Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anchor driving device used for driving an anchor into a high place such as a ceiling.

[0002]

[Prior art]

 In the conventional anchor driving work, a tool is provided in which a driving anchor is attached to the tip of the anchor driving tool and the base end of the anchor driving tool is directly hit with a hammer and driven into a hole such as a wall or ceiling. It was In addition, Japanese Patent Application No. 4-2368 proposed by the present inventor has been proposed.

[0003]

[Problems to be solved by the device]

 Since the anchor driving tool and the hammer are different from each other in the above-mentioned conventional driving operation, it is common to injure by hitting a finger during the driving operation, and after setting the anchor on the tool, the hammer is used. Since it was necessary to change hands and hit the ball, the work was extremely complicated, and the anchor driving tool and the hammer had to be always carried as a set. In addition, when performing a striking work in a difficult work posture such as an upward work, the work efficiency was poor due to heavy finger striking and tired work. Further, the one proposed by the inventor of the present invention is not suitable for driving a large number of anchors because the hammer body is heavy when trying to increase the impact force of anchor driving, and the small turning is not effective in working. .

Therefore, the present invention solves the above-mentioned drawbacks, does not cause injury by hitting a finger, can easily and quickly work in difficult work places, and does not need to replace it with a hammer. It is an object of the present invention to provide an anchor driving device that can be driven easily and easily, is relatively light and has a small turning effect.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned drawbacks, a sliding part is installed on the upper side of the pipe-shaped sliding driving body, a compression spring and a spring stopper are also installed, and a driving anchor is held from the tip of the rod-shaped body. An anchor holding head and a striking portion having a diameter larger than that of the rod-shaped body are formed, and a guide portion is formed on the base end side of the rod-shaped body, and the guide portion is slid so as to be elastically urged by the compression spring. It is formed by fitting it into the sliding part of the dynamic driving body.

[0006]

[Action]

 Since it is configured as described above, when driving the driving anchor, the anchor part is inserted into the driving hole while the anchor is attached to the anchor holding head, and the pipe-shaped sliding driving is performed in that state. The main body is moved up and down so that the striking portion of the rod-shaped main body strikes the upper end of the sliding driving body, and the impact drives the anchor. When the sliding driving body is moved up and down, the rod-shaped body is always elastically urged upward by the compression spring of the sliding portion of the sliding driving body.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 is a sliding driving body, and the sliding driving body 1 is pipe-shaped and is set so that it can be added to the base end side depending on the height such as the ceiling in the length and slides to the upper end side. A portion 2 is formed, and as shown in FIG. 2, a guide stopper 3 is provided so as to slightly project inward from the outer periphery of a required portion of the sliding portion 2, and a spring 4 and a spring stopper 5 are provided in the inner portion. .

Further, the rod-shaped body 6 has an anchor holding head 8 for holding the anchor 7 at the upper end of the tip thereof, and an impact portion 9 having a diameter larger than that of the rod-shaped body 6 is formed on the lower side of the anchor holding head 8. While being formed, the lower side thereof is formed as a guide portion 10, and a sliding groove portion 11 having a required length is formed in the guide portion 10 in the longitudinal direction. Then, the guide portion 10 is fitted into the sliding portion 2 of the sliding driving body 1, and at that time, the tip portion of the guide stopper 3 is engaged with the sliding groove portion 11 of the guide portion 10, and The sliding groove 11 slides along the tip of the guide stopper 3. Further, the spring 4 elastically urges the guide portion 10 of the rod-shaped main body 6 so that the rod-shaped main body 6 always protrudes from the sliding driving body 1, and the tip end of the guide stopper 3 and the base end portion of the sliding groove portion 11. Is locked.

In the anchor holding head 8 shown in FIG. 3, a spring 13 elastically urges the anchor 7 so that the ball 12 slightly projects to the side of the anchor holding head 8 so that the anchor 7 can be easily removed. A holding body 14 is provided to hold it so that it does not exist.

When the anchor 7 is driven into the ceiling concrete 15 by the anchor driving device as shown in FIG. 4, first, the anchor 7 is held on the anchor holding head 8 and then the concrete 15 on the ceiling. The anchor 7 is fitted into the hole 16 formed in the hole, the sliding driving body 1 is moved up and down in this state, and the tip 17 of the sliding driving body 1 is hit against the hitting portion 9 of the rod-shaped body 6. . Due to this impact, the anchor 7 is held and fixed in the hole 16 of the concrete 15.

From the above, in the driving, the sliding driving main body 1 is slid so as to be lifted from the bottom by hitting lightly with both hands to strike the striking portion 9. This striking work is performed from the ground surface using the sliding driving main body 1 which is long toward the ceiling surface. If the slidable driving body 1 is lightly grasped by both hands and the striking work is performed such that the sliding striking body 1 is hit against the striking portion 9 of the rod-shaped body 6, the impact is dispersed and the burden on the hand is reduced. , Furthermore, the impact received on the hand becomes smaller.

Although the spring 4 elastically urges the rod-shaped main body 6 and the sliding driving main body 1 shown in this embodiment to constantly repel, the elastic urging force does not depend on this embodiment. As long as the structure allows it, the design may be appropriately changed and used. Although not shown in the drawings, it is also preferable that the sliding driving main body 1 is used as a joint from the lower end of the sliding driving body 1 at a suitable time depending on the height of the concrete 15 on the ceiling.

[Effect of device]

 The present invention effectively achieves the intended purpose by the above-mentioned configuration and operation. In particular, the sliding portion is installed inside the pipe-shaped sliding driving body and the compression spring and the burner top are installed inside. An anchor holding head for holding a driving anchor and the like from the tip of the rod-shaped body and an impact portion having a diameter larger than that of the rod-shaped body are formed, and a guide portion is formed on the base end side of the rod-shaped body. Since the guide portion is formed so as to be elastically urged by the compression spring and is fitted into the sliding portion of the sliding driving body, there is no possibility of hitting a finger with a hammer to cause injury. Impacting work can be performed easily and quickly even in difficult work areas. In addition, even if the sliding driving body is relatively light, it is possible to increase the striking force by grasping with both hands and performing a striking work, and because the small turning is effective, it is simple, easy and efficient. It can be used for striking work, and thus has a great effect in practical use.
