[0028] Please see the appendix Figure 1-5 The purpose of this embodiment is to provide a self-locking bracket with a spring-loaded locking structure, including: a bracket 1 and a cover plate 2. The bracket 1 and the cover plate 2 are self-lockingly connected by a spring-loaded locking structure 3. A mesh bottom 16 is provided at the bottom of the bracket body 11. The top of the spring structure body 31 of the spring-loaded locking structure 3 is provided with a V-shaped locking structure 32; the side wall of the spring structure body 31 is provided with multiple wedge-shaped grooves. In this embodiment, the spring structure body 31 is made of nickel-titanium alloy, and the multiple wedge-shaped grooves can realize the extension and retraction of the spring structure body 31. Preferably, the multiple wedge-shaped grooves are a first wedge-shaped groove 311 and a second wedge-shaped groove 322, and the first wedge-shaped groove 311 and the second wedge-shaped groove 322 face opposite directions.
[0029] Specifically, the bracket body 11 of the bracket 1 is provided with a first wing plate 12 and a second wing plate 13, and a wire groove 15 is formed between the first wing plate and the second wing plate 13. The bracket body 11 is also provided with a clearance groove 14, which is located between the first slide rail 131 and the second slide rail 132 formed on both sides of the second wing plate 13. The cover plate 2 is provided with a first slide bar 22 and a second slide bar 23 on both sides. The first slide bar 22 and the second slide bar 23 are slidably engaged with the first slide rail 131 and the second slide rail 132 respectively, so that the cover plate 2 can move along the bracket 1.
[0030] It should be noted that the bottom of the cover plate 2 is provided with a first V-shaped groove 24 and a second V-shaped groove 25. The axes of the first V-shaped groove 24 and the second V-shaped groove 25 are parallel, and the depths of the first V-shaped groove 24 and the second V-shaped groove 25 are the same. A guide portion 26 is formed between the first V-shaped groove 24 and the second V-shaped groove 25.
[0031] In use, the spring-loaded locking structure 3 is installed in the clearance groove 14. The first slide bar 22 and the second slide bar 23 of the cover plate 2 are inserted into the first slide rail 131 and the second slide rail 132 of the bracket body 11. The V-shaped locking structure 32 located at the top of the spring structure body 31 can enter the first V-shaped groove 24.
