[0009] Preferably, the bent-foot structure includes a first finger blade bent-foot structure and a second finger blade bent-foot structure; the finger blade pressing contact area includes a first finger blade pressing contact area and a second finger blade pressing contact area.

[0010] Preferably, the first and second finger blades are mirror-symmetric structures.

[0011] Preferably, the elastic rotation region of the elastic support belt forms an angle α with the main structure of the support belt, and the range of α is 28°. 。 -36 。 .

[0012] Compared with the closest existing technology, the technical solution provided by this utility model has the following beneficial effects: 1.
