When the movable track 1 swings, the column 5 stops moving after touching the stopper 6.

[0018] In order to facilitate the cylinder to control the swing trajectory of the turntable 2, sliding holes 11 are symmetrically arranged on both sides of the turntable 2, and push blocks 12 are arranged in the sliding holes 11. The two push blocks 12 are respectively connected to the telescopic ends of the first driving cylinder 3 and the second driving cylinder 4. The turntable 2 is a semicircular structure, and the shape of the sliding hole 11 is an arc with the same curvature as the turntable 2.
