[0024] It should be noted that the U-shaped frames 1 of the two material receiving units are connected and can be fixedly connected by bolts or other means.

[0025] Preferably, the moving track comprises two sliding tracks 5 arranged in parallel and at intervals, and an end stopper 4 is respectively installed at both ends of each sliding track 5, so as to limit the movement of the docking unit;
