[0024] The specific implementation process of the utility model is as follows: when in use, the device is moved to the specified position through the moving wheel 2, and the screw sleeve 43 is manually rotated. The screw sleeve 43 rotates and the stud 3 performs a threaded movement, thereby causing the screw sleeve 43 to move downward, and the screw sleeve 43 drives the slip ring 44 to move downward. The movement of the slip ring 44 causes the connecting rod 46 to deflect, and the deflection of the connecting rod 46 causes the slide seat 41 to extend out of the base 1, so that the distance between the end of the slide seat 41 and the base 1 becomes larger, and then the insertion rod 48 is rotated 90 degrees so that the position of the stopper 49 and the special-shaped hole 47 corresponds, and the pressure plate 410 is stepped on downward, so that the insertion rod 48 enters the ground, and at the same time, the pressure rod 411 is deflected and contacts the slide seat 41, and the screw sleeve 43 and the stud 3 perform a threaded movement, thereby causing the slip ring 44 to drive the connecting rod 46 to deflect, thereby causing the slide seat 41 to extend out of the base 1, and the device is fixed by inserting the limit rod 76 into the ground, and the device is placed on the ground. The support is more stable to prevent the placement stability of the device from being affected by excessive external wind force. When the monitor 6 is in use, the pull plate 75 is manually pulled up, and the pull plate 75 drives the limiting rod 76 to move up and separate from the outer shell 71, and the limiting rod 76 drives the retaining ring 77 to move. The movement of the retaining ring 77 compresses the spring 78, and then the inner shell 72 is rotated so that the opening positions on the inner shell 72 and the outer shell 71 correspond. Then the pull plate 75 is released, and the spring 78 is reset to cause the retaining ring 77 to drive the limiting rod 76 to move downward, so that the limiting rod 76 is inserted into the insertion hole at the corresponding position of the outer shell 71, limiting the inner shell 72. By rotating the inner shell 72, the inner shell 72 is rotated relative to the outer shell 71, and then the inner shell 72 and the outer shell 71 cooperate, so that the monitor 6 can be protected when the monitor 6 is idle. At the same time, the spring 78 acts on the retaining ring 77, so that the limiting rod 76 can be inserted into the outer shell 71, which is convenient for limiting after the inner shell 72 is rotated.
