[Industrial applications]

 The present invention relates to a nailing machine used at a construction site or the like, which is capable of reliably and efficiently driving a nail even in a narrow place and out of reach of an angled nailing machine.

[0002]

[Prior art]

 In the conventional manual nailing work, manual nailing was extremely difficult in places where the hands could not be reached and the hammer could not reach in a narrow space. In order to improve this, recently, a nailing machine as shown in Fig. 1 has been put on the market. FIG. 1 shows a nailer according to the prior art. This nailing machine is composed of a casing, a piston rod slidably inserted in the casing, a magnet for holding a nail at the left end of the rod, and a handle that can be held by a hand at the right end. Further, the stroke portion and the contact surface are cut, and a stopper 5 (bolt) is provided to regulate the stroke of the rod. In order to use this nailing machine, first the magnet is used to attract and hold the nail, and then the rod is slightly lifted to pull the nail into the casing so that it can be held stably. It hits the material in place and holds the end of the casing with the left hand while striking the head of the handle with a hammer (not shown) in the right hand to drive the nail. This nailer must be hammered, and the handle cannot be held by hand. Also, since the casing is straight, it is not possible to drive nails diagonally. That is, (1) nails cannot be driven in by hand. (2) Therefore, always use a hammer. (3) It can be used only in a straight space through which the axis of the casing passes. There were some drawbacks such as (the nail cannot be slanted).

[Problems to be solved by the device]

 FIG. 2 is a cross-sectional view of a floor at a construction site using a nail driver. It is necessary to embed a sleeve 15 (for example, a paper sleeve or void) in the floor or the beam in order to penetrate the pipe hole before placing concrete. Therefore, it is necessary to fix the sleeve 15 to the form 16 with the nail 10. When the sleeve 15 is in the position a, it is possible to use a conventional nailing machine which is relatively short and straight, but when the sleeve 15 is fixed in the position b, the slab thickness is 200 to 300 mm. However, when using a conventional straight and short nailing machine, it is the actual situation where the worker crawls and nails. Furthermore, since it passes through the gaps in the bar arrangement, it was difficult to use the conventional straight nailing machine, and in some cases it could not be used. The present invention has the above-mentioned drawbacks (1) a very narrow place, a place that cannot be reached or reached (2) a place where a nail needs to be slanted by bending through a gap in the bar arrangement In addition, we propose a nailing machine with an angle that can significantly reduce man-hours. Description will be given below with reference to the embodiments shown in the drawings.

[Means for Solving the Problems]

 Shown in FIGS. 3 to 6 is an angled nailer according to the present invention. FIG. 3 is an overall assembly sectional view of the present invention, in which a piston rod 2 is slidably housed in a casing 1 and a handle 9 is provided at the right end. Inside the casing 3 of the knuckle portion, a spherical body 11 which is flexibly connected and transmits the striking force evenly is slidably provided, and a magnet 4 for attracting and holding the nail 10 is provided at the tip.

【Example】

 The method of using the nailing machine of the present invention will be described with reference to FIG. 3. First, the magnet 10 attracts and holds the nail 10. In order to hold the nail 10 in a stable manner, the handle 9 is pulled up until the striker 8'of the piston rod 2 hits the stopper 7, and a little further after hitting, the nail 10 is put into the casing 3 and stabilized upright. Next, the nail 10 is applied to a predetermined position of the mating material, and the handle 9 is held by hand and hit, or the hammer is hit with a hammer (not shown) to perform nailing. When the handle 9 is pulled up, the stopper 7 comes into contact with the casing 1 so that the piston rod 6 does not fall naturally and the nail 10 can be stably held at an appropriate position in the casing 3 if it is structured so as to be frictionally slidable. You can

FIG. 4 shows a structure for angling a nailing machine, and a striking force transmitting sphere 11 such as a spherical body, an elliptical sphere, or a cylindrical body is continuously connected by a wire 12 or the like, and a bolt b is connected to a piston 6 It has a structure in which it is screwed into the screw hole g and is continuously stored in the casing 3, and the striking force received by the piston 6 is bent through the spherical body 11 to be transmitted to the magnet 4 and the nail 10 is plunged. . FIG. 5 is a piston 6 and FIG. 6 is a single-piece drawing of the rod 2.

[Effect of device]

 1. Even if the reinforcing bars are arranged, the nail can be hammered by hand without using a hammer. 2. It can also be used for mounting inserts and mold work. 3. Workability and safety are improved. 1) You can work without crawling on the formwork or the reinforcing surface. 2) Can respond to changes in surrounding conditions. 3) Work clothes are not disturbed or dirty. 4) Factors leading to injury are reduced. 5) Helps prevent back pain because you do not use a hammer in an unreasonable posture. 4. It will be possible to save a lot of man-hours.
