Abstract
The utility model discloses a biswitch internal-tooth key, which comprises a key body and has internal-tooth structures, wherein the internal-tooth structures are arranged on two surfaces of the key body, can be the same or different and can adopt teeth of various shapes; if the internal-tooth structures on the two surfaces are the same, the biswitch internal-tooth key is convenient to insert and pull; particularly, in places with low light intensity at night, the biswitch internal-tooth key is aligned with a lock hole and directly inserted into the lock hole, so that a lock cylinder can be opened; and compared with the conventional external-tooth key, the biswitch internal-tooth key is relatively convenient to use. The problem that the external-tooth key is easy to simulate and copy can be solved. By adopting the external-tooth structure, the external-tooth key is easily and forcibly turned by outer force, and a room door can be opened after the lock cylinder is damaged; the lock hole with the internal-tooth structure is generally square, so that the room door is difficult to open by forcibly turning the internal-tooth key with the outer force, and the lock cylinder cannot be damaged; a high protection function is realized; and a good antitheft effect is achieved.
