Six plug-in seats 4 are provided, and they are equidistantly distributed along the top of the base plate 1 and the top plate 3. Various models of plug-in seats 4 can be used to expand the compatibility range of the equipment. The protective assembly 5 is connected to the end of the plug-in seats 4 and includes a rubber pad 501, a slot 502, a protective plate 503, a connecting plate 504, and a locking block 505. A rubber pad 501 is adhered to one side of the plug-in seat 4, and slots 502 are symmetrically provided on both sides of the plug-in seat 4. A protective plate 503 abuts against one side of the rubber pad 501, and connecting plates 504 are symmetrically arranged at both ends of the protective plate 503. Both the rubber pad 501 and the protective plate 503 are mesh-like, and the rubber pad 501... The holes on the protective plate 503 and the plug-in 4 correspond one-to-one. The replaceable protective plate 503 is used to protect the end of the plug-in 4, avoiding wear and tear that would require replacement of the entire plug-in 4, thus reducing maintenance costs. At the same time, the cushioning performance of the rubber pad 501 enhances the protective effect. A locking block 505 is fixed on one side of the connecting plate 504. The width of the locking groove 502 is equal to the width of the connecting plate 504, and the locking groove 502 is engaged with the plug-in 4 through the connecting plate 504. The locking groove 502 can limit the vertical movement of the connecting plate 504. The locking block 505 is engaged with the plug-in 4 through the locking groove 502, and the cross-section of the locking block 505 is a right trapezoid. When the worn protective plate 503 needs to be replaced, simply forcefully move the connecting plate 504 to bend it, and the locking block 505 can be removed from the protective plate 503, thus quickly disassembling and replacing the protective plate 503.

[0018] like Figure 1As shown, dustproof components 6 are provided on the top of both the base plate 1 and the top plate 3. The dustproof component 6 includes a support plate 601, a damping shaft 602, and a support arm 603.
