There are several movable fork teeth 5, and one end of the several movable fork teeth 5 close to the fork frame 1 is connected together through a connecting plate 6. The several movable fork teeth 5 are rotatably and foldably mounted and connected to the fork frame 1. By making the several movable fork teeth 5 and the fixed fork teeth 2 "coplanar", it is in the working state of the "multi-tooth structure" at this time. By folding and contracting the several movable fork teeth 5, leaving two fixed fork teeth 2, it is in the working state of the "two-tooth structure" at this time.

[0027] In an embodiment, hinge seats are respectively connected to one ends of several movable fork teeth 5 close to the fork frame. The movable fork teeth 5 are rotatably and foldably installed and connected to the bottom end of one end of the fork frame 1 close to the movable fork teeth 5 through the hinge seats. At the same time, folding cylinders 7 are respectively arranged on both sides of the connecting plate 6. One ends of the folding cylinders 7 are respectively hinged to the connecting plate 6 through hinge seats, and the other ends of the folding cylinders 7 are respectively hinged to the upper part of the fork frame 1 through hinge seats.
