In the utility model, the driving structure drives the two semi-locking members to move to both sides, and the arc-shaped engaging block inside the semi-locking member moves out from the spacing groove between the two adjacent arc-shaped fixing strips outside the telescopic inner rod. After the arc-shaped engaging block is lost, the telescopic inner rod can be pulled outward along the inner telescopic cavity of the lower sleeve, and the pulling-out process is smooth. Moreover, because the outer diameter of the arc-shaped fixing strip is the same as the diameter of the inner telescopic cavity, the pulling-out direction is single, and it will not shake or swing left and right.

The locking mechanism limits the position of the telescopic inner rod. The locking mechanism limits the position of the telescopic inner rod. At this time, the height of the lower sleeve and the telescopic inner rod is fixed, which assists in surveying and mapping. Due to the presence of the locking mechanism, the height of the lower sleeve and the telescopic inner rod can be adjusted according to actual operation, and there are different height states, which solves the problem that the current telescopic folding rod often needs to be fully extended to lock the telescopic position, so that its use is mainly in a shortened state and a fully extended state, which is relatively extreme and has limitations for use in some places where a surveying rod does not need to be too long.
[0015] 2. In the utility model, the reverse rotation of the rotating hand wheel drives the two-way threaded rod to rotate, and the sliding block threadedly connected to the two-way threaded rod moves to both sides, driving the two semi-locking parts to move to both sides; the rotation of the rotating hand wheel drives the two-way threaded rod to rotate, and the sliding block threadedly connected to the two-way threaded rod moves toward the middle, and the two semi-locking parts move toward the middle. The drive structure is provided at the upper end of the lower sleeve to help move the two semi-locking parts, and assist in locking the lower sleeve and the telescopic inner rod after the height is adjusted.

The telescopic inner rod 5 is continuously pulled outward until it meets the position measurement process. In the process of taking the height standard as a reference object, the telescopic inner rod 5 maintains a stable outward moving state; a locking mechanism 13 is arranged on the upper end of the lower sleeve 1 along the outside of the telescopic inner rod 5, and the locking mechanism 13 is composed of two semi-locking members 14, and the semi-locking member 14 includes a connecting semi-ring 15, and an arc-shaped engaging block 18 is fixed equidistantly from top to bottom inside the connecting semi-ring 15.
