[0014] The advantages and positive effects of the utility model are: when it is necessary to adjust the height, first step on the unlocking switch (spring-reset foot valve), and then rotate the designed table top to adjust the height of the designed table top under the cooperation of the external thread and the screw hole adjustment seat. There are several advantages here. The first is that there is no need to bend down when adjusting, which is more labor-saving and convenient, and because the edge of the designed table top is far away from the axis of the adjustment column, it is more labor-saving when rotating. Even if heavier objects are placed on the designed table top, the designed table top can be raised effortlessly. When reaching the specified position, release the spring-reset foot valve to lock it. When it is necessary to adjust the angle, pull out the plug-in locker, and then hold the designed table top with your hand to adjust it back and forth. After reaching the specified angle, release the plug-in locker so that its front end is inserted into the adjustment locking socket to lock it. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In specific implementation, when it is necessary to adjust the height, first step on the unlocking switch (spring-reset foot valve 23), and then rotate the designed table top 10 to adjust the height of the designed table top 10 under the cooperation of the external thread 16 and the screw hole adjustment seat 17. There are several advantages here. The first is that there is no need to bend down when adjusting, which is more labor-saving and convenient. Moreover, since the edge of the designed table top 10 is away from the axis of the adjustment column 13, it is more labor-saving when rotating. Even if heavier objects are placed on the surface of the designed table top 10, the designed table top 10 can be lifted effortlessly. When reaching the specified position, release the spring-reset foot valve 23 to lock it. When it is necessary to adjust the angle, pull out the plug-in lock 14, and then hold the designed table top 10 by hand to adjust it back and forth. After reaching the specified angle, release the plug-in lock 14 so that its front end is inserted into the adjustment locking hole 12 for locking.
