The middle of the pull plate 26 is fixedly connected to a clamping rod 27. An L-shaped arc clamping block 24 is provided on the lower surface of the T-shaped rod 23, and an arc plug plate 25 is provided on the surface of the L-shaped arc clamping block 24. At the beginning, one side of the L-shaped seat 21 is fixedly connected to a third spring 291, and one end of the third spring 291 is fixedly connected to a side block 292. A limiting groove is provided inside the L-shaped seat 21, and the surface of the limiting block 29 is slidably connected to the inside of the limiting groove. A through hole is provided at one end of the limiting groove, and the surface of the round rod 28 passes through the through hole provided at one end of the limiting groove.

[0032] Furthermore, a clamping hole is provided on the surface of the T-shaped rod 23, and the surface of the clamping rod 27 matches the inside of the clamping hole. An L-shaped groove is provided inside the arc insert plate 25, and the surface of the L-shaped arc clamping block 24 is clamped with the inside of the L-shaped groove. A socket is provided on the top of the L-shaped arc clamping block 24, and the lower surface of the T-shaped rod 23 matches the inside of the socket. Pulling open the pull plate 26 drives the clamping rod 27 to disengage from the clamping hole on the T-shaped rod 23, and then drives the T-shaped rod 23 downward to be inserted into the socket inside the L-shaped arc clamping block 24, and allows the clamping rod 27 to be clamped into another clamping hole on the T-shaped rod 23, so that the lower connecting pipe 34 and the upper connecting pipe 1 can be reinforced and fixed again after installation, thereby improving the firmness of the upper connecting pipe 1 and the lower connecting pipe 34 after installation.

[0033] Example 2

[0034] See Figure 1-7The bottom end of the round seat 31 is fixedly connected to the top of the round seat 31, and the bottom end of the round seat 31 is fixedly connected to the top of the round seat 31. The bottom end of the round seat 31 is provided with a mounting seat 33, and the bottom end of the mounting seat 33 is fixedly connected to the lower connecting tube 34. The side of the round seat 31 is rotatably connected to a swivel 35, and the surface of the swivel 35 is fixedly connected to the dial ring 36. The surface of the arc plug plate 25 is fixedly connected to the inside of the mounting seat 33, and one side of the L-shaped arc block 24 is fixedly connected to the inside of the swivel 35. The bottom end of the L-shaped seat 21 is fixedly connected to the top of the round seat 31, and the bottom end of the side block 292 is fixedly connected to the top of the dial ring 36. An arc slot is provided inside the round seat 31, and the surface of the arc plug plate 25 is plugged into the inside of the arc slot. An L-shaped slot is provided on one side of the arc slot in the horizontal direction. The surface of the L-shaped arc block 24 matches the inside of the L-shaped slot, and one side of the L-shaped slot matches the inside of the arc slot.

[0035] Furthermore, a sealing groove is provided on the top of the mounting seat 33, and the surface of the sealing ring 32 fits tightly with the inside of the sealing groove. The mounting seat 33 and the arc plug plate 25 connected to the lower connecting pipe 34 are inserted into the inside of the round seat 31. Then, the shift ring 36 is loosened and the elastic action of the third spring 291 drives the L-shaped arc block 24 to be inserted into the card groove inside the arc plug plate 25. At this time, the sealing ring 32 fits tightly with the inside of the sealing groove on the mounting seat 33, thereby completing the preliminary limit installation operation of the connection between the lower connecting pipe 34 and the upper connecting pipe 1, and the installation is convenient, fast and easy to operate.

[0036] When the upper connecting tube 1 and the lower connecting tube 34 need to be installed, the shift ring 36 is first opened to drive the rotating ring 35 and the L-shaped arc block 24 to rotate counterclockwise. At this time, the mounting seat 33 connected to the lower connecting tube 34 and the arc plug plate 25 are inserted into the inside of the round seat 31. Then, the shift ring 36 is released and the elastic action of the third spring 291 drives the L-shaped arc block 24 to be inserted into the slot inside the arc plug plate 25. At this time, the sealing ring 32 is tightly fitted with the inside of the sealing groove on the mounting seat 33, thereby completing the preliminary limit installation operation of the connection between the lower connecting tube 34 and the upper connecting tube 1. The installation is convenient, fast and easy to operate.

[0037] When it is necessary to reinforce and fix the installed lower connecting pipe 34 and upper connecting pipe 1 again, the T-shaped rod 23 is located just above the socket at the top of the L-shaped arc block 24. At this time, the pull plate 26 is pulled open to drive the clamping rod 27 to disengage from the clamping hole on the T-shaped rod 23, and then the T-shaped rod 23 is driven downward to insert into the socket of the L-shaped arc block 24, and the clamping rod 27 is clamped into another clamping hole on the T-shaped rod 23, so that the lower connecting pipe 34 and the upper connecting pipe 1 can be reinforced and fixed again after installation, thereby improving the firmness of the upper connecting pipe 1 and the lower connecting pipe 34 after installation.
