Usually, the drill bit can prevent the drill bit from being electrically applied to the outer end surface of the drill bit to form a lost motion structure. However, it is still related to the twist point on a keyhole surface to a drill with a special drill bit positioning drill. The state of rotation will not be affected by a kind of lock. The lock core is provided with a hard and hard concave hole to cover the head. Excessive damage mill, but in terms of damaged anti-drilling structure. A bump, the material of the anti-drilling cover, and the inner shaft body when the drill is forcibly drilled, the anti-drilling piece is damaged, so that the anti-drilling piece is located in the anti-drilling piece and has anti-theft, especially the inner piece. The effect of deep-breaking steel drill bits that can be broken by the outer end of the card cooperation is a kind of operation on the outer end of the shaft body of the lock core, which is used outside the inner shaft body to prevent the surface. At that time, the main structure of the electric drill that could create the basic shaft of the electric drill along with the electric drill's basic structure was that a non-circular keyhole was provided inside the inner shaft of the lock core, and the opening of the keyhole was It is exposed on the outer surface of the inner shaft ^ This key hole is used to insert the paired key into the inner shaft. At least one bump is provided on the outer end surface of the inner shaft body. And, an outer end surface of the inner shaft body is covered with an anti-drilling piece, which is made of a special steel hard metal material or a special hardened metal material. And the drill prevention piece itself is provided with a through hole, and the through hole is in a state corresponding to each other with the keyhole of the inner shaft body. Therefore, the through hole is also a non-circular shape. That is, when the anti-drilling piece is covered on the outer end surface of the inner shaft body, the convex point on the outer end surface of the inner shaft can be snapped to the edge position of the through hole of the anti-drilling piece, so that the anti-drilling piece has the positioning effect. . Therefore, the through hole of the anti-drilling piece and the key hole of the inner shaft body correspond to each other, so that the key can be easily accessed by the key.

And when the drill bit is damaged by the drill bit of the electric drill, the through hole of the drill bit can damage and wear the bumps on the outer end surface of the inner shaft, so that the drill bit can become idle with the drill bit of the electric drill. Therefore, the deep braking structure of the shaft body in the lock core will not be damaged, and the entire lock will not be stolen. [Previous technology] Press, due to the rapid advancement in the manufacturing technology of hand tools and equipment, the functions of hand tool products are becoming more and more sophisticated, especially portable electric appliances with charging function: tools are more powerful, and are being carried. Both aspects and usage are not convenient. So today's Xiaoxiao thief is using the power of this portable electric hand tool and its easy-to-use features as its theft-. For example, today's thieves carry convenient ^ electric drills to break the lock core, and can unlock the locks for the purpose of stealing. For this reason, how to effectively prevent thieves from benefiting W and stopping f, so β I j uses electric drills to destroy theft and unlock locks? This is one of the most important professional issues that lock operators must face. According to the prior art, for example, in our country's patent for a patented "excellent structure for rowing locks," its face number is made of-minus the heart shell and there are several rows inside it. There are locks inside, and the key hole of the row row is locked. There are at least two kinds of shapes ;: The shape of the iron keyholes of the layer-by-layer pieces is the same shape as the two d of the rectangle, which is the shape of the keyhole that is deep and the surface layer ^ is the shape of the concave shape of the rectangular furnace. The shape of the insertion rod of the key code is provided with two different sections of the shape of a curved outer concave shape. The front section is inserted with CHALP040Lptd Page 6 M253658 4. Creation instructions (3) The two sides of the rod are provided with arc bulges. Protruding closed function. The core shell and its inner end face are covered with a block, but it is checked that the protective sheet attached to the lock core is designed with a special hardened structure to treat the bad. However, with the flexible rotation, the drill's protective sheet must be easy for the key to enter and exit. The diameter of the round hole on the longest side of the conventional protective keyhole appears to be that the drill is made from the protective sheet and theft is not completely effective. [New content] This creative feature The recessed grooves' can be used to communicate with each other. It is provided with a number of rows that can be flexibly rotated to protect the lock. The metal sheet protects the lock core. , So that the drill bit does not match the key piece of the lock core, the key piece must be in its round hole structure. Slightly larger than the center round hole unlocking device. Yes, the anti-theft channel is reached, and the two sides of the rear section of the insertion rods are matched and matched to achieve a lock core, a lock plate and a spacer formed in the housing, and a protective plate in turn, which protects the core from being damaged by external forces. The end face of the improved structure of the row lock is covered with a piece made of special steel and hard metal. The structure of such a part is not easy to be protected by the structure of the protective sheet. The protective sheet must not only be able to destroy the shape of the keyhole with the power point of the electric drill, but also cannot be damaged. Therefore, based on such a central position, a straight line is provided, but also because it is preventive, so that a thief can drill into it, thereby destroying the effectiveness of the lock before the aforementioned patent. The arc-shaped lock is provided, and the heart is locked by the outer side of a lock core shell. In the structure, the material can be flexibly rotated or the electric drill drilled through the protective sheet is broken to protect the drill bit. Moreover, by design, the conditions limit the diameter slightly larger than the center of the key guard using the electric drill inside the structural design. Do n’t target the lock core structure, which is easy for a thief to use a power drill to force it.
