DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a type of clamping device and, in particular, to a knife holder for mounting on a road planer, various rotary drilling machines or grinders. Device. Eight [Prior Art] A cutter and tool-hokiing device of a drill tool, such as China's certificate number: η?%%, No. 275697. These tool holders and tool holding devices are used to create scrap road pavement, (4) minerals, drilling or surface roughing. The tool holding device as described above includes a base phase fixed to the outer peripheral surface of the actuator (domain wheel) of the implement and a clamp seat coupled to the base member, the clamp holder for mounting the cutter And the locking component is locked on the base member. The tool is mounted on the clamping seat and needs to form a tangential angle with the base member to facilitate the application of the drilling and planing force to the workpiece. At the time of processing of the drilling tool, the workpiece was subjected to a forced drilling operation by the blade of the cutter, and the movement of the roller was followed by the action of the workpiece to perform the destruction. The purpose of things (such as cement, asphalt on road pavement). In addition, because the workpiece is usually provided with a solid structure, and the service life of the tool is quite limited, it is known that it is necessary to update frequently. However, due to the reaction force at the time of processing, the reaction is not only feedback to the tool body. It is also added to the body of the holder. Therefore, if the strength between the holder 200914713 and the base member is not strong enough, the loss of the seat must be followed by the replacement of the tool at the same time, which will result in a significant increase in the cost of use. It can be seen from the above that under the rigid appearance of the workpiece, the assembly strength of the tool holding devices is particularly important in order to achieve the desired processing. Taking the road planing machine as an example, when the tool on the roller performs the rotary planing operation, due to the force of the tool for drilling the planed road surface, a feedback force is also formed on the tool holder body, and the reaction force is generated. That is, the fatal wound of the knife seat, "the operation of the machine in the (four) machine is not normal, which will cause the service life of the tool holder body to be reduced. Therefore, how to improve the combination between the base member and the clamp seat of the tool holding device Strength, and increased service life and lower cost of use' are the goals that the industry is not striving for.
