Detailed Description

The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to the attached

drawings

1 and 2, the blind person intelligent stick comprises a main stick body 1, a language prompter and a communication chip, wherein the language prompter and the communication chip are installed in the main stick body 1, the main stick body 1 is made of a round hollow carbon fiber tube, an expansion joint 2 is movably sleeved on the upper portion of the main stick body 1, a handle 3 is fixed at the top of the expansion joint 2, the lower portion of the expansion joint 2 is movably sleeved in the main stick body 1, an adjusting bolt is arranged on one side of the upper portion of the main stick body 1, the expansion joint 2 after being sleeved is locked through the adjusting bolt, the handle 3 is fixed at the top of the expansion joint 2, and a T-shaped shape is formed between the fixed handle 3 and the expansion. The main support rod 4 is formed by downwards extending the center of the bottom of the main stick body 1, the main support wheel 5 is installed at the bottom of the main support rod 4, one side of the bottom of the main stick body 1 is obliquely extended to form a guide support rod 6, the guide support rod 6 is made of a round hollow carbon fiber tube, the number of the guide support rods 6 is 2 or more than 2, a 30-45-degree included angle is formed between the guide support rod 6 and the main support rod 4, the bottom of the guide support rod 6 is contracted to form a bottom limit ring, inductors 10 are installed in the inner cavities of the guide support rods 6, the inductors 10 are at least two and are respectively located above and below the inner limit rings, the inductors 10 are connected with a language prompter, the language prompter and a communication chip are installed at the lower part of the main stick body 1, and a call button. The movable sleeve is equipped with and visits way pole 7 in the

guide support pole
