Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-5The climbing foot spike for an electric power tower shown in the figure comprises a connecting plate 2 mounted on a mounting plate 1, a foot spike 3 being connected to one side of the connecting plate 2, an elastic buckle 4 being sleeved on the middle of the foot spike 3, a support rod 5 being fixedly connected to the lower end of the elastic buckle 4, a limiting axis 6 being arranged at the bottom of the support rod 5, a fixing plate 7 being fixedly connected to one side of the limiting axis 6, a first locking bolt 8 being arranged through the fixing plate 7 and the mounting plate 1, a second locking bolt 9 being arranged through the mounting plate 1 and the connecting plate 2, the mounting plate 1, the connecting plate 2 and the foot spike 3 in this embodiment are all existing structures of climbing foot spikes, the mounting plate 1 is equivalent to an installed iron tower, and the arrangement of the elastic buckle 4 and the support rod 5 between the foot spike 3 and the mounting plate 1 allows the tripod to form a triangular structure with the mounting plate 1, and the stability characteristics of the triangle are utilized to improve the stability of the tripod during use.

[0026] Both ends of the elastic buckle 4 are provided with clamping rings 10, one side of one of the clamping rings 10 is fixedly connected to a limiting plate 11, and the limiting plate 11 is distributed relatively to the other clamping ring 10. The support rod 5 is connected to the foot nail 3 through the elastic buckle 4, which is convenient for adjusting the angle of the support rod 5 on the foot nail 3 and flexibly rotating the use angle of the support rod 5. Afterwards, by using the two clamping rings 10 and the limiting plate 11 on the elastic buckle 4, it is convenient to perform shock-absorbing treatment on the connection between the foot nail 3 and the support rod 5, thereby increasing the connection firmness between the support rod 5 and the foot nail 3.

[0027] A through groove 13 is provided at the end of the support rod 5, and the limit shaft 6 includes a limit seat 17 fixedly connected to the fixed plate 7. The same limit bolt 12 is connected through the through groove 13 and the limit seat 17. By using the limit bolt 12 and the limit seat 17 in the limit shaft 6, it is convenient to increase the connection structure on the fixed plate 7, so that the through groove 13 can be inserted into the middle of the two limit seats 17, and the structure is assembled by the penetration of the same limit bolt 12, and then the support rod 5 is fixed to one side of the fixed plate 7 by tightening the nut at the end of the limit bolt 12.

[0028] The screw end of the first locking bolt 8 is tilted downward, and the screw end of the second locking bolt 9 is tilted upward. The first locking bolt 8 and the second locking bolt 9 are relatively distributed. The first locking bolt 8 is convenient for increasing the connection structure between the fixed plate 7 and the mounting plate 1, so that the first locking bolt 8 and the second locking bolt 9 can be inserted into the power tower of the mounting plate 1 to connect the support rod 5 with the mounting plate 1, and the position of the foot nail can be fixed. The second locking bolt 9 can increase the inclined connection end between the foot nail 3 and the mounting plate 1. Through the relative inclined setting of the first locking bolt 8 and the second locking bolt 9 and the mounting plate 1, the connection firmness between the connecting plate 2 and the fixed plate 7 and the mounting plate 1 can be increased, and the secondary supporting structure of the foot nail can be increased.

[0029] The first locking bolt 8 includes a locking sleeve 14 which is connected through the fixing plate 7 and the mounting plate 1, a through bolt 15 is connected through the locking sleeve 14, and a sealing sleeve 16 is sleeved between the screw head end of the through bolt 15 and the locking sleeve 14. The use of the locking sleeve 14 facilitates the increase of the diameter expansion structure of the outside of the through bolt 15, so that when the through bolt 15 is screwed into the locking sleeve 14, the locking sleeve 14 will be expanded to increase the diameter of the locking sleeve 14, increase the connection firmness between the locking sleeve 14 and the through structure, and improve the connection stability between the foot nail and the power tower.

[0030] The outer surface of the locking sleeve 14 is covered with a frosted layer, and expansion grooves are provided on both sides of the locking sleeve 14. A limiting disk is provided at the end of the locking sleeve 14, and the locking sleeve 14 is limitedly engaged with the fixing plate 7 through the limiting disk. The setting of the frosted layer is convenient for increasing the friction between the locking sleeve 14 and the penetration structure. The use of the limiting disk facilitates the limited penetration of the locking sleeve 14 and the fixing plate 7. The opening of the expansion groove facilitates the screwing in of the penetration bolt 15 to increase the diameter of the locking sleeve 14, thereby improving the connection firmness between the first locking bolt 8 and the connecting component.

[0031] The second locking bolt 9 has the same structure as the first locking bolt 8. The through bolt 15 in the second locking bolt 9 is through-connected with the connecting plate 2 and the mounting plate 1. The locking sleeve 14 in the second locking bolt 9 is through-connected with the mounting plate 1 and the connecting plate 2. The same structural setting of the second locking bolt 9 and the first locking bolt 8 facilitates the through-use of the second locking bolt 9 and the first locking bolt 8 with the mounting plate 1, thereby increasing the installation convenience between the foot nail structure and the power tower.

[0032] How this utility works:

[0033] When in use, the existing installation technology of the tripod and the power tower is applied. A screw is used to penetrate the connecting plate 2 and then screwed into the mounting plate 1. The end of the screw is tightened and fixed by the support rod 5. Then the support rod 5 with the front end of the foot nail 3 is fitted with the fixing plate 7. The through groove 13 at the end of the support rod 5 is inserted into the two limit seats 17 on the fixing plate 7. Then the limit bolt 12 is used to penetrate the limit seat 17 and the through groove 13. Then the nut is sleeved at the end to tighten and fix it, so that the inclination angle of the support rod 5 can be limited. The support rod 5 and the foot nail 3 are arranged in a triangular structure on the mounting plate 1 for use. The triangular structure between the support rod 5 and the foot nail 3 and the mounting plate 1 is connected at the end, so that the auxiliary support structure at the bottom of the foot nail can be added to improve the support stability of the foot nail. Then the first locking The locking sleeve 14 in the bolt 8 penetrates the fixing plate 7 and the mounting plate 1. After the limiting plate at the end of the locking sleeve 14 is fitted with the surface of the fixing plate 7, the penetration bolt 15 penetrates the locking sleeve 14. By using a screwdriver to tighten the penetration bolt 15 to the mounting plate 1, the penetration bolt 15 opens the expansion groove of the locking sleeve 14, expands the diameter of the locking sleeve 14, and makes the outer surface of the locking sleeve 14 close to the groove wall of the fixing plate 7 and the mounting plate 1. The first locking bolt 8 penetrates and connects the fixing plate 7 and the mounting plate 1. Then, the second locking bolt 9 is penetrated through the connecting plate 2 and the mounting plate 1 by the same method, and the foot nail is fixed to the power tower on which the mounting plate 1 is located, thereby completing the position fixation of the foot nail on the power tower, increasing the connection firmness between the foot nail and the power tower, improving the use effect of the foot nail, and having practicality.
