A stand for a drying gun supporting frame includes a body and a socket at 90 degrees to the body. A spherical valve is disposed in the body, and a connecting unit is provided at the top of the body. The socket has a threaded hole at one side to receive a manual screw therein so as to secure a balancing pipe thereat. The spherical valve disposed in the body comprises a ball, washers, a cap and a linking rod. The altitude of the spherical valve is lower than the center of the balancing pipe, which lowers the outlet of the drying gun and provides a steady operation of the drying gun.
