An annular filling block 21 is fixedly installed on one side of the second connector 4, a connecting pipe 22 is fixedly installed on one end of the annular filling block 21, a clamping groove 24 is provided on the side wall of the connecting pipe 22, an inner groove 9 is provided on the inner side of the hollow groove 7, a through groove 8 is provided on the outer side of the hollow groove 7, a spring 10 is fixedly installed on the inner cavity of the inner groove 9, a wedge block 11 is fixedly installed on one end of the spring 10, one end of the wedge block 11 is slidably connected to the inner cavity of the through groove 8, and a clamping groove 24 is provided on the side wall of the connecting pipe 22.
[0023] In this embodiment, when connecting the first joint 3 and the second joint 4, the connecting pipe 22 is inserted into the inner cavity of the hollow groove 7 through the annular groove 5. The wedge-shaped setting of the wedge block 11 makes it convenient for the connecting pipe 22 to press the wedge block 11 into the interior of the inner groove 9 when inserting the inner cavity of the hollow groove 7, thereby facilitating the connection between the connecting pipe 22 and the hollow groove 7.

The internal thread 18 and the external thread 19 are threadedly connected by rotating the annular sleeve 17, and the connection between the first joint 3 and the second joint 4 is fixed in and out, and the connection between the first joint 3 and the second joint 4 is hidden in the inner cavity of the annular sleeve 17 to prevent the connection between the first joint 3 and the second joint 4 from being corroded, thereby improving the fixing effect. The slider 15 slides in the inner cavity of the slide groove 14 to facilitate the limiting of the annular sleeve 17 so that the annular sleeve 17 is kept on the outside of the second joint 4, and the movement of the annular sleeve 17 is facilitated. The annular sleeve 17 and the slider 15 are connected by the setting of the connecting ring 16, and the movement of the annular sleeve 17 is facilitated. The connection between the annular filling block 21 and the annular groove 5 is sealed by the setting of the sealant 23 to prevent leakage. The annular sleeve 17 is conveniently rotated by the setting of the anti-slip strip 20.

The wedge-shaped setting of the wedge block 11 facilitates the connecting pipe 22 to be inserted into the inner cavity of the hollow groove 7, and the wedge block 11 is pressed into the interior of the inner groove 9, thereby facilitating the connection between the connecting pipe 22 and the hollow groove 7. The spring 10 pushes the wedge block 11 into the inner cavity of the card slot 24 to fix the first joint 3 and the second joint 4. When the subsequent bolts are fixed, the positions of the first joint 3 and the second joint 4 will not be offset, which is convenient for the subsequent fixing of the bolts. One person can complete it, saving labor and improving the connection efficiency. After the joint 3 and the second joint 4 are connected, the bolt 13 is threadedly connected to the inner cavity of the internal thread groove 12 to fix the first joint 3 and the connecting pipe 22 to fix the first joint 3 and the second joint 4.
