[0028] It is worth mentioning that the support seat 2 includes a first support splint 23 and a second support splint 24. The first support splint 23 and the second support splint 24 are provided with a concave cavity 25. The concave cavity 25 is provided with a first through hole 251 and a second through hole 252. The rack 12 is arranged in the first through hole 251, and the second through hole 252 is provided with a bushing 253. The guide column 21 is fixed in the concave cavity 25. The side wall of the concave cavity 25 is provided with a shaft 254. The concave cavity 25 is provided with a top plate 255. The top plate 255 is provided with a third through hole 256. The outer wall of the first support splint 23 and the second support splint 24 is provided with a baffle 26. The first support splint 23 and the second support splint 24 are provided with a support frame 27. The support frame 27 is provided with a first fixing hole 271. The first support splint 23 and the second support splint 24 are hinged. The plate 24 embraces the electric pole, and the concave cavity 25 provides accommodation space for the guide column 21, the spring 13, and the drive assembly 5, which plays a protective role. The first through hole 251 is used in conjunction with the rack 12, and the bushing 253 reduces the wear of the worm 52 and the second through hole 252, and fills the gap between the worm 52 and the second through hole 252, thereby reducing the problem of rust of the worm 52 in the concave cavity 25. The shaft 254 is used in conjunction with the gear 51, and the top plate 255 undertakes the function of the worm 52. The third through hole 256 is used in conjunction with the cylinder 54. The baffle 26 plays a role of dust and rain protection, and prevents the spring 13, the drive assembly 5 and other components from rusting and aging. The support frame 27 provides support for the support plate 3, and the first fixing hole 271 is used in conjunction with the second fixing hole 71;

[0029] It is worth mentioning that the support plate 3 is provided with a connecting piece 31, the connecting piece 31 is provided with a clearance through hole 32, the support frame 27 is arranged in the clearance through hole 32, the connecting piece 31 is provided with a second mounting hole 33, the first fixing hole 271 is provided with a fixing bolt 6, and passes through the second mounting hole 33, so that the support plate 3 and the support frame 27 are connected and fixed, and the support plate 3 is provided with a bubble level 34, through the fixing bolt 6, a clamping force is formed between the connecting pieces 31, so that the support frame 27 arranged in the clearance through hole 32 is clamped by the connecting piece 31, and the connection and fixation of the support plate 3 and the support frame 27 are completed. Since the first support clamping plate 23 and the second support clamping plate 24 are both provided with a driving assembly 5, the bubble level 34 can be used to facilitate the installer to observe whether the support plate 3 is tilted, so as to make adjustments;

[0030] It is worth mentioning that the driving assembly 5 includes a gear 51 and a worm 52. The gear 51 is sleeved on the shaft 254 and meshes with the rack 12. The worm 52 is arranged on the bushing 253, abuts against the top plate 255, and meshes with the gear 51. The worm 52 is provided with a hexagonal groove 53. The worm 52 is provided with a cylinder 54 and inserted into the third through hole 256. The gear 51 rotates in the direction of the axis of the shaft 254. The hexagonal groove 53 is convenient for the installer to rotate the worm 52 by using a hexagonal tool, which provides a convenient installation. The cylinder 54 makes the worm 52 rotate with the third through hole 256 as the axis 254. Since the gear teeth of the gear 51 are straight line profiles and the gear teeth of the worm 52 are spiral line profiles, the profile shapes of the two are different. From the working principle of the worm 52 and the turbine, it can be concluded that the gravity applied to the support seat 2 by the primary and secondary fusion column mounted circuit breaker body 4 cannot rotate the gear 51, and thus cannot drive the worm 52 to rotate, thereby ensuring that the support seat 2 stably maintains the adjusted height size;

[0031] It is worth mentioning that the shapes of the first fixing clamp 14, the second fixing clamp 15, the first supporting clamp 23, and the second supporting clamp 24 are set to be semi-circular, and the first fixing clamp 14, the second fixing clamp 15, the first supporting clamp 23, and the second supporting clamp 24 are provided with a fixing member 7, the fixing member 7 is provided with a second fixing hole 71, and the second fixing hole 71 is provided with a fixing bolt 6, so that the first fixing clamp 14 and the second fixing clamp 15, the first supporting clamp 23 and the second supporting clamp 24 are connected and fixed, so that a wrapping pole is formed between the first fixing clamp 14 and the second fixing clamp 15 The hole formed between the first supporting clamp plate 23 and the second supporting clamp plate 24 is larger than the hole formed between the first fixing clamp plate 14 and the second fixing clamp plate 15. The semi-circular design is more in line with the outer dimensions of the electric pole. The first fixing clamp plate 14 and the second fixing clamp clamp the electric pole through the second fixing hole 71 in conjunction with the fixing bolt 6. The first supporting clamp plate 23 and the second supporting clamp plate 24 embrace the electric pole. However, the hole formed between the first supporting clamp plate 23 and the second supporting clamp plate 24 is larger than the electric pole. However, the formed hole does not fit the electric pole, which facilitates the up and down movement of the support base 2.

[0032] The use principle of the utility model is now described as follows:

[0033] First, fit the first fixing clamp plate 14 and the first supporting clamp plate 23 to the outer wall of the electric pole, rotate the second fixing clamp plate 15 and the second supporting clamp plate 24 to abut against the first fixing clamp plate 14 and the second supporting clamp plate 24, place the fixing bolt 6 in the second fixing hole 71, and tighten it so that the first fixing clamp plate 14 and the second fixing clamp plate 15 form a clamping force to wrap the electric pole, so that the fixing seat 1 is fixed to the electric pole, take the supporting plate 3, insert the supporting frame 27 into the making way through hole 32, set the fixing bolt 6 in the first fixing hole 271, connect and fix the supporting plate 3 and the supporting frame 27, and install and fix the main body 4 of the circuit breaker on the primary and secondary fusion column to the supporting plate 3;

[0034] When it is necessary to adjust the height of the support base 2, insert the hexagonal groove 53 on the first supporting clamp plate 23 and the second supporting clamp plate 24, and rotate them in the same direction to make the gear 51 rotate synchronously, and then make the gear 51 move on the rack 12, and the spring 13 provides a balancing force for the support base 2, so that the support base 2 can move smoothly, and when the retaining ring 22 abuts against the bottom of the first fixing clamp plate 14 and the second fixing clamp plate 15, the support base 2 has been adjusted to the highest height; when the first supporting clamp plate 23 and the second supporting clamp plate 24 abut against the first fixing clamp plate 14 and the second fixing clamp plate 15, the support base 2 has been adjusted to the lowest height. Due to the inconsistent weight of various parts of the circuit breaker body 4 on the primary and secondary fusion column, it is necessary to fine-tune the fixation of the first supporting clamp plate 23 and the second supporting clamp plate 24 through the bubble level 34, and then adjust the left and right balancing force of the support plate 3, so that the fixed base 1 and each component are subjected to balanced force to ensure the fixing stability.

[0035] The above design scheme can make the product have the advantages of easy adjustment, good practicality and reliable fixation.

[0036] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions.
