As mentioned above, the back plate 2 is provided with the strip-shaped through hole 201, and for the clamping column 5, the clamping column 5 can pass through at will, but the rotating buckle plate 6 cannot pass through at will. Specifically, only after the rotation of the rotation plate 6 in the circumferential direction by a certain angle, the outer shape profile of the rotation plate can pass through the opening range of the strip-shaped through hole 201. For example, the strip-shaped through hole 201 and the rotary buckle plate 6 are rectangular integrally, so that the rotary buckle plate 6 can pass through only when rotating to the length direction which is parallel to the length direction of the strip-shaped through hole 201, and the rotary buckle plate 6 buckles the bottom surface of the back plate 2 at other angles. And, the rotation angle of predetermineeing of spinner plate 6 is relevant with the concrete shape of bar through-hole 201, for example when bar through-hole 201 is the rectangle, spinner plate 6 at first rotates 90 to the long limit is perpendicular with the long limit of bar through-hole 201, and the lock is at this moment, and is unable current, and after 90 is rotated to the syntropy again, the length of spinner plate 6 is parallel with the long limit of bar through-hole 201, breaks away from this moment, can pass. Meanwhile, the preset rotation angle of the spinning plate 6 is also related to the number of the guide rails 102, for example, when the preset rotation angle is 90 degrees, the number of the guide rails 102 is 360 degrees/90 degrees and is 4. Similarly, if the strip-shaped through hole 201 is cross-shaped, the rotating buckle plate 6 can be buckled by rotating 45 degrees at first and then can be separated by rotating 45 degrees, and at this time, the number of the guide rails 102 is 360 degrees/45 degrees, and is 8.
As shown in fig. 6, 7 and 8, fig. 6 is a schematic view and a sectional view of an initial state when the quick fastening member is not pressed, fig. 7 is a schematic view of a state when the quick fastening member is pressed for the first time until the rotating disk is separated from the guide rail, and fig. 8 is a schematic view of a state when the rotating disk is combined with the pressing column after the pressing is finished and the hand is released.
So, when the installation between backshell 1 and backplate 2 needs to be realized, can at first with revolving buckle board 6 back-off on the bottom surface of backplate 2, and hold it, then will press post 3 and insert in the mounting hole 101 on backshell 1 together with rotary disk 4 and joint post 5, and make joint post 5 pass through behind the bar through-hole 201 and form the joint with revolving buckle board 6, press post 3 and rotary disk 4 all to be in the length range of guide rail 102 this moment, and press the spout of seting up on the circumference of post 3 and rotary disk 4 all with the guide rail 102 cooperation that corresponds, tensioning spring 7's bottom can with backshell 1 surface looks butt simultaneously, but not compressed yet.
then, the top of the pressing column 3 can be pressed with force, the pressing column 3 is pushed to descend downwards together with the rotating disc 4 until the bottom surface of the pressing column 3 reaches the end position of the guide rail 102, at this time, the sliding groove on the rotating disc 4 is separated from the guide rail 102, the top column 303 at the bottom of the pressing column 3 abuts against the arc-shaped surface 411 of the wedge block 401 on the rotating disc 4, and the tension spring 7 is compressed to a certain extent in the process.
Next, the pressing column 3 is continuously pressed, so that the top column 303 and the arc-shaped surface 411 generate relative movement, the wedge-shaped blocks 401 are driven to rotate circumferentially while the top column 303 moves downwards until the adjacent wedge-shaped blocks 401 are matched with the wedge-shaped grooves 302 corresponding to the current top column 303, at this time, each wedge-shaped groove 302 at the bottom of the pressing column 3 is matched with each wedge-shaped block 401 on the rotating disc 4, the pressing column 3 and the rotating disc 4 are combined into a whole, and simultaneously, when the rotating disc 4 rotates, the clamping columns 5 and the screwing plates 6 are driven to rotate synchronously, so that the screwing plates 6 fasten the bottom surface of the back plate 2 and are positioned outside the opening range of the strip-shaped through hole 201, namely, the strip-shaped through hole 201 cannot pass through, and in the process, the compression amount of the tensioning spring 7 gradually reaches the maximum, the two ends of the tensioning spring respectively abut against the surfaces of the rotating disc 4 and the back shell 1, a large axial positive pressure is applied to the back shell 1 and the, the surface of the rear shell 1 is stressed by the tension spring 7, the bottom surface of the back plate 2 is stressed by the tension force of the spinning buckle plate 6, the stable fixed connection of the rear shell 1 and the back plate 2 is realized under the action of the acting force of the rear shell and the back plate, and the installation is finished.
When the disassembly between the rear shell 1 and the back plate 2 needs to be realized, the pressing column 3 only needs to be continuously pressed, and the rotating disc 4 continues to rotate for a preset angle, so that the tension on the bottom surface of the back plate 2 can be relieved by enabling the outline of the spinning plate 6 to be located in the opening range of the strip-shaped through hole 201, the spinning plate 6 can pass through the strip-shaped through hole 201, and then the pressing column 3, the rotating disc 4, the clamping column 5 and the spinning plate 6 are integrally pulled out from the mounting hole 101, and the disassembly operation can be completed.

Further, the pressing plate 801 may have a circular shape and a diameter equal to that of the mounting hole 101, so that the existence of the pressing plate 801 may shield the gap around the mounting hole 101 and prevent dust and impurities from entering the back plate 2. Meanwhile, the surface shape of the pressing plate 801 is the same as the surface shape of the rear shell 1 at the position of the mounting hole 101, for example, when the surface shape of the rear shell 1 at the position of the mounting hole 101 is a plane, the surface of the pressing plate 801 is also a plane, or when the surface shape of the rear shell 1 is an arc surface with a certain curvature, the surface of the pressing plate 801 is also an arc surface with the same curvature, so that the surface of the pressing plate 801 can be fused with the surface of the rear shell 1, the hidden design of the mounting hole 101 is realized, and the visual experience is improved.
