Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a tool for fixing pipes and rods in the rotating direction.

``Prior Art'' Conventionally, a pipe wrench was used that had a pipe side clamping groove perpendicular to the direction of the lever at the tip of the lever, and was used to fix the rotational direction of an upright boring rod when the rod was connected. used. However, with a pipe wrench, the upright pipe is held in the clamping groove, the lever is gripped, and the pipe is supported in the opposite direction to the direction in which the pipe rotates, thereby stopping the pipe from rotating. This is with the pipe attached and detached. Therefore, in order to fix the pipe, that is, to prevent the pipe from rotating, it was necessary to strongly hold the lever of the pipe wrench by hand to support the wrench, and human power was required to fix the lower pipe and rotate the upper pipe at the same time. When the lever of the pipe wrench is removed from your hand, the gripping groove will tilt as shown in Figure 6.
It was difficult to support the pipe wrench.

``Problems to be solved by the invention'' The purpose of this invention is to obtain a pipe fixing device that can fix a pipe in the direction of rotation without requiring human power.

"Means for solving the problem" The present invention is a tool in which a pipe side clamping groove is provided at the tip of the lever, which is perpendicular to the direction of the lever.
It is constituted by a pipe fixing device which is provided at the opening of the clamping groove with a pipe side abutment which can be opened and closed to close the opening.

``Operation'' Therefore, the pipe side fitting is opened and the vertical pipe side holding groove is turned horizontally to hold the upright pipe, the opening of the groove is closed with the above-mentioned fitting, and the same fitting is applied to the side of the upright pipe. Let them come into contact with you. In this state, even if the pipe side clamping groove tries to tilt toward the bottom due to the weight of the bottom of the groove, the tool prevents this and the groove is held horizontally. Therefore, a stopper such as a stake is brought into contact with one side of the lever to prevent the lever from rotating, and in this state, another pipe is screwed onto the upper end of the pipe, and the rotational force from the screwing is applied to the vertical pipe at the bottom. Even if the pipe is added, it is supported without rotating by the clamping groove held horizontally and in the rotational direction, and another pipe can be connected to the upper end by the threaded engagement.

Embodiment As shown in FIGS. 1 to 4, a pipe side clamping groove 2 is provided at the tip of the lever 1, which is perpendicular to the longitudinal direction of the lever 1. In this clamping groove 2, the base of a curved tip fitting 5 is rotatably connected to the tip of the lever 1 with a pin 6, and a small curved fitting 7 is pivoted to the tip of the metal fitting 5 with a pin 8 so that it can be opened and closed. It is what it is. The outer surface of the tip of the slightly curved metal fitting 7 can be pressed by the tip surface 1' of the lever 1 to clamp the upright pipe 9 between the two metal fittings 5 and 7. Then, with the small curved metal fitting 7, both metal fittings 5 and 7
The opening 3 of the clamping groove 2 can be closed and the pipe side abutment 4 can be formed by the small curved metal fitting 7. The lever and the curved end fitting 5 are pulled together by a spring 10, and one end of the spring 10 is connected to a mounting ring 11 of the metal fitting 5. And reciprocating rotation piece 1 to lever 1
2 is pivotally supported by a small pin 13 parallel to the pin 6, and stoppers 1 are provided at both ends of the same piece 12 in contact with the side surfaces of the lever 1.
2', 12', an arm 14 facing the base end of the lever 1 is provided in the center of the piece 12, the other end of the spring 10 is connected to a mounting ring 15 provided on the arm 14, and a small pin is attached. By rotating the same arm 14 around 13 to the imaginary line position in FIG.
By pressing the outer surface of the tip with the tip surface 1' of the lever 1, the side surface of the pipe 9 can be held. Same arm again 1
4 around the small pin 13 to the solid line position in FIG. 1, the metal fitting 5 can be turned around the pin 6 as shown in FIG. (The state is shown in Fig. 2). Fig. 4 shows that the upright pipe 9 is clamped and the lever 1 is tightened with the stopper stake 16.
The figure shows a state in which the rotation of the pipe 9 is stopped and another pipe 9' is screwed onto the upper end of the same pipe 9 using a pipe wrench 17. Further, as shown in FIG. 5, a pipe side fitting 4 for closing the opening 3 of the pipe side clamping groove 2 of the conventional pipe wrench 17 is formed with a tightening band 18 to fix the pipe of the present invention. It can be used as a tool. In the figure, 19 is a detour ring of the tightening band 18, 20 is a mounting ring of the band 18, and 21 is a sliding ring.

``Effect'' This project is configured as described above, so the vertical pipe 9
By simply clamping the lever 1 in the clamping groove 2, closing its opening, and stopping the rotation of the lever 1 with a stopper stake 16, etc., it is possible to stop the rotation of the vertical pipe 9 when the pipes are screwed together, and the effort required to do so is also saved. Connection or separation of boring rods, etc. can be performed by one person without any need.
