Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a nail driving tool,
More specifically, the present invention relates to a nail driving tool for supporting a nail or the like in an appropriate posture when driving the nail into wood, concrete, mortar, or another object.

[0002]

2. Description of the Related Art Conventionally, when driving a nail or the like into an object, an operator supports the nail or the like with the finger of one hand so that the tip of the nail faces the object, and a hammer held in the other hand. A method of hitting the head of such a nail was used.

[0003]

In the conventional method described above, for example, when the object is a nail, the hammer to be swung down hits the head of the nail or the like from a direction exactly along the longitudinal direction of the nail. However, the nail head is often hit obliquely with respect to the longitudinal direction of the nail. In such a case, since the nail is only held in a posture with respect to the object with the operator's finger, particularly when the object to which the nail is driven is a hard material such as concrete or mortar,
The nail is easily bent in the middle of the driving, and the driving of the nail is not completed. In some cases,
In some cases, it was necessary to prepare a new straight nail many times and be forced to start over. (In this case, it may be necessary to remove the bent nail from the object before the whole is driven in. Many). In addition, since a part of the impact force generated between the hammer and the nail that is swung down is applied to the finger supporting the nail as strong vibration, the force for swinging the hammer must be adjusted. However, there was a problem that it could not be sufficiently increased. Furthermore, when the fall point of the hammer for driving is shifted by force majeure, there is a disadvantage that the finger supporting the nail is easily hit. An object of the present invention is to provide a nailing tool in which a nail is hard to be bent in the middle of driving, even in a case where an object into which the nail is driven is made of a hard material such as concrete or mortar, in view of the above-mentioned disadvantages found in the conventional method exemplified above. Is to provide.

[0004]

In order to achieve the above-mentioned object, a nail driving tool according to the present invention is characterized in that a nail having a longitudinal direction and a nail are disposed in front of the main body. A nail locking mechanism that can be locked in a facing position, and a moving piece provided so as to be relatively movable only along the longitudinal direction with respect to the main body, and a hit portion of the moving piece (from a hammer or the like). Based on the impact force along the tip direction of the received nail, the action part of the moving piece pushes the nail forward from the main body through the nail head, and the nail can be driven.

[0005]

Due to the above-mentioned features, in the nailing tool according to the present invention, the posture of the nail to be locked is kept constant by the nail locking mechanism, and the hitting portion of the moving piece is hit. Since the moving force of the moving piece is limited to the relative movement along the longitudinal direction of the main body, the striking force transmitted from the hammer swinged down to the nail moves the nail head from the direction exactly along the longitudinal direction of the nail. Since the nail is hit, a peculiar effect that the nail is hard to be broken during the driving is generated. Further, when performing the operation of maintaining the posture of the nail with respect to the object correctly, the operator may perform this operation by holding not the nail itself but one part of the main body that holds the nail. As a part, you can select a position that is far enough away from the hitting part of the moving piece, which is the target point for swinging down the hammer, so that you may accidentally hit your finger during the driving work hard. Also,
Under the same circumstances, the impact force generated between the hammer and the nail that is swung down is transmitted to the finger only through the moving piece or the main body, so it is not felt as a strong vibration, and therefore, the force to swing the hammer down It is not necessary to adjust in this sense, and the nail can be driven with a strong force from a driving stage in which the nail has not yet entered the object. As a result, a specific effect that the driving efficiency is improved is produced. By using the nailing tool according to the present invention, a nail can be quickly and easily driven into a hard concrete wall or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. The nailing tool shown in FIG.
A tubular guide support tube 3 (an example of a main body) made of steel or the like having a longitudinal direction is provided. In addition, near the tip of the guide support tube 3, there is provided a nail locking mechanism capable of locking the nail 7 with respect to the guide support tube 3 with the tip of the nail 7 facing forward of the guide support tube 3. I have. Guide hole 3 provided in the cylinder of guide support tube 3
B has a moving rod 4 made of steel or the like (an example of a moving piece)
Are supported so as to be relatively movable only along the longitudinal direction of the guide support tube 3. One end of the moving rod 4 is provided with a recessed groove 4A for receiving the head 7A of the nail 7, and the other end is a part to be hit by a hammer or the like. Therefore, when the hitting portion of the moving rod 4 is hit in the direction of the tip of the nail 7 to apply an impact force, the action portion of the moving rod 4 (which is equivalent to the concave groove 4A) guides the nail 7. The nail 7 can be driven into the target object by pushing it forward from the support tube 3.

Further, the nailing tool shown in FIG. 1 is provided with a pair of handles 1 and 2 similar to the handle of a normal nipper, and the handles 1 and 2 are each provided with a circular projection 1A. , 2A
Are swingable with each other through through holes formed in the holes. Also, from the circular projection 1A of the handle 1, an "L" -shaped pressing piece 1B is formed.
Similarly, an L-shaped push piece 2B extends from the circular projection 2A of the handle 2 in the same manner. On the other hand, a pair of projecting pieces 3
A, 3A extend at a right angle, and the circular protrusions 1A, 2A and the protruding pieces 3A, 3A swing with each other in a state where the circular protrusions 1A, 2A are sandwiched between the protruding pieces 3A, 3A. It is fixed by bolts 5 and nuts 6 as much as possible. Guide support tube 3
A semicircular groove 3C capable of receiving a part of the nail body of the nail 7 is provided in the vicinity of the distal end of the nail 7, and a through hole 3D is provided in the proximal end side. When the operator grips the pair of handles 1 and 2,
The handles 1 and 2 swing around the axis of the bolt 5, and accordingly, the pushing piece 1B moves in the through-hole 3D to act on the guide groove 4B of the moving rod 4, thereby moving the moving rod 4 into the guide hole. By pressing against one part of 3B, the movement of the moving rod 4 with respect to the guide support tube 3 is regulated, and at the same time, the pushing piece 2B moves toward the semicircular groove 3C, where the nail 7 is locked. Therefore, the pushing piece 1B cooperates with the guide groove 4B of the moving rod 4 to constitute a moving rod locking mechanism, and the pushing piece 2B is formed as a semicircular groove 3C.
Cooperates with to form a nail locking mechanism. The moving rod locking mechanism can prevent the moving rod 4 from vibrating in the guide hole 3B due to the impact force given by the hammer for driving the nail, thereby reducing the noise level at the time of driving the nail. Advantageously reduced. In a similar situation,
The work amount obtained from the hammer can be more efficiently converted only to the nail driving action (that is, it is difficult to convert the work into a work that causes the moving rod 4 to greatly oscillate or a work that generates noise). Can nails.

(Function as Nail Supporting Means) When driving a nail into a wall or the like, first, the handles 1 and 2 are opened in the direction of the dotted arrow in FIG. By this operation, the pushing piece 1B is inserted into the through hole 3
The moving rod 4 can move freely in the guide hole 3B because it escapes from D, while the pushing piece 2B separates from the semicircular groove 3C and is large enough to insert a nail near the nail locking mechanism. An empty space is formed. In the above state, the nail 7 is
A is housed in the recessed groove 4A, and the nail body of the nail 7 is in a semicircular groove 3C.
Then, the moving rod 4 is positioned so that the tip of the nail 7 projects forward from the semicircular groove 3C by an appropriate length.
Is moved to push the nail 7, and furthermore, the guide groove 4B is inserted through the through hole 3.
D, and then, when the handles 1 and 2 are narrowed in the direction of the solid line arrow in FIG. 2, as described above, the pushing piece 1B regulates the movement of the moving rod 4 and the pushing piece 2B Is securely locked on the semicircular groove 3C.

Then, the tip of the nail 7 is applied to the object while the force in the direction of the solid arrow in FIG. 2 is applied to the handles 1 and 2, and the hitting portion of the moving rod 4 is hit with a hammer (not shown). With the pushing force of the mallet, the moving rod 4 moves in the guide hole 3B while keeping contact with the inner surface of the guide hole 3B, and drives the nail 7 into a wall or the like.
At the time of this driving operation, the head 7A of the nail 7 is sandwiched by the recessed groove 4A of the moving rod 4, and the nail body of the nail 7 is kept pressed into the semicircular groove 3C by the pushing piece 2B. Therefore, even if the nail 7 is long, it is difficult to bend during driving. This is especially because the nail is straightened by the nail locking mechanism consisting of the pushing piece 2B and the semicircular groove 3C during the driving operation.

(Function as a hammer) The nailing tool according to the present invention can also be used as a hammer for nailing. In this case, in particular, as shown in FIG. The moving rod 4 is moved so that the amount of protrusion from the moving rod 3 is minimized. In other words, the moving rod 4 is struck while the distal end of the moving rod 4 is in contact with the distal end of the guide support tube 3 and the pushing piece 2B. Just hit the nail with the club.

(Function as a nail puller) A support 301 having a curved surface is integrally provided on the back surface near the distal end of the guide support tube 3, and as shown in FIG.
By using 01 as a fulcrum of the leverage principle and using the nail locking mechanisms 2B and 3C as points of action, a nail or the like can be pulled out. In this case, the head 7A of the nail 7 is sandwiched between the recess 4A of the moving rod 4 and the inner wall surface of the guide support tube 3, and the neck of the nail 7 is
Since the nail pulling operation is performed while maintaining the state of being sandwiched between B and the semicircular groove 3C, it is possible to pull out the nail in the middle of driving reliably and easily.

(Function as Scissors) In the nailing tool according to the present embodiment, the blades 101 and 102 are provided on the bases 1 of the handles 1 and 2 with respect to the circular projections 1A and 2A, respectively. Can be used as cutting scissors. That is, the blade part 10
When a cutting target such as a wire is positioned between the blades 1 and 102 and the handles 1 and 2 are swung, the blades 101 and 102 are cut.
The wire is cut by the shearing action obtained by the above.

[Other Embodiments] <1> In the above embodiment, the mechanism for driving the nail into the object has been described based on the effect that the moving rod 4 moves in the guide hole 3B by a hammer. The operator supports the handles 1 and 2 so as to hardly restrain the vertical movement of the guide support tube 3 itself, and applies the impact force of a hammer to move the moving rod 4 in the guide hole 3B. The nail 7 may be driven into the object without necessarily performing the action of performing the operation (that is, in a state where the moving rod 4, the guide support tube 3, the handles 1, 2 and the nail are all integrated). .

<2> The moving rod locking mechanism or the nail locking mechanism is not limited to the locking mechanism interlocked with the swinging operation of the handles 1 and 2 as in the above embodiment. You may comprise as an independent locking mechanism. In this case, in either of the moving rod locking mechanism and the nail locking mechanism, for example, an operating position in which the moving rod 4 is brought into contact with the moving rod 4 and pressed against the guide support tube 3, and a non-operating position separated from the moving rod 4. The movable piece may be supported on the guide support tube 3 and the movable piece may be biased to the operating position by a spring or the like. In this case, the handles 1 and 2 do not need to be swingably provided at least for the purpose of locking a moving rod or a nail.
