It can be understood that the above-mentioned solution can be used in the scene of closing the opening on the elbow body 102, and can also be used to solve the problem of unstable movement of the two threaded sleeves 117.

[0022] According to this specific embodiment, the elbow body 102 is arranged on one side of the fastener body 101, the mounting shell 104 is arranged on one side of the fastener body 101, the rotating member 105 is arranged on the mounting shell 104, the two connecting plates 106 are respectively arranged on one side of the rotating member 105, the two fixed heads 107 are respectively fixedly connected to the two connecting plates 106, and are respectively located on one side of the two connecting plates 106, and the closing rod 108 is rotatably connected to the elbow body 102, and is located on the side of the elbow body 102 away from the fastener body 101. The fastener body 101 provides installation conditions for the elbow body 102 and the closing mechanism 103. The fastener can be externally fixed through the fastener body 101 and the elbow body 102. The closing rod 108 has two fixing holes. The mounting shell 104 provides installation conditions for the rotating member 105 and the two connecting plates 106. Rotating the rotating member 105 can drive the two connecting plates 106 to move closer to or away from each other. The movement of the two connecting plates 106 can drive the two fixed heads 107 to move closer to or away from each other. The two fixed heads 107 cooperate with the closing rod 108 to close the opening of the elbow body 102.

[0023] The disc 115 is rotatably connected to the mounting shell 104 and is located on one side of the mounting shell 104.

Rotating the disc 115 can drive the bidirectional screw 116 to rotate, and the rotation of the bidirectional screw 116 can drive the two threaded sleeves 117 to move closer to or farther away from each other. The movement of the two threaded sleeves 117 can drive the two connecting plates 106 to move closer to or farther away from each other.

[0024] Secondly, the slide rail 109 is fixedly connected to the mounting shell 104 and is located on one side of the mounting shell 104. The two sliders 110 are respectively fixedly connected to the two threaded sleeves 117 and are respectively slidably connected to the slide rail 109. The slide rail 109 provides installation conditions for the two sliders 110. When the two threaded sleeves 117 move, the two sliders 110 can be driven to slide on the slide rail 109.
