To prevent damage such as crushing and cracks that occur when the bent key piece passes through the key passage It is an object of the present invention to provide a functioning lock and key structure.    [0004]  [Means for solving the problem]   In order to solve the above-mentioned problem, the present invention provides a lockable key and key structure mainly including an outer cylinder, It consists of an upper, lower inner cylinder and a key, and the outer cylinder is provided with an inner cylinder installation hole. There are several tumbler holes that penetrate the inner cylinder installation hole in the And the lower inner cylinder are combined into the inner cylinder installation hole of the outer cylinder. The curved and opposing key passages are installed, and the upper inner cylinder upper part is in the tumbler hole of the outer cylinder. In contrast, a tumbler hole with a pin tumbler and spring has been opened. A keyhole is installed at one end of the lower inner hole, and a spring is installed at an appropriate position on that end. A groove is provided, and a hole leading to the key passage is made in the installation groove, and the spring protrudes into that hole. The key is composed of a bent key piece, a key cover and a handle. The foldable key piece is installed inside the key cover and combined with the handle, A long slide hole is installed on the inner surface of the cover, and a fixing groove is provided in front of the key cover. Is provided to correspond to the projection of the spring installed on the lower inner cylinder, and the lock is unlocked. When the front end of the key is inserted into the keyhole, the protrusion of the key cover Into the fixing groove, fix the key quickly, the bent key piece smoothly enters the key passage Then, the structure of the lock and the key that can be unlocked and lockable.   [0005]  [Embodiment of the invention]   Hereinafter, specific technical contents of one embodiment of the present invention will be described with reference to the drawings.   First, as shown in FIG. 1, the structure of the lock and key which can be fixed according to the present invention mainly comprises the outer cylinder 1, It comprises an inner cylinder 2, a lower inner cylinder 3, and a key 5. Outer cylinder 1 is inner cylinder installation hole 1 0 penetrates the front and rear, and several tumbler holes 11 are provided in the upper part The upper inner cylinder 2 and the lower inner cylinder 3 are combined and It is installed in the cylinder installation hole. The upper and lower inner cylinders 2 and 3 are curved and opposed to each other. Key passages 20 and 30 are provided, and the upper inner cylinder 20 is provided in the tumbler hole 11 of the outer cylinder 11. A tumbler hole 20 in which a pin tumbler 21 and a spring 22 are embedded. 0 is installed, and a keyhole 31 is installed at one end of the lower inner cylinder 3 and installed at that end. A groove 320 is provided, and a hole 320 leading to the key passage 30 is formed in the installation groove 32. A spring 4 having a projection 40 that protrudes into the hole 320 is provided.  [0006]   The key 5 includes a bent key piece 50, a key cover 51, and a handle 52. The bent key piece 50 enters the key cover 51 and is combined with the handle 52. By pressing or pulling the handle 52, the bent type key piece accompanying it is It is taken in and out of the key cover 51. Also, slide on the inner surface of the key cover 51. A long hole 510 is provided, and a fixing groove 511 is provided on one side in front of the key cover. The fixing grooves 511 correspond to the protrusions 40 of the spring 4. [0007]   As shown in FIG. 2, when unlocking, the front end of the key cover 51 of the key 5 is inserted into the keyhole 31. Just by inserting the protrusion into the fixing groove 511 at the front end of the key cover 51 by the elasticity of the spring Then, the lock and the key 5 are quickly fixed. Next, when the handle 52 is pressed, the bent key piece 50 is Smoothly enter along key passages 20 and 30, pin tumbler 21 and spring Then, the key 22 is pushed up, and the key 5 is further turned to move the upper and lower inner cylinders 2 and 3 to unlock.
