The invention discloses a tool bit structure of a road grooving machine, which comprises a driving shaft and a sleeve, wherein a limiting ring is fixed on the outer wall of the driving shaft, a key groove distributed in the length direction of the driving shaft is formed in the driving shaft, one end of the key groove extends to the end face of the driving shaft, the other end of the key groove extends to the limiting ring, a flat key is arranged in the key groove, and a threaded connection part is arranged on the outer wall of the end, which is away from the limiting ring, of the driving shaft; the sleeve is arranged on the outer wall of the driving shaft and the outer wall of the flat key in a sleeving mode; the transition between a blade and the driving shaft is realized by arranging the sleeve structure, by means of flat key connection between the sleeve and the driving shaft, a large contact surface between the sleeve and the flat key is achieved, breakage of the flat key caused by overlarge torque is avoided, the sleeve and the blade are pressed through a nut to form a whole, and the sleeve can be directly detached during detaching, so that quick disassembly and replacement are achieved, and the operation is easy and convenient.
一种道路开槽机的刀头结构，包括：驱动轴，所述驱动轴的外壁固定有限位环，所述驱动轴上开设有沿其长度方向分布的键槽，所述键槽一端延伸至所述驱动轴的端面，所述键槽的另一端延伸至所述限位环处，所述键槽中设有平键，所述驱动轴远离所述限位环的一端外壁设有螺纹连接部；套筒，所述套筒套设在所述驱动轴和平键的外壁；通过设置套筒结构来实现刀片和驱动轴之间的过渡，利用套筒和驱动轴之间的平键连接，实现与平键之间较大的接触面，避免扭矩过大造成平键的破裂，而套筒和刀片之间利用螺母压紧，形成一个整体，在拆卸时，可以直接将套筒拆除，因此实现快速的拆卸和更换，操作简单方便。
