A support shaft 4 is installed inside the fixed seat 3 through a bearing. The vertical part of the support shaft 4 is provided with a lightning arrester body 5.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , An anti-wind mechanism 6 is jointly provided on the support shaft 4 and the fixed seat 3. The anti-wind mechanism 6 includes a support spring 61. The inner side wall of the fixed seat 3 is welded with a support spring 61. The other end of the support spring 61 is fixedly connected to the vertical part of the support shaft 4. Two symmetrically distributed protective pads 62 are fixedly connected to the inner side wall of the fixed seat 3. A damping hole 63 is opened in the horizontal part of the support shaft 4. A support plate 64 is fixedly connected to the surface of the fixed seat 3 and below the horizontal part of the support shaft 4. An elastic member 65 is bonded to the upper end of the support plate 64. The other end of the elastic member 65 is bonded with a damping rod 66. The damping rod 66 is slidably connected to the damping hole 63. Through the setting of the support spring 61, the support shaft 4 can be connected and used. Under the deformation of the support spring 61, the wind impact can be released to avoid the problem of hard impact and damage of traditional lightning arresters. Under the action of structures such as the damping hole 63 and the damping rod 66, the excess deformation stress generated by the support spring 61 can be worn out to avoid the shaking problem of the support spring 61.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , A plurality of damping holes 63 are provided. The plurality of damping holes 63 are arranged in a circular array on the support shaft 4. Through the setting of the damping holes 63, it is convenient to cooperate with the damping rod 66 for wear. The overall shape of the protective pad 62 is arc-shaped. The protective pad 62 is made of rubber. Through the setting of the protective pad 62, the impact generated by the support shaft 4 can be assisted in buffering, and the rubber material has good tolerance.

[0025] Please refer to Figure 1 , Figure 2 , Figure 4, a disassembly and assembly mechanism 7 is jointly arranged on the triangular base 1 and the fixed seat 3. The disassembly and assembly mechanism 7 includes an insertion block 71. The middle part of the lower end of the fixed seat 3 is fixedly connected with the insertion block 71. The insertion block 71 is slidably connected with the triangular base 1. An insertion plate 72 is slidably connected inside the triangular base 1. The insertion plate 72 is slidably connected with the insertion block 71. A end plate 73 is fixedly connected to the front surface of the insertion plate 72. The end plate 73 contacts the triangular base 1. An elastic cord 74 is fixedly connected to the back surface of the end plate 73. The other end of the elastic cord 74 is fixedly connected with the triangular base 1. There are two elastic cords 74, and the two elastic cords 74 are symmetrically distributed on the end plate 73. Through the arrangement of the elastic cord 74, the end plate 73 can be connected and used. Through the arrangement of structures such as the insertion plate 72 and the elastic cord 74, the insertion block 71 can be inserted, so that the insertion block 71 drives the fixed seat 3 to be stable, and further the lightning arrester body 5 is stable, which is convenient for the operator to disassemble and assemble.

[0026] The specific implementation process of the present utility model is as follows: During use, by pulling the end plate 73 to move away from the triangular base 1, the insertion plate 72 is driven to move, the elastic cord 74 deforms, then the fixed seat 3 is pushed to contact the triangular base 1, so that the insertion block 71 is inserted into the triangular base 1, and the end plate 73 is released to make the elastic cord 74 recover its deformation, so as to pull the insertion plate 72 to insert into the insertion block 71, and the insertion block 71 is inserted and processed, so that the insertion block 71 drives the fixed seat 3 to be stably placed, and further the lightning arrester body 5 is in a stable state, which is convenient for the operator to disassemble and assemble;

[0027] When the lightning arrester body 5 is affected by strong wind convection weather during use, under the impact of the wind force, the lightning arrester body 5 drives the support shaft 4 to deflect, the support spring 61 deforms, and the wind force impact is released. Under the action of the protective pad 62, and the protective pad 62 is made of rubber material, the impact force on the support shaft 4 can be assisted in releasing, avoiding the problem that the traditional lightning arrester body 5 is damaged by hard impact;

[0028] During this process, when the support shaft 4 deflects, the inner wall of the damping hole 63 squeezes the damping rod 66, the damping rod 66 pushes the elastic member 65 to deform, and finally the damping rod 66 disengages from the damping hole 63. Under the action of force, the damping rod 66 moves along the surface of the support shaft 4. When the damping rod 66 slides into the next damping hole 63, the elastic member 65 recovers its deformation to push the damping rod 66 into the damping hole 63. Under the wear effect of the damping hole 63 and the damping rod 66, the excess deformation stress generated by the support spring 61 can be worn, avoiding the problem of excessive jitter of the support spring 61.
