Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1 - 3 , a telescopic insulating operating rod, including an insulating telescopic rod body 1, a telescopic inner rod 2 is movably installed on the upper surface of the insulating telescopic rod body 1, a fixing frame 3 is fixedly connected to the upper surface of the telescopic inner rod 2, an operating hook 4 is movably installed on the upper surface of the fixing frame 3, sliding plates 5 are fixedly connected to the left and right surfaces of the operating hook 4, a plurality of limiting grooves 6 are opened on the lower surface of the operating hook 4, sliding grooves 7 are opened on the left and right inner walls of the fixing frame 3, a pushing plate 8 is movably installed on the inner surface of the fixing frame 3, a limiting plate 9 is fixedly connected to the upper surface of the pushing plate 8, a pulling ring 10 is fixedly connected to the lower surface of the pushing plate 8, notch openings 11 are opened on the left and right inner walls of the fixing frame 3, and two springs 12 are fixedly connected to the lower surface of the pushing plate 8.

[0025] Specifically, through the cooperation between structures such as the insulating telescopic rod body 1, the telescopic inner rod 2, the fixing frame 3, the operating hook 4, the sliding plates 5, the limiting grooves 6, the sliding grooves 7, the pushing plate 8, the limiting plate 9, the pulling ring 10, the notch openings 11, and the springs 12, the operating hook 4 can be conveniently adjusted in extension length before use, which is convenient for use according to work requirements. Moreover, multiple support points are provided for the operating hook 4, and when exerting force on the operating hook 4, the stability of the operating hook 4 can be ensured.

[0026] In this implementation plan: the sliding plates 5 and the sliding grooves 7 are arranged in corresponding sliding settings, and the limiting plates 9 and the limiting grooves 6 are arranged in corresponding clamping settings.

[0027] Specifically, the operating hook 4 can move stably back and forth by the sliding plates 5 on both sides fitting the sliding grooves 7 on the fixing frame 3 to adjust the extension length.

[0028] In this implementation plan: the other ends of the two springs 12 are respectively fixedly connected to the lower inner walls of the corresponding notch openings 11, and the pushing plate 8 and the notch openings 11 are arranged in corresponding sliding settings.

[0029] Specifically, the pushing plate 8 is pushed by the elastic force of the two springs 12 against the upper inner wall of the notch opening 11, and the limiting plate 9 can be stably clamped in the limiting groove 6.

[0030] Working principle: When the insulating operating rod is needed, the extension length of the operating hook 4 on the fixing bracket 3 of the telescopic inner rod 2 can be adjusted. Pull the pull ring 10 to move the push plate 8 and the limiting plate 9 downward together. The push plate 8 squeezes the spring 12 through the notches 11 on both sides, separating the limiting plate 9 from the limiting groove 6 on the operating hook 4. Then, the operating hook 4 can be moved back and forth through the sliding plates 5 on both sides in cooperation with the sliding groove 7 on the fixing bracket 3 to adjust the extension length of the operating hook 4 with respect to the telescopic inner rod 2 for convenient use. Then, make the limiting groove 6 at the corresponding position perpendicular to the limiting plate 9, release the pull ring 10, and the push plate 8 is pushed upward to reset by the elastic force of the two springs 12. The push plate 8 pushes the limiting plate 9 to be clamped with the limiting groove 6, so that the operating hook 4 can be stably limited on the fixing bracket 3. The fixing bracket 3 stably supports the operating hook 4, and the insulating telescopic rod body 1 and the telescopic inner rod 2 can be used in cooperation with the operating hook 4 on the fixing bracket 3.

[0031] Embodiment 2

[0032] Please refer to Figure 1 , on the basis of Embodiment 1, the present utility model provides a technical solution:

[0033] In this embodiment: A first fixing plate 13 is fixedly connected to the outer surface of the insulating telescopic rod body 1. A connecting belt 14 is fixedly connected to the outer surface of the first fixing plate 13. The other end of the connecting belt 14 is fixedly connected to a clamping plate 15. A second fixing plate 16 is fixedly connected to the outer surface of the insulating telescopic rod body 1.

[0034] Specifically, through the cooperation among structures such as the first fixing plate 13, the connecting belt 14, the clamping plate 15, and the second fixing plate 16, the whole insulating operating rod can be conveniently taken when moving and is convenient to carry around. When working, the connecting belt 14 can be retracted without affecting the work.

[0035] In this implementation scheme: A slot hole corresponding to the connecting belt 14 is formed on the upper surface of the second fixing plate 16. The clamping plate 15 is correspondingly clamped with the slot hole.

[0036] Specifically, the connecting belt 14 can cooperate with the slot hole on the second fixing plate 16 for retracting work. By fitting the clamping plate 15 to the bottom of the second fixing plate 16, the connecting belt 14 can be prevented from detaching from the slot hole on the second fixing plate 16.

[0037] Working principle: After the insulating telescopic rod body 1 is used and needs to be retracted and moved, the connecting belt 14 can be supported by the first fixing plate 13, and then the connecting belt 14 is stretched. The connecting belt 14 slides through the slot holes on the second fixing plate 16, and the other end of the connecting belt 14 is clamped on the second fixing plate 16 by the clamping plate 15. In this way, the entire insulating telescopic rod body 1 can be supported by the connecting belt 14, which is convenient for taking and moving. When working subsequently, the clamping plate 15 can be pulled to retract the connecting belt 14 through the slot holes on the second fixing plate 16, so that the connecting belt 14 can be attached to the insulating telescopic rod body 1 to avoid affecting the work.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
