Compared with the existing walking aids of the same kind, the present invention has remarkable beneficial effects as follows:

(1) Since the left and right frames of the supporting frame in the walking assist device are quadrilateral frames, the two quadrilateral frames are connected by the front crossbeam A and the front crossbeam B, and the human body is located between the two quadrilateral frames. When this walking assist device assists in walking, the walking assist device is relatively stable and will not tip over.

(2) The human body is located between the two quadrilateral frames, that is, the human body is located in the middle of the walking aid device, and the overall occupied space is small, which will not cause inconvenience to the surrounding pedestrians.

(3) The front crossbeam A and the front crossbeam B are located at the upper half of the support frame, which will not affect the forward movement of the legs when walking.

(4) Since the movement of the walking assistance device is based on the rolling of the front and rear rollers, the walking assistance device can move forward with a small forward thrust when walking, and there is no need to lift the walking assistance device. The device, therefore, assists walking with this walking aid, effortlessly.

(5) The rear roller device is matched with the braking system. When walking, hold the left and right brake handles with both hands, and the brake handles will rotate around the support. At this time, the brakes in the brake system will be tightened. The brake wire, the brake wire will lift the guide rod and the brake rod, the guide rod in the brake system will move upward in the spring, and the end face of the brake rod will press the spring to move upward, at this time, the spring is compressed, and the brake The moving rod will be withdrawn from the brake groove of the brake roller, and a slight force will be applied to the walking assist device, and the walking assist device will move forward. When stopping walking, release the brake handle with both hands. At this time, the guide rod in the brake system will move downward, and the end surface of the brake rod will move downward under the action of spring tension, and the brake rod will be inserted into the brake roller. In the brake groove of the brake roller, the brake roller is stopped to rotate, and the brake roller drives the rear roller and the roller shaft in the rear roller device to stop rotating. At this moment, the two rear rollers stop rolling, and the walking assist device also stops moving forward. The human body stops walking, the hand releases the brake handle, and rests on the armpit support in the walking assist device, which is labor-saving and safe.

(6) When the brake handle is released, the rear rollers will not roll, and the walking assistance device will not move forward; when the brake handle is held, push forward slightly, the rear rollers will roll, and the walking assistance device will move forward. This point is just opposite to the braking process of the conventional braking device.

(7) When walking, put the left and right arms on the left and right armpit supports. The underarm supports have built-in shock absorbers. The shock absorbers are designed according to the principle of dynamics. When there is impact vibration, the vibration will be reduced. Absorbed by the vibrator, the two arms will not be subjected to strong vibrations, and will not feel numb.

(8) The shape of the underarm support is designed according to the shape of the armpit of the human body. The shape of the underarm support is arc-shaped, which conforms to the principle of ergonomics. You will feel very comfortable when you put your arms on the left and right underarm supports.

(9) This invention does not need a power supply, and it can be moved forward manually directly.

(10) The present invention has a simple structure and is easy to use. Using the walking assistance device to assist walking does not take up a large space, is stable, labor-saving, does not vibrate the arms, and is safe and reliable.
