The lengths of the three guide columns 6 are shortened from front to back, and the front ends of the three guide columns 6 are all located in the same horizontal plane.

[0035] like Figure 1 , 3 As shown in Figure 4, a mounting plate 8 is fixed to one end of the top chest member 1, and the mounting plate 8 covers the cavity 3. The support member includes a slide plate 9 and a support sponge 10, and the support sponge 10 is fixed to one end of the slide plate 9. The outer wall of the mounting plate 8 has three protrusions 11 corresponding to the three slide plates 9, and the three protrusions 11 are distributed in an annular shape on the outer wall of the mounting plate 8.
