New description: [New technical field] This creation is to provide a kind of cement bolt, especially a structural improvement of cement bolt which is easy to lock and easy to manufacture and more stable in the locking process (1). [Prior Art] According to the conventional cement bolt, only the spiral thread is provided on the body, and the screw angle makes the cement bolts perform poorly in the locking and unloading performance, and the performance on the fixing is also not strong. And the state of use is not easy to remove after locking, so because of its fragile structure and material, it is easy to break during construction, resulting in inconvenient construction and danger. In addition, due to the poor balance of cement bolts, it is not easy to maintain vertical locking when it is locked. However, when the above-mentioned conventional cement bolts are used, the following problems and defects are still to be improved: 1. It is not easy to use the cement bolt thread angle and its material to cause the lock or the removal. Second, the conventional cement bolt balance effect is not good, when it is fixed, it is not easy to maintain vertical locking. Therefore, how to solve the problems and shortcomings of the above-mentioned practices, that is, the creators of the creation and the relevant manufacturers engaged in the industry are eager to study the direction of improvement. [New Content] M418987 Therefore, the creators of this creation, in view of the above-mentioned deficiencies, collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed this. Structural improvement of cement bolts that are easy to lock and easy to manufacture and more stable in the locking process (1) New patents. The main purpose of this creation is to break through the problem of the screw angle of the conventional cement bolt and the material that causes the locking or removal to be easy, and to achieve practical and easy to lock and easy to manufacture. In order to achieve the above purpose, the present invention relates to a structural improvement of a cement bolt (1), comprising: a rod body, a first thread and a plurality of cutting threads, the top end of the rod body defining a head for locking, and the bottom end of the rod body Determining a contact portion, the first thread is defined on the rod body, and the first thread is extended from the head to the end of the contact portion at a helix angle of between 16 and 23 degrees, and above the first thread The fascia and the rod define the first angle of the teeth, and the first angle is between 90 degrees and 1200 degrees. This angle is easy to manufacture, and the pitch of the first thread is between 5 mm and 2 ◦. PCT, each cutting thread is distributed on the first thread and adjacent to the contact end, and the depth of each cutting thread is equal to the distance from the top of the first screw to the rod body, and the above design is easy to lock and remove. The second purpose of this creation is: for the purpose of the use of cement 4 M418987, the fifth and sixth figures are the three-dimensional intent and partial enlargement of another preferred embodiment of the present invention, which can be clearly seen from the figure. The structure of the embodiment is substantially the same as that of the preferred embodiment, except that the rod body 1 forms a second thread 13 between the head 10 and the contact portion 1 1 , and the second The thread 13 is lower than the first thread 12, and the angle F between the upper edge and the lower edge of the second thread 13 is between 40 degrees and 47 degrees, with the second thread 1 3 can be guided when locking and make the locking process more stable. However, the above description is only a preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention. Therefore, all the simple modifications and equivalent structural changes using the present specification and the schema should be the same. It is included in the scope of this creation patent and is given to Chen Ming. Therefore, please refer to all the figures. When using this design, compared with the conventional technology, the following advantages exist: 1. The first angle A is between 90 degrees and 120 degrees, which is easy to lock and remove. It has the advantage of convenient and labor saving when locking. Second, the cutting thread 1 2 1 can increase the sharpness and reduce the friction when locking, which is convenient for cutting and locking. Third, it is easier to use cement bolts in processing, so the steps and technology are more economical. Fourth, the creation department is heat-treated, so in addition to its solid structure, the material is more durable and can achieve the effect of repeating 7 M418987. 5. The second screw 13 can be used for guiding when locking and making the locking process more stable. In summary, the structural improvement of the cement bolt of this creation (1) in the use, in order to achieve its efficacy and purpose, the creation is a practical and excellent creation, in order to meet the requirements of the new patent application, To file an application, I hope that the trial committee will grant this creation as early as possible to protect the creators' hard work. If there is any doubt in the ruling committee, please do not hesitate to give instructions, the creators will try their best to cooperate and feel good. 8 M418987 BRIEF DESCRIPTION OF THE DRAWINGS The first figure is a perspective view of a preferred embodiment of the present invention.
