[0026] The working principle of the above technical solution is as follows:

[0027] During use, the connection positioning mechanism 6 can be quickly adjusted so that the connection positioning mechanism 6 is disengaged from the fixed positioning groove 7, so that the fixed installation rod 1 and the movable connection sleeve 5 can move relative to each other to adjust the overall length. After the adjustment is completed, the connection positioning mechanism 6 and the fixed positioning groove 7 cooperate with each other to connect and fix the fixed installation rod 1 and the movable connection sleeve 5, and the operation is convenient and quick.

[0028] In another embodiment, Figure 1 As shown, a distance detection mechanism 8 is provided at the bottom of the fixed installation rod 1 .

[0029] After the distance detection mechanism 8 is connected between the whole body and the cable, the distance from the ground can be detected, and the operation is convenient.

[0030] In another embodiment, Figure 3 As shown, the connecting and positioning mechanism 6 includes a connecting sleeve block 9, and a movable positioning rod 10 is movably connected inside the connecting sleeve block 9. A force-bearing ring 11 is fixedly sleeved on the outer surface of the movable positioning rod 10. A force-bearing spring 12 is fixedly connected between one side of the force-bearing ring 11 and one end inside the connecting sleeve block 9. A connecting pull ring 13 is fixedly connected to the end of the movable positioning rod 10 away from the fixed installation rod 1.

[0031] It is convenient to pull the connecting pull ring 13 to drive the movable positioning rod 10 and the force-bearing ring 11 to move, thereby compressing the force-bearing spring 12, thereby quickly adjusting and operating conveniently.

[0032] In another embodiment, Figure 1 As shown, the inner side of the movable connecting sleeve 5 and the outer side of the surface of the fixed installation rod 1 are slidably fitted with each other.

[0033] The movable connection sleeve 5 can slide outside the surface of the fixed installation rod 1, which is convenient for operation.
