By providing the damper, the stability of the lifting and lowering of the connecting arm 2 is ensured.

[0040] In order to increase the stability of the connecting arm 2, the connecting arm 2 also includes a fixing member 25 that fixes the first connecting member 271 and the second connecting member 272 together. The fixing member 25 is "U"-shaped, with one side of the fixing member 25 fixedly connected to the first connecting member 271, and the other side of the fixing member 271 fixedly connected to the second connecting member 272.

When the first shell 21 and the second shell 22 are spliced ​​together, the first make way groove 211 and the second make way groove 221 are spliced ​​together to form a make way hole. The shielding member is provided between the make way hole and the receiving space 2621 (see Fig.12 The clearance hole can provide a clearance space when the connecting arm 2 rotates, but because of the existence of the clearance hole, the second end 262 located at the clearance hole can be seen. Fig.13 , Fig.14 ), shielding the receiving space 2621 of the second end 262, thereby increasing the aesthetics of the overall appearance and preventing foreign objects from entering the receiving space 2621 and affecting the performance of the components in the receiving space 2621.

[0043] In this embodiment, the first support member 26 is a gas spring, which can fix the connecting arm 2 at any height.

[0044] See also Fig.10 and Fig.11 As shown, when the connecting arm 2 is in a horizontal position, the protrusion 2711 abuts against one side of the recess 2811, and when the connecting arm 2 is in an inclined position, the protrusion 2711 abuts against the other side of the recess 2811. This arrangement allows the connecting arm 2 to rotate within a set angle range.

[0045] See also Figures 6 to 9 As shown, in the lifting direction of the connecting arm 2, the first end 261 and / or the second end 262 can adjust the height. By changing the height of the first end 261 and / or the second end 262, the tilt direction of the first support member 26 is changed, thereby changing the force of the first support member 26. In this embodiment, the first support member 26 is a gas spring without a switch. By adjusting the height of the second end 262, the force of the first support member 26 can be changed, so that the first display 1 can stay at any position. If the force of the first support member 26 is large, the first display 1 will rise to the highest position, and if the force of the first support member 26 is small, the first display 1 will fall to the lowest position. By changing the force of the first support member 26, the first display 1 can stay at any height position. The first support member 26 is a gas spring without a switch. By adjusting the height of the second end 262, the force of the first support member 26 is changed, so that the first display 1 can obtain a balanced force, so that the first display 1 can stay at any position.

[0046] Specifically, the second mounting seat 24 includes an installation space 243 for accommodating the second end 262, a first groove 241 located at one side of the installation space 243, a second groove 242 located at the other side of the installation space 243, and a fixed wall 244 disposed below the installation space 243. The connecting arm 2 also includes a first adjusting member 292 connected to the second end 262 and disposed in the first groove 241, and a second adjusting member 293 connected to the second end 262 and disposed in the second groove 242.
