Through the improvement of the generation, the drill bit replacement of the drilling machine is very convenient, the replacement time of the drill bit is greatly saved, and the replacement difficulty of the drill bit is reduced. But the clamping mode of common drilling machine to the drill bit is comparatively single, and most is tight through tight loose structure to the cylinder of drill bit top, and its elasticity degree relies on the force way that the workman screwed up completely, and then can produce following problem.
The single fastening mode can generate the problem that the force is too large to replace. When an operator clamps the drill bit by using a large force, the drill bit is ensured not to be shifted during working, but the time and the labor are wasted when the drill bit is required to be replaced, and even the drill bit can be taken out by means of a tool.
The single fastening mode can generate the problem that the drill bit with insufficient force is detached. When the force used when the operator clamps the drill bit is insufficient, the drill bit can shake when working to a certain extent, so that the problem of falling off exists, and a certain potential safety hazard can be caused.
The single fastening mode of the drill bit can cause a certain problem due to different force of different people, so that the company now proposes a new structure for solving the technical problems.
