The present invention relates to a nail gun while being in the process of construction, and especially relates to a clamping device assembled to a nail gun.
The nail guns in the market are mainly provided for the uses in wood manufacturing industry, decorating materials industry, and decorating construction industry. Recently, the nail gun is made to form a specific structure for single use in order to process a specific construction.
Please reference to Taiwanese patent no. I440533, it disclosed a nail gun structure includes a gun body, a clamp set and a pneumatic driving set. The gun body has a trigger for shooting a nail. The clamp set is assembled with the gun body. The clamp set has a driven base and a clamp base. The clamp base pivots relative to the driven base. A stacked board is positioned on the clamp base. The pneumatic driving set is disposed between the gun body and the clamp set. The pneumatic driving set communicates with an air pressure source. The trigger moves along with the pneumatic driving set. Under this arrangement, when a user pulls the trigger, the pneumatic driving set drives the clamp base to pivot, so that the stacked boards are clamped between the clamp base and the driven base; thereafter, the nail is shot and nailed on the stacked board.
In the above mentioned structure, the clamp set and the pneumatic driving set are assembled to the gun body. The clamp set further includes a fixing plate and a connection rod. The fixing plate further includes a first assembling portion and a second assembling portion. An angle is angled between the first assembling portion and the second assembling portion. The first assembling portion is arranged on the gun body. The second assembling portion is assembled to one end of the driven base. One end of the connection rod is assembled to the stock of the gun body and the other end of the connection rod is assembled to the end of the driven base opposite to the second assembling portion.
The pneumatic driving set further includes a pneumatic valve, a first connection valve, a second connection valve, an adjusting valve, and a driving valve. The pneumatic valve is arranged at the fixing plate. The first connection valve is fluidly communicated between the gun body and the air pressure source. The first connection valve is connected to the pneumatic valve with a first pipeline. The second connection valve is connected between the pneumatic valve and the adjusting valve. The second connection valve is connected to the gun body with a second pipeline. The adjusting valve is connected to the gun body with a third pipeline. The driving valve is assembled to the driven base and connected to the pneumatic valve with a third pipeline. The driving valve is assembled on the driven base and connected to the pneumatic valve with a fourth pipeline so as to drive the clamp base the pivot and swing relative to the driven base.
However, as above mentioned structures, no matter what the clamp set or the pneumatic driving set is composed of many loose elements to form a complicated structure, once the loose elements are assembled to the nail gun, it is inconvenient to disassemble from the nail gun and the structure combined with the nail gun is hard to apply to other uses except construction of wooden pallets. The uses of the nail gun is limited. It is a first drawback thereof.
In order to provide for using in specific construction of wooden pallets, two complicated structures are assembled to the nail gun so that the heavy and complicated nail gun becomes more complicated. The difficulty and defective rate of assembling and manufacturing nail gun are increased. It is a second drawback thereof.
Because the clamp set and the pneumatic driving set which are complicated structures are assembled to the nail gun, the cost and price of each nail gun are increased higher so as not to be cost-effective. It is a third drawback thereof.
In view of the foregoing circumstances, the inventor has invested a lot of time to study the relevant knowledge, compare the pros and cons, research and develop related products. After quite many experiments and tests, the “clamping device for a nail gun” of this invention is eventually launched to improve the foregoing shortcomings, to meet the public use.
A main object of this invention is providing a clamping device for a nail gun. The fixing frame may be easily assembled and disassembled to the nail gun. It may be detached from the nail gun easily after finishing nailing and piercing the lay-up but not to influence and limit the use of the nail gun in other technical fields. And multiple functions of the nail gun may be achieved.
Another object of this invention is providing a clamping device for a nail gun, It is effectively to prevent the nail gun 100 from resulting in complicated structure and heavy weight due to hanging many elements. It has the effects of light weight and low cost and price.
