At this time, the chamfer of the concave plate 13 will contact the chamfer of the L-shaped plate 15, so that the two L-shaped plates 15 are close, and the clamping column 16 is further disengaged from the clamping hole. After the end face of the concave plate 13 conflicts with the outer wall of the L-shaped plate 15, it will be unable to move.

After the glass fragments are poured into the waste collection box 33, the reduction motor 24 drives the threaded rod 21 to rotate, and the threaded rod 21 drives the U-shaped plate 22 to move up along the second slide rod 34. At this time, under the action of the bending spring, the support plate 4 returns to the horizontal position, and then under the action of the spring, the T-shaped clamping plate 6 returns to its original position, pulling the pull rope 8, and further the concave plate 13 returns to its original position. Under the action of the spring, the L-shaped plate 15 will also return to its original position, and the clamping column 16 will be re-engaged with the clamping hole.
