Abstract: An improved structure of gyrating nozzle spray gun includes a grip including an air inlet and a trigger-controlled valve seat, a gas delivery tube connected to the valve seat, and a gyrating nozzle head including a connection nut threaded onto a front tubular mating connection screw rod of the gas delivery tube, an end cap threaded onto outer thread of the connection nut, a bearing positioned in the end cap, and a rotator mounted in the bearing and rotatable with an inner race of the bearing and defining therein a gas accumulation chamber for receiving compressed air from the valve seat via the gas delivery tube and the connection nut and an oblique jet hole eccentrically located in the front wall thereof for ejecting compressed air and causing the rotator to rotate during ejection of compressed air.

Abstract: A gyrating nozzle spray gun includes a grip including an air inlet, a valve seat, a gas-delivery tube connected to the valve seat and terminating in a mating connection portion and a trigger operable for letting external compressed air go into the air inlet and the gas-delivery tube, an attachment tube connected to the mating connection portion of the gas-delivery tube, and a gyrating pattern generator including a gas-supply tube connected to the mating connection portion and suspended in an accommodation chamber, a bearing mounted on a connecting portion, a coupling socket mounted on an outer race and a gyrating nozzle fastened to the coupling socket and rotatably disposed in an orifice and defining a gas accumulation chamber and an oblique jet hole for ejection of the intake flow of compressed air that goes through the air inlet, the gas-delivery tube and the gas-supply tube into the gas accumulation chamber.

Abstract: A hinge module applying for a first body pivotally disposed at a second body includes an axle having a baffle, a first stand, a second stand, an auxiliary stand, a washer and a pressing-element. The first stand includes a first connecting part fixed to the axle and a first fixing part fixed to the first body. The second stand includes a second connecting part pivotally connected to the axle and a second fixing part fixed to the second body. The auxiliary stand includes a third connecting part pivotally connected to the axle and a third fixing part fixed to the first or the second body. The washer is disposed between the axle and the third connecting part. The axial width of the washer is greater than that of the third connecting part. The pressing-element presses the second connecting part and the washer along an axial direction of the axle.
