In the middle of the slide groove 21, one end of the two blocks 26 is fixedly connected with a card plate 27, one end of the card plate 27 is slidably engaged with the middle of the elastic buckle 24, a sliding groove 28 is provided in the middle of one end of the block 26, one end of the sliding groove 28 is fixedly connected with a spring 31, one end of the spring 31 is fixedly connected with a protrusion 30, the protrusion 30 is engaged with the groove 22, a moving groove 29 is provided below one end of the block 26, the moving groove 29 is connected with the sliding groove 28, the lower end of the protrusion 30 is fixedly connected with a shift block 32, and the shift block 32 is slidably engaged with the middle of the moving groove 29.

[0025] The following is a detailed description of the specific settings and functions of this embodiment. When installing the electric telescopic leg 2, the dial block 32 is pushed to slide along the moving groove 29, thereby driving the protrusion 30 to squeeze the spring 31 back into the sliding groove 28, and then the block 26 above the electric telescopic leg 2 is slid along the inside of the sliding groove 21 until the card plate 27 is inserted into the middle of the elastic buckle 24. The two ends of the elastic buckle 24 are pulleys 25. When the card plate 27 is inserted into the middle of the elastic buckle 24, the two pulleys 25 will roll inward for easy installation. At this time, the protrusion 30 squeezes the spring 31 and retracts it into the sliding groove 28. The block 30 will also move to the groove 22, and the limit spring 31 without the slide groove 21 will rebound and make the protrusion 30 stuck in the groove 22, so as to limit the electric telescopic leg 2. When disassembling, the block 32 is also moved to drive the protrusion 30 to squeeze the spring 31 and retract it into the sliding groove 28, and then the electric telescopic leg 2 is pulled outward. At this time, the pulley 25 will roll outward under the action of the clamping plate 27 to assist in disassembly. The electric telescopic leg 2 can be removed by continuously pulling, and the efficiency of installation and disassembly is improved by the quick-release structure.

[0026] Embodiment 2, as Figure 1 and Figure 2 As shown, a drawer 12 is slidably connected to one end of the table top 1, a partition 14 is fixedly installed in the middle of the drawer 12, a built-in handle 13 is provided in the middle of one side of the drawer 12, a double-layer frame 15 is fixedly connected to the top of the other end of the table top 1, a wire groove 18 is provided in the middle of the other end of the table top 1, a baffle 16 is rotatably connected to the upper end of the wire groove 18, and a built-in handle 2 17 is provided in the middle of the upper end of the baffle 16.

[0027] The effect achieved by the entire embodiment is that when installing the electro - telescopic leg 2, the dial block 32 is toggled to slide along the moving groove 29, thereby driving the convex block 30 to squeeze the spring 31 to retract into the sliding groove 28. Then, the latch 26 above the electro - telescopic leg 2 is slid along the inside of the sliding groove 21 of the tabletop 1 until the clamping plate 27 is inserted into the middle of the elastic buckle 24. The two ends of the elastic buckle 24 are pulleys 25. When the clamping plate 27 is inserted into the middle of the elastic buckle 24, the two pulleys 25 will roll inward, facilitating installation. At this time, the convex block 30 will also move to the groove 22. Without the limit of the sliding groove 21, the spring 31 will rebound and make the convex block 30 snap into the groove 22, which can limit the electro - telescopic leg 2. After installation, the user can adjust the height of the two electro - telescopic legs 2 according to needs, and then adjust the height of the tabletop 1. The provided drawer 12 can hold some daily necessities, and a partition 14 is also provided in the middle to divide the space of the drawer 12. By opening a wire trough 18 on the other side of the tabletop 1, the desk can not only be used for study, but also be wired to place some TVs or other electronic devices, thereby improving the applicability of the desk and having a larger user group. When disassembling, the dial block 32 is also toggled to drive the convex block 30 to squeeze the spring 31 and retract into the sliding groove 28, and then the electro - telescopic leg 2 is pulled outwards. At this time, the pulleys 25 will roll outwards under the action of the clamping plate 27 to assist in disassembly, and the electro - telescopic leg 2 can be removed by continuously pulling. The quick - release structure is used to improve the installation and disassembly efficiency.

[0028] The usage method and working principle of this device: When installing the electro - telescopic leg 2, the dial block 32 is toggled to slide along the moving groove 29, thereby driving the convex block 30 to squeeze the spring 31 to retract into the sliding groove 28. Then, the latch 26 above the electro - telescopic leg 2 is slid along the inside of the sliding groove 21 of the tabletop 1 until the clamping plate 27 is inserted into the middle of the elastic buckle 24. The two ends of the elastic buckle 24 are pulleys 25. When the clamping plate 27 is inserted into the middle of the elastic buckle 24, the two pulleys 25 will roll inward, facilitating installation. At this time, the convex block 30 will also move to the groove 22. Without the limit of the sliding groove 21, the spring 31 will rebound and make the convex block 30 snap into the groove 22, which can limit the electro - telescopic leg 2. After installation, the user can adjust the height of the two electro - telescopic legs 2 according to needs, and then adjust the height of the tabletop 1. The provided drawer 12 can hold some daily necessities, and a partition 14 is also provided in the middle to divide the space of the drawer 12. The wire trough 18 opened on the other side of the tabletop 1 enables the desk to not only be used for study, but also be wired to place some TVs or other electronic devices, thereby improving the applicability of the desk. When disassembling, the dial block 32 is also toggled to drive the convex block 30 to squeeze the spring 31 and retract into the sliding groove 28, and then the electro - telescopic leg 2 is pulled outwards. At this time, the pulleys 25 will roll outwards under the action of the clamping plate 27 to assist in disassembly, and the electro - telescopic leg 2 can be removed by continuously pulling.
