The button 2 is disposed on the inner wall of the housing 1, a rack 3 is fixedly connected to the surface of the housing 1, the quick-release device 4 is disposed on the inner wall of the housing 1, and a support device 5 is disposed on the surface of the housing 1.

[0021] The following section will explain the specific design and function of its quick-release device 4 and support device 5.

[0022] In this embodiment: the quick-release device 4 includes a baffle 41, which abuts against the inner wall of the outer shell 1. A guide hole is provided on the surface of the baffle 41. A lever 42 is slidably connected to the inner wall of the guide hole on the baffle 41. A sealing plate 43 is fixedly connected to the surface of the lever 42.

[0023] Specifically, a latch 44 is fixedly connected to the surface of the lever 42, and a limit spring 45 is fixedly connected to the surface of the lever 42. An installation groove is provided on the inner wall of the outer casing 1, and a limit bracket 46 is fixedly connected to the inner wall of the outer casing 1 in the installation groove. The lever 42 is provided so that the latch 44 can be moved by the lever 42.

[0024] Specifically, the surface of the baffle 41 has a through hole, the button 2 is slidably connected to the inner wall of the through hole, the toggle block 42 is set through the guide hole, and the sealing plate 43 is slidably connected to the inner wall of the guide hole.

[0025] In this embodiment: a baffle 41 is provided to seal the outer casing 1.

[0026] Specifically, the buckle 44 abuts against the inner wall of the mounting groove, the buckle 44 engages with the inner wall of the limiting bracket 46, and the limiting spring 45 is fixedly connected to the inner wall of the guide hole. The limiting spring 45 is provided to constrain the position of the lever 42.

[0027] In this embodiment: the support device 5 includes a support frame 51, which abuts against the surface of the outer shell 1. The surface of the support frame 51 is provided with a threaded hole, and a positioning bolt 52 is threadedly connected to the inner wall of the threaded hole. A guide sleeve 53 is fixedly connected to the inner wall of the support frame 51.

[0028] In this embodiment: a support frame 51 is provided to support the left connecting frame 54 and the right connecting frame 56.

[0029] Specifically, a left connecting frame 54 is fixedly connected to the surface of the support frame 51, and a retaining strip 55 is fixedly connected to the surface of the left connecting frame 54. A right connecting frame 56 is fixedly connected to the surface of the other support frame 51. The retaining strip 55 is provided so that the two connecting frames can be connected.

[0030] Specifically, there are two support frames 51, which are arranged symmetrically about the outer shell 1. The surface of the outer shell 1 is provided with a fixing groove, and the positioning bolt 52 is threadedly connected to the inner wall of the fixing groove. The left connecting frame 54 abuts against the surface of the rack 3, and the right connecting frame 56 abuts against the surface of the rack 3.

[0032] Working principle: By setting up the quick-release device 4, when using the key, align the key with the lock cylinder and insert it into the lock cylinder. At the same time, the chip matches the lock cylinder's sensing chip, and the key can then be rotated to open the lock cylinder. When the key needs to be disassembled and repaired, move the lever 42. The lever 42 compresses the limiting spring 45. The limiting spring 45 is deformed by compression, and the lever 42 loses the restraint of the limiting spring 45 and moves. The lever 42 pulls the latch 44, and the latch 44 disengages from the limiting frame 46. At the same time, the baffle 41 loses the restraint of the latch 44 and pulls the baffle 41, which disengages from the outer shell 1. The key can then be repaired. By setting up the quick-release device 4, key repair is facilitated, thereby reducing the difficulty of key disassembly, improving the efficiency of key disassembly, and improving the convenience of key repair. In addition, by setting up the support device 5, after the key body is assembled, the support frame 51 supporting the left connecting frame 54 is aligned with the fixing groove of the outer shell 1. Then, the tool is inserted into the positioning bolt 52 and rotated. The tool rotates the positioning bolt 52, and the positioning bolt 52 gradually tightens and fixes the support frame 51. After the left connecting frame 54 is fixed, the right connecting frame 56 is aligned with the locking strip 55 and pushed to the surface of the outer shell 1. Then, the right connecting frame 56 is fixed according to the above steps, which can support the rack 3. By setting up the support device 5, the connection part of the key is more secure, reducing the probability of the key breaking at the connection part and further improving the key's usability.
