The side of the fixing sleeve 1 is respectively provided with an L-shaped hole 4, the vertical part of the L-shaped hole 4 is arranged along the circumferential direction of the fixing sleeve 1, the transverse part of the L-shaped hole 4 is connected with the vertical part and is arranged on the rear side of the transverse part, and the transverse part of the L-shaped hole 4 is arranged above the fixing sleeve 1 and is arranged in the axial direction of the fixing sleeve 1, the two ends of the seat flip rod 2 are respectively inserted into the fixing sleeves 1 on the left and right sides, the spring column 3 of the seat flip rod 2 pops out through the L-shaped hole 4 and flips and slides along the L-shaped hole 4, and the middle part of the seat flip rod 2 is fixedly connected to the seat plate 5.

[0022] Furthermore, an anti-slip positioning hole 6 communicating with the L-shaped hole 4 and facing the front side of the walker is provided at the end of the transverse portion of the L-shaped hole 4 .

[0023] Furthermore, the walker board includes a left square frame 7, a right square frame 8 and a rear connecting rod 9. The rear sides of the left square steel frame and the right square frame 8 are connected via the rear connecting rod 9, and the bottoms of the left square frame 7 and the right square frame 8 are connected to the universal wheel 10.

[0024] Furthermore, transverse connecting rods 11 are respectively provided in the middle of the left square frame 7 and the right square frame 8, and the fixed sleeves 1 are respectively connected to the rear ends of the transverse connecting rods 11. A clamping seat 12 is respectively provided on the transverse connecting rods 11 on the front side of the fixed sleeve 1. The lower end of the clamping seat 12 is fixedly connected to the transverse connecting rod 11, and the upper end of the clamping seat 12 is provided with a clamping groove 13. A detachable positioning rod 14 is clamped on the clamping groove 13, and the front lower side of the flipped seat plate 5 is supported by the positioning rod 14 to increase the stability of the seat plate 5.

[0025] Furthermore, the fixed sleeve 1 is connected to the transverse connecting rod 11 through the support column 15, and the bolt 17 passes through the through holes provided on the fixed sleeve 1 and the support column 15 and is threadedly connected to the transverse connecting rod 11. The total height of the support column 15 after being connected to the fixed sleeve 1 is consistent with the height of the clamping seat 12 after clamping the positioning rod 14, ensuring the flatness of the seat plate 5.
