The lower tube includes a shaft able to be mounted into the upper tube through an opening of the upper tube. The first and the second locking members are disposed on two opposite sides of the upper and lower bases at the position between the upper and lower bases respectively for locking the upper and the lower tubes in the connected state. In the second locking member, a pressing rod is pivotally connected to a guiding bar that is inserted through the upper base and the pressing rod abuts against the upper base.
