The specific embodiment:

Referring to Fig. 1, novel Nut riveter is mainly by cylinder end piece 1, cylinder piston 2, air supply pipe 3, rifle body 4, oil cylinder piston 5, cylinder cover 6, reversal valve 7, pressure channel 8, starting handle 9, switch 10, oil pressure pipeline 11, rifle head capsule 12, rifle head 13, contiguous block 14, spring clamp nut 15, spring 16, pivot 17 in the rotation, planet pin 18, piston rod 19, motor seat 20, push rod 21, bearing 22, spheroid 23, bonnet 24, end cap 25, air leakage hole 26, inlet channel B27, distributor 28, just changeing gas passage 29, inlet channel A30, counter-rotating gas passage 31, baric area 32, blower motor 33, oil pressure district 34, air inlet 35, baric area 36, valve piston 37, air leakage hole 38, silencer 39 and inlet channel 40 are formed.Cylinder piston 2 is sleeved on rifle body 4 bottoms, oil cylinder piston 5 one ends are sleeved in the rifle body 4 by cylinder cover 6, the other end is fixed in the cylinder piston 2, rifle body 4 bottoms are fixed with cylinder end piece 1, piston rod is sleeved in the rifle body 4 by spring 16 and spring clamp nut 15, blower motor 33 is fixed in the motor seat 20 by bearing 22, pivot 17 is fixed together by the rotor of planet pin 18 with blower motor 33 in the rotation, motor seat 20 is fixed on the piston rod 19 by being threaded, and pivot 17 is sleeved in the piston rod 19 in will rotating, and rifle head 13 is fixed in the rotation on the pivot 17 by contiguous block 14.On motor seat 20, there is one just changeing gas passage 29 and a counter-rotating gas passage 31 respectively, a push rod 21 is arranged at the center of blower motor 33, push rod 21 1 ends withstand in the rotation in the pivot 17, the other end withstands on the spheroid 23, spheroid 23 just in time gets lodged in just to be changeed in the gas passage 29, rear end at motor seat 20 is set with a distributor 28 by end cap 25, have in the distributor 28 an inlet channel A30 just in time with motor seat 20 on just commentaries on classics gas passage 29 communicate, a baric area 32 is arranged between motor seat 20 and distributor 28, baric area 32 has an inlet channel 40 to link to each other with inlet channel A30, an inlet channel B27 is arranged on distributor 28 in addition, an air leakage hole 26 is arranged on the end cap 25, inlet channel B27 is controlled by switch 10, and the amount of the throughput of the throughput of inlet channel 40 and air leakage hole 26 must be less than the throughput of inlet channel B27.

As can be seen, only pull switch 10 from Fig. 2～4, inlet channel B27 just connects air pressure, connects air pressure among the inlet channel A30 always.In use, at first with nut precession rifle head 131～2 teeth, advance inwards again, promote spheroid 23 by pivot 17 in rotating and push rod 21, open and just change gas passage 29, blower motor 33 is just being changeed nut is tightened on the rifle head 13, pull switch 10 then, by the effect of starting handle 9, open pressure channel 8, because pressure channel 8 communicates with inlet channel B27.Open inlet channel B27 on the one hand, make among the inlet channel B27 and be full of air pressure, on the other hand in pressure channel 8 under the gas pressure, valve piston 37 is moved down, impel air supply pipe 3 to communicate with inlet channel A30, move down for the ease of valve piston 37, the sectional area of the G place ventilation of valve piston 37 must be greater than the sectional area at H place.Make in the air supply pipe 3 and be full of air pressure, promote cylinder piston 2 and move upward, oiling in the oil pressure district 34 between rifle body 4 and piston rod 19 promotes piston rod 19 and moves backward, pivot 17 and motor seat 20 moved together backward during piston rod 19 drove and rotates, and produced the riveted joint function.End cap 25 on motor seat 20 moves to bonnet 24 places, as can be seen from Figure 5, just in time open inlet channel B27, make and form a baric area 36 between distributor 28 and the end cap 25, the gas because air leakage hole 26 overflows, make air pressure decline among the inlet channel B27, air pressure decline in the pressure channel 8 also has a very little air leakage hole 38 in the reversal valve 7 on valve piston 37, under action of pressure, impel valve piston 37 to move up, air supply pipe 3 is cut off with inlet channel A30, gas is with the outside exhaust in the hole in the silencer 39 in the while air supply pipe 3, staking power is disappeared, and under the effect of spring 16, piston rod 19 moves forward, and promotes rifle head 13 and resets.Under the effect of the pressure of baric area 36, promote distributor 28 and move forward for motor seat 20 when resetting, the gas passage 31 that will reverse is connected with inlet channel A30, and blower motor 33 is reversed, and rifle head 13 is withdrawed from from nut.At last, by being distributor 28 to be moved the effect of disconnected qi of chong channel ascending adversely and air leakage hole 26 backward with respect to motor seat 20 in the baric area 32, baric area 36 is disappeared, state before distributor 28 returns to and uses.Wherein the throughput sum of the inlet channel 40 of the throughput of air leakage hole 26 and baric area 32 must just can make distributor move forward in the riveted joint process less than the air inflow of inlet channel B27.
