As shown in Fig. 4, the circular hole saw is composed of a drill bit 4 and a ring saw. The drill bit 40 is further configured as a joint section 41. The middle section of the drill bit 4 is provided with a ring-and-metal joint 50, and the other end section of the drill bit 4 is set as a drilled section 42 for driving in combination with a machine tool. The drilled section 42 extends over the entire equal diameter, and the circumference is formed by a spiral flute and a knife. The % ore 50 is fixed in a concentric manner by a disc 51 concentrically and parallel to the drill bit 4 〇 extending an annular saw blade %, and the end of the saw blade 52 is formed a serrated end 53 , the saw blade 52 and the serrated end 53 form an accommodating space 54 , the saw blade 52 extends in the same direction as the drilled section 42 , and the drilled section 42 is longer than the saw blade 52 and protrudes from the saw blade 52 The serrated end 53 is a section, and the circular saw 51 has a disc 51 and is provided with a chip removing hole 55. The circular hole saw is used for sawing and drilling. The drilled end 42 of the drill bit is used to position and simultaneously drill the wall surface. When the drill bit 4 is drilled into a depth, the saw of the ring saw Deng The sheet 52 then saws a large diameter circular hole in the wall surface with the serrated end 53 until the wall surface between the drill bit 40 and the wrong piece 52 is completely sawed, and the circular waste material 201111073 cut by the saw is in the capacity of the secret 5G. The space is formed, and the wall surface is formed into a large round hole, and the scrap 70 is then ejected from the scrap hole 55 by a ejector pin 55 with a ejector rod. When the waste 70 is ejected out of the 5 〇 accommodation space of the ring mine, some difficulties are actually encountered. The main problem is that the refractory t under the ribs of the New 7G is rubbed, and the contact hole 42 and the scrap hole 7 会 will be rubbed. Toward the temperature, the high temperature causes the bit and the waste center hole to expand at the same time, the bit 40 expands to increase the diameter, the waste 70 expands to reduce the diameter, and the scrap 70 is clamped on the drilled section 42 of the drill bit 4, which is impossible It is easy to push the waste material 7G out of the accommodating space by the ejector pin 55, and it is necessary to wait for the cooling of the drill bit 4 〇 and the waste material 70 to smoothly discharge the waste material 70 out of the accommodating space. SUMMARY OF THE INVENTION The technical problem to be solved is: The round hole of the target is known. During the use process, the keyhole section of the drill bit and the center of the scrap will be affected by the high temperature, so that the secret card is tight in the hole. Paragraph, it is difficult to get out of the current work room 'must wait for the net and waste to cool or use the great strength to get out of the new' how to easily eject the waste at any time, this is the technical problem to solve the technical problem to solve the problem: ^本The invention provides that the improvement system of the round hole county structure includes: - the outline, the end section is set as the joint section, and the other end section is set as the _ section, and the end section of the post is provided with a drilled section, and the drilled section is drilled The outer diameter of the outer diameter of the rafter; and a ring of ore, which is concentrically fixed by a disc and a _t section, the circumference of the disc being concentric and parallel to the bit extending (four) annular, the end is formed with The toothed end 'the saw blade and the 201111073 form an accommodating space in the sawtooth end, the saw blade extends in the same direction as the drilled section and the dodge section is longer than the saw blade and protrudes from the sawtooth end to make the drill The bore segment and the serrated end have a parallel extending spacing. Compared with the prior art, the main improvement of the circular hole saw structure is that the end section of the drill bit is provided with a joint section, the other end section is set as a dodge section, and the drill section is provided at the end section of the dodge section, and the hole is drilled. The outer diameter of the drilled hole of the section is larger than the outer diameter of the dodge of the dodge section. When the drill bit is used in combination with the ring saw, the central hole that can be drilled on the scrap by the drilled section is larger than the doped outer diameter of the dodge section, so that the waste is in the The inside of the circular hole saw is idling, and there is no jamming, so that the waste can be easily taken out. [Embodiment] In order to enable the reviewing committee to have a more in-depth understanding and understanding of the purpose, features and effects of the present invention, the following green g (the figure and the figure number are as follows: First, first by the first As shown in Fig. 2, the round hole ore system includes: the drill bit 10 is again set as the joint section 11, the other end section is set as the dodge section 12, and the end section of the escaping section I2 is provided with the drilled section 13, the drilled section The outer diameter (10) of the drilled hole of 13 is larger than the _section 12 _ avoiding the light 12G, and the end of the age section 13 is further extended with a sharp drilled end 14 'the riding section 11 for the secret of the guarding age, the dodge section 12 is formed with the drilled section 13 and is formed by a spiral chip flute and a cutting edge. And a ring of ore 2G 'fine _ 21 and _ 1G Lang Lang combined and fixed, the disk 21 is concentric and parallel to the class 1 () extends with a ring-shaped a, the end of the secret film 22 is formed with a suture The slab 22 and the miscellaneous end a form a space 201111073, the saw blade 22 extends in the same direction as the drilled section 13, and the dodge section 12 is longer than the slab 22 and extends out of the ore end 23 The segment 'has a distance Η between the drilled section I] and the ore end 23, and the disk 21 of the ring saw is pierced with a chipping hole 25.
