Therefore, the L-shaped connecting rod 17 will be able to drive the second sliding mechanism to move upward, thereby driving the sliding plate 20 to move upward, and the sliding plate 20 drives the waste storage box 6 to move upward. Therefore, when clamping steel rods 5 of different calibers, the distance between the waste storage box 6 and the top of the steel rod 5 is almost the same. Therefore, it can be ensured that when processing different steel rods, the waste storage box 6 can collect the waste chips well.

[0023] In a specific embodiment, the first sliding mechanism includes four first slide grooves 10, which are respectively opened on the two opposite side walls of the two placement slots 4, and the four first slide grooves 10 are symmetrical to each other.

In this configuration, the installation position and components of the transmission mechanism are determined.

[0026] Further, the second sliding mechanism includes four second slide grooves 22, which are respectively provided on the two opposite side walls of the inner cavity of the two rectangular grooves 19, and the four second slide grooves 22 are symmetrical with each other, and the second slide bars 21 are slidably arranged between the four second slide grooves 22, and the inner walls of the four second slide grooves 22 are all provided with second rectangular notches 18, and the inner cavities of the four second rectangular notches 18 are all provided with L-shaped connecting rods 17, and one end of the four L-shaped connecting rods 17 is respectively connected to the second slide bars 21.

[0027] Furthermore, a sliding plate 20 is fixedly mounted on one side wall opposite to the two second slide bars 21, and a waste storage box 6 is connected to one side wall opposite to the two slide bars 20. In this configuration, when the L-shaped connecting rod 17 moves upward, the L-shaped connecting rod 17 will be able to drive the second sliding mechanism to move upward, thereby driving the sliding plate 20 to move upward, and the sliding plate 20 drives the waste storage box 6 to move upward, so when clamping steel bars 5 of different calibers, the distance between the waste storage box 6 and the top of the steel bar 5 is almost the same, so it can be ensured that when processing different steel bars, the waste storage box 6 can collect the waste well.
