[0034] In this embodiment, the base 1 is configured to be composed of two parts, namely, a base plate 11 and a lock core bracket 12. The lock core bracket 12 is disposed on the base plate 11, and the lock core 3 is clamped between the base plate 11 and the lock core bracket 12, thereby enabling the lock core 3 to be stably clamped and installed, thereby preventing the lock core 3 from moving or shaking. Secondly, a first insertion hole 111 is formed on the base plate 11, and a second insertion hole 121 is formed on the lock core bracket 12. The first insertion hole 111, the lock hole 30, and the second insertion hole 121 are relatively disposed. The arrangement of the first insertion hole 111 and the second insertion hole 121 can play a good role in inserting and guiding. In addition, the present disclosure does not limit the specific structure of the base 1, and it can be constructed in any appropriate shape and structure.
[0035] Optionally, refer to Figures 2 to 4 As shown, the base plate 11 defines a mounting groove 110, the first insertion hole 111 is communicated with the mounting groove 110, the lock core bracket 12 is disposed in the mounting groove 110 and connected to the base plate 11, and the lock core 3 is disposed in the mounting groove 110 and clamped between the base plate 11 and the lock core bracket 12. By providing the mounting groove 110, and the lock core 3 being disposed in the mounting groove 110 and clamped between the base plate 11 and the lock core bracket 12, the lock core 3 can be effectively protected to avoid damage to the lock core 3.
[0036] In other embodiments, referring to Figures 2 to 5 As shown, the mounting groove 110 is recessed along the second direction B and is formed with an open opening 1100, and a first insertion hole 111 is formed on the bottom wall of the mounting groove 110; the lock core bracket 12 includes a bracket plate 122 and a bracket sleeve 123, the bracket sleeve 123 is connected to the bracket plate 122, and the bracket sleeve 123 and the bracket plate 122 define a bracket groove 120; the bracket plate 122 is sealed at the open opening 1100, and a second insertion hole 121 is formed on the bracket plate 122 and is connected to the bracket groove 120; the lock core seat 31 is clamped between the bracket sleeve 123 and the bottom wall of the mounting groove 110, and the lock core spring piece 32 is arranged in the bracket groove 120.
[0037] In this embodiment, the above-mentioned installation groove 110 can be constructed into any appropriate shape, and the present disclosure does not limit this. The present disclosure also does not limit the molding method of the installation groove 110. For example, it can be injection molding or machining molding.

The tapered configuration of the lock bar plug 22 facilitates insertion into the lock hole 30, improving the convenience of insertion. However, the flexible lock bar 2 can be constructed in any shape, and the present disclosure is not limited to this.
[0042] In terms of material selection, the flexible lock strip 2 can be made of plastic material, and the lock core spring piece 32 can be made of metal material; wherein, the flexible lock strip 2 and the lock core spring piece 32 are interference fit, thereby improving the strength of locking the flexible lock strip 2. The lock core spring piece 32 made of metal material has sufficient strength and rigidity, effectively preventing the lock core spring piece 32 from breaking during use, thereby extending the service life.
[0043] In addition, the lock core bracket 12 can be integrally formed of metal material, and the lock core seat 31 and multiple lock core spring pieces 32 can be integrally formed of metal material, thereby improving the strength of the lock core bracket 12 and the lock core 3 and extending their service life.
