[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The present application provides an adjustable resistance live working pole, which is mainly used to solve the problem that when the live working pole is used to open and close the switch on the distribution line, the switch is generally set at a high position, and the operator needs to climb up the pole or tower to operate, which is troublesome and unsafe. In addition, the operator needs to hold the live working pole with his arms, which will cause a huge burden on the operator's arms. The following technical solutions are provided. Figure 1-Figure 8 Make a detailed description: The utility model discloses an adjustable resistance live working pole, which mainly comprises a supporting pole 1, an extension pole 2, a connecting head 3 and an operating head 4. A plurality of evenly distributed supporting legs 11 are arranged at one end of the supporting pole 1. The plurality of supporting legs 11 are umbrella-shaped, which can improve the stability of the device when placed on the ground. The number of the extension poles 2 is multiple and they can be spliced ​​according to the required length, so that the pole length can be flexibly adjusted in different working scenes. This design enables the adjustable resistance live working pole to adapt to the working requirements of different heights or depths, and improves the flexibility and applicability of use. The connecting head 3 is installed at one end of the extension pole 2, and the two extension poles 2 are connected by the connecting head 3 on one of the extension poles 2. The other end of the supporting pole 1 is installed with the connecting head 3, and the extension pole 2 is connected to the supporting pole 1 by the connecting head 3 on the supporting pole 1. The connection of the connecting head 3 can ensure the stability between the various components. A lifting rod 12 is movably inserted at one end of the supporting pole 1 facing away from the supporting leg 11, and a driving member 13 for controlling the movement of the lifting rod 12 is arranged on the supporting pole 1. The extension pole 2 comprises a mounting sleeve 21 and a mounting sleeve 22. The top of the lifting rod 12 pushes the lowest mounting rod 22 to rise, thereby raising the top mounting rod 22, and the operating head 4 opens and closes the switch. The device is set on the ground to open and close the switch on the transmission line, which is convenient to operate and has high safety. The height of the device can be changed according to different application scenarios, and the practicality is higher. It should be noted that in this scheme, the operating head 4 is used to realize the opening and closing of the switch. The specific shape of the operating head 4 is as follows: Figure 7 As shown, in other embodiments, different operations can be achieved by replacing different operating heads.

[0025] In this example, see Figure 2 , Figure 5 and Figure 6The driving member 13 includes a motor 131 arranged inside the support rod 1, and the output shaft of the motor 131 is arranged along the length direction of the support rod 1. A screw rod 132 arranged along the length direction of the support rod 1 is fixed on the output end of the motor 131, and the jacking rod 12 is threadedly sleeved on the screw rod 132. The motor 131 drives the screw rod 132 to rotate, which can realize the lifting and lowering of the jacking rod 12, thereby realizing the height adjustment of the operating head 4. This design makes the lifting and lowering of the rod body more convenient and quick, greatly improves the working efficiency, and also reduces the risk and labor intensity of manual operation. A rechargeable and dischargeable battery 133 electrically connected to the motor 131 is arranged inside the support rod 1, and a charging port is arranged on the support rod 1, which avoids the problem of relying on an external power supply in the traditional way, making the adjustable resistance live working rod more independent and convenient, and can be self-sufficient in various environments. It should be noted that a controller is arranged in the support rod 1, and the operator can remotely control the lifting and lowering, and the operation is safer; In order to improve the stability of the lifting rod 12 when it is being raised or lowered, a guide groove 121 is opened on the outer wall of the lifting rod 12 along the length direction of the lifting rod 12, and a guide block 14 sliding in the guide groove 121 is fixed on the inner wall of the support rod 1. The lifting rod 12 has higher stability when it is being raised or lowered, so that the operating head 4 can better control the opening and closing of the switch on the transmission line. This design can effectively prevent the rod body from shaking or deviating from the track, thereby ensuring the safety and accuracy of the operation.

[0026] For further information, see Figure 3 , Figure 4 and Figure 8 The connecting head 3 includes a fixing ring 31 fixed to the end of the supporting rod 1 and one end of the mounting sleeve 21, one end of the mounting sleeve 21 can be movably inserted in the interior of the fixing ring 31, a U-shaped plate 32 is installed on the outer wall of the fixing ring 31, both ends of the U-shaped plate 32 are fixed to the outer wall of the fixing ring 31, a fixing rod 33 is movably inserted on the U-shaped plate 32, a fixing groove 23 is opened on the outer wall of the mounting sleeve 21 facing away from the end of the connecting head 3, one end of the fixing rod 33 movably passes through the fixing ring 31 and is inserted in the interior of the fixing groove 23. When splicing the extension rod 2, one end of the mounting sleeve 21 is inserted in the interior of the fixing ring 31, and then the fixing rod 33 is moved so that one end of the fixing rod 33 is inserted in the interior of the fixing groove 23. At this time, the mounting sleeve 21 can be fixed in the interior of the fixing ring 31, with high stability and safer when the device is used. Specifically, a baffle 34 fixedly sleeved on the fixing rod 33 is arranged in the opening of the U-shaped plate 32, and a spring 35 sleeved on the fixing rod 33 is connected between the baffle 34 and the opening side of the U-shaped plate 32. Under the elastic force of the spring 35, the baffle 34 is pushed to contact the outer wall of the fixing ring 31, so that one end of the fixing rod 33 is stably inserted into the inside of the fixing groove 23, and the stability of the connection between the installation sleeve 21 and the fixing ring 31 is higher; Specifically, one end of the fixing rod 33 is configured as an inclined surface, and the outer peripheral side of one end of the mounting sleeve 21 is rounded. During installation, the mounting sleeve 21 is directly inserted into the interior of the fixing ring 31, and the side edge of one end of the mounting sleeve 21 contacts the inclined surface of one end of the fixing rod 33, which drives the fixing rod 33 to move until one end of the mounting sleeve 21 is completely inserted into the interior of the fixing ring 31, and one end of the fixing rod 33 corresponds to the fixing groove 23. Under the elastic force of the spring 35, one end of the fixing rod 33 is inserted into the interior of the fixing groove 23 to complete the connection, making the installation more convenient. More specifically, the fixing groove 23 is annular. The advantage of this design is that no matter at what angle the installation sleeve 21 is inserted into the interior of the fixing ring 31, the fixing rod 33 can be inserted into the interior of the fixing groove 23 to complete the connection, and the installation is more convenient.

[0027] See also Figure 2 One end of the mounting rod 22 is provided with a threaded groove, and the operating head 4 is threadedly inserted into the inner part of the threaded groove, so as to facilitate the installation and disassembly of the operating platform 4.

[0028] For further information, see Figure 2 and Figure 4 Limiting rings 24 are fixed on the inner walls of both ends of the mounting sleeve 21. The inner diameter of the limiting ring 24 is slightly larger than the diameter of the jacking rod 12, and the diameter of the mounting rod 22 is slightly smaller than the inner diameter of the limiting ring 24. A limiting block 25 with the same inner diameter as the mounting sleeve 21 is fixed at one end of the mounting rod 22. Under the limitation of the two limiting rings 24, the limiting block 25 is always located between the two limiting rings 24, which ensures the safety of the stroke, avoids the mounting rod 22 from being separated from the mounting sleeve 21 during jacking, and is also convenient for carrying and storage.

[0029] For further information, see Figure 2 , Figure 5 and Figure 6 The supporting leg 11 is hinged at the end of the supporting rod 1, and a plurality of evenly distributed blocking blocks 15 are fixed on the outer side wall of one end of the supporting leg 11. The plurality of blocking blocks 15 correspond to the plurality of supporting legs 11 one by one. The setting of the blocking blocks 15 can limit the rotation angle of each supporting leg 11 to ensure that the plurality of supporting legs 11 stably support the device on the ground. A storage rod 16 is fixed at one end of the supporting rod 1. The storage rod 16 is magnetic, and a magnetic strip 17 is embedded on the supporting leg 11. When the device is not in use, the supporting leg 11 can be adsorbed with the storage rod 16. The plurality of supporting legs 11 are located on the same straight line as the supporting rod 1, which is convenient for carrying and storage.
