[0002] The patient's lower limbs need a period of nursing recovery after treatment. If one of the lower limbs is under treatment, crutches will be used to assist the patient in walking during the nursing stage. Currently, crutches all have a single pole. For walking on a flat road, crutches can normally assist the patient in walking. However, when going up and down stairs, it takes a long time for the patient to use crutches, and the patient is more tired. Because either the crutch or the limb moves first, the patient's center of gravity is unstable and it is easy for the patient to fall backward.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a technical solution:

[0028] See also Figure 1-8 , a rehabilitation auxiliary walking stick, the stick rod of which is composed of an inner stick rod 2 and an outer stick rod 3, the inner stick rod 2 and the outer stick rod 3 are slidably connected, and the outer part of the stick rod has an auxiliary structure for going up and down stairs. When the patient goes upstairs, the handle 1 of the crutch is clamped under the patient's arm, and the palm part turns on the switch of the winding device 10. At this time, the motor 104 drives the shaft rod 101 and the take-up wheel 102 to rotate to release the line. At this time, the pull rope 1 8 and the pull rope 2 14 both start to unwind, and the long bracket 6 and the short bracket 13 are not subject to tension. The long bracket 6 rotates counterclockwise and the short bracket 13 rotates clockwise. At the same time, the cylinder 16 will drive the outer stick rod 3 to descend along the inner stick rod 2 until the two bracket limiting blocks 7 are simultaneously fitted into the two L-shaped notches 12 of the ring 5. At this time The two bracket limiting blocks 7 will restrict the long bracket 6 and the short bracket 13, so that the long bracket 6 and the short bracket 13 cannot rotate counterclockwise or clockwise. When the patient places the walking stick on a certain step, the short bracket 13 is on the upper step, and the long bracket 6 is on the lower step. When the entire crutch supports the patient, even if the patient's center of gravity is unstable, the long bracket 6 and the short bracket 13 can provide additional support to prevent the patient from leaning forward or backward. When the patient continues to go upstairs, when the walking stick needs to step onto the upper step, the motor 104 and the cylinder 16 work in reverse. At this time, the length of the walking stick is shortened, and the stair-going and -going auxiliary structure is stored, which makes it convenient for the walking stick to enter the upper step, and then the auxiliary structure is unfolded again.

[0029] Among them, the purpose of adding a cable tie ring 1 9 and a cable tie ring 2 on the outside of the pole is to fit the pull rope 1 8 and the pull rope 2 to the outer wall of the pole to prevent the scattered pull rope 1 8 and the pull rope 2 from becoming a hindrance, and adding two rows of cable tie rings 3 15, and the pull rope 2 14 passes through several cable tie rings 3 15 and several cable tie rings 2 in sequence, the purpose of which is to increase the thread of the pull rope 2 to be consistent with the thread of the pull rope 1 8. Since the short bracket 13 and the long bracket 6 rotate at different angles, and the angle between them and the pole bracket is also different, when the threads of the two pull ropes are consistent, synchronous winding can be achieved.

[0030] An annular groove is upwardly arranged at the bottom of the outer stick 3, and a slip ring 17 is slidably connected inside the annular groove. A rubber bottom 4 is movably arranged at the bottom of the outer stick 3, and the slip ring 17 is fixed to the rubber bottom 4. Its purpose is to make the up-and-down stair auxiliary structure adapt to steps of different heights. The end of the short bracket 13 is pointed toward the side of the stick, and the end of the long bracket 6 is pointed away from the side of the stick, so that the ends of the short bracket 13 and the long bracket 6 are firmly in contact with the anti-slip strip on the step to prevent the short bracket 13 and the long bracket 6 from slipping on the step.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
