  Embodiments of the present invention will be described with reference to the drawings.

  The driving tool 10 according to the present embodiment can be used for, for example, a floor jointing operation. As shown in FIG. 1, a tool main body 11 having a striking mechanism therein, and a rear side of the tool main body 11. , A trigger 14 operably provided on the grip 12, a magazine 13 connected in the vicinity of the tip of the tool body 11, and a nose portion provided so as to protrude from the tip of the tool body 11. 20.

  The striking mechanism built in the tool main body 11 operates by a known method, and operates the driver 15 by using forces such as compressed air, gas fuel explosion, and spring restoring force. As shown in FIG. 2, the driver 15 is movable in the direction of the nose portion 20 in order to drive out the nail, and moves in the driving direction of the nail when the striking mechanism generates an impact force. A nail set in the nose portion 20 is driven out.

  When the driving tool 10 is used, the grip 12 is grasped and gripped, and the trigger 14 is pulled. By this operation, the hitting mechanism described above is activated and the nail is driven out.

  The magazine 13 accommodates a connecting nail in which U-shaped staple nails are connected. This connecting nail is pressed forward by the pusher 16 so that the leading nail is sequentially supplied in the direction of the nose portion 20 (below the driver 15 before the driving operation).

  The nose portion 20 protrudes so as to be able to be pressed against the workpiece 30 and also functions as a part of the safety device in the present embodiment. That is, the nose portion 20 is provided so as to be able to reciprocate in the nail driving direction, and its tip protrudes from the tool body 11. When the nose portion 20 is pressed against the workpiece 30, the nose portion 20 moves upward relative to the tool body 11. When the nose portion 20 moves upward in this manner, a switch or the like (not shown) is pressed, the safety device is released, and the nail can be driven. In other words, the trigger 14 cannot be operated until the nose portion 20 is pressed against the driven material 30 and moves upward, or the nail is not driven even if the trigger 14 is operated.

  As shown in FIG. 3 and the like, an injection port 20a is formed at the tip of the nose portion 20, and a nail can be injected from the injection port 20a. The ejection port 20a is formed in a horizontally long shape because the staple nails are ejected one by one. In addition, the front surface and the rear surface of the nose portion 20 include a parallel surface 20b parallel to the nail launch direction and an inclined surface 20c provided on the tip side of the parallel surface 20b. The front and rear inclined surfaces 20c are inclined at an angle of about 45 degrees with respect to the nail launch direction, and the front inclined surface 20c and the rear inclined surface 20c intersect at a substantially right angle at the tip of the nose portion 20. ing.

  The nose portion 20 includes a front member 21 that supports the front side of the driver 15 and a rear member 22 that supports the rear side of the driver 15, which are coupled to each other by bolts 23. By joining the front member 21 and the rear member 22 in the front-rear direction, a nail injection path is formed between the front member 21 and the rear member 22. This injection path is opened at the tip to form an injection port 20a. When the striking mechanism is activated, the driver 15 reciprocates in the injection path to drive the nail.

  As shown in FIGS. 3 and 4, the front side member 21 includes a pair of bolt mounting portions 21a provided for mounting the bolts 23, a parallel surface portion 21b continuous to the tip side of the bolt mounting portion 21a, and a parallel surface portion 21b. And an inclined surface portion 21c continuous to the distal end side. The parallel surface portion 21b is a portion that forms the parallel surface 20b of the nose portion 20, and the front surface and the rear surface are formed in parallel to the injection direction of the nail. The inclined surface portion 21c is a portion forming the inclined surface 20c of the nose portion 20, and the front surface and the rear surface are inclined with respect to the nail injection direction. A groove 21d is formed vertically at the center of the rear surface of the front member 21, and a nail injection path is formed by covering the groove 21d with the rear member 22.

  The rear member 22 includes a pair of bolt mounting portions 22a provided for mounting the bolts 23, a parallel surface portion 22b continuous to the front end side of the bolt mounting portion 22a, and an inclined surface portion 22c continuous to the front end side of the parallel surface portion 22b. And comprising. The parallel surface portion 22b is a portion that forms the parallel surface 20b of the nose portion 20, and the front surface and the rear surface are formed in parallel with the injection direction of the nail. The inclined surface portion 22c is a portion that forms the inclined surface 20c of the nose portion 20, and the front surface is inclined with respect to the nail injection direction. In the present embodiment, the parallel surface portion 22b has a tapered shape when viewed from the rear, and the inclined surface portion 22c also has a tapered shape when viewed from the rear.

  Incidentally, as shown in FIG. 3B, the front end width W <b> 2 of the rear side member 22 is formed smaller than the front end width W <b> 1 of the front side member 21. Further, the rear member 22 has a color different from that of the front member 21. Specifically, the front member 21 is subjected to a surface treatment by plating to have a metal color, and the rear member 22 is subjected to a surface treatment by painting with black dyeing to be black. With this configuration, as shown in FIG. 5, it is easy to grasp the position of the injection port 20 a even when nails are driven into the tongue 31 of the workpiece 30.

  That is, when the floor material is fixed to the base material with a nail, the tip of the nose portion 20 is applied to the corner portion 32 of the tongue 31 of the driven material 30 and the nail is driven. At this time, the operator confirms the nail driving position while viewing the nose portion 20 from the rear. The front end width W2 of the rear side member 22 of this embodiment is smaller than the front end width W1 of the front side member 21 (that is, the front end width of the nose portion 20), and the injection port 20a is provided on the extension line of the rear side member 22. Therefore, the operator can work by predicting the position of the injection port 20a by looking at the rear member 22. In particular, in the present embodiment, the front end width W2 of the rear side member 22 is equal to the width of the injection port 20a, so that it is possible to work by accurately predicting the driving position. The rear member 22 has a color different from that of the front member 21 so that the rear member 22 can be easily recognized, and the position of the injection port 20a can be easily identified even in a dark place or the like.

  As described above, according to the present embodiment, the nose portion 20 includes the front member 21 that supports the front side of the driver 15 and the rear member 22 that supports the rear side of the driver 15, and the rear member. The front end width W2 of the front side member 21 is smaller than the front end width W1 of the front side member 21, and the rear side member 22 has a color different from that of the front side member 21. According to such a configuration, by increasing the tip width W1 of the front member 21, the tip width of the nose portion 20 is increased, and the posture at the time of driving can be stabilized. Further, since the rear member 22 has a small tip width and a different color, the position of the injection port 20a can be determined using the rear member 22 as a mark. Therefore, it is possible to achieve both stabilization of the posture at the time of driving and confirmation of the injection position. Moreover, since the mark display of the injection position can be realized without forming unevenness on the surface, the uneven shape does not damage the surface of the floor material or the like.

  In order to make the rear member 22 and the front member 21 have different colors, at least one of the rear member 22 and the front member 21 is subjected to a surface treatment by plating or painting. According to such a configuration, unlike a seal, for example, it is not easily peeled off, so that it is possible to improve the durability of the mark display at the injection position.

  Moreover, since a color difference is realized by combining a plurality of members (the front member 21 and the rear member 22), either one of the members is partially colored or painted in order to represent the injection position. There is no need to paint separately. In particular, it is difficult to partially change the color of plating, black dyeing, etc., but it is only necessary to apply different surface treatments to the front member 21 and the rear member 22, thereby reducing the production cost without increasing the number of work steps. It can be suppressed.

  Moreover, the rear side member 22 is provided with the tapering shape which becomes narrow toward the injection port 20a. According to such a configuration, since the width of the rear member 22 is narrowed toward the injection position, it is possible to make it easier to aim at the nail driving position.

  Further, the front end width W2 of the rear member 22 is equal to the width of the injection port 20a. According to such a configuration, the position of the injection port 20a can be known more accurately.

  Note that the shape of the rear member 22 is not limited to the shape of the above-described embodiment, and can be appropriately changed according to the nail used for the driving tool 10 or the like. For example, as shown in FIGS. 6 and 7, only the parallel surface portion 22b is tapered when viewed from the rear, and the inclined surface portion 22c does not have to be tapered. Even in such a shape, since the rear member 22 is formed in a tapered shape as a whole, the width of the rear member 22 is narrowed toward the injection position, making it easy to aim at the nail driving position. be able to.

  In the above-described embodiment, the parallel surface portion 21b and the inclined surface portion 21c of the front member 21 and the parallel surface portion 22b and the inclined surface portion 22c of the rear member 22 are not provided with protrusions, and the surface is flat. . However, as shown in FIG. 8, a protrusion 22 d may be provided on the rear surface of the parallel surface portion 22 b of the rear member 22, and the protrusion 22 d may have a color different from other portions of the rear member 22. According to such a configuration, the position of the injection port 20a can be made conspicuous by using the protrusion 22d.
