By utilizing the elasticity of the spring 155, the horizontal height of the movable cover 2 can be adjusted to be lowered, so that the mounting frame 5 and the mixing console 51 will be tilted, and the angle of the mixing console 51 will be changed, so that the user can adjust the angle of the mixing console 51 according to his own habits, thereby enhancing the user's experience.

[0045] Two triangular grooves 25 are provided inside the side walls of the movable cover plate 2 adjacent to the fixed cover plate 3, and steering plates 26 are rotatably installed inside the triangular grooves 25. The ends of the two steering plates 26 away from the triangular grooves 25 are rotatably installed between a pair of mounting blocks 154. The two steering plates 26 are arranged in parallel, which facilitates the parallel arrangement of two identical steering plates 26. After the movable cover plate 2 is rotated, the bottom of the movable cover plate 2 can still fit with the surface of the bevel 12 to ensure the stability of the movable cover plate 2.

[0046] When in use, open the buckle handle 311 and directly remove the fixed cover plate 3. Due to the rebound of the spring 155, the movable cover plate 2 will be pushed to slide along the oblique opening 12 to the flat opening 13. Then, the movable cover plate 2 is lifted and rotated to the end of the oblique opening 12. Through the parallel arrangement of the two identical steering plates 26, after the movable cover plate 2 is rotated, the bottom of the movable cover plate 2 can still fit with the surface of the oblique opening 12 to ensure the stability of the movable cover plate 2.

[0047] Then, pull the handle on the mixer 51 upwards, and pull it out together with the mounting frame 5. During the process, the mounting frame 5 first slides out from the inside of the fixing groove 42, and the insertion rod 521 slides inside the guide groove 16. When the insertion rod 521 slides to the inside of the cylindrical hole 161, the limit opening 522 separates from the guide groove 16. Then, rotate the mixer 51 and the mounting frame 5 to make them fall to one side of the movable cover plate 2 until they are in contact with the movable cover plate 2. Then, the mixer can be taken out and placed stably, which is convenient and quick.

[0048] After the mixer 51 is taken out, the baffle 55 just slides into the long slot 23, and in the process of pulling the mixer 51 to move, the gas rod 54 is always in a stretched state, always applying tension to the mounting frame 5;

[0049] When the user is using the device, the movable cover plate 2 can be pushed backwards, so that the steering plate 26 pulls the slider 153 and the mounting block 154 to move to the side away from the flat opening 13, thereby adjusting the position where the stop bar 24 and the anti-slip pad 11 are engaged. During this process, the spring 155 is compressed, and the horizontal height of the movable cover plate 2 is reduced, so that the mounting frame 5 and the mixer 51 will be tilted, and the angle of the mixer 51 will be changed, so that the user can adjust the angle of the mixer 51 according to his own habits, thereby enhancing the user's experience.

[0050] When the mixer 51 is recovered, the drawer 4, the mounting frame 5 and the movable cover 2 are moved to their original positions in sequence, and the fixed cover 3 is fixed to the protective box body 1 by snapping the handle 311. When the mounting frame 5 is put back into the protective box body 1, since the side wall of the baffle 55 away from the circular shaft 52 is in contact with the inner wall of the fixing groove 42 away from the lifting handle 41, the mounting frame 5 can limit the drawer 4, and the lifting handle 41 on the drawer 4 can also be used as a grip of the protective box body 1, thereby increasing the practicality of the protective box.

[0051] By snapping the first clamping strip 21 into the first clamping slot 121, snapping the inserting strip 32 into the second clamping slot 131, and pressing the pressing strip 33 onto the connecting port 22, the movable cover plate 2 and the fixed cover plate 3 can be fixed simultaneously by simply closing the buckle handle 311, which is convenient and quick.
