Thus, when the aperture of the first opening is reduced by the first connection portion 130, the aperture of the first connection port 120 is reduced, so that the body 100 hoops the electric pole 1000, and the first connection port 120 tightly wraps the grounding body 2000; and make the bore of the second connector 220 on the lateral wall of auxiliary connector 200 also diminish to make connect hole 210's diameter diminish, thereby make the hooping pole 1000 that auxiliary connector 200 can be tight, further improved the stability of being connected between protection against rodents structure and the pole 1000, avoid protection against rodents structure to drop from the pole 1000, guarantee protection against rodents effect.
As shown in fig. 1, 4 and 5, in any of the above embodiments, the inner wall of the first through hole 110 is provided with a first contraction opening 111. Thus, when the first connection portion 130 makes the aperture of the first connection port 120 smaller, so that the diameter of the first through hole 110 is smaller, the first contraction port 111 is utilized to make the body 100 have a certain contraction margin and a certain deformation margin, thereby preventing the body 100 from cracking or breaking. Meanwhile, because the contact area of the first protrusion 1111 at the opening of the first contraction port 111 and the electric pole 1000 is small, the friction force between the body 100 and the electric pole 1000 can be increased, and the body 100 is prevented from falling off from the electric pole 1000. Further, the body 100 is made of an elastic body, that is, the body 100 is made of an elastic material such as rubber, soft plastic, etc., and when the diameter of the first through hole 110 is reduced, the body 100 is not easily broken or damaged under the action of elastic contraction; simultaneously, make the body 100 keep away from the edge perk of pole 1000 for body 100 appears loudly, and the inner wall of first through-hole 110 combines inseparabler with pole 1000, and the assembly is more stable.
As shown in fig. 4 and 5, in one embodiment, the first constrictions 111 are shaped as triangles or rectangles. Therefore, the first contraction opening 111 is easily formed in the inner wall of the first through hole 110, and the processing technology is simple and convenient. When first constriction 111 is triangle-shaped or V-arrangement, make the bore of first connection mouth 120 diminish when first connecting portion 130 to make the diameter of first through-hole 110 diminish, the opening part of triangle-shaped or V-arrangement is equipped with two first archs 1111 that relative interval set up, and two first archs 1111 take place slight bending, and the crooked direction deviates from the atress direction of body 100, thereby makes body 100 can tightly grasp pole 1000, has further strengthened the assembly and connection intensity of body 100 with pole 1000.
As shown in FIGS. 1 and 3, in one embodiment, the auxiliary connector 200 is provided with a second constriction 230 communicating with the first constriction 111, and the second constriction 230 cooperates with the first constriction 111 to form a constriction. In this way, when the first connection portion 130 makes the aperture of the first connection port 120 smaller, so that the diameter of the first through hole 110 is smaller, the second contraction port 230 is utilized to make the auxiliary connection body 200 have a certain contraction margin and deformation margin, thereby preventing the auxiliary connection body 200 from being broken or damaged. Meanwhile, since the contact area between the connection transition portion of the opening of the second contraction port 230 and the connection through hole 210 and the pole 1000 is small, the friction force between the auxiliary connection body 200 and the pole 1000 can be increased, and the auxiliary connection body 200 is prevented from falling off from the pole 1000. Further, the auxiliary connector 200 is made of an elastic body, that is, the auxiliary connector 200 is made of an elastic material such as rubber or soft plastic, and when the diameter of the connection through hole 210 is reduced, the auxiliary connector 200 is not easily broken or damaged by elastic contraction. When the first contraction port 111 and the second contraction port 230 are communicated and matched to form a contraction part, the contraction allowance and the deformation allowance of the whole rat-proof structure are larger, and the rat-proof structure is prevented from being broken or damaged due to deformation.
In one embodiment, the second constrictions 230 are shaped as triangles or rectangles. Thus, the second contraction port 230 is easily formed on the sidewall of the auxiliary connection body 200, so that the processing process is simple and convenient. When the second constriction 230 is triangular or V-shaped, when the first connection portion 130 makes the bore of the first connection port 120 smaller, so that the diameter of the connection through hole 210 becomes smaller, the opening of the triangular or V-shaped is provided with two second protrusions arranged at opposite intervals, the two second protrusions are slightly bent, the bending direction deviates from the stress direction of the auxiliary connection body 200, so that the auxiliary connection body 200 can tightly grasp the electric pole 1000, and the assembly connection strength of the auxiliary connection body 200 and the electric pole 1000 is further enhanced.
