Embodiment
The technological means and its effect taken for further elaboration the utility model, below in conjunction with the utility model
Preferred embodiment and its attached drawing are described in detail.
With reference to figure 1-3, the buffer unit between a kind of lathe extensible cover, including 100 stent of protective cover, be movably set in
The multiple protective covers 100 for being connected with each other on protective stent and can stretching or be superimposed along 100 stent of protective cover, the protective cover
100 include tablet 120 and the riser 110 being connected with tablet 120, and the edge of the riser 110 is equipped with multiple notches, the groove
Mouth is equipped with cushion pad 200, and the scraper plate 300 for being placed in the lower section of cushion pad 200 is equipped between the protective cover of interconnection, described to scrape
The dust that plate 300 strikes off 110 surface of riser in 100 telescopic process of protective cover is cut, avoids stretching shadow of the dust to protective cover 100
Ring and dedusting beauty function.
The cushion pad 200 includes the first packing ring 210, second packing ring 220, connecting portion 230 and inner ring 240, and described first
The thickness of packing ring 210 is more than the thickness of second packing ring 220；The connecting portion 230 connects the first packing ring 210 and second packing ring 220；
The inner ring 240 is arranged in the inner ring surface of second packing ring 220；First packing ring 210 is arranged on 100 riser 110 of a protective cover
On the inside of the cover body of edge, and block is in the inner side of 100 riser 110 of protective cover of another interconnection, the second packing ring
