The main components of the staple driving tool 1 are a long pipe-shaped main body pipe 5 and an electric wire guide portion 2 attached to the tip thereof.
[0011]
The length of the main body pipe 5 is set to such a length that, when an operator holds it in his hand, the tip of the main body pipe 5 can reach the wiring location on the ceiling of the house. Inside the main body pipe 5, there is provided a structural portion that accommodates the staple 3 to be placed and pushes out the staple 3 for placement.
As shown in FIG. 1 (3), when the staple 3 is a staple laminate 3T in which a plurality of the staples 3 are laminated, the staples 3 are easier to handle than being separated. This is inserted from the tip of the staple driving tool 1 and accommodated in the main body pipe 5.
The structural portion for pushing out the staple 3 is a staple extrudate 4 and a screw rod 6, and the lower end of the screw rod 6 is connected to the engagement shaft 8 via a rotating shaft support 7 provided at the lower end of the main body pipe 5. Has been. The screw rod 6 and the engagement shaft 8 can be integrated.
[0012]
FIG. 2 is a view showing a lower end portion of the staple driving tool 1 of the present invention, and the reference numerals correspond to those in FIG. The cross section of the engagement shaft 8 is not a circle but an angled shape (eg, hexagonal shape). The reason is that the engagement adapter 9 is engaged and rotated, but the square is easier to transmit the rotational force.
The rotating shaft support portion 7 is a structural portion that is configured such that the connecting portion between the engagement shaft 8 (and that integrated with it) and the screw rod 6 can rotate relative to the main body pipe 5. This is configured by a known technique using a bearing or the like.
Returning to FIG. 1, when the engaging adapter 9 is mounted on the electric tool 10 and engaged with the engaging shaft 8 to operate the electric tool 10, the screw rod 6 rotates.
[0013]
FIG. 3 is a view showing the relationship between the staple extruded body 4 and the screw rod 6. The reference numerals correspond to those in FIG. 1, 41 is a ridge, and 42 is a screw hole. The staple extruded body 4 has a substantially cylindrical shape that is loosely fitted inside the main body pipe 5.

When the screw rod 6 is rotated in this state, the staple extruded body 4 screwed to the screw rod 6 moves upward or downward as indicated by an arrow D depending on the rotation direction of the screw rod 6. This is because, since the convex body 41 is fitted in the concave groove 51, the staple extrudate 4 cannot rotate together with the screw rod 6, and must move along the screw rod 6 screwed without stopping. Because there will be no.
[0015]
Returning to FIG. 1 (2), the wire guide portion 2 will be described. The skirt body 21 has a conical shape like a funnel. The guide cutout portion 24 is a cutout portion formed by cutting out a part on both the left and right sides of the skirt body 21 and has a size that can sufficiently receive the electric wire 11 to be laid.
The guide cutout 24 is desirably a deep cutout at the center. This is because the guide action is better. By receiving the electric wire 11 at the guide notch 24, it is possible to position the staple driving tool 1 so as to cross the central upper portion.
[0016]
FIG. 6 is a cross-sectional view showing the vicinity of the upper portion of the staple driving tool 1 of the present invention. Reference numerals correspond to those in FIG. 1, 13 is a stopper, 14 is a house construction body, and 25 and 26 are locking portions.
A main body fitting tube 22 extends from the rear part of the skirt body 21 and is fitted to the tip of the main body pipe 5. The locking portions 25 and 26 are protruding portions provided inside the upper and lower ends of the main body fitting cylinder 22, and the stopper 13 is a protruding portion provided on the outer periphery of the main body pipe 5. The spring 12 is a spring fitted to the main body pipe 5 so as to be positioned between the upper locking portion 25 and the stopper 13.
[0017]
When the main body pipe 5 is pushed upward against the elastic force of the spring 12 while the electric wire 11 is received in the guide cutout portion 24 and lightly pressed against the housing construction body 14, the tip of the main body pipe 5 gradually Approach the electric wire 11. When the most distal staple 3 arrives at the electric wire 11 and the screw rod 6 is rotated, the staple pusher 4 moves upward and pushes out the most advanced staple 3. A pin protrudes from the extruded staple 3 and is pierced (staple placement) into the housing construction body 14 to fix the electric wire 11. (The structure of the staple 3 from which the pin protrudes will be described with reference to FIG. 5.)
When the staple driving operation is finished and the main body pipe 5 is lowered, the spring 12 expands by the elastic force with the stopper 13 as a base point, and tries to return to the original state. Therefore, the main body fitting cylinder 22 is pushed up in the distal direction of the main body pipe 5. The push-up stops when the lower locking portion 26 comes up to the stopper 13 and is locked.
[0018]
FIG. 5 is a view showing the staple 3 according to the present invention. In FIG. 5, 31 is a base body, 32 is a leg part, 33 is a pin rear end fitting part, 34 is a protrusion, 35 is a pin, 35F is a pin front end, 35B is a pin rear end, and 36 is a screw rod insertion hole. is there.
FIG. 5A shows the staple 3 in a state where the pin tip 35F is not pushed out, and FIG. 5B shows the staple 3 in a state where the pin tip 35F is pushed out. FIG. 5 (3) shows a state in which a plurality of staples 3 are stacked, that is, a staple stacked body 3T.
[0019]
The staple 3 includes a columnar base 31 having a circular through hole 36 which is a circular through hole in the center, and two legs 32 protruding from one side surface of the base 31. The positions of the leg portions 32 are the positions of both ends of the diameter of the base 31. And the pin 35 is provided so that the base | substrate 31 and the leg part 32 may be penetrated. The pin 35 is made of metal, the pin tip 35F has a pointed shape so as to pierce the house construction body 14, and the pin rear end 35B has a shape having a wide area so as to easily receive a pressing force for pushing out.
[0020]
A pin rear end fitting portion 33 is provided at the front end of the leg portion 32. This is because the pin rear end 35B of the staple 3 laminated thereon is fitted to facilitate the lamination, and the pin 35 is provided below the pin 35. This is to transmit the pushing force applied from above to the upper pin 35.
The screw rod insertion hole 36 is simply a hole through which the screw rod 6 is inserted, and is not a screw hole in which a screw groove is cut. The convex body 34 is for fitting into the concave groove 51 of the main body pipe 5 shown in FIG. 4 and the like, thereby preventing rotation in the circumferential direction. Therefore, even if the screw rod 6 rotates, it does not rotate with it.
[0021]
When an upward push-up force is applied by the staple pusher 4 from below the staple laminate 3T as shown in FIG. 5 (3), the push-up force is transmitted from the pin 35 to the pin 35 being laminated. Since there is nothing above the pin 35 of the uppermost staple 3, only the pin 35 of this staple 3 is pushed out of the base 31 and the leg 32 as shown in FIG. It is pierced.
Although FIG. 5 shows an example of a staple having two independent pins 35, the present invention is not limited to this. For example, the two pin rear ends 35B of FIG. 5A may be connected to form a U shape. In short, any shape may be used as long as it has a convenient shape for stacking, the tip of the pin is hidden in the leg portion before being placed, and is pushed out and protrudes at the time of placement.
[0022]
Since the staple driving tool 1 is a tool for working in contact with an electric wire, the main body pipe 5, the electric wire guide portion 2 and the like are preferably made of an insulating material (for example, a plastic material) in order to prevent electric shock. Similarly, it is preferable that the base 31 and the leg 32 of the staple 3 are made of an insulating synthetic resin.
[0023]
【The invention's effect】
As described above, the present invention has the following effects.
(Effect of the invention of claim 1)
(1) It is easy to stack a plurality of staples, and handling is convenient. Since the tip end of the leg portion 32 through which the pin 35 is inserted is a pin rear end fitting portion 33 in which the pin rear end 35B can be fitted, a plurality of staples 3 are stacked to form a series of shapes. Can be easily done. Therefore, handling of staples is convenient.
(2) Only the first pin of the stacked staples can be projected.
When a force is applied to the rear end of the stacked staples 3, the force is transmitted to the pin 35 of the leading staple via the pin 35 of each staple 3, and only the tip of the pin 35 is projected. That is, only the pin 35 of the leading staple 3 that needs to be pierced is projected.
[0024]
(Effect of the invention of claim 2)
(1) Wiring to high places that are out of reach in the house is possible without using a stepladder.
The length of the staple driving tool 1 is such that it can reach a high place in the house when an operator standing on the floor holds it in his / her hand, so there is no need to perform it on a stepladder. . This eliminates the danger of dropping workers and tools from the stepladder, eliminates the labor and time of climbing up and down the stepladder, and improves work efficiency. Moreover, the glass of the house is not damaged by the stepladder.
(2) Since the stapling is performed with electric power, the fatigue of the worker is reduced.
Since the stapling is not performed with a hammer, but using the rotational force of the electric tool, the fatigue of the operator is reduced.
[0025]
(Effect of the invention of claim 3)
(1) It is possible to easily catch high-level electric wires.
The structure is such that the electric wire is searched with the funnel-shaped skirt body 21 having a diameter larger than the width of the electric wire 11 and guided to the guide notches provided on both sides of the skirt body 21, so that the electric wire 11 can be easily captured. I can do it.
(2) The leading staple can be accurately straddled over the electric wire.
Since the main body pipe 5 has a structure that allows the electric wire 11 captured by the electric wire guide portion 2 to advance to the nearest position, the leading staple 3 can be aimed so as to cross over the electric wire 11 accurately.
