Abstract

(57) [Abstract] [Purpose] The present invention relates to a driving machine with an improved structure in the vicinity of the injection port. The purpose of the present invention is to provide an elastic restoration material or a stop passage in the stop passage just before the injection port. By providing a stopper stopper capable of advancing and retracting at the position, it is possible to prevent the stopper from entering when the pushing load of the feeder is 0 or extremely weak and improve the safety. [Structure] Immediately before exiting from the stopper passage 3 to the injection port 1, elastic stoppers or stopper stoppers 2 capable of advancing and retracting in the stopper passage are provided at both ends of the injection port 1. Connecting stopper 4 with feeder 10
When pressing, the stopper stopper 2 is deformed or retracts from the stopper passage 3, and the connecting stopper 4 enters the injection port 1. Connection stopper 4 when the pushing load of the feeder is 0 or extremely weak
Is locked by the stopper stopper 2 and cannot enter the injection port 1 due to its own weight of the coupling stopper 4 or vibration during driving.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a driving machine that pushes a connecting stopper from the rear to sequentially supply a leading stopper into an injection port. More specifically, the structure near the injection port is improved.

[0002]

[Prior art]

 As shown in FIG. 3, each fastener is connected in a straight line so as to be parallel to the axis. A driving machine having a magazine 8 for accommodating the fastener 4 is provided with a feeder 10 at the rear of the magazine 8 and the fastener is connected. By pushing 4 to the injection port 1 side, the top stopper 5 of the connecting stopper 4 is supplied into the injection port 1, and after the top stopper 5 is driven by the driving rod 7, the stoppers are sequentially installed from the rear side. Supply 15. In such a driving machine, even if the feeder 10 cannot press the connecting stopper 4 for some reason, the head stopper 5 is completely inserted into the injection port 1 due to the weight of the connecting stopper 4 itself or vibration during driving. When entering, a part of the stopper head 6 looks into the firing outlet 1 halfway.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional driving machine has the following problems. In the normal state, the leading end stop 5 is completely fed into the ejection opening 1, and the second stopper 14 next to the leading end stop 5 is pushed by the rear feeder 10, so that the leading end stop 5 moves backward (see FIG. 3). It is prevented from being hit in the direction of arrow D). However, if the feeder 10 is locked at the rear of the magazine 8 when the connecting stopper 4 is installed, it is possible to forget to push the connecting stopper 4 after removing the feeder 10 after mounting the connecting stopper 4, The feeder 10 has a bad operation due to clogging of foreign matters such as broken pieces of the connecting band 9 in the magazine 8, or the connecting stopper 4 having a bad dimension is loaded, and the feeder 10 from the rear side is damaged. When the front stopper 5 supplied to the injection port 1 is driven when the load becomes 0 or becomes significantly weak, the second stopper 14 next to the front stopper 5 is not pressed, so that the front stopper 5 moves backward. It is dangerous to be struck by. In particular, it is extremely dangerous to shoot out when the stopper head 6 is incompletely seen. The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and provide a safe driving tool.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the driving tool of the present invention is provided with an elastic restoring material in the stopper passage immediately before the ejection port or a stopper stopper capable of moving forward and backward in the stopper passage. The attachment position of the stopper stopper is the position immediately before the injection port, and the position where the second stopper next to the first stopper can be locked when the connecting stopper is normally loaded. It must be installed so that it does not come into contact with the driving rod. The position of the stopper in the axial direction is most effective at the stopper head, but the stopper shaft portion may be on the upper side of the entire length of the stopper. If it is on the lower side, the head of the stopper will look into the ejection port, and it will not be effective if it is hit by the driving rod.

[0005]

[Action]

 The stopper stopper configured as described above deforms with respect to the pushing load of the feeder or retracts from the stopper passage to supply the stopper into the injection port, and is connected when the pushing load of the feeder is 0 or extremely weak. The weight of the stopper is such that it cannot enter the injection port due to its own weight or vibration. Therefore, when the pushing load of the feeder becomes 0 or becomes extremely weak for the reason described above, it is possible to prevent the coupling stopper from entering the injection port. When the hammer is driven with the stopper stopper working, only the hammer will move, and the material to be hammered will have dents, but the damage will be minor.

【Example】

 The present invention will be described below with reference to the accompanying drawings. 3 is a partial sectional view of the driving tool, FIG. 1 is a sectional view taken along the line AA of FIG. 3 of the driving tool of the present invention, showing a state in which a stopper stopper is working, and FIG. 2 is shown in FIG. FIG. 6 is a view showing a state in which the stopper is normally sent to the ejection port. In FIG. 3, the feeder 10 is always pulled toward the ejection port 1 side (direction of arrow B) by the mainspring 17, and the feeder 10 is pulled rearward (direction of arrow C) to load the connecting stopper 4, The stopper 4 is pushed in the direction of arrow B from the rear by the feeder 10. When a driving operation is performed by a switch (not shown) in this state, the driving rod 7 is rapidly lowered, and the leading end stopper 5 in the injection port 1 is driven into the driven material 12. After the driving is completed, when the driving rod 7 is lifted up, the feeder 10 is pushing the coupling stopper 4 from the rear, so that the next stopper 14 is sequentially sent to the injection port 1 and the driving operation is repeated.

In FIG. 1, a stopper stopper 2 made of a rubber plate is attached to both sides of a stopper passage 3 by a mounting screw 17 on a nose 16 which forms an injection port 1 inside, and a load pushed by a feeder 10 is applied. It is a state in which the connecting stopper 4 that has passed through the stopper passage 3 in the state of 0 or extremely weak is prevented from entering the injection port 1 by the stopper stopper 2. If the driving operation is carried out in this state, the driving rod 7 moves up and down the driving rod passage locus 11 shown by the chain double-dashed line, and the head stopper 5 is not driven.

FIG. 2 shows a state in which the connecting stopper 4 is normally pushed by the feeder 10, overcomes the load of the stopper stopper 2, and the leading stopper 4 is fed into the injection port 1. If the driving operation is performed in this state, the driving rod 7 passes through the driving rod passage locus 11 shown by the chain double-dashed line, so that the head stopper 5 is normally driven.

In the above embodiment, the stopper stopper 2 is made of rubber, but it may be made of steel leaf spring. Alternatively, a member that is biased toward the stopper passage 3 by a coil spring or the like may be capable of moving forward and backward with respect to the stopper passage 3. The point is that it can move forward and backward with respect to the stopper passage 3 with a light load, and the load for locking the connecting stopper 4 may be set as described in the section of the above action.

[0010]

[Effect of device]

 According to the present invention, an elastic restoration member or a stopper stopper capable of advancing and retracting in the stopper passage is provided in the stopper passage just before the injection port, so that the connecting stopper is pressed when the pushing load of the feeder is 0 or significantly weak. Will not enter the injection port, and safety can be improved.
