With the above structure, by providing the driving inclined surface 341 on the buckle 34, when the button 33 moves vertically, the driving inclined surface 341 of the buckle 34 can be in sliding fit with the upper end of the button 33, facilitating the control of the buckle 34 to move horizontally.

[0075] It should be noted that a guiding inclined surface 332 is provided at the upper end of the button 33, and the guiding inclined surface is in sliding fit with the driving inclined surface 341.

[0076] As shown Figure 9 in the figure, a fixed cover 15 is provided on the outer cover 10, mounting holes are provided at the bottom of the outer cover 10, a limiting boss 331 is provided on the side wall of the button 33, the lower end of the button 33 passes through the mounting hole, the button 33 is erected on the outer cover 10 through the limiting boss 331, the upper end of the button 33 passes upward through the fixed cover 15, the buckle 34 is movably provided above the fixed cover 15, a strip hole 342 is provided on the buckle 34, a fastener passes through the strip hole 342 and is connected to the fixed cover 15, and a first return spring 36 is provided between the buckle 34 and the fixed cover 15. With the above structure, the fixed cover 15 is provided on the outer cover 10. When the limiting boss 331 of the button 33 is erected on the outer cover 10, the fixed cover 15 is installed on the outer cover 10, and the upper end of the button 33 passes upward through the fixed cover 15, so that the button 33 can move vertically between the fixed cover 15 and the outer cover 10. A strip hole 342 is provided on the buckle 34, and the fastener passes through the strip hole 342 in sequence and is connected to the fixed cover 15. In this way, the movement of the buckle 34 is limited by the strip hole 342 and the fastener, and under the action of the first return spring 36, the buckle 34 is always in the cover installation position. When the button 33 drives the buckle 34 to move to overcome the elastic force of the first return spring 36, it is convenient to perform the cover removal operation, and then it is reset under the elastic force of the first return spring 36.

[0077] The disassembly and assembly states of the first embodiment are described as follows:

[0078] The first stage is as shown Figure 13 and Figure 14 in the figure: Before the cover assembly is installed, the cover removal operating member 30 is in the first position L1;

[0079] The second stage is as shown Figure 15 and Figure 16 in the figure: The insertion block 22 of the inner cover 20 of the cover assembly is inserted into the first groove body 111 of the outer cover 10, and the overlapping block 211 of the inner cover 20 is inserted into the second groove body 112 through the avoidance opening 12 on the outer cover 10. Press the button 33 of the cover removal operating member 30 to move the buckle 34 in a direction away from the inner cover 20. At this time, the cover removal operating member 30 is in the second position L2;

[0080] The third stage is as shown Figure 17 and Figure 18As shown: When the overlapping block 211 of the inner cover 20 is at a first distance L3 ≥ 0 in the direction towards the inner lining 14 above the buckle 34, the buckle 34 is reset under the action of the first return spring 36, and the buckle 34 returns to the first position L1. The buckle 34 forms a reverse buckle above the overlapping block 211, and the lower insertion block 22 is matched with the first groove body 111 to form a reverse buckle. Blocked by the first groove body 111, the second groove body 112, the overlapping block 211, and the insertion block 22, the inner cover 20 can only slide in the first groove body 111 and the second groove body 112 of the inner lining 14 and will not fall out;

[0081] The fourth stage is as Figure 19 and Figure 20 shown: Press the button 33, and the button 33 pushes the driving inclined surface 341 on the buckle 34. The buckle 34 retreats backward to the second position L2. When the first horizontal distance L4 ≥ 0, the inner cover 20 blocks and disengages from the buckle position without the buckle 34, and the inner cover 20 is taken out. Release the button 33, and the button 33 is reset under the action of the third return spring 35 of the button. Synchronously, the buckle 34 returns to the first position L1 under the action of the first return spring 36.

At this time, the pull button 37 is in the fourth position L6;

[0088] The third stage Figure 31 and Figure 32 As shown: when the lap block 211 of the inner cover 20 is located above the pull button 37 and the second distance L7 toward the inner lining 14 is greater than or equal to 0, the pull button 37 is reset under the action of the second reset spring 38, and the pull button 37 returns to the third position L5, and the pull button 37 forms a reverse buckle above the lap block 211, and the lower end plug-in block 22 matches with the first slot body 111 and forms a reverse buckle. Under the obstruction of the first slot body 111, the second slot body 112, the lap block 211 and the plug-in block 22, the inner cover 20 can only slide in the first slot body 111 and the second slot body 112 of the inner lining 14 without falling out;

[0089] The fourth stage Figure 33 and Figure 34 As shown: the pull button 37 is pressed, and the pull button 37 is buckled and staggered with the overlap block 211. When the second horizontal distance L8≥0, the inner cover 20 blocks the disengagement position without the pull button 37, and the inner cover can be taken out. After releasing the pull button 37, the pull button 37 is reset to the third position L5 under the action of the second reset spring 38.
