In this embodiment, the inside of the crutch grip 1 is further provided with a microprocessor, a positioning module and a communication module, both the positioning module and the communication module are electrically connected with the microprocessor, and the power supply device 104 with a USB charging connector supplies power to the microprocessor; the positioning module can position the specific position of the old man at any time, and the positioning module can be connected with the mobile phone terminal through the communication module, so that the family can conveniently master the position of the old man in real time and the old man is prevented from being lost.

The working principle and the process of the invention are as follows:

the single-foot support is used:

when the sleeve 41 is rotated in the forward direction, the sleeve 41 rises, the bearing sleeve box 42 is further driven to rise, the connecting rod 43 is further used for driving the sliding block 44 and the movable shaft 49 to slide upwards in the sliding groove 46 on the supporting leg 45, the sliding block 44 is in running fit with the movable shaft 49, the supporting leg 45 is lifted upwards and tightened in the rising process of the connecting rod 43, when the sleeve 41 rises to the maximum height, the supporting leg 45 is lifted upwards and tightened to the maximum position, and the dome rubber head 6 leaks out at the moment and can be in contact with the ground, so that the single-foot support is realized;

when stopper 7 does not lock at four-hole spout section 31, when walking, the downward pressure that walking stick handle 1 produced can be transmitted on four-tailed piece 52 through adjusting pole 2, and then make the axis body 51 of being connected with four-tailed piece 52 downstream, axis body 51 lower extreme passes through countersunk head 6 screw connection with calotte rubber head 6 again, and then make calotte rubber head 6 downstream of being connected with it, just can keep calotte rubber head 6 and ground contact all the time, at this moment, the whole no deformation of walking stick produces, do not have too big difference with ordinary walking stick, but when walking, spring 53 on the axis body 51 can play the effect of absorbing vibrations and buffering to the walking stick is whole.

The four feet support and use:

when the sleeve 41 is rotated reversely, the sleeve 41 descends to drive the bearing sleeve box 42 to descend, and then the connecting rod 43 drives the sliding block 44 and the movable shaft 49 to slide downwards in the sliding groove 46 on the supporting leg 45, and the sliding block 44 is in running fit with the movable shaft 49, in the downward movement process of the connecting rod 43, the supporting leg 45 is pushed downwards, when the bearing sleeve box 42 descends and contacts with the disc 34, the supporting leg 45 descends to the maximum position, the four supporting legs 45 are opened, at the moment, the anti-skidding foot pad 47 at the lower end of the supporting leg 45 is in a horizontal state for stable support, and at the moment, a suspended distance is formed between dome rubber and the ground;

in the walking use process, the downward pressure generated from the crutch grip 1 is transmitted to the four-tail block 52 through the adjusting rod 2, the four-tail block 52 moves downwards, the shaft body 51 connected with the four-tail block 52 further moves downwards, and the round top rubber head 6 connected with the shaft body 6 moves downwards, so that the crutch can be in contact with the ground, a five-point support is formed at the bottom end of the crutch, and the anti-skid foot pad 47 at the bottom of the supporting leg 45 ensures that the crutch can be firmly gripped, so that the walking safety of the old is ensured;

meanwhile, the four-tail block 52 moves downwards to compress the spring 53, and the spring 53 can provide a reaction force for the first rod 21 of the adjusting rod 2, so that the force can help the old to reduce the physical consumption and play a role in arm exercise;

if the old man dislikes the elasticity that spring 53 brought, lock stopper 7 at the lower terminal surface of four-tail piece 52 through the locking screw, block that four-tail piece 52 can't move downwards, and then can not compress spring 53, can not produce reaction force.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
