A tool 18 is fixedly installed between the tool holders 16 on both sides of the same branch. A positioning ring 28 is fixedly installed on the surface of one end of the second rotating shaft 12, and four positioning blocks 29 are fixedly installed on the surface of the positioning ring 28. A concave block 30 is fixedly installed on one side of a mounting plate 10, and a first spring 31 is fixedly installed on the inner side of the concave block 30. A first clamping block 32 is fixedly installed on one end of the first spring 31, and the first clamping block 32 is slidably arranged in the concave block 30. A limiting ring 37 is fixedly installed on the surface of one end of the second rotating shaft 12, and a second mounting groove 33 is opened in a mounting plate 10. One side of the second mounting groove 33 is fixed A second spring 34 is installed, and a second clamping block 35 is fixedly installed at one end of the second spring 34. A pull rod 36 is fixedly installed at one side of the second clamping block 35. The pull rod 36 is slidably set in the second mounting groove 33. By adopting the above technical solution, the pull rod 36 is manually pulled to make the second clamping block 35 slide in the second mounting groove 33 to compress the second spring 34, so that the claw of the second clamping block 35 no longer clamps the groove of the limiting ring 37, and the second motor 14 is controlled to rotate the second rotating shaft 12 on the two mounting plates 10 in the positive direction, driving the cross tool holder 15 to rotate. When the second rotating shaft 12 rotates, the four positioning blocks 29 on the positioning ring 28 at one end rotate simultaneously, and the first clamping block 32 will be pressed due to the abutment of the positioning block 29. The force causes the first spring 31 to contract and slide in the recessed block 30.

[0037] When the tool 18 needs to be replaced, the first motor 7 is controlled to rotate the first rotating shaft 8 to lift the rack 5 upward, and the second motor 14 is controlled by the control panel 19 to rotate the second rotating shaft 12 to switch the direction of the tool changing device 20, and the required tool 18 is switched to the lowermost side, and the pull rod 36 is manually pulled to make the second clamping block 35 slide in the second mounting groove 33 to compress the second spring 34, so that the claw of the second clamping block 35 no longer engages the groove of the limiting ring 37, and the second motor 14 is controlled to rotate the second rotating shaft 12 on the two mounting plates 10 in the positive direction, driving the cross tool holder 15 to rotate, and when the second rotating shaft 12 rotates, the four positioning blocks 29 on the positioning ring 28 at one end rotate at the same time, and the first clamping block 32 will shrink the first spring 31 due to the pressure of the positioning block 29 abutting and slide in the recessed block 30, and when the tool 18 needed is rotated to the required one, the second motor 14 is controlled to rotate in the opposite direction, and at this time the first clamping block 32 will block the positioning block 29 corresponding to the required tool 18 , so that the second rotating shaft 12 cannot continue to rotate in the opposite direction, and the pull rod 36 is released and the second spring 34 rebounds, so that the claw of the second clamping block 35 is re-engaged in the groove of the limit ring 37, so that the cross tool holder 15 on the second rotating shaft 12 is fixed, thereby quickly switching the direction of the tool 18 between the several tool holders 16 on the cross tool holder 15, so as to achieve the effect of quickly replacing different tools 18, which is convenient for production and processing, and there is no need to frequently disassemble the tool 18. The tool 18 can be quickly and accurately replaced, which improves the processing efficiency and avoids the frequent installation and disassembly of the tool 18 when the tool 18 needs to be replaced. In the next step, the third motor 22 is controlled by the control panel 19 to rotate the third rotating shaft 23, so that the slider 25 slides in the corresponding slide groove 21, so that the knife die 26 installed at the upper end of the slider 25 moves back and forth, and the required knife die 26 is adjusted to be directly below the tool 18, thereby avoiding the problem of frequent replacement of the knife die 26 when processing different angles of bending.
