[0031] Embodiment 1:

[0032] As Figure 1 , 4 , the cantilever assembly in the embodiment shown in Fig. 5 plays a role in adjusting the height of the display device. Specifically, the cantilever assembly includes two first bases 103 and two connecting rods 104. The two ends of each connecting rod 104 are respectively hinged at the first base 103. The connecting line of the hinge point of each connecting rod 104 and the first base 103 is arranged in a parallelogram shape, so that when adjusting the height of the display device, since the first base 103 connected with the base 106 is constrained by the base 106, the rotational freedom of the first base 103 in space is only maintained in the Z-axis direction, and the other first base 103 does not have rotational freedom in any direction in space, that is, after the angle of the display device is adjusted, the adjustment of the height of the cantilever does not cause the angle of the display device to change.

[0033] The locking member provided between any one end of at least one connecting rod 104 and the first base 103 is used to prevent the cantilever assembly with adjusted height from sagging.

[0034] Among them, in order to prevent foreign matter from being stuck between the two connecting rods 104, a protective cover is arranged at the cantilever assembly.

[0035] The connecting plate 102 is used to connect the display device, and the connecting plate 102 can be punched from a thin plate. The connecting plate 102 is hinged to the second base 101 through a pin, so that the pitch angle of the display device can be adjusted. In order to fix the connecting plate 102 and the second base 101 after the pitch angle of the display device is adjusted, a damper is arranged between the connecting plate 102 and the second base 101. The second base 101 and the first base 103 are connected in a plug-in manner, so that the second base 101 has a rotation freedom around the Z axis, and the yaw angle of the display device can be adjusted.

[0036] The base 106 is fixed to the desktop in use. One optional way of fixing the base 106 to the desktop is to connect the base 106 to the desktop through screws. Another optional way is that the lower part of the base 106 is provided with a clamping piece 105, and a bolt is threadedly connected to the clamping piece 105. In use, the base 106 is placed on the upper surface of the desktop edge, and the bolt at the clamping piece is rotated to make the bolt abut against the lower surface of the desktop edge, so as to connect the base 106 to the desktop.

[0037] The third base 107 arranged at the base 106 is used to support the other first base 103 of the cantilever assembly. Specifically, the third base 107 and the first base 103 are connected in a plug-in manner, so that the first base 103 has a rotation freedom around the Z axis, and the viewing distance of the display device can be adjusted.

[0038] In use, the viewing distance of the display device is adjusted by rotating the cantilever assembly. The height of the display device is adjusted by adjusting the relative positions of the connecting rod of the cantilever assembly and the first base. The yaw angle of the display device is adjusted by rotating the second base 101. The pitch angle of the display device is adjusted by adjusting the relative positions of the connecting plate 102 and the second base 101.

[0039] Embodiment 2:

[0040] On the basis of embodiment 1, as Figure 2In the shown embodiment, an alternative form of the locking member is provided, specifically, the locking member comprises a pin shaft, one end of the pin shaft is provided with a flange 111, the other end of the pin shaft is movably connected with a blocking ring 112 which is connected with the outer periphery of the pin shaft by screwing, the outer periphery of the pin shaft is provided with a protruding tooth portion 110 and a smooth portion 109, the protruding tooth portion 110 is in the form of a plurality of protruding teeth which are uniformly distributed along the axial direction of the pin shaft and extend along the axial direction, the hinge hole of the connecting rod 104 and the hinge hole of the first base 103 are both provided with internal teeth which are adapted to the protruding teeth. When the protruding tooth portion 110 at the outer periphery of the pin shaft is located at the hinge hole of the connecting rod and the hinge hole of the first base, the connecting rod 104 cannot rotate relative to the first base 103 due to the clamping effect of the protruding tooth portion 110 and the internal teeth at the hinge holes, so that the height of the cantilever assembly cannot be changed.

[0041] The two ends of the spring 108 which is sleeved at the outer periphery of the pin shaft abut against the blocking ring 112 and the first base 103 respectively, the elastic force provided by the spring 108 makes the protruding tooth portion 110 be inserted at the hinge hole of the connecting rod and the hinge hole of the first base in the natural state.

[0042] In the assembly, the connecting rod 104 is first placed at the designated position, the pin shaft is inserted into the hinge hole of the connecting rod 104 and the hinge hole of the first base 103, the spring 108 is sleeved at the outer periphery of the pin shaft from the other end, and finally the blocking ring 112 is screwed with the outer periphery of the pin shaft so that the two ends of the spring 108 abut against the blocking ring 112 and the first base 103 respectively.

[0043] In the use, the pin shaft is pressed to make the pin shaft slide, the protruding tooth portion 110 is separated from the hinge hole of the connecting rod, at this time the connecting rod 104 is no longer constrained by the protruding tooth portion 110, so that the height of the cantilever assembly can be adjusted.

[0044] In the present embodiment, in order to ensure the smooth centering of the protruding tooth portion 110 of the pin shaft and the hinge hole of the connecting rod when the protruding tooth portion 110 slides into the hinge hole of the connecting rod, the tooth root of the protruding tooth portion 110 is flush with the smooth portion 109.

[0045] When the height of the cantilever assembly is adjusted, the smooth portion 109 is located at the hinge hole of the connecting rod, the tooth top of the internal teeth at the hinge hole of the connecting rod is in contact with the smooth portion 109, when the height adjustment of the cantilever assembly is completed and the spring 108 pulls the protruding tooth portion 110 of the pin shaft into the hinge hole of the connecting rod, since the tooth root of the protruding tooth portion 110 is flush with the smooth portion 109, the smooth portion 109 guides the protruding tooth portion 110 to be smoothly centered with the hinge hole of the connecting rod.

[0046] Embodiment 3:

[0047] On the basis of the embodiments 1 or 2, when the height of the cantilever assembly is adjusted, in order to facilitate the sliding of the pin shaft, the protruding tooth portion 110 is provided with a plurality of protruding teeth which are uniformly distributed along the axial direction of the pin shaft and extend along the axial direction, the tooth root of the protruding tooth portion 110 is flush with the smooth portion 109. Figure 3The embodiment shown additionally adds a lever 113, which is hinged at the connecting rod 104, and one end of the lever 113 is clamped at the pin shaft.

[0048] In use, the connecting rod 104 provides a force point, and by pulling the lever 113, the position of the pin shaft can be adjusted to adjust the height of the cantilever, increasing the convenience in use.
