[0031] By adopting the above technical solution, the protective cover body 7 is driven to close by rotating the rotating shaft 6. When the protective cover body 7 is closed, the blocking block 51 will be driven to insert into the inside of the card slot 53 inside the card seat 54. At this time, the blocking block 51 will squeeze the card pin 523, and the card pin 523 drives the limit plate 2 522 and the spring 2 521 and embeds into the inside of the card seat 54. When the card pin 523 is aligned with the card hole 55, the spring 2 521 rebounds, thereby driving the card pin 523 to insert into the inside of the card hole 55, thereby achieving the fixation of the protective cover body 7.

[0032] Specifically, the fixing assembly 52 includes a second spring 521, a second limiting plate 522 and a latch 523. The second spring 521 is installed inside the holder 54, the other end of the second spring 521 is installed with a second limiting plate 522, and the other end of the second limiting plate 522 is installed with a latch 523.

[0033] By adopting the above technical solution, when the protective cover body 7 is closed, the block 51 will be driven to insert into the inside of the slot 53 inside the socket 54. At this time, the block 51 will squeeze the pin 523, and the pin 523 will drive the limit plate 2 522 and the spring 2 521 and embed into the inside of the socket 54. When the pin 523 is aligned with the hole 55, the spring 2 521 rebounds, thereby driving the pin 523 to insert into the inside of the hole 55.

[0034] When the present embodiment is in use, the protective cover body 7 is driven to close by rotating the rotating shaft 6. When the protective cover body 7 is closed, the blocking block 51 will be driven to insert into the inside of the blocking groove 53 inside the socket 54. At this time, the blocking block 51 will squeeze the blocking pin 523. The blocking pin 523 drives the limiting plate 2 522 and the spring 2 521 and embeds into the inside of the socket 54. When the blocking pin 523 is aligned with the blocking hole 55, the spring 2 521 rebounds, thereby driving the blocking pin 523 to insert into the inside of the blocking hole 55, thereby fixing the protective cover body 7.

[0035] Working principle and use process of the utility model: When the utility model is used, when fixing the electrical processing handle body 4, the fixing rod 31 is pressed, the fixing rod 31 compresses the spring 32 and is embedded in the fixing block 33, and then the fixing block 33 is inserted into the fixing groove 35. When the fixing rod 31 is aligned with the fixing hole 36, the spring 32 rebounds, thereby driving the fixing rod 31 to be inserted into the fixing hole 36, so that the current transformer body 1 and the electrical processing handle body 4 can be connected and fixed, and the button 342 is pressed, and the button 342 drives the limit plate 343 to be inserted into the mounting hole 341. The protective cover body 7 is driven to be closed by rotating the rotating shaft 6. When the protective cover body 7 is closed, the clamping block 51 is driven to be inserted into the inside of the clamping groove 53 inside the clamping seat 54. At this time, the clamping block 51 will squeeze the clamping pin 523, and the clamping pin 523 drives the limiting plate 2 522 and the spring 2 521 and is embedded in the inside of the clamping seat 54. When the clamping pin 523 is aligned with the clamping hole 55, the spring 2 521 rebounds, thereby driving the clamping pin 523 to be inserted into the inside of the clamping hole 55, so that the protective cover body 7 can be fixed.
