New description: [New technical field] This creation is about a hollow self-tapping screw, especially for a hollow self-tapping screw that reduces the manufacturing material. [Prior Art] The conventional self-tapping screw is mainly used to fix the mold when grouting _ another-^ and - 疋 position, and the rod of the screw =: = 1 diameter ~ part. After the work is scheduled to be in the position, the power is used, and the tapping end is interlocked by:=, so that the tapping end can be operated by drilling to cause the screw to attack the template. Then, the cap is placed on the threaded portion, whereby the ringing is relative to the template. The above-mentioned conventional self-tapping screw has the following disadvantages, for example, the "structure" is therefore required to consume a relatively large amount of metal material at a higher material cost. Based on the above, it does have a step-by-step improvement to the above self-tapping. Screw. Compliance [new content] The main purpose of this 曰 creation is to provide a hollow self-tapping screw, which utilizes the hollow portion to reduce the material required for manufacturing, and has the effect of reducing material cost. The hollow self-tapping screw comprises a rod body, the surface of the rod body _1 forming a threaded portion and the end of the rod body forms a tapping end, and the other end is formed into a positioning portion; the inside of the rod body forms a middle portion The central portion of the M337009 has a first end and a second end, and the first end is adjacent to the tapping end, and the k end is penetrated to the positioning portion, so that the rod body portion forms a hollow structure. Reduce the cost of materials for manufacturing. [Embodiment] ▲ In order to make the above and other purposes, features, and advantages of this work more obvious, the following is a summary of the best of the following, and with the accompanying drawings, the details are as follows: 曰",,", and Figures 1 and 2, the hollow self-tapping screw of the preferred embodiment of the present invention includes a rod body 1, the outer peripheral surface of the rod body 1 is formed with a thread portion η, and the body 1 is The end is formed - the tapping end 12, and the other end forms a positioning portion 。. The sea tapping end 12 has a knife portion (2) formed on the tapping tooth = the edge of the tapping Person-object; the tM3 system can be selected as a ditch-shaped power tool (not-) connected in the shape of a glyph, a cross or a regular polygon. Also, the main feature of the creation is the inside of the rod i - the hollow portion 14. The hollow portion 14 has a brother 1141 and a second end 142 ′. The first (4) adjacent to the tapping end ^Xuandi two ends 142 penetrates to the positioning portion 13 , thereby greatly reducing the k two-core self-tapping screw Manufacturing material cost. ^Refer to Figures 3 to 5, the hollow self-tapping of the preferred embodiment of the present invention is finer than the H-filled operation towel of the structural building. A wide-ranging purpose is achieved by using the hollow self-tapping of the preferred embodiment of the present invention = the blade portion 121 of the arboring body 1 abuts against the positioning portion 13 of the template 2, via the powered mosquito _ rod 1 t cutter ▼ rotates the rod body 1 so that the # M337009 tooth end 12 (four) 12 敎 the template 2; then, after the template 2 and then through the same actuation mode, the (four) ^ relative The other template 2 is configured such that the rod body 1 passes through the end at the same time, and the nut 3 is screwed to the threaded portion u by the two nuts 3 respectively passing through the tapping end portion 13 . The concrete body of the subsequent reinforced concrete structure can be fixed through the rod body 1 to complete the concrete filling of the subsequent reinforced concrete structure; 0 as described above, the solid structure of the rod body of the screw is compared with the conventional self-tapping _ The utility model has the disadvantages of costly material cost, etc. The present invention in Fig. 2 is provided with the hollow portion 16 inside the rod body 1, so that the rod body i forms a hollow structure, which can actually reduce the material cost. This creation has been disclosed using the preferred embodiment described above, but it is not intended to be used in this creation, any Those skilled in the art will be able to make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention. The scope of protection of this creation is to be attached to the scope of the patent application.
