Because the seat plate further comprises a second nut 1721, a third screw 1722 and a second rack 1723, the second nut 1721 is mounted on the right side of the front side of the seat plate 1 in a welding mode, the third screw 1722 is screwed in the second nut 1721, the third screw 1722 is matched with the second nut 1721, the left end of the third screw 1722 is rotatably connected with the second rack 1723, the second rack 1723 is meshed with the second gear 172, when a user rotates the backup plate 5 to a required angle, the user can rotate the third screw 1722, the third screw 1722 pushes the second rack 1723 to move leftwards, the second rack 1723 is meshed with the second gear 172, and the second gear 172 is fixed and cannot rotate any more.
Because the extension device 18 is further included, the extension device 18 includes a push block 181, a third rack 182, a connecting block 183, a fourth gear 184, a fourth rotating shaft 185, a sliding sleeve 186, a fourth rack 187 and a supporting plate 188, the extension device 18 is disposed on the lower side of the seat plate 1, the push block 181 is mounted on the right side of the lower side of the push rod 179 in a welding manner, the third rack 182 is mounted on the lower side of the left side of the push block 181 in a bolt connection manner, the connecting block 183 is mounted on the upper side of the left side of the right front side bracket 2 in a welding manner, the fourth rotating shaft 185 is rotatably connected to the left side of the connecting block 183, the fourth gear 184 is connected to the front and rear sides of the fourth rotating shaft 185, the fourth gear 184 on the front side is meshed with the third rack 182, the sliding sleeve 186 is mounted on the front side of the right rear side bracket 2 in a welding manner, the sliding sleeve 186 is internally and slidably connected with the fourth rack 187, the fourth rack 187, when a user needs to comfortably perform infusion, the push rod 179 moves rightwards and simultaneously drives the push block 181 to move rightwards, the push block 181 drives the third rack 182 to move rightwards, the third rack 182 drives the front fourth gear 184 engaged with the third rack to rotate clockwise, the front fourth gear 184 drives the fourth rotating shaft 185 to rotate, the fourth rotating shaft 185 drives the rear fourth gear 184 to rotate, the rear fourth gear 184 rotates and drives the fourth rack 187 engaged with the fourth rack to move leftwards in the sliding sleeve 186, the fourth rack 187 drives the support plate 188 to move leftwards, and then the user puts feet on the support plate 188.
Because a third sponge block 1881 is also included and the third sponge block 1881 is attached to the support plate 188, the third sponge block 1881 may provide more comfort to a user when placing their foot on the support plate 188.
