One end of the screw rod 5 passes through the inner walls of the two bearings 4 in sequence and is fixedly connected to the inner walls thereof, and a rotating rod 6 is fixedly installed on the other end of the screw rod 5, and the screw rod 5 is rotatably fixed in the operating block 1, and the screw rod 5 can be driven to rotate in the operating block 1 by driving the rotating rod 6. A fixing plate 2 is fixedly installed on the front and rear sides of one end of the operating block 1 away from the mounting block 13, and a fixing hole is opened on the side wall of the fixing plate 2. The device can be fixed to one side of the aluminum tube bending machine by passing one end of a bolt through the fixing hole on the fixing plate 2.

[0023] A threaded sleeve 7 is threadedly connected to the outer wall of the screw rod 5, and a slide plate 8 is fixedly installed on the outer wall of one end of the threaded sleeve 7. The slide plate 8 and the strip hole 3 are slidably connected. A support block is fixedly installed on the outer wall of the upper end of the threaded sleeve 7. The slide plate 8 is provided with two pieces, and the slide plate 8 is fixedly installed on the upper end of the support block. The two slide plates 8 are respectively located at the upper and lower ends of the strip hole 3. A threaded rod 9 is fixedly installed on the upper end of the slide plate 8. The upper end of the slide plate 8 is rotatably connected with an anti-slip sleeve 11. The outer wall of the threaded rod 9 is sleeved with a bearing 2 10, and the anti-slip sleeve 11 is fixedly installed on the outer wall of the bearing 2 10. The upper end of the threaded rod 9 is threadedly connected with a nut, which fixes the bearing 2 10 and the anti-slip sleeve 11. When the bearing 2 10 and the anti-slip sleeve 11 need to be replaced, the nut can be unscrewed, which facilitates disassembly and assembly.

[0024] The front and rear sides of one end of the operating block 1 are symmetrically fixed with mounting blocks 13, and the upper end of each mounting block 13 is rotatably connected to a limiting sleeve 16, and the upper end of each mounting block 13 is fixedly mounted with a threaded rod 2 14, and the outer end of the threaded rod 2 14 is sleeved with a bearing 3 15, and the outer end of the bearing 3 15 is fixedly mounted with a limiting sleeve 16, and an arc-shaped limiting groove is provided on the outer wall of the limiting sleeve 16, and a nut is threadedly connected to the upper end of the threaded rod 2 14 to fix the bearing 3 15 and the limiting sleeve 16.
