An anti-slip sleeve (not marked in the figure) is covered on the outside of the handwheel 221;

[0035] Operation:

[0036] By rotating the adjustment screw 220 through the handwheel 221, the rotation of the adjustment screw 220 causes the sliding clamp block 230 to slide along the top of the sliding seat 210, thereby adjusting the position of the sliding clamp block 230;

[0037] Please continue to refer to Figures 2-4 . The power component 300 is placed at the bottom of the workbench frame 100 to provide power and change the orientation of the conversion component 400 to adjust the pipe bending method;

A shaft rod 341 is connected inside the transmission gear 340. The top end of the shaft rod 341 extends above the workbench frame 100;

[0039] When the servo motor 310 works, it drives the threaded lead screw 311 to rotate. The threaded seat 312 is in screwed fit with the threaded lead screw 311. When the threaded lead screw 311 rotates, the threaded seat 312 drives the movable plate 330 to slide along the outside of the mounting plate 320, thereby driving the position of the rack 332 to change, causing the transmission gear 340 to rotate;

[0040] Please continue to refer to Figure 1 、 Figure 2 and Figure 4 . The conversion component 400 is rotatably connected to the top of the workbench frame 100, moves synchronously with the power component 300, and is arranged in cooperation with the sliding clamp block 230;

The positions of the right-angle limit block 420 and the bent-angle limit block 430 can be adjusted according to the actual situation to adapt to different pipe bending methods.

[0044] Working principle: When this utility model is in use, the servo motor 310 drives the threaded lead screw 311 to rotate. When the threaded lead screw 311 rotates, the threaded seat 312 drives the movable plate 330 to slide along the outside of the mounting plate 320, thereby driving the position of the rack 332 to change, causing the transmission gear 340 to rotate. When the transmission gear 340 rotates, it drives the connection seat 410 connected to the shaft rod 341 to rotate. The positions of the right-angle limit block 420 and the bent-angle limit block 430 can be adjusted according to the actual situation to adapt to different pipe bending methods.
