Furthermore, when the scissors 7 is positioned above the screw 5, one side of the scissors 7 hits the support 3, but the other side of the scissors 7 does not hit the lower support 4, and the support 4
be in a higher position.

A storage groove 9 in which a pair of terminal plates 8 are housed is formed in the base 1, and a blade holder spring 10 consisting of a pair of blade holder spring plates 11 is formed at one end of the terminal plate 8. has been done. The other end side of the terminal plate 8 has a terminal portion 1 formed in a substantially U-shape.
2 is provided. A locking spring 14 is disposed within the terminal portion 12 to connect a conductor of an electric wire from the outside to the terminal portion 12 .

A notch 15 is formed at the end of the terminal portion 12, and a piece 16a of a release button 16 arranged symmetrically between both terminal portions 12 is inserted into the groove formed on the side surface of the base 1. 17
Insert the tip of the driver 18 into the button and drive the release button 16. The release button 16 is driven to press the locking spring 14 and release the contact with the conductor of the electric wire 13. As shown in FIG. 2, a lid 19 is fixed to the upper surface of the storage groove 9 of the base 1 with screws 20, and an insertion hole 21 through which the electric wire 13 is inserted is bored in the center of the lid 19. Furthermore, an insertion groove 22 is formed in an arc shape on the lower surface of the base 1, corresponding to a portion of the arc-shaped blade receiving spring 10.

Here, three insertion grooves 22 are formed concentrically, and in the other insertion grooves 22, as shown in FIG. It is used for mechanical holding by hooking and locking. Incidentally, the insertion groove 22 for mechanical holding may be formed according to the size of the electric appliance, and may be further increased if the electric appliance is a large-sized electric appliance.

As shown in FIGS. 4 and 5, a base 26 houses an electric appliance, in this embodiment a fan motor 25.
is formed into a cylindrical shape, and a lid 27 is attached to the bottom surface of the base 26. The fan motor 25 is fixed within the base 26 with screws 28, and the lid 27 has an intake port 29 formed therein. Three hook blades 23 are concentrically fixed to the upper surface of the base 26 by screws 30, and the tips of the hook blades 23 are formed into a substantially L shape. In addition, two hook blades 2
3 is a live part, and the remaining hook blades 23 are non-charged and are used for mechanical holding as described above, and can also be used as a ground electrode.

One screw 30 for fixing the hook blade 23 to the base 26 is tightened together with a terminal piece 31 and connected to a lead wire 25a of the fan motor 25. As shown in FIG.
3, first, as shown in FIG. 9, position the scissors 7 inside the base 26, and when the scissors 7 reaches the back of the ceiling 32, rotate the screw 5 to remove the scissors 7. is rotated outward as shown in FIG. and,
Tighten the screws 5 and lower the scissors 7 to attach the base 1.
The base 1 is fixed to the ceiling 32 by sandwiching the ceiling 32 between the flange portion 1a and the scissors 7.

Next, when attaching the base 26 to the base 1, the hook blade 23 is inserted into the insertion groove 22 of the base 1 and rotated, so that the tip of the hook blade 23 fits into the blade holder. Spring 1
0, and the hook blade 23 is electrically and mechanically connected and fixed. Note that the hook blade 23 is locked to a stepped portion of the base 1 or the like. In this embodiment, the fan motor 25 is used as the electrical appliance, but other lighting equipment such as a downlight, a ventilation fan, a speaker, an electric clock, etc. can also be used.

Effects of the Invention As described above, the present invention provides a base that is installed in a through hole drilled in a construction material using scissors using screws, and has a hole in the center that is large enough to fit your hand; It is equipped with a base that is removably attached to the lower surface and stores electrical equipment inside, and has a terminal section on one end to which electric wires from the outside are connected, and the other end has a circular arc shape consisting of a pair of blade-receiving spring plates. A plurality of terminal boards with blade receiving springs formed therein are placed inside the base, and an arcuate insertion groove is formed on the bottom surface of the base corresponding to the blade receiving spring, and the terminal board is inserted into the insertion groove and rotated. By doing so, both sides of the blade come in contact with the blade spring, electrically and mechanically connecting and fixing the base to the base.The hook protrudes from the top of the base, so the base can be constructed using scissors. By inserting the hook blade of the base into which the electric appliance is placed in the material and storing the electric appliance into the insertion groove of the base and rotating it, both sides of the hook blade come into contact with the blade receiving spring of the terminal board. It can be electrically and mechanically connected, so by having both sides of the hooking plug blade in contact with the blade receiving spring of the terminal board, high capacity is possible. The hole is large enough to fit your hand, allowing for reliable installation and inspection, and the base can be detached and attached to the base with just one touch, making it easy to replace electrical equipment regardless of the wires involved. This has the effect of making it possible.

[0018] Also, in claim 2, the scissor metal fitting is urged upward by a spring and is attached to the screw so as to be freely threadable, and struts of different heights are provided on both sides of the screw protruding from the upper surface of the base. The scissor metal fittings are biased with a spring to prevent the scissor metal fittings from idling, and the scissor metal fittings can be tightened in an accurate position without holding the scissor metal fittings by hand. For use,
Compared to the case where the top plate is integrally formed from the pillars, since the top plate is not required, it is easier to mold the base and manufacture the mold.
