[0040] By setting the telescopic rod 15, when the suction head 6 is raised or lowered, the telescopic rod 15 can synchronously retract the suction head 6 into the inner side of the mounting seat 3, and then the two telescopic rods 15 cooperate to effectively limit the moving trajectory of the suction head 6 and ensure the stability of the suction head 6 when it is raised or lowered.
