[0006] As a further technical solution of the utility model, the lower surface of the seat cushion is fixedly connected to a base, a hydraulic cylinder is provided at the bottom end of the base, an output end of the hydraulic cylinder is fixedly connected to a top column, and the other end of the top column is fixedly connected to the base.

[0007] As a further technical solution of the utility model, a support bracket is fixedly connected to an outer wall of one side of the hydraulic cylinder, and a universal wheel is arranged on the support bracket.

[0008] As a further technical solution of the utility model, an adjuster is fixedly connected to the lower surface of the seat cushion.

[0009] As a further technical solution of the present invention, a reinforcing rib is fixedly connected to an outer wall on one side of the second partition plate, and the reinforcing rib is fixedly connected to the lumbar support.

[0010] As a further technical solution of the utility model, a positioning column is arranged on the outer wall of one side of the backrest.

[0011] As a further technical solution of the utility model, a first shell is fixedly connected to an outer wall on one side of the backrest, a second shell is fixedly connected to an outer wall on one side of the lumbar support, a connecting seat is provided on an outer wall on one side of the first shell and the second shell, and the armrest is fixedly connected to the connecting seat.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model adopts a waist and back separation structure, and separates the upper back support structure from the lower waist support structure through the groove formed between the first partition plate and the second partition plate, and inserts the supporting mesh cloth therein, and fits the user's waist and back through the ergonomic curvature of the back support part and the waist support part, thereby better protecting the user's waist and back and achieving a more comfortable riding experience.
