[0035] The specific usage and function of this embodiment are as follows:

[0036] When using this product, when the device is powered on, the electromagnet 1015 installed inside the movable groove 1012 generates magnetic force. Since the iron block 1014 is installed at one end of the edge block 1013, it is adsorbed by the electromagnet 1015 and then retracted into the movable groove 1012. At this time, the user can drive the bidirectional screw rod 1007 to rotate through the servo motor 1005, so that the sliders 1008 set at both ends move relatively, so as to use the connecting rod 1003 to lift the cabinet body 2001. When the device is powered off, the electromagnet 1015 loses its magnetism and is unable to adsorb the iron block 1014. The edge block 1013 is pushed out of the movable groove 1012 under the elastic force of the spring 1022, so that one end of it abuts against one end of the connecting tube 1009. When the user turns the knob 1020 by standing on a bench or ladder to a high place, the user drives the worm 1018 to rotate, and the worm 1018 engages with the worm wheel 1019 sleeved on one end of the second bevel gear 1016, thereby causing the second bevel gear 1016 to rotate, and the second bevel gear 1016 engages with the first bevel gear 1017 sleeved on one end of the connecting tube 1009, thereby causing the connecting tube 1009 to rotate. A rib groove 1011 is provided at one end of the connecting tube 1009. When the connecting tube 1009 is rotated to a suitable position, the rib block 1013 is inserted into the rib groove 1011. The knob 1020 can be turned to drive the bidirectional screw 1007 to rotate, thereby manually adjusting the height of the cabinet body 2001, thereby preventing the cabinet from affecting the use of the gas stove or counter.
