Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a nail,
The present invention relates to an improvement of a portable portable nailing machine for automatically and continuously driving pins, clasps and the like.

[0002]

2. Description of the Related Art Conventionally, when nails, clasps, pins and the like are driven into a wall surface or a building material, an electric nail driving machine connected to an air compressor or a hammer is used to drive nails.

[0003]

However, a portable nailing machine used in connection with an air compressor must carry and move only the length of an air hose connecting the air compressor and the portable nailing machine. Could only be done. For this reason, there is a drawback that the working range of the work while holding the portable nailing machine is extremely narrow. If the length of the air hose connected to the compressor is lengthened, there is a disadvantage that the hose is entangled with a pillar, a tool in use, or the like and is damaged, and on the contrary, the range of action is narrowed.

Further, since the noise of the rotation of a motor such as an air compressor, the compression noise of compressing air, and the friction noise of the compressed air moving in the air hose are large, noises are generated in a work place, especially in interior finishing. In a closed space where the above-mentioned work is performed, there is a disadvantage that a work environment using a portable nailing machine becomes extremely poor.

Further, the conventional electric portable nailing machine is suitable for a wide range of work while being carried, but when it is electrically operated, the energy conversion efficiency is poor, so that the nailing force is poor, and conversely, the nailing force is increased. However, a large amount of electric power is required, so that the capacity of the battery becomes insufficient. If the capacity of the battery is increased to compensate for this, there is a drawback in that the weight increases and it becomes difficult to carry and carry a portable nailing machine.

Accordingly, the present invention is to provide a portable nailing machine that can carry and work anywhere easily and lightly without using an air compressor or a battery and that can strongly nail. It is the purpose.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a connecting member attached to a gripper of a nailing machine, in which compressed air, compressed liquefied air, and compressed liquefied gas are internally provided. And the like, and the discharge nozzle of the cylinder provided with the discharge nozzle is detachably attached to the connecting member of the grip portion.
