New description: 【New technical field】 This creation department provides a kind of fast core-retaining iron, which is mainly used in the fast-remaining core-removing technology of the size of the evening. It is matched with the body of the ship and the small drill bit of A. [Prior Art] _Press 'Please refer to the figure - Figure: Stereoscopic diagram of the system. As shown in the figure y, the front view is a plan view. The traditional core-drilling 1 is thin and thin, and it is difficult to size and the hole. It is a size 1 specification, and it can produce a variety of cored core drills. The manufacturing cost and processing cost are τ% and the cutting edge 2 is The shape of the triangle is as high as 14 mm. When drilling, the resistance is large and the material is wasted. It is one of the problems and defects that the domain is still seeking to overcome and solve. In addition, the traditionally used core-drilling drill has only four cutting edges, the processing feed rate is slow, the time is long, the cutting edge wears quickly, and the amount of iron filings is large, which is the second problem that is both solved and solved. At the same time, the traditionally used core-drilling drills have a large straight-type friction area, which is not conducive to leakage, and it is still to be sought to overcome the three problems. [New content] In view of this, this creative personality is actively investing in the spirit of research and development and innovation, and finally completed the creation, is to provide an improved fast core drill. The new technical solution to solve the problem and the efficacy of the previous technology 4 M342222 lies in the fact that the rapid core-drilling of this creation is made by the main body, the pipe body and the drill bit being screwed together, and the drill bit can be processed according to the machining aperture. The size can be changed, the body can be replaced according to the length of the hole to be processed. One body can be applied to various sizes of the pipe body and the drill bit, which has the functions of saving materials, cost and processing, and has the effect of improving the efficiency. The winner. The technical means of applying the new problem solving 2 and the efficacy of the prior art are as follows: the rapid core drill of the present invention has ten cutting edges, the processing feed speed is fast, the processing time is shortened, and the wear of the cutting edge is ten. Distribute and slow down each other, and reduce the amount of iron filings by a third, with an increase in efficiency, reaching for its secondary purpose. The technical means of applying the new problem solving three and the efficacy of the prior art are as follows: the thickness of the drill bit of the present invention is 2.5 mm, the thickness of the drill edge is 3.5 mm, and the resistance is small when drilling. The cutting edge has a pointed cone shape, a small friction area, and is advantageous for chip removal, and has an improvement in efficiency, and is achieved for another purpose. [Embodiment] In order to make the person who is familiar with the generalization of the art know the structure of the creation and the functional benefits that can be achieved, a specific embodiment is listed, and the detailed description is as follows: Kind of fast core drills' Please refer to the third and fourth figures: the three-dimensional combination and decomposition diagram of this creation. As shown in the fifth figure: the front view of the creation. It is mainly composed of three parts: main body 1G, pipe body 20, and drill bit 3〇; among them: main body 10 is provided with _ teeth i丨 (may be 5 M342222 teeth with multiple teeth). The body 10 is screwed into the body, and the center of the body 10 is filled with cooling water; the body 20 is provided with an external thread 2 corresponding to the inner thread 11 of the main body 1 (may be a plurality of teeth) Outside the mouth, the internal thread 11 is screwed into one body, and the other end of the body 2 is provided with internal thread 2 2 (can be a tooth with multiple teeth) ), thereby being screwed into a single body with the drill bit 3; the drill bit 30 corresponds to the inner thread of the tubular body 20, and the external thread 31 is provided (which can be a tooth having a plurality of teeth). The other end of the drill bit 3 is evenly distributed with a plurality of grooves 3 2 as a plurality of drills 3 3 embedded therein, and each of the grooves 32 is provided with a notch 34 at the bottom thereof as a spring-loaded drill blade 3 3 For the purpose, the thickness of the drill bit 30 is about 2.5 mm, the thickness of the drill edge 3 3 is about 3.5 mm, and the cutting edge 3 3 has a tapered shape, which can reduce the friction area 'cooperating with the cooling of the center 1 〇 center injection. Water, there is In the chip. The combination of the above-mentioned components is a kind of fast core-retaining drill. For practical application, please refer to the sixth figure: The schematic diagram of the cross-section of the creation. The user can change the appropriate body 2 〇 and the drill bit 30 in the main body 2 依照 according to the size and depth of the hole to be processed. The user only needs to prepare a main body i 〇 that can apply a variety of specifications of the body 20 Drill bit 30 is quite economical and convenient to use. Based on the above, the creation department provides a fast core drill. After the actual production of the creator and the repeated operation test, it is confirmed that the functional benefits expected by the creation can be achieved, and at the same time, there is no such thing as the current experience. First of all, it has the "utility value of the industry". It is true that M342222 has applied for the new patents in accordance with the provisions of the Patent Law in accordance with the establishment of the "patentability" and "progressiveness" of the new patents.
