The reamer portion 134 has a blade edge 136 which can be twisted-conical hole 16, and a chip flute 13 7 which can discharge wood chips. • The screw 14 is lockable with the screw hole m. When the user drills and reams a wooden workpiece 15, the first 't' selects the appropriate diameter of the drill tail 12, and the 1 clamped seat 1G that matches the drill tail 12 The rivet portion 134 is inserted into the through hole 132 0 of the body 13 and the screw 14 is locked into the screw hole 133 until the screw 14 is pressed against an abutting surface 121 of the drill tail 12 to make the drill The tail U is sturdyly placed on the cutter holder 1 , to prepare for construction. Although the 1 ° hai red knife holder 10 can be used to hold the drill tail 12 for drilling and boring, but in actual use, it has the following defects: l29〇498 four first, if the user needs to drill different Hole drilling, in addition to the purchase of the corresponding tail directly controlled! In the case of the second, it is also necessary to purchase the cutter holder 10 which matches the diameter, so that the cutter holders of different diameters share the cutter holder 1 〇. Secondly, the drill tail 12 often has a broken and worn condition and needs to be replaced. At this time, the user needs to remove the cutter holder 1 from the electric drill n, and take a tool that can loosen the 4 screw 14 and The screw 14 is loosened and the broken or worn drill tail 12 is removed and another new drill tail 12 is replaced. For the average user, the process is trivial and time consuming, especially in the case of a large number of production rushes. The user simply discards the broken drill tail 12 and the cutter holder 1 , at the same time, and directly replaces the other group. The cutter holder 10' in which the tail 12 is installed thus makes the production cost high. First, in order to prevent the boring tail 12 from rotating relative to the cutter holder 1, the drill tail 12 needs to additionally cut the abutting surface 12 for the screw μ to abut the abutting surface 121, so that the drill tail 12 becomes a special specification of the work, which is higher. Eight or fourth, the blade 136 of the squeegee portion 134 can be used to twist the cone 16 ' of the drilled hole 12, but the user does not easily control the depth of the tapered hole 16. Referring to the right diagram of Fig. 2, the depth of the tapered hole 16 is deeper than that of the left figure, so the construction quality is not easily controlled. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cutter holder that can quickly disassemble a drill tail that can be easily attached and detached. Therefore, the cutter holder for quickly disassembling the drill tail of the present invention is detachably 6 1290498 and is attached to a drilling device, and can hold a drill tail. The cutter holder includes a seat body and a top cover. a connecting post, a three-pronged jaw block, and a three-replacement magazine 0 " a compass body comprising a surrounding wall surrounding an axis, a perforation defined by the surrounding wall, and a knives having a surrounding wall Around the inner peripheral surface of the perforation, the inner peripheral mask has a conical section having a cutting edge and a chip flute adjacent to the cutter. The I I top cover can close one end of the perforation and has a threaded perforation that communicates with the perforation. The connecting post is threaded into the threaded perforation and has a threaded section that is screwed into the threaded perforation and a connecting section that can be coupled to the drilling apparatus. The jaw blocks are received in the perforation and are slidable along the conical section. When the threaded section of the connecting post is screwed into the screw perforation, the connecting post can push the jaw blocks while opposing The conical section slides, which in turn presses the tail. The return springs are respectively connected between the two jaw blocks, and when the thread segments of the connecting rod are screwed back in the screw perforations, the jaw blocks slide upward due to the action of the return springs. Then relax the drill tail. The jaws are placed in the body of the knives, and the jaws are pushed up by the connecting column, so that the jaws can be tightened or loosened for convenient use. Quickly disassemble the drill tail. [Embodiment] The foregoing and other technical contents, features and advantages of the present invention will be apparent from the detailed description of the three preferred embodiments of the present invention. Before the present invention is described in detail, it is to be noted that in the following description, similar elements are denoted by the same reference numerals. As shown in Figures 3, 4, and 5, the present invention can quickly disassemble the boring cutter holder of the drill tail and mount it on an electric or a pneumatic drilling device 21, and can hold a drill tail 22 〇 The first preferred embodiment includes a body 3〇, a top cover 4〇, a connecting post 50, a triple jaw block 60, and a triple return spring 70. The seat body 30 includes a surrounding wall 31 surrounding an axis L1, a perforation 32 defined by a surrounding wall 31, a knives 33, and a plurality of slids 34. The surrounding wall 31 has a large diameter section. 311. A small diameter section 312 having a diameter smaller than the large diameter section 311, a connecting diameter connecting the large and small diameter sections 311 and 312 and having a diameter gradually reduced by the large diameter 4 and 3 11 toward the small diameter section 3 12 a segment 3 13 , an inner circumferential surface 314 surrounding the through hole 32 , an outer circumferential surface 3 15 ′ disposed opposite the inner circumferential surface 314 , and an external thread 3 16 formed on the outer circumferential surface 315 of the small diameter segment 312 . The inner peripheral surface 314 has a pair of large inner circumferences 317 which should have large diameter sections 311, a pair of small inner circumference sections 318 which should be small diameter sections 312, a pair of conical sections 319 which should be connected to the diameter sections 313, and a formation The inner thread 320 of the large inner circumference 317. The cutter portion 33 is located in the small diameter section 312 and has a cutting edge 33 i and a chip flute 332 adjacent to the cutting edge 331. The sliding line 34 is formed on the outer peripheral surface 315 and located at the large diameter section 8 498 311 〇, and the top cover 40 is closed at one end of the large diameter section 311. An outer thread 41 that is screwed to the inner thread 320 of the surrounding wall 31, and a screw hole 42 that communicates with the through hole 32. The connecting rod 50 is screwed in and out of the threaded hole 42 and A threaded section 51 that is screwed with the threaded through hole 42 , a connecting section 52 that can be deviated from the drilled hole 21 , and a receiving hole 53 that extends from the threaded section 51 along the axis L1 toward the connecting section 52 . The jaw blocks 60 are received in the perforations 32 _ slidable along the conical section 9 and respectively have an abutting portion 6 for the push-up surface (4) of the connecting post 5 () Sliding with the conical section 319 - toward the clamping portion 63 of the drill tail 22 and the return springs 70 are respectively located between the two jaw blocks 6 , so that the jaw blocks 60 are in contact with the cone Section 319, and maintains the tendency to slide upwards. When the user uses the cutter holder, first, the user selects a proper diameter drill tail 22' to pass the __ end of the drill tail 22 from the small diameter section 312. Extending into the perforation 32. Then, the remaining connecting portion 转动 is rotated to move the connecting post 50 along the axis L1 toward the inside of the perforation %, and the pushing surface 54 of the connecting post 50 is also The abutting portion μ gradually facing the cool claw blocks 6 () approaches 0. When the pushing surface 54 pushes the abutting portions 61, the sliding portions α simultaneously slide relative to the tapered portion 319, the clips The pawl block 6Q thus moves toward the small setback at the same time, and the central retaining portions 63 in turn clamp the drill tail 1290498 together, and each return spring 70 is thus compressed to store an elastic potential energy. After being combined with the cutter holder, the connecting slave 52 of the connecting post 5〇 is clamped to the drilling device 21, and the drilling device 2 is activated to drive the cutter holder and the drill 22 to rotate. Carry out - (4) work and -, reaming operations. Referring to Figures 4, 5, and 7, when the drilling operation is performed, the drill tail 22 can be drilled into the surface 2 () 1 of the workpiece 200 to produce a bore 2 2 . Since the # reamer portion 33 is located on the seat body 30, when the drill tail 22 is completely staggered into the workpiece 2, the knife 331 of the reamer portion 33 is then performed on the surface 201 of the workpiece. The reaming operation (see Fig. 7) and twisting out a conical shape. 1 Intersection hole 203' and the wood genus generated when the hole is retracted will be discharged from the chip flute 332. When the user wants to replace the drill tail 22, the connecting post 5〇 can be reversely rotated, and the pushing surface 54 is away from the abutting portions 6 and the return spring % also releases the elastic potential energy. The jaw blocks 6 〇 are urged against each other, slide ' away from the small diameter section 312 ' and slide upward along the cone section 319, and the jaw block 6 〇 can thereby loosen the drill tail 22 and The drill tail 22 is removed. Through the above description, the advantages of the present invention can be summarized as follows: First, the 钻海钻尾22 is co-clamped by the jaw blocks 6〇, and the _66 can be pushed by the connecting column 50, The drill tail 22 is then tightened or loosened, and the drill tails 22 of different diameters can also be clamped together by the jaw blocks 6〇. Therefore, the drill collars 22 of different diameters can share the cutter holders. First, when the drill tail 22 is broken, the user can rotate the connecting post 5〇 to move the connecting post 50 along the axis L1 away from the cool claw block 6〇 by 10 1290498. The broken drill tail 22 is detached from the drilling apparatus. Then, the new drill tail 22 is inserted into the perforation 32 from the small diameter section 312, and the connecting post 50 is reversely rotated, so that the drill tail 22 can be tightened to complete the replacement of the drill tail 22, Not only convenient but also fast. Thirdly, if the drill tail 22 is in a __cylindrical shape, the user only needs to tighten the connecting post with respect to the seat body 3, so that the clamping portions 63 of the jaw blocks 6〇 are closely grasped and clamped. By holding the drill tail 22, the drill tail η can be fixed without the relative rotation of the human knife holder. As shown in Fig. i, the drill tail 12 is not required to be machined and cut out as compared with the prior art.
