[Prior Art] In order to improve the security of home security, the advantages and disadvantages of the lock design have a great impact on the anti-theft effect. In the design of the lock, the main axe 5 is eager to make the lock and the key match to achieve better anti-theft performance. In contrast to the various key structures on the market today, although the basic locking requirements can be met, there are still inconveniences. Generally, the key embryo rod must be designed before the key can be created. As shown in Fig. 1, it is Taiwan's announcement No. M334174, "Key embryo rod structure improvement". The key embryo rod mainly has a plurality of surfaces of the rod body u. The guiding groove 12 can be locked by the guiding groove 12 and the lock (not shown). However, the rod body 11 has only a plurality of straight-shaped guide grooves 12 as a structure for cooperating with the lock, and the variability is low, so that the grooves formed inside the lock holes of the lock are relatively monotonous, which may easily cause unscrupulous people. The flat unlocking tool or the key shaft body of similar width is inserted into the corresponding keyhole, so that the lock can be easily opened, and there is a doubt that the anti-theft effect is not good. In addition, the corresponding lock can only be inserted in a single direction, and it is difficult to achieve the function of opening and closing the lock. In practice, the above-mentioned defects still need to be improved. [New content] Therefore, the object of the present invention is to provide a symmetrical key embryo in which a key to be inserted can be inserted into a corresponding lock without a specific direction and structural variability is increased. The new symmetrical lock embryo contains __extension, —, and a cylinder. The extension cup has a rectangular body, and a top member 丨 connected to the body-end, the body has two symmetrical first-extending faces, and two symmetrical and And a second extending surface connected to the first extending surface, each of the first extending surfaces is formed with an extending groove; the cylindrical body is connected to the neck and opposite to the extending rod. The utility model has the advantages that the body of the extension rod has two symmetrical so-called extension surfaces and a second extension surface, so that the whole is symmetrically designed, so that the prepared key can not only be The corresponding lock is inserted in a specific direction - and the month fc· is achieved to facilitate the opening and closing of the lock. In addition, it can also increase the variability of its appearance and has a variety of choices, so that the key can be locked to lock more types of lock structure, not only has the lock can be locked and the anti-theft effect is better. The function also makes the key embryo more versatile. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. As shown in Figures 2 and 3, a preferred embodiment of the novel symmetrical key insert includes an extension rod 2, a neck 31, and a post 33. The extension rod 2 has a rectangular body 21, and a top member 22' connected to the end 21 of the body. The body 21 has two symmetrical symmetry M382359 first extension surfaces 211, and two symmetrical bodies. The second extending surface 212' connected to the first extending surface 2 ι is formed with an extending groove 210 for each surface of the first extending portion 211 (only one of the viewing angles is shown in FIG. 2). As shown in Figures 2 and 4, the neck portion 31 extends from the other end of the body 21 of the extension rod 2 and is opposite to the top member 22; the column 33 connects the neck portion 31 and can be attached to a handle 4 In combination, as shown in FIG. 2, the neck 31 is located between the cylinder 33 and the body 21. As shown in FIG. 5 and FIG. 6, when the user holds the handle 4 to insert the extension rod 2 into a lock 5 that can be opened and closed correspondingly, the lock 5 can be inserted without a specific direction, and As shown in FIG. 7 , after the lock 5 is inserted and positioned, the post 33 is limited to the outside of the lock 5, and the neck 31 is rotated corresponding to the lock hole 50 by rotating the handle 4, thereby interlocking the The extension rod 2 is rotated to achieve the action of locking or opening the lock 5. As shown in FIG. 2 and FIG. 3, the body 21 of the extending rod 2 has two symmetrical first extending surfaces 211 and second extending surfaces 212, and each of the first extending surfaces 211 is formed with a protrusion. The groove 21 is provided, which is advantageous for the structural design of the extension rod 2 to be a grinding hole, that is, the overall change of the key embryo is large, so that the utility model has better usability and safety. In addition, as shown in Fig. 8, the symmetrical key embryo of the present invention can also be processed for the § Xuan extension rod 2 to have more variability in structure, thereby correspondingly opening and closing more types of locks 5 structure. . As shown in the figure, the second extending surface 212 of the body 21 is formed with a guiding groove 35 ′ and the lengths of the guiding grooves 35 are equal (the first extending surface 211 and the second extending direction due to the viewing angle relationship in the figure) The cover 212 and the guide groove 35 are only shown in one), so that the key blank can be extended to the guide groove 35 corresponding to the longitudinal strip-shaped engaging member in the lock 5 to perform the opening and closing operation. Alternatively, as shown in Fig. 9, each of the second extending faces 212 is formed with two spaced apart guide grooves 35, each of which extends from one end adjacent to the neck n to the other end. As shown in FIG. 10 and u, a guide groove 35 and two guide holes 36 are formed on each of the second extending surfaces 212, or a plurality of extending holes 213 are formed on each of the first extending surfaces. The ball-clamping elements in the different types of locks 5 are correspondingly embedded. Of course, as shown in FIG. 12 and FIG. 13 , the guiding holes 36 and the extending holes 213 can also be separately provided. Therefore, the design of the guiding hole 36, the extending hole 213, and the extending groove 21G can be combined with The locks 5 cooperate to achieve the variability of the key embryo structure, so that it has a variety of choices, and the key can be locked to lock more types of lock structures, that is, can be designed to lock Locks with better anti-theft effect and high versatility. In summary, the novel symmetrical key embryo is designed such that the body 21 of the extension rod 2 has two symmetrical first extending surfaces 211 and second extending surfaces 212, so that the whole is symmetric. The design, in turn, allows the formulated key to be inserted into the corresponding lock 5 without a specific direction, and the function of opening and closing the lock 5 can be achieved. In addition, it can also increase the variability of its appearance and has a variety of choices, so that the prepared key can lock the structure of the lock 5 of more types, which not only has the locking function of the matching lock more anti-theft effect. The excellent function, and also makes the key embryo more versatile, so it can achieve the purpose of the present invention. 6 MJ82359 However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is limited by the use of the present invention, that is, the simplicity of the novel application scope and the new description content. Both effect changes and modifications are still covered by this new patent.
