Description of the invention: [Technical field to which the invention pertains] - Improved shank structure for gripping tools, and shank for clamping use in hole ring drilling operations such as metal materials, etc. 'About a simple loading and unloading of circular drilling tools; = [Prior Art] In the field of circular hole drilling technology, usually a drilling body with a drilling edge at the lower end of the rotation, and circular drilling at a constant speed The operation of the tool, because of the need to replace the tool with the diameter of the drill hole, has enabled the industry to develop the tool holders for the various cutting tools required for round hole drilling, and it is easy and quick to implement the tool change operation. 8. The first figure shows the conventional tool holder (1), one end of which is the driving part (11) and the other end of which is the cylindrical sleeve part (12), and the head (14) of the tool (13) is inserted into the socket. Department (12). One end of the cutter (13) different from the head (14) is a cylindrical cutting edge (15), which is inserted into the shank by the center drill (16) with the insertion end (17) through the hole (18) in the center of the cutter (13) (丨), the shank (q) is used to tighten the fixed tool (13) and the center drill (16) by means of the screwing element (19), respectively. The reaction force generated when the workpiece is drilled is directly transmitted to the tool (13). And the center drill (16), so it is easy to cause the screwing element (19) to loosen, so that the cutter (13) or the center drill (16) is thus detached from the control of the shank (1). In addition, the head (14) of the tightening tool (13), even the insertion end (17) of the center drill (16), may have a slight spacing from the inside of the shank (1). The pitch is the error of 200906540 caused by the machining. This spacing depends on the screwing element (19). It is impossible to eliminate the possibility that the tool (13) or the center drill (16) in the operating period can be retracted into the shank (丨). , has been enough to affect the quality and accuracy of the hole cutting. For example, the second and third figures show the structure of another quick-disconnecting round hole drill. The shank (2) is sleeved with a ring-shaped cutter (21). The cutter (21) is centrally connected with a center tip (22). (23) The mechanism in which the sleeve (23) rolls at different inner diameters easily loosens or bonds the cutter (21) to the shank (2). With such a simple construction, since the depth of the ball socket (25) is different, the beads (23) are trapped in the ball socket (25), and a slight gap is formed with the inner diameter of the sleeve (24). Swinging and shaking on the shank (1) indirectly affects the accuracy of the center tip (22).
