This creation is about a boring tool holder structure (2), especially an innovative structural designer for a convenient socket assembly expansion tool.

According to the present invention, as shown in the fifth figure, the end face of a cutter shaft (1) runs through an active space (S), and the first side wall (2) of the top surface of the cutter shaft (1) and The second side wall (3) is screwed to fix two cutter seats, each of the cutter seats has a convex block, and a blade is respectively screwed on the left and right opposite positions of the two cutter seats, and then the blade is rotated by the high speed drive cutter shaft. Cutting path, according to which the blade is used to cut the working object, however, when the first side wall (2) of the arbor (1) and the outer edge of the second side wall (3) are intended to fit a sleeve clamp, etc. When the tool is expanded, the inner space of the cutter shaft (1) is not provided with a retracting space such as an indented groove for providing the first side wall (2) and the second side wall (3). The expansion tool such as the collet is not easy to be assembled and assembled on the outer edge of the first side wall (2) and the second side wall (3).

Therefore, in view of the problems existing in the above-mentioned conventional boring tool holder structure, how to develop an innovative structure with more ideal and practicality, the consumers are eagerly awaited, and the relevant industry must strive to develop the breakthrough goal and direction. .

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

That is, the main purpose of the present invention is to provide a boring holder structure (2); the problem to be solved is that the first side wall of the arbor is present for the conventional boring holder and When the outer edge of the second side wall is to be used for enclosing an expansion tool such as a sleeve clamp, a recessed space such as an indented groove for providing the first side wall and the second side wall is not disposed in the center of the cutter shaft relative to the movable space. And the expansion tool such as the sleeve clamp is not easy to be assembled and assembled on the outer side of the first side wall and the second side wall to improve the breakthrough; and the technical feature of solving the problem is mainly by including a cutter shaft, the cutter a first side wall and a second side wall are disposed on the upper end of the shaft, and an active space is disposed between the first side wall and the second side wall, wherein the first side wall is provided with a first seat corresponding to the movable space position, and the first side wall is disposed The second side wall is provided with a second knife seat corresponding to the position of the movable space, and the first blade seat and the second blade side edge are respectively provided with a first blade and a second blade, and the first side wall and the second side are respectively The laterally predetermined positions of the side walls are respectively provided with a wearer And a screw hole, the through hole and the screw hole are locked by a limit bolt; the corner groove compression space is formed at a position of the corner of the cutter shaft relative to the first side wall and the second side wall and corresponding to Connected to the active space, thereby providing a displacement adjuster for lateral compression or reset expansion of the first side wall and the second side wall relative to the angular groove compression space; thereby creating a unique design, thereby enabling the creation The corner groove compression space enables the first side wall to reach a reset expansion or a pressure contraction state with respect to the second side wall, thereby facilitating the deployment of a socket assembly and other expansion tools, thereby enabling the creation of the present invention. Practical and progressive people who use convenience.

Please refer to the first to fourth figures, which are preferred embodiments of the present invention, but the embodiments are for illustrative purposes only, and are not limited by the structure in the patent application. The system includes a first shaft (20) and a second side wall (40). The first side wall (20) and the second side wall (40) are respectively disposed at an upper end of the shaft (10). An active space (S) is disposed between the first side wall (20) and a first seat (30) corresponding to the active space (S), and the second side wall (40) corresponds to the movable space ( a second blade holder (50) is disposed at a position of the first blade holder (30) and the second blade holder (50), and a first blade (31) and a second blade (51) are respectively disposed at the side edge of the second blade holder (50). And a through hole (21) and a screw hole (41) are respectively disposed in a laterally predetermined position of the first side wall (20) and the second side wall (40), and are screwed by a limit bolt (60). The first hole (21) and the second seat (50) are respectively provided with a first limit relative to the through hole (21) and the screw hole (41); a slot (32) and a second slot (52); a corner groove compression space (12) is provided on the cutter shaft (10) corresponding to the angular position of the first side wall (20) and the second side wall (40) and correspondingly connected to the movable space (S), thereby providing the first side wall (20) and the second side wall (40) A displacement adjuster for lateral compression or retraction expansion with respect to the angular groove compression space (12). In addition, the top center of the cutter shaft (10) is provided with a slotted compression space (11) corresponding to the movable space (S), thereby further providing the first side wall (20) and the second side wall (40) to be compressed relative to the slot. Space (11) for lateral compression or retraction Displacement adjuster.

With the above structure and composition design, the operation of the present invention is described as follows: when the outer edge of the first side wall (20) and the second side wall (40) is to be sleeved with a predetermined sleeve clamp, the user The limiting bolt (60) can be screwed by an adjusting tool (T), and the limiting bolt (60) is screwed to the screw hole (41) of the second side wall (40) to make the screw hole (41) A displacement lateral force is generated by the limit bolt (60), and the angular groove compression space (12) is caused by a lateral force to generate a pressurized contraction state, facilitating the first side wall (20). And the outer edge of the second side wall (40) is sleeved with a predetermined sleeve clamp (not shown), and when the sleeve is completed, the adjustment tool (T) can be loosened to the limit bolt (60), so that The first side wall (20) and the second side wall (40) are reverted to a normal space state with respect to the corner groove compression space (12), thereby reaching a predetermined sleeve clamp and the first side wall (20) and the second side wall. (40) A state of tension is generated.

Accordingly, the creation of the first side wall (20) relative to the second side wall (40) by the corner groove compression space (12) can achieve a reset expansion or a pressurized contraction state with respect to the second side wall (40), thereby facilitating the configuration of the sleeve. It is also possible to assemble a sleeve clamp and other expansion tools to make the creation of the creation more convenient and practical.

By summarizing the above description, the design of the above structure can effectively overcome the shortcomings faced by the new style of the formula, and further has the above-mentioned numerous advantages and practical value, so this creation is an innovative new creation, and in the same There is no identical or similar product creation or public use in the technical field, so this creation has met the novelty and progressiveness of the new patent. The requirements are to apply in accordance with the law.
