Mechanism for adjusting a telescoping member

An improved mechanism for adjusting a telescoping member used on a hiking or trekking pole, the improved mechanism comprising:

• a first pole member comprising an outer diameter and an inner diameter;
• a collet comprising a top portion securely coupled to the inner diameter of the first pole member, the collet further arranged on a lower portion of the first pole member and the collet comprising a bottom portion extending beyond a lower end of the first pole member, the collet further comprising at least one external thread;
• a second pole member having a second pole inner diameter larger than the first pole outer diameter and the second pole inner diameter further comprising an internal groove adapted to selectively engage the collet external thread and whereby the second pole member is selectively adapted to slide over the first pole member;
• and
• a handle member arranged on top of the first pole member, the handle member comprising an actuator button coupled to an internal spring coupled to a rod extending through the first pole member, the rod terminating in a plunger end, the plunger end extending through the collet and adapted to selectively engage and release the collet.
