Technical Field

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

Background

The nail knocking gun is also called a nailing 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 body or a wood board to finish the purpose of fixing the two objects. Traditionally, people hold between the fingers the nail when beating the nail to wall body or plank, hold between the fingers the nail on one hand, hold the hammer on the other hand and strike the nail to in making the nail go into fixed object, this kind of nail mode of adopting the hand to hold between the fingers the nail requires operator's nailing technique higher, if the misoperation, can cause the injury to operator's finger. At present, people generally adopt a nail knocking gun to knock 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. If a patent application with the publication number of CN206123571U and the name of manual nailing gun is disclosed on the website of the national intellectual property office, the structure of the nail gun comprises a gun nozzle, a cartridge clip, a limiting reset device and a firing pin, wherein a nailing hole is arranged in the middle of the gun nozzle, a nail feeding hole is formed in one side surface of the gun nozzle and communicated with the nailing hole, the cartridge clip comprises a fixed cartridge clip and a movable cartridge clip, the inner end of the fixed cartridge clip is fixed with the side surface of the gun nozzle, on which the nail feeding hole is formed, a nail loading groove is formed in one side of the fixed cartridge clip and matched and communicated with the nail feeding hole, the movable cartridge clip is movably arranged in the nail loading groove, the inner end and the outer end of the movable cartridge clip are matched and level with the inner end and the outer end of the fixed cartridge clip, a spring, a top push rod and a top head are arranged in the movable cartridge clip, a baffle is arranged at the outer end of the movable cartridge clip, one end of the spring is abutted against the top push, the ejector push rod is matched with a collision block corresponding to the ejector, the ejector is located in the nail loading groove and slides forwards and backwards in the nail loading groove, a clamping device is arranged on the fixed cartridge clip and used for clamping the baffle, the striker comprises a nail punching section and a knocking section, the nail punching section is arranged in the nail punching hole, the knocking section is exposed out of the nail punching hole, a limiting section is arranged between the nail punching section and the knocking section, and the overall dimension of the limiting section is larger than that of the nail punching hole; set up spacing resetting means between section of knocking and rifle mouth, spacing resetting means is including wearing to establish and fixing the release link in the radial downthehole of section of knocking, with release link body coupling wear to establish the guide bar in the guide hole in the spacing seat on being fixed in the rifle mouth, the guide bar makes a round trip synchronous motion along with the firing pin in the guide hole, is equipped with the gag lever post at the tip of guide bar, the distance between gag lever post to the spacing seat is less than the length of punching the nail section, the release link tip passes the radial hole of section of knocking and outwards has the extension section of certain length. 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.
