[0100] Furthermore, in some specific embodiments, Figure 1 、 Figure 6 and Figure 7 As shown, the size of the front end of the frame 102 is larger than the size of the back end of the frame 102 , and the end surface of the front end of the back cover 2 abuts against the stepped surface of the frame 102 .

[0101] Based on the above embodiment, the camera 4 is installed on the main frame 11 through the first bracket 14, the paddle 15 and the first pressure plate 16; the first bracket 14 is inserted in the third mounting slot 104, and the first bracket 14 has a shooting channel 141, and the camera 4 is inserted in the shooting channel 141; the first pressure plate 16 is provided on the side of the first bracket 14 close to the back cover 2 so as to be able to abut the camera 4; the first end of the shell 1011 along the Y direction has a first active channel 10111, the first end of the paddle 15 is inserted in the first active channel 10111, and the side of the first bracket 14 away from the back cover 2 has a second active channel 142, the second end of the paddle 15 passes through the second active channel 142 and protrudes to the outside of the shell 1011, and the paddle 15 can slide along the X direction to cover or reveal the camera 4.

[0102] like Figure 1 、 Figure 10 、 Figure 12 and Figure 13 As shown, the first bracket 14 is inserted into the third mounting groove 104. It should be noted that the fixed connection method of the first bracket 14 and the main frame 11 is not limited. For example, the first bracket 14 is bonded to the groove wall of the third mounting groove 104, or a fourth mounting through hole is opened at the bottom of the third mounting groove 104, and the first bracket 14 is opened with a fourth connecting hole. Corresponding screws are inserted into the fourth mounting through hole and the fourth connecting hole with a common diameter from left to right to fix the first bracket 14 and the main frame 11; and a through hole extending along the Z direction is opened in the middle position of the first bracket 14 as a shooting channel 141, and the camera 4 is inserted in the shooting channel 141, and the camera 4 can perform shooting operations through the left end opening of the shooting channel 141, and a pressure cover is provided on the right side of the first bracket 14 close to the back cover 2. The pressure cover can be fixedly mounted on the first bracket 14 by bonding or snapping to block the right end opening of the shooting channel 141, thereby limiting the camera 4 between the first bracket 14 and the pressure cover.

[0103] like Figure 13 As shown, a groove is provided on the left side of the first bracket 14 away from the back cover 2 as a second active channel 142, and the lower end of the paddle 15 is inserted into the second active channel 142. Correspondingly, a long strip through hole is provided on the top plate of the shell 1011 as a first active channel 10111. The upper end of the paddle 15 passes through the first active channel 10111 and extends to the outside of the shell 1011, so that the paddle 15 can be moved along the X direction by pushing the part of the structure located outside the shell 1011. When the paddle 15 moves to the first working position, the paddle 15 is opposite to the left end opening of the shooting channel 141 to block the camera 4 from performing shooting operations. When the paddle 15 moves to the second working position, the paddle 15 is located on the side of the shooting channel 141 to expose the camera 4 so that the camera 4 can perform shooting operations.

[0104] Further, in some specific embodiments, Figure 13 As shown, the first bracket 14 has two base feet on the side close to the back cover 2, and the base feet are provided with a second mounting through hole 143. The third mounting groove 104 has two mounting ribs 1018 arranged along the X direction, and the mounting ribs 1018 are provided with a second connecting hole 10181. Corresponding screws are inserted into the second mounting through holes 143 and the second connecting holes 10181 of a common diameter to fix the first bracket 14 and the main frame 11.

[0105] Furthermore, in some specific embodiments, Figure 13 As shown, the first bracket 14 is provided with at least two third connecting holes 144. For example, the first bracket 14 is provided with a third connecting hole 144 on one side of the shooting channel 141 along the X direction, and the first bracket 14 is provided with another third connecting hole 144 on the other side of the shooting channel 141 along the X direction. The first pressure plate 16 is provided with at least two third mounting through holes 161. Corresponding screws are inserted into the third mounting through holes 161 and the third connecting holes 144 with a common diameter to fix the first bracket 14 and the first pressure plate 16.

[0106] Furthermore, in some specific embodiments, Figure 13 As shown, the top of the first bracket 14 opposite to the shell 1011 has at least two elastic protrusions 145. When the paddle 15 moves to the starting position and the end position along the X direction, it can abut against the corresponding elastic protrusions 145 to limit the paddle 15 while effectively preventing the paddle 15 from being damaged by collision.

[0107] Based on the above embodiment, the two ends of the support leg 12 are rotatably mounted on the connecting plate 1012 with the X-axis as the axis through the corresponding second bracket 17 and the damping shaft 18; the second bracket 17 is detachably mounted on the connecting plate 1012, and one end of the damping shaft 18 is detachably mounted on the corresponding second bracket 17, and the other end is connected to the corresponding end of the support leg 12.

[0108] like Figure 1 As shown, the rotation center line of the damping shaft 18 extends along the X direction, and the movable end of the damping shaft 18 on the left is connected to the left end of the support leg 12, so that the left end of the support leg 12 can rotate relative to the fixed end of the damping shaft 18, and the fixed end of the damping shaft 18 is detachably arranged on the second bracket 17 on the left side, such as by snap-fitting or connecting by screws, and the second bracket 17 is detachably arranged on the back side of the connecting plate 1012, such as by snap-fitting or connecting by screws, etc.

[0109] Similarly, if Figure 1 As shown, the movable end of the damping shaft 18 on the right side is connected to the right end of the support leg 12, so that the right end of the support leg 12 can rotate relative to the fixed end of the damping shaft 18, and the fixed end of the damping shaft 18 is detachably arranged on the second bracket 17 on the right side, such as by snap-fitting or connecting by screws, and the second bracket 17 is detachably arranged on the back side of the connecting plate 1012, such as by snap-fitting or connecting by screws, etc.

[0110] With this arrangement, when the support leg 12 rotates frequently and causes the structure for fixing the fixed end of the damping shaft 18 to fail, only the second bracket 17 needs to be replaced, which helps to reduce maintenance difficulty and cost.

[0111] Based on the above embodiment, the handle 13 includes a flexible sheet 131, a second pressure plate 132, and a gripping piece 133; the first end of the flexible sheet 131 is pressed on the back side of the frame 102 through the second pressure plate 132; the second end of the flexible sheet 131 extends from between the back cover 2 and the frame 102, and is fixedly connected to the gripping piece 133; the back cover 2 is provided with a magnetic structure, and the gripping piece 133 can be magnetically attracted to the magnetic structure.

[0112] like Figure 1 and Figure 14 As shown, the lower end of the flexible sheet 131 is pressed against the back of the frame 102 by a second pressure plate 132 located on the right side thereof, and the second pressure plate 132 can be fixedly connected to the frame 102 by screws, or the second pressure plate 132 can also be fastened to the frame 102 by a male stop and a female stop, etc., and the flexible sheet 131 can adopt a nylon structure. Preferably, the flexible sheet 131 is made of leather.

[0113] It should be noted that the type of the flexible sheet 131 is not limited, for example, an I-shaped sheet or a L-shaped sheet, etc., as long as it can meet the needs of fixing the frame 102 and lifting the portable output terminal.

[0114] A gripping piece 133 is fixedly connected to the upper end of the flexible sheet 131. The gripping piece 133 adopts a ferromagnetic metal structure. Correspondingly, a magnetic structure is provided at a preset position of the back cover 2. The magnetic structure can be buried inside the back cover 2, or adhered to the inner surface or outer surface of the back cover 2. When the portable display terminal needs to be lifted, the gripping piece 133 is pulled to separate it from the magnetic structure. When the portable display terminal does not need to be lifted, the gripping piece 133 is driven to be magnetically coupled with the magnetic structure, effectively preventing the handle 13 from shaking at will, greatly improving the user experience.

[0115] It should be noted that the type of the holding member 133 is not limited. For example, the holding member 133 may adopt an open-close structure to clamp the upper end of the flexible sheet 131 inside the open-close structure.
