[0025] The clamp 4 is fixedly connected to the outside of the pipe body 1 by bolts. Several screws 6 are fixed to one side of the clamp 4 and installed in a ring around it. By fixing the clamp 4 to a suitable position on the outside of the pipe body 1, the ends of the screws 6 extend out a certain length.

[0026] The sealing groove 8 matches one end of the pipe body 1. The interior of the sealing groove 8 is filled with a sealing ring. One end of the pipe body 1 is snapped into the sealing groove 8, and the sealing ring provides a seal.

[0027] The screw 6 corresponds to the groove 9. The screw 6 is inserted into the groove 9 and connected by a nut. The screw 6 is inserted into the groove 9 and the connecting sleeve 5 is fixed between the two pipe bodies 1 by the threaded connection of the nut.

[0028] Specifically, one end of the pipe body 1 is snapped into the sealing groove 8, while several screws 6 are inserted into the corresponding rod grooves 9. The clamp 4 is tightened and fixed by the threaded connection of the nut. Then, the clamp 4 at the other end of the connecting sleeve 5 is connected to another pipe body 1 to facilitate the fixing and sealing of the two pipe bodies 1.

[0029] Example 2

[0030] See Figure 3 Furthermore, based on Embodiment 1, the protective component 3 includes several telescopic tubes 10 and several protective cylinders 11.
