FIG. 6 (a) is a plan view showing an example of a pedestal (hereinafter, pedestal) 10 of the low tension outlet, and FIG. 6 (b).
Is a front view thereof. Currently, there is no suitable tool for attaching and detaching this pedestal 10, and in most cases, it is done with bare hands.

In this case, simply turn the pedestal with your fingertips, or, as shown in FIG. 7, attach the screws 11, 11, 11 for attaching the cap to the pedestal 10 so that its head is sufficiently above the floor surface. It is screwed halfway to the exit state, and the heads of the screws 11, 11, 11 are turned as clues.

FIG. 7 (a) is a plan view showing a state in which the screw 11 is attached to the pedestal 10 with its head sufficiently above the floor surface.
Figure (b) is a front view thereof.

On the other hand, it is often difficult to remove and install with bare hands due to aging after installation. In such a case, as shown in the plan view of FIG. 8, the driver 13 is obliquely applied to the peripheral portion of the pedestal 10, and the hammer 13 strikes the driver 13 to tighten or loosen it for attachment / detachment.

FIG. 8 shows the case of tightening by this method.

Also, as shown in FIG. 9, attach the cap 15 to the screws 11,11,11
The tip of the driver 13 is inserted between the cap 15 and the pedestal 10 in the state of being attached to the pedestal 10 with, and the handle of the driver 13 is used as a lever to tighten or loosen to attach or detach.

FIG. 9 shows the case of tightening by this method.

(Problems to be solved by the invention) A method of attaching and detaching the above-described conventional pedestal with bare hands is as follows.
When installing the pedestal, it is not possible to tighten it enough so that it often loosens later, and when it is desired to remove it, it is often too forceful to remove it.

In addition, the method of screwing the screw into the pedestal halfway as shown in FIG.
It is better than just tightening with bare hands, but it takes time and effort to attach and remove screws, resulting in poor work efficiency.

Further, as shown in FIG. 8, a method of hitting a driver with a peripheral edge of the pedestal and hitting it with a hammer can sufficiently tighten the pedestal, but the pedestal is scratched.

In addition, as shown in Fig. 9, the method of inserting the tip of the driver between the attached cap and the pedestal and turning it can be tightened sufficiently, but it has the drawback of damaging the indoor line or creating kinks. is there.

The purpose of the present invention is to eliminate these drawbacks, and when attaching and detaching the base, it can be tightened sufficiently and loosened easily, without damaging the base or the wire that penetrates the base, and a low tension outlet that is easy to operate. It is to provide a tool exclusively for mounting.
