[0026] When the user is walking, the end of the support rod 1 and the end of the U-shaped support rod 4 are both provided with walking wheels 5, which form a quadrilateral support point with the ground. In this way, the walking wheels 5 are in contact with the ground during walking, driving the user to perform walking training operations on the ground, which makes the operation more stable. The U-shaped support rod 4 is connected to the support rod 1 by a connecting piece 3. When the user is walking, the weight of the body applies a force to the support rod 1. At this time, the buffer component 6 set between the support rod 1 and the walking wheel 5 will buffer this part of the intermittently applied force and convert it into airflow, which is then transported to the part of the hand holding the user on the handrail 2 through the blowing component 7 for suction and blowing operations, avoiding sweating and slipping at the hand holding part. In addition, when the device is walking in an outdoor environment, the buffer component 6 can buffer and limit the ground vibration, thereby improving the comfort of the device walking training and saving the physical strength of the user.

The adjusting member includes an adjusting cylinder 10 slidably connected to one end of the handrail rod 2. The end of the adjusting cylinder 10 is fixedly connected to the support rod 1. An adjusting hole 11 is opened on the surface of the adjusting cylinder 10. The end of the handrail rod 2 is located inside the adjusting cylinder 10 and a clamping member is provided. The clamping member includes a telescopic rod 12 fixed to the surface of the handrail rod 2. A protrusion 13 is fixed at the end of the telescopic rod 12. The protrusion 13 is slidably connected in the adjusting hole 11. A compression spring 14 is sleeved on the surface of the telescopic rod 12. The ends of the compression spring 14 are respectively fixedly connected to the protrusion 13 and the handrail rod 2. The connecting member 3 is made of spring plate material. The four walking wheels 5 are on the same horizontal mounting surface.

[0028] In the utility model, when in use, regardless of the vibration caused by the walking road surface or the force applied by the user's weight, the elastic rebound of the extrusion spring 64 can buffer the force applied thereto, so that the user can support the device for walking training more easily and with less effort. When the force is applied, the piston 63 slides inside the connecting cylinder 62. At this time, the air inside the connecting cylinder 62 is squeezed and can be transported to the air pipe 71 through the air outlet 65, and then sprayed out through the nozzle 73. Since the spray direction of the nozzle 73 points to the handle 8, the hand of the user holding the handle 8 is sucked and blown, and the blown air flow dries the hand, reduces the occurrence of sweating and slipping of the hand due to the use of the device, and improves the comfort and safety of the device. According to the height of the user, the placement height of the handrail 2 can be adjusted and controlled by the adjusting member, so that the device is suitable for people of different heights.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
