Nipples are widely used, and for example, so-called nipples, which have threads on both ends of the pipe, are commonly used to connect the main body of an electric water heater or gas water heater, or a water tap and a pipe. To attach the nipple to one of the connecting objects, first manually screw the tip of one threaded part of the nipple into the threaded part of the connecting object, and then grasp the center part of the nipple with a wrench. The screws are then tightened, but installation takes a lot of time, and especially when assembling products on a conveyor line, it has a large impact on other processes, and the larger the diameter of the nipple, the more physical strength is required. There is a drawback that the number of operators is limited, and/(with an iburench, the tightening results differ depending on the operator, the quality is not stable, and furthermore, it is difficult to use in narrow spaces.

子部１５は第４図に示す如く螺子の螺旋方向等間隔る。Figures 1 to 4 show an example of installing a nipple in which both 11aK male screws are stacked one on top of the other on an electric water heater. It is an electric tool that has a rotary shaft 2 that can be rotated, and the skitch can be operated while holding the handle 3 with one hand. As shown in Fig. 4, this is a socket for a 4Fi nipple.The inside of the short cylindrical body is formed into a rectangular shape with a diameter smaller than that of the central round hole, and there are five insertion holes for the tip of the rotating shaft 2, and the inside of the other end is formed into a rectangular shape with a smaller diameter than the central round hole. It is formed into a round shape with a larger diameter than the other part, and serves as a threaded hole 6 for a nipple, which will be described later. The tip of the rotating shaft 2 is formed into a square column shape, and a pin hole 7 is provided in the fitting hole 5 of the socket 4, and a corresponding pin hole 7 is provided in the tip of the rotating shaft 2. One end of the socket 4 is removably attached to the rotating shaft 2 by fitting the rubber ring 10f) with a bottle insertion hole. Further, a screw portion 15 that can be screwed into one screw portion 13 of the nipple KF'i nipple 12 at the other end of the socket 40 is provided, and the screw portions 15 are equally spaced in the helical direction of the screw as shown in FIG.

９に依然として螺着された俵となる。The installation of the ridged nonitsuful is explained with reference to Fig. 1, in which the operation of attaching the nipple to the electric hot water 11 using a device is as follows.
First, slightly screw in the other threaded part 14 of the nipple mounting screw hole 2'OK nipple 12 of the electric water heater 19 by hand, and then attach the nipple to the threaded part 15 of the socket 4 using the guide hole 18 of the socket 4. 12, and when the rotating shaft 2 of the power tool 1 is rotated in the forward direction, the nipple screw 514Fi is completely screwed into the nipple mounting screw hole 20, and the nipple screw 13 and the socket 4 are tightened completely.
An incomplete thread engagement occurs with the thread of pH 15. After that, if the rotating shaft 2 is rotated in the opposite direction, the nipple 12 and the socket 4 will be screwed together due to the incomplete screwing, and the socket 4 will separate from the nipple 12, but the nipple 12ij electric water heater 1
9 will still be a bale screwed on.

大を図ることができる。The apparatus for installing the nipple of the present invention has a socket attached to a rotating shaft that can be rotated in forward and reverse directions by power, and the socket (Km!
An appropriate notch is provided in the threaded part KFi that can be threaded into the threaded part of the nipple, and a stop is provided at the back of the threaded part, so that the threaded engagement between the socket and the nipple is not complete. Due to the combination K of the forward and reverse rotation function of the rotating shaft, the nipple can be firmly tightened to the desired object, and the socket can be freely removed from the nipple during direct consultation, reducing installation time and improving work efficiency. However, even with particularly large diameter nipples, it is possible to tighten the screws without any trouble, and since the torque is set at a constant level, there is no slippage/stopping caused by the operator when tightening and fitting, and it can be used in narrow spaces. This makes it possible to expand the scope of use.
