In this way, by arranging a plurality of hard rings 603, the axial compression of the elastic body 600 during compression deformation can be guided, and the phenomenon of compression bending and jamming of the elastic body 600 can be avoided.

[0052] In this embodiment, the elastic body 600 has a deformation section 601 located between adjacent hard rings 603, and the deformation section 601 is compressed and deformed during compression deformation of the elastic body 600 pressed by the ball 500 towards the high position end 204; the inside of the deformation section 601 is arranged in a hollow manner, and a hollow cavity 604 is formed, and the two ends of the hollow cavity 604 are arranged in a closed manner and are arranged in alignment with the inside and outside of the hard ring 603.

[0058] When the goods 400 are placed on the two fork frames 300, the goods 400 press the elastic blocks 303 to compress and deform downward until the top of the elastic blocks 303 is compressed into the recessed grooves 302, and the elastic spacing 304 is reduced.

[0059] In this way, the multiple elastic blocks 303 play a role of elastic support on the bottom of the goods 400. When the goods 400 are in a vibrating state during the process of carrying the goods 400, the multiple elastic blocks 303 can play a role of elastic support on the bottom of the goods 400, and at the same time can play a role of buffering vibration through elastic deformation. In addition, the multiple elastic blocks 303 are arranged in a circumferential interval around the recessed grooves 302, thereby playing a role of full circumferential elastic buffering and manufacturing.

[0060] In addition, the multiple balls 500 are on the top of the goods 400, and at the same time play a role of elastic pressing. In cooperation with the elastic deformation of the elastic body 600, the multiple balls 500 can move in the arc-shaped grooves 202 in an arc shape, and play a role of elastic pressing on the top of the goods 400, thereby playing a role of buffering vibration.
