Detailed description of the invention

Below in conjunction with accompanying drawing the invention will be further described explain.

Nailing gun, including the connection handle 2 connected successively, sliding sleeve 1, trocar sheath 4 and nail sleeve pipe 10, sets in described connection handle 2 There are two cavitys, the first cavity to connect outside assister bar and adapt to the use of various height, place nylon cushion 13 in the second cavity, hitting Buffer when sending out, nylon cushion 13 has been placed mainspring 17.Described sliding sleeve 1 is spirally connected fixing with connection handle 2, sets in the middle part of sliding sleeve Laterally zygomorphic stopper slot 24, stopper slot 24 interpolation is had to connect return pin 15, this return pin slide anteroposterior in stopper slot；Described cunning Set 1 is slidably matched with trocar sheath 4, has a cavity, arrange return spring 16 in described cavity between trocar sheath and return pin, should Trocar sheath is supported in return spring 16 one end, and the other end supports return pin 15；Sliding sleeve 1 outer cover connects decorative tube 3, this decorative tube be connected Handle 2 touches, and the two ends of return pin 15 contact the inner surface of this decorative tube.

Described trocar sheath 4 is spirally connected fixing with nail sleeve pipe 10, and centre is provided with sheathing 8, and be slidably connected in trocar sheath striker set Pipe 5, this striker sleeve pipe is divided into two sections, the storage nail 23 in wherein one section of small diameter stretches into nail sleeve pipe, and with storage nail inwall Being slidably matched, another section of larger diameter is slidably matched with outer sleeve inner wall；Be slidably connected in described striker sleeve pipe 5 percussion dress Putting, described percussion lock includes beating shaft 6, and beating shaft front portion is fixing connects striker 7, and mainspring 17 is supported at rear portion；Striker 7 point End surface is provided with Baltimore groove 71, it may have certain cushioning effect, and can increase percussion area, it is ensured that percussion success rate；Percussion Axle is provided with lock pin 11, and sliding sleeve 1 inner surface is fixedly installed the sliding sleeve pipe key 12 supporting this spring catch；Described beating shaft 5 is corresponding solid The position of lock pin 11 is provided with lock pin groove 18, and the position of the corresponding sliding sleeve pipe key 12 of striker sleeve pipe 5 is provided with pipe key chute 21, sliding sleeve pipe Key slides in pipe key chute, and top pressure lock pin in sliding process, and described lock pin and splenium position, pipe key chute top are ball Planar, dome shape design can smooth offset, and prevents stuck；Diameter it is provided with more than pipe key chute 21 both sides in the middle part of pipe key chute 21 The circular hole 22 of groove width, circular hole 22 diameter is overall more than lock pin 11 spherical diameter stuck lock-pin 11 ejects lock pin groove 18；Beating shaft 6 Front portion is provided with needle guard hole and screw hole, and this screw hole is vertical with needle guard hole and connects, and striker 7 inserts this needle guard hole, and by with The screw 20 that screw hole coordinates is fixed, and makes junction gapless between striker and beating shaft, and axiality is high, will not produce partially Move, it is ensured that moment percussion force on the same axis, increases percussion success rate.

Set the two-stage structure described in two chamber correspondence striker sleeve pipes in described striker sleeve pipe 5, the first chamber corresponding its In one section of small diameter, and be slidably matched with striker, another section of corresponding second chamber of larger diameter, and slide with beating shaft and join Close；The joining place of striker sleeve pipe 5 first chamber and the second chamber sets a tubaeform chamber, and described beating shaft 6 front portion is to should Tubaeform chamber arranges round platform portion, and this round platform portion and tubaeform chamber leave gap.

Nail sleeve pipe 10 body is communicated with inclined hole 25, described connection inclined hole 25 connection storage nail 23 and nail sleeve pipe outer tube Face, is provided with a groove at outer tube surface, and intercommunicating pore connects this groove and storage nail, during percussion nailing shell fragment, can produce certain making an uproar Sound, this intercommunicating pore possesses the effect of certain noise elimination and heat radiation.Storage nail 23 is straight-tube shape structure, and striker sleeve pipe 5 is in storage nail Interior art skating, when nailing shell fragment percussion quantity is many when, storage nail has the accumulation of certain gunpowder flue dust, now this straight tube Shape structure facilitates cleaning, prevent and external friction interference and reduce percussion success rate.Nail sleeve pipe 10 connects protective cover 19, this protection Covering and fixed by jump ring 14, on nail sleeve pipe, the side of protective cover is socketed front gland 9, sheathing 8 successively.

During work, first nail shooting pill is put into the nail sleeve pipe of nailing gun, nail shooting pill is directed at the matrix location that need to fix On.Assister bar promotes nailing gun, when connection handle and sliding sleeve forward slip, mutually pushes up pressure at nail shooting pill and striker sleeve pipe, hits Mainspring is compressed, and during sliding sleeve forward slip to sliding sleeve pipe key, sliding sleeve pipe key top is pressed onto beating shaft lock pin, when beating shaft lock pin When being pushed up pressure completely by sliding sleeve pipe key, beating shaft is under the active force of mainspring, and moment makes beating shaft top pressure striker to nail sleeve pipe Interior nail shooting pill tablet clashes into, and nail shooting pill tablet produces fierce blast when clashing into, and nailing is fixed by the thrust of explosion time moment On required fixing matrix.After firing successfully, under the bounce effect of explosion time, press return pin by return spring top, return Position pin drives beating shaft and striker, and original position when connection handle and sliding sleeve are also reset to percussion lock.Return pin is all the time in limit Slide in the groove of position, be unlikely to excessively to fire or during return bounce excessive and hurt people, it is ensured that when percussion or return Safety.
