[0030] The specific arrangement and function of the installation structure 5 and the auxiliary structure 6 will be described in detail below.

[0031] Reference Figure 1-Figure 4 As shown, in this embodiment: the mounting structure 5 includes eight rectangular blocks 501 fixedly connected to the surface of the protector body 1, and the eight rectangular blocks 501 are grouped in pairs. The inside of the two rectangular blocks 501 is slidably connected with a slide plate 503, and the sides of the two slide plates 503 close to each other are fixedly connected with a limit block 505, and the inside of the limit block 505 is rotatably connected with a rotating shaft 508, and the side wall of the rotating shaft 508 is fixedly connected with a limit wheel 506, and the side wall of the limit wheel 506 is fixedly connected with three barbs 507. When the wire 4 is inserted tightly into the bottom side of the mounting hole 3, the wire 4 is pulled in the opposite direction. In the process of pulling the wire 4 in the opposite direction, the skin of the wire 4 will be sheathed on the surface of the barb 507, thereby increasing the resistance when pulling the wire 4, and improving the stability of the installation and use of the wire 4. The end of the slide plate 503 away from the limit block 505 is fixedly connected with a pull plate 502, and two first springs 504 are fixedly connected between the pull plate 502 and the rectangular plate. The slide plate 503 is subjected to the elastic force of the first spring 504 between the pulling plate 502 and the rectangular plate to drive the limiting block 505 and the limiting wheel 506 to be closely attached to the side wall of the electric wire 4 .

[0032] The side wall of the rotating shaft 508 is evenly provided with a plurality of slots 509, the side wall of the limiting block 505 is fixedly connected with a connecting block 510, and the inside of the connecting block 510 is slidably connected with an insert frame 511, and the size of the insert frame 511 is adapted to the size of the slot 509. The rotating shaft 508 is rotated, and after the barbs 507 on the two relative limiting wheels 506 are rotated to the side close to each other, the insert frame 511 is inserted into the inner wall of the corresponding slot 509 on the rotating shaft 508, and the position of the rotating shaft 508 after rotation can be fixed. The side where the insert frame 511 and the connecting block 510 are close to each other is fixedly connected with a second spring 512. The insert frame 511 is inserted into the inner wall of the corresponding slot 509 on the rotating shaft 508 under the elastic force of the second spring 512.

[0033] Reference Figure 2 and Figure 5As shown, specifically, the auxiliary structure 6 includes a positioning block 61 fixedly connected to the side wall of the protector body 1, a moving bar 62 is slidably connected inside the positioning block 61, a plate 63 is fixedly connected to the end surface of the moving bar 62, and a copper ring 64 is fixedly connected to the surface of the plate 63. The sliding of the moving bar 62 inside the positioning block 61 plays a role in limiting the moving direction of the plate 63.

[0034] The copper ring 64 is an elliptical ring structure. The tightness of the copper ring 64 pressed on the mounting plate is adjusted to avoid the situation of being too loose or too tight during the sliding of the protector body 1. The internal thread of the positioning block 61 is connected with a driving rod 65, and the driving rod 65 is rotatably connected to the inside of the plate 63. When the driving rod 65 is rotated, the driving rod 65 will push the plate 63 to move.

[0035] Working principle: when it is necessary to install the wire 4 on the protector body 1, first pull the insertion frame 511 inside the connecting block 510, and after pulling the insertion frame 511 out from the inner wall of the slot 509, rotate the rotating shaft 508, rotate the barbs 507 on the two relative limiting wheels 506 to the side close to each other, and then release the insertion frame 511. The insertion frame 511 will be inserted into the inner wall of the corresponding slot 509 on the rotating shaft 508 under the elastic force of the second spring 512. At this time, the position of the rotating shaft 508 after rotation can be fixed. At this time, the wire 4 is inserted into the position between the two relative limiting wheels 506, and the wire 4 will push the two limiting wheels 506 away from each other. When the wire 4 is tightly inserted into the bottom side of the mounting hole 3, pull the wire 4 in the opposite direction, and the slide plate 503 will be driven by the elastic force of the first spring 504 between the pulling plate 502 and the rectangular plate to drive the limiting block 505 and the limiting The limiting wheel 506 is close to the side wall of the wire 4. During the process of pulling the wire 4 in the opposite direction, the skin of the wire 4 will be wrapped around the surface of the barb 507, thereby increasing the resistance when pulling the wire 4 and improving the stability of the installation and use of the wire 4. When it is necessary to pull out the wire 4, the rotating shaft 508 can be rotated to rotate the barbs 507 on the two limiting wheels 506 to the side facing away from each other, thereby facilitating the pulling out of the wire 4 between the two limiting wheels 506. By providing the mounting structure 5, further installation and fixing of the wire 4 in the mounting hole 3 is facilitated, the stability of the wire 4 inserted into the mounting hole 3 for installation is improved, and the situation that the wire 4 is easily slipped off from the inner side of the mounting hole 3 when it is subjected to external force after being installed in the mounting hole 3 is avoided, further improving the stability of the installation and use between the surge protector and the wire 4.

[0036] The slide groove 2 on the protector body 1 is a structure located between the mounting plate in the distribution cabinet for installation and mutual support in traditional technology. However, in this process, the protector body 1 is easily slipped on the mounting plate during the long-term pulling between the protector body 1 and the mounting plate. By rotating the drive rod 65, the drive rod 65 will push the plate 63 to move, wherein the moving bar 62 slides inside the positioning block 61 to limit the moving direction of the plate 63. At this time, the tightness of the copper ring 64 pressed on the mounting plate can be adjusted to avoid the situation where the protector body 1 is too loose or too tight during the sliding process. By setting the auxiliary structure 6, the adjustment of the tightness of the protector body 1 installed on the mounting plate is facilitated, and the use effect of the protector body 1 installed on the mounting plate is further improved.
