The limiting piece 42 of the control module 2 is in a ring structure, a ring flange is arranged at the lower end of the ring structure, the ring flange is matched with the limiting groove 23 of the swing module 2, and is used to limit the swing of the seat. The operation handle 5 is used to control the swing or lifting of the seat.

[0044] When the operation handle 5 rotates, the control piece 41 of the control module 4 rotates relative to the swing rod 22, so that the limiting piece 42 of the control module 4 is away from the limiting groove 23 of the swing module 2, and the swing control of the seat is realized; when the operation handle 5 moves up and down, the lifting module 3 is driven to work, and the lifting control of the seat is realized.

[0045] As shown in Figure 1 and Figure 3 , the limiting block 6 is made of flexible rubber material, which is fixedly installed on the rear side of the body 1 through a screw, and is used to contact with the seat base when the seat swings, so as to limit the excessive inclination of the seat and prevent the seat from overturning backward.

[0046] As shown in Figures 3-10As shown, an opening 223 is provided on the side wall of the rocker arm 22 of the rocker module 2. The opening 223 communicates with the central hole 221 of the rocker arm 22, allowing the front end 51 of the operating handle 5 to pass through the opening 223 and enter the central hole 221 of the rocker arm 22.
