[0028] Please see the appendix Figure 1-5 The purpose of this embodiment is to provide a self-locking bracket with a spring protrusion 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 protrusion 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 protrusion structure 3 is provided with a protrusion structure 32, which has an arc-shaped surface, facilitating movement into or out of the limiting hole while completing the limiting function. Multiple wedge-shaped grooves are provided inward on the side wall of the spring structure body 31. In this embodiment, the spring structure body 31 is made of nickel-titanium alloy, and the multiple wedge-shaped grooves enable 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, with the first wedge-shaped groove 311 and the second wedge-shaped groove 322 facing 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 is worth mentioning that the bottom of the cover plate 2 is provided with an elongated groove 24, the two ends of which are connected to the first limiting hole 241 and the second limiting hole 242, respectively. In this embodiment, the depth of the first limiting hole 241 and the second limiting hole 242 is greater than the depth of the elongated groove 24. The protrusion structure 32 can move from the first limiting hole 241 into the second limiting hole 242 along the elongated groove 24.

[0031] In use, the spring protrusion structure 3 is installed in the clearance groove 14, and 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 protrusion structure 32 located on the top of the spring structure body 31 can enter the first limiting hole 241. Continuing to push the cover plate 2, the spring protrusion structure 3 retracts, and after sliding and engaging with the elongated slide groove 24, the spring protrusion structure 3 enters the second limiting hole 242. The spring protrusion structure 3 resets, and the protrusion structure 32 enters the second limiting hole 242 for limitation, thereby closing the bowwire groove 15. The self-locking bracket 1 and the cover plate 2 are self-lockingly connected by a spring protrusion structure 3. The top of the spring structure body 31 of the spring protrusion structure 3 is provided with a protrusion structure 32. By pulling the cover plate 2, the cover plate 2 can be moved on the bracket 1 and self-locked and limited. The protrusion structure 32 can extend into the first limiting hole 241 or the second limiting hole 242. The structure is simple and easy to use.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
