[0002] With the rapid development of power transmission and transformation in China, the construction technology has become more and more standardized, scientific and technical, and the equipment used has also become more and more advanced. In recent years, the phenomenon that tall plants near overhead power lines endanger the safety of power lines has become increasingly serious. In summer and autumn, tall trees along the power lines are frequently affected by thunderstorms, strong winds, typhoons and tornadoes, resulting in frequent incidents such as broken branches touching the lines or tree trunks falling and pressing on the lines, which in turn lead to frequent power outages due to power line tripping, seriously affecting the safe production of enterprises and the normal life of residents. Currently, when cleaning tall plants near overhead power lines, the operation is mainly carried out by a high branch saw after power outage, which requires a large amount of manpower and material resources, and the outage operation of the main lines will bring direct economic losses.

[0003] When the existing high branch saw needs to perform multi-directional cutting work, it is unable to adjust the angle of the saw body itself. This makes it impossible for users to flexibly adjust the angle of the saw body to adapt to different cutting directions and positions during actual operation, resulting in inconvenient use and low efficiency. Especially when dealing with branches at higher or farther positions, the fixed angle not only increases the operation difficulty but also may affect the cutting accuracy and safety. Content of the Utility Model

The outer wall of the extension rod two is fixedly connected with a worm gear, and inside the rotating sleeve, a worm is rotatably connected, which meshes with the worm gear. One end of the worm is fixedly connected with a knob two.

[0006] Further, the fixing component includes a fixing bolt, the outer wall of the fixing bolt is threadedly connected to the inside of the cross shaft, and a first knob is fixedly connected to the outer wall of the fixing bolt.

[0007] Further, a shoulder strap hanging ring is fixedly connected to the outer wall of the insulating rod, and a connecting sleeve is slidably connected to the outer wall of the insulating rod.

[0008] Further, a limiting screw is threadedly connected to the inside of the connecting sleeve, and the outer wall of the limiting screw is threadedly connected to the inside of the insulating rod.

[0009] Further, a T-shaped locking screw is threadedly connected to the inside of the connecting sleeve, and the outer wall of the T-shaped locking screw is threadedly connected to the inside of the insulating rod.

[0010] Further, a fastening sleeve is slidably connected to the outer wall of the second extension rod, and a fastening lock is slidably connected to the outer wall of the second extension rod.

Specific implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-3, an embodiment provided by the present utility model: a multi-angle electric insulated high-branch saw, including a rear handle 1, inside which there is a safety lock knob 2, a switch trigger 3, a speed regulation button 4, an outer wall of the rear handle 1 is fixedly connected with a power socket 5, inside which there is a battery 6, an inside of the rear handle 1 is fixedly connected with an insulating rod 7, inside the insulating rod 7 there is a slidable connection with a first extension rod 12, an outer wall of the first extension rod 12 is fixedly connected with a rotating ring 8, inside the rotating ring 8 there is a rotatable connection with a cross shaft 9, inside the cross shaft 9 there is a fixing component for restricting and fixing the position of the rotating ring 8, an outer wall of the first extension rod 12 is fixedly connected with a rotating sleeve 13, inside the rotating sleeve 13 there is a slidable connection with a second extension rod 14, an outer wall of the second extension rod 14 is fixedly connected with a worm gear 15, inside the rotating sleeve 13 there is a rotatable connection with a worm 16 which meshes with the worm gear 15, and one end of the worm 16 is fixedly connected with a knob two 17; the fixing component includes a fixing bolt 10, an outer wall of the fixing bolt 10 is threadedly connected inside the cross shaft 9, and an outer wall of the fixing bolt 10 is fixedly connected with a knob one 11;

[0025] Specifically, when it is necessary to adjust the cutting angle of the high-branch saw, the two first extension rods 12 are fixed on the rotating ring 8 and adjusted by rotating around the outer wall of the cross shaft 9, so that the position of the rotating ring 8 can be fixed at the required angle through the knob one 11. The knob one 11 is screwed into the inside of the cross shaft 9 to apply pressure to ensure the stable fixation of the position of the first extension rod 12. Then, the knob two 17 cooperates with the worm 16 to drive the worm gear 15 to rotate. The rotation of the worm gear 15 enables the second extension rod 14 to rotate inside the rotating sleeve 13, thereby allowing for fine-tuning and precise adjustment of the angle of the second extension rod 14. This ensures that the cutting angle of the high-branch saw can be quickly and accurately adjusted according to specific requirements, thus enhancing the operation flexibility and adjustability of the high-branch saw. At the same time, it not only provides a simple angle adjustment function but also ensures the stability and reliability during long-term use, ensuring the cutting accuracy and safety.

[0026] Refer to Figure 1 , Figure 4 and Figure 5, a shoulder strap hanging ring 18 is fixedly connected to the outer wall of the insulating rod 7, and a connecting sleeve 19 is slidably connected to the outer wall of the insulating rod 7; a limit screw 20 is threadedly connected inside the connecting sleeve 19, and the outer wall of the limit screw 20 is threadedly connected inside the insulating rod 7; a T-shaped locking screw 21 is threadedly connected inside the connecting sleeve 19, and the outer wall of the T-shaped locking screw 21 is threadedly connected inside the insulating rod 7; a fastening sleeve 22 is slidably connected to the outer wall of the second extension rod 14, and a fastening lock 23 is slidably connected to the outer wall of the second extension rod 14; an installation sleeve 24 is fixedly connected to the outer wall of the second extension rod 14, a guide plate 25 is fixedly connected inside the installation sleeve 24, and a chain body 26 is rotatably connected to the outer wall of the guide plate 25; a sealing cover 27 is threadedly connected to the outer wall of the installation sleeve 24, and a chain tension regulator 28 is arranged inside the installation sleeve 24;

[0027] Specifically, when the need arises to extend the high branch saw as a whole, the connecting sleeve 19 is sleeved on the outer walls of the insulating rod 7 and the first extension rod 12 and fixed by rotating the limit screw 20 and the T-shaped locking screw 21, which ensures that the connecting sleeve 19 is firmly fixed in the required position, and the insulating rod 7 and the first extension rod 12 are installed. At the same time, the fastening sleeve 22 and the fastening lock 23 play a reinforcing role, ensuring a firm and reliable connection between the second extension rod 14 and the installation sleeve 24. This not only guarantees the stability of the overall structure but also enhances the durability and safety of the high branch saw during use. Additionally, the chain tension regulator 28 can adjust the tightness of the chain body 26, which ensures the stability and reliability of the chain during operation. By adjusting the chain tension, the operator can adjust the working efficiency and cutting quality of the high branch saw according to actual needs. Finally, the sealing cover 27 is opened and lubricant is injected into the installation sleeve 24 to effectively reduce the friction between the chain body 26 and the guide plate 25, further improving the operating efficiency and service life of the high branch saw. This not only extends the service life of the high branch saw but also reduces the frequency of maintenance and replacement of components, thus saving time and cost.

[0028] Working principle: When the angle of the pole saw needs to be adjusted, the swivel rings 8 are fixed to both sides of the extension rods 12, and both are rotated on the outer wall of the cross shaft 9, so that the extension rods 12 on both sides can be rotationally adjusted. Then, the first knob 11 is screwed into the interior of the cross shaft 9, so that the first knob 11 can push and press the position of the swivel ring 8, thereby fixing the position of the extension rod 12. Then, by rotating the second knob 17 and cooperating with the worm 16 to drive the worm wheel 15 to rotate, the worm wheel 15 can drive the extension rod 14 to rotate inside the rotating sleeve 13, and thus the angle of the extension rod 14 can be adjusted, so as to achieve the effect of adjusting the cutting angle of the pole saw, improve the adjustability of the pole saw, and facilitate the use of the pole saw. When the whole pole saw needs to be extended, the connecting sleeve 19 is sleeved on the outer walls of the insulating rod 7 and the extension rod 12, and then the limit screw 20 and the T-shaped locking screw 21 are rotated to fix the connecting sleeve 19, thereby installing and fixing the insulating rod 7 and the extension rod 12. At the same time, the fastening sleeve 22 and the fastening lock 23 can strengthen the connection between the extension rod 14 and the mounting sleeve 24, and the chain tension regulator 28 can adjust the tightness of the chain body 26. By opening the sealing cover 27, lubricant can be injected into the interior of the mounting sleeve 24, thereby reducing the friction between the chain body 26 and the guide plate 25, so as to achieve the effects of extending the whole pole saw and adjusting the chain tension, improve the practicability of the pole saw, and extend the service life.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
