Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0023] Reference Figure 1 - Figure 5A clamping device for wiring lightning protection street lamps includes a connecting plate 1, a rotating column 2 is symmetrically connected to the inside of the connecting plate 1, and a fixing ring 3 is rotatably connected to the outside of the two rotating columns 2. The two fixing rings 3 cooperate with each other, and a clamping mechanism is provided inside the fixing ring 3. The clamping mechanism includes a clamping assembly and an installation assembly. The clamping assembly and the installation assembly cooperate with each other. The clamping assembly includes an arc groove 41, which is symmetrically opened on the top of the two fixing rings 3. A placement groove 42 is opened on one side of the inside of the arc groove 41, and an arc spring 43 is slidably connected to the inside of the arc groove 41. The two arc springs 43 on the same side are fixedly connected to a pressing ball 44 at one end close to each other. The mounting assembly includes a fixed block 51, which is fixedly connected to the outside of one of the fixing rings 3. A connecting column 52 is fixedly connected to the outside of the other of the two fixing rings 3. A sliding rod 53 is fixedly connected to the inside of the fixed block 51. A fixing spring 54 is sleeved on the outside of the sliding rod 53. A sliding block 55 is slidably connected to the outside of the sliding rod 53. An insertion rod 511 is fixedly connected to the top of the sliding block 55. A limiting plate 56 is fixedly connected to the inside of the fixed block 51. A rotation groove 57 is defined on the outside of the connecting column 52. A connecting ring 58 is sleeved on the outside of the rotation groove 57. An L-shaped rod 59 is fixedly connected to the outside of the connecting ring 58. A slot 510 is defined on the end of the L-shaped rod 59 near the fixed block 51. An avoidance groove 512 is defined on the top of the fixed block 51.

[0024] In the above technical solution, considering that when workers are looking for tools such as insulating tape, they may easily mix up the wires they have found due to the large number of wires, causing inconvenience to subsequent wiring, in order to solve this problem, the specific operations are as follows:

[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, the L-shaped rod 59 drives the connecting ring 58 to rotate inside the rotating groove 57 until the L-shaped rod 59 is inserted into the interior of the fixed block 51. Under the tension of the fixing spring 54, the sliding block 55 can be pushed in the direction close to the L-shaped rod 59 until the insertion rod 511 is completely inserted into the interior of the slot 510. At this time, the installation work between the two fixing rings 3 is completed, the fixing ring 3 is installed and fixed on the outer wall of the street lamp, and then the two wires to be connected are placed into the interior of the placement groove 42 respectively. Under the extrusion of the arc spring 43, the wires can be squeezed into the interior of the arc groove 41. Through the provided wiring mechanism, the wires to be connected can be classified and fixed before wiring, and then there will be no line confusion during subsequent connection. At the same time, it also avoids the situation where the staff has to hold the wires for connection all the time, ensuring the efficiency and accuracy of wiring, simple structure and strong practicality.

[0026] Reference Figure 1 - Figure 5In a preferred embodiment, a rubber layer is fixedly attached to the outer side of the pressing ball 44 to increase friction. A rubber ring 6 is fixedly attached to the inner walls of both fixing rings 3. The dimensions of the insertion rod 511 match those of the slot 510, and the slot 510 and the insertion rod 511 cooperate with each other. The rubber layer increases friction between the pressing ball 44 and the wires, while the rubber ring 6 increases friction between the fixing ring 3 and the lamppost, improving stability.

[0027] Working principle: In actual use, the staff first puts the two fixing rings 3 on the outer wall of the street lamp post, and then rotates the L-shaped rod 59 so that the L-shaped rod 59 drives the connecting ring 58 to rotate inside the rotating groove 57 until the L-shaped rod 59 is inserted into the inside of the fixed block 51. Under the tension of the fixing spring 54, the sliding block 55 can be pushed in the direction close to the L-shaped rod 59 until the insertion rod 511 completely enters the inside of the slot 510. At this time, the installation work between the two fixing rings 3 is completed, and the fixing ring 3 is installed and fixed on the outer wall of the street lamp. Then, the two wires to be connected are placed into the inside of the placement groove 42 respectively. Under the extrusion of the arc spring 43, the wires can be squeezed into the inside of the arc groove 41. Then the staff goes to find tools such as insulating tape, and then connects the two wires. The connection work of multiple wires can be performed back and forth multiple times.
