Chisel
The invention provides a chisel, which comprises a chisel end, a chisel holder, a holding seat and a limiting disc, wherein a hole with an annular surface is formed around the central axis L of the limiting disc; at least one circle of groove is formed in one side of the limiting disc;a hole penetrates through the groove;the limiting disc is provided with a supporting surface and a first end surface;the groove is transited from the supporting surface to the first end surface;a supporting part is arranged on the holding seat; and the groove is meshed with the supporting part. According to the chisel, the optimal rotary cutting performance can be kept during working, working pressure can be transmitted more effectively, and the service life of the chisel can be prolonged.
本案提供了一种凿刀，包括凿刀端部，凿刀保持部，保持座，限位盘，围绕所述限位盘的中心轴线L形成具有环形面的孔，所述限位盘在其一侧设有至少一圈凹槽，所述凹槽被孔所贯穿，所述限位盘具有支撑面、第一端面，所述凹槽由支撑面过渡到第一端面，所述保持座上具有支承部，所述凹槽与所述支承部相啮合。本案的凿刀在工作时能够保持最优化的旋转切削性能、更有效地传递工作压力，可延长凿刀的使用寿命。
