Horizontally arranged on the mounting plate 21 are a pair of fixing columns 22. The inner sides of the outer circumferential surfaces of the pair of fixing columns 22 abut against the middle part of the outer circumference of the lock core housing 13. The above protective component is the lock core housing 13, which can protect the lock core 12, improve the protection performance, fire resistance, and has high safety strength. The fixing columns 22 abut against the corner of the protective component to fix the protective component from being driven by the lock core 12.

[0024] In this preferred embodiment, the outer shell 60 is covered on the outside of the mounting plate 21. Radially arranged at the lower part of the outer shell 60 are several arc-shaped pieces 61. Arranged in a circumferential array at the lower part of the mounting plate 21 are several arc-shaped grooves 62. The several arc-shaped pieces 61 are snapped into the several arc-shaped grooves 62, and the outer shell 60 and the mounting plate 21 are plugged together.

[0025] Furthermore, reinforcing ribs 63 are provided in the middle of the outer shell 60.

The middle shape of the hollow plate is in the shape of an ancient Chinese character. The front parts of the lock core 12 and the protective component are snapped into the through holes in the shape of an ancient Chinese character on the hollow plate. Specifically, the outer shell is made of plastic material and is manufactured by the IML process, with a good-looking appearance and low price.

[0026] The above arc-shaped pieces 61 on the outer shell 60 are snapped into the arc-shaped grooves 62 on the mounting plate 21. The outside of the lock core 12 and the protective component passes through the hollow plate of the outer shell 60, so that the outer shell 60, the password input board 23, the circuit board 26, and the mounting plate 21 are sequentially installed together.

[0027] In this preferred embodiment, the password input board 23 is for button password input. Several numeric buttons 24 and an unlocking button 25 are provided on the password input board 23. Specifically, the password input board 23 can be for touch screen password input.

[0028] In this preferred embodiment, combined Figure 3 , the mechanical and electronic lock further includes a lock core tail rod 14, a dial cam 51, a rod sleeve 41, and a lock tongue 31.
