Described receipts nail cup 40 is detachable connection with the connected mode of the rear end cap 122 of hydraulic jack 12.When receiving nail cup 40 and being connected with the tail end of hydraulic jack 12, receive nail cup 40 and promote transmission component 16, transmission component 16 promotes the second air-breathing reversal valve 152 in air-valve assembly 15 to move forward, second back-moving spring 153 is compressed simultaneously, and between the first air-breathing reversal valve 151 and the second air-breathing reversal valve 152, gas circuit communicates；When the tail end of hydraulic jack 12 is not connected to receive nail cup 40, the first air-breathing reversal valve 151 and the second air-breathing reversal valve 152 in air-valve assembly 15 are then in sealing state, and air valve is closed.When installation receipts nail cup carries out blind rivet action, just using source of the gas, other are wasted without any source of the gas；When receipts nail cup is not installed, does not have the action of air-breathing, so can protect the safety of operator, improve the security performance of Pneumatic hand riveter.
As shown in Figure 5 to Figure 6, described guide pin pipe 13 is made up of integrated first pipeline section 131, circular cone pipeline section 132 and the second pipeline section 133, the external diameter of described first pipeline section 131 is more than the external diameter of described second pipeline section 133, in smoothing junction by circular cone pipeline section 132 between the first pipeline section 131 and the second pipeline section 133；The internal diameter of guide rod 14 leading section is slightly larger than the external diameter of the first pipeline section 131, and the internal diameter of guide rod rearward end is slightly larger than the external diameter of the second pipeline section 133；The first piston bar 121 that first pipeline section 131 passes hydraulic jack 12 extends to the rear end of described pawl set 111, and the second pipeline section 133 inserts in the leading section of guide rod 14；Described circular cone pipeline section 132, when non-blind rivet state, is positioned at the outside of guide rod 14 front end；Described circular cone pipeline section 132, when blind rivet state, is positioned at the inside of guide rod 14 front end.Described second pipeline section 133 inserts described guide rod 14, and described guide rod 14 inwall is provided with annular slot 141(and sees Fig. 1), in described draw-in groove 141, sealing ring is installed.
As it is shown in fig. 7, air-valve assembly 15 includes the first air-breathing reversal valve the 151, second air-breathing reversal valve 152 and the second back-moving spring 153.First air-breathing reversal valve 151 two ends outer wall is provided with O, is provided with two relative through holes between two O.Described through hole communicates with the gas access on hydraulic jack 12；First air-breathing reversal valve 151 is set on the second air-breathing reversal valve 152 outer wall, and the outer wall of the position that the second air-breathing reversal valve 152 is corresponding with through hole on the first air-breathing reversal valve 151 arranges O.Front end clamping second back-moving spring 153 of the second air-breathing reversal valve 152.The length of described second air-breathing reversal valve 152 is more than the length of the first air-breathing reversal valve 151, and this design is easy to receive nail cup 40 and is promoted the second air-breathing reversal valve 152 forward slip from the first air-breathing reversal valve 151, so that gas circuit is unobstructed.
During use, the afterbody at Pneumatic hand riveter is installed and is received nail cup 40, and connects source of the gas.Receive nail cup 40 and promote transmission component 16, transmission component 16 promotes the second air-breathing reversal valve 152 forward slip in air-valve assembly 15, second back-moving spring 153 is compressed simultaneously, between first air-breathing reversal valve 151 and the second air-breathing reversal valve 152, gas circuit communicates, air-flow enters hydraulic jack 12 from reset gas circuit and by the path of air-valve assembly 15, then flowed out backward by the afterbody gap of the sealing ring in guide rod 14 inwall draw-in groove 141 with guide pin pipe 13 until entering receipts nail cup 40, and make guide pin pipe 13 front end produce air-breathing and show as inhaling spike state.
Push switch pressing board 23, discharge hands the air in 20 gas circuits, switching valve 21 is made to hands, to be moved in 20 directions, gas circuit of losing heart is closed, air-flow enters bottom cylinder 30 from intake valve through airway 33, air-flow promotes piston plate 31 to move upward, the second piston rod 32 being fixed on piston plate 31 is made to promote the hydraulic oil inside oil pipe 22 to flow upwardly into hydraulic jack 12, now hydraulic oil promotes oil cylinder piston and the accessory rearward movement being connected on piston, guide pin pipe 13 rearward movement now also makes the second pipeline section 133 insert in guide rod 14, by circular cone pipeline section 132 transition, first pipeline section 131 then coordinates realization to seal with the sealing ring in guide rod 14 inboard wall groove, thus close air suction function.
Trip switch pressing board 23, switching valve 21 resets downwards, closes the air-flow entered in airway 33, opens disappointing gas circuit, and the air-flow in cylinder 30 is discharged through disappointing gas circuit by airway 33, and the first back-moving spring 123 promotes first piston bar 121 forward recovery in situ.The accessory being simultaneously connected with on cylinder piston travels forward, and now, guide pin pipe 13 travels forward and produces gap between guide rod 14；Then the air-flow entered from reset gas circuit passes through the afterbody gap of the sealing ring guide rod 14 inwall draw-in groove 141 and guide pin pipe 13 and flows out backward until entering receipts nail cup, and makes guide pin pipe 13 front end produce air-breathing and show as suction spike state.Nail is grabbed the nail of the nubbin after grip assembly blocks and is then sucked into receipts nail cup 40 through guide pin pipe 13 rearward movement.
According to the teaching of the present embodiment, those skilled in the art can realize the technical scheme in other this utility model protection domain completely.
