Description
Technical field
The present invention relates to a kind of nail gun.
Background technology
Nail gun is conventional hand-held tool, of a great variety, conventionally can be divided into pneumatic and electronic two kinds, and wherein the necessary outer compressed source of the gas of pneumatic nail gun, is used restricted.Electric nail gun comprises that the motor being placed in rifle body converts the reciprocating motion nail hitting transmitting nail of rifle mouth place's nail hitting bar to by the kinetic energy of rotation, and nail hitting efficiency is not high.
Chinese patent discloses a kind of active force of Compress Spring that motor is converted to by pinion and rack, relend and help the power of holding of Compress Spring to produce the moment strike of impulsive force realization to nail, but can only click, cannot impact continuously nail, cause its practicality to reduce.By flywheel rotational structure, when flywheel runs up, moment drives rifle pin, utilizes the inertia of flywheel to squeeze into nail, but flywheel speed does not catch up with when hitting fast continuously, causes the performance of nailing to reduce.
Summary of the invention
The problem that the present invention in use exists for solving prior art, provides a kind of simple to operate, the nail gun of dependable performance.
The technical scheme that the present invention solves existing issue is: a kind of nail gun, comprise casing, be arranged at driving mechanism on casing, be positioned at the reciprocating nail hitting bar in rifle mouth place, drive the transmission component of nail hitting bar accumulation of energy, drive the accumulating mechanism of nail hitting bar nail hitting, as improvement, described transmission component comprises the rotating shaft that connects driving mechanism, on rotating shaft, be fixed with travelling gear, be meshed with set teeth groove on nail hitting bar and four grab wheel, described four grab the sky that wheel is provided with a disengaging nail hitting bar grabs position, one is positioned at singly grabbing wheel it is grabbed extended end and is slidably arranged at this sky and grabs the chute that establish in a place on rotating shaft, described four grab wheel and singly grab and between wheel, are provided with back-moving spring,
The engagement of described travelling gear and a change gear, its gearratio is 2:1, change gear corresponding end-faces is provided with an extruding and singly grabs wheel and four and grab to take turns and coordinate complete four to grab the crushing block of wheel;
Complete four of described formation is grabbed wheel rotation, drives the accumulation of energy of nail hitting bar, described change gear crushing block with singly grab wheel and depart from, back-moving spring drives singly grabs wheel and resets, nail hitting bar is positioned at four and grabs bye and grab position, accumulating mechanism percussion nail hitting bar.
As further improvement, described driving mechanism comprises the drive motors being arranged on casing and the gear drive casing that connects rotating shaft.
As further improvement, described accumulating mechanism can be compression cylinder or stage clip, and described nail hitting bar is connected with constrictor or the stage clip of compression cylinder.
As further improvement, described rotating shaft is provided with ratchet, and a ratchet coordinating with ratchet is flexibly set on casing; Above-mentioned ratchet is arranged at four and grabs on wheel.
As further improvement, described four grab wheel place, room establishes chute and is provided with gathering sill.
As further improvement, at least one side of crushing block that wheel is singly grabbed in described extruding is provided with extruding inclined-plane or cambered surface.
The present invention compared with prior art, transmission component arranges and drives four of nail hitting bar to grab wheel, four grab wheel has gone up and has grabbed position, by suiting the crushing block of gear, controls and singly grabs wheel and four and grab to take turns and coordinate, and makes nail hitting bar complete accumulation of energy, and four, grab bye and grab the release moment nail hitting of place, position, its beneficial effect is that product of the present invention does not need the source of the gas that provides lasting, and the four lasting rotations of grabbing wheel convert nail hitting bar continuous shooting shooting stator to, and nail hitting efficiency is high, dependable performance, is used unrestricted.
