Please refer to Fig.10 A guide portion 221 a cooperating with the guide surface 524 is provided at one end of the engaging portion 221 away from the second top plate 42 . The guide portion 221 a is at least partially cylindrical and is used to cooperate with the guide surface 524 for convenient locking.

[0076] Preferably, the button 53 comprises a pressing plate 531, a button seat 532 and a connecting plate 533 connecting the pressing plate 531 and the button seat 532, wherein the button seat 532 is a hollow column, and a through hole matching the profile of the rotating rod 51 is opened in its axial direction. Preferably, a plurality of third reinforcing ribs 533a are arranged at intervals on the connecting plate 533 to prevent the button 53 from breaking. In one embodiment, the pressing plate 531 extends from one end close to the accessory frame 2 and is bent to form a stop plate 531a. When the pressing plate 531 moves from the first pressing position to the second pressing position, the stop plate 531a abuts against the second top plate 42 to limit the rotation position of the rotating rod 51, thereby limiting the rotation position of the lock hook 52, avoiding excessive rotation of the lock hook 52, and further improving the operational stability and product use experience.

[0077] See also Fig.16 , Fig.17 In one embodiment, the bracket 4 is provided with a hinge hole 422a for accommodating the hinge portion 521a. Specifically, the first top plate 22 is connected with two mounting plates 421 arranged opposite to each other, and the mounting plates 421 are provided with hinge holes 422a for accommodating the hinge portion 521a. The bracket 4 is also provided with a receiving groove 423 for accommodating the pressing plate 531 at a position corresponding to the button 53. The hinge portion 521a is passed through the hinge hole 422a, and the pressing plate 531 is located in the receiving groove 423. Preferably, the first top plate 22 is also connected with two parallel first limiting plates 422 located between the two mounting plates 421, and the button seat 532 is connected with two parallel second limiting plates 534 for cooperating with the first limiting plates 422 to limit the position of the button 53 relative to the bracket 4, thereby improving stability.

[0078] In one embodiment, there are two locking hooks 52, which are installed at both ends of the rotating rod 51, and the button 53 is located between the two locking hooks 52. Preferably, the pressing plate 531 and the two locking hooks 52 are evenly arranged on the same side of the rotating rod 51, and two first limiting hooks 511 for limiting the relative positions of the two locking hooks 52 and the rotating rod 51 are respectively formed integrally at both ends of the second rotating plate 51b, and a second limiting hook 512 for limiting the relative positions of the button 53 and the rotating rod 51 is formed integrally in the middle of the second rotating plate 51b. The locking hook seat 521 is recessed from the surface close to the second rotating plate 51b to form a first limiting groove 523, and the button seat 532 is recessed from the surface close to the second rotating plate 51b to form a second limiting groove 535. The first limiting hook 511 and the second limiting hook 512 are respectively clamped in the first limiting groove 523 and the second limiting groove 535, and are respectively used to limit the positions of the locking hook 52 and the button 53 relative to the rotating rod 51, thereby constituting positioning, preventing loosening, and improving connection reliability.

[0079] See also Figures 11 to 13 The lock assembly 5 further includes a reset member 61, which is used to restore the button 53 from the second pressing position to the first pressing position. In one embodiment, the reset member 61 is a spring, one end of which is connected to the lock hook 52, and the other end is connected to the bracket 4. Specifically, the button seat 532 and the second top plate 42 are respectively integrally connected with a first hook 62 and a second hook 63, and the two ends of the reset member 61 are respectively sleeved on the first hook 62 and the second hook 63, so that when there is no external force pressing the button 53, the pressing plate 531 is in the first pressing position by the action of the reset member 61.

[0080] Please continue reading Fig.11 Preferably, when the lock assembly 5 is in the locked state, the angle between the length direction of the reset member 61 and the axial direction of the lock hook arm 526 is 10-60°. Specifically, the lock hook seat 521 and the second top plate 42 are respectively provided with a first limit point and a second limit point for connecting the first hook 62 and the second hook 63, so that the length direction of the reset member 61 and the axial direction of the lock hook arm 526 form an angle range of 10-60°, and the angle between the length direction of the reset member 61 and the axial direction of the lock hook arm 526 is preferably 15-20°. When locking is required, the accessory frame 2 is pushed so that the guide portion 221a slides relative to the guide surface 524, guiding the lock hook 52 to rotate along the axial direction of the rotating rod 51. When the guide portion 221a moves to the clamping surface 525, driven by the elastic force of the reset member 61, the clamping portion 221 abuts against the clamping surface 525, so that the lock assembly 5 and the clamping portion 221 are in the locked state, and the accessory frame 2 is switched to the closed state relative to the bracket 4.
