The pulling member 40 is arranged on the movable seat 20, and the pulling member 40 is movable relative to the movable seat 20. The pulling member 40 has a locked state with the connecting column 32 and an unlocked state separated from the connecting column 32.

[0037] By using the installation assembly provided by the utility model, the movable seat 20 is installed on the display box. When disassembling the display box, it is only necessary to pull the pull card 40 and switch the pull card 40 to the unlocked state to separate the connecting column 32 and the movable seat 20. When installing the display box, it is only necessary to pull the pull card 40 and switch the pull card 40 to the unlocked state, place the movable seat on the fixed seat 10, and then pull the pull card 40 and switch the pull card 40 to the locked state to connect the pull card 40 and the connecting column 32, and connect the fixed seat 10 and the movable seat 20, thereby simplifying the disassembly and assembly operations of the installation assembly and the display box.

[0038] Furthermore, after the display box and the mounting assembly are installed in place, the operating member 31 can also drive the connecting column 32 to move along a preset arc direction, thereby driving the movable seat 20 to move along the preset arc direction to change the display angle of the display box.

[0039] like Figure 2 and Figure 3 As shown, the adjusting member 30 also includes a movable member 33, which is movably arranged on the fixed seat 10, the operating member 31 is drivingly connected to the movable member 33, and the connecting column 32 is movably arranged on the movable member 33 along a first direction, and the connecting column 32 has an upwardly extending snap-in position and a downwardly retracted avoidance position. When the connecting column 32 is in the snap-in position, the connecting column 32 is penetrated by the movable seat 20, and when the connecting column 32 is in the avoidance position, the connecting column 32 is disengaged from the movable seat 20 and avoids the movable seat 20. When installing the display box, the movable seat 20 is installed on the display box, and the connecting column 32 is moved to the avoidance position so that the movable seat 20 can slide onto the fixed seat 10 along the preset arc direction.
