[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The outdoor tabletop heater, which is convenient for adjusting the tabletop height, is provided with an adjustment structure. By rotating the control knob, the driven bevel gear is driven to rotate. During this process, the driven bevel gear will drive the screw rod to rotate inside the moving block. When the screw rod rotates inside the moving block, it will drive the moving block to move up and down. Subsequently, the up and down movement of the moving block will directly affect the up and down movement of the moving shaft. Since the moving shaft is located inside the two slide grooves, the moving shaft will adjust the position of the intersection of the two slide grooves during the movement process, thereby changing the angle between the two support rods. This series of mechanical linkages ultimately realizes the adjustment of the tabletop height.

[0017] Furthermore, a limiting structure is provided. When the rotating bar rotates to a position perpendicular to the desktop, the limiting block needs to be further operated to drive the positioning slider to rotate around the end of the rotating bar. During this process, the top of the positioning slider will slide inside the guide groove under the action of the spring. When the limiting block rotates to a position perpendicular to the rotating bar, the top of the positioning slider will just enter the limiting hole inside the guide groove, thereby limiting the rotation angle of the limiting block. At this time, since the limiting block and the rotating bar remain in a perpendicular state, and the top of the rotating bar is tightly fitted with the bottom of the desktop, the limiting block can effectively fix the rotation angle of the rotating bar, so that it remains perpendicular to the desktop.

[0018] Furthermore, during the folding process, it is first necessary to ensure that the limit block is rotated to a state parallel to the rotating bar, and then the rotating bar is rotated until it is parallel to the desktop. Through the above steps, the folding operation of the device can be achieved;

[0019] Furthermore, the mounting plate and the replacement part are replaced inside the mounting hole. When the mounting plate is placed inside the mounting hole, the top of the desktop and the mounting plate will form a whole. This design enables the top of the desktop to carry more items. When the replacement part is placed inside the mounting hole, the sealing cover needs to be taken out from the inside of the sealing groove, and then the alcohol stove is ignited to achieve the heating function. In addition, through the setting of the support frame, the cooker can be placed on the top of the support frame. At this time, the replacement part can also be used as a simple stove to meet different usage requirements. BRIEF DESCRIPTION OF THE DRAWINGS
