The cable body 11 is sleeved in the connecting tube 1202 in the sealing cover 6. The cable body 11 can be limited and clamped by the connecting tube 1202 and the spring piece 1203. Then, the sleeve 1205 is sleeved on the outside of the connecting tube 1202 and tightened. During the tightening process, the spring piece 1203 and the internal cable body 11 are squeezed, thereby improving the sealing performance of the cable body 11.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the locking mechanism 2 includes a fixed cylinder 201, a telescopic rod 202, a slide plate 203, a slider 204, a slide groove 205, a spring 206, and a clamping column 207.

The sleeve 1205 is sleeved on the outside of the connecting tube 1202 and tightened. During the tightening process, the spring piece 1203 and the internal cable body 11 are squeezed, thereby improving the sealing of the cable body 11.

[0037] The working principle of the utility model is as follows: firstly, the cable body 11 is passed through the connecting tube 1202 and the sleeve 1205 on one side of the sealing cover 6, and the spring piece 1203 at one end of the connecting tube 1202 is used to limit and clamp the cable body 11, and then the sleeve 1205 is sleeved on the outside of the connecting tube 1202 and tightened. During the tightening process, the spring piece 1203 and the cable body 11 are squeezed internally, thereby improving the firmness and sealing of the cable body 11. When the cable body 11 is installed, the inner ring 9 inside the sealing cover 6 is inserted into the pre-buried pipe body 1 and the inner ring 9 inside the sealing cover 6. The sleeves 4 are movably connected with each other, and the setting of the first sealing ring 3 on one side of the embedded pipe main body 1 and the second sealing ring 10 outside the sealing cover 6 can improve the sealing performance of the connection between the sealing cover 6 and the embedded pipe main body 1.
