Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figures 1 to 7 The unidirectional transmission lock box 2 shown includes a mounting panel 1 and a lock box 2. An incomplete gear 3 is located in the center of the lock box 2, and a gear rack 11 is located in the center of the mounting panel 1. The incomplete gear 3 and the gear rack 11 are in clearance fit. Slide rails 12 are provided on both sides of the mounting panel 1 for relative sliding of the lock box 2. Fixed slots 21 are provided on both sides of the bottom of the lock box 2, and several locking blocks 22 are provided within the fixed slots 21. The lock box 2 is slidably connected to the slide rails 12 via the locking blocks 22. Through the interaction between the locking blocks 22 in the fixed slots 21 at the bottom of the lock box 2 and the slide rails 12 of the mounting panel 1, the lock box 2 slides relative to the mounting panel 1 by rotating the incomplete gear 3, causing the incomplete gear 3 to contact the gear rack 11. This effectively increases the adjustment distance of the lock box 2 relative to the mounting panel 1, while also simplifying the structure and making the unidirectional transmission lock box 2 more compact, suitable for various scenarios.

[0033] The locking block 22 has a V-shaped groove 221 on the side near the slide rail 12, and a locking block 222 perpendicular to the V-shaped groove 221 on the side away from the slide rail 12. A locking hole 211 for accommodating the locking block 222 is provided in the fixing groove 21. The locking block 22 is fixedly connected to the lock box 2 by placing the locking block 222 into the locking hole 211. The V-shaped groove fits well with the slide rail 12 on the mounting panel 1, allowing the lock box 2 to slide smoothly against the mounting panel 1. Furthermore, the locking block 22 is fixed in the locking hole 211 on the fixing groove 21 by the locking block 222, thus securing the locking block 22 within the lock box 2 and effectively preventing the locking block 22 from falling off and causing instability in the sliding of the lock box 2.

[0034] The lock box 2 is divided into a front lock box 23 and a back lock box 24. The back lock box 24 has a second fixing hole 241 on its surface, and the front lock box 23 has a first fixing hole 231 on its surface.
