  An object of the present invention is to provide a swing-out tubular body that can suppress the intrusion of sand or the like into the bottom plug while smoothly maintaining the expansion and contraction operation of each tubular body.

〔Constitution〕
A feature of the invention according to claim 1 is that an end surface of the bottom plug is formed with a through hole for a bottom plug communicating with the internal space of the bottom plug, and an inner space of the bottom plug is formed in the receiving device. A through-hole for a receiving device that communicates with the internal space of the proximal-side cylindrical body is formed, and the movable body for opening and closing that can close the through-hole for the bottom plug is freely moved in the internal space of the bottom plug The function and effect are as follows.

[Action]
Through the through hole, the inner space of the bottom plug and the inner space of the proximal cylindrical body can flow air to and from the outer space, so that each cylindrical body can be smoothly inserted and removed.
Moreover, since the movable body for opening and closing is stored in the interior space of the butt plug, even if the butt plug is grounded with the handle of the ball up and down, the movable body for opening and closing moves freely in the butt plug, Since the through hole is closed, it is possible to prevent sand and the like from entering.
On the other hand, when the swinging operation is performed by returning each cylindrical body to the horizontal posture, the opening / closing moving body moves away from the through hole, so that air is introduced from the through hole, the internal space of the bottom plug, etc. Will not be sealed.

〔effect〕
Therefore, it is possible to provide a bottom plug that is difficult for sand or the like to enter while being able to configure a swing-out cylindrical body that allows easy insertion and removal of each cylindrical body.

〔Constitution〕
The characteristic configuration of the invention according to claim 2 is the invention according to claim 1, wherein the opening / closing moving body is placed in an opening portion facing the internal space of the bottom plug through hole to penetrate the bottom plug penetration. The mounting seat that can close the hole is formed, and the operation and effect thereof are as follows.

[Function and effect]
When the butt plug is grounded with the swing-out cylindrical body in the vertical orientation, the opening / closing moving body moves in the internal space and is placed on the mounting seat. The opening / closing moving body mounted on the mounting seat blocks the bottom plug through hole and prevents sand and the like from entering.
Therefore, by forming the mounting seat, the opening / closing moving body can be easily positioned within the bottom plug, and the opening / closing moving body can be maintained in a closed state in a stable state.

〔Constitution〕
The characteristic configuration of the invention according to claim 3 resides in that the opening / closing moving body is a spherical body, and its operational effects are as follows.

[Function and effect]
Since the opening / closing moving body is a spherical body, it is easy to move in the internal space of the bottom plug, and it is easy to switch between a state where the bottom plug through hole is closed and a state where the bottom plug through hole is opened.
