Description

Novel nail knocking gun

Technical Field

The utility model relates to a hand tool technical field specifically says a novel strike nail rifle.

Background

The nail knocking gun is also called a manual nail knocking gun, is widely applied to the fields of buildings, decoration, furniture manufacturing, advertisement decoration and the like, and is used for knocking nails into a wall or a wood board to finish the purpose of fixing the two objects. The nail knocking gun is used for knocking nails, so that the construction efficiency can be improved, and personal injury to operators is avoided. The prior art nail knocking gun generally comprises a shell, a slide way arranged in the shell, a punching needle in sliding fit in the slide way, and a nail feeding box connected with the shell, wherein the nail feeding box is used for automatically feeding a type nail to the position right below the punching needle, and the punching needle is provided with a knocking part exposed outside the shell and used for knocking by a hammer. For example, a patent application with publication number CN206123571U and name of manual nailing gun is disclosed on the website of the national intellectual property office. The nailing gun strikes a nail out of a nailing hole through the striking of the claw hammer on the striker, and finally strikes a target position, and when next striking nailing is prepared, the claw of the claw hammer is clamped at the extension section of the reset rod and exerts force upwards, so that the striker is driven to move upwards to reset to prepare for next striking type nail. The firing pin of the nailing gun with the structure needs to be manually reset after punching nails, so that the nail punching efficiency is low and the operation is troublesome; in addition, when the hammer is used for knocking the firing pin to enable the firing pin to punch the nail into the object to be fixed, if the force is small or the object to be fixed is hard, the nail cannot be punched into the object to be fixed at one time, the firing pin can move outwards due to self gravity or other elasticity at the moment, even the nail punching end of the firing pin moves to the upper side of the type nail, if the firing pin is knocked again, the firing pin can punch other type nails down to cause the nail clamping, or a gap is reserved between the nail punching end of the firing pin and the type nail which is not knocked into the object to be fixed, the type nail which is not knocked into the object to be fixed can be bent during knocking, and the nailing effect is poor.
