[0042] Working principle:

[0043] After the upper cylinder 10 is raised, the support plate 31 is moved upward, and then the support block 34 in the through hole 33 is pushed. The limiting plate 35 is attached to the support plate 31, so that the support block 34 extends into the inner side of the lower end of the upper cylinder 10. The support plate 31 is moved further. When the upper end of the support block 34 is attached to the bottom of the upper cylinder 10, the nut on the second bolt 30 in the waist hole 32 is tightened.
