[0028] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0032] See also Figure 1 , Figure 1The schematic diagram of the structure of an insulator string is shown. The insulator string includes a plurality of insulators 60 connected in sequence. The insulator 60 includes an insulator body 61, a metal cap 62 and a connecting pin 63. The metal cap 62 is arranged on the insulator body 61 and has a mounting cavity 621. The metal cap 62 also has a notch 622 and a plug hole (not shown). The notch 622 and the plug hole are arranged opposite to each other and are both connected to the mounting cavity 621. The connecting pin 63 is arranged on the side of the insulator body 61 away from the metal cap 62. Among any two adjacent insulators 60, the connecting pin 63 of one insulator 60 is inserted into the mounting cavity 621 of the other insulator 60. The pin is inserted into the notch 622 and the plug hole, and the connecting pin 63 is fixed in the mounting cavity 621 to achieve a stable connection between the two adjacent insulators 60. Since the structure of the insulator string is compact and the pin is located between the two adjacent insulators 60, the operating space for disassembling and assembling the pin is relatively narrow.

[0033] As mentioned in the background technology, there are two main methods for disassembling and assembling pins in the industry: the first method is to use a knocking tool to knock the pin out from one end, and then knock the pin in and install it after the insulator 60 is replaced, which is simple to operate; however, due to the narrow operating space when disassembling and assembling the pin, this method is easy to accidentally knock the insulator 60 or cause damage to the insulator 60 or the pin due to improper force. The second method is to use professional tools, such as pin pliers or mechanical pin pullers, to perform disassembly and assembly operations. This method can reduce damage to the insulator 60, but requires manual external force, and due to the narrow operating space, the operation process is still not convenient enough, resulting in low efficiency in replacing the insulator 60.
