At the same time, the vertical height of the two arms of the scissors bracket 304 increases, so that the rear top of the scissors bracket 304 moves forward, and the top sliding rod 303 is driven to move forward on the top sliding rail 302 through the rear top of the scissors bracket 304, thereby completing the lifting process.

[0026] See also Figure 1-Figure 3The leg placement component 5 includes a rotating seat 501 fixedly connected to the two ends of the front side of the sofa body 1, the inner walls of the two rotating seats 501 are rotatably connected with a rotating shaft 502, a limited seat 503 is fixedly connected between the two rotating shafts 502, the bottom end of the limited seat 503 is fixedly connected with a leg support seat 509, and the rear ends of the leg support seat 509 are provided with placement grooves 504. The leg placement component 5 also includes a hydraulic rod 505 connected to the inner walls of the two placement grooves 504, the bottom ends of the two hydraulic rods 505 are fixedly connected with a magnetic base 507, the output ends of the two magnetic bases 507 are fixedly connected with a threaded sleeve 506, and the front end outer walls of the two placement grooves 504 are fixedly connected with a threaded rod 508. One side of the inner side of the placement groove 504 is a magnetic inner wall. When the hydraulic rod 505 is placed in the placement groove 504, the bottom surface of the magnetic base 507 is just adsorbed with the magnetic inner wall of the placement groove 504, thereby avoiding the possibility of the hydraulic rod 505 slipping during the engagement process.

[0027] Working principle and use process: when the user needs to adjust the height of the sofa, the motor 401 is started, and the output end of the motor 401 drives the screw rod 402 to rotate, and the screw rod 402 drives the threaded ring 403 to transmit, and the threaded ring 403 drives the bottom end slide bar 305 to slide forward on the bottom end slide rail 306, and the bottom end of the rear side of the scissors bracket 304 is driven to move forward through the bottom end slide bar 305, so that the scissors bracket 304 rotates with its center as the center of the circle, so that the vertical height of the scissors bracket 304 is increased, thereby driving the rear side top of the scissors bracket 304 to move forward, and the top end slide bar 303 is driven to slide forward on the top end slide rail 302 through the rear side top of the scissors bracket 304, so that the limiting top frame 301 is driven to move upward through the scissors bracket 304, so To adjust the vertical height of the sofa body 1, when the user needs to use the leg placement assembly 5, the leg support seat 509 is rotated to a horizontal position, and the limit seat 503 is driven to rotate to a horizontal position through the leg support seat 509. At this time, the hydraulic rod 505 inside the placement slot 504 is taken out, and the threaded sleeve 506 at the output end of the hydraulic rod 505 is threadedly fixed to the threaded rod 508, and the hydraulic rod 505 is started, and the output end of the hydraulic rod 505 moves upward. At this time, the bottom end of the hydraulic rod 505 is in a suspended state. When the leg support seat 509 remains stationary, the bottom end of the hydraulic rod 505 is driven to move downward through the principle of reverse force, and the magnetic base 507 is driven to move downward through the bottom end of the hydraulic rod 505, so that the magnetic base 507 moves to the ground.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
