As preferably, the bottom of the telescoping tube of described pin is footmuff fixedly, and footmuff can prevent that the telescoping tube bottom is worn, and increases the frictional force on frame pin and ground simultaneously.

In sum, the present invention compared with prior art has following advantage.

Positioner of the present utility model has utilized to have flexible torsion spring to the elastic force effect of fixture block, dop firmly is stuck on the locating hole of inner tube; After applying the pressed by external force fixture block, dop breaks away from locating hole, and the positioner of this moment can move along the inner tube easy on and off with telescoping tube, and the process of adjusting bracket pin length is very light, smooth and easy, time saving and energy saving.

Be connected with between of the present utility model pin can folding crosspiece, the anti-pressure ability of frame pin is strengthened, the stability of work stools integral body improves, bearing capacity increases, and is sturdy and durable; And crosspiece is connected between the telescoping tube, also can not affect the Telescopic of frame pin.

Crosspiece of the present utility model is foldable, by two sections hinged reaching into of rod member, can fold along with closing up of frame pin, can not affect the folding function of frame pin fully, and the work stools volume after the folding is little, and is easy to carry and store.
