New description: [New technical field] This creation is about the improvement of the structure of foaming wood knives for training and teaching, especially a round bar with a sharp edge material, and then a round bar made of two different density foams. The coating is integrated to protect the body and prevent breakage when the grip is hit. [Prior Art] According to the conventional wooden sword, the system is made of wood by grinding and cutting into a simulation _ the real sword type (see the first figure). There is a grip under the wooden sword. The front upper part is provided with a blade body a2, and the grip a1 and the blade body a2 are provided with a partition a3. However, the grip of the utility item provides the part held by the user, and the grip a is separated from the blade body a2 by the partition. Since the wooden sword is a wooden product, the user needs to practice or play frequently. If the player wants to knock down the opponent or practice f when playing too hard, it will be very painful to be hit by the wooden sword, which is easy to cause personal injury. It is also easy to cause the break of the wooden sword. In recent years, some workers have covered a foam material a4 in the outer part of the wooden sword, but it is still inevitable to avoid personal injury and the break of the wooden sword. The coated blade a2 is still made of wood and has no bouncing effect, so it is necessary to improve it. [New content] The creator of this case has the lack of the wooden knife structure of the above-mentioned training and teaching. The research of Mai carefully and the individual's involvement in the matter _ years of experience, the final design - the new salary of the training teaching foam wood knife Structural improvement." The main purpose of this creation is to provide a structure for recording, organizing, and arranging cotton knives. When using M297779 for training, it can achieve the effect of _ others' body and not easy to break. In order to achieve the above objectives, the creation of the "Improvement of the structure of the foaming wood knife for training and teaching" is mainly composed of a blade body and a grip; the outline is that the blade body is covered by two kinds of non-domain foams, and the inside thereof is The core is a kind of poplar material f, the first foam layer is a foam material with a higher density, and the side thereof is provided with an opening, and the opening is provided with a foam body, which is arranged outside the round bar, The second foam layer is made of a second cotton material having a lower density, and each of the front and rear ends has an opening that is disposed on the outer side of the first foam body. [Embodiment] The structure, the device and its characteristics of the creation - the feasible embodiment of the creation and the detailed description of the figure are as follows: Please match the second picture, the "training teaching (four) cotton wood knife structure improvement" of the creation, The main body is composed of a blade 1 〇 and a grip 2 ;; wherein the blade 1G is a combination of two different materials of foam, which is a kind of round bar 11 with a sharp edge material, the round bar n can be a kind of glass fiber material f, the first foam layer 12 is a foam material with two twists, the foam material can be an eva material, and the abbreviation of the ethylene-vinyl acetate copolymer ( The acetate copolymer has an opening 121, and the opening i2i is provided with a foam body 122'. The foam body 122 is made of the same material as the first foam layer 12, and the first foam layer 12 is wrapped. Covering the outer side of the round bar n, the second foam layer U is made of a foam material having a lower density, and each of the front and rear ends has an opening 131. The second foam layer 13 can be a rubber foam material coated on the same. The outer side of the first foam body 12. M297779 Please match the second, third and fourth figures. When the combination is created, the first foam layer is assembled from the open Πm, and then the body is folded into a body, and then the foam body 22 is inserted into the p At the opening 121 of the cotton layer u, and the first foam layer 12 will cover the round bar, and the opening faces the side of the blade body 10, and finally the second foam layer η will be combined by the opening 13i. The first foam layer 12 and the round bar u are inserted into the body to be integrated.

No matter how the curved wooden knife is bent, the material f is not easy to break. Even if the structure changes, it does not affect the use of force, even if it is. The traces of the P-like will not break, that is, _ to the other party, the other party will not be subjected to any damage; and the way of waving the foamed wood T-way is to swing the upper and lower layers of the first foam layer 12 On the side of the blade, it is not easy to make the scales fall out, and the force points of the foam wood knife can be dispersed, so that the phenomenon of damage and breakage can be reduced. In summary, the 'Improvement of the structure of the foaming wooden knife for improving training and teaching” can achieve the effect of protecting the body and not easily broken, and the creation of "practical!
