Description

Technical Field

[0001] This utility model relates to the field of electrical transmission technology, and in particular to an insulated saw with an adjustable drop angle. Background Technology

[0002] The transmission of electrical energy is a crucial component of the overall function of a power system. Power plants and load centers are typically located in different regions. By establishing power plants in areas with suitable primary energy resources such as hydropower and coal, electricity can be transmitted to load centers far from the power plants, allowing the development and utilization of electrical energy to transcend geographical limitations. Insulating saws play a vital role in the maintenance and repair of power systems. They are primarily used in scenarios requiring high-altitude operations, such as trimming tall vegetation within power facility protection zones. Due to their insulated design, they can be used while working on live lines, significantly improving work efficiency and safety. Therefore, an insulated saw with an adjustable drop angle is particularly needed.

[0003] The following problems exist with the use of insulated saws currently on the market:

[0004] Most existing insulated saws often suffer from inflexible angle adjustment when pruning branches, causing pruned branches to fall freely, potentially injuring operators or surrounding objects. This reduces the practicality and safety of the insulated saw. As a result, operators tend to grab the branches to prevent them from falling, but this not only increases the operator's workload but also increases the risk of hand injuries. Furthermore, some branches at higher elevations are difficult to hold onto, further diminishing the insulated saw's usability. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an insulated saw with an adjustable falling angle, including an extension rod 1, an installation mechanism 2 on the extension rod 1, and an adjustment mechanism 3 on the installation mechanism 2;

[0021] The mounting mechanism 2 includes a first connector 21, a base 22, a pressing block 23, a spring 24, a second connector 25, and a ball bearing 26. The first connector 21 is fixedly connected to the upper surface of the extension rod 1. The base 22 is fixedly connected to the upper surface of the first connector 21. The pressing block 23 is mounted on the upper surface of the base 22. The spring 24 is sleeved on the outer surface of the pressing block 23. The second connector 25 is mounted on the upper surface of the first connector 21. The ball bearing 26 is disposed inside the second connector 25. Through the arrangement of the first connector 21, base 22, pressing block 23, spring 24, second connector 25, and ball bearing 26, when it is necessary to adjust the first connector 21 and the second connector 25... When installing connector 25, firstly, the second connector 25 is snapped into the base 22. At this time, the pressing block 23 is compressed by the pressure of the second connector 25, and the spring 24 is compressed. When the second connector 25 is fully snapped into the first connector 21, the spring 24 drives the pressing block 23 to reset due to its own elasticity, so that the pressing block 23 is snapped into the interior of the second connector 25. At the same time, the ball bearing 26 inside the second connector 25 is snapped into the slot of the first connector 21, so as to achieve the effect of fixing the first connector 21 and the second connector 25 to each other, and increasing the stability of the connection between the first connector 21 and the second connector 25.

[0022] Furthermore, the adjustment mechanism 3 includes a fixed block 31, an electric saw 32, an adjustment plate 33, a fixed plate 34, and a motor 35. The fixed block 31 is mounted on the extension rod 1, the electric saw 32 is mounted on the fixed block 31, the adjustment plate 33 is mounted on the outer wall of the fixed block 31, and the fixed plate 34 is fixed to the outer wall of the fixed block 31. The motor 35 is mounted on the fixed plate 34. Through the arrangement of the fixed block 31, electric saw 32, adjustment plate 33, fixed plate 34, and motor 35, during use, the operator first starts the motor 35. The motor 35 drives the adjustment plate 33 to rotate, which in turn drives the fixed block 31 and the electric saw 32 to rotate together, thus realizing the sawing operation of the branches. Simultaneously, the operator can adjust the angle of the adjustment plate 33 to adjust the falling angle of the electric saw 32, thereby achieving precise control of the branch pruning angle. This ensures that the pruned branches fall in a predetermined direction, avoiding the safety hazards that may arise from branches falling randomly, ensuring that branches are cut as needed, and effectively improving the ease of operation and safety performance of the insulated saw.

[0023] Furthermore, a fixing hole 4 is provided on the outer wall of the extension rod 1, and a handle 5 is installed on the outer wall of the extension rod 1. With the setting of the fixing hole 4, the operator can use the connecting bolt 7 to pass through the fixing hole 4 to fix the handle 5 according to the actual use situation, so that the operator can better hold and operate the insulating saw, increasing the convenience and flexibility of using the insulating saw.

[0024] Furthermore, a fixing bolt 6 is provided on the outer wall of the handle 5. With the fixing bolt 6, the operator can use the fixing bolt 6 to fix the connecting buckle 7 to ensure that the handle 5 will not loosen or fall off during operation, which further improves the stability and safety of the insulated saw.

[0025] Furthermore, a connecting bolt 7 is provided on the outer wall of the handle 5. With the setting of the connecting bolt 7, the operator can insert the connecting bolt 7 into the fixing hole 4 according to actual needs, thereby fixing the position of the handle 5 to adapt to different operating requirements.

[0026] Working Principle: In use, the operator first grips the insulated saw with handle 5, then secures it by passing the connecting bolt 7 through the fixing hole 4, ensuring a better grip and operation. Next, the operator starts the motor 35, which drives the adjusting plate 33 to rotate. The adjusting plate 33 then rotates the fixing block 31 and the electric saw 32 together, initiating the sawing operation. During sawing, the operator can adjust the angle of the adjusting plate 33 to control the falling angle of the electric saw 32, precisely controlling the pruning angle and ensuring the pruned branches fall in the predetermined direction, effectively avoiding potential safety hazards from randomly falling branches. Simultaneously, the design of components such as the first connecting piece 21 and the second connecting piece 25 in the installation mechanism 2 ensures the stability and robustness of the entire insulated saw structure, improving its service life and safety performance. The entire operation is simple and convenient, greatly improving work efficiency and operational safety.
