    • PROBLEM TO BE SOLVED: To provide a trimming apparatus of high efficiency in trimming a wall surface in a planar state.
      SOLUTION: A plurality of chisels 50 are supported in a straight line in a direction orthogonal to an axis direction while breaking surfaces 52 are located almost in the same plane, and impact is applied in the axis direction to the plurality of thus supported chisels 50 to carry out separation work. Since the separation work is carried out to the wall surface with the breaking surfaces 52, located almost in the same plane, of the plurality of chisels 50, the wall surface is separated in the planar state with the breaking surfaces 52 of the plurality of chisels 50.

    • 要解决的问题:提供一种在平面状态下修整壁表面的高效率的修剪装置。 解决方案:多个凿子50在与轴线方向正交的方向上以直线方式被支撑,同时破裂表面52几乎位于同一平面中,并且沿轴向方向对多个这样支撑的冲击 凿子50进行分离工作。 由于在多个凿子50中几乎位于同一平面上的破裂面52进行分离工作,所以在平面状态下,壁面与多个凿子的破碎面52分离 50.版权所有(C)2010,JPO&INPIT
