[0033] A method for using a walker to effectively prevent falls includes the following specific steps:

[0034] S1. First, pass the patient's leg through the fixing ring 24. Then, by turning the knob 19, the threaded block 20 drives the fixing rod 21, the first connecting rope 23, the fixing ring 24, and the seat plate 22 to move up or down, and move the fixing ring 24 to the position of the thigh root.

[0035] S2. After the adjustment is completed, the user places both hands on the handrails 8 and walks;

[0036] S3. When the user trips and falls while walking, the fixed ring 24 and the first connecting rope 23 cause the slide 12, the connecting rod 14 and the friction block 15 to move downward, and the friction block 15 adheres to the ground, preventing the entire walker from moving and thus preventing the user from falling.

[0037] S4. When the user needs to rest, he or she sits directly on the seat plate 22. At the same time, the slide plate 12, the connecting rod 14 and the friction block 15 move downward, and the friction block 15 is in contact with the ground to prevent the walker from moving as a whole and ensure stability.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
