The same gate nail of nail, the front end of storage nail cavity are equipped with nail mouth, and the rear portion of storage nail cavity is arranged equipped with flexibly pushing tow gate
The delivery device of nail, so that the front end of nail be made to be close to the front side of storage nail cavity, at this time foremost in gate nail always
One gate nail is located just in nail mouth.And beater mechanism includes rotatable handle, nailing piece moving up and down, nailing
On piece connects elastic element, and handle is connected by effort-saving mechanism with nailing piece.When user holds handle with a firm grip, province can be passed through
Force mechanisms move up nailing piece, correspondingly, put aside elastic force with deformation of elastic element that nailing piece is connected；When handle quilt
When holding with a firm grip to a certain extent, nailing piece is moved to extreme higher position, to form maximum displacement, effort-saving mechanism and nailing piece at this time
It disengages, the elastic force of elastic element is released, so that the nailing piece of frame body front end be driven quickly to move down, and then will be located at and to follow closely
Gate nail in mouthful is gone out downwards.
Due to the difference of the material of the manipulating object of gate nail, that is to say, that the hardness of manipulating object can be varied.
And existing crimping nail gun have following defects that when hold with a firm grip handle when, the disengaged position of effort-saving mechanism and nailing piece immobilizes,
To make the maximum displacement value of nailing piece fix, correspondingly, deformation caused by elastic element is identical.That is, bullet
The elastic force that property element is put aside is fixed and invariable.In this way, gate nail can go out when the material for encountering manipulating object is relatively soft
Now because the impact force of nail gun is excessive, to lead to fall into manipulating object too deep, serious or even nailing piece can be made on manipulating object surface
Go out ugly trace.When the material for encountering manipulating object is harder, gate nail will appear due to the impact force of nail gun is inadequate
It can not be completely into manipulating object, to cause the failure of nailing.Analogously, when using different types of gate nail,
Its required impact kinetic energy is also different, is equally easy to appear phenomena such as nailing is too deep or excessively shallow.That is, user
It needs to prepare and carry more crimping nail guns different size and needs the material according to manipulating object during operating with
