[0028] The rectangular metal product fixing mechanism 4 includes a second lead screw 41. The end of the second lead screw 41 penetrates through the inside of the first lead screw 31 and the U-shaped frame 32 and is rotatably connected to the middle of one side of the pressing plate 42 through a bearing. The end of one side of the pressing plate 42 is fixed with a second limiting rod 43, and the end of the second limiting rod 43 penetrates through the inside of the U-shaped frame 32 and the vertical plate 2.

[0029] There are two first lead screws 31, U-shaped frames 32 and first limiting rods 34 symmetrically distributed about the central axis of the table 1, and there are two pressing rods 33 symmetrically distributed about the central axis of the U-shaped frame 32. The vertical plate 2 and the first lead screw 31 are in threaded connection, and the first limiting rod 34 and the vertical plate 2 are in sliding connection, ensuring that when the two left and right first lead screws 31 rotate simultaneously, the two U-shaped frames 32 can move closer to each other, and the two U-shaped frames 32 can drive the two left pressing rods 33 and the two right pressing rods 33 to move closer to each other, so as to complete the fixation of circular metal products with different diameters.

[0030] A first fixing rod 35 is fixed to the outer wall of one end of the first lead screw 31 away from the U-shaped frame 32, which facilitates the rotation of the first lead screw 31 through the first fixing rod 35.

The two U-shaped frames 32 drive the two abutting rods 33 on the left and the two abutting rods 33 on the right to move closer to each other, completing the fixation of the circular metal product. The state of the circular metal product after fixation is as Figure 1 shown;

[0035] Place the rectangular metal product at the center of the top of the table 1, and then rotate the two second lead screws 41 simultaneously through the second fixing rod 44.
