The feature of the present invention is to employ a guard plate sleeved on a shaft tube of the basic stand standing with a spring and controlled by two opposite beveled guide slots on the upper portion of the shaft tube of the basic stand and a couple of opposite projections in the inner wall of the tube portion of the guard plate fitting in the beveled guide slots.
