Description

  The present invention relates to a nailing machine, and more particularly to a single shot / continuous batting switching device for a nailing machine.

In response to user demand, most of the current new nailers employ a single-shot and continuous-blow type switching mechanism in the trigger structure. Pulling the trigger only once can make a single shot, or after pulling the trigger once, different forms of hitting can be done, such as continuous hitting by a simple action of the safety device shaft touching or releasing the workpiece .
In the conventional form of the trigger switching structure related to the single shot / continuous hitting described above, when the adjustment switching device is attached to the trigger structure or the related parts of the trigger (for example, the end of the safety device shaft, trigger inner plate, etc.), In general, an adjustment switching device is used to perform a switching operation (switching, rotation operation, etc.). However, such a conventional structure must simultaneously consider various factors such as the operability, interlocking and mounting position of the switching mechanism, which ultimately results in a complicated structure that requires many parts and is wasteful. In addition to using a large space, it is very inconvenient to use.
Therefore, it is a consumer's expectation to improve the above-described problem of the trigger hitting type switching structure and to develop a new type structure that is more ideal and practical.

  An object of the present invention is to provide a single shot / continuous hit switching device for a nailer.

  In order to achieve the above-mentioned object, the present invention is configured such that a single operation plate is attached to the trigger valve of the nailing machine on the side facing the opening / closing valve shaft, and the rotation shaft of the operation plate is disposed at the trigger retracting portion. Therefore, the action part of the action plate faces the setting direction of the fixed part of the trigger, and the action part of the action plate swings in the setting direction of the opening / closing valve shaft when pushed by the end of the nailing machine safety device. A switching device is provided. The batting switching device is attached to the main body of the nailing machine. This batting switching device includes an operation control unit, which is attached to the main body of the nailing machine in a state of being movable in the vertical direction, and is installed at a position symmetrical to the operation unit of the operation plate. A hooking portion is provided on one side of the action part of the action plate of the action control part, and the catch part is located on the swing route of the action part of the action plate when the trigger is pulled. Thereby, an operation | movement part can be blocked | prevented. The other side of the operation control unit is a mounting unit and can be combined with a predetermined part of the nailing machine body. The impact switching device further includes an elastic restoring unit that supports the operation control unit. The elastic restoring unit causes the operation control unit to be internally contracted and to have an automatic restoration characteristic. Due to such a novel special design, the present invention makes the nailing machine trigger structure push the safety device shaft first in the switching operation of single shot and continuous hit, without using the switching parts, compared with the conventional technology. It is practical with improved operability and convenience by switching the single shot or continuous shot by changing the operation order, such as pulling the trigger from, or pulling the trigger and then pushing the safety device axis It has an inventive step. Furthermore, since the motion control unit and the elastic restoring unit mounted on the nailing machine main body have a simple structural design, high production efficiency and simple assembly can be realized, which can be said to be suitable for industrial use.

  In addition, by simplifying the structure of the motion control unit as a swing type motion control unit, it is possible to realize a simpler configuration and provide a product suitable for industrial use with excellent manufacturing efficiency and assembly efficiency. It is.

  The present invention provides a single shot / continuous hit switching device for a nailer.

  FIG. 8 shows a state in which the end portion 41 of the safety device 40 has moved to the stop position toward the operation plate 30 and the trigger 10 has not yet been pulled. In the course of this operation, the operation part 32 of the operation plate 30 swings according to the route L2 indicated in the drawing, and can get over the hook part 61B of the operation control part 60B. At this time, the inside of the operation plate 30 contacts the opening / closing valve shaft 20.

  As shown in FIG. 9, when the trigger 10 is pulled, the operation portion 32 of the operation plate 30 is fixed by the end 41 of the nailing machine safety device 40, and therefore the operation plate 30 rotates when the trigger 10 is pulled. A swing operation is caused on the side having the shaft 31 to contact the open / close valve shaft 20. Thereby, a striking operation is performed.

  As shown in FIG. 10, when the nailing machine safety device 40 is flipped and restored, the operation portion 32 of the operation plate 30 swings toward the original position without being supported. However, since the trigger 10 is in a retracted state at this time, the operation portion 32 of the operation plate 30 is shifted in the direction of the operation control part 60B. Therefore, when the operation portion 32 of the operation plate 30 tries to swing toward the origin, the operation portion 32 is blocked by the hook portion 61B of the operation control part 60, and the position of the opening / closing valve shaft 20 is also controlled. Subsequently, when the trigger 10 is released, the operation portion 32 of the operation plate 30 moves outwardly, moves away from the hook portion 61 and returns to the origin, and the trigger 10, the operation plate 30, the nailer safety device. All 40 are restored to the state of FIG. The single shot operation mode is realized by this mechanism.

  In the operation mode shown in FIG. 11, when the nailing machine safety device 40 is pushed after pulling the trigger 10, the operation part 32 of the operation plate 30 is shifted to the operation control part 60 </ b> B side in advance, so that the operation part 32 is a hook part. When the end part 41 of the nailing machine safety device 40 pushes the action part 32 of the action plate 30, the action part swings so as to retreat upward by pushing the action control part 60B. . At this time, the operation portion 32 of the operation plate 30 swings and presses the open / close valve shaft 20, so that a striking operation occurs. In this operation mode, the motion control part 60, the motion part 32 of the motion plate 30 and the safety device 40 move up and down at the same time. Therefore, when the user keeps pulling the trigger 10, the nailing machine safety device 40 is compressed / removed.
