Description
Technical field
The utility model relates to a kind of switching mechanism that is used for pneumatic nail gun nailing mode.
Background technology
At present, the nailing mode that pneumatic nail gun is commonly used has singly continuously two kinds of nailing and co-continuous nailings.Single nailing continuously: the nail rifle can be by depressing guard to working face, and button is put trigger and continuous nailing repeatedly, but fastens trigger earlier, only is no more than nailing once then repeatedly when working face bump guard.The co-continuous nailing: the nail rifle can clash into guard and continuous nailing to working face then repeatedly by fastening trigger, also can be by depress guard to working face, and button is put trigger and continuous nailing repeatedly.
Fasten trigger earlier, then repeatedly can be fast but be not very accurate nailing to working face bump guard nailing, depress guard to working face earlier, button is put accurately nailing of trigger nailing then.Co-continuous nailing mode is earlier depressed guard to working face, when button is put the trigger nailing then, the nail rifle since reaction force may rebound, and if the nail rifle contact working face once more and you are just fastening trigger, second nail will be penetrated; Single nailing mode is continuously earlier depressed guard to working face, when button is put the trigger nailing then, the nail rifle since reaction force may rebound, and if the nail rifle contact working face once more and you are just fastening trigger, do not have nail yet and penetrate.Therefore when the nailing status requirement was higher, for guaranteeing safety, the user needed single nailing mode continuously; When the quick nailing of needs and status requirement when not high, the user needs the co-continuous nailing.In addition, nailing conversion regime now commonly used need be changed different triggers, and this kind mode is operated more loaded down with trivial details, and the user gets rid of part easily and causes following closely rifle and can not use when changing trigger.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the easy to use and safe switching mechanism that is used for pneumatic nail gun nailing mode.
The purpose of this utility model is achieved in that a kind of switching mechanism that is used for pneumatic nail gun nailing mode, it is characterized in that: this switching mechanism comprises the conversion knob, with the cam pin that is connected as a single entity of conversion knob, the conversion axle sleeve that is connected with the cam pin end, and the retainer spring and the locking ball that are connected successively with the conversion knob; This switching mechanism is arranged on the position that the plate machine of pneumatic nail gun is connected with installing hole on the housing.
Junction at above-mentioned conversion knob and described cam pin is provided with round boss, and the center of described cam pin does not overlap with the center of this round boss; Described transaxle cover is provided with round boss and conversion axle sleeve eccentric orfice, and the center of described conversion axle sleeve eccentric orfice does not overlap with the center of this round boss; Distance between the center line of the center line of the distance between the center line of the center line of described cam pin and coupled round boss and described conversion axle sleeve eccentric orfice and coupled round boss is identical; The end of described cam pin is disposed with flat side of cam pin and ring-shaped groove, and the flat side of described cam pin matches with the conversion axle sleeve boss of setting in the described conversion axle sleeve eccentric orfice, and described ring-shaped groove matches with the positioning retainer ring of setting; Described retainer spring matches with the inboard conversion knob locating hole that is provided with of described conversion knob.
The round boss that above-mentioned conversion knob and described transaxle put setting is two described installing hole matched in clearance on the outside and the described housing respectively, described conversion axle sleeve eccentric orfice is passed in the end of described cam pin, described positioning retainer ring is spacing with described conversion axle sleeve, the hole that the part between two described installing holes of described cam pin is passed described plate machine front end is matched in clearance with it, and the plate machine can rotate around cam pin; Center of rotation at the described conversion knob in the described housing upper edge of described conversion knob one side is symmetrical arranged 2 location pits, the semicircular steel ball sliding tray that is attached thereto is set between 2 described location pits, and the both sides of described locking ball contact with described retainer spring and described location pit respectively.
Rotate above-mentioned conversion knob described locking ball is moved to another described location pit from a described location pit through the steel ball sliding tray, the distance that the leading section of the plate handle spring that is connected with described plate machine moves forward or backward is 2 times of offset of described cam pin.
Its transfer principle of switching mechanism that is used for pneumatic nail gun nailing mode of the present utility model is similar to toggle, the leading section that drives the plate handle spring that is connected with trigger during rotation conversion knob seesaws, and process reaches button to trigger, puts State Selection and just can realize safe nailing whether depressing of guard again.Only need rotate the conversion knob during conversion nailing mode, just can carry out the conversion between single nailing continuously and the co-continuous nailing easily.
Therefore, the switching mechanism that is used for pneumatic nail gun nailing mode of the present utility model is rational in infrastructure, easy to use and safety.
