[0018] A symmetrically distributed inserting rod 2 is rotatably passed through one side of the top of the workbench 1 close to the connecting plate 16 , and a pushing roller 21 is fixedly sleeved on the outer sides of the two inserting rods 2 .

[0019] An electric push rod 3 is provided on the side of the flip column 18 away from the workbench 1. A through hole 31 communicating with the rectangular groove 19 is opened inside the flip column 18. The output end of the electric push rod 3 is located in the through hole 31. By driving the electric push rod 3, its output end can push the rectangular tube in the rectangular groove 19 to move, so that the rectangular tube can be better detached from the rectangular groove 19.

[0020] A symmetrically distributed mounting plate 4 is fixedly installed on one side of the connecting plate 16 close to the electric push rod 3, and a cross plate 41 is fixedly installed on the opposite sides of the two mounting plates 4. The electric push rod 3 is fixedly passed through the cross plate 41. By setting the mounting plate 4 and the cross plate 41, the electric push rod 3 can be supported and its stability can be improved.

[0021] A first motor 5 is coaxially fixedly installed at one end of the rotating shaft 193 away from the pinion 192, and a second motor 51 is coaxially fixedly installed at the bottom of one of the insertion rods 2. By setting the first motor 5, it is convenient to drive the rotating shaft 193 to rotate, thereby realizing the flipping of the rectangular tube.

The rectangular tube enters the fixed frame 11 and comes to the middle of the two grinding rollers 13, and is polished by the grinding roller 13. Then the rectangular tube continues to move, and moves through the conveying roller 15 on the other side of the top of the workbench 1, until the rectangular tube enters the rectangular groove 19, and rotates by driving the rotating shaft 193, driving the small gear 192 to rotate, and the small gear 192 drives the flip column 18 to rotate through the large gear 191, so that the flip column 18 drives the rectangular tube to rotate. Rotate, and then drive the conveying roller 15 in reverse to drive the rectangular tube back to the middle of the two grinding rollers 13, so as to complete the all-round grinding of the rectangular tube; it should be noted that: the conveying roller 15 and the grinding roller 13 are common driving methods on the market, which will not be elaborated here; by driving the insertion rod 2 to rotate, the pushing roller 21 is driven to rotate, so that the two pushing rollers 21 apply thrust to the rectangular tube, so that one end of the rectangular tube can be completely entered into the rectangular groove 19, which is convenient for the flipping column 18 to flip the rectangular tube, and by driving the insertion rod 2 in reverse, the rectangular tube can be driven to detach from the rectangular groove 19.
