, and a screw hole 19 is bored on the side of the leg 9.
It is rotatably but non-removably attached by a screw N screwed into the shaft support 13 of the main body cylinder 3 from the crowned circular portion 7. The shielding wall 23 of the main body 1 and the shielding wall 28 of the oscillating body 5 form a straight line so as to intersect both plates 2 and 6 when the main body seat plate 2 and the oscillating body substrate 6 are parallel to each other.
The main body limiting portion 4 and the rocking body limiting portion 8 can swing within a range until they come into contact with each other, specifically within a range of 0 to 130 degrees.

Since the proposed connector has the above-mentioned structure, the main body 1 and the swinging body 5 are molded separately in advance, and the space A _{2 is provided in which the cylinder 3 of the main body 1 is provided above the cylinder 7 of the swinging body 5.} In addition, the celestial circle portion 7 of the rocking body 5 is inserted into the space _A1 provided at the bottom of the celestial cylinder 3 of the main body 1, and the celestial cylinder 3 of the main body 1 and the celestial circle of the rocking body 5 are inserted.

After locking to P ₁ , screw the screw S toward the column P through the insertion hole 22 of the fixed wall 12 provided at the bottom of the seat plate 2, or connect it to the insertion hole 22 in the side wall P ₁ of the column P. A screw hole h is provided, and a screw S is screwed into the screw hole h from the insertion hole 22 to firmly attach and fix the main body 1 to the support P. Next, the leg part 9 provided on the rocking body 5 is inserted into the hollow part b from one end of the horizontal bar B, and the screw S is screwed into the threaded hole 19 of the leg part 9 from the outside of the horizontal bar B. Attach and fix it to horizontal beam B. Conversely, it is also possible to first fix the rocking body 5 of the connector I to the horizontal beam B, and then fix the main body 1 of the connector I to the support P later.

It should be noted that the proposed connector is not limited to the above structure, but before assembling the main body 1 and the rocking body 5, these are attached to the support P and the horizontal beam B, and specifically, the main body 1
is fixed to the support P alone, and the swinging body 5 is fixed to the horizontal crosspiece B. Then, the fixed cylinder 3 of the main body 1 fixed to the support P and the closed circle of the rocking body 5 fixed to the horizontal crosspiece B are The parts 7 are fitted to each other so as to overlap vertically, and a screw N is screwed into the shaft support 13 of the cylinder 3 with a cylinder 3 from below the cylinder 7 with a cylinder 7, so that the main body 1 and the rocking body 5 can be rotated. Alternatively, the shaft support 13 and the shielding wall 23 provided on the upper part of the sky cylinder 3 of the main body 1, and the shielding wall 28 provided on the upper end of the rocking body 5 may be omitted depending on the cross-sectional shape of the horizontal bar B. However, the same purpose can be achieved even if the pivot support 13 is provided inside the celestial cylinder 3. Also, the procedure for connecting the main body 1 and the rocking body 5, and the connecting tool I for the support P and the horizontal beam B.
The mounting procedure, the shape and structure of the main body 1 and the rocking body 5, etc. can be changed as appropriate as long as they do not go against the gist of this invention.

[Effect of idea]

Therefore, the proposed connector is fixed by inserting and locking the claws provided on the back of the seat plate of the main body into the through holes of the pillars, and fixing the fixing wall at the bottom of the main body to the pillars with screws. Not only can it be fixed easily and strongly by screwing at certain points, but the appearance of the mounting part also improves because there are no fixing screws on the top of the mounting part, which is easily visible from the outside. In addition, since the proposed connector is rotatably connected by screwing a screw into the shaft support of the main body cylinder from below the rocking body part, the proposed connector can be used to connect handrails on balconies and rooftops that are exposed to wind and rain. Even if configured, water and dust will not accumulate on the main body and the pivot of the oscillating body, and there will be no rust or damage. Furthermore, the proposed connector can be rotated within a certain range, so when attaching the main body to the support, the swinging body can be rotated in one direction to facilitate the installation of the main body, or the swinging body can be attached to the horizontal beam. When installing, you can not only rotate the main body in one direction to make it easier to install the rocking body, but also
In addition to the above-mentioned features that make it easy to assemble the handrail, the connector of the present invention, such as being able to attach the horizontal beam to the support at an appropriate angle, has a beneficial effect on the long-term use of the handrail.
