The second guide columns 14 are arranged in pairs and are arranged in the third connecting holes, so that the fixing seat 31 is movably arranged on the second guide columns 14 in the up-down direction. The other ends of the second guide columns 14 are arranged in the fourth connecting holes, so that the second guide columns 14 are arranged on the bottom plate 12.
