Therefore, the elderly walking through the walking pole and the sick or disabled users climbing the mountain can be usefully used as a walking and mountain aid.

Conventional walking poles configured as described above are used to fit the user's body through free length adjustment, but there is a problem such that difficulty in adjusting the proper length according to the body shape is difficult because the length adjustment is not fine.

In other words, after assembling a plurality of tubes having different diameters sequentially, the small diameters are pulled out from the larger diameters and expanded to adjust the length, and thus, the length adjustment according to the user's body cannot be made fine. There was this.

In order to solve this problem, a product having a fine length adjustment by forming a screw thread on the outer circumferential surface of a small diameter tube and slidably joining the large diameter tube has been proposed and used. There were also problems such as frequent wear and damage of nasan acid due to unreasonable operation.

In addition, when the use of the pole is frequently disabled due to such wear or damage, the reliability of the product is lowered, resulting in difficulties in generating profits of the producers.

Therefore, the present invention aims to solve the problems as described above so that the user can recognize the fixed limit according to the length adjustment of the pole, thereby preventing the occurrence of wear or damage.

It is an object of the present invention to provide a walking pole that enables the user to recognize a fixed limit according to the length adjustment to prevent the occurrence of wear or damage due to excessive operation.

Another object of the present invention is to provide a walking pole that can contribute to the profit generation of the producer by increasing the competitiveness through improving the reliability of the product.
