A circle shear device for cutting holes in sheet metal as in claim 13 wherein said upper center shaft is vertically reciprocated between a first upward rest position and a second lowered operating position wherein: a said first upward position raises said first upper cutter wheel a sufficient distance to permit the unobstructed exchange of additional provided metal sheet through said cutting jaw; and b said vertical reciprocation means includes an pneumatic air cylinder.

削减的孔一个圆盘剪设备在金属板在要求13，说的上部中轴垂直被交换在第一个向上静止位置和第二个被降下的工作位置之间，： a首先说的向上位置培养说的第一个上部切削刀轮子一个充足的距离通过说的切开的下颌允许另外的提供的金属板通畅的交换；并且 b说的垂直的往复手段包括一个气动力学的空气圆筒。

Meanwhile, the next round in the policy holding stability and trigger a rebound in market, bank stocks led the mainstream varieties led the stock shock was the way its own run-pattern of the adjustment disk does not have a decent appearance in the continued upward, the technical adjustment of the pressure began to increased, both on K-line in order to cross-Star received shows that differences of both short-term long-short market, has significantly increased, the market volatility will inevitably increase.

同时，本轮在政策维稳下引发的反弹行情，以银行股为首的主流品种领涨，股指呈一路震荡盘升格局，盘中没有像样的调整出现，在持续上行后，技术上的调整压力开始加大，日K线双双以十字星报收显示，短线市场多空双方的分岐明显加大，市场震荡加剧难免。
