[0029] One side of the movable screw block 15 is snapped into the inside of the first embedding groove 14, and one side of the movable screw block 15 is fixedly connected to an elastic card 17. One side of the elastic card 17 is snapped into the inside of the second embedding groove 16. Through the installation and use of the movable screw block 15 and the elastic card 17, they can be positioned inside the first embedding groove 14 and the second embedding groove 16 respectively, for limiting and fixing the insulating pull rod and the connecting rod 2, and ensuring the stability of the insulating pull rod during assembly.

[0030] The outer surface of the insulating pull rod body 1 is fitted with a silicone sleeve 18 that is compatible with the umbrella skirt 3. Two symmetrically arranged elastic retaining rings 19 are snapped onto the outer surface of the silicone sleeve 18. The two elastic retaining rings 19 can be elastically snapped onto the silicone sleeve 18 for fitting and positioning the silicone sleeve 18.

[0033] The working principle of the insulating pull rod provided by this utility model is as follows:

[0034] By pulling the side plate 10 in sequence, the side plate 10 can compress the elastic positioning round seat 7. Then, the first bolt 11 is screwed in so that the first bolt 11 is threaded into the internal thread groove 13 of the bottom plate 12 to limit and fix the four positioning round seats 7. Next, the connecting rod 2 is snapped into the inside of the insulating pull rod body 1. Then, the first bolt 11 is screwed in the opposite direction to release the limitation on the side plate 10. In this way, the elastic positioning round seat 7 can extend itself and snap into the inside of the round groove 8 to lock the connecting rod 2. Then, the first bolt 11 is screwed in so that the first bolt 11 is screwed into the inside of the internal thread groove 13 to securely lock the position of the connecting rod 2. Then, the movable rotating block 15 is rotated in sequence so that the movable rotating block 15 is snapped into the inside of the first embedding groove 14. At the same time, the movable rotating block 15 will also drive the elastic card 17 to snap into the inside of the second embedding groove 16, which is conducive to the stable assembly of the insulating pull rod body 1 and the connecting rod 2, improving the stability of the insulating pull rod during assembly and use, and making it less prone to loosening.

[0035] By attaching the silicone sleeve 18 with one side opening to the umbrella skirt 3 of the insulating rod body 1, and then attaching two elastic retaining rings 19 to the silicone sleeve 18, and then tightening the second bolt 20 to fix the elastic retaining rings 19, and then threading the nut 21 onto the second bolt 20, the two elastic retaining rings 19 can be used to position the silicone sleeve 18. Then, the rotating plate 23 can be used to rotate and adjust the semicircular rings 22 and 24 to fit them to the middle position of the outer surface of the silicone sleeve 18. Rotate the rotating plate 27 to the inside of the second support plate 26, and then tighten the third bolt 28 to fix the third bolt 28 into the rotating plate 27, so that the two semicircular rings can further position the silicone sleeve 18. In this way, the silicone sleeve 18 can wrap the umbrella skirt 3, which helps to improve the insulation effect and extend the service life of the insulating rod.
