[0041] In this embodiment, for example, the lock cylinder 1 is a metal part; the first lock groove 101 penetrates the lock cylinder, and the inner ring diameter of the second lock groove 103 is larger than the diameter of the first lock groove 101.

[0042] For key component 2, the specific design is as follows:

[0043] The upper end of the key piece 2 is provided with a lock cylinder 3 that is adapted to the second lock groove 103. The outer ring wall and / or the outer ring wall are provided with a protruding structure 4 along the axial direction. When the lock cylinder 3 is inserted into the second lock groove 103, the protruding structures 4 provided on the lock cylinder 3 can be inserted into the groove structure 104 provided in the second lock groove 103 one by one.

[0044] The lower end of the key component 2 is provided with a lock head 5, which is used to cooperate with auxiliary tools to make the key component 2 rotate.

[0045] In this embodiment, for example, the key component 2 is a metal component; the lock head 5 has a square cross-section.

[0046] Preferably, the lower end of the inner ring groove wall of the second lock groove 103 is provided with a first chamfer structure 105 to facilitate the insertion of the lock cylinder 3 into the second lock groove 103.

[0047] More preferably, each of the protruding structures 4 on the lock cylinder 3 has a second chamfer structure 401 at its upper end, so as to facilitate the insertion of the protruding structure 4 on the lock cylinder 3 into the groove structure 104 in the second lock groove 103.

[0048] Preferably, the lower end face of the lock cylinder 1 is provided with an upwardly extending guide groove 106, the diameter of which is larger than the outer ring diameter of the second lock groove 103. In use, the lock cylinder 1 is generally in a vertical position with its second lock groove 103 facing downwards. In this case, the lock cylinder 3 of the key 2 can be inserted into the guide groove 106 first, and then, following the guide groove 106, the lock cylinder 3 of the key 2 can be quickly inserted into the second lock groove 103 (rotation is required). In other words, the guide groove 106 serves as a pre-guide.

[0049] In the above technical solution, the groove structure 104 is an arc-shaped groove, the protrusion structure 4 is an arc-shaped protrusion, three groove structures 104 are evenly provided along the circumference on the outer ring wall of the second locking groove 103, and three protrusion structures 4 are evenly provided along the circumference on the outer ring wall of the locking cylinder 3.
