During the insertion process, the push block 27 is driven to be inserted into the inside of the clamping rod 25 by pushing the guide rod 28. During the insertion process, since the end of the locking block 31 is semi-arc-shaped, the locking block 31 is contracted to the inside of the cavity 29, and the spring 32 is squeezed to generate elastic force. When the cavity 29 is aligned with the locking block 31, the spring 32 generates elastic force to push the locking block 31 to be inserted into the inside of the guide groove 26 for clamping and fixing. Installation in this way can effectively reduce the impact of the external environment and the problem of rust, thereby improving the installation stability of the power supply lightning arrester body 21.

[0025] Further, such as Figure 4 As shown, a pull rope 41 is fixedly connected to the end of the locking block 31, and a pull handle 42 is fixedly connected to the other end of the pull rope 41; the pull rope 41 is slidably connected to the inside of the guide rod 28; during operation, when the power supply lightning arrester body 21 needs to be disassembled, the pull rope 41 is driven to slide upward by pulling the pull handle 42, so that the pull rope 41 pulls the locking block 31 to retract into the cavity 29, and then the clamping rod 25 is taken out from the inside of the clamping slot 24, so as to quickly disassemble and repair the power supply lightning arrester body 21.

[0026] Further, such as Figure 4 As shown, the inner side wall of the clamping rod 25 is fixedly connected to the limiting plate 51; the end of the pull handle 42 is hinged to the limiting rod 52 through a torsion spring, and is located at the end of the limiting plate 51; during operation, when the pull handle 42 covers the surface of the guide rod 28 and the limiting rod 52 is located at the bottom of the limiting plate 51, the torsion spring generates elastic force to open and clamp the bottom of the limiting plate 51 for limiting. When it needs to be taken out, the limiting rod 52 is pressed to rotate inward, and then the pull handle 42 is pulled to slide outward to drive the pull rope 41 to pop out to the outside, so that the staff can remove the power supply lightning arrester body 21.

[0027] Further, such as Figure 3 As shown, a slide groove 61 is provided at the bottom of the power supply casing 1; a slider 62 is slidably connected to the inner side wall of the slide groove 61; a support rod 63 is fixedly connected to the side end of the slider 62; a protective coil plate 64 is fixedly connected to the top of the support rod 63; a wire hole 65 is provided inside the protective coil plate 64, and there are several wire holes; when working, the protective coil plate 64 and the wire hole 65 are installed at the end of the power supply casing 1, so that the cable connected from the inside of the power supply casing 1 passes through the wire hole 65, and then the distance between the slider 62 and the support rod 63 is adjusted to support the end of the cable, thereby reducing the problem of surface damage caused by long-term bending of the cable.

[0028] Further, such as Figure 3 As shown, the end of the protective coil plate 64 is fixedly connected with a protective rod 71, and is arranged in a circular array; the protective rod 71 is located at the end of the wire hole 65; during operation, when the cable passes through the wire hole 65, the protective rod 71 is squeezed so that the protective rod 71 opens to the outside and is clamped on the surface of the cable, thereby achieving a secondary support and protection effect.

[0029] Further, such as Figure 3 As shown, the end of the protective rod 71 is rotatably connected with a ball 72; the end of the locking block 31 is semi-arc-shaped and matches the guide groove 26; when working, by installing a ball 72 on the end of the protective rod 71, when the cable is in the refueling protective rod 71, the cable rolls and moves quickly through the ball 72, thereby achieving a wear-resistant effect.

[0030] Working principle: During operation, when the power supply lightning arrester body 21 needs to be installed, the power supply lightning arrester body 21 is placed at the bottom of the power supply housing 1, and then the mounting block 22 and the mounting plate 23 are aligned with each other, and then the clamping rod 25 is threadedly connected to the inside of the clamping slot 24. During the insertion process, the push block 27 is driven to be inserted into the inside of the clamping rod 25 by pushing the guide rod 28. During the insertion process, since the end of the locking block 31 is semi-arc-shaped, the locking block 31 is contracted into the inside of the cavity 29, and the spring 32 is squeezed to generate elastic force. When the cavity 29 is aligned with the locking block 31, the spring 32 is elastic. The spring 32 generates elastic force to push the lock block 31 into the inside of the guide groove 26 for clamping and fixing. Installation in this way can effectively reduce the impact of the external environment and the problem of rust, thereby improving the installation and stability of the power supply lightning arrester body 21; when the power supply lightning arrester body 21 needs to be disassembled, the pull rope 41 is driven to slide upward by pulling the pull handle 42, so that the pull rope 41 pulls the lock block 31 to retract into the cavity 29, and then the clamping rod 25 is taken out from the inside of the clamping slot 24 to quickly remove the power supply lightning arrester body 21 Disassembly and maintenance processing; when the handle 42 covers the surface of the guide rod 28, the limit rod 52 is located at the bottom of the limit plate 51, and the torsion spring generates elastic force to open, so as to be clamped at the bottom of the limit plate 51 for limiting. When it needs to be taken out, the limit rod 52 is pressed to rotate inward, and then the handle 42 is pulled to slide outward to drive the pull rope 41 to pop out to the outside, so that the staff can remove the power supply lightning arrester body 21; by installing a protective coil plate 64 and a wire hole 65 at the end of the power supply housing 1, the cables connected to the power supply housing 1 can be easily removed. The cable is passed through the wire hole 65, and then the distance between the slider 62 and the support rod 63 is adjusted to support the end of the cable, thereby reducing the problem of surface damage caused by long-term bending of the cable. When the cable passes through the wire hole 65, the protective rod 71 is squeezed to open outward to clamp the surface of the cable, thereby achieving secondary support and protection. A ball 72 is installed at the end of the protective rod 71, and when the cable is refueling the protective rod 71, the cable rolls and moves quickly through the ball 72, thereby achieving a wear-resistant effect.
