Through the action of the release piece, the block 7 can be retreated into the slide slot 1 6, and the fixed relationship between the connecting block 3 and the base 2 is released, which is convenient for the staff to maintain the lightning arrester.
[0023] The releasing member includes an L-shaped block 8; the side wall of the connecting block 3 is provided with a group of slide grooves 2 9; the slide grooves 2 9 are connected with the card slot 4; the groove wall of the slide groove is slidably connected with the L-shaped block 8; one end of the transverse block of the L-shaped block 8 extends into the card slot 4; a spring is fixedly connected between the L-shaped block 8 and the slide grooves 2 9; during operation, the staff pushes the L-shaped block 8 to slide in the slide grooves 2 9, and the transverse block of the L-shaped block 8 will enter the card slot 4, squeezing the side wall of the card block 7, so that the card block 7 is pushed back into the slide groove 1 6, so that the connecting block 3 can be released on the base 2.
[0024] The card block 7 is set to a trapezoidal shape; when working, the card block 7 is in a trapezoidal shape. When the staff inserts the connecting block 3 from top to bottom into the placement groove 5 of the base 2, the bottom of the connecting block 3 will squeeze the trapezoidal surface of the card block 7. After being squeezed, the trapezoidal surface of the card block 7 will slide into the slide groove 6, so that the bottom of the connecting block 3 contacts the bottom of the placement groove 5. At this time, the card slot 4 corresponds to the notch of the slide groove 6, so that the card block 7 can enter the card slot 4, which simplifies the operation of the staff to install the lightning arrester on the base 2.
[0025] A group of vertical blocks of the L-shaped blocks 8 are fixedly connected to the top of each of the vertical blocks with an oblique rod 10; the oblique rod 10 is provided with a traction groove 11 on the side wall near the main body 1; the outer circular wall of the main body 1 near the bottom is slidably connected with an annular strip 12; a group of extrusion blocks 13 are fixedly connected to the bottom of the annular strip 12; the extrusion blocks 13 match the traction groove 11; during operation, the staff slides the annular strip 12 downward on the main body 1, and the extrusion blocks 13 on the annular strip 12 will slide in the traction groove 11 of the oblique rod 10. Due to the oblique distribution of the oblique rod 10, the oblique rod 10 will be squeezed during the downward sliding of the annular strip 12, so that the oblique rod 10 will drive the L-shaped block 8 to slide in the slide groove 2 9, so that the L-shaped block 8 can push the card block 7, so that the staff can release the card effect of multiple card blocks 7 at the same time, which is convenient for the staff to maintain and inspect the lightning arrester.

[0027] The connecting block 3 is set to be triangular in shape, and the side wall of the connecting block 3 close to the bottom is set to be chamfered; when working, the triangular shape of the connecting block 3 can improve the stability of the lightning arrester installed on the base 2, and the chamfering of the side wall of the connecting block 3 can make the connecting block 3 easily enter the placement groove 5.
[0028] Working principle: by sliding the card block 7 in the slide groove 6, when the staff wants to install the arrester body 1 on the base 2, after inserting the corresponding placement groove 5 of the connecting block 3, the card groove 4 on the connecting block 3 will correspond to the slide groove 6, and one end of the card block 7 will enter the card groove 4 of the connecting block 3 through the elastic force of the spring, so that a fixed relationship is formed between the connecting block 3 and the base 2, so that the body 1 on the connecting block 3 is fixed on the base 2, which plays a role in fixing the arrester, changing the previous method of fixing with screws by the staff. Through the effect of the release piece, the card block 7 can be withdrawn Return to the slide groove 1 6, release the fixed relationship between the connecting block 3 and the base 2, and facilitate the maintenance of the lightning arrester by the staff. The staff pushes the L-shaped block 8 to slide in the slide groove 2 9, and the transverse block of the L-shaped block 8 will enter the card slot 4, squeezing the side wall of the card block 7, so that the card block 7 is pushed back into the slide groove 1 6, so that the connecting block 3 can be released on the base 2. The card block 7 is trapezoidal in shape. When the staff inserts the connecting block 3 from top to bottom into the placement groove 5 of the base 2, the bottom of the connecting block 3 will squeeze the trapezoidal surface of the card block 7, and the trapezoidal surface of the card block 7 is squeezed. After being pressed, it will slide into the slide groove 6, so that the bottom of the connecting block 3 contacts the bottom of the placement groove 5. At this time, the card slot 4 corresponds to the notch of the slide groove 6, so that the card block 7 can enter the card slot 4, which is convenient for the staff to install the lightning arrester on the base 2. The staff slides the annular strip 12 downward on the body 1, and the extrusion block 13 on the annular strip 12 will slide in the traction groove 11 of the oblique rod 10. Due to the oblique distribution of the oblique rod 10, the annular strip 12 will squeeze the oblique rod 10 during the downward sliding process, so that the oblique rod 10 will drive the L-shaped block 8 to slide. Sliding in the groove 2 9 allows the L-shaped block 8 to push the card block 7, allowing the staff to release the blocking effect of multiple card blocks 7 at the same time, which is convenient for the staff to maintain and inspect the lightning arrester. The limit block 14 slides in the limit groove, so that the limit block 14 drives the card block 7 to slide, preventing the card block 7 from popping out of the slide groove 1 6 due to the elastic force of the spring, avoiding trouble for the staff in installing the lightning arrester. The connecting block 3 is triangular in shape, which can improve the stability of the lightning arrester installed on the base 2. The connecting block 3 can be easily inserted into the placement groove 5 by chamfering the side wall of the connecting block 3.
