Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a single-shot device for a nailing machine, and more particularly to an adjustable single-shot device for a nailing machine.

[0002]

[Prior art]

 A nailing machine is a quick and convenient application and replaces the traditional way of hammering nails. There are various types of nailing machines. Among them are nailers with banding devices. Such a nailing machine has a band fuse protruding in front of an opening of the main body, and one end of the band fuse is located at a position corresponding to the trigger portion. When the band fuse makes contact with the workpiece surface and pushes the trigger, one injection operation is completed. Since a single injection operation of such a nailing machine must rely on a combination of a band fuse and a trigger portion, it is possible to avoid erroneous firing of the trigger portion due to an operation error. In other words, personal injury due to injection mistakes is reduced. However, since the vibration caused by the driving action of the nailing machine is quite large, it is easy for the nailing machine to jump or fall, and if the band fuse repeatedly contacts the surface of the workpiece, the nailing may occur. Along with dubbing, waste and damage to the surface of the workpiece occur.

[0003] Due to the drawbacks of using banding nailers, commercially available single shot nailers have appeared. For example, as shown in FIGS. 1 and 2, a lever portion 12 and a lever portion 13 are provided in the trigger portion 10 so as to correspond to the hand fuse 11, and the lever portion 12 is provided in the trigger portion 10. A sliding portion 15 and a sliding portion 16 are provided so as to correspond to the lever portion 13. If the hand fuse 11 pushes the lever portion 12 and the lever portion 13, the lever portion 12 and the lever portion 13 move, and the sliding portions 15 and 16 move while corresponding to the valve 14. Hitting action occurs. If the nailing machine is moved without releasing the trigger 10, the valve 14 has not returned to the predetermined position, so that the effect of entering air cannot be obtained. Therefore, even if the nailing machine repeatedly comes into contact with the workpiece, the nailing does not double. Release trigger 10 completely. A one-shot effect is achieved by returning the valve 14 to its original position and re-entering the air.

[0004]

[Problems to be solved by the invention]

 While the above-described conventional one-shot structure achieves the expected purpose, it is a common problem that the structure is complicated and the manufacturing difficulty is great. As shown in FIGS. 1 and 2, in the not-so-large trigger portion 10, not only the lever portions 12 and 13 are installed, but also the sliding portions 15 and 16 and the springs for pushing and moving the sliding portions 15 and 16 are provided. The equipment must be inconvenient in manufacturing, requires advanced manufacturing technology, has a high manufacturing cost, is not suitable for economic melito, and has to meet the demand for mass production. It is impossible to respond. Accordingly, it is a primary object of the present invention to provide an adjustable one-shot device for a nailing machine.

[0005]

[Means for Solving the Problems]

 According to the single-shot device for a nailing machine of the present invention for achieving the above-mentioned object, a plate portion installed on a trigger portion so that both lower sides correspond to focus, and a plate portion corresponding to an upper portion of the plate portion. As described above, the rotating rod, which is positioned above the trigger portion and has an arc surface on one side and a flat surface on the other side, engages with one end of the rotating rod passing through one side of the trigger portion, and A single-shot device for a nailing machine having a rotating portion for promoting interlocking, wherein the plate portion, the rotating rod, the rotating portion, and the trigger portion are mounted in combination with the nailing machine, and the plate portion is attached to the nail. Corresponding to the valve of the driving machine, the arc surface and the flat surface of the rotary rod correspond to the plate portion, and are in a single-shot, automatic injection use state.

[0006] By installing the plate portion and the rotating rod having the arc surface and the flat surface in the trigger portion, when the arc surface corresponds to the plate portion, the arc surface becomes a single shot state, and the flat surface corresponds to the plate portion. If you do, you will be hitting automatically. Therefore, with a simple structure and simple adjustment, it is possible to give the nailing machine two different motion models. Furthermore, once adjusted quickly and easily, the nailer will have a one-shot effect, increasing safety during use and allowing the nailer to hit automatically when the hand fuse is pressed.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 3, a single-shot device for a nailing machine according to an embodiment of the present invention includes a plate portion 2, a rotating rod 3, and a rotating portion 4. The lower sides of the plate portion 2 are provided in the trigger portion 5 so as to correspond to the pins 20, and the rotating rod 3 is positioned above the trigger portion 5 so as to correspond to the plate portion 2. The rotating part 4 is engaged with one end of the rotating rod 3 passing through one side of the trigger part 5, and forms an arc surface 30 on one side and a flat surface 31 on the other side. It encourages interlocking.

[0008] As shown in FIGS. 3 and 4, after the plate portion 2, the rotating rod 3, the rotating portion 4, and the trigger portion 5 are combined and mounted in the nailing machine, the band of the trigger portion 5 is displayed. A perforation 50 for penetrating the fuse 51 is provided. The plate portion 2 corresponds to the valve 52 of the nailing machine, and a spring 53 is mounted between the valve 52 and the plate portion 2. As shown in FIG. 5, when one end of the band fuse 51 does not hit the plate portion 2 even if the plane 31 of the rotating rod 3 is in contact with the plate portion 2, even if the trigger portion 5 is pressed, the plate portion 2 will not move. Hitting does not cause the action of hitting the nail.

As shown in FIG. 6, when the band fuse 51 hits the plate portion 2, the plate portion 2 hits the valve 52 by vibration and generates sufficient power, thereby driving the nailing machine into a nail. To complete. When the user keeps pushing the trigger part 5 and moves the nailing machine from the front of the work, the band fuse 51 does not hit the plate part 2 when returning to the original position. When the nailing machine is moved to a new position, as long as the nailing machine only touches the surface of the workpiece, the vibration caused by the band fuse 51 being pushed again against the plate portion 2 causes the nailing operation to be performed again when the valve 52 hits the valve 52. Is completed. If the nailing machine is repeatedly used in this manner, the nailing machine is automatically hit, so that a simple and quick use effect is exhibited.

As shown in FIG. 7 and FIG. 8, according to another embodiment of the present invention, the rotating part 4 (shown in FIG. 3) applies the arc surface 30 of the rotating rod 3 to the plate portion 2 and the arc surface 30. When the trigger 5 is pressed without the band fuse 51 hitting the plate portion 2, the plate portion 2 comes into contact with the valve 52 if the band surface 51 moves a little because the arc surface 30 protrudes. . However, the operation of the valve 52 is insufficient, so that the nailing machine cannot enable the nailing operation. When the band fuse 51 hits the plate 2, the vibration stroke of the plate 2 is sufficient to come into contact with the valve 52, and the nailing machine generates a nailing operation. When the nailing machine is moved, the band fuse 51 is returned to the original position, and the trigger portion 5 is not completely released, the plate portion 2 returns to the original position to correspond to the protruding arc surface 30 of the rotating rod 3. The valve 52 does not return and the air does not enter the nailing machine and wait. Even if the nailing machine touches the surface of the workpiece, the nailing operation does not occur. As long as the trigger portion 5 is completely released, the valve 52 enters the nailing machine again and waits, so that the next nailing operation can be executed.

[0011] Therefore, the present embodiment clearly shows a single-shot effect, and is used by adopting a single-shot operation method for a position where it is difficult to perform the operation or for a case where the safety is completely considered. The above safety is enhanced. According to the embodiment of the present invention, the simple rotating rod 3 can switch between a single operation and an automatic hitting operation by making the protruding arc surface 30 or the flat surface 31 correspond to the plate portion 2. It should be noted that the structure of the present embodiment is simple, and is very simple from the manufacture of the plate portion 2 and the rotating rod 3 to the installation in the trigger portion 5.

It should be noted that, as shown in FIGS. 9 and 10, in this embodiment, a locking portion 61 projecting above the plate portion 2 is installed in actual use, and By installing a recessed locking hole 60 on the front side of the trigger portion 5 for the plate member 2, the rotating rod 4 can be securely attached to the predetermined operating position of the plate portion 2, so that the rotating rod 4 No displacement occurs due to vibration caused by the use of.
