The piston rod in the cylinder can move up and down under the action of pressure, and cooperates with the adjustment handle to realize the lifting function of the seat. The first lifting pneumatic rod and the second lifting pneumatic rod are technical means well known and mastered by those skilled in the art and can be obtained commercially. They will not be described in detail here; the locking member 9 includes a locking sleeve 10 elastically connected to the first lifting pneumatic rod 3, and an annular plate is welded on the first lifting pneumatic rod. The bottom of the annular plate is connected to the locking sleeve via a spring. The bottom surface of the locking sleeve 10 is processed with a friction locking surface 11 opposite to the top of the rotating seat 7, and the friction locking surface 11 is covered with a rubber layer. The upper part of the locking sleeve 10 is integrally formed with an annular stepping plate 12. When the nurse sits on the chair, she steps on the stepping plate with her feet. At this time, the locking sleeve moves downward, and the friction locking surface squeezes the rotating seat to form resistance. The rotating seat and the telescopic cross bar cannot move to achieve fixed direction. After the nurse's foot is released, the locking sleeve moves up again with the elasticity to release the lock; the upper side surface of the rotating seat 7 is an inclined surface; the friction locking surface 11 encloses a truncated cone shape that fits the upper part of the rotating seat 7, increasing the contact surface to increase friction; the first movable seat 1 includes a first base 13, and the side of the first base 13 is welded with three first support inclined plates Rod 14, the end of the first supporting diagonal rod 14 is equipped with a first moving wheel 15; the second moving seat 2 includes a second base 16, and two second supporting diagonal rods 17 are welded on the side of the second base 16, and the end of the second supporting diagonal rod 17 is equipped with a second moving wheel 18, and the first moving wheel and the second moving wheel are both universal wheels; the second supporting diagonal rod 17 is located on both sides of the extension line of the telescopic cross bar 8.
