting plate 15. First fixed connecting arms 19 are arranged at both ends of the connection mounting arm 18. A fixed through groove 20 is opened at one end of the first fixed connecting arm 19 away from the connection mounting arm 18.

[0029] It is convenient to insert the L-shaped metal rod into the inside of the fixed through groove 20 and pull it, driving the first fixed connecting arm 19, the connection mounting arm 18, the active connecting rod 14, the force-bearing mounting plate 15 and the connection and positioning insertion rod 16 to move, compressing the first force spring 17, so that the connection and positioning insertion rod 16 can be pulled out from the inside of the fixed positioning hole 5, so as to quickly adjust the whole connection and positioning mechanism 6, and the operation is convenient.

[0030] In another embodiment, as Figure 4 shown, the outer surface of the connection and positioning insertion rod 16 slides and fits with the inside of the fixed through hole 7, and the outer surface of the connection and positioning insertion rod 16 slides and fits with the inside of the fixed positioning hole 5.

[0031] It is convenient for the connection and positioning insertion rod 16 to stably move inside the fixed positioning hole 5 and the fixed through hole 7, and the operation is convenient.

[0032] In another embodiment, as Figure 2 and Figure 3 shown, the cross-sectional shapes of the fixed connection plug 4 and the fixed card slot 2 are T-shaped, and the outer surface of the fixed connection plug 4 slides and fits with the inside of the fixed card slot 2.

[0033] The insertion block 4 is convenient for fixed connection and can be stably inserted into the inner side of the fixed card slot 2, which is convenient to operate.

[0034] In another embodiment, as Figure 3 shown, the inside of the boring tool 10 slides and fits with the outer surface of the threaded rod 9 and the inner side of the fixed groove 8.

[0035] The boring tool 10 is convenient for being stably stuck inside the fixed groove 8 and sleeved on the outer surface of the threaded rod 9, which is convenient to operate.

[0036] In another embodiment, as Figure 5 shown, the locking and limiting mechanism 12 includes a threaded sleeve 21. A second fixed connection arm 22 is fixedly connected to the top of the threaded sleeve 21. A connection sleeve block 23 is fixedly connected to one end of the top of the second fixed connection arm 22 away from the threaded sleeve 21. An active limit insertion rod 24 is movably connected inside the connection sleeve block 23 and the second fixed connection arm 22. A force-bearing sleeve ring 25 is fixedly sleeved on the outer surface of the active limit insertion rod 24. A second force-bearing spring 26 is fixedly connected between the top of the force-bearing sleeve ring 25 and the top of the connection sleeve block 23. A connection pull ring 27 is fixedly connected to the top of the active limit insertion rod 24.

[0037] Pull the connection pull ring 27 upward to drive the active limit insertion rod 24 and the force-bearing sleeve ring 25 to move, compress the second force-bearing spring 26, and then rotate the second fixed connection arm 22 and the threaded sleeve 21 so that the threaded sleeve 21 rotates and moves downward on the outer surface of the threaded rod 9, enabling the threaded sleeve 21 to press down and fix the boring tool 10. After locking the boring tool 10, the connection pull ring 27 can be released. When the force-bearing sleeve ring 25 is affected by the second force-bearing spring 26, it drives the active limit insertion rod 24 to move downward, enabling the bottom end of the active limit insertion rod 24 to insert into the inner side of the fixed limit hole 11, thereby achieving connection limitation, which is convenient to operate.

[0038] In another embodiment, as Figure 3 and Figure 5 shown, the outer surface of the bottom end of the active limit insertion rod 24 slides and fits with the inner side of the fixed limit hole 11.

[0039] It is convenient for the bottom end of the active limit insertion rod 24 to be stably inserted into the inner side of the fixed limit hole 11, and the operation is convenient and fast.

Then insert the fixed connection plug 4 into the inside of the fixed card slot 2 to install the movable mounting frame 3. Then release the fixing through groove 20. Under the action of the first force-bearing spring 17, the force-bearing installation plate 15 and the connection positioning plug 16 are pushed, so that the connection positioning plug 16 can be stably inserted into the inside of the fixed positioning hole 5 to install and fix the movable mounting frame 3. Then place the boring tool 10 in the inside of the fixed groove 8 and sleeved on the outer surface of the threaded rod 9. Then pull the connection pull ring 27 upward, driving the movable limit plug 24 and the force-bearing collar 25 to move, compressing the second force-bearing spring 26. Then rotate the second fixed connection arm 22 and the threaded sleeve 21, so that the threaded sleeve 21 rotates and moves downward on the outer surface of the threaded rod 9, so that the threaded sleeve 21 presses down and fixes the boring tool 10. After locking the boring tool 10, the connection pull ring 27 can be released. When the force-bearing collar 25 is affected by the second force-bearing spring 26, it drives the movable limit plug 24 to move downward, so that the bottom end of the movable limit plug 24 can be inserted into the inside of the fixed limit hole 11 for connection restriction. The overall structure is simple and the operation is convenient.
