[0041] The connector 11 is slidably connected to the first protection tube 1, and the first protection tube 1 includes a first tube body 12 and a first retaining ring 121 detachably connected to the end of the first tube body 12. The connector 11 is provided with a first ring body 111 that cooperates with the first retaining ring 121 to prevent the connector 11 from sliding out of the first tube body 12.

[0042] The adapter 21 is slidably connected to the second protection tube 2, and the second protection tube 2 includes a second tube body 22 and a second retaining ring 221 detachably connected to the end of the second tube body 22. The adapter 21 is provided with a second ring body 211 that cooperates with the second retaining ring 221 to prevent the adapter 21 from sliding out of the second tube body 22.

[0043] A portion of the connector 11 extends into the receiver 21, and the first retaining ring 121 and the second retaining ring 221 are both located in the connector 11;

[0044] The portion of the connector 11 extending into the receiver 21 is provided with a spring pin 3 , and the receiver 21 is provided with a pin hole 212 matched with the spring pin 3 . The spring pin 3 is arranged along the diameter direction of the first tube body 12 .

[0045] During the assembly process, the connector 11 is first sleeved on the first tube body 12, and then the first retaining ring 121 is installed on the first tube body 12. The adapter 21 is sleeved on the second tube body 22, and then the second retaining ring 221 is assembled with the second tube body 22.

[0046] The connector 11 is slid along the axial direction of the first tube body 12 so that a portion of the connector 11 extends into the receiver 21. When the spring pin 3 is aligned with the pin hole 212, a portion of the spring pin 3 enters the pin hole 212. At this time, the connector 11 and the receiver 21 are matched, and the splicing of the first tube body 12 and the second tube body 22 is completed.

[0047] In some embodiments, there are at least two spring pins 3 , and the at least two spring pins 3 are evenly distributed along the circumferential direction of the first tube body 12 , and each spring pin 3 corresponds to an independent pin hole 212 .

[0051] The number of spring pins 3 is not limited and can be reasonably determined as needed. The side of the cable protection tube that contacts the ground may not be provided with spring pins 3 to prevent the downward spring pins 3 from being difficult to operate.

[0054] The guide surface 213 is tilted so that the force applied by the guide surface 213 to the spherical head is divided into two components, one of which is parallel to the axis of the pin body 31, thereby overcoming the elastic force of the elastic member 32 and allowing the pin body 31 to enter the mounting hole to prevent interference between the pin body 31 and the socket 21 during assembly of the connector 11 and the socket 21.

[0055] In some embodiments, the first retaining ring 121 is fixed to the first tube body 12 by screws, and the second retaining ring 221 is fixed to the second ring body 211 by screws.
