When limiting the aluminum profile 15, it is necessary to place the aluminum profile 15 in the limiting groove 14, and then use the threaded rod 18 to push the second slider 17 to slide inside the third slide groove 16, so that the clamping block 19 moves to the top of the aluminum profile 15, and then rotate the threaded rod 18 to make the clamping block 19 move downward under the limit of the inner wall of the limiting block 13, thereby clamping the aluminum profile 15, avoiding the aluminum profile 15 from being offset during bending, which is beneficial to improving the qualified rate of bending of the aluminum profile 15.

[0022] There are multiple second chutes 9, which are symmetrically distributed on both sides.

[0023] The front and rear sides of the clamping block 19 are both fitted with the inner side walls of the limiting block 13, and the clamping block 19 is located above the aluminum profile 15. Since the clamping block 19 is limited by the inner side walls of the limiting block 13, the clamping block 19 can only move up and down.
