Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is about a key structure of a hollow lock core, which is mainly designed for the airfoil key used by the hollow lock core. Designed so that when the key is not in use, its lock rod must be fully retracted into the hollow tube section extended by the body, so that its lock rod fins can be hidden without being exposed, so as to give appropriate safety protection performance, Avoid accidentally scratching the edges of the flaps and scratching the human body or objects. ^ [Previous technology] According to 'traditional locks', the inside of the lock core is filled with most lock plates or pins with the same specifications, and the springs of the springs must protrude to one side and obtain a limit with the lock body to prevent the lock from being rotated. According to the design of the type of the key when operating the lock, the lock relationship between the heart and the lock body can be smoothly controlled, so that the structure design of the center can be mainly on the lock lever, and these lock pieces or The pin does not support, so that these lock pieces or pin rods are locked into a limit position, which causes the lock body to maintain its locked state. When the key is used, it must match the shape of the lock piece or pin rod. The pin is disengaged, so that the lock can be rotated to release the lock and the lock can be rotated to achieve the unlocking function. To match this cheek lock, the key flap is designed to correspond to the key of the lock, and the key is inserted into the lock. The continuous lock plate or pin bar of the type of pin or pin is used to release the lock center and the lock body. The lock plate and the lock body are pushed to move the lock center by its toothed fins. , So that the keyband can be 'due to the non-flat, Such quasi-keys based upon its shape sad ground mining vehicle type, and failure of the β indented configuration with its build ^, polished edge for trimming, which results in capacity
