New description: [New technical field] This creation relates to the construction of a boring cutter head, especially a boring cutter head that is tightly coupled to a blade holder. [Prior Art] A boring cutter head having a detachable blade is provided with a shank (40) as shown in the sixth and sixth figures, and a joint seat is formed around the top of the arbor (40). , the left and right sides of the surface of the α β seat (41) are provided with two moneys (42), and a blade seat (43) is provided, and the bottom of the blade seat (43) is opened on the inner surface of the screw lock portion (44). ... screw lock v into the sloping groove (45) to the groove 'top: a blade (46) is slidably locked in a detachable manner. Although the aforementioned boring head can be used for convenience of # μ m i . The user replaces the blade (46) to reach the square insert (42), and the lack of the -) recess (45) only covers between the two (45) and the insert (42). The problem of the groove. There is a work gap, causing the blade seat (43) to be fixed enough. f New content] Because the blade seat of the boring head is not tight enough, the purpose of the sin contact between the taste and the person is to insert the inner mountain. Disadvantages. The creation of the main dragon and the ditch between the formation of the oblique 'plus the knife and the inner face of the seat and the eight wide master g self-defeating "forced structure of the solid lock is indeed effective. Surface design of the design" to reach the blade seat to achieve the above M The creation department provides a boring cutter head which is closely coupled with the blade holder M363355, and comprises: a shank which is formed around the top portion to form a joint seat, the surface of the joint seat is a vertical surface, and a vertical portion is formed there. On the restraint side, a screw hole is placed in the center of the vertical restraining surface, and two sides of the screw hole are protruded from the vertical restraining surface to form two insets Ci' j Η 八 丨; to the book 0 π double 33⁄4 々 V is called a slanted restraint from the bottom and the bottom, each obliquely bound to the slope; and ~, ... π. - ' ^ I ~ ^ non / Τ;, 皤 box order, / sitting vertical restraint' The screw lock portion corresponds to the screw hole through the countersunk hole, and is provided with a bolt. The bolt is threaded through the counterbore hole and screwed into the screw hole, and the deer forms a groove on the inner surface of the screw lock portion. Nested in the recessed groove, recognizing 犮,: 垄T百/曰il 1” t? >, 丄^ a blade holder 'the bottom of the blade holder The part corresponding to the joint forms a screw-locking portion 'the inner surface of the screw-locking portion is flat" and presses against the two inserts of the joint seat... π吻肷洱欣#在两嵌a block forming an abutting surface on each of the top side and the bottom side surface of the recessed groove, each of the facing surfaces being inclined and I; forcing against the respective oblique restraining surfaces of the fitting, further created at the bottom of the arbor Forming a plunger, a head is disposed at a top end of the plunger, and a concave portion is formed on a circumferential side of the head, and the joint is disc-shaped and formed in the concave portion, and the vertical surface of the vertical/1 The two inserts are formed on the left side of the screw hole, and the face is rounded. When the blade holder of the present invention is screwed to the knot of the cutter bar: the right side. When the inner surface of the screw lock portion is pressed against the vertical swaying 53 main body, the slanting restraint surface of the insert block is matched with the abutting surface of the soil and the abutting surface, and the slanted slats are combined with When the seat is combined, it can be inclined: the 7-snail snail locks the knives, and the 面 迫 'forces the tightness of each face when the eyes are combined with the area of the larger contact combination... occupies the seat when it is in use It will not produce the effect of whitening and solid locking, which will make the knife shake or loosen the processing effect. Month opening ^ 'Achieve better [Embodiment] 4 M363355 This is a preferred embodiment of a through hole ^ to four figure that closely combines the blade holder, including: s, please refer to the first tool bar (10) a shank (1 彳) is formed at the bottom, and a - head (12) is provided at the end, and the top of the two shanks (1) around the head (彳2) is formed in the concave portion (13). The joint (14^-the outer surface of the recess (13) is formed into a circular shape and the vertical seat (14) is disposed at the center of the vertical restraining surface (15) with a snail> } Corresponding to the screw hole (16), the right side 'the two protrusions protrude outward from the vertical restraining surface (15), and the two blocks (17) are symmetrically arranged, and each is on the inner end: two The block, each block (17) is wide at the top surface and the bottom outer end (171), and each of the inserts (17) is beveled. ^The face-blade seat (2(D)' has a bottom corresponding joint (14) Forming a screw (21), a screw-locking portion (21-shaped block body, and a middle (four) threaded hole (16) through the countersunk hole (22), the inner surface of the screw lock portion (21) is flat and Urgent form against vertical restraint (1 5), in the inner part of the screw lock (21) facing the gallery two pieces (17) recessed - the road extends in the lateral direction (four) groove (23) n groove (23) enemies in the two inserts (17) 'ditch (23) a long groove having a narrow inner end, and an abutting surface (231) on each of the top side and the bottom side surface, each abutting surface (231) being inclined and abutting against the mating type in an urgent manner Each oblique restraint surface (171) is positioned with a bolt (24), and the thread check (24) is threaded through the counterbore (22) and screwed into the screw hole (16), thereby inserting the blade seat (2〇) Locked to the joint (14). A blade (30) is a double-edged blade body and forms a blade (31) at each of the three corners, and the blade (30) is detachably coupled to the blade seat in a detachable manner ( The top of the 2 0) is used to provide the M363355 for the creation of the pupil cut with each blade (3彳). Please refer to the second to fourth figure, when the creation J is used as the women's blade holder (20), the blade is first (30) Screw lock on the blade holder (2〇).
