Description

Nail gun

The invention relates to a nail gun.

In general, the nail gun on the market includes a shrapnel, a pressure bar, a hook and a collision plate installed on the shell. The collision plate is respectively assembled with the shrapnel and the hook. When the pressure bar is pressed, the pressure bar will drive The shrapnel is deformed, and the hook still restricts the striker plate to prevent the striker plate from moving towards the nail outlet of the shell to store elastic energy. When the pressure lever is pressed to a firing position, the pressure lever will drive the hook and The collision plate is separated, and the collision plate is driven by the shrapnel and hits the nail outlet for nail extraction. The nail gun disclosed by TWI513555 belongs to this category.

However, because the impact force of the striker depends on the movement path of the striker and the elasticity coefficient and deformation size of the shrapnel, after the conventional nail gun is manufactured and shipped, the impact force of the striker is fixed and cannot be changed. Nailed on harder or softer objects can only have the same nail force, which is not convenient for use. Later, a nail gun with adjustable force appeared on the market, but it can only slightly change the top when the shrapnel is deformed. The fulcrum and the force adjustment are only between 10 and 30%, so the effect of adjusting the force is not good, users need to prepare nail guns with different strengths to match different objects, so there will be the cost of storing and buying other nail guns There are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive nail gun to solve the above problems.

To achieve the above object, the present invention provides a nail gun, which includes a housing, an impact member, a force storage component, a driving structure and an adjusting structure. The casing includes a nail outlet. The impact member is provided on the casing and can move toward or away from the nail outlet. The force storage component is movably arranged in the casing and is engaged with the impact member, and includes two force storage components. The driving structure includes a pressing rod pivotally arranged on the housing and a catching part, the pressing rod can be moved in a first position and a second position, and when the pressing rod is in the first position, the catch And the striking part engages with each other. When the pressing rod moves toward the second position, the driving structure forces the force storage component to deform and accumulate force. When the pressing rod moves to the second position, the locking part The impact piece is disengaged, and the impact piece is driven by the force storage assembly to move toward the nail outlet. The adjusting structure is arranged in the casing and can move a third position and a fourth position to be connected with the force storage component. Wherein, when the adjustment structure is in the third position, the force storage component only has the energy storage member far away from the nail outlet to catch with the impact member; when the adjustment structure moves to the fourth position, the The adjustment structure drives the force storage component to move, so that the two force storage elements are locked with the impact element.
